High water retention HPMC rau qhuav-siv mortars

HPMC (Hydroxypropyl Methyl Cellulose) yog ib qho tshuaj ntxiv hauv cov tshuaj khib nyiab qhuav, suav nrog cov nplaum nplaum, cov cement-raws li, thiab lwm yam khoom siv hauv tsev. Nws ua raws li cov dej tuav cov neeg sawv cev thiab cov thickener, txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm mortar.

Txhawm rau txhim kho cov dej khaws cia ntawm cov tshuaj khib nyiab qhuav, koj tuaj yeem xaiv HPMC qib uas muaj peev xwm tuav tau dej siab. Cov qib no feem ntau yog cim nrog tus lej viscosity siab dua. Qhov siab dua qhov viscosity, qhov zoo dua cov dej tuav kev ua haujlwm.

Thaum xaiv HPMC rau kev tuav dej siab hauv cov tshuaj khib nyiab qhuav, xav txog cov hauv qab no:

Viscosity: Nrhiav HPMC qib nrog viscosity siab. Viscosity feem ntau yog qhia hauv cov lej xws li 4,000, 10,000 lossis 20,000 cps (centipoise). Cov qib viscosity siab dua yuav muaj cov dej tuav tau zoo dua.

Particle Size: Xav txog qhov loj me me ntawm HPMC hmoov. Cov khoom me me zoo li muaj qhov sib txawv zoo dua thiab muaj peev xwm tuav dej, yog li ua kom cov dej tuav hauv mortars.

Compatibility: Xyuas kom cov qib HPMC koj xaiv yog sib xws nrog rau lwm cov khoom xyaw ntawm koj qhuav-mix mortar formulation. Nws yuav tsum tau tawg yooj yim thiab sib tov zoo nrog lwm cov khoom xyaw yam tsis muaj kev cuam tshuam rau cov khoom ntawm cov tshuaj khib.

Cov yam ntxwv ntawm daim ntawv thov: Cov khoom sib txawv ntawm cov khoom sib xyaw qhuav tuaj yeem muaj cov kev cai tshwj xeeb rau kev tuav dej. Piv txwv li, cov nplais nplaum yuav xav tau cov dej sib txawv dua li cov cement-based plasters. Thaum xaiv HPMC qib, xav txog cov kev thov tshwj xeeb.

Chaw tsim tshuaj paus cov lus pom zoo: Ua raws li cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo rau cov qib HPMC tsim nyog rau kev tuav dej siab hauv cov khoom sib tov qhuav. Lawv feem ntau muab cov ntaub ntawv cov ntaub ntawv thiab cov lus qhia hauv daim ntawv thov los pab koj txiav txim siab xaiv.

Cov qib HPMC xaiv yuav tsum raug kuaj hauv koj qhov tshwj xeeb qhuav-sib xyaw mortar formulation kom ntseeg tau tias nws ua tau raws li koj qhov kev xav tau khaws cia dej thiab xa cov kev ua tau zoo. Ua qhov kev sim me me thiab ntsuas qhov ua haujlwm tau zoo, lub sijhawm qhib thiab cov khoom sib txuas ntawm cov mortar tuaj yeem pab koj txheeb xyuas qhov ua tau zoo ntawm koj qib HPMC xaiv.
