IHydroxypropylmethylcellulose (HPMC) isithako esibalulekileyo nesisetyenziswa kwizinto ezininzi ezisetyenziswa kumashishini amaninzi kuquka noluhlu lwe-plaster.I-HPMC yi-ether ye-cellulose ephuma kwi-cellulose kwaye i-nonionic, i-polymer enyibilikayo emanzini.Isetyenziswa ngokuqhelekileyo njenge-thickener, stabilizer kunye ne-emulsifier kwiimarike ezimanzi nezomileyo.Kwishishini le-gypsum, i-HPMC isetyenziswa njenge-dispersant kunye ne-thickener.Eli nqaku lichaza iinzuzo zokusebenzisa i-HPMC kwimveliso yegypsum.
I-Gypsum sisimbiwa sendalo esiqhelekileyo esisetyenziswa kushishino lokwakha ukuvelisa isamente kunye negypsum.Ukuze kwenziwe iimveliso zegypsum, igypsum kufuneka iqale ilungiswe ibe ngumgubo.Inkqubo yokwenza i-gypsum powder ibandakanya ukutyumza kunye nokugaya i-mineral, emva koko ifudumale kumaqondo aphezulu okushisa ukususa amanzi amaninzi.Isiphumo somgubo owomileyo sixutywa namanzi ukwenza intlama okanye i-slurry.
Enye yezona zinto zibalulekileyo ze-HPMC kushishino lwegypsum kukukwazi ukusasazeka.Kwiimveliso ze-gypsum, i-HPMC isebenza njenge-dispersant, iqhekeza i-clumps yamaqhekeza kunye nokuqinisekisa ukusabalalisa kwabo ngokufanayo kulo lonke i-slurry.Oku kubangela intlama egudileyo, ehambelanayo nekulula ukusebenza ngayo.
Ukongeza ekubeni dispersant, HPMC kwakhona a thickener.Inceda ukwandisa i-viscosity ye-gypsum slurry, okwenza kube lula ukulawula nokusebenzisa.Oku kubaluleke kakhulu kwiimveliso ezifuna ukuqina okuthe kratya, njengekhompawundi edibeneyo okanye i-plaster.
Enye inzuzo ebalulekileyo ye-HPMC kushishino lwegypsum kukuphucula ukusebenza kwayo.Ukongeza i-HPMC kwi-gypsum slurries yenza ukuba imveliso isasazeke lula kwaye isebenze ixesha elide.Oku kuthetha ukuba iikontraka kunye nabantu ngabanye banexesha elingakumbi lokusebenza kwimveliso ngaphambi kokuba ibekwe.
I-HPMC ikwaphucula umgangatho kunye nokuqina kwemveliso yokugqibela.Ngokusebenza njenge-dispersant, i-HPMC iqinisekisa ukuba amasuntswana e-gypsum asasazwa ngokulinganayo kuyo yonke imveliso.Oku kwenza ukuba imveliso ibe yinto ehlala ixesha elide, ihambelana kwaye iyancipha ukukrazula kunye nokuphuka.
I-HPMC sisithako esivumelana nokusingqongileyo.Ayinatyhefu, iyabola kwaye ayibangeli ungcoliseko lomoya.Oku kuyenza ibe lolona khetho lubalaseleyo kumashishini axhalabileyo malunga nempembelelo yokusingqongileyo yeemveliso zawo.
I-HPMC sisithako esibalulekileyo kusapho lwegypsum kunye neenzuzo ezininzi.Ukukwazi kwayo ukusabalalisa, ukujiya, ukuphucula inkqubo kunye nokuphela komgangatho wemveliso yenze ukuba ibe yinxalenye ebalulekileyo yoshishino.Ubungane bayo bokusingqongileyo bukwayinzuzo ephawulekayo kwihlabathi apho amashishini amaninzi ajonge ukunciphisa impembelelo yawo yokusingqongileyo.
ukuququmbela
IHydroxypropylmethylcellulose (HPMC) sisithako esibalulekileyo kuluhlu lwe-plaster.Ukukwazi kwayo ukusabalalisa, ukujiya, ukuphucula ukuqhutyelwa phambili kunye nokuphela komgangatho wemveliso yenze ukuba ibe yinxalenye ebalulekileyo yoshishino.Ngaphaya koko, ubuhlobo bayo bokusingqongileyo buluncedo olukhulu kwihlabathi apho amashishini amaninzi afuna ukunciphisa ifuthe lawo lokusingqongileyo.Lilonke, i-HPMC lolona khetho lubalaseleyo kulo naliphi na ishishini elijonge ukuphucula umgangatho weemveliso zabo ngelixa besazi ifuthe labo lokusingqongileyo.
