Lub luag hauj lwm dab tsi yog redispersible roj hmab hmoov ua si hauv gypsum-raws li mortar? A: lub luag hauj lwm ntawm re-dispersible latex hmoov nyob rau hauv ntub gypsum slurry: 1 kev tsim kho kev ua tau zoo; 2 kev ua haujlwm ntws; 3 thixotropy thiab anti-sag; 4 hloov cohesion; 5 ncua sijhawm qhib; 6 txhim khu kev tuav dej.
Cov nyhuv ntawmHigh Flexible Redispersible PowderTom qab gypsum curing: 1 nce tensile zog (ntxiv cov nplaum nyob rau hauv gypsum system); 2 nce bending zog; 3 txo elastic modulus; 4 nce deformability; 5 nce cov khoom ntom ntom; 6 txhawm rau txhim kho kev hnav tsis kam, 7 txhawm rau txhim kho kev sib koom ua ke, 8 txhawm rau txo cov khoom siv dej nqus, 9 ua kom cov khoom siv hydrophobic (ntxiv hydrophobic roj hmab hmoov).
Dab tsi yog cov gypsum adhesives?
Teb: cellulose ether water-retaining agent muaj kev ua haujlwm ntawm kev ua kom cov adhesion ntawm gypsum thiab lub hauv paus, xws li yuav tsum tau khi gypsum board, gypsum block, gypsum hniav kab ntxiv rau ntxiv cellulose ether water-retaining agent, koj kuj yuav tsum tau ntxiv. Qee cov organic adhesives, dispersible latex hmoov, polyvinyl cawv roj hmab hmoov, carboxymethyl cellulose (CMC), hloov cov hmoov txhuv nplej siab, polyvinyl acetate (dawb kua nplaum), yas acetate-vinyl copolymer emulsion, thiab lwm yam.
Yuav ua li cas xaiv cov nplaum rau gypsum?
A: polyvinyl cawv thiab carboxymethyl cellulose tsis tshua muaj dej, tab sis raws li gypsum tsuas yog siv sab hauv tsev ua cov nplaum,Redispersible Latex Powdercov kev xav tau rau cov dej tsis zoo thiab cov kav ntev tsis siab, yog li nws yog kev lag luam ntau dua los siv polyvinyl cawv thiab carboxymethyl cellulose kom muaj kev sib raug zoo. Cov polyvinyl acetate thiab vinyl acetate-vinyl copolymer emulsion muaj adhesion zoo, dej tsis kam thiab kav ntev, tab sis tus nqi ntawm polyvinyl cawv yog loj dua li ntawm gypsum, thiab tus nqi siab dua.
