Xaddi cayiman oo hydroxypropyl methylcellulose ether ah ayaa biyaha ku haya hoobiyaha muddo ku filan si kor loogu qaado fuuq-celinta joogtada ah ee sibidhka loona hagaajiyo isku-xidhka u dhexeeya hoobiyaha iyo substrate-ka.
Saamaynta Cabbirka Walxaha iyo Waqtiga Isku-darka ee Hydroxypropyl Methyl Cellulose Ether ee Haysashada Biyaha
Awoodda kaydinta biyaha ee hoobiyaha waxaa inta badan xakameeya wakhtiga milmida, cellulose-ka khafiifka ahina si dhakhso ah ayuu u milmaa, awoodda haysashada biyahana si dhakhso ah ayay u sii kordheysaa. Dhismaha farsamada, sababtoo ah xaddidaadda waqtiga, doorashada cellulose waa inay noqotaa budo khafiif ah. Si gacanta loogu sameeyo, budo khafiif ah ayaa shaqayn doonta.
Saamaynta Heerka Etherification iyo Heerkulka Hydroxypropyl Methyl Cellulose Ether ee Haysashada Biyaha
Milmida iyo heerkulka hydroxypropyl methylcellulose ee biyaha waxay ku xiran tahay heerka etherification-ka. Marka heerkulka dibadda uu kordho, haynta biyuhu way yaraataa; heerka etherification-ka oo sarreeya, ayaa sii fiicnaanaya haynta biyaha ee cellulose ether.
Saamaynta hydroxypropyl methylcellulose ether ee ku aaddan isku dheelitirka iyo iska caabbinta simbiriirixan ee hoobiyaha
Joogtaynta iyo hantida ka hortagga simbiriirixan ee hoobiyaha ayaa ah tilmaamayaal aad muhiim u ah, labadaba dhismaha lakabka qaro weyn iyo dhejiska foornada waxay u baahan yihiin isku-dheellitirnaan ku habboon iyo hanti ka hortag simbiriirixan.
Habka tijaabada joogtada ah, oo lagu go'aamiyay heerka JG/J70-2009
Joogtaynta iyo iska caabbinta simbiriirixan waxaa inta badan lagu ogaadaa viscosity-ga iyo cabbirka walxaha ee hydroxypropyl methylcellulose. Marka uu kordho viscosity-ga iyo waxa ku jira, joogteynta hoobiyaha ayaa kordha; marka uu yar yahay cabbirka walxaha, ayuu sii kordhayaa joogteynta hore ee hoobiyaha cusub ee isku dhafan.
Saamaynta Hydroxypropyl Methyl Cellulose ee Gelinta Hawada ee Madaafiicda
Maadaama lagu daray hydroxypropyl methylcellulose hoormoonka, xaddi gaar ah oo xumbo hawo oo yaryar, isku mid ah iyo kuwa deggan ayaa lagu soo daraa hormoonka cusub ee isku dhafan. Sababtoo ah saameynta kubbadda, hormoonku wuxuu leeyahay awood dhismo oo wanaagsan wuxuuna yareeyaa yaraanta iyo wareegga hormoonka. Wuu dildilaacaa, wuxuuna kordhiyaa heerka wax soo saarka hormoonka. Cellulose wuxuu leeyahay shaqo hawo gelin ah. Markaad ku darayso cellulose, tixgeli qiyaasta, viscosity (viscosity aad u sarreeya wuxuu saameyn doonaa shaqada), iyo sifooyinka hawo gelinta. Dooro cellulose hormoonada kala duwan.
