I-HPMC Ekwakhiweni

I-Hydroxypropyl methyl cellulose HPMC i-cellulose ye-polymer yemvelo njengempahla eluhlaza, ngochungechunge lokucutshungulwa kwamakhemikhali futhi eyenziwe nge-non-ionic cellulose ether. Ayinaphunga, ayinambitheki, impushana emhlophe engenabuthi enwebeka ibe isixazululo se-colloid esicacile noma esinamafu kancane emanzini abandayo. Ngokuqina, ukunamathela, ukuhlakazeka, i-emulsification, ukwakheka kwefilimu, ukumiswa, i-adsorption, ijeli, umsebenzi ongaphezulu, ukugcinwa komswakama nokuvikelwa kwe-colloidal, njll. I-Hydroxypropyl methyl cellulose HPMC, i-methyl cellulose MC ingasetshenziswa ezintweni zokwakha, imboni yokumboza, i-resin yokwenziwa, imboni ye-ceramic, imithi, ukudla, izindwangu, ezolimo, amakhemikhali nsuku zonke nezinye izimboni.

I-Chemical equation:
[C6H7O2(OH) 3-MN (OCH3) M (OCH2CH(OH)CH3) N] X

Izakhiwo ze-HPMC ezisetshenziswa Ekwakhiweni
1. Ukugcinwa kwamanzi
I-Hydroxypropyl methyl cellulose HPMC yokwakha ivimbela ukumuncwa kwamanzi ngokweqile yi-substrate, futhi amanzi kufanele agcinwe kusimende ngangokunokwenzeka ngesikhathi sokuqeda ukuqiniswa kwe-gypsum. Lesi sakhiwo saziwa ngokuthi ukugcinwa kwamanzi, futhi silingana ne-viscosity yesakhiwo esithile se-hydroxypropyl methyl cellulose isisombululo se-HPMC ku-stucco, lapho i-viscosity yesisombululo iphakama, umthamo wokugcina amanzi ukhuphuka.
Ngokushesha lapho okuqukethwe kwamanzi kunyuswa, amandla okugcina amanzi ayancipha, ngoba amanzi andayo ahlanza ukwakhiwa kwesisombululo se-hydroxypropyl methyl cellulose HPMC, okuholela ekwehleni kwe-viscosity.
2. Ukumelana ne-Sag
I-stucco ekwazi ukumelana nokugeleza nokulenga ivumela umakhi ukuthi afake i-coat ewugqinsi ngaphandle kokugeleza okuqondile, okusho futhi ukuthi i-stucco ngokwaso siyi-thixotropic, ngaphandle kwalokho sishelela phansi ngesikhathi sokwakhiwa.
3. Yehlisa i-viscosity, ukwakhiwa okulula
Ngokungeza izinhlobonhlobo zemikhiqizo ekhethekile ye-hydroxypropyl methyl cellulose HPMC, i-viscosity ephansi kanye nokwakhiwa okulula kungatholakala ku-gypsum plaster, kusetshenziswa isakhiwo sezinga eliphansi le-viscosity esinikezelwe i-hydroxypropyl methyl cellulose HPMC, i-viscosity encane kanye nokwakhiwa okulula, nokho, isakhiwo esine-viscosity esizinikezele. I-hydroxypropyl methyl cellulose Ikhono lokugcina amanzi le-HPMC libuthakathaka, lidinga ukukhuphula inani elengeziwe.
4. Izinga lokukhula kwe-stucco
Ngenani elinqunyiwe lodaka olomile, ukonga kakhulu ukukhiqiza umthamo wodaka olumanzi ophezulu, ongafinyelelwa ngokungeza amanzi amaningi namabhamuza. Kodwa amanzi amaningi namabhamuza kungalimaza amandla.

(2) Thuthukisa amandla aluhlaza, ukhuthaze umphumela wokwelapha we-hydration, wandise isivuno somkhiqizo ophelile.

10.udaka oluxubile
ekugcinweni kwamanzi odaka oluxubekile kungcono kunemikhiqizo ejwayelekile, ukuqinisekisa ukugcwala okugcwele kwezinto zikasimende ezingaphili, kuvimbela ngokuphawulekayo ukomisa ngokushesha okubangelwa ukuncipha kwamandla ebhondi, nokomisa ukuncipha okubangelwa ukuqhekeka. I-HPMC futhi inomphumela othile wokungenisa umoya, imikhiqizo yodaka exubile ye-HPMC ekhethekile, inani elifanele lokungenisa umoya, amabhamuza afanayo namabhamuza amancane, ingathuthukisa amandla kanye nokucwebezela kodaka oluxutshwe ngaphambili. Imikhiqizo ekhethekile ye-HPMC ye-premixed mortar inomphumela othile wokunciphisa, ingandisa isikhathi sokuvula sodaka oluxutshwe ngaphambili, inciphise ubunzima bokwakha.
