Momwe mungagwiritsire ntchito cellulose ether
Kutha Mwachangu:
1. Pakugwedezeka kosalekeza, HPMC imasungunuka m'madzi ndi zosungunulira zina, monga kusungunuka mofulumira.Njira yoyenera:
(1) Gwiritsani ntchito madzi otentha pamwamba pa 80 ° C kuti muwonjezere pang'onopang'ono mankhwalawa pansi pa kugwedeza kosalekeza.Ma cellulose amamwazikana pang'onopang'ono m'madzi ndipo amakhala slurry wotupa.Sakanizani ndi kuziziritsa mpaka yankho likuwonekera, kutanthauza kuti lasungunuka kwathunthu.
(2) Kutenthetsa pafupifupi theka la madzi ofunikira kufika pamwamba pa 80 ° C, onjezerani mankhwalawa ndi kusonkhezera kosalekeza kuti mupeze slurry, onjezerani madzi ozizira otsalawo, ndikugwedeza mpaka kuwonekera.
2. Gwiritsani ntchito mukatha kuphika phala ngati chakumwa cha mayi:
Choyamba pangani HPMC kukhala mowa wambiri wonga phala (njirayi ndi yofanana ndi yomwe ili pamwamba pa matope amatope).Mukamagwiritsa ntchito, onjezerani madzi ozizira ndikupitiriza kusonkhezera mpaka ziwonekere.
Kuchita kwa cellulose ether mumatope owuma a ufa
Cellulose ether imakhala ndi madzi abwino kwambiri osungira madzi mumatope, omwe amatha kuteteza matope kuti asawume ndi kusweka chifukwa cha kutaya madzi mofulumira, kotero kuti matope amakhala ndi nthawi yayitali yomanga.
Kuchulukana kwa cellulose ether kumatha kuwongolera kusasinthika kwabwino kwa msewu wamatope, kuwongolera kulumikizana kwamatope, kukwaniritsa zotsutsana ndi sag, kuwongolera magwiridwe antchito, ndikuwonjezera kwambiri ntchito yomanga.
Ma cellulose ether amatha kusintha kwambiri kukhuthala konyowa kwa matope onyowa ndikuwonetsetsa kuti matope amadzi amakhala ndi mgwirizano wabwino pamagawo osiyanasiyana.
The kwambiri bwino chomangira mphamvu ya mapadi ether akhoza kuonetsetsa madzi okwanira ngakhale mu malo kutentha mkulu, kotero kuti simenti akhoza mokwanira hydrated, motero kuonetsetsa ubwenzi wabwino wa matope.
Ma cellulose ether ali ndi ntchito ina yopangira mpweya kuti iwonjezere kutulutsa kwamatope.
