Yintoni i-HPMC ye-Gypsim Plaster?

I-HYDROXYLLL Methylcelceltulose (HPMC) idlala indima ebalulekileyo ekwandiseni intsebenzo kunye neepropathi ze-gypsim. Le nto iguquguqukayo isebenza imisebenzi eyahlukeneyo, igalelo ekuqhubekeni, ukubambelela, ukugcinwa kwamanzi, kunye nomgangatho opheleleyo wodaka.

Isakhiwo sekhemikhali kunye neepropathi:
I-HPMC yeyosapho laseLiclulose TOO, ethathwe kwi-sellyulose, i-polymer yemvelo ifumaneka kwiindonga zeseli ezityalo. Ngokuguqula iikhemikhali, amaqela e-Hydroxyl kunye namaqela e-methyl azaziswa kwi-selsulose ngasemva, okukhokelela ekuqulunqweni kwe-HPMC. Olu hlengahlengiso lubonisa iipropathi ezizodwa kwi-HPMC, kubandakanya ukuzolula kwamanzi, ukungcwaba i-thermal, amandla okwenza ifilimu, kunye neempawu zokongeza ifilimu, kunye neempawu zokonga.

Inkqubo yeMveliso:
Ukuveliswa kwe-HPMC kubandakanya amanyathelo aliqela. Ekuqaleni, i-seluplose ikhutshwe kwimithombo yezityalo efana ne-pulp okanye umqhaphu. Emva koko, le seluplose iphantsi kwe-ether, apho i-hydroxypropy kunye namaqela e-methyl iqhotyoshelwe kwi-Hydroxyl (---). Inqanaba lokufakwa endaweni yala maqela linokulawulwa ngexesha lokuSynthesi, ukuphembelela iipropathi zemveliso yokugqibela ye-HPMC. Okokugqibela, i-HPMC ephumelelweyo iyahlanjululwa, yomile, kwaye iqhubekisiwe kumabakala ahlukeneyo efanelekileyo kwizicelo ezahlukeneyo.

Isicelo kwi-Gypsim Plaster:
I-HPMC isetyenziswa ngokubanzi njengesongezelelo kwi-Gyppsum Plations ngenxa yeepropathi zawo ezahlukeneyo. Xa ifakwe kwi-Plaster Hlanganisa, i-HPMC isebenza njenge-Rheology Modifier, ilawula i-vifotity kunye neempawu zokuhamba kwe-slicry. Oku kuphucula ukusebenza kodaka, ukuvumela ukusetyenziswa ngokulula kunye nokugungqa ukugqiba.

Ngapha koko, i-HPMC isebenza njengearhente yokugcina amanzi, inciphisa ilahleko yamanzi ngexesha lokubeka kunye namanqanaba okomisa. Olu hlaselo lude lukhuthaza unyango olufanelekileyo lodaka, olukhokelela ekuphuculeni amandla kunye nokuqina kwemveliso egqityiweyo. Ukongeza, i-HPMC iphucula i-ambethension ye-Plasters kwiMihlaba yeMihlaba, ukuqinisekisa ukuba i-bonds engcono kunye nokunciphisa umngcipheko wokulibazisa okanye ukuqhekeka kwexesha.

Izibonelelo ze-HPMC kwi-Gypsim Plaster:
Ukuphuculwa kokuphuculwa: I-HPMC idlulisela ukungangqinelani okukuko ukudibanisa i-sface, yenze kube lula ukusasazeka kwaye iphumelele xa kusenziwa isicelo.
Ukugcinwa kwamanzi okusebenzayo: ngokunciphisa ukuvela kwamanzi, i-HPMC inyusa inkqubo ye-hydration, ekhokelela kunyango olungcono kunye namandla ngokubanzi.
I-Adhesion engaphezulu: i-HPMC ikhuthaza ububi obunamandla phakathi kodaka kunye nokuthintela umhlaba, ukuthintela ukuqinisekisa ukuthembeka kwexesha elide.
Ixesha elilawulwayo
Ukunganyangeki: I-HPMC inegalelo ekuhlambulyeni komxube uxube, ukunciphisa ukwenzeka kwee-shrinkage kwaye kuphuculwe ukugqiba komphezulu.

I-HydroxyPOpyl Methylcelcellulose (HPMC) yiyobisi exabisekileyo ye-Gypppum Plation, inika uluhlu olubanzi lwezibonelelo ezifaka isandla kwinkqubo yokuphuculwa kwentsebenzo kunye nomgangatho. Indima yayo njenge-Rheology Modifier, iarhente yokugcina amanzi, kunye nokukhuthaza i-adhesion yenza ukuba ingabaluleki kumzi-mveliso wokwakha, apho i-Gypsim Prece isetyenziselwa ukugqiba izicelo. Ngokuqonda iipropathi zekhemikhali kunye nokusebenza kwe-HPMC, abavelisi kunye nabafaki-zicelo banokwanda ukwenza iimfuno ezithile zokwenza umsebenzi kwaye bafezekise iziphumo eziphezulu.
