Cov phiaj xwm dav dav rau kev siv cov txiaj ntsig ntawm HPMC yog raws li hauv qab no:
Lub zog ua kom lub zog ntawm cov tshuaj tiv thaiv nyob rau hauv cov kauj ruam no yog txo, thaum lub fluidity ntawm cov tshuaj tiv thaiv sib tov yog txhim kho, thiab qhov tsis xws luag ntawm cov tawm los ntawm methylation cov tshuaj tiv thaiv nyob rau hauv thawj txheej txheem yog daws. Hauv qhov piv txwv, los ntawm kev tshawb fawb thiab kev siv cov khoom theem reactor, hydroxypropyl methylcellulose phthalate hais yog tsim.
Ib qho yog los ua tus pab cuam muaj txiaj ntsig zoo, txhim kho cov tshuaj tiv thaiv tawm los, thiab tswj cov tiam ntawm cov tshuaj tiv thaiv sab,
Thib ob, raws li cov khoom siv hluav taws xob, HPMC yog siv los ua cov khoom siv hluav taws xob zoo los txhim kho cov purity ntawm reactants thiab cov tshuaj tiv thaiv tawm los, kom cov tshuaj tiv thaiv tuaj yeem nce mus txog 98%. Kev siv tus nqi ntawm cov khoom siv raw yog nce mus rau 95% los ntawm kev siv hydroxypropyl methyl cellulose ua tus neeg sawv cev pabcuam, uas lav qhov kev npaj ntawm hydroxypropyl methyl cellulose phthalate thiab tiv thaiv agglomeration ntawm cov khoom hauv cov txheej txheem tom qab kho.
Qhov thib peb yog los daws qhov teeb meem ntawm qhov tsis tshua muaj txiaj ntsig ntawm cov txheej txheem qub. Ib tus neeg sawv cev kev sim yog kom txo tau cov khoom siv raw cov paj rwb fiber ntau los ntawm 1.05t / t ntawm cov txheej txheem qub rau 0.94t / t thaum lub sij hawm phthalic acid cov tshuaj tiv thaiv. residual acetic acid hnyav tuaj yeem raug tshem tawm. Cov txiaj ntsig ntawm cov kauj ruam no tau nce mus rau 95%.
Youngcel HPMC/MHEC Nws yog dav siv los ua Tus Neeg Sawv Cev Pabcuam rau Pobzeb Adhesive, Cement Plaster, Qhuav mix mortar, Phab ntsa putty, Txheej, Detergent thiab lwm yam.Thiab peb tuaj yeem muab koj tus nqi qis tshaj thiab zoo tshaj plaws.
Peb cov khoom yog nrov nyob rau hauv Egypt, Russia, South Africa, Middle East, qaib ntxhw, Nyab Laj, Fabkis, Ltalis, Singapore, Bangladesh, Indonesia, South America thiab hais txog. Ua tsaug ua ntej thiab txais tos hu rau.
