Lub redispersible loojas tau sai sai mus rau hauv emulsion tom qab hu rau qhov pib emulsion, uas yog, ib zaj duab xis tuaj yeem tsim tom qab dej evaporates. Zaj duab xis no muaj siab, huab cua siab tiv taus thiab tiv taus ntau yam adhesion siab mus rau ntau hom. Tsis tas li ntawd, cov hmoov yas looj nrog hydrophobicity tuaj yeem ua lub tshuaj khib muaj cov dej tsis kam ua tau zoo.
Redispersible looj xas yog siv nyob rau hauv:
Sab hauv thiab sab nraud phab ntsa putty, nplais nplaum, lub ntsej muag sab nraud, cov tshuaj khib nyiab sab nraud, tshuab hluav taws xob ua kom qhuav, cug sab nraud tov khoom xyaw. Nyob rau hauv cug, nws yog los txhim kho qhov tsis muaj zog ntawm cov khoom sib xyaw briment zoo thiab ncua cov cem lub zog los tiv thaiv thiab ncua lub kaum xis cug cracks. Txij li cov polymer thiab lub tshuaj khib ua cov qauv kev sib txuas lus, uas ntxiv dag zog rau cov kab ke ntawm cov kab sib txuas thiab thaiv qee qhov hws hauv lub cug. Yog li ntawd, txoj kev hloov kho tshiab tom qab ua kom tawv tawv muaj cov kev ua tau zoo dua li xis. Kev txhim kho zoo.
Lub luag haujlwm ntawm redispersible polymer hmoov nyob rau hauv txug feem ntau yog nyob rau hauv cov hauv qab no:
1 txhim kho lub zog compressive thiab cov zog hloov ntawm cug.
2 Qhov sib ntxiv ntawm cov hmoov yas ntawm cov hmoov av ntawm lub tshuaj khib, yog li txhim kho cov kev sib khib ntawm lub tshuaj khib, thiab tib lub sijhawm muab lub tshuaj khib ua cov nyhuv zoo dispersion nyhuv.
3 Txhim kho cov khoom ua ke ntawm cug cug. Lub tshuab ua kom zoo nkauj rau cov adsorption thiab diffusion ntawm macromolecules ntawm cov nplaum. Nyob rau tib lub sijhawm, cov roj hmab hmoov muaj qee cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua ke nrog cov khoom siv ntawm lub hauv paus thiab cov khoom siv tshiab, yog li kev txhim kho cov kev ua tau zoo ntawm cov khoom siv hauv paus. Adsorption, nws cov kev ua tau zoo tau nce.
4 Txo cov match loj heev ntawm cov tshuaj khib, txhim kho lub peev xwm deformation, thiab txo qhov tshwm sim tawg.
5 Txhim kho txoj kev tua ntawd ua hauj cug cug. Kev txhim kho ntawm cov hnav tsis kam yog tsuas yog vim muaj qee tus qauv ntawm cov roj hmab tau tsim los ntawm cov roj hmab muaj peev xwm los ntawm lub qhov thiab cov kab sib xyaws hauv cov cement cug. Txhim kho cov nplaum ntawm cov phau ntawv mus rau cov khoom noj coaszas, yog li nce cov kev coj tsis kam.
6 muab cov tshuaj khib alkali tsis kam.
7 Txhim Kho Cohesion ntawm lub putty, zoo heev tiv, alkali tsis kam, ua tsis kam, thiab txhim kho lub zog yooj yim.
8. Txhim kho lub waterproofness thiab permeability ntawm putty.
