Heerkulka gel HPMC

Isticmaalayaal badan ayaa dhif u ah inay fiiro gaar ah u yeeshaan dhibaatada hydroxypropyl methyl cellulose heerkulka jel ee HPMC.Maalmahan, hydroxypropyl methyl cellulose HPMC guud ahaan waxaa lagu kala saaraa viscosity, laakiin qaar ka mid ah bay'ada gaarka ah iyo warshadaha gaarka ah, kaliya viscosity ee alaabta ayaa ka muuqda.Kuma filna, kuwan soo socda ayaa si kooban u soo bandhigaya heerkulka jel ee hydroxypropyl methylcellulose HPMC.

Waxyaabaha ku jira kooxda methoxy waxay si toos ah ula xiriirtaa heerka etherification ee etherka cellulose.Waxa ku jira kooxda methoxy waxaa lagu hagaajin karaa iyada oo la xakameynayo caanaha, heerkulka falcelinta iyo waqtiga falcelinta.Isla mar ahaantaana, heerka etherification wuxuu saameeyaa heerka beddelka hydroxyethyl ama hydroxypropyl.Sidaa darteed, haynta biyaha ee ether cellulose leh heerkulka jel sare guud ahaan waa wax yar ka sii daran.Habkan wax soo saarka waa in la sahamiyaa, sidaas darteed maaha sababtoo ah maadada methoxy waa mid hooseeya, qiimaha etherka cellulose waa hooseeyaa, liddi ku ah, qiimaha ayaa noqon doona mid sare.

QUALICELL's hydroxypropyl methyl cellulose HPMC hydroxypropyl content waa 25%.Heerkulka jelku waa barta muhiimka ah ee isticmaalka etherka cellulose.Marka heerkulka deegaanku uu dhaafo heerkulka jelka, ether-ka cellulose-ka ayaa ka soo daadanaya biyaha oo lumin doona haynta biyaha.Heerkulka ether-ka ee Qualicell's cellulose waa 65 darajo, kaas oo asal ahaan dabooli kara baahida hoobiye iyo bey'ada isticmaalka (marka laga reebo deegaanno gaar ah).Haddii aad iibsato QualiCell HPMC, fadlan horay u ogeysii haddii aad shuruudo gaar ah leedahay.
