Yintoni i-hydroxypropyl methyl cellulose HPMC?

HPMC hydroxypropyl methyl celluloseumenzi wefektri othengisa ngaphandle
Loluphi usetyenziso oluphambili lwe-HPMC?
I-HPMC inokohlulwa ibe: ibakala lokwakha, ibakala lokutya kunye nebakala lezonyango ngokusetyenziswa.
I-HPMC isetyenziswa ngokubanzi kwizinto zokwakha, iingubo, ii-resin zokwenziwa, iiseramikhi, amayeza, ukutya, amalaphu, ezolimo, izithambiso, icuba kunye namanye amashishini.
Okwangoku, ininzi yebakala lokwakhiwa kwasekhaya, kwibakala lokwakha, i-putty powder dosage inkulu, malunga ne-90% isetyenziselwa ukwenza i-putty powder, enye isetyenziselwa ukwenza udaka lwesamente kunye neglue.

Zeziphi ezona mathiriyeli ekrwada eziphambili ze-HPMC?
Izixhobo eziphambili zeHPMC: umqhaphu osulungekileyo, ikloromethane, ipropylene oxide. Ezinye izinto eziluhlaza zi, i-tablet alkali, i-asidi, i-toluene, i-isopropanol kunye nokunye.

- I-HPMC yahlulwe yaba ziindidi ezininzi, yintoni umahluko kusetyenziso?
HPMC inokohlulwa ibe uhlobo ngoko nangoko kunye nobushushu enyibilikayo.

Iimveliso ezikhawulezayo, emanzini abandayo zihlakazekile ngokukhawuleza, zanyamalala emanzini, ngeli xesha i-liquid ayinayo i-viscosity, kuba i-HPMC ihlakazekile nje emanzini, akukho ukuchithwa kwangempela. Malunga nemizuzu emi-2, i-viscosity yolwelo ikhula kancinci, yenze i-colloid ebonakalayo ebonakalayo. Uluhlu olubanzi lwesicelo, kwi-putty powder kunye nodaka, kunye neglue emanzi kunye nepeyinti, ingasetyenziswa, akukho taboo.

Iimveliso ezishushu ezinyibilikayo, kumanzi abandayo, zinokusasazwa ngokukhawuleza emanzini ashushu, zinyamalale emanzini ashushu, xa ubushushu buhla kwiqondo elithile lobushushu, i-viscosity ibonakala kancinci, de kube yi-colloid ebonakalayo ebonakalayo. Inokusetyenziswa kuphela kwi-putty powder kunye nodaka, kwi-glue ye-liquid kunye nepeyinti, kuya kubakho i-phenomenon yeqela, ayinakusetyenziswa.

Ziziphi iimpawu eziphambili zezobugcisaHPMC?
Umxholo weHydroxypropyl kunye ne-viscosity, abaninzi abasebenzisi banenkxalabo ngezi zikhombisi zimbini.

Umxholo weHydroxypropyl uphezulu, ukugcinwa kwamanzi ngokuqhelekileyo kungcono.

I-Viscosity, ukugcinwa kwamanzi, isalamane (kodwa ayikho ngokupheleleyo) nayo ingcono, kunye ne-viscosity, ngodaka lwesamente olungcono ukusebenzisa ezinye.

Ingakanani i-viscosity efanelekileyo kwi-HPMC?
Eyona ndima ibalulekileyo ye-HPMC kukugcina amanzi, kulandele ukujiya.
Iputty powder ngokuqhelekileyo 100000 cps ingaba. Ngethuba nje ukugcinwa kwamanzi kulungile, i-viscosity iphantsi (70,000-80000), inokwenzeka, ngokuqinisekileyo, i-viscosity inkulu, ukugcinwa kwamanzi okuhambelanayo kubhetele, xa i-viscosity ingaphezulu kwe-100,000, i-viscosity ine-viscosity. impembelelo encinci ekugcinweni kwamanzi.
Imfuno kwi-MORTAR inde kakhulu, UFUNA NGOKUBANZI I-150 AMAWAKA ukuze ulungele ukusebenzisa.
Ukusetyenziswa kweglue: kufuneka iimveliso ezikhawulezayo, i-viscosity ephezulu.
