Ngenxa yezinto ezifana nobushushu bomoya, ukufuma, uxinzelelo lomoya, kunye nesantya somoya, izinga lokuguquguquka komswakama kwiimveliso ezisekwe kwi-gypsum liya kuchaphazeleka.
Ngoko ke nokuba ikwi-gypsum-based leveling mortar, i-caulk, i-putty, okanye i-gypsum-based self-leveling, i-hydroxypropyl methylcellulose ether (HPMC) idlala indima ebalulekileyo.
Ukugcinwa kwamanzi kwe-BAOSHUIXINGHPMC
I-hydroxypropyl methylcellulose (HPMC) egqwesileyo inokusombulula ngempumelelo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu.
Amaqela ayo e-methoxy kunye ne-hydroxypropoxy asasazwa ngokulinganayo kwi-cellulose molecular chain, enokuphucula amandla ee-athomu ze-oksijini kwi-hydroxyl kunye ne-ether bonds ukuba zidibene namanzi ukuze zenze ii-hydrogen bonds, zenze amanzi akhululeke abe ngamanzi abotshelelweyo, ngaloo ndlela ilawula ngempumelelo ukufuma kwamanzi okubangelwa yimozulu ephezulu ukuze kufezekiswe ukugcinwa kwamanzi okuphezulu.
Ukwakhiwa kweSHIGONGXINGHPMC
Iimveliso ze-cellulose ether ezikhethwe ngokuchanekileyo zinokungena ngokukhawuleza kwiimveliso ezahlukeneyo ze-gypsum ngaphandle kokudibana, kwaye azinampembelelo imbi kwi-porosity yeemveliso ze-gypsum ezicociweyo, ngaloo ndlela ziqinisekisa ukusebenza kokuphefumla kweemveliso ze-gypsum.
Inefuthe elithile lokulibazisa kodwa ayichaphazeli ukukhula kweekristale zegypsum; iqinisekisa amandla okubopha kwezinto kumphezulu osisiseko ngokunamathela okumanzi okufanelekileyo, iphucula kakhulu ukusebenza kolwakhiwo lweemveliso zegypsum, kwaye kulula ukusasazeka ngaphandle kwezixhobo zokuncamathela.
Ukutyeba kwe-RUNHUAXINGHPMC
I-hydroxypropyl methylcellulose ekumgangatho ophezulu ingasasazwa ngokulinganayo nangokufanelekileyo kwi-samente mortar kunye neemveliso ezisekwe kwi-gypsum, kwaye igqume zonke iinxalenye eziqinileyo, kwaye yenze ifilimu yokumanzisa, kwaye umswakama kwisiseko uya kunyibilika kancinci kancinci kwixesha elide. Ikhulula, kwaye idlule kwi-hydration reaction kunye nezinto ze-inorganic gelling, ngaloo ndlela iqinisekisa amandla okubopha kunye namandla okucinezela ezinto.
