Redispersible latex hmoov raws li ib qho tseem ceeb additive ntawm qhuav-mixed mortar

Redispersible latex hmoov yog cov hmoov dispersion ua los ntawm kev hloov pauv polymer emulsion los ntawm kev ziab kom qhuav. Nws muaj cov permeability zoo heev thiab tuaj yeem rov emulsioned rau hauv ib qho chaw ruaj khov polymer emulsion tom qab tso dej. Cov organic chemistry yog raws nraim tib yam li thawj moisturizing lotion. Yog li ntawd, nws tuaj yeem tsim cov hmoov zoo qhuav mortar, yog li txhim kho kev ua haujlwm ntawm cov cement mortar.

Redispersible latex hmoov yog ib qho tseem ceeb ua haujlwm ntxiv rau mortar. Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, nce lub zog ntawm cov cement mortar, txhim kho kev sib raug zoo ntawm cov cement mortar thiab ntau cov laug cam, thiab txhim kho lub zog ntawm cov cement mortar. Softness thiab deformability, tensile lub zog, compressive zog, puas kuj, ductility, adhesion sib xeem khiav thiab dej-locking peev xwm, thiab constructability. Tsis tas li ntawd, ntuj latex hmoov nrog dej repellency tuaj yeem ua rau cov cement mortar muaj cov dej noo zoo.

Txhim kho kev sib koom ua ke ntawm cov cement mortar hauv engineering tsim. Tom qab cov cement mortar freshly sib xyaw nrog ntuj latex hmoov dispersion kua yog tsim, cov ntsiab lus dej yuav maj mam txo nrog kev zom thiab nqus dej los ntawm lub hauv paus, noj cov tshuaj tiv thaiv solidification, thiab evaporation rau huab cua. , cov khoom yog maj mam nce mus, cov nplooj ntawv maj mam plooj, thiab lawv maj mam ua ke nrog ib leeg. Thaum kawg, lub polymer yog demulsified. Tag nrho cov txheej txheem ntawm polymer demulsification yog muab faib ua peb qhov txuas. Nyob rau hauv thawj moisturizing emulsion, cov polymer hais yog nyob rau hauv daim ntawv ntawm Brownian motion. Txav mus ywj pheej, nrog rau cov volatilization ntawm cov dej, kev txav ntawm cov khoom yog ib txwm muaj kev txwv ntau thiab ntau dua, qhov nro ntawm cov dej thiab cov pa txhawb nqa lawv kom sib xyaw ua ke maj mam, theem thib ob, thaum cov khoom pib kov ib leeg, Lub network Zoo li dej volatilizes los ntawm capillaries, thiab lub siab-porous txhawb zog tso tawm rau saum npoo ntawm cov khoom ua rau lub deformation ntawm lub ntuj latex spheres ua rau lawv sib raug zoo, thiab cov dej tshuav nyob rau hauv lub pores, thiab daim nyias nyias yog tej zaum tsim. . Qhov thib peb Cov kauj ruam kawg yog ua kom lub diffusion ntawm polymer molecules (qee zaum hu ua self-adhesiveness) tsim ib zaj duab xis nruam tiag tiag thaum lub sij hawm demulsification txheej txheem.
