HPMC Kuba extrusion

I-HPMC, okanye i-hydroxypropyl methylcellulose, i-polymer eyaziwayo esetyenziswa kwizicelo ezininzi, kuquka i-extrusion.I-Extrusion yinkqubo ebandakanya ukubunjwa kwezinto ngokuyinyanzelela ngokufa okanye uthotho lweefa ukuze zenze imilo ethile okanye iprofayili.

Kwi-extrusion, i-HPMC isetyenziswa rhoqo njenge-binder kunye ne-rheology modifier.Inokukunceda ukuphucula iimpawu zokuhamba kwezinto ezikhutshiweyo, okwenza kube lula ukusebenza kunye nokuvelisa imveliso efanayo.HPMC kwakhona lubricant elungileyo, nto leyo enokunceda ukunciphisa ukukhuhlane kwaye banxibe izixhobo ezisetyenziswa kwinkqubo extrusion.

Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kwi-extrusion kukukwazi ukulawula i-viscosity yezinto ezikhutshiweyo.Oku kubaluleke ngakumbi xa usebenza ngezinto eziphezulu ze-viscosity ezinokuba nzima ukuqhubekeka.Ngokudibanisa i-HPMC kwizinto eziphathekayo, inokucuthwa kwaye yenziwe ukuba isebenze ngakumbi, ivumela ukubunjwa okuchanekileyo kunye nolawulo olungcono lomgangatho.

Enye inzuzo yokusebenzisa i-HPMC kwi-extrusion kukukwazi ukuphucula amandla kunye nokuqina kwemveliso yokugqibela.I-HPMC inokusebenza njenge-arhente yokuqinisa, inceda ukuqinisa izinto ezikhutshiweyo kunye nokunciphisa umngcipheko wokuqhekeka okanye ukuphuka.Inokuphucula ukuchaswa kwezinto kumswakama kunye nezinye izinto zokusingqongileyo, okwenza kube yinto ehlala ixesha elide kwaye ihlala ixesha elide.

HPMC kwakhona ukhetho elungileyo izicelo extrusion kuba biocompatible kwaye non-ityhefu.Oku kuyenza ilungele ukusetyenziswa kuluhlu olubanzi lwamashishini, kubandakanywa ukutya kunye namayeza, apho ukhuseleko kunye nokucoceka kubaluleke kakhulu.

Ukongeza kwiinzuzo zayo kwi-extrusion, i-HPMC isetyenziswa ngokubanzi kwezinye iindawo zokuvelisa kunye nokwakha.Idla ngokusetyenziswa xa kusenziwa izinto zokugquma, izinto zokuncamathelisa, izinto zokutywina, kwanasekwenziweni kweeseramikhi kunye nemixube.Ukuguquguquka kwayo kunye nokulula kokusetyenziswa kwenza kube lukhetho oludumileyo kuluhlu olubanzi lwezicelo.

Ngokubanzi, i-HPMC sisixhobo esixabisekileyo kubavelisi ababandakanyekayo kwinkqubo ye-extrusion.Ukukwazi kwayo ukuphucula iipropati zokuhamba, amandla, kunye nokuqina kwezinto ezikhutshiweyo kwenza kube yinto efanelekileyo yokhetho olubanzi lwezicelo.Ngokusebenzisa kwayo i-biocompatibility kunye ne-non-toxicity, ikwayindlela ekhuselekileyo nethembekileyo yokusetyenziswa kumashishini okutya kunye namayeza.
