HydroxyPropyyl Methylcellulose(HPMC)yog cov cuab yeej siv hluav taws xob polymer tau siv hauv kev tsim kho los hloov cov khoom ntawm cov khoom noj qabent-raws li cov ntaub ntawv. Nws cov tsoom thawj suav nrog kev txhim kho cov haujlwm ua haujlwm, kev ua kom dej, cov nplaum thiab sijhawm teeb tsa. Qhov sib piv ntawm Kimacell® Tus lej Bement yog qhov ntsuas tseem ceeb uas cuam tshuam qhov kev ua tau zoo ntawm kev sib xyaw.
Cov Lus Dav Ntawm Hpmc kom xis mas piv
| HPMC kom xis mas piv (%) | Nyhuv rau cov khoom | Cov Ntawv Thov |
| 0.1 - 0.3% | Kev txhim kho me ntsis hauv kev tuav pov hwm thiab ua haujlwm. Tsawg heev rau lub zog. | General Masonry Mortars. |
| 0.4 - 0.6% | Txhim kho cov nplaum, cov dej tuav tseg, thiab xwm yeem. Me ntsis ncua sij hawm. | Pobzeb Cov Khoom nplaum, Yooj Yim Plastering. |
| 0.7 - 1.0% | Qhov nce loj hauv kev txuag dej thiab kev ua haujlwm. Ncua nyob rau hauv teeb tsa lub sijhawm yuav ua tau pom. | Nyias-txaj nplaum, kev sib txuas lus tus kheej. |
| 1.1 - 1.5% | Dej siab ceev. Cim kev txhim kho hauv kev ua haujlwm, cohesion, thiab adhesion. Teeb tsa qeeb tshwm sim. | Skim tsho tiv no, muaj kev tuag siab. |
| > 1.5% | Kev ua kom ntau dhau thiab qeeb qeeb qeeb thiab tseem qeeb qeeb hauv kev teeb tsa. Kev pheej hmoo ntawm txo cov tshuab siv zog. | Cov npe tshwj xeeb uas yuav tsum tau siv sijhawm tshwj xeeb. |
Cov ncauj lus kom ntxaws piav qhia ntawm cov yuam sij
Tsawg Piv (0.1 - 0.3%)
Qhov Zoo:
Txhim kho cov khoom yooj yim uas tsis muaj cov qauv hloov kho kom zoo.
Haum rau cov kev cai hloov pauv kev cai ua ke nrog qhov tsawg kawg nkaus uas xav tau kev hloov kho.
Txwv:
Txwv kev cuam tshuam rau ntawm cov dej khaws cia hauv cov pa roj av.
Kev Ntsuas Nruab Nrab (0.6%)
Qhov Zoo:
Sib npaug kev tuav thiab ua haujlwm rau cov ntawv thov ntau dua.
Qhov zoo tagnrho rau cov xwm txheej uas yuav tsum tau ua kom zoo dua adhesion rau substrates.
Txwv:
Cov chaw me me qeeb tuaj yeem tshwm sim, tab sis tswj tau ib txwm muaj.
Cov Lus Sib Ntaus Siab (0.5 - 1.5%)
Qhov Zoo:
Muab cov tshuaj kom zoo tshaj plaws thiab cov ntawv thov du, txo kom qhuav shrinkage.
Nyiam rau nyias-txheej ntaub ntawv thov xav tau precision.
Txwv:
Yuav tsum tau tswj hwm kom tsis txhob muaj kev teeb tsa ntau dhau, uas tuaj yeem cuam tshuam sijhawm sijhawm.
Piv (> 1.5%)
Qhov Zoo:
Pab txhawb cov dej siab heev thiab lub sijhawm qhib lub sijhawm.
Pab tau rau niche lossis huab huab ib puag ncig.
Txwv:
Tuaj yeem sib cav sib ceg rau cov neeg kho mob lub zog ntawm cov khoom kawg yog tias tsis ua tib zoo engineered.
Qhov Tseem Ceeb cuam tshuam rau kev xaiv
Hom ntawv thov:
Cov nplaum:Yuav tsum muaj kev txheeb xyuas ntau dua rau kev txhim kho txoj hlua khi kom muaj zog thiab tiv thaiv qeeb qeeb.
Neeg tuag:Kev ntsuas sib luag kom pom tseeb lub sijhawm ua haujlwm zoo thiab txaus.
Ib puag ncig cov xwm txheej:
Cov mob siab los yog cua hlob feem ntau xav tau ntau dua HPMC sib npaug rau cov dej kom zoo dua.
Maas Hom:
Cov kev hloov pauv hloov pauv sib txawv yuav ua rau muaj sib txawv nrog Kimacell®hpmc, muaj feem cuam tshuam kev pom kev zoo.
Additive Compatibility:
Kev sib cuam tshuam nrog lwm cov tshuaj ntxiv (piv txwv li, cov neeg rov qab lossis cov nrawm) yuav tsum tau txiav txim siab.
Siv txoj cai piv ntawmHPMCTxhawm rau kom cov ntseeg tau yog qhov tseem ceeb rau kev ua tau zoo hauv cov ntaub ntawv tsim kho. Thaum cov kev sib piv tsawg dua muab cov kev txhim kho ntawm cov kev txhim kho, ntau dua kev sib piv tau ua rau cov ntawv thov tshwj xeeb. Siv ntau dhau, txawm li cas los xij, tuaj yeem ua rau txo qis dua lub sijhawm muaj zog thiab ncua sij hawm, tsim nyog ua kom ze. Kev tshawb fawb ntxiv thiab kev kuaj ntawm sab hauv yog pom zoo rau cov haujlwm tshwj xeeb kom ntseeg tau qhov txiaj ntsig zoo tshaj plaws.
