Kev tshuaj xyuas ntawm Cov Khoom thiab Cov Teeb Meem ntawm Redispersible Latex Powder

Lub redispersible latex hmoov khoom yog cov dej-soluble redispersible hmoov, uas yog ib tug copolymer ntawm ethylene thiab vinyl acetate, thiab siv polyvinyl cawv raws li ib tug tiv thaiv colloid. Vim muaj peev xwm khi tau siab thiab cov khoom tshwj xeeb ntawm cov khoom siv rov ua dua tshiab polymer, xws li: dej tsis kam, kev tsim kho thiab rwb thaiv tsev kub, thiab lwm yam, lawv daim ntawv thov ntau yam dav heev.

Redispersible latex hmoov feem ntau yog siv rau hauv: sab hauv thiab sab nrauv phab ntsa putty hmoov, pobzeb nplaum, pobzeb taw tes tus neeg saib xyuas, qhuav hmoov interface tus neeg saib xyuas, sab nrauv phab ntsa rwb thaiv tsev mortar, self-leveling mortar, kho mortar, hniav mortar, waterproof mortar, thiab lwm yam. mix mortar. tus

Redispersible latex hmoov yog xim ntsuab, ib puag ncig tus phooj ywg, lub tsev txuag hluav taws xob, cov khoom siv ntau lub hom phiaj hmoov zoo, thiab yog ib qho tseem ceeb thiab tseem ceeb ua haujlwm ntxiv rau cov tshuaj khib nyiab qhuav. Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, nce lub zog ntawm mortar, txhim kho lub zog sib txuas ntawm mortar thiab ntau yam substrates, txhim kho qhov yooj thiab ua haujlwm, compressive zog, flexural zog, hnav tsis kam, toughness, adhesion ntawm mortar Relay thiab dej tuav peev xwm, kev tsim kho. Tsis tas li ntawd, hydrophobic latex hmoov tuaj yeem ua rau cov tshuaj khib nyiab tsis zoo.

Lub luag haujlwm ntawm redispersible latex hmoov:

1. Tom qab dispersion, lub redispersible latex hmoov tsim ib zaj duab xis thiab ua raws li ib tug thib ob nplaum los txhim kho cov nyhuv;

2. Cov kev tiv thaiv colloid yog absorbed los ntawm lub mortar system (nws yuav tsis raug puas los ntawm dej tom qab tsim zaj duab xis, los yog "secondary dispersion";

3. Cov zaj duab xis-forming polymer resin yog faib nyob rau hauv tag nrho cov mortar system raws li ib tug reinforcing khoom, yog li ua kom lub cohesion ntawm lub mortar; lub redispersible latex hmoov yog ib hom tshuaj tsuag-qhuav tshwj xeeb emulsion (polymer) ua Powder binder. Cov hmoov no tuaj yeem hloov pauv sai sai los ua ib qho emulsion tom qab sib cuag nrog dej, thiab muaj cov khoom zoo ib yam li thawj emulsion, uas yog, zaj duab xis tuaj yeem tsim tom qab dej evaporates. Cov yeeb yaj kiab no muaj qhov hloov tau yooj yim, huab cua tsis kam thiab ua haujlwm rau ntau yam High adhesion rau substrates.
