Dhibaatooyinka caadiga ah ee Hydroxypropyl Methyl Cellulose
1. Waa maxay codsiga ugu muhiimsan ee hydroxypropyl methylcellulose (HPMC)?HPMC waxaa si weyn loogu isticmaalaa qalabka dhismaha, dahaarka, xabagta synthetic, ceramics, daawada, cuntada, dunta, beeraha, qurxinta, tubaakada iyo warshadaha kale.HPMC waxa loo qaybin karaa darajada dhismaha, heerka cuntada iyo...Akhri wax dheeraad ah -
Waa maxay faraqa u dhexeeya HPMC iyo MC
MC waa methyl cellulose, kaas oo lagu helo in lagu daweeyo suuf la safeeyey alkal, iyadoo la isticmaalayo methyl chloride wakiilka etherifying, iyo samaynta cellulose ether iyada oo taxane falcelin ah.Guud ahaan, heerka beddelka waa 1.6 ~ 2.0, iyo solubility sidoo kale waa ka duwan yahay heerar kala duwan ...Akhri wax dheeraad ah -
Waxyaalaha Saameeya Waxsoosaarka Viscosity ee HPMC
1. Xakamaynta Viscosity High-viscosity hydroxypropyl methylcellulose ma soo saari karto cellulose aad u sarreeya oo kaliya iyada oo la faaruqinayo oo lagu beddelayo nitrogen.Si kastaba ha ahaatee, haddii qalabka cabbiraadda ogsijiinta lagu rakibi karo kiliyaha, wax-soo-saarka viscosity-ga waxaa lagu xakameyn karaa si macmal ah.2. Isticmaalka...Akhri wax dheeraad ah -
Tababarka tignoolajiyada dhumucda rinjiga ku salaysan ee ugu kooban
1. Qeexida iyo shaqada dhumucyada Waxyaabaha lagu daro oo si weyn u kordhin kara viscosity ee rinjiga biyaha ku salaysan waxaa loo yaqaan dhumucyada.Dhumucdiisuna waxay door muhiim ah ka ciyaaraan wax soo saarka, kaydinta iyo dhismaha dahaarka.Shaqada ugu weyn ee dhumudhiyuhu waa inuu kordhiyo viscosity o...Akhri wax dheeraad ah -

Codsiga HPMC ee qalabka dhismaha
Hydroxypropyl methylcellulose (HPMC) waa eter cellulose aan-ionic ahayn oo laga sameeyay maadada polymer-ka dabiiciga ah ee cellulose iyada oo loo marayo taxane kiimiko ah.Waa budo cad oo aan ur lahayn, dhadhamin iyo aan sun ahayn oo ku barara biyo qabow si ay u noqdaan xal kolloidal ah oo cad ama yar.Wuxuu leeyahay pro...Akhri wax dheeraad ah -
Habka kala soocida iyo kala dirida HPMC
1.Classification: HPMC waxa loo qaybin karaa nooca degdega ah iyo nooca kulul-dhalaalaya.Alaabooyinka nooca degdega ah ayaa si degdeg ah ugu firdhiya biyo qabow oo ku baaba'aan biyaha.Waqtigaan, dareeruhu ma laha viscosity, sababtoo ah HPMC kaliya ayaa lagu kala firdhiyey biyaha mana lahan milan dhab ah.Qiyaastii 2 daqiiqo ka dib, waxaa...Akhri wax dheeraad ah -
