Qhov ntsuas kub haum rau Waterproof txheej

Waterproof txheej xaiv cov yam ntxwv ntawm kev daws teeb meem, nano-ceramic hollow hais, silica alumina fibers, txhua yam ntawm cov khoom siv los ua cov khoom siv tseem ceeb, thermal conductivity tsuas yog 0.03W / mK, tuaj yeem tiv thaiv cov hluav taws xob tiv thaiv hluav taws xob thiab hluav taws xob zoo.

Nyob rau lub caij ntuj sov, ntawm qhov kub ntawm ntau tshaj 40 ℃, nws yuav tsis tsim nyog ua dej tsis zoo, vim li no:

1. queous los yog hnyav-raws li waterproof txheej siv nyob rau hauv kub kub tej yam kev mob yuav sai sai thickens, ua priming nyuaj, cuam tshuam rau kev tsim kho zoo; Tsis tas li ntawd, nyob rau hauv cov txheej txheem ua yeeb yaj kiab, qhov kub siab tshwm sim los ntawm txheej txheej ntawm cov dej noo los yog evaporation sai ntawm cov kuab tshuaj, thaum cov dej hauv qab los yog hnyav hauv cov xim tsis txaus volatile, filming tab sis nyuaj. Nyob rau hauv cov ntaub ntawv ntawm undesirable deposition txuas ntxiv kev tsim kho, cov ya raws embedded nyob rau hauv lub txheej, qhov tshwm sim ntawm blistering, delamination, thaum lub txheej zaj duab xis yog yooj yim los tsim shrinkage tawg.
2. cov txheej txheej reactive yog ob yam tshuaj tiv thaiv cov tshuaj tiv thaiv kub kub ceev, lub sijhawm kho luv luv, kev tsim kho lub sijhawm, kev ua haujlwm ntawm kev tsim kho nyuaj heev, ua rau muaj peev xwm ua kom muaj teeb meem zoo.
3. mortar, waterproofing tus neeg sawv cev nyob rau hauv tus txheej txheem ntawm kev tsim cov waterproof txheej, yog hais tias qhov kub thiab txias yog siab dhau lawm, cov cement nyob rau hauv tus txheej txheem ntawm hydration dej molecules volatilized sai heev, nws yuav tsis tau tag nrho hydrated, curing yog tsis tiav waterproof txheej, cov txiaj ntsig tshwm sim. los ntawm cov xuab zeb tawm hmoov, los ntawm daim tawv nqaij thiab lwm yam teeb meem.
4. Cov huab cua kub hauv kev tsim kho cov neeg ua haujlwm ua rau muaj qhov tshwm sim ntawm kev qaug zog, lub cev qhuav dej, kub cev, hnyav ua rau muaj kev phom sij rau kev nyab xeeb ntawm lub neej thiab kev noj qab haus huv ntawm cov neeg ua haujlwm.
