The biggest advantage of the lotion tissue is that moisturizing cream ingredients are added to the paper, making the softness of the paper greatly improved.It not only has little stimulation to sensitive skin, but also has the effect of moisturizing. In addition, the production of the paper itself also pays great attention to softness, giving lotion tissue a completely different experience than ordinary paper. Lotion tissue is great for rubbing skin, but not for other uses such as stains.

Usually, glycerin is added to the lotion tissue, glycerin is very hygroscopic, even in a relatively low humidity environment, anhydrous glycerin will still absorb moisture in the air until it reaches a balance with the relative humidity in the air. At the same time, the lotion tissue can dissolve in water and other solvents, and the water absorption of the paper itself will not be affected. If you lick the lotion tissue with your tongue, you will feel a slight sweetness, which is the taste of glycerin.

At present, the lotion tissue that can be seen in the domestic market include Nipiao, Jie soft, unifree, Kexin soft and other brands, and the majority of foreign countries are Japan and South Korea, and most of the products produced in Japan are Dawang paper, Prince paper, and Japanese paper, and there are some smaller manufacturers.  There are also many new brands to join the lotion tissue industry, because the use experience brought by lotion tissue is completely different from ordinary paper.

What is ultra facial cream?

Cream is a description of the state of matter, like we usually say that water is liquid, soil is solid and so on. The counterpart to cream is lotion, which is similar to a state of water but thicker than water, and cream is more viscous than lotion, such as common facial cleansers and moisturizers. A state thicker than cream is called colloidal or colloidal, similar to a semi-solid, and then a solid.

Creams are commonly found in care products and cosmetics, and their main ingredients vary greatly depending on their function.  The use of creams on household paper can also be divided into a variety of categories, such as creams that focus on moisturizing function, creams that focus on smooth series, and functional creams that can play a certain degree of skin care.  But no matter how it’s classified, its basic ingredients haven’t changed much.

In order to improve the added value of paper and product competitiveness, some cream ingredients are also added with squalane, deep-sea sweet oil, aloe vera and other ingredients, which are usually expensive and contain very little in the cream ingredients.

Cream ingredients suitable for household paper composite should follow the following points:

1. Contains the right amount of moisturizing ingredients. Moisturizing ingredients are used to increase the softness and skin feeling of the paper, but it should be noted that excessive moisturizing ingredients may cause a decrease in the strength and thickness of the paper, which will cause trouble for subsequent production.
2. Contains a moderate amount of softener.  The softener referred to here mostly contains silicon components, and the softener can give the paper a soft and smooth performance, making the user feel silky.
3. Contains a moderate amount of fixative. The fixative can well position the cream ingredients on the surface of the paper without penetrating into the inside of the paper, which can reduce the impact of the cream on the physical properties of the paper, and ensure that the cream is effectively transferred to the user’s use site during the use of the user, so as to achieve its due role.
4. Surfactant. Surfactants can effectively blend the different ingredients in the cream, so that the cream ingredients can form a stable mixture.
5. Emulsifier. Depending on the composition of the cream, some cream ingredients may need to be emulsified to form a more stable emulsion for production.
6. Corrosion protection system. Since most of the ingredients in the cream are organic, and most of the cream is moisturizing, the cream household paper is very easy to produce bacteria and mold, and the addition of food-grade anti-corrosion system can effectively avoid this.
   

   How is the cream applied to the paper?

   The cream is applied to the surface of the paper using a special device called a Lotion Applicator. Commonly used Lotion Applicator has spray type compounding machine, roll type compounding machine, spray type compounding machine, extrusion type compounding machine and so on. The composite process can be double-sided composite or single-sided composite, depending on the needs of the product. Spray compounding machine is relatively simple, using high pressure to low viscosity and low consistency of the cream (applied to such equipment cream can be called emulsion) through the nozzle atomized compound to the surface of the paper. The principle of the roller compounding machine is similar to that of the sizing machine, which transfers the cream (or emulsion) to the surface of a roll by two-roll extrusion, and then compacts the cream (or emulsion) to the surface of the paper by roller extrusion. Spray compounding usually uses a high-speed rotating turntable to atomize (cream or emulsion) onto the surface of the paper. The principle of extruded composite machine is similar to that of coated paper coater. The choice of the compounding machine is determined according to the quality requirements of the product and the physical properties of the cream.

   What can lotion tissue give us?

