Hydroxyprusyl methylcellose (HPMC) ndeyekuchinja kwakawanda kunoshandiswa zvakanyanya mune yekuvaka indasitiri, kunyanya muzvimiro zvePlaster. Gypsum Plaster, anozivikanwawo sePlaster of Paris, chinhu chakakurumbira chivakwa chinoshandiswa kuunganidza madziro nemazera. HPMC inoita basa rakakosha mukuvandudza mashandiro uye kuita kwe gypsum plaster.
HPMC ndeye isiri-ionic cellulose ether inowanikwa kubva kune yakasikwa polymer cellulose kuburikidza neyekutevedzana kwemakemikari ekugadzirisa. Iyo inogadzirwa nekurapa cellulose ine profilyone oxide uye methyl chloride. Chigadzirwa chinokonzeresa ndeye chena hupfu hunonyura mumvura uye anoumba chirevo cheViscous.
Heano mamwe ezvikamu zvakakosha zveHPMC yePlaster:
1. Kuchengeta mvura:
Imwe yemabasa ekutanga eHPMC muGypsum ndeyekuita kwayo kwemvura. Izvo zvinobatsira kudzivirira kurasikirwa nekukurumidza kwemununure panguva yekuomesa maitiro, uchibvumira zvakanyanya kudzorwa uye kunyange kuiswa kweplaster. Izvi zvakakosha kuti uwane simba rinodiwa uye kusawirirana kweplaster.
2. Kuvandudza Kugadziriswa:
HPMC inosimudzira kushanda kweiyo gypsum plaster nekupa nguva iri nani nguva yekuvhurika uye kuwedzera kutsvedza kuramba. Izvi zvinoita kuti zvive nyore kushandisa uye kuparadzira stucco pamusoro pechiso, zvichikonzera mudhara, zvakanyanya kunyange kupedzisa.
3. ADhemion uye kubatana:
HPMC AIDS mune yakadhindwa yeGypsum Plaster kune dzakasiyana Substrates. Inovandudza kudenha pakati pe stucco uye pasi pechiso, ichiratidza kuti isingaperi uye isingagadzike kupedzisa. Mukuwedzera, HPMC inokwidziridza kubatana kwePlaster pachayo, nekudaro kuwedzera simba nekudzora kupaza.
4. Kukakavara Kunoita:
Muchigadzirwa cheGypsum, HPMC zviito sediki, ichikanganisa zvevhiza yemusanganiswa weGypsum. Uku kukonzeresa simba kwakakosha kuzadzisa iyo yaunoda kusawirirana uye kuumbwa panguva yekushandisa. Izvo zvakare zvinobatsira kudzivirira stucco kubva mukutsvaira kana kudonha pane vertical nzvimbo.
5. Gadza Nguva Yekudzora:
Kudzora nguva yekugara yeGypsum Plaster inokoshesesa muArcitectural application. HPMC inogona kugadzirisa nguva yekuisa kuti ipe iyo yekuchinjika kuti isangane chaiyo purojekiti zvinodiwa. Izvi zvinonyanya kukosha kumapurojekiti akakura izvo zvingangoda kusiyana kwakasiyana nguva.
6. Chishandiso pane porosity:
Kuvapo kweHPMC kunobata porosity ye gypsum. Yakanyatsogadzirwa Plaster ine HPMC inogona kuwedzera kupinza mvura kupinda mumvura uye kuderedza porosity, nekudaro kuri kuwedzera kusimba uye kuramba zvinhu zvakatipoteredza.
7. Kuenderana nevamwe vanowedzera:
HPMC inoenderana nemhando dzakasiyana siyana dzekuwedzera dzinowanzo kushandiswa mune gypsum mafomu. Izvi zvinowanzanisa zvinobvumirana plaster zvinomwe zvinosanganiswa kuti ugadzirwe kuzadzisa zvakananga zviitiko zvekuita uye zvinodiwa application.
8. Kufunga nezvemamiriro ekunze:
HPMC inowanzoonekwa yakachengeteka uye yakasarudzika ine hushamwari. Izvo hazvina kuita zvepfu uye hazvisunungure zvinhu zvinokuvadza panguva kana mushure mekuparadza. Izvi zvinoenderana nekuwedzera kusimbisa kwekuriritira uye eco-hushamwari maitiro ekuvaka.
HydroxyPropyl methylcellose (HPMC) inoita basa rakakosha mukuvandudza mashandiro eGypsum mune yekuvaka maapplication. Kuchengeta kwemvura kwaro, kuvandudzika kwekushandira, kudenha, kurongedza nguva yekudzora, kuenderana nezvimwe zvinowedzera uye kufunga kwezvakatipoteredza zvinoita kuti ive yakanyanya kuwanda-yakakwirira gypsum mafomu ekugadzira. Sezvo maitiro ekuvaka anoenderera mberi nekuchinja, HPMC inoramba iri chinhu chakakosha mukuvandudza kushanda uye kusimba kweiyo gypsum plaster mune akasiyana emabasa ekuvaka uye ekuvaka mapurojekiti ekuvaka uye ekuvaka.
