Qhov cuam tshuam ntawm HPMC ntawm Gypsum

HydroxyPropyyl methylcellose (HPMC) feem ntau siv hauv gypsum cov khoom kom txhim kho lawv cov kev ua tau zoo thiab cov khoom. Nov yog qee qhov cuam tshuam ntawm HPMC ntawm Gypsum:

1. Dej khaws cia: HPMC ua raws li cov khoom siv tswj kav dej hauv gypsum-based khoom, xws li cov sib txuas ua ke, cov plasters, thiab kev sib txuas lus tus kheej. Nws pab tiv thaiv kom tsis txhob poob dej sai thaum sib xyaw thiab kev thov, pub rau kev txhim kho lub zog ua haujlwm thiab qhib lub sijhawm qhib.
2. Txhim kho kev ua haujlwm: Qhov sib ntxiv ntawm HPMC mus rau Gypsum cov qauv txhawb lawv txoj kev ua haujlwm los ntawm kev txhim kho qhov tsis sib xws, thiab yooj yim ntawm daim ntawv thov. Nws txo cov cab thiab kev tawm tsam thaum troweling lossis kis tau, ua rau smoother thiab ntau qhov chaw sib txawv.
3. Txo cov shrinkage thiab tawg: HPMC pab kom txo qis shrinkage thiab tawg hauv kev txhim kho cov cohesion thiab cov nplaum ntawm cov khoom. Nws ua cov yeeb yaj kiab tiv thaiv ib puag ncig ntawm cov av gypsum, txo cov dej evaporation thiab txhawb txawm tias muaj kev pheej hmoo ntawm qhov tsis xws luag.
4. Txhim kho txoj hlua khi: HPMC txhim kho lub zog ntawm gypsum thiab ntau yam substrates, xws li wreenwall, pob zeb, thiab hlau. Nws txhim kho cov nplaum ntawm cov sib txuas ua ke thiab cov plasters rau lub substrate, uas ua rau muaj zog thiab ntau ruaj khov tiav tas.
5. Txhim kho cov Sag Kuj: HPMC imparts sag kam rau gypsum-based cov ntaub ntawv, xws li cov sib txuas ntsug thiab cov ntawv luam tawm. Nws pab kom tiv thaiv npleem lossis sagging ntawm cov khoom siv thaum daim ntawv thov, tso cai rau kev muab cov khoom ntsug yooj yim lossis cov nyiaj laus dua.
6. Lub sijhawm tswj lub sijhawm: HPMC tuaj yeem siv los tswj lub sijhawm teeb tsa ntawm Gypsum cov khoom lag luam los ntawm kev kho lub viscosity thiab hydration tus nqi ntawm kev tsim qauv. Qhov no tso cai rau kev thov thiab tso cai rau cov neeg cog lus los kho lub sijhawm teem sijhawm kom haum cov kev xav tau tshwj xeeb tshwj xeeb.
7. Enhanced rheology: HPMC txhim kho lub zog rheological ntawm gypsum tsim, xws li viscotropy, thixotrostropy, thiab shear thawb tus cwj pwm. Nws ua kom muaj zog sib xws thiab cov nuj nqis leviing, yooj yim rau daim ntawv thov thiab xov ntawm gypsum-based cov ntaub ntawv.
8. Txhim kho cov khoom siv suab paj nruag thiab ua tiav: muaj ntawm HPSPSUM cov khoom tau tshwm sim hauv smoother thiab ntau cov kev sib txawv ntawm cov xuab zeb thiab ua tiav. Nws txo qis saum npoo roughness, porosity, thiab nto tsis zoo, ua rau muaj kev ua tiav zoo uas tau npaj txhij rau kev pleev xim lossis kho kom zoo nkauj.

Qhov kev sib txuas ntawm HPMC rau Gypsum cov khoom ua rau lawv cov kev ua tau zoo, ua haujlwm kom haum rau ntau yam ntawm kev kho cov ntawv thov, suav nrog cov chaw kho kom zoo, nrog kho cov tshuab ziab khaub ncaws, thiab kho kom ntuas kom tob.