   The lotion tissue gives the paper a softness and smoothness far beyond ordinary paper, and has a certain moisturizing function, and some products also have skin care function.  As far as the feeling is concerned, the cream paper is silky and dry like silk, and the soft feeling like cotton can undoubtedly bring more comfort to users.  From the user’s own point of view, skin allergy patients, rhinitis patients, cold patients, as well as infants and new mothers choose this type of paper is undoubtedly the best choice.

When we make coffee, why do we put it through a coffee filter? What exactly does it do?

Many people like to drink coffee, even brew coffee.When we brew it. If have been watching carefully. Or really understand.You know that many people use coffee filter.Do you know what the filter paper does in brewed coffee?Or would it make it make a difference if coffee was brewed without a filter?

In general coffee filter appear in a hand-brewed coffee maker.Many coffee filters are disposable, and coffee filter are very important for the “ cleanliness” of a cup of coffee.

In the 19th century, there was no real “coffee filter” in the coffee industry. At that time, people drank coffee by adding coffee powder directly into the water, boiling it, and then filtering the coffee grounds. Generally, “metal filter” and “cloth filter” were used as the main method.

But at that time, the technology was not so exquisite. There would always be a thick layer of fine coffee powder at the bottom of the filtered coffee liquid, which would lead to more bitter coffee on the one hand, because the coffee powder at the bottom would slowly release more bitter substances in the coffee liquid. On the other hand, many people at the bottom of the coffee don’t drink it, but just throw it away, resulting in waste.

Later, when coffee was brewed with a filter paper, not only did no residue leak, but the water flowed at the desired speed, neither too slowly nor too fast, affecting the quality of the coffee flavor.

The vast majority of filter paper is disposable, the material is very thin, even after drying it is difficult to use the second time. Of course, there are also some filter paper is used repeatedly, after boiling, you can take out the use of hot water to rinse several times, you can use again.

As a result, when brewing coffee, the filter paper will make the coffee taste stronger and cleaner. In brewing coffee, the role of filter paper can not be replaced, its main role is to prevent coffee powder from falling into the pot, so that the brewed coffee without grounds, so that the coffee flavor can be more clean, no impurities

Coffee filter

Generally coffee filter used to drip coffee, to filter the ground coffee beans and coffee powder and extract the coffee liquid into the cup.Coffee filter also can filter the oil of thwe coffee and get a clean coffee solution. Good filter paper can filter the impurities, and the coffee tastes more mellow and has a more obvious aroma.

Advantages: high convenience, use out immediately lost; Out of the taste is relatively clean; Less impurity and impurity.

Disadvantages: less environmentally friendly use of paper; Unbleached paper will smell like paper; The oil will filter out, resulting in a grease-free taste.

Metal filter

The metal coffee filter allows the fat to be extracted (but not as rich as the concentrate, just some of the thin fat is retained), and the taste is thicker and closer to the original flavor of the beans, which in blind tests was also different from the filter paper. We commonly use metal strainer on the French press pot

Advantages: more environmental protection, through washing and reuse, more can drink the original flavor of coffee, thick taste, save less environmental protection filter paper as long as after use clean and reusable, made of stainless steel is durable and strong.

Disadvantages: Fine powder is easy to cause excessive extraction resulting in excessive bitterness, fine powder will pass through the filter into the coffee, the taste may be slag

Love coffee,

It is elegant life way.

Because love coffee, let us get together.

Different type coffee cup have big different flow rate lead the final coffee flavor, coffee cup affect the flow rate mainly reason because of the hole under the filter and the distribution of the ribs above the filter. For exampl fan-shaped and bowl type,the drip diameter at the bottom of the cup is small and the flow rate is slow.

Coffee filter have bleach and unbleached:

The quality of the filter paper is important to keep the coffee ware clean and the filter flow rate good. Besides, be sure to choose a filter paper suitable for the size of the cup, and pay attention to the thickness and density – too thin and thin filter paper will make the water flow too fast, while too thick or too dense filter paper will filter out more coffee oil.

In use, how do we remove the smell of paper from filter paper?

Ways as below:

1. Put the coffee filter into the coffee machine
2. Put the hot water to wet the paper(Please make sure all paper place is wet)
3. Pour away the hot water, do not use it to boil.
4. If necessary wet again.
5. Start brew coffee

Bamboo fibercontent is high.fiber shape is long,mechanical proterties and plasticity are good.Bamboo as good substitute for wood raw materials.It can be meet the pulp requirements of medium and high grape paper.Research show that,bamboo chemical composition and fiber properties have good pulping properties.bamboo pulp properties second only to coniferous wood pulp,better than broadleaf wood pulp and grass pulp.It’s great significance to develop bamboo pulping and paper making industry,in order to remit the shortage of wood pulp.

