Ua ib yam khoom siv hauv tsev, hydroxypropyl methylcellulose tseem ceeb dua hauv kev lag luam kev tsim kho. Lub luag haujlwm tseem ceeb ntawm hydroxypropyl methylcellulose yog dab tsi?
1. Cov av nplaum masonry
Nws ua rau kom cov nplaum lo rau ntawm qhov chaw ntawm lub masonry thiab ua rau kom cov dej nyob hauv, ua rau lub zog ntawm cov mortar zoo dua, ua rau lubricity thiab plasticity zoo dua, uas yog qhov zoo rau kev ua haujlwm ntawm kev tsim kho. Nws tsis yog tsuas yog ua rau kev tsim kho yooj yim xwb, tab sis kuj txuag lub sijhawm thiab txhim kho kev siv nyiaj.
2. Daim ntawv nplaum
Vim tias hydroxypropyl methylcellulose muaj cov dej zoo heev, nws tuaj yeem ncua lub sijhawm txias thiab muaj lubricity siab kom ua rau kev siv du dua. Zoo txhim kho qhov zoo ntawm qhov chaw, muab cov qauv du thiab sib xws, thiab ua rau qhov chaw sib txuas muaj zog dua.
3. Cov cement-based gypsum
Ua kom cov plaster sib npaug zoo, ua rau cov plaster yooj yim dua rau kev siv, thiab ua kom cov dej ntws thiab lub zog nqus tau zoo dua rau kev ua haujlwm zoo dua. Nws muaj cov dej khaws cia siab, ua rau lub sijhawm ua haujlwm ntawm cov mortar ntev dua. Tsis tas li ntawd, nws tuaj yeem tswj tau qhov nkag mus ntawm huab cua, yog li tshem tawm cov kab nrib pleb me me hauv cov txheej thiab ua rau qhov chaw du.
4. Cov khoom siv gypsum
Nws ua rau lub sijhawm ua haujlwm ntawm cov mortar ntev dua thiab tsim kom muaj zog dua thaum lub sijhawm teeb tsa. Los ntawm kev tswj qhov sib npaug ntawm cov mortar, qhov zoo ntawm cov txheej txheem saum npoo zoo dua.
5. Cov xim pleev xim thiab cov tshuaj pleev xim uas siv dej ua ke
Nws tuaj yeem ua kom lub txee ntev dua los ntawm kev tiv thaiv cov khoom khov kom tsis txhob poob thiab muaj kev sib haum xeeb zoo heev thiab muaj kev ruaj khov ntawm lub cev. Nws yaj sai thiab tiv thaiv kev sib sau ua ke, pab ua kom yooj yim rau cov txheej txheem sib tov. Tsim cov yam ntxwv ntws zoo suav nrog kev tawg tsawg thiab kev sib npaug zoo, ua kom qhov chaw tiav zoo heev thiab tiv thaiv cov xim poob. Txhim kho qhov viscosity ntawm cov xim strippers dej thiab cov organic solvent xim strippers kom cov xim strippers yuav tsis ntws tawm ntawm qhov chaw ntawm cov khoom ua haujlwm.
6. Cov kua nplaum pobzeb
Cov khoom xyaw qhuav sib xyaw yooj yim sib tov thiab tsis sib sau ua ke, txuag lub sijhawm ua haujlwm vim yog kev siv sai dua thiab ua haujlwm tau zoo dua, txhim kho kev ua haujlwm thiab txo cov nqi. Los ntawm kev ncua sijhawm txias, kev ua haujlwm zoo dua thiab kev nplaum zoo heev.
7. Cov ntaub ntawv hauv pem teb uas nws tus kheej leveling
Muab viscosity thiab siv tau ua cov tshuaj tiv thaiv kev sib sau ua ke los pab txhim kho kev ua haujlwm ntawm kev teeb tsa hauv pem teb. Los ntawm kev tswj cov dej khaws cia, cov kab nrib pleb thiab kev ntsws tuaj yeem txo qis heev.
8. Kev Tsim Khoom ntawm Cov Pob Zeb Uas Muaj Cov Cim
Txhim kho kev ua haujlwm ntawm cov khoom extruded, muaj lub zog sib txuas thiab lubricity siab dua, thiab txhim kho lub zog ntub thiab kev nplaum ntawm cov ntawv extruded.
