I-HPMC, okanye iHydroxypropyl Methyl Cellulose, sisixhobo sokwakha esiguquguqukayo nesiyimfuneko esikhule ngokuthandwa kwiminyaka yakutshanje.Njengoko i-cellulose derivative, i-HPMC inezicelo ezivela kwizinto zokuthambisa ukuya kwi-adhesives, kwaye ngokugqithiseleyo, ifumene indlela yayo kwishishini lokwakha njenge-thickener, i-adhesive, i-colloid ekhuselayo, i-emulsifier kunye ne-stabilizer.
I-HPMC yomgangatho wokwakha ikumgangatho ophezulu, i-polymer enyibilikayo emanzini esetyenziswa kwiimveliso ezahlukeneyo zesamente ezibandakanya ukuncamatheliswa kweethayile, udaka, iiplaster, iigrouts, kunye neenkqubo zangaphandle zokugquma kunye nokugqiba (EIFS).Iipropathi zayo eziguquguqukayo ziyenza ibe sisisombululo esigqibeleleyo kuzo zombini iiprojekthi zokwakha ezintsha kunye nohlengahlengiso, njengoko inyusa iipropathi zebhondi kunye nokudibanisa izinto ezininzi ezahlukeneyo.
Enye yeenzuzo eziphambili ze-HPMC yimpawu zayo zokugcina amanzi.Oku kuthetha ukuba kunokunceda ukunciphisa umthamo wamanzi afunekayo kwiimveliso ezisekelwe kwisamente ngaphandle kokuncama iimpawu okanye ukusebenza komxube.Ngokugcina umswakama, kuthintela umxube ukuba umile, unceda ukuphucula ukunamathela kunye namandla emveliso yokugqibela.
Ukongezelela, i-HPMC isebenza njenge-colloid ekhuselayo, inceda ukunciphisa umngcipheko wokwahlula, ukuqhekeka kunye nokunciphisa izinto ze-cementitious.Oku kwenza ukuba ibe yinto efanelekileyo yokongeza kwiimveliso ezivezwe kwiimeko zemozulu ezinzima okanye zifuna ukumelana noxinzelelo oluphezulu.
Ukongeza kwezi zakhiwo zokuphucula ukusebenza, i-HPMC yamkelwa ngokubanzi njengento ezinzileyo kakhulu.Yenziwe kwimithombo evuselelekayo, i-biodegradable kwaye ayinayo ityhefu, eyenza ibe lolona khetho lufanelekileyo kubakhi abaqaphela indalo kunye neenkampani zokwakha.
Njengobungqina bokuguquguquka kwayo, i-HPMC ikwasetyenziswa kwimveliso yeemveliso ezisekelwe kwi-gypsum ezifana ne-stucco kunye neekhompawundi ezidibeneyo.Kule meko, i-HPMC inceda ukuphucula ukusebenza kunye nokuhambelana komxube, ngelixa ukwandisa amandla okudibanisa phakathi kwe-stucco kunye ne-substrate.
Ibakala lokwakha i-HPMC ifumaneka kwiindidi ze-viscosity kunye nobukhulu bamasuntswana, okuvumela izinto ukuba zilungelelaniswe neemfuno ezithile zemveliso.Oku kuyenza ibe yimathiriyeli eguquguqukayo kakhulu enokuthi isetyenziswe kwiintlobo ezahlukeneyo zezicelo kunye nokusingqongileyo.
Ukuqukumbela, i-HPMC iyinto ebalulekileyo kushishino lokwakha kwaye imiba yayo emihle mininzi.Ngogcino lwamanzi olugqwesileyo, i-colloid ekhuselayo kunye neendawo ezizinzileyo, yinto eyongezelelweyo kunye nexabiso elixabisekileyo kuyo nayiphi na imveliso yokwakha.Iphucula ukusebenza, inciphisa inkunkuma kwaye ifanelekile kubakhi abaqaphela indalo kunye neenkampani zokwakha.Ukusetyenziswa kwe-HPMC kuqaqambisa ikamva loshishino lokwakha.
