HPMC-jauhe
HPMC-jauhe puhdistetaan puuvillasta alkalisoinnin jälkeen. Se käyttää propyleenioksidia ja metyylikloridia eetteröintiaineina ei-ionisen selluloosa-sekoitetun eetterin tuottamiseksi reaktiosarjan jälkeen. Milestone Industrial Co. Ltd: llä on 20 vuoden kokemus HPMC-jauheen valmistuksesta ammattilaboratorioilla ja työpajoilla sekä tehokas huoltopalvelutakuu. Se voi mukauttaa HPMC-jauhetta eri viskositeeteilla asiakkaiden tarpeiden mukaan.

HPMC-jauhe
HPMC-jauhe is refined from cotton after alkalization. It uses propylene oxide and methyl chloride as etherification agents to produce non-ionic cellulose mixed ether after a series of reactions. Milestone Industrial Co. Ltd. has 20 years of experience in the production of HPMC powder, with professional laboratories and workshops, and efficient after-sales service guarantee. It can customize HPMC-jauhe with different viscosities according to customer needs.

HPMC-jauhe product features:
1. HPMC-jauhe is easily soluble in cold water, hot water will dissolve. Its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also much better than methyl cellulose.
2. The viscosity of HPMC-jauhe is related to the molecular weight. When the molecular weight is large, the viscosity is high. Temperature will also affect its viscosity, as the temperature increases, the viscosity decreases. But the high viscosity of HPMC-jauhe is lower than that of methyl cellulose.
3. The water retention capacity of HPMC-jauhe depends on its added amount, viscosity, etc.; the water retention rate is higher than that of methyl cellulose.
4. HPMC-jauhe is stable to acid and alkali, and its aqueous solution is stable in the range of pH = 2-12. Caustic soda and lime water have little effect on its performance, but alkali can accelerate its dissolution and slightly increase its viscosity. HPMC-jauhe is stable to ordinary salt, but when the concentration of the salt solution is high, the viscosity of the HPMC-jauhe solution tends to increase.
5. HPMC-jauhe can be mixed with water-soluble polymer to form a uniform and high viscosity solution. Such as polyvinyl alcohol, lake water powder ether, vegetable glue, etc.
6. HPMC-jauhe has better enzyme resistance than methyl cellulose, and the possibility of enzymatic degradation of its solution is lower than that of methyl cellulose.
7. The adhesion between HPMC-jauhe and mortar structure is higher than that of methyl cellulose.
HPMC-jauhe produced by MST is used in the fields of water-resistant putty powder, putty paste, tempered putty, paint glue and thermal insulation mortar.
