JINJI ® HPMC siv hauv Self-leveling
Self-leveling Compounds yog cov tshuaj sib tov siv los ua kom cov pob zeb tsis sib xws lossis cov plag tsev ntoo. Lawv yog tsim los ntawm cov cement, xuab zeb, fillers, thiab hloov los ntawm ntau yam additives xws li cellulose ethers, plasticizers, defoamers, stabilizers, thiab redispersible hmoov. Raws li cov khoom ntws, nws tus kheej-leveling thiab nws tus kheej smoothing khoom, nws tus kheej leveling tebchaw tuaj yeem tsim lub tiaj tus, du, thiab tawv tawv uas muaj zog compressive zoo heev.
Qhov sib ntxiv ntawm HPMC tuaj yeem txhim kho cov khoom hauv qab no hauv kev siv tus kheej-leveling compounds:
Flowability
Raws li tus kheej-leveling mortar, fluidity yog ib qho ntawm cov cim tseem ceeb los ntsuas qhov kev ua tau zoo ntawm tus kheej. Raws li qhov kev pom zoo ntawm kev ua kom ntseeg tau cov kev cai ntawm mortar muaj pes tsawg leeg, fluidity ntawm mortar tuaj yeem hloov kho los ntawm kev hloov cov ntsiab lus ntawm fiber ntau HPMC. Txawm li cas los xij, cov ntsiab lus siab dhau lawm yuav txo qhov fluidity ntawm mortar, yog li tus nqi ntawm cellulose ether yuav tsum tau tswj nyob rau hauv qhov tsim nyog ntau yam.
Kev tuav dej
Mortar dej tuav yog ib qho tseem ceeb qhia txog kev ruaj ntseg ntawm cov khoom sab hauv ntawm cov cement mortar tshiab. Txhawm rau ua kom cov dej ntws tawm ntawm cov khoom siv gel tag nrho ua tiav, qhov tsim nyog ntawm cellulose ether tuaj yeem khaws cov dej hauv mortar rau lub sijhawm ntev. Feem ntau, cov dej tuav ntawm cov slurry nce nrog nce ntawm cellulose ether cov ntsiab lus. Cov dej tuav ntawm cellulose ether tuaj yeem tiv thaiv lub substrate los ntawm absorbing dej ntau dhau sai heev thiab cuam tshuam cov dej evaporation, yog li xyuas kom meej tias ib puag ncig slurry muab dej txaus rau cement hydration. Tsis tas li ntawd, viscosity ntawm cellulose ether kuj tseem muaj txiaj ntsig zoo rau cov dej khaws cia ntawm cov tshuaj khib nyiab. Qhov siab dua qhov viscosity, qhov dej tuav tau zoo dua.
Teem sijhawm
HPMC muaj qhov cuam tshuam qeeb ntawm cov tshuaj khib nyiab. Nrog rau qhov nce ntawm cellulose ether cov ntsiab lus, lub sij hawm teem ntawm mortar yog ntev. Cov nyhuv retarding ntawm cellulose ether ntawm cov cement slurry feem ntau yog nyob ntawm qhov kev hloov pauv ntawm pawg alkyl, uas tsis cuam tshuam rau nws qhov hnyav molecular. Qhov qis dua qhov kev hloov pauv ntawm alkyl, qhov siab dua cov ntsiab lus hydroxyl, qhov pom tseeb dua cov nyhuv retarding. Thiab qhov siab dua cov ntsiab lus ntawm cellulose ether, qhov pom tseeb dua cov nyhuv retarding ntawm cov zaj duab xis sib xyaw rau thaum ntxov hydration ntawm cement. Yog li ntawd, qhov tseem ceeb tshaj qhov cuam tshuam retarding yog.
Self-leveling mortar tuaj yeem tso siab rau nws tus kheej qhov hnyav los ua ib lub tiaj tiaj, du thiab ruaj khov ntawm lub substrate rau nteg lossis khi lwm cov ntaub ntawv, thaum tso cai rau kev tsim kho kom zoo tshaj qhov chaw loj.
