HPMC yog ib qho uas tsis yog-ionic, dej soluble cellulose ether uas tsim cov yeeb yaj kiab, dej-retention, stability, adhesiveness, tshwj xeeb tshaj yog dav siv rau kev tsim cov ntaub ntawv vim nws tau xaiv los txhim kho adhesion, dej tuav, thiab lubrication, ntsws thiab tawg kuj. Hloov kho cellulose ethers txhim kho ntawm qhov slippage, nkig tsis kam rau siab thiab tensile pw ua ke. Yog li ntawd, rau cov cement thiab plaster raws li motors, yuav yog koj qhov kev xaiv zoo tshaj plaws. Nws yog cov hmoov dawb los yog dawb dawb, tsis muaj tshuaj lom tsis muaj kuab lom, thiab yooj yim soluble hauv dej kub lossis txias.
HPMC kuj siv rau ceramics, luam yeeb thiab detergents, thiab lwm yam.
Rau ntau txoj kev ntawm binder, Youngcel tuaj yeem muab ntau yam khoom siv cellulose ether kom yooj yim ua tau raws li qhov xav tau sib txawv.
- Kev ua haujlwm siab heev
- Kev xav tau dej siab thiab tso zis ntau
- Zoo heev sag resistance
- Lub sijhawm qhib ntev
- Yooj yim nthuav tawm thiab tsis txhob lo rau riam
