Kev siv HPMC hauv cov hmoov qhuav mortar

HPMC (Hydroxypropyl Methyl Cellulose) feem ntau yog siv rau hauv cov tshuaj khib nyiab qhuav vim nws muaj txiaj ntsig zoo.Cov hauv qab no yog qee qhov kev siv tshwj xeeb ntawm HPMC hauv cov hmoov qhuav mortar:

Kev tuav dej: HPMC ua tus neeg saib xyuas dej hauv cov tshuaj khib nyiab qhuav.Nws absorbs thiab khaws cov dej noo, tiv thaiv evaporation sai thaum kho.Cov cuab yeej no pab txhim kho kev ua haujlwm, ua kom lub sijhawm qhib thiab txhim kho kev ua haujlwm tag nrho ntawm cov mortar.

Kev ua haujlwm thiab kev sib kis tau: HPMC ua raws li kev hloov kho rheology txhawm rau txhim kho kev ua haujlwm thiab kis tau ntawm cov hmoov qhuav mortar.Nws muaj cov nyhuv lubricating, ua kom yooj yim rau kev sib tov, thov thiab kis cov tshuaj khib.Qhov no txhim kho lub zog ntawm daim ntawv cog lus thiab adhesion ntawm mortar rau ntau yam substrates.

Anti-Sag thiab Anti-Slip: HPMC pab txo qis sag thiab slippage ntawm mortar qhuav thaum lub sij hawm ntsug los yog overhead tsim.Nws ua rau kom cov viscosity thiab cohesion ntawm lub mortar thiab tiv thaiv lub mortar los ntawm zawv zawg los yog sagging ua ntej teeb.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau kev teeb tsa ntsug, xws li cov nplais nplaum lossis cov ntawv thov plastering.

Txhim kho Bond Strength: HPMC txhim kho qhov adhesion thiab daim ntawv cog lus lub zog ntawm cov mortars qhuav rau ntau qhov chaw, suav nrog pob zeb, masonry thiab pobzeb.Nws tsim ib zaj duab xis nyias ntawm qhov chaw ntawm lub substrate, txhawb kev adhesion zoo dua thiab txo qhov kev pheej hmoo ntawm tev lossis delamination.

Crack resistance thiab durability: HPMC txhim kho lub zuag qhia tag nrho durability thiab tawg tsis kam ntawm qhuav mix mortar.Nws pab txo qis shrinkage thiab minimizes tawg tsim thaum ziab thiab kho.Qhov no txhim khu kev ua haujlwm ntev thiab kev ua haujlwm ruaj khov ntawm cov mortar.

Compatibility nrog rau lwm yam additives: HPMC yog sib xws nrog ntau yam ntawm lwm yam additives siv nyob rau hauv qhuav mortar formulations, xws li plasticizers, air-entraining agents thiab dispersants.Nws tuaj yeem yooj yim ua ke nrog cov additives no kom ua tiav cov yam ntxwv ua tau zoo thiab txhim kho cov qauv tsim.

Nws yog ib qho tsim nyog sau cia tias qhov tshwj xeeb ntawm HPMC siv rau hauv cov tshuaj khib nyiab qhuav tuaj yeem sib txawv nyob ntawm seb yam xws li qhov xav tau sib xws, daim ntawv thov txheej txheem thiab ib puag ncig.Cov neeg tsim khoom thiab cov neeg muag khoom feem ntau muab cov lus qhia thiab cov lus pom zoo txog kev siv thiab kev siv ntawm HPMC hauv cov ntawv siv tshuaj khib nyiab qhuav.
