5 Lub Hom Phiaj Zoo Rau Cov Txheej Txheem Dej Tsis Zoo yog qhov tseem ceeb
Jun 28, 2022
Muaj ntau ntau hom waterproof txheej, tab sis waterproof coatings tag nrho cov muaj ib yam uas zoo sib xws. Thaum siv lossis sim, muaj 5 lub hom phiaj tseem ceeb. Raws li cov ntaub ntawv muab los ntawm Hubei Sancheng Weiye Experimental Testing Center, tsib lub hom phiaj tseem ceeb ntawm cov dej tsis zoo yog raws li hauv qab no:
1. Khoom ntsiab lus:
Hubei Sancheng Albert tsis yog cliché ntawm no. Lub ntsiab zaj duab xis-tsim tshuaj ntawm ntau yam waterproof txheej, raws li cov yam ntxwv ntawm ntau yam waterproof txheej, muab tso rau pem hauv ntej cov ntaub ntawv uas yuav tsum tau ntawm ntau yam waterproof txheej. Yog tias cov ntsiab lus ntawm cov khoom tsawg dhau, nws yog qhov nyuaj los xyuas kom meej qhov zoo ntawm cov yeeb yaj kiab txheej.
2. Thaum tshav kub kub tsis kam:
Nyob rau hauv qhov kub siab tshaj plaws nyob rau lub caij ntuj sov, qhov kub ntawm lub ru tsev saum npoo tuaj yeem ncav cuag 70 degrees Celsius. Yog hais tias lub tshav kub tsis kam ntawm cov txheej yog tsawg dua 80 degrees Celsius thiab tsis tuaj yeem kav ntev li 5 teev, cov zaj duab xis txheej yuav ntws, hlwv thiab swb.
3. Tsawg kub yooj:
Nyob rau hauv thiaj li yuav ua rau ntau yam waterproof coatings muaj ib tug tej yam cwj pwm ntawm kev tsim kho kub, raws li cov yam ntxwv ntawm ntau yam waterproof txheej, tsis tshua muaj kub yooj yuav tsum tau ntawm ntau yam waterproof txheej yog muab tso rau pem hauv ntej.
4. Extensibility:
Thawj qhov yog ua kom txhua yam ntawm cov txheej txheem dej tsis muaj dej muaj qee yam muaj peev xwm hloov mus rau qhov deformation ntawm cov txheej hauv qab kom ntseeg tau tias cov dej tsis zoo. Raws li cov yam ntxwv ntawm ntau yam waterproof coatings, lub extensibility yuav tsum tau ntawm ntau yam waterproof txheej yog muab tso rau pem hauv ntej.
5. impermeability:
Raws li cov yam ntxwv ntawm ntau yam waterproof coatings, lub impermeability yuav tsum tau ntawm ntau yam waterproof txheej yog muab tso rau pem hauv ntej. Yog tias qhov kev xav tau zoo tuaj yeem ua tau raws li qhov yuav tsum tau ua, yuav tsis muaj qhov xau ncaj qha ntawm cov txheej txheem dej ua tiav.
