Sab saum toj 5 Cov Khoom xyaw hauv Phab Ntsa Putty Formula

Phab ntsa putty yog cov khoom siv rau smoothening thiab leveling phab ntsa ua ntej pleev xim. Cov txheej txheem ntawm phab ntsa putty tuaj yeem sib txawv nyob ntawm cov chaw tsim khoom thiab cov qauv tsim tshwj xeeb, tab sis feem ntau, nws muaj ntau yam khoom xyaw tseem ceeb. Nov yog tsib cov khoom xyaw uas feem ntau pom nyob rau hauv cov qauv phab ntsa putty:

1. Calcium Carbonate (CaCO3):
   • Calcium carbonate yog ib qho kev muab tub lim siv hauv phab ntsa putty formulations. Nws muab ntau rau lub putty thiab pab kom ua tiav ib qho kev ua tiav ntawm cov phab ntsa.
   • Nws kuj tseem txhawb nqa qhov opacity thiab whiteness ntawm putty, txhim kho nws qhov kev zoo nkauj.
2. Dawb Cement:
   • Cov cement dawb ua raws li kev sib khi hauv phab ntsa putty formulations, pab khi rau lwm cov khoom xyaw ua ke thiab ua raws cov putty rau ntawm phab ntsa.
   • Nws muab lub zog thiab durability rau lub putty, kom ntseeg tau tias nws tsim ib tug ruaj khov puag rau painting.
3. Hydroxyethyl Methyl Cellulose (MHEC):
   • Hydroxyethyl methylcellulose yog ib tug thickening tus neeg sawv cev uas feem ntau siv nyob rau hauv phab ntsa putty los txhim kho nws workability thiab sib xws.
   • Nws pab tiv thaiv sagging los yog slumping ntawm lub putty thaum thov thiab txhim khu nws adhesion rau phab ntsa nto.
4. Polymer Binder (Acrylic Copolymer):
   • Polymer binders, feem ntau acrylic copolymer, yog ntxiv rau phab ntsa putty formulations los txhim kho lawv adhesion, yooj, thiab dej tsis kam.
   • Cov polymers no txhim kho tag nrho cov kev ua tau zoo ntawm putty, ua kom nws ruaj khov thiab tiv taus kev tawg los yog tev lub sijhawm.
5. Calcium Sulphate (CaSO4):
   • Calcium sulphate qee zaum muaj nyob rau hauv phab ntsa putty formulations los txhim kho lawv lub sij hawm teem thiab txo shrinkage thaum ziab.
   • Nws pab kom ua tiav qhov du thiab txawm tias tiav ntawm phab ntsa nto thiab pab txhawb rau tag nrho kev ruaj ntseg ntawm putty.

Cov no yog qee cov khoom xyaw tseem ceeb uas pom nyob rau hauv cov qauv phab ntsa putty. Ntxiv cov additives xws li preservatives, dispersants, thiab pigments kuj yuav suav nrog nyob ntawm seb cov kev cai tshwj xeeb ntawm formulation. Nws yog ib qho tseem ceeb kom ua raws li cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo rau kev npaj thiab siv cov phab ntsa putty kom ntseeg tau tias kev ua tau zoo thiab cov txiaj ntsig.