Bamboo growing very fast. Orinary 3-4 years can be grow up.And bamboo forest have strong carbon effect,make the bamboo economic benefits,environmental benefits and social benefits are increaseingly prominent. Currenty China bamboo pulp production technology and machine have gradually matured,plane,grinding and other host equipment has realized domestic production.Large and medium-sized bamboo paper production lines have been industrialozed in Guizhou,Sichuan and other place.

Bamboo pulp paper chemical character

As for biomass materials, bamboo have cellulose,hemicellelose,lignin 3 chemical compenent, In addition have a small of pectin,starch,polysaccharide and wax.Through analyzing the chemical composition and characteristics, can be understand bamboo as paper making materials merits and demerits.

1.Bamboo have higher cellulose

Superior finished paper has higher requirements on pulp raw materials. Require collelose content more higher more better. Lignin,polysaccharide and other extracts more lower more better.

2.Bamboo fiber is long, long diamter is laege

The average length of bamboo fiber is 1.49~2.28mm,the average diameter is 12.24~17.32 μm, long diameter ratio as 122~165. The average fiber wall thickness 3.90~5.25 μm. The wall to cavity is 4.20~7.50. They are belong thick-walled fibers with large length and diameter.Paper pulp materials mainly on cellulose of biomass materials for paper making require high cellulose content and low lignin content, which can not only improve pulp yield. But also reduce ash and extract. Bamboo materials have long firber,long diameter etc characteristic.Made bamboo pulp into paper after the unit area of fiber interweaving more times,paper strength is better. Therefore,bamboo pulp performance is close to wood.stronger than straw.Wheat straw.bagasse and other gramineous plants.

3.Bamboo fiber with high fiber strength

Bamboo cellulose not only has renewable,degradable,good biocompatibility,strong hydrophilicity,excellent mechanical properties and heat resistance etc charactistics.Some scholars conducted tensile test on 12 kinds of bamboo fibers and found that their elastic modulus and tensile strength were both higher than thoseof wood fibers from artificial fast-growing forests.The results show that the tensile modulus and strength of moso bamboo fibers were higher than those of the other three fibers.

4.Bamboo ash and extract content is higher

Compared with wood, the content of ash(about 1.0%) and 1% NAOH extract(about 30.0%) in bamboo higher. Which will produce more impurtities in the pulpling process,which is not conducive to the sewage and wastewater treatment of pulp and paper industry. And will increase machine investment cost.

Bamboo pulp papermaking technology

Since bamboo successfully realized industrial development and utilization,there have been many new technology,new processes,new products of bamboo processing. Thus make the bamboo improving the utilization value.The development of mechanized pulping technology in China has broken through the traditional manual modeand is tranforming to industrialization and industrial production mode. At present. Popular bamboo pulp production technology includes mechanical method.chemical method and chemical mechanical method. China bamboo pulp was mainly processed by chemical method,about have 70%. Chemical mechanical method is less, less than 30%. The production of bamboo pulp by mechanical method is limited to the experimental stage and no large-scale industrialization has reported.

1.Mechanical pulping way

Mechanical pulping is the mechanical grinding of bamboo into fiber,without adding chemical agents, this way advantages of low pollution, high pulp yield,simple process and so on. Under the situation of pollution control and shortage of wood pulp has been paid more and more attention.

Although mechanical pulping method has the advantage of high pulping yeild and low pollution.it is widely used in the pulp and paper industry of coniferous wood such as picea,but due to the high content of lignin, ash and 1% Naoh extract in the chemical composition of bamboo,the pulp quality is poor, and it is difficult to meet the quality requirements of commercical paper.The industrial application is rarely seen,mostly in the stafe of scientific research and technical exploration.

2.Chemical pulp process

Chemical pulpping is bamboo pulp made by sulfate or sulfite process.Bamboo pulp was prepared by screening,washing,dehydration,cooking,causticization,filtration,countercurrent washing,closed screening,oxygen delignfication,bleaching and other process.The cheminal pulping processes can protect the fiber and improve the pulp yield. Obtain the pulp with good quality,clean and soft,easy to bleach,can be used to produce high-grade writing paper and printing paper.

Due to the removal of a large amount of lignin,ash and various extracts in the process of chemical pulping, the pulping yield of bamboo is low,generally 45%-55%.

3. Chemical mechanical pulping process

Chemical machanical pulping based on bamboo pulp for raw materials,which combine chemical pulping process and mechanical pulping process some characteristic as bamboo raw material way. Chemical pulping process include semi-chemical method,chemical machanical method and chemical thermal grinding machine method.

