Isticmaalayaal badan ayaa si dhif ah fiiro gaar ah u leh dhibaatada heerkulka jel ee hydroxypropyl methylcellulose.Maalmahan, hydroxypropyl methylcellulose guud ahaan waxaa lagu kala soocaa iyadoo loo eegayo 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 jelka ee hydroxypropyl methylcellulose.
Maaddada methyl acid waxay si toos ah ula xiriirtaa heerka ester-samaynta ee ester cellulose, iyo waxa ku jira methyl acid waxaa lagu hagaajiyaa si loo xakameeyo qaabeynta, heerkulka falcelinta iyo waqtiga falcelinta.Isla mar ahaantaana, heerka xalka etherka wuxuu saameeyaa nuxurka hydroxyethyl ama hydroxyapatite.Sidaa darteed, ether-ka cellulose ee heerkulka caadiga ah ee jelku wuu yarayn doonaa.Habka wax-soo-saarkani waa inuu noqdaa mid la taaban karo, markaa halkii uu ka ahaan lahaa heerarka hoose ee methoxides, ether-ka cellulose wuxuu noqon doonaa mid wax yar ka sarreeya qiimaha.
Heerkulka jel waxaa lagu go'aamiyay methoxide iyo hydroxyproazepam oo leh hydroxyproxin.Saddex kooxood oo keliya ayaa lagu beddeli karaa cellulose.Soo hel heerkulka saxda ah, ilaali qoyaanka, oo go'aami qaabka saxarka.Heerkulka jelku waa barta muhiimka ah ee isticmaalka etherka cellulose.Marka heerkulka deegaanku uu dhaafo heerkulka jelka, etherka cellulose ayaa laga sii deyn doonaa biyaha.Heerkulka saxarka suuqa ayaa inta badan ah inuu daboolo baahiyaha xalka deegaanka (marka laga reebo xaalado gaar ah).Waxaa la rumeysan yahay in marka la isticmaalayo xalka, ma aha lagama maarmaan in si gaar ah loo eego tilmaamayaasha waxqabadka marka la isticmaalayo jel.Dabcan, soo saaraha ether cellulose waa in ay tixgeliyaan tilmaame this.
