Sida mid ka mid ah isku-darka ether-ka cellulose-ka muhiimka ah ee hoobiyeyaasha budada qalalan, hydroxypropyl methylcellulose waxay leedahay hawlo badan oo hoobiye ah. Doorka ugu muhiimsan ee hydroxypropyl methylcellulose ee hoobiye sibidhka waa haynta biyaha iyo dhumucdooda. Intaa waxaa dheer, iyada oo ay ugu wacan tahay isdhexgalka nidaamka sibidhka, waxay sidoo kale ka ciyaari kartaa door kaalmeed si ay u xoojiso hawada, dib u dhigista, iyo hagaajinta xoogga curaarta. saamayn.
Waxqabadka ugu muhiimsan ee hydroxypropyl methylcellulose ee hoobiye waa haynta biyaha. Sida isku-darka ether-ka cellulose ee hoobiye, hydroxypropyl methylcellulose waxaa loo isticmaali karaa ku dhawaad dhammaan badeecooyinka hoobiyeyaasha, badiyaa sababtoo ah xajinta biyaha. Guud ahaan, haynta biyaha ee hydroxypropyl methylcellulose waxay la xiriirtaa viscosity, heerka beddelka iyo cabbirka walxaha.
Hydroxypropyl methylcellulose waxaa loo isticmaalaa dhumuc ahaan, saameynteeda dhumucduna waxay la xiriirtaa heerka beddelka, cabbirka walxaha, viscosity iyo heerka wax ka beddelka hydroxypropyl methylcellulose. Guud ahaan marka la eego, heerka sare ee beddelka iyo viscosity ee ether cellulose, iyo qayb ka yar, ayaa aad u cad saamaynta dhumucdiisuna.
Hydroxypropyl methylcellulose, soo bandhigida kooxaha methoxy waxay yaraynaysaa tamarta dusha sare ee xalalka aqueous ee ka kooban hydroxypropyl methylcellulose, sidaa darteed hydroxypropyl methylcellulose waxay leedahay saameyn hawo-mareen ah oo ku saabsan hoobiye sibidhka. Ku soo bandhig goobooyin hawo sax ah oo ku jira hoobiye, sababtoo ah "saameynta kubbadda" ee xumbooyinka hawada
Waxqabadka dhismaha ee hoobiye ayaa la wanaajiyey, isla mar ahaantaana, soo bandhigida xumbo hawada waxay kordhisaa heerka wax soo saarka hoobiye. Dabcan, qadarka hawo-mareenka ayaa u baahan in la xakameeyo. Hawo aad u badan ayaa saameyn xun ku yeelan doonta xoogga hoobiye.
Hydroxypropyl methylcellulose waxay dib u dhigi doontaa habka dejinta ee sibidhka, taas oo hoos u dhigi doonta habka iyo adkeynta habka sibidhka, iyo sii dheeraynta wakhtiga furitaanka hoobiye si waafaqsan, laakiin saamayntani uma fiicna hoobiye gobollada qabow.
Sida walaxda silsiladda dheer ee polymer, hydroxypropyl methylcellulose waxay hagaajin kartaa waxqabadka isku-xidhka ee substrate ka dib markii lagu daro nidaamka sibidhka iyada oo la raacayo habka si buuxda loo ilaalinayo qoyaanka slurry.
Marka la soo koobo, waxqabadkaHPMCHoobiyeyaasha inta badan waxaa ka mid ah: ceyrinta biyaha, dhumucdooda, kordhinta waqtiga dejinta, kicinta hawada iyo hagaajinta xoogga cufan, iwm.
