Khoom thiab Daim Ntawv Thov
Gypsum board tshuab tshuab(tseem hu ua gypsum foaming tus neeg saib xyuas) yog ib qho tshwj xeeb surfactant system siv hauv kev tsim cov gypsum plasterboard los ua kom ruaj khov, zoo ua npuas ncauj hauv gypsum slurry. Kev tswj cov kev taw qhia ntawm huab cua txo cov board ntom ntom thaum tswj lossis txawm tias txhim kho cov khoom siv dag zog.
Txoj Cai Ua Haujlwm
Foam tiam
Thaum lub sij hawm tsim khoom:
- Lub foaming tus neeg sawv cev yog diluted nrog dej.
- Cua yog mechanically nkag mus rau hauv cov tshuaj.
- Lub surfactant txo qhov nro ntawm qhov chaw thiab disperses cua uniformly.
- Ib txheej hluav taws xob ob txheej txheej ntawm cov kua zaj duab xis nto.
- Cov npuas npuas yog qhwv thiab ruaj khov, tsim kom zoo, ntom ntom, thiab ua npuas ncauj.
Qhov no maximizes qhov chaw sib cuag ntawm cov kua thiab roj, kom ruaj khov npuas tsim.
Kev sib tham nrog gypsum
Thaum cov npuas dej sib xyaw nrog gypsum slurry (calcium sulfate hemihydrate):
- Lub foaming tus neeg sawv cev cuam tshuam nrog hydrated gypsum hais.
- Hydrogen bonding thiab intermolecular rog tsim cov saw ib ntus -zoo li cov qauv.
- Steric hindrance tshwm sim, txwv kev loj hlob siv lead ua ntau dhau.
- Cov qauv gypsum lattice ua ntau tswj thiab ua kom zoo dua.
- Gypsum kev ua si yog stimulated.
- Ib lub network-zoo li gypsum skeleton cov ntaub ntawv sai dua.
Qhov kev tswj hwm crystallization no txhim kho cov qauv kev ntseeg siab.
Cov txiaj ntsig tshwm sim hauv Gypsum Board
✔ Txhim kho lub zog - rau - qhov hnyav piv
✔ Txo qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom nti
✔ Txuag cov ntaub ntawv raw (tsawg gypsum noj)
✔ Txhim kho qhov sib xws ntawm cov qauv sab hauv
✔ Txhim kho lub cev muaj zog xws li:
Khoov zog
Nail- tuav peev xwm
Dimensional stability
Kev ua haujlwm thermal rwb thaiv tsev
Kev lag luam tseem ceeb
Los ntawm kev qhia ruaj khov micro- ua npuas ncauj rau hauv gypsum matrix:
- Lub rooj tsavxwm dhau los ua sib dua yam tsis muaj kev txi lub zog.
- Ntau lawm efficiency txhim kho.
- Kev thauj mus los thiab kev teeb tsa raug txo qis.
- Tag nrho cov khoom siv yog optimized.
Cov Lus Qhia Tseem Ceeb ntawm Kev Ua Haujlwm Zoo Gypsum Foaming
- Muaj zog foaming muaj peev xwm
- Fine thiab uniform npuas loj
- Siab ua npuas ncauj stability
- Zoo compatibility nrog gypsum slurry
- Tswj kev teeb tsa kev sib cuam tshuam
- Tsis muaj kev cuam tshuam tsis zoo rau board nto zoo
