Nws txo qhov rub thiab kev tiv thaiv thaum lub sijhawm troweling lossis nthuav dav, ua rau kev siv du thiab sib xws dua ntawm cov chaw ntsug lossis saum toj.
3. Kev Sib Txuas Zoo Dua: HPMC ua rau kev sib txuas ntawm cov tshuaj pleev thaiv hnub rau ntau yam khoom siv, xws li cov pob zeb ua vaj tse, masonry, ntoo, thiab hlau zoo dua. Nws txhim kho lub zog sib txuas ntawm cov tshuaj pleev thaiv hnub thiab cov khoom siv, txo qhov kev pheej hmoo ntawm kev tawg lossis kev sib cais dhau sijhawm.
4. Txo Qhov Ntsws Thiab Kev Nthuav: HPMC pab txo qhov ntsws thiab kev tawg hauv cov tshuaj pleev thaiv tsev los ntawm kev txhim kho nws txoj kev sib koom ua ke thiab txo cov dej evaporation thaum lub sijhawm kho. Qhov no ua rau cov tshuaj pleev thaiv tsev ruaj khov dua thiab tiv taus kev tawg uas tswj tau nws qhov kev ncaj ncees dhau sijhawm.
5. Kev Tiv Thaiv Sag Zoo Dua: HPMC muab kev tiv thaiv sag rau cov tshuaj rwb thaiv tsev, tso cai rau nws siv rau hauv cov khaubncaws sab nraud povtseg yam tsis muaj kev poob qis lossis sagging. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov ntsug lossis saum toj kawg nkaus uas tswj cov tuab sib npaug yog qhov tseem ceeb.
6. Lub Sijhawm Teeb Tsa Tswj: HPMC siv tau los tswj lub sijhawm teeb tsa ntawm cov khoom siv rwb thaiv tsev los ntawm kev kho nws cov dej noo thiab cov khoom rheological. Qhov no tso cai rau cov neeg cog lus kho lub sijhawm teeb tsa kom haum rau cov kev xav tau tshwj xeeb ntawm qhov project thiab cov xwm txheej ib puag ncig.
7. Txhim Kho Rheology: HPMC txhim kho cov khoom rheological ntawm cov tshuaj pleev thaiv rwb thaiv tsev, xws li viscosity, thixotropy, thiab shear thinning tus cwj pwm. Nws ua kom muaj kev ntws thiab qib sib xws, pab txhawb kev siv thiab ua tiav ntawm cov tshuaj pleev thaiv rau ntawm cov chaw tsis sib xws lossis cov qauv.
8. Cov Khoom Siv Rwb Thaiv Tsev Zoo Dua: HPMC tuaj yeem txhim kho cov khoom siv rwb thaiv tsev ntawm cov tshuaj mortar los ntawm kev txo cov cua sov hloov pauv los ntawm cov khoom siv. Qhov no pab txhim kho kev siv hluav taws xob ntawm cov tsev thiab cov qauv, pab txo cov nqi cua sov thiab txias.

Qhov ntxiv ntawm Hydroxypropyl methylcellulose (HPMC) rau hauv cov qauv rwb thaiv tsev ua rau lawv cov kev ua tau zoo, kev ua haujlwm tau zoo, kev ruaj khov, thiab cov khoom rwb thaiv tsev zoo dua. Nws pab cov neeg cog khoom ua tiav kev siv du thiab sib xws dua thiab ua kom muaj kev ua tau zoo ntev hauv ntau yam kev siv hauv kev tsim kho.
