Product Description The English abbreviation of hydroxypropyl methylcellulose is HPMC, which is a non-ionic cellulose ether with a molecular formula of C56H108O30. CAS 9004-65- 3, odorless, tasteless, white powder. Hydroxypropyl methylcellulose (HPMC) absorbs moisture after drying but is stable. The solution is stable at pH 3-11. As the temperature increases, the viscosity of the solution decreases. Heating-cooling can reversibly transform HPMC from a solution state to a gel state. According to different grades and concentrations, the gel temperature is 50～90℃. HPMC water solution has anti- enzyme effect and maintains good viscosity stability during long-term storage. However, its aqueous solution is susceptible to microbial attack, so preservatives should be added during storage. When HPMC is used as a thickening agent in eye drops, benzalkonium chloride is usually added as a preservative.

Product Description HPMC is made from mature polymer cellulose through a series of chemical processing. It is used in various applications in the construction, food, pharmaceutical and personal care industries. Depending on the application, it can be used as a thickener, adhesive, film-forming agent, water-retaining agent, suspending agent and lubricant. HPMC Features HPMC use for Water Retention: maximized water content in slurry. Anti-sagging: when spreading a thicker coat corrugation can be avoided. Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation, HPMC can increase the mortar volume. Exterior Insulation and Finish System ( EIFS ) Improved adhesion. Good wetting ability for EPS board and substrate. Reduced air entrancement and water uptake

Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Hydroxypropyl Methylcellulose Description No primer or curing required thus there is considerable cost saving Protects expensive paints from moisture and flaking Highly durable and water resistant Prevents the growth of algae and fungus Economical and long lasting Dissolution Method(HPMC) 1. Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Goon stirring until it cools down and becomes clear 2. Another way is by heating the amount of 1/3 or 2/3 water to above 85℃, add the cellulose to obtain hot slurry, then add the remaining cold water and keep stirring, the mixture is obtained when the slurry cools to about 20 ℃

Yihang activated carbon pellets for waste gas treatment is a very good adsorbent, it is the use of charcoal, various fruit shells and high quality coal as raw materials, through physical and chemical methods of raw materials for crushing, sieving, catalyst activation, rinsing, drying and screening a series of processes and manufacturing. Activated carbon pellets has the dual characteristics of physical adsorption and chemical adsorption, can selectively adsorb a variety of substances in the gas phase and liquid phase, in order to achieve decolorization and purification, disinfection and deodorization and decontamination. Activated carbon adsorption method is to use activated carbon as a physical adsorbent to concentrate the harmful substances produced in the process of electrostatic spraying on the solid surface, so that the waste gas can be purified and treated. The adsorption process is a physical process that occurs at the interface between solid and gas phases. Yihang activated carbon pellets is characterized by large specific surface area, developed pore structure, reasonable pore distribution, strong adsorption capacity, uniform particle distribution and high wear resistance. Used for purifying chemical raw gas, chemical synthesis gas, pharmaceutical industry gas, beverage carbon dioxide gas, hydrogen, nitrogen, hydrogen chloride, ethane, cracking gas, inert gas, etc.

Product Description The granular activated carbon used for solvent recovery is made from high quality anthracite coal as raw material and refined by physical activation method. It is black granular, non-toxic and tasteless, with developed pores, reasonable distribution of three types of pores and strong adsorption capacity. In a wide concentration range, GAC has stronger adsorption capacity for most of the organic solvent vapor. It is widely used in organic solvent recovery, such as benzene, ether, xylene, ethanol, acetone, gasoline, chloroform, carbon tetrachloride and so on. Granular activated carbon has the characteristics of high strength, fast adsorption speed, high adsorption capacity, large specific surface area, developed pore structure, moderate pore size, etc. The solvent recovery process using granular activated carbon is to pass the mixed gas containing organic solvent vapor into the reactor filled with activated carbon. The solvent vapor is adsorbed on the granular activated carbon by the strong selective adsorption capacity of granular activated carbon, and the purified air removing the solvent vapor flows out from the other end of the reactor. After the granular activated carbon is saturated, it stops adsorption and then regenerates. When it is regenerated, water vapor is generally used to remove the solvent adsorbed on the activated carbon, and then the desorption vapor is condensed and the organic solvent is recovered. The regenerated granular activated carbon is dried and cooled for recycling.
