Rau tus kheej-leveling mortar, HPMC MP400 tsawg viscosity hydroxypropyl methylcellulose, tsawg viscosity thiab siab
Kev siv Hydroxypropyl Methyl Cellulose (HPMC), tshwj xeeb tshaj yog qib qis viscosity zoo li HPMC MP400, nyob rau hauv tus kheej-leveling mortar muaj ntau yam zoo vim nws cov khoom tshwj xeeb. Ntawm no yog cov yam ntxwv tseem ceeb thiab cov txiaj ntsig ntawm kev siv cov viscosity tsawgHPMC MP400nyob rau hauv tus kheej-leveling mortar:
1. Txhim kho kev ua haujlwm:
- Tsawg viscosity: HPMC MP400 yog qib qis viscosity, txhim khu kev ua haujlwm ntawm tus kheej-leveling mortar. Nws tso cai rau kev sib xyaw kom yooj yim, siv, thiab siv cov tshuaj khib nyiab.
2. Kev tuav dej:
- Hydration Control: HPMC pab tswj cov dej ntawm cov cement hais, tiv thaiv dej sai sai. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv tus kheej-leveling mortars kom tswj tau qhov kev xav tau sib xws nyob rau lub sijhawm txuas ntxiv.
3. Txo Sagging thiab Slumping:
- Txhim kho Cohesion: Qhov sib ntxiv ntawm cov viscosity tsawg HPMC pab txhawb kev sib koom ua ke zoo dua qub, txo qhov kev nyiam ntawm cov tshuaj khib kom sag lossis poob. Qhov no yog ib qho tseem ceeb tshwj xeeb hauv kev siv tus kheej-leveling qhov twg kev tswj hwm qhov chaw yog qhov tseem ceeb.
4. Teem sij hawm tswj:
- Cov nyhuv Retardation: HPMC MP400 tuaj yeem muaj qhov cuam tshuam me ntsis ntawm lub sijhawm teeb tsa ntawm lub mortar. Qhov no tuaj yeem muaj txiaj ntsig zoo hauv kev siv tus kheej qib uas xav tau lub sijhawm ua haujlwm ntev dua.
5. Txhim kho Adhesion:
- Adhesive Properties: Tsawg viscosity HPMC pab txhim kho qhov adhesion ntawm tus kheej-leveling mortar rau lub substrate. Qhov no yog qhov tseem ceeb rau kev ua kom muaj kev ruaj khov thiab ruaj khov.
6. Txhim kho Deg tiav:
- Smooth Finish: Kev siv cov viscosity tsawg HPMC pab txhawb rau kev ua tiav ntawm kev ua tiav ntawm du thiab txawm ntog. Nws pab txo qhov tsis zoo ntawm qhov chaw thiab txhim kho tag nrho cov tsos ntawm cov mortar kho.
7. Compatibility nrog Additives:
- Compatibility: Tsawg viscosity HPMC feem ntau yog sib xws nrog ntau yam additives siv nyob rau hauv tus kheej-leveling mortar formulations, xws li cua-entraining agents los yog plasticizers.
8. Optimized Rheological Properties:
- Flow Control: Qhov sib ntxiv ntawm HPMC MP400 optimizes lub rheological zog ntawm tus kheej-leveling mortar, tso cai rau nws ntws yooj yim thiab tus kheej-theem yam tsis muaj viscosity ntau dhau.
9. Dosage Control:
- Dosage Flexibility: Qhov qis viscosity ntawm HPMC MP400 muab qhov yooj yim hauv kev tswj kev noj tshuaj. Qhov no tso cai rau cov kev hloov kho kom tau raws li qhov xav tau mortar sib xws thiab kev ua tau zoo.
10. Quality Assurance:
- Kev Ua Tau Zoo: Siv cov qib qis viscosity xws li HPMC MP400 los ntawm cov chaw tsim khoom muaj npe nrov ua kom zoo ib yam ntawm purity, particle size, thiab lwm yam specifications.
Cov ntsiab lus tseem ceeb:
- Cov lus pom zoo noj: Ua raws li cov lus pom zoo muab los ntawm cov chaw tsim khoom kom ua tiav cov khoom xav tau yam tsis muaj kev cuam tshuam kev ua haujlwm ntawm tus kheej-leveling mortar.
- Kev Ntsuas: Ua cov kev sim kuaj thiab sim ua kom paub tseeb qhov ua tau zoo ntawm HPMC MP400 hauv koj qhov tshwj xeeb ntawm tus kheej-leveling mortar formulation.
- Cov txheej txheem sib xyaw: Ua kom muaj cov txheej txheem sib xyaw kom zoo sib xws kom sib cais HPMC hauv cov tshuaj khib nyiab.
- Curing Conditions: Xav txog kev kho mob, suav nrog qhov kub thiab txias, txhawm rau txhim kho kev ua haujlwm ntawm tus kheej-leveling mortar thaum thiab tom qab siv.
Siv cov viscosity tsawg HPMC MP400 nyob rau hauv tus kheej-leveling mortar formulations muab cov txiaj ntsig ntawm kev txhim kho kev ua haujlwm, dej tuav, adhesion, thiab nto tiav. Nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo sib xyaw HPMC rau hauv kev tsim thiab ua raws li cov kev coj ua zoo tshaj plaws rau kev lees paub zoo thiab kev ua haujlwm zoo. Ib txwm xa mus rau cov ntaub ntawv qhia kev thiab cov txheej txheem muab los ntawm cov chaw tsim khoom rau cov ntaub ntawv tshwj xeeb thiab cov lus pom zoo.
