Self-leveling mortar feem ntau yog siv rau kev kho kom zoo nkauj hauv pem teb. Self-leveling muaj fluidity zoo, tsis muaj cracking, tsis hollowing, thiab tuaj yeem tiv thaiv hauv pem teb.
Cov xim muaj xws li ntuj cement grey, liab, ntsuab, thiab lwm yam xim kuj tuaj yeem kho raws li koj nyiam.
Kev tsim kho yog qhov yooj yim, nws tuaj yeem siv tau tom qab ntxiv dej thiab nplawm, thiab nws tuaj yeem sib kis tau sai sai rau hauv av kom tau txais cov qib siab hauv pem teb.

Kev sib xyaw ntawm tus kheej-leveling cement
Self-leveling cement, tseem hu ua self-leveling mortar, yog hydraulically hardened composite khoom ua los ntawm cov cement ua cov khoom siv hauv paus thiab sib xyaw nrog lwm cov ntaub ntawv hloov kho. Qhov uas twb muaj lawm tus kheej-leveling cement mortar muaj ntau yam qauv, tab sis cov muaj pes tsawg leeg yog hais txog tib yam.
Nws feem ntau muaj rau ntawm qhov chaw:
1. Cov khoom siv gelling sib xyaw
Muaj peb hom kev siab alumina cement, zoo tib yam Portland cement, thiab a-hemihydrate gypsum / anhydrite, accounting rau 30% -40%.
2. Mineral muab tub lim
Feem ntau quartz xuab zeb thiab calcium carbonate hmoov, accounting rau 55% -68%.
3. Coagulant regulator
Feem ntau retarder - tartaric acid, coagulant - lithium carbonate thiab superplasticizer - superplasticizer, accounting rau 0.5%.
4. Rheology hloov kho
Feem ntau defoamers thiab stabilizers, accounting rau 0.5%.
5. Cov khoom ua kom zoo dua qub
Feem ntau redispersible polymer hmoov, accounting rau 1% -4%.
6. Dej
Raws li cov qauv yuav tsum tau ntxiv qhov tsim nyog cov dej los ua tus kheej-leveling mortar.

Kev ua tau zoo ntawm tus kheej-leveling cement mortar
Self-leveling cement mortar muaj qee yam yuav tsum tau ua, suav nrog fluidity, slurry stability, compressive zog, thiab lwm yam.:
1. Fluidity: Feem ntau, qhov fluidity ntau dua 210 ~ 260mm.
2. Slurry stability: Muab cov slurry sib xyaw rau ntawm lub khob phaj tso rau hauv kab rov tav, thiab saib nws tom qab 20 feeb. Yuav tsum tsis muaj qhov pom tseeb los ntshav, stratification, cais, thiab bubbling.
3. Compressive zog: Lub zog compressive ntawm cov cement mortar nto txheej yog siab tshaj 15MPa, thiab lub zog compressive ntawm cov cement pob zeb txheej yog siab dua 20MPa.
4. Flexural zog: Lub zog flexural ntawm kev lag luam tus kheej-leveling cement mortar yuav tsum siab dua 6Mpa.
5. Lub sijhawm coagulation: Tom qab paub meej tias cov slurry yog nplawm tusyees, xyuas kom meej tias nws lub sijhawm siv ntau tshaj 40 feeb, thiab kev ua haujlwm yuav tsis cuam tshuam.
6. Kev cuam tshuam kev cuam tshuam: tus kheej-leveling cement mortar yuav tsum muaj peev xwm tiv taus kev sib tsoo ntawm tib neeg lub cev thiab thauj cov khoom hauv ib txwm muaj kev khiav tsheb, thiab cov kev cuam tshuam hauv av yog ntau dua lossis sib npaug li 4 joules.
7. Bonding tensile lub zog rau lub hauv paus txheej: Lub zog tensile lub zog ntawm tus kheej-leveling khoom ntawm cov cement pem teb yog feem ntau siab dua 0.8 MPa.
Nta ntawm tus kheej-leveling mortar:
1. Nws muaj fluidity zoo, kis tusyees, thiab tuaj yeem ntws zoo rau hauv qhov khoob ntawm cov kav dej hauv pem teb.
2. Lub hardened self-leveling mortar yog tusyees faib thiab muaj peev xwm tiv thaiv kev sib cais zoo.
3. Tus qauv ntom ntawm tus kheej colleling yog kom zoo rau lub kev sib dhos nce mus ntawm tshav kub, uas tuaj yeem xyuas kom cov cua sov zoo.
4. Lub zog muaj zog, nrawm nrawm, feem ntau 1-2 hnub tuaj yeem siv tau.
5. Lub shrinkage tus nqi yog tsawg heev, thiab nws tsis yooj yim rau tawg, delaminate thiab hollow.
Kev siv tus kheej-leveling mortar:
Self-leveling mortar feem ntau yog siv rau hauv pem teb kho kom zoo nkauj ntawm cov tsev niaj hnub. Nws muaj cov yam ntxwv ntawm siab flatness, zoo fluidity thiab tsis muaj cracking, thiab yog hlub los ntawm feem ntau ntawm cov tswv.
Tus kheej-leveling pem teb yog seamless raws li tag nrho, nws tus kheej-leveling, hauv av yog tiaj tus, du thiab zoo nkauj; dustproof, waterproof, yooj yim los ntxuav; zoo corrosion kuj, acid thiab alkali tsis kam, hnav tsis kam, compression tsis kam, cuam tshuam tsis kam, thiab qee yam elasticity.
Kev siv thiab kev siv scenarios:
1. Cement self-leveling yog siv los ua lub hauv paus qib siab rau cov plag tsev epoxy, polyurethane pem teb, PVC coils, ntawv, roj hmab hauv pem teb, cov khoom ntoo, thiab pob zeb diamond daim hlau.
2. Cement self-leveling yog cov khoom siv hauv tsev tiaj tus uas yuav tsum tau siv rau kev tso cov PVC coils ntawm cov plag tsev nyob ntsiag to thiab plua plav pov thawj ntawm cov tsev kho mob niaj hnub no.
3. Cement self-leveling kuj tseem siv rau hauv cov chav huv si, cov plag tsev tsis muaj plua plav, cov plag tsev tawv, thiab cov plag tsev antistatic hauv cov khoom noj khoom haus, cov chaw muag tshuaj, thiab cov khoom siv hluav taws xob precision.
4. Polyurethane elastic pem teb txheej txheej rau kindergartens, tennis courts, thiab lwm yam. Raws li lub hauv paus txheej ntawm acid thiab alkali resistant pem teb ntawm industrial cog thiab hnav-resistant pem teb. Neeg hlau khiav nto. Pav ca puag rau kev kho kom zoo nkauj hauv tsev.
5. Ntau qhov chaw dav dav yog kev sib koom ua ke thiab qib. Xws li lub tshav dav hlau halls, tsev so loj, hypermarkets, department khw, lub rooj sib tham halls, exhibitions, halls, chaw nres tsheb, thiab lwm yam. tuaj yeem ua tiav cov plag tsev siab ceev ceev.