For bamboo pulping and paper making,, the pulping yield of chemical mechanical pulping,generally arrived to 72%-75%.Chemical mechanical pulping method this way produce pulping quality higher than mechanical pulping method. Can be satifies normal products production requirement. At the same time,the cost of alkali recovery and sewage treatment is also between chemical pulping and mechanical pulping.

Bamboo pulp paper equipment

The molding section equipment of bamboo pulp and papermaking production line is basically the same as that of wood pulp production line. The biggest difference of bamboo pulp and papermaking equipment lies in the section for preparing materials such as slicing,washing and cooking.

Because bamboo has a hollow structure,slicing equipment is different from wood. Commonly used bamboo slicing equipment mainly includes roller-type bamboo cutting machine,disk-type bamboo cutting machine and drum chipper. Roller type bamboo cutter and disk type bamboo cutter have higher working efficiency, but the quality of bamboo chips processed(bamboo shape) is not as good as that of drum type chipper. Users can be choose the appropriate slicing equipment according to the use of bamboo pulp and production cost. For small and medium-sized bamboo pulp mills(Capacity<10 ton).Domestic bamboo slicing equipment can meet the needs of production; For large bamboo pulp factory(Capacity≥10tons), Can be choose international advanced large slicing equipment can be used.

Bamboo washing equipment is used to remove impurities, and a variety of patented products have been reported in China. Generally,vacuum pulp washing machine,pressure pulp washing machine and belt type washing machine used. Medium and large enterprises can use new two-roll replacement pressing pulp washing machine or strong dehydration pulp washing machine.

Bamboo slice cooking equipment is used for bamboo slice softening and chemical separation. Small and medium-sized enterprises use vertical digester or horizontal tube continuous digester. Large enterprises can use Camille continuous digester with diffusion washing to improce production efficiency,pulp yield will be improved correspondingly,but it will increase one-time investment cost.

The potential and development direction of bamboo pulp paper in China

1.Bamboo pulp paper has great potential

According to investigation of bamboo resources in China and analysis of the applicability of bamboo itself in papermaking,strongly support develop bamboo pulping industry. Not only can remit the Chinese paper industry wood material shortage.It is also an effective way to change the raw material structure of paper industry,can reduce the dependence on imported wood chips.Some famous scholars have analyzed that the production cost per unit mass of bamboo pulp is about 30% lower than that of pine,spruce,eucalyptus,etc., and the quality of bamboo pulp similar wood pulp.

2. Forest paper integration is an important development direction

Due to the advantages of rapid growth and reproduction of bamboo, strengthening the cultivation of special bamboo forest and establishing bamboo pulp production base integrating forest and paper will become a direction for the sustainable development of China’s pulp and paper industry, reducing the dependence on wood chips and pulp imports, and developing national industry.

3.Tufted bamboo pulping has great development potential

In the current bamboo processing industry, more than 90% of bamboo (nanbamboo) as raw materials, mainly used in the production of household goods and structural materials products. And bamboo pulp paper is basically to bamboo (nanbamboo), bamboo as the main raw materials, forming a raw material competition situation, is not conducive to the sustainable development of the industry. Bamboo pulp and paper industry on the basis of the existing raw materials bamboo, should vigorously develop a variety of bamboo raw materials utilization, make full use of the low price of bamboo, bamboo, bamboo, bamboo bamboo pulp and paper, improve the vitality of market competition.

Normal life, need to use kitchen paper towel clean oil stains. What are the functions and characteristics of kitchen paper towels?

1. Clean and hygienic

Kitchen paper towel is a disposable tissue that avoids bacteria that can build up over time, and it’s on par with rags when it comes to removing stains.

2. Water stain removal

Because the absorbent capacity of kitchen paper is very strong, just wipe the second time with kitchen paper water stains will be gone. And the kitchen paper is not as easy to break as the general paper towels, you can wipe where you want to wipe where, will not drop slag.

3. Strong water absorption

Kitchen paper towel is very absorbent, the most obvious thing in use is to absorb water from food. No matter what kind of food uses kitchen paper to absorb water, we can clearly see that its absorption effect is very good, and absorption speed is also very fast. Put the water into the pot, so there will be no oil spatter.

4. Strong oil absorption

In addition to water absorption, it also absorbs oil well. You can use it to suck the excess oil out of the frying pan so that we can eat it healthier. And the requirements of the kitchen paper is very strict, is not to add fluorescent agents, so you can rest assured that it and food contact. In addition, it can also be used to wipe the tableware with oil stains, wiped tableware will be very convenient to clean.
