HPMC for Waterproofing Mortars

I-HPMC, okanye i-hydroxypropyl methylcellulose, yinto esetyenziswa ngokuqhelekileyo kwi-additives kwimveliso yodaka lokukhusela amanzi. Izixhobo zokukhusela amanzi zisetyenziselwa ukudala umqobo wokukhusela kwiindawo eziphathekayo, ukuthintela ukungena kwamanzi kunye nokwenza umonakalo.

Omnye weyona misebenzi iphambili ye-HPMC kwiindonga zokungangeni manzi kukusebenza njenge-thickener kunye ne-rheology modifier. Ukongezwa kwe-HPMC kumdaka kuphucula ukusebenza kwayo kunye nokusasazeka, okwenza kube lula ukuyifaka kunye nokusebenza nayo. I-HPMC iphinda iphucule ukuhambelana kunye nokuzinza kodaka, ukunciphisa umngcipheko wokudilika okanye ukudilika ngexesha lokufaka isicelo.

Ukongeza kwiipropathi zayo ezityebileyo, i-HPMC ikwasebenza njenge-binder kunye ne-ejenti yokwenza ifilimu kwiidaka zokuthintela amanzi. Ukongezwa kwe-HPMC kumdaka kuphucula ukunamathela kwayo kwi-substrate, ukudala ibhondi eyomeleleyo kunye neyomelele ngakumbi. I-HPMC iphinda yenza ifilimu ekhuselayo kumphezulu wodaka, onceda ukukhusela kwimozulu kunye nokukhukuliseka.

Enye inzuzo yokusebenzisa i-HPMC kwiindonga zokungangeni manzi kukuba inokunceda ukuphucula ukuxhathisa udaka kumanzi kunye nokufuma. I-HPMC inokubamba amanzi kwidaka, enceda ukuthintela amanzi ukuba angangeni kumphezulu kwaye enze umonakalo. Oku kunokubaluleka ngokukodwa kwiindawo apho kukho umngcipheko omkhulu wokungena kwamanzi, njengamagumbi angaphantsi kunye nezinye izicelo ezingaphantsi komgangatho.

I-HPMC ikwaluncedo kokusingqongileyo. Yipolymer engokwemvelo, ehlaziyiweyo, kunye ne-biodegradable evela kwi-cellulose, eninzi kwizityalo. Ayinatyhefu kwaye ayikhuphi izinto ezinobungozi kwindawo engqongileyo.

Ngokubanzi, ukongezwa kwe-HPMC kwiidaka zokuthintela amanzi kunika inani leenzuzo, kuquka ukuphuculwa kokusebenza, ukunamathela, kunye nokuxhathisa amanzi kunye nokufuma. I-HPMC ikwanceda ukukhusela udaka kwimozulu kunye nokhukuliseko, kwaye inokuphucula ukuqina kwayo ekuhambeni kwexesha. Ikwayinto eyongezelelweyo ehambelana nokusingqongileyo.
