Gypsum-based self-leveling yog hom tshiab ntawm cov khoom siv hauv av uas yog ntsuab, ib puag ncig tus phooj ywg thiab high-tech.Los ntawm kev siv cov dej ntws zoo ntawm gypsum-based self-leveling mortar, thaj tsam loj ntawm cov av zoo tuaj yeem tsim nyob rau hauv ib lub sijhawm luv luv.Nws muaj qhov zoo ntawm kev ua haujlwm siab, kev nplij siab zoo, rwb thaiv tsev ya raws, mildew tsis kam, kab tsis kam, thiab lwm yam, thiab yooj yim rau kev tsim thiab ceev kom ciaj sia.Nws yog qhov tsim nyog rau qib theem hauv tsev, xws li qib cushions rau nteg cov ntaub pua plag, hauv pem teb, thiab cov vuas hauv pem teb hauv tsev so, chav ua lag luam, thiab kho kom zoo nkauj hauv tsev.
1. Cov khoom siv cementitious: Cov khoom siv cementitious ntawm gypsum-based self-leveling mortar yog lub tsev zoo gypsum.Cov khoom siv raw rau kev tsim lub tsev gypsum yog cov gypsum ntuj uas muaj calcium sulfate los yog cov khoom lag luam gypsum tom qab pretreatment thiab purification, thiab lub tsev gypsum hmoov uas ua tau raws li lub teb chaws tus qauv yog tau los ntawm calcining ntawm ib tug tsim nyog txheej txheem kub.
2. Active admixtures: ya tshauv, slag hmoov, thiab lwm yam yuav siv tau raws li active admixtures rau tus kheej-leveling cov ntaub ntawv.Lub hom phiaj yog txhawm rau txhim kho particle gradation ntawm cov khoom thiab txhim kho kev ua haujlwm ntawm cov khoom siv tawv.Lub active admixture thiab cov khoom siv cementitious tuaj yeem txhim kho lub compactness thiab tom qab lub zog ntawm cov khoom siv los ntawm cov tshuaj tiv thaiv hydration.
3. Retarder: Lub sijhawm teeb tsa yog qhov tseem ceeb ntawm kev ua tau zoo ntawm cov khoom siv tus kheej.Lub sijhawm luv luv lossis ntev dhau los tsis haum rau kev tsim kho.Lub retarder txhawb kev ua haujlwm ntawm gypsum, kho cov supersaturated crystallization ceev ntawm dihydrate gypsum, thiab ua rau lub sijhawm thiab hardening ntawm tus kheej-leveling cov ntaub ntawv nyob rau hauv ib tug tsim nyog ntau yam.
4. Dej txo tus neeg sawv cev: txhawm rau txhim kho qhov kev cog lus thiab lub zog ntawm cov khoom siv tus kheej, nws yog qhov tsim nyog los txo cov dej-binder piv.Nyob rau hauv cov xwm txheej ntawm kev tswj kom zoo fluidity ntawm tus kheej-leveling cov ntaub ntawv, nws yog tsim nyog los ntxiv cov dej txo cov neeg sawv cev.Cov dej reducers sib haum nrog ntau lub tsev gypsums tuaj yeem siv los ua zawv zawg ntawm cov khoom siv yooj yim, yog li txo cov dej sib tov uas xav tau thiab txhim kho cov qauv ntawm cov khoom siv tawv.
5. Dej tuav tus neeg saib xyuas: Cov khoom siv tus kheej qib yog tsim los ntawm lub hauv paus hauv av, thiab cov thickness ntawm kev tsim kho yog nyias nyias, thiab cov dej tau yooj yim absorbed los ntawm hauv av hauv paus, ua rau cov khoom tsis txaus, tawg ntawm qhov chaw, thiab txo zog.Feem ntau, tsawg-viscosity (tsawg dua 1000)Cellulose Ether (HPMC)yog siv los ua tus neeg saib xyuas dej.Cellulose ether muaj qhov ntub dej zoo, tuav dej thiab ua cov yeeb yaj kiab, kom cov khoom siv tus kheej tsis tuaj yeem los ntshav thiab muaj dej txaus.
6. Defoaming tus neeg saib xyuas: Tus neeg saib xyuas defoaming tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov khoom siv tus kheej, txo cov cua npuas thaum cov khoom tsim, thiab muaj qee yam cuam tshuam rau kev txhim kho lub zog ntawm cov khoom.
