Qadar cayiman oo ah ether hydroxypropyl methylcellulose ayaa biyaha ku haysa hoobiye wakhti ku filan si kor loogu qaado fuuq-celinta joogtada ah ee sibidhka iyo hagaajinta isku dhejinta u dhexeeya hoobiye iyo substrate-ka.
Saamaynta Cabbirka Walxaha iyo Wakhtiga isku darka Hydroxypropyl Methyl Cellulose Ether ee Haysashada Biyaha
Awooda haynta biyaha ee hoobiye waxaa inta badan gacanta ku haya wakhtiga kala dirida, cellulose-ka aadka u fiicanna si dhakhso ah ayuu u milmaanaa, iyo sida ugu dhakhsaha badan awoodda haynta biyuhu waa.Dhismaha makaanikada, sababtoo ah waqtiga xaddidan, doorashada cellulose waa inay noqotaa budo khafiif ah.Ku dhejinta gacanta, budo ganaax ah ayaa sameyn doonta.
Saamaynta Darajada Etherification iyo Heerkulka Hydroxypropyl Methyl Cellulose Ether ee Haysashada Biyaha
Solubility iyo heerkulka hydroxypropyl methylcellulose ee biyaha waxay ku xiran tahay heerka etherification.Marka heerkulka dibadda uu kordho, haynta biyaha ayaa hoos u dhacda;heerka sare ee etherification, ayaa si fiican u haynta biyaha ee eter cellulose.
Saamaynta hydroxypropyl methylcellulose ether ee joogtaynta iyo iska caabbinta sibidhka ee hoobiye
Isku-dhafka iyo hantida ka-hortagga ee hoobiye ayaa ah tilmaamayaal aad muhiim u ah, labadaba dhismaha lakabka dhumucdiisuna waxay u baahan yihiin joogtayn ku habboon iyo hantida ka-hortagga silitaanka.
Habka tijaabada joogtada ah, oo lagu go'aamiyay si waafaqsan heerka JG/J70-2009
Joogteynta iyo iska caabbinta silbashada waxaa inta badan lagu gartaa viscosity iyo cabbirka walxaha hydroxypropyl methylcellulose.Marka la kordhiyo viscosity iyo content, joogtaynta hoobiye ayaa kordha;Sida ugu fiican ee cabbirka walxaha, ayaa sare u kacaya joogteynta bilowga ah ee hoobiye cusub oo la isku daray.degdeg ah.
Saamaynta Hydroxypropyl Methyl Cellulose ee Ku-gelinta Hawada Hoobiyaha
Sababo la xiriira ku darida hydroxypropyl methylcellulose ee hoobiye, xaddi gaar ah oo yaryar, labis ah iyo goobooyin hawo deggan ayaa la gelinayaa hoobiye cusub oo isku qasan.Saamaynta kubbadda awgeed, hoobiyegu wuxuu leeyahay dhismo wanaagsan wuxuuna yareeyaa yaraanshaha iyo dildilaaca hoobiyeyaasha.Dildilaaca, oo kordhiya heerka wax soo saarka hoobiye.Cellulose waxay leedahay shaqo hawo-mareen ah.Markaad ku darto cellulose, tixgeli qiyaasta, viscosity (muoog aad u sarreeya ayaa saameynaya karti-shaqsiyeedka), iyo guryaha-hawo-mareenka.Dooro cellulose hoobiyeyaal kala duwan.
