Hydroxypropyl methyl cellulose (HPMC) yog ib qho cellulose sib xyaw ether ntau yam uas nws cov zis, ntau npaum li cas thiab qhov zoo tau nce sai hauv xyoo tas los no.Non-ionic cellulose sib xyaw ether ua los ntawm lwm cov txheej txheem.
HPMC muaj zoo dispersing, emulsifying, thickening, cohesive, dej-retaining thiab cov pos hniav-retaining zog.Nws yog soluble hauv dej, thiab tseem tuaj yeem yaj hauv ethanol thiab acetone hauv qab 70%.HPMC nrog cov qauv tshwj xeeb kuj tuaj yeem ncaj qha yaj hauv ethanol.HPMC tuaj yeem siv dav hauv cov txheej txheem zaj duab xis, kev tso tawm tus neeg sawv cev thiab khi rau kev npaj tshuaj, thiab tseem tuaj yeem siv dav hauv petrochemicals, cov ntaub ntawv hauv tsev, ceramics, textiles, khoom noj khoom haus, tshuaj txhua hnub los ntawm kev siv nws cov thickening, dispersing, emulsifying thiab film-forming. khoom., hluavtaws cob, tshuaj, pleev xim thiab electronics thiab lwm yam kev lag luam.
Cov txheej txheem tsim khoom ntawm HPMC tuaj yeem muab faib ua ob pawg: cov txheej txheem roj theem thiab cov txheej txheem ua kua theem.Tam sim no, cov teb chaws tsim kho xws li Europe, Tebchaws Asmeskas thiab Nyij Pooj tau siv cov txheej txheem roj-theem ntau dua, siv cov ntaub ntawv ntoo ua cov khoom siv raw (cov paj rwb yog siv los tsim cov khoom muaj viscosity), alkalization thiab etherification yog ua los ntawm tib cov tshuaj tiv thaiv. cov khoom siv, thiab cov tshuaj tiv thaiv tseem ceeb yog cov tshuaj tiv thaiv kab rov tav.Lub hwj muaj lub hauv paus kab rov tav stirring ncej thiab ib sab rotating ya riam tshwj xeeb uas tsim los rau zus tau tej cov cellulose ether, uas yuav tau txais ib tug zoo mixing nyhuv.
Cov kws tshuaj ntsuam xyuas kev lag luam los ntawm Xinsijie tau hais tias nrog kev loj hlob tsis tu ncua ntawm kev lag luam thiab kev txhim kho txuas ntxiv ntawm lub neej zoo ntawm cov neeg, qhov kev thov rau hydroxypropyl methylcellulose hauv Suav lag luam tau nce ntxiv.Tau ntev, kuv lub teb chaws txoj kev lag luam hydroxypropyl methylcellulose xav tau yog tsom rau hauv kev tsim kho thiab txheej txheej.Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam hauv qab, qhov kev thov rau hydroxypropyl methylcellulose hauv cov zaub mov thiab chaw muag tshuaj tau pib nthuav dav sai.Nyob rau hauv lub neej yav tom ntej, kev tsim kho, khoom noj khoom haus thiab kev lag luam tshuaj yuav yog ib qho tseem ceeb tsav tsheb rau kev loj hlob ntawm kuv lub teb chaws txoj kev lag luam hydroxypropyl methylcellulose.
