Hydroxypropyl methyl cellulose (HPMC) is a cellulose yakasanganiswa ether akasiyana ayo akabuda, dosi uye mhando zvave kuwedzera nekukurumidza mumakore achangopfuura.Non-ionic cellulose yakasanganiswa ether yakagadzirwa nemamwe maitiro.
HPMC ine zvakanaka dispersing, emulsifying, thickening, cohesive, water-retaining and gum-retaining properties.Inonyungudika mumvura, uye inogonawo kunyungudutswa mu ethanol uye acetone pazasi 70%.HPMC ine yakakosha chimiro inogona zvakare kunyungudika zvakananga mu ethanol.HPMC inogona kushandiswa zvakanyanya seyakaputira firimu, inosimudzira kuburitsa mumiririri uye binder yekugadzirira mishonga, uye inogona zvakare kushandiswa zvakanyanya mupetrochemicals, zvekuvakisa, ceramics, machira, chikafu, makemikari ezuva nezuva nekushandisa kukora, kuparadzira, emulsifying uye kugadzira firimu. properties., resin yekugadzira, mushonga, pendi uye zvemagetsi nezvimwe minda.
Iyo nzira yekugadzira yeHPMC inogona kukamurwa kuita mapoka maviri: gasi chikamu nzira uye yemvura chikamu nzira.Parizvino, nyika dzakabudirira dzakadai seEurope, United States neJapan dzinoshandisa mamwe gasi-chikamu muitiro, kushandisa huni pulp seyakabikwa (cotton pulp inoshandiswa kugadzira yakakwirira-viscosity zvigadzirwa), alkalization uye etherification inoitwa nenzira imwecheteyo. midziyo, uye mhinduro huru ndeye horizontal reaction.Iyo kettle ine yepakati yakatwasuka inobvongodza shaft uye nedivi rinotenderera banga rinobhururuka rakagadzirirwa kugadzirwa kwe cellulose ether, iyo inogona kuwana yakanaka yekusanganisa maitiro.
Vanoongorora maindasitiri kubva kuXinsijie vakati nekuenderera mberi kwehupfumi hwenyika uye nekuenderera mberi kwekuvandudzwa kwehupenyu hwevanhu, kudiwa kwehydroxypropyl methylcellulose mumusika weChina kuri kuramba kuchiwedzera.Kwenguva refu, nyika yangu hydroxypropyl methylcellulose kudiwa kwemusika kunonyanya kutariswa muminda yekuvaka uye machira.Nekuenderera mberi kwekusimudzira maindasitiri epasi, kudiwa kwehydroxypropyl methylcellulose muminda yezvekudya nemishonga kwatanga kukura nekukurumidza.Mune ramangwana, maindasitiri ekuvaka, ezvekudya uye emishonga ichave yakakosha kufambisa simba mukukura kwemusika wenyika yangu wehydroxypropyl methylcellulose.
