Hydroxypropyl methylcellulosewaxa uu leeyahay dhumuc, xidhidh, kala firdhisa, emulsifying, film samaynta, laalista, adsorbing, gelling, dusha firfircoon, qoyaan-hayntiisa iyo sifooyinka kolloid ilaalinta. Kala duwanaanshaha codsiyadu waa mid aad u ballaaran.
Wanaag
Wanaajinta hydroxypropyl methylcellulose guud ahaan waxay leedahay mesh 80 iyo 100 mesh. Sida ugu fiican ee ganaaxu, sida ugu dhakhsaha badan ee kala diriddu, guud ahaan marka la hadlo, ayaa ka sii wanaagsan. Caadi ahaan, reactors toosan waxay soo saaraan alaabo ka khafiifsan reactors-ka toosan.
Gudbinta
Ku milmi hydroxypropyl methylcellulose (HPMC) biyaha si aad u samayso dareere hufan. Fiiri gudbintiisa iftiinka. Sida weyn ee gudbinta iftiinka, ayaa ka sii wanaagsan, taas oo muujinaysa in ay jiraan waxyaabo aan milmi karin oo ku jira.
saamiga
Cabbirka dhexdhexaadka ah ayaa ka fiican. Haddii culeyska gaarka ah uu aad u weyn yahay ama aad u yar yahay, waxay noqon kartaa natiijada xakamaynta liidata inta lagu jiro habka wax soo saarka.
Dibadda
Hydroxypropyl methylcellulose saafi ah waa muuqaal qalafsan oo leh cufnaanta bulk hooseeya, oo u dhaxaysa 0.3-0.4g/ml; HPMC ee la sinaystay ayaa leh dareere ka wanaagsan oo dareema culeys, taaso iska cad inay ka duwan tahay badeecada dhabta ah muuqaal ahaan. Muuqaalka qaar ka mid ah cellulose-ujeedada gaarka ah ayaa sidoo kale aad uga duwan kuwa tilmaamayaasha caadiga ah, iyo alaabooyin gaar ah ayaa si faahfaahsan loo falanqeeyay.
xal aqueous
Xalka biyaha saafiga ah ee HPMC waa cad yahay, gudbinta iftiinka sare, xajinta biyaha ≥ 90%; Xalka biyaha ee HPMC ee baalaysan waa turbid, iyo heerka haynta biyuhu way adagtahay in la gaadho 70%
BaiDu
Inkasta oo caddaanku aanu go'aamin karin iyo in kaleHPMCWay fududahay in la isticmaalo, iyo haddii walxaha caddeynta lagu daro inta lagu jiro habka wax soo saarka, waxay saameyn doontaa tayada. Si kastaba ha noqotee, badi alaabooyinka wanaagsan waxay leeyihiin caddaan wanaagsan.
