RDP/VAE siv hauv Mortars & Skim Coat
JINJI® Re-dispersible Polymer Powder (RDP/VAE) yog cov hmoov dawb-ntws dawb ua los ntawm cov tshuaj tsuag kom qhuav dej tshwj xeeb emulsion. Feem ntau yog ua los ntawm vinyl acetate-ethylene.
Tshwj xeeb nta
- Ntxiv adhesion rau cov substrates sib txawv
- Txhim kho compressive thiab flexural zog
- Kev puas tsuaj zoo dua
- Muaj zog tensile thiab deformation muaj peev xwm
- Txhim khu kev khiav thiab nws tus kheej-leveling zog
- Defoaming zog
- Stabilization tiv thaiv los ntshav thiab sedimentation
Txoj kev thov
1. Rau kev tsim cov khoom sib xyaw qhuav mortars.
Xws li cov nplaum thiab troweling compounds, muab JINJI® RDP nrog rau lwm cov khoom xyaw qhuav hauv cov khoom tsim nyog. Qhov kub thiab txias yuav tsum tsis txhob tso cai kom nce siab heev thaum sib tov vim tias tsis yog cov hmoov polymer dispersible tuaj yeem ua rau agglomerate thiab ua rau tsim cov pob me me ntawm cov resin. Lub mortar yog npaj rau kev siv los ntawm kev ntxiv cov dej pom zoo thiab sib tov mechanically lossis tes. Txij li kev sib tov ntawm tes ua kom muaj zog me me, peb pom zoo kom tso cov tshuaj khib nyiab tshiab rau 5 feeb thiab rov ua dua. Qhov no feem ntau tsis tsim nyog qhov twg cov tshuab tov khoom ua haujlwm. Nws lub hom phiaj yog txhawm rau txhim kho kev sib raug zoo ntawm cov nplais pobzeb nplaum thiab ua kom yooj yim rau kev tsim kho cov pobzeb ceramic.
● Lub redispersible polymer hmoov muaj kev cuam tshuam tseem ceeb ntawm kev sib txuas ntawm cov cement-raws li pobzeb nplaum. Nrog rau qhov nce ntawm RDP hauv cov nplais nplaum sib xyaw, cov dej tsis kam thiab kev laus ntawm cov nplais nplaum yuav nce ntxiv. Ntawm lawv, qhov nce hauv kev laus tiv thaiv yog qhov zoo kawg.
● Tus nqi shrinkage ntawm pobzeb nplaum yuav nce ntxiv nrog rau qhov sib ntxiv ntawm RDP. Tab sis kev koom ua ke ntawm RDP hauv pobzeb nplaum yog qhov zoo rau kev ua haujlwm tag nrho ntawm cov nplais pobzeb nplaum.
● Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho lub peev xwm deformation ntawm cov cement-raws li cov nplaum nplaum. Thaum qhov sib xyaw ntawm RDP hauv cov nplais nplaum yog 2%, nws qhov deformation sab nraud tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qib S1 ntawm tus qauv nplaum; Thaum qhov sib xyaw ntawm RDP hauv cov nplais nplaum yog ntau dua 4%, nws qhov deformation sab nraud tuaj yeem ua tau raws li S2 qib nplaum txheej txheem.
2.For zus tau tej cov Skim Coat / Phab ntsa putty
RDP / VAE sib xyaw nrog dej tuaj yeem tawg sai sai rau hauv emulsion, nws muaj cov yam ntxwv zoo ib yam li thawj emulsion, dej evaporation tuaj yeem tsim ib zaj duab xis, zaj duab xis no muaj kev ywj pheej, huab cua tsis kam thiab siab adhesion rau ntau yam substrates. Qhov no yog qhov tseem ceeb heev los txhim kho cov dej tsis kam thiab permeability ntawm phab ntsa putty.
● RDP txhim kho cov kev ua tau zoo, daim ntawv cog lus lub zog, dej tsis kam thiab kev tsim kho muaj peev xwm ntawm putty.
● Nws tuaj yeem txo qhov tawg thiab chalking ntawm cov hmoov tshwj xeeb los ntawm cov phab ntsa putty lossis putty hmoov.
● Nws tuaj yeem ncua kev pabcuam ntawm lub neej ntawm phab ntsa putty thiab tom qab ntawd txo qhov kev saib xyuas ntawm tus nqi.
● Tsis muaj tshuaj lom thiab tsis muaj kuab lom
