Lub sijhawm qhib yog lub sijhawm ua haujlwm tau tom qab nplaum rau ntawm lub substrate. Ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hydroxypropyl methylcellulose yog ncua lub sijhawm qhib kom cov neeg teeb tsa tuaj yeem kho qhov chaw ntawm cov vuas kom muaj kev nyab xeeb.
- Kev yooj yim dua rau kev teeb tsa
- Txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov vuas
- Ua raws li cov qauv kev teeb tsa zoo dua
3. Kev Ua Haujlwm Tiv Thaiv Kev Qaug Zog rau Cov Ntawv Thov Ntsug
Rau kev teeb tsa vuas phab ntsa, kev tiv thaiv sag yog qhov tseem ceeb. Cov qib HPMC viscosity kom zoo muab cov cwj pwm tiv thaiv kev plam zoo.
- Tiv thaiv cov vuas vov kom tsis txhob ntog
- Txhim kho kev tuav ntsug
- Txhim kho qhov chaw raug
4. Txhim Kho Troweling thiab Kis Tau Zoo
HPMC txhim kho qhov nplaum du thiab sib xws, ua rau kev nthuav dav yooj yim dua thiab sib xws dua.
- Kev ua tau zoo dua ntawm kev sib tsoo
- Kev tsim cov kab dej huv dua
- Txo kev siv zog ua haujlwm
Hydroxypropyl Methylcellulose Siv Hauv Mortar Systems
Cov qauv mortar - suav nrog masonry mortar, plastering mortar, thiab kho mortar - kuj vam khom rau HPMC kev ua tau zoo.
Cov txiaj ntsig tseem ceeb hauv Mortar
