Hydroxypropyl methylcellulose (HPMC)yog ib qho uas tsis yog-ionic cellulose ether dav siv hauv cov khoom siv hauv tsev. Nws lub luag haujlwm tseem ceeb hauv cov khoom siv hauv tsev yog txhawm rau txhim kho kev tsim kho, txhim kho cov dej tuav thiab adhesion ntawm cov ntaub ntawv, thiab txhim kho kev ua haujlwm ntawm cov ntaub ntawv. HPMC tau dhau los ua ib qho tseem ceeb ntxiv rau ntau yam khoom siv vim nws cov tshuaj lom neeg thiab lub cev zoo heev. Nws yog dav siv hauv cov khoom siv hauv tsev xws li cement mortar, pobzeb nplaum, putty hmoov, coatings, thiab gypsum khoom. Cov hauv qab no yog cov yam ntxwv thiab cov txiaj ntsig ntawm HPMC hauv cov khoom siv hauv tsev:
1. Cov yam ntxwv ntawm HPMC hauv cov khoom siv hauv tsev
Kev tuav dej zoo heev
Ib qho tseem ceeb tshaj plaws ntawm HPMC yog nws cov dej tuav tau zoo. Hauv cov cement-based thiab gypsum-raws li cov ntaub ntawv, HPMC tuaj yeem txo cov dej tsis zoo, tiv thaiv kev ziab ntawm cov cement thiab gypsum thaum ntxov, thiab txhim kho kev ncaj ncees ntawm cov dej tshuaj tiv thaiv, yog li txhim kho lub zog thiab adhesion ntawm cov ntaub ntawv.
Txhim kho kev tsim kho kev ua haujlwm
Thaum lub sij hawm tsim kho, HPMC tuaj yeem txhim kho kev ua haujlwm ntawm mortar thiab ua kom kev tsim kho kom zoo dua. Nws tuaj yeem txhim kho lubricity ntawm cov ntaub ntawv zoo, txo kev sib txhuam thaum siv, ua kom scraping ntau yam thiab du, thiab txhim kho kev tsim kho.
Txhim kho adhesion
HPMC tuaj yeem txhim kho qhov adhesion ntawm substrates xws li cov cement thiab gypsum, yog li cov khoom xws li mortar, putty hmoov, thiab cov nplais nplaum tuaj yeem ua kom ruaj khov rau hauv lub hauv paus nto, txo cov teeb meem xws li hollowing thiab ntog tawm, thiab txhim kho lub neej kev pab cuam ntawm lub tsev cov ntaub ntawv.
Kho cov khoom sib xws
HPMC tuaj yeem kho cov viscosity ntawm cov ntaub ntawv hauv tsev los tiv thaiv mortar los ntawm stratifying, los ntshav los yog sagging thaum lub sij hawm sib xyaw thiab kev tsim kho, kom nws muaj kev ncua zoo dua thiab sib xws, thiab txhim kho kev tsim kho.
Lub sijhawm ua haujlwm txuas ntxiv
HPMC tuaj yeem txuas ntxiv lub sijhawm qhib ntawm cov ntaub ntawv xws li mortar thiab putty, kom cov neeg ua haujlwm tsim kho muaj sijhawm ntau los kho thiab kho, txhim kho kev tsim kho kom zoo, thiab txo cov khoom pov tseg.
Txhim kho anti-sagging
Nyob rau hauv cov pobzeb nplaum thiab putty hmoov, HPMC tuaj yeem txhim kho lub peev xwm los tiv thaiv sagging ntawm cov khoom, kom nws nyob ruaj khov tom qab kev tsim kho thiab tsis yooj yim rau swb, thiab txhim kho qhov tseeb thiab zoo nkauj ntawm pasting.
Huab cua tsis kam thiab stability
HPMC tseem tuaj yeem tswj hwm nws qhov kev ua tau zoo hauv qhov kub thiab txias, av noo lossis ib puag ncig hnyav, ua kom ruaj khov mus ntev ntawm cov khoom siv hauv tsev, thiab yuav tsis cuam tshuam rau kev tsim kho zoo vim kev hloov pauv ib puag ncig.
Kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom
Raws li ib tug natural cellulose derivative, HPMC yog non-toxic thiab harmless, ua tau raws li tej kev tiv thaiv ib puag ncig, thiab yuav siv tau nyob rau hauv ntsuab cov ntaub ntawv.
2. Cov ntawv thov tshwj xeeb thiab cov txiaj ntsig ntawm HPMC hauv cov khoom siv hauv tsev
Cement mortar
HPMC tuaj yeem txhim kho cov dej tuav ntawm cov cement mortar, tiv thaiv cov mortar kom qhuav sai heev, txo qhov kev pheej hmoo ntawm kev tawg, txhim kho adhesion, ua kom kev tsim kho smoother, thiab txhim kho kev tiv thaiv sagging, kom cov mortar tsis yooj yim plam thaum tsim cov phab ntsa ntsug.
Cov nplaum nplaum
Hauv cov pobzeb nplaum, HPMC txhim kho kev sib txuas ntawm lub zog thiab cov khoom siv tiv thaiv, kom ntseeg tau tias cov vuas tuaj yeem txuas tau ruaj khov, thaum txhim kho kev ua haujlwm ntawm kev tsim kho, txo kev ua haujlwm, thiab txhim kho kev tsim kho.
Putty hmoov
Hauv cov hmoov putty, HPMC tuaj yeem txhim kho kev tsim kho ntawm putty, ua kom scraping smoother, txo cov hmoov, txhim kho adhesion ntawm putty, thiab zoo tiv thaiv lub putty txheej ntawm cracking thiab ntog tawm.
Gypsum khoom
Hauv gypsum-raws li cov ntaub ntawv hauv tsev (xws li gypsum putty, gypsum nplaum, gypsum board, thiab lwm yam), HPMC tuaj yeem txhim kho cov dej tuav ntawm gypsum, txhim kho nws cov kev sib raug zoo, thiab ua kom cov khoom siv gypsum hloov tau thiab ruaj khov.
Cov xim thiab cov xim latex
Hauv cov xim pleev xim dej thiab cov xim latex, HPMC tuaj yeem siv los ua cov thickener thiab dispersant los txhim kho fluidity, tiv thaiv pigment nag lossis daus, txhim kho cov nyhuv txhuam ntawm cov xim, thiab txhim kho cov adhesion thiab dej tsis kam ntawm cov xim zaj duab xis.
Self-leveling mortar
Nyob rau hauv tus kheej-leveling mortar, HPMC tuaj yeem txhim kho nws cov dej ntws, ua kom cov mortar sib npaug ntau dua thaum tsim kho, txhim kho cov nyhuv leveling, thiab txhim khu kev tiv thaiv tawg.
Rwb thaiv tsev mortar
Nyob rau sab nrauv phab ntsa rwb thaiv tsev mortar, HPMC tuaj yeem txhim kho qhov kev sib txuas ntawm cov mortar, ua kom nws zoo dua rau ntawm phab ntsa, thiab tib lub sijhawm txhim kho kev tsim kho thiab ua kom muaj kev ruaj ntseg ntawm cov txheej txheem rwb thaiv tsev.
Raws li kev ua haujlwm siab hauv tsev ntxiv,HPMCyog dav siv nyob rau hauv ntau yam cement-based thiab gypsum-based cov ntaub ntawv. Nws cov dej tuav tau zoo heev, thickening, txhim kho adhesion thiab kev hloov kho kev tsim kho ua rau nws yog ib qho tseem ceeb hauv kev tsim kho kev lag luam. Thaum ua kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv hauv tsev, HPMC tuaj yeem txhim kho kev tsim kho, txo cov khoom poob, thiab txhim kho lub tsev zoo, muab cov kev daws teeb meem zoo dua rau kev tsim kho niaj hnub. Nrog rau kev txhim kho kev tsim kho thev naus laus zis, daim ntawv thov ntawm HPMC yuav txuas ntxiv nthuav dav thiab ua lub luag haujlwm tseem ceeb hauv cov khoom siv vaj tsev ntsuab thiab ib puag ncig zoo.
