HydroxyPropyyl Metylcellulose (HPMC) yog siv dav ntxiv hauv kev tsim kho, tshwj xeeb hauv Gypsum-based cov ntaub ntawv xws li plaster thiab gypsum slurry. Nws yog kev hloov cov tshuaj kho mob cellulose ether tau los ntawm ntuj los polymers, feem ntau cellulose, los ntawm kev sib tw ntawm cov tshuaj lom neeg.
Hauv Gypsum-based cov ntaub ntawv, HPMC pabcuam ntau lub hom phiaj:
Dej khaws cia: HPMC ua yeeb yaj kiab tiv thaiv ib puag ncig ntawm cov pa gypsum, tiv thaiv kev poob los ntawm evaporation. Qhov no pab kom muaj kev sib xws thiab ua haujlwm ntawm Gypsum Slurry Tshaj mus txuas ntxiv, tso cai rau kev thov kom yooj yim dua thiab ua tiav zoo dua.
Txhim kho kev ua haujlwm: los ntawm kev tswj cov hydration tus nqi ntawm gypsum, HPMC txhim kho kev ua haujlwm ntawm cov slurry, ua rau kev sib kis yooj yim, pwm, thiab cov duab. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov xws li plastering thiab molding thiab molding, uas yog qhov kev tswj hwm cov khoom sib xws yog qhov tseem ceeb.
Qaum adhesion: HPMC txhim kho cov nplaum ntawm gypsum rau ntau yam substrates, xws li ntoo, hlau, thiab masonry. Qhov no yog qhov tseem ceeb rau kev ua kom tau zoo thiab tiv thaiv delamination lossis tawg rau hauv cov khoom ua tiav gypsum.
Txo cov khoom mos siagging thiab shrinkage: ntxiv rau HPMC tuaj yeem pab txo cov khoom sib txawv thiab shrinkage thaum lub sij hawm kho, ua rau muaj cov khoom kawg thiab cov khoom kawg.
Txhim kho cov tshuab cov tshuab: HPMC tuaj yeem txhim kho cov khoom siv tshuab ntawm gypsum, suav nrog lub zog, durability, thiab kev tsis kam. Qhov no ua rau lawv haum ntau rau ntau cov kev siv kev siv tsev kho mob, los ntawm sab hauv tiav rau cov ntsiab lus.
Compatibility nrog lwm cov tshuaj sib ntxiv: HPMC tau tshaj tawm ntau yam ntawm lwm cov kev sib ntxiv ntawm cov gypsum cov qauv, xws li retarders, accelerators, thiab huab cua nkag. Qhov no tso cai rau kev txhim kho ntau dua nyob rau hauv cov khoom siv ntawm cov gypsum slurry rau cov kev cai thov.
HPMC ua si tseem ceeb ntawm lub luag haujlwm tseem ceeb hauv Gypsum Slurry Micultity, kev ua haujlwm xws li kev tuav haujlwm, dej khaws cia, thiab cov khoom siv kho tshuab. Nws cov kev siv dav hlau hauv kev tsim kho nws qhov ua tau zoo hauv kev txhim kho kev ua tau zoo thiab versatility ntawm gypsum-based cov ntaub ntawv.
