I-Hydroxy Propyl Methyl Cellulose (HPMC)– Umgubo oMhlophe woMgangatho woRhwebo

Into Intshayelelo

Le yi-Hydroxy Propyl Methyl Cellulose ecocekileyo ephezulu (HPMC) kuhlobo lomgubo ocolekileyo omhlophe. Iveliswa ukusetyenziswa kwezorhwebo, ngokukodwa kunyango lwamanzi kunye nokuveliswa kwephepha. Imveliso iyanyibilika ngokukhawuleza kumanzi abandayo kwaye iphuhlisa icace, inkonzo eshinyeneyo. Ayinyibiliki emanzini ashushu kodwa idumba kuqala phambi kokuba ifume ngokupheleleyo njengoko iphola.

Imfihlo ibandakanya

Ugcino lwamanzi olugqwesileyo: I-HPMC igcina amanzi kakuhle, enceda ukulawula izinga lokumisa kwiingubo zephepha kunye ne-sludge conditioning.
Ubungqingqwa obuzinzileyo: Igcina ubukhulu obuqinileyo kulo lonke uluhlu olubanzi lwe-pH (3– 11), ukuyenza ithembeke kwiingxaki ezahlukeneyo zenkqubo.
Ubume be-non-ionic: Kuba ilala endlini, isebenza kakuhle nezinye iikhemikhali ezahlukeneyo ngaphandle kokubangela ukusabela okungafunekiyo.
I-gelation ye-thermal: Inketho ijika ibe yijeli xa ishushu kwaye ibuyele kulwelo xa ipholile– luncedo kumanyathelo okuphatha iinkcukacha.

Usetyenziso
