Iziphumo zokuphucula kwe-hydroxypropyl methyl seluplose kwizinto ezisekwe kwizixhobo ezisekwe

Hydroxypropyl methyl seluplose

Ukuseta uvavanyo lwexesha

Ixesha lokuseta ikhonkrithi linxulumene ikakhulu kwixesha lesamente, ifuthe elihlanganisiweyo alifani, ke ukumiswa komxube ngenxa yokuphononongwa kwe-HPMC ye-HPMC ye-HPMC ngexesha lokuma, i-quatio yesamente kunye Ubuyi-getya-yesanti yodaka kufuneka ilungiswe.

I-HPMC yisakhiwo se-macromolecule, kunye neqela le-hydroxyl kwiqela elisebenzayo, elinokwenza iibhondi ze-hydrogen ngokuxuba iimolekyuli zamanzi kunye nokunyusa i-viscosity yamanzi okuxuba. I-HPMC ixesha elide lemolekyuli iya kutsala omnye, ukuze i-HPMC Molekrus idrerwine kunye nenye yokwenza isakhiwo senethiwekhi, isamente, ukudibanisa amanzi asongelweyo. Kungenxa yokuba i-HPMC ichaza i-Netlegement yenethiwekhi efana nefilimu ethambileyo kunye neflethi yesamente, iya kuthi ithintele ukukhutshwa komswakama ebrwenswa, kwaye inciphise umgangatho we-qumed.

Uvavanyo lokutsala amanzi

Into ephuma emanzini yodaka iyafana neyekhonkrithi, eya kuthi ibangele ukwanda komda wesamente, kunye nokwenza ubuqhetseba okuqala kweplastiki, kwaye amandla omphezulu obuthathaka. Ukusuka ekuvavanyeni, kunokubonwa ukuba xa isixa semali yokudibanisa ngaphezulu kwe-0.5%, akukho nto ivuza amanzi. Kungenxa yokuba i-HPMC ixutywe kubukho bobumbano, i-HPMC inolungeko lwefilimu kunye nenethiwekhi, kunye ne-adsorption ye-chain kunye nokudibanisa ukubhalwa kwamanzi, ukuqinisekisa ukwakhiwa kwesitali somzimba. Emva kongeza i-HPMC e-TARD kwakhona, kuya kwenziwa amaqamsa amaninzi amancinci azimeleyo. Ezi gubble ziya kuhanjiswa ngokulinganayo eluphango kwaye kuthintele ifakwe i-Agggate. I-HPMC Intsebenzo yobugcisa yezinto ezisisiseko zesamente inefuthe elihle, elidla ngokulungiselela ukungcungcutheka olomileyo, udaka lwePolymer olusekwe kwizinto ezinobungozi, ukuze ifungelwe iplastiki, iplastiki.
