HPMC Powder High Quality for Gypsum-manufacture,factory,supplier from China

Cellulose ethers are often used as water-retaining agents in (desulfurized) gypsum mortar. Years of research have shown that,water-retaining agent has a very important influence on the gypsum quality and anti-plastering layer performance of plastering gypsum.

Cellulose ether has a wide range of uses in the building materials industry.Can be used as retarder, water retention agent, thickener and binder.The most important roles of cellulose ether (especially HPMC and HEMC) in cement-based adhesives are water retention and thickening.In addition, due to its interaction with the cement system, it also plays an auxiliary role in entraining air, delayed coagulation and improving tensile bond strength.Structural formula (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OCH2CH(CH3)]OCH3 Specification of non modified products   

Hydroxypropyl methylcellulose (HPMC) and hydroxyethyl methylcellulose (HEMC) are widely used building materials, when applied to gypsum-based plastering, it has the following characteristics:Water Retention: Retains in the mortar, allowing the gypsum to fully set.

HPMC is a white or slightly yellowish powder, which is odorless, tasteless and non-toxic. It can be dissolved in cold water and organic mixed solvents to form a transparent viscous solution. The aqueous solution has surface activity, high transparency, strong stability, and is not affected by pH when dissolved in water. It has thickening and antifreezing effects in shampoo and body wash, and has water retention and good film-forming property for hair and skin.

MELLUTEL-SL400Application in the Self-levelingSelf-leveling mortar is a special dry mixed mortar product with self-leveling and self-compaction function; it is widely used in factories, hospitals, shopping malls, offices and well. Home furnishing and other places. MELLUTEL leveling  cellulose e ther products, after special process control, widely used in various cement and gypsum based leveling Product system.1. Prevent settlement, stratification, segregation, etc., and ensure the flow degree and operating time of self-leveling mortar2.

The hydroxypropyl methyl cellulose ether hpmc is the essential condition for thin bed technology for tile adhesive.Can be used as retarder, water retention agent, thickener and binder.For example, the performance of mortar is very different between natural sand and machine-made sand. Cellulose ether for ordinary dry mixed mortar shall have the following characteristics:Structural formula  (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OCH2CH(CH3)]OCH3 Specification of non modified products          Type      ItemHPMCPD

HEMC are often used as water-retaining agents in (desulfurized) gypsum mortar. Years of research have shown that,water-retaining agent has a very important influence on the gypsum quality and anti-plastering layer performance of plastering gypsum.

HPMC is the proper material for you in case you need to increase the tensile energy of gypsum plaster and different production material.

Cellulose water-retaining agentAt present, the most widely used in the market is hydroxypropyl methyl cellulose, followed by methyl cellulose, and then carboxymethyl cellulose. The comprehensive performance of hydroxypropyl methyl cellulose is better than that of methyl cellulose, and the water retention of the two is much higher than that of carboxymethyl cellulose, but the thickening effect and bonding effect are worse than that of carboxymethyl cellulose.

Compared with the traditional cement mortar, gypsum mortar has the advantages of fire prevention, heat insulation, sound insulation, flame retardant, light weight, humidity adjustment, no hollowing and cracking, etc. In recent years, gypsum mortar has developed rapidly. MELLUTEL HPMC cellulose ether endows gypsum mortar with the following characteristics:Structural formula                                             (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OC

Appearance is White to slightly off-white fibrous or granular powder.

HPS is a kind of ionic hydroxypropyl starch ether, which is produced by a series of chemical and physical reactions with starch as raw material. It is a kind of non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on.  ETON Hydroxypropyl starch ether is a kind of chemical modified starch mainly used as thickener and texturing agent for cement or gypsum based mortar products.

Hydroxypropyl Methyl Cellulose products have the maximum consumption in the area of suspension polymerization of vinyl chloride in China. In the suspension polymerization of vinyl chloride, the dispersed system has a direct impact on the product, PVC resin, and on the quality of its processing and products. Hydroxypropyl Methyl Cellulose helps to improve the thermal stability of resin and control the particle size distribution(in other words, adjust PVC density), and its amount accounts for 0.025% -0.03% of PVC production.

Swells in water and produces a clear to opalescent,viscous colloidal mixture, high transparency, stable performance, HPMC dissolved in water is not affected by pH value.

Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation.
