Yintoni i-hydroxypropyl methyl cellulose?
IHydroxypropyl methyl cellulose (HPMC), eyaziwa nangokuthi i-hydroxypropyl methylcellulose, i-cellulose hydroxypropyl methyl ether, i-cellulose, i-2-hydroxypropylmethyl ether, i-PROPYLENE GLYCOL ETHER YE-METHYLCELLULOSE, i-CAS No. I-HPMC inokohlulwa ibe ibakala lokwakha, ibakala lokutya kunye nebakala lamayeza ngokokusetyenziswa kwayo. Isetyenziswa ngokubanzi kulwakhiwo, ukutya, amayeza kunye nezithambiso, iikhemikhali zemihla ngemihla kunye namanye amashishini.
Ziziphi ukusetyenziswa kweHPMC?
Ishishini lokwakha

Ungawubona njani umgangatho we-hydroxypropyl methyl cellulose (HPMC)?
1. I-Chromaticity: nangona ingakwazi ukuchonga ngokuthe ngqo ukuba i-HPMC ilula ukuyisebenzisa, kwaye ukuba i-ejenti emhlophe yongezwa kwimveliso, umgangatho wayo uya kuchaphazeleka. Nangona kunjalo, iimveliso ezikumgangatho ophezulu sele ziza kuthengwa.
2. Ukulunga: I-HPMC ine-80 meshes kunye ne-100 meshes ngokubanzi, kunye ne-120 meshes ingaphantsi. Uninzi lwe-HPMC lune-80 meshes. Ngokuqhelekileyo, ukona okulaleleyo kubhetele.
3. Ukuhanjiswa kokukhanya: beka i-hydroxypropyl methyl cellulose (HPMC) emanzini ukwenza i-colloid ebonakalayo, kwaye emva koko ubone ukukhanya kwayo. Okukhona ukuhanjiswa kokukhanya, kungcono, kubonisa ukuba akukho nto inganyibilikiyo kuyo.
4. Umxhuzulane okhethekileyo: Okukhona unzima ngakumbi umxhuzulane othile, kokukhona ungcono. Umlinganiselo ubalulekile, ngokubanzi ngenxa yokuba umxholo we-hydroxypropyl uphezulu. Ukuba umxholo we-hydroxypropyl uphezulu, ukugcinwa kwamanzi kungcono.
I-Hydroxypropyl methyl cellulose izinzile kwi-acids kunye neziseko, kwaye isisombululo saso samanzi sizinzile kakhulu kuluhlu lwe-pH = 2 ~ 12. Singumvelisi oqeqeshiweyo. Ukuba ufuna le mveliso, ungaqhagamshelana nathi. Kuphelele apho kukwabelana nge-HPMC kulo mba. Ndiyathemba ukuba inokukunceda uqonde i-HPMC.
