Jiangsu HPMC hydroxypropyl methylcellulose factory. [Jilong building materials] chemical industry 1. Polymerization of vinyl chloride and vinylidene: as suspension stabilizer and dispersant during polymerization, it can be used together with polyvinyl alcohol (PVA) hydroxypropyl cellulose (HPC), and can control particle shape and distribution. 2. Adhesive: as the adhesive of wallpaper, it can be used together with vinyl acetate emulsion paint instead of starch. 3. Pesticide: it can be added to insecticide and herbicide to improve the adhesion effect during spraying. 4. Latex: emulsion stabilizer for improving asphalt latex, thickener for SBR latex. 5. Binder: used as a molding binder for pencils and crayons.
For the heated room, the higher temperature is conducive to the construction of thermal insulation mortar powder, but attention should be paid to the problems caused by excessive drying and water loss on the working surface. The sand used for bricklaying shall be carefully screened without ice. According to the construction, when the appropriate antifreeze mixed mortar is filled according to the actual needs, the temperature of the water shall not exceed 80 ℃, so as to adjust it with the used ground, rather than the cement construction in the open air, and antifreeze shall be done well. If the putty powder is applied on rainy days, dry cloth shall be used to wipe the water vapor on the wall to keep the wall as dry as possible. At the same time, the drying time of putty shall be extended as much as possible according to the actual weather conditions, generally 2-3 days, but it is also necessary to extend the drying time of the wall properly after the completion of brushing. Generally speaking, the normal interval is about 2 hours. Rainy days can be extended according to weather conditions. Building rubber powder is made of cold water as dispersion medium without heating. The cold water above 1 ℃ can be quickly and fully dissolved into mucus, which is a new environmental protection and energy saving product. At the same time, the building rubber powder can quickly form a three-dimensional interwoven network in the external insulation premixed mortar, improve the adhesion and constructability of mortar putty to the base material, form a flexible membrane on the coating surface, effectively prevent the coating from cracking, block the penetration and absorption of water, and extend the service life of putty coating.
1. The packaging bag of sodium cellulose has enough strength, and has two layers, the outer layer is a three in one composite packaging, the inner layer is a film bag, which meets the requirements of moisture-proof and not damaged. 2. The inner and outer seal of the packing bag shall be separately tied. 3. The net weight of each bag is 25kg. The research, development, production and operation of cellulose sodium industry provide excellent cellulose sodium series products and perfect cellulose sodium application scheme for ceramics, building materials, coatings, textile printing and dyeing, oil drilling and other industries, creating more value for consumers. With the slowdown of China's economic development, the consumption frequency of cellulose sodium tends to decline, which is mainly affected by the upstream raw materials. Sodium cellulose is an anionic high member complex lost after the reaction of natural cellulose and alkaloids plus monochloroacetic acid. The secondary by-products are sodium chloride and sodium glycolate. The raw material of sodium cellulose is mainly the refined cotton brewed from cotton linter. The output of its own grass cotton has tended to be stable. In addition, the environmental protection achievements in recent years have restricted the output of refined cotton to be stable in a hurry, with a slight decline trend.
3. What are the main raw materials of HPMC? A: the main raw materials of HPMC: refined cotton, methyl chloride, propylene oxide, and other raw materials, such as flake alkali, acid, toluene, isopropanol, etc. 4. What is the main role of HPMC in the application of putty powder? Is there any chemical change? Answer: hydroxypropylmethylcellulose in putty powder, its thickening, water retention and construction three functions. Thickening: cellulose can be thickened to play a role of suspension, keeping the solution uniform up and down, and anti sagging. Water retention: make putty powder dry slowly, assist the reaction of grey calcium under the action of water. Construction: cellulose has lubricating effect, which can make putty powder have good workability. HPMC is not involved in any chemical reaction, but only plays an auxiliary role. Putty powder is a chemical reaction to add water to the wall. Take the putty powder off the wall, grind it into powder, and then use it again. It will not work, because a new substance (calcium carbonate) has been formed. The main components of calcium ash powder are: the mixture of Ca (OH) 2, Cao and a small amount of CaCO3, CaO + H2O = Ca (OH) 2-Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O. Under the action of CO2 in water and air, calcium ash generates calcium carbonate, while HPMC only keeps water and aids the better reaction of calcium ash, which does not participate in any reaction. 5. Hydroxypropyl methylcellulose is a non-ionic cellulose ether, so what is non-ionic? A: Generally speaking, non-ionic is a substance that will not ionize in water. Ionization refers to the process in which the electrolyte is dissociated into free moving charged ions in a specific solvent. For example, sodium chloride (NaCl), a salt eaten every day, dissolves in water to produce sodium ions (Na +) that can move freely with positive charge and chloride ions (CL) with negative charge. In other words, when HPMC is placed in water, it will not dissociate into charged ions, but exists in the form of molecules.
2、 [production method] add and use according to the above preparation data. The mixing time is 20-25 minutes during the mixing process. 3、 Our recommended scheme is based on our experience and foundation of current raw materials and construction application technology for customers' reference. As we can not control the quality of raw materials, production process, actual construction requirements and use environment, our suggestions do not imply any guarantee and commitment to the quality of end products of users! The user is responsible for the adjustment of the formulation system and the final control of the quality according to the actual situation. Application of hydroxypropyl methylcellulose in diatomite mud I. diatomite mud is a kind of indoor decorative wall material with diatomite as the main raw material, which has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire-retardant, self-cleaning of walls, sterilization and deodorization, etc. Diatom mud is a new generation of interior decoration material instead of wallpaper and latex paint because of its health and environmental protection, not very decorative, but also functional. 2、 Hydroxypropyl methylcellulose for diatom mud is a kind of non-ionic cellulose ether, which is made of natural high polymer material cellulose through a series of chemical processing.
