Dab tsi yog Cov Khoom Siv Tseem Ceeb rau Kev Tsim Kho Plaster Putty?

Kev tsim kho plaster putty, tseem hu ua gypsum putty, yog ib hom khoom siv hauv tsev siv los txhaws qhov khoob thiab tawg hauv cov phab ntsa, qab nthab, thiab lwm qhov chaw.Nws yog tsim los ntawm kev sib xyaw ntawm cov khoom siv raw, txhua qhov ua haujlwm rau lub hom phiaj tshwj xeeb hauv kev tsim.Cov ntaub ntawv tseem ceeb rau kev tsim kho plaster putty yog:

1. Gypsum Powder: Gypsum yog cov khoom tseem ceeb hauv kev tsim plaster putty.Nws yog cov ntxhia mos uas feem ntau pom nyob rau hauv qhov xwm txheej thiab tuaj yeem ua rau hauv cov hmoov zoo.Gypsum hmoov yog ntxiv rau cov hmoov sib tov kom muab lub zog thiab ruaj khov rau cov khoom kawg.Nws kuj ua raws li kev khi tus neeg sawv cev uas pab cov putty adhere rau saum npoo.
2. Calcium Carbonate: Calcium carbonate yog lwm cov khoom tseem ceeb hauv kev tsim plaster putty.Nws yog siv los txhim kho qhov sib xws ntawm putty thiab txo nws cov shrinkage thaum lub sij hawm ziab.Calcium carbonate kuj tseem pab ua kom muaj qhov khoob me me thiab cov kab nrib pleb hauv qhov chaw, ua rau qhov kawg tshwm sim smoother thiab ntau dua.
3. Talcum Powder: talcum hmoov yog siv rau hauv kev tsim kho plaster putty los txhim kho nws txoj haujlwm thiab ua kom yooj yim rau kev thov.Nws kuj tseem pab txo qis cov dej uas xav tau los sib tov cov putty, uas ua rau txo lub sij hawm ziab.
4. Polymer Additives: Polymer additives feem ntau ntxiv rau kev tsim kho plaster putty los txhim kho nws cov khoom.Cov additives no tuaj yeem suav nrog acrylic lossis vinyl resins uas muab ntxiv zog, yoog raws, thiab dej tsis kam rau cov khoom kawg.Lawv kuj tuaj yeem txhim kho qhov adhesion ntawm putty rau saum npoo, ua kom nws ruaj khov dua lub sijhawm.
5. Dej: Dej yog ib qho tseem ceeb ntawm kev tsim plaster putty.Nws yog siv los sib tov cov ntaub ntawv raw ua ke thiab tsim kom muaj kev sib xyaw ua haujlwm uas tuaj yeem siv rau saum npoo.Tus nqi ntawm cov dej siv hauv qhov sib tov tuaj yeem cuam tshuam rau qhov sib xws thiab lub sijhawm ziab ntawm lub putty.

Hauv kev xaus, cov ntaub ntawv tseem ceeb rau kev tsim kho plaster putty muaj xws li gypsum hmoov, calcium carbonate, talcum hmoov, polymer additives, thiab dej.Cov ntaub ntawv no ua haujlwm ua ke los tsim kom muaj kev sib tw, txawm tias ua tiav uas muaj zog, ruaj khov, thiab tiv taus dej puas.
