I-HydroxypropyTelmethylcelcelcelcelcelcebalose (i-HPMC) isetyenziswa ngokubanzi kwishishini lokwakha. Umsebenzi wayo ophambili kukuphucula iipropathi ezisebenzayo zezixhobo ezinje ngodaka kunye nekhonkrithi. Enye yezicelo ze-HPMC yinqanaba lokuzimela nge-gypsim, elinefuthe elibonakalayo kwishishini lokwakha.
I-Plaster yokuziGaba eQhelekileyo ngumgangatho ophezulu osemgangathweni ekulula ukufaka kwaye unokusetyenziswa kwikhonkrithi okanye kwikhonkrithi. Luhlobo oluthandwayo lolwakhiwo lorhwebo kunye nolwakhiwo lokuhlala ngenxa yokusebenza kwayo kunye nokuqina. Owona mceli mngeni ophambili ekuzingazeni isicelo se-PART ukukhulisa ugcina umgangatho kunye nokungaguquguquki kwezinto ezibonakalayo ngexesha lokulungiselela kunye nokufakelwa. Kuyindawo apho i-HPMC idlala khona.
I-Hydroxypropyl Methylcelcelcelose i-tickener ye-swickener eyongezwe kwi-Gyppum yokuzimela ukuze iqinisekiswe ngokusasazwa komxube. Ikwanceda ukulawula i-viscofity kunye nokugcina umgangatho wezinto ezibonakalayo. I-HPMC sisithako esibalulekileyo kwi-Gypsing Gyppum Equngqwizwe njengoko ilinza umxube, ukuqinisekisa ukuba ukwahlulahlulwa kungenzeki kwaye kuphucula amandla aphezulu komxube.
Inkqubo yokwenza isicelo ye-Gypsim ibandakanya ukudibanisa i-gypm kunye ne-HPMC kunye namanzi. Amanzi esebenza njengomphathi we-HPMC, aqinisekisa ukuhambisa kwawo kumxube. I-HPMC yongezwa kumxube kwinqanaba le-1-5% yobunzima owomileyo we-gypsum, kuxhomekeke ekusetyenzisweni okufunekayo nokuphela kwento.
Kukho izibonelelo ezininzi zokongeza i-HPMC ukuya kwi-Plaster yeNkampani. Iyonyusa ukuqina komxholo ngokwandisa amandla kunye nokuchasana namanzi, iikhemikhali kunye ne-abrasion. Ukongeza, i-HPMC inyusa ukuguquguquka kwezinto, ivumela ukuba ikwazi ukuziqhelanisa notshintsho kubushushu kunye nokufuma. Oku kuthintela imizobo, kunciphisa inkunkuma kwaye kuqinisekiswe ubuhle bomgangatho wakho.
I-Hydroxypropyl Methylcelceltulose inakho ukubambelela ngokukhuthaza ukwandisa amandla e-chypsing gypsing kwi-gypsum ye-gypsing ye-Gypsim. Xa umxube usetyenziswa, i-HPMC iqinisekisa ukuba umxube unamathela kwi-substrate, esenza iqhina elisisigxina nelomeleleyo. Oku kuphelisa isidingo somatshini womatshini, ukonga ixesha kunye nemali ngexesha lofakelo.
Enye inzuzo ye-HPMC kwi-Gypsim-esekwe kwiGyppum yigalelo layo kugcino lwendalo kumzi-mveliso wokwakha. I-HPMC inobuhlobo obuyingqongileyo kwaye kulula ukuyilahla, iyenza ibe yindlela ekhuselekileyo nenendlela yokuzinza kwamanye imichiza yamachiza.
I-HydroxyPOpyl Methylcelcelsele (i-HPMC) iqinisekisiwe ukuba sisithako esibalulekileyo kwizicelo zokuzimela ezizeziseko zeGyppum. Ngokufaka igalelo kukungaguquguquki, umgangatho kunye nokufana kunye nokufana komxube, i-HPMC kuphucula ukuqina kunye nokubulala izinto ezibonakalayo. Izibonelelo zayo zokuphuculwa kwamandla ezibonakalayo ziyanceda ukugcina ixesha lecandelo kunye nemali. Ukongeza, ukusetyenziswa kwe-HPMC kukhuthaza ukuzinza kwendalo, okwenza ukhetho olukhethiweyo kumzi mveliso wokwakha.
