(3) Expansion performance testing (tshwj xeeb yog tsim los rau kev nthuav dej)
Volume expansion rate: Tus nqi nthuav dav yog ntsuas ntawm qhov sib txawv immersion lub sij hawm ntawm 24h, 72h, thiab 168h, thiab muab faib ua theem xws li Ntau dua lossis sib npaug rau 150%, Ntau dua lossis sib npaug rau 220%, thiab Ntau dua lossis sib npaug li 300% raws li tus qauv.
Rov ua dua qhov kev ua tau zoo: Kev tuav tus nqi ntawm kev nthuav dav tom qab ntau lub voj voog ntub dej qhuav tau raug ntsuas kom ntev - lub sijhawm ruaj khov.
Expansion siab: Ntsuas lub siab sab nraud tsim thaum ntsib kev nthuav dav dej kom paub tseeb tias cov dej tsis zoo.

(4) Durability thiab ib puag ncig adaptability kuaj
Cov huab cua kub laus: Kev ua tau zoo tuav tus nqi (lub zog tensile, elongation, expansion ratio) ntawm 70℃/ 100 degree.
Ozone aging: tiv thaiv ozone cracking nyob rau hauv static stretching, haum rau sab nraum zoov thiab hnyav ib puag ncig.
Tsis tshua muaj kub yooj yooj yim: Tsis muaj kab nrib pleb thaum khoov ntawm -20℃/-30 degree, ntsuas qhov hloov pauv ntawm qhov kub thiab txias kev siv.
Tshuaj tiv thaiv kab mob: acid thiab alkali tsis kam, ntsev dej tsis kam, av nkos, haus dej tsis kam, dej phwj tuaj, thiab lwm yam khoom.
ntsev tsuag corrosion: Corrosion resistance testing metal accessories (yog muaj).
Thaum tshav kub kub tsis kam: Tsis muaj ntws los yog softening ntawm 80 degree, haum rau kev tsim kho qhov kub thiab txias.

(5) Sealing thiab kev ntsuas dej tsis zoo
Los tiv thaiv lub siab: Txiav txim siab lub peev xwm sib khi ntawm cov dej ntws hauv qab dej siab, feem ntau xav tau ntau dua lossis sib npaug rau 0.3MPa.
Kev ntsuam xyuas hydrostatic siab: Tsis muaj qhov xau nyob rau hauv lub siab nruam los xyuas qhov tseeb ntawm cov dej tsis zoo.
Tus nqi nqus dej: Ntsuas cov dej nqus cov yam ntxwv ntawm cov khoom tsis nthuav dav kom tsis txhob muaj dej nqus dej ntau cuam tshuam rau kev ua haujlwm.

(6) Kev ntsuas kev ua haujlwm tshwj xeeb
Putty hom waterstop: sag, operable lub sij hawm, curing ceev nrhiav kom tau.
Grouting yeeb nkab waterstop: kuaj rau grouting smoothness, sealing kev ntseeg tau, thiab rub- tawm tsis kam.
Nplaim hluav taws xob ua haujlwm: Kev ntsuam xyuas ntawm qhov kev ua tau zoo ntawm kev sib tsoo ntawm cov dej nres siv rau lub sijhawm tshwj xeeb.
