FAQS
Hydroxypropyl methylcellulose (HPMC) macellulose ether anga aine mapoka ehydroxyl pacheni ye cellulose akatsiva methoxy kana hydroxypropyl boka.It inogadzirwa neakakosha etherification yeyakanyanya yakachena donje cellulose pasi pemamiriro ealkaline. Mumakore achangopfuura, HPMC, senge inoshanda musanganiswa, inonyanya kuita basasmukuchengetedza mvura uye kukora muindasitiri yekuvaka uye inoshandiswa zvakanyanya mukatidrymix matope, senge mataira anonamira, grouts, plastering, wall putty, self leveling, insulation dhaka uye nezvimwe.
Kazhinji, yeputty powder, iyo viscosity yeHPMCinokwana pa70,000 kusvika ku80,000. Chinonyanya kutariswa ndechekuita kwayo kwekuchengetedza mvura, nepo kukora mhedzisiro kuri kudiki. Zvedhaka, zvinodiwa zveHPMCdzakakwirira, uye viscosity inoda kutenderedza 150,000, iyo inogona kuve nechokwadi kuti inoshanda zvirinani mudhaka resimende. Zvechokwadi, muputty powder, chero bedzi kushandiswa kwekuchengetedza mvura kweHPMC kwakanaka, kunyange kana viscosity yakaderera (70,000 kusvika 80,000), inogamuchirwa. Zvisinei, mudhaka resimende, inonyanya kunaka kusarudza HPMC ine viscosity yakakura (inopfuura 100,000), nokuti iyo yekuchengetedza mvura inokonzera inonyanya kukosha mumamiriro ezvinhu aya.
Dambudziko rekubvisa putty powder rinonyanya kuenderana nemhando ye calcium hydroxide uye haina zvishoma zvekuita neHPMC. Kana iyo calcium ye calcium hydroxide yakaderera kana chiyero cheCaO uye Ca (OH) 2 isina kukodzera, inogona kuita kuti putty powder iwa. Nezvekukanganisa kweHPMC, inonyanya kuratidzwa mukuita kwayo kwekuchengetedza mvura. Kana iyo HPMC yekuchengetedza mvura ichiita isina kunaka, inogona zvakare kuve nemhedzisiro pakupera kweputty powder.
Zvinodiwa zvekushandiswa kweputty powder zvakaderera. A viscosity ye100,000 yakakwana. Chinokosha ndechekuva nemaitiro akanaka ekuchengetedza mvura. Panyaya yedhaka, izvo zvinodikanwa zvakakwirira uye yakakwirira viscosity inodiwa, uye iyo 150,000 chigadzirwa chine mhedzisiro iri nani.
