HPMC kev tsim kho yog dab tsi?

HPMC kev tsim kho yog hais txog kev siv hydroxypropyl methylcellulose (HPMC) hauv kev tsim kho kev lag luam. HPMC yog ib hom cellulose ether uas feem ntau siv los ua cov thickener, binder, thiab zaj duab xis-yav dhau los hauv ntau yam kev siv, xws li cov nplaum nplaum, grouts, mortars, renders, thiab plasters.

Hauv kev tsim kho, HPMC feem ntau yog siv los ua ib qho ntxiv hauv cov khoom siv cement los txhim kho lawv cov khoom thiab kev ua haujlwm. Piv txwv li, nws tuaj yeem txhim kho kev ua haujlwm, dej tuav, adhesion, thiab sag kuj ntawm cov khoom.

HPMC kuj tseem siv rau hauv kev tsim cov tshuaj khib nyiab qhuav, uas yog cov hmoov sib xyaw ua ntej uas tsuas yog xav tau cov dej ntxiv rau ntawm qhov chaw. Cov khib nyiab qhuav yog siv dav hauv kev tsim kho rau ntau yam kev siv, xws li pobzeb kho, plastering, thiab screeding. HPMC yog ib qho tseem ceeb muaj nyob rau hauv qhuav-mix mortars, raws li nws pab txhim kho kev ua hauj lwm, adhesion, thiab sib xws ntawm cov khoom.

HPMC kev tsim kho yog ib feem tseem ceeb ntawm kev tsim kho niaj hnub no, vim nws pab txhim kho qhov zoo, ua haujlwm zoo, thiab ua haujlwm ntev ntawm cov khoom siv thiab cov tshuab.
