HPMC Rau Phab Ntsa Putty plasters Skim Coat

HPMC (Hydroxypropyl Methyl Cellulose) feem ntau yog siv los ua ib qho ntxiv rau hauv phab ntsa putty, stucco thiab deg txheej formulations.Nws yog multifunctional polymer muab los ntawm cellulose uas muaj ntau yam zoo hauv cov ntawv thov no.Nov yog li cas HPMC siv rau hauv phab ntsa putty, stucco thiab skim coats:

Kev tuav dej: HPMC ua kom cov dej khaws cia ntawm qhov sib tov, cia cov khoom siv tau ntev dua.Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kev tsim kho daim ntawv thov uas ncua sij hawm ua hauj lwm yuav tsum tau.

Kev ua haujlwm tau zoo: HPMC txhim kho kev ua haujlwm ntawm qhov sib tov, ua kom yooj yim rau kev thov thiab sib kis sib npaug ntawm qhov chaw.Nws pab ua kom tiav qhov du thiab txawm tias tiav.

Adhesion: HPMC txhim kho cov adhesion ntawm phab ntsa putty, stucco los yog nto txheej rau lub substrate, kom ntseeg tau ib tug zoo dua daim ntawv cog lus thiab txo qhov zoo ntawm kev tawg los yog tev.

Sag Resistance: HPMC pab txo qis sag los yog kev sib tsoo ntawm cov khoom siv ntsug lossis saum taub hau.Nws imparts thixotropic zog, cia cov sib tov los tuav nws cov duab thiab nyob rau hauv qhov chaw.

Crack resistance: Los ntawm kev ntxiv HPMC, cov txheej txheej kawg nthuav tawm txhim kho kev ua haujlwm tawg vim nws qhov yooj yim dua.Qhov no pab tiv thaiv cov kab nrib pleb los ntawm substrate shrinkage los yog txav mus.

Zaj duab xis tsim: HPMC tsim ib zaj duab xis thaum qhuav, uas yuav pab txhim kho lub durability thiab dej tsis kam ntawm phab ntsa putty, stucco los yog nto txheej.Nws tiv thaiv lub hauv paus nto los ntawm noo noo nkag mus thiab prolongs nws lub neej.

Rheology Control: HPMC ua raws li kev hloov kho rheology, cuam tshuam rau kev ntws thiab sib xws ntawm qhov sib xyaw.Nws ua kom yooj yim daim ntawv thov los ntawm kev tswj cov viscosity thiab tiv thaiv kev sib cais lossis kev sib cais ntawm cov khoom siv.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi pes tsawg ntawm HPMC thiab lwm yam khoom xyaw yuav txawv raws li cov khoom xav tau, daim ntawv thov txheej txheem thiab ib puag ncig.Cov neeg tsim khoom ntawm phab ntsa putty, plaster thiab skim txheej cov khoom feem ntau muab kev taw qhia txog kev siv HPMC hauv lawv cov ntaub ntawv cov ntaub ntawv lossis cov lus piav qhia ntawm cov khoom.
