I-HPMC kulwakhiwo

I-Hydroxypropyl methyl cellulose i-HPMC yi-cellulose yendalo yepolymer njengempahla ekrwada, ngothotho lokusetyenzwa kweekhemikhali kunye ne-non-ionic cellulose ether.Azinavumba, azinancasa, zingumgubo omhlophe ongeyotyhefu othi unyuke ube sisinyibiliko esicacileyo okanye esinamafu kancinane kwicolloid kumanzi abandayo.Ngokuqina, ukunamathela, ukusabalalisa, i-emulsification, ukubunjwa kwefilimu, ukumiswa, i-adsorption, i-gel, umsebenzi ophezulu, ukugcinwa komswakama kunye nokukhusela i-colloidal, njl. ishishini leceramic, amayeza, ukutya, amalaphu, ezolimo, imichiza yemihla ngemihla kunye namanye amashishini.

Inxaki yemichiza:
[C6H7O2(OH) 3-MN (OCH3) M (OCH2CH(OH)CH3) N] X

Iipropati ze-HPMC ezisetyenziswa kuLwakhiwo
1. Ukugcinwa kwamanzi
IHydroxypropyl methyl cellulose HPMC yolwakhiwo inqanda ukufunxwa ngokugqithisileyo kwamanzi yi-substrate, kwaye amanzi kufuneka agcinwe kudaka kangangoko ngexesha lokugqitywa kokuqina kwegypsum.Le propati yaziwa ngokuba ngukugcinwa kwamanzi, kwaye ihambelana ne-viscosity yesakhiwo esithile se-hydroxypropyl methyl cellulose isisombululo se-HPMC kwi-stucco, i-viscosity ephezulu yesisombululo, iphezulu umthamo wokugcina amanzi.
Ngokukhawuleza ukuba umthamo wamanzi unyuswe, umthamo wokugcinwa kwamanzi uyancipha, ngenxa yokuba ukwanda kwamanzi kuhlambulule ukwakhiwa kwesisombululo se-hydroxypropyl methyl cellulose HPMC, okubangelwa ukuhla kwe-viscosity.
2. Ukumelana ne-Sag
I-stucco ekwazi ukumelana nokuhamba kunye nokuxhoma ivumela umakhi ukuba afake i-coat eshinyeneyo ngaphandle kokuhamba ngokuthe nkqo, oku kuthetha ukuba i-stucco ngokwayo i-thixotropic, ngaphandle koko i-slide ezantsi ngexesha lokwakha.
3. Ukunciphisa i-viscosity, ukwakhiwa okulula
Ngokongeza iintlobo ngeentlobo zezakhiwo ezizodwa ze-hydroxypropyl methyl cellulose iimveliso ze-HPMC, i-viscosity ephantsi kunye nokwakhiwa okulula kunokufumaneka kwi-gypsum plaster, usebenzisa isakhiwo esisezantsi se-viscosity esinikezelwe i-hydroxypropyl methyl cellulose HPMC, i-viscosity encinci kunye nokwakhiwa okulula, nangona kunjalo, isakhiwo se-viscosity esizinikezele. I-hydroxypropyl methyl cellulose I-HPMC yokugcina amanzi ibuthathaka, ifuna ukunyusa isixa esongezelelweyo.
4. Umyinge wokukhula kwamandla estucco
Ngomlinganiselo omiselweyo wodaka olomileyo, lunoqoqosho ngakumbi ukuvelisa umthamo wodaka olumanzi oluphezulu, olunokufezekiswa ngokudibanisa amanzi amaninzi kunye namaqamza.Kodwa amanzi amaninzi kunye namaqamza angonakalisa amandla.
