Pag-aaral sa Cellulose at HPMC sa mga Aplikasyon ng Mga Materyales
HPMC is a non-ionic cellulose ether made from refined cotton after alkalization, using propylene oxide and methyl chloride as etherification agents, through a series of reactions; and MHEC is produced from refined cotton after alkalization treatment, using ethylene oxide and methyl chloride as etherification agents, after a series of reactions, because the storage and use risk factor of ethylene oxide is higher than that of propylene oxide, so The production technology and process requirements of MHEC are higher. There are fewer manufacturers and the price of MHEC is higher than that of HPMC.
