2. ASTM C920 - Standard Specification rau Elastomeric Joint Sealants: Cov qauv no suav nrog cov kev cai rau ib qho thiab ob lub ntsiab elastomeric sealants siv hauv tsev thiab kev tsim kho.
3. ISO 11600 - Kev tsim vaj tsev - Cov khoom sib koom ua ke: Kev faib tawm thiab cov kev cai rau cov sealants: Cov qauv no qhia txog kev faib thiab cov kev cai rau kev sib koom ua ke sealants siv hauv kev tsim vaj tsev.
4. UL 94 - Tus Qauv rau Kev Ntsuas Cov Hluav Taws Xob ntawm Cov Khoom Siv Yas rau Cov Khoom Siv Hauv Cov Khoom Siv thiab Cov Khoom Siv: Cov qauv no suav nrog kev ntsuas cov nplaim hluav taws xob ntawm cov khoom siv yas siv hauv cov khoom siv thiab cov khoom siv.
5. AAMA 802.3 - Kev yeem Specification rau Chemical Resistant Sealants: Qhov kev qhia tshwj xeeb no suav nrog cov kev cai rau cov tshuaj tiv thaiv cov khoom siv hauv tsev thiab kev tsim kho.
Nov yog cov kauj ruam dav dav rau kev thov cov sealant:
1. Npaj qhov chaw: Qhov saum npoo yuav tsum huv, qhuav, thiab tsis muaj kab mob, xws li roj, plua plav, lossis cov khib nyiab.Siv cov tshuaj ntxuav kom tsim nyog kom tshem tawm cov av lossis cov seem.
2. Nruab tus pas nrig backer: Nruab ib tus pas nrig backer haum rau qhov tob thiab dav ntawm qhov sib koom ua ke.Qhov no yuav pab xyuas kom meej qhov tob sealant thiab muab lub foob zoo dua.
3. Txiav lub nozzle: Txiav lub nozzle ntawm lub sealant cartridge mus rau qhov xav tau loj ntawm lub kaum sab xis 45-degree.
4. Siv lub sealant: Siv cov sealant rau qhov sib koom ua ke hauv cov hlaws txuas ntxiv thiab tsis sib xws.Siv lub sealant nrog lub cuab yeej tsim nyog los xyuas kom meej qhov du thiab txawm tiav.
5. Tso cai rau lub sealant kho: DOWSIL™ SJ268 Silicone Structural Sealant kho nyob rau hauv chav tsev kub los ntawm reacting nrog ya raws nyob rau hauv cov huab cua.Lub sijhawm kho nws txawv nyob ntawm qhov kub, av noo, thiab qhov sib koom ua ke, tab sis feem ntau yog nyob ntawm 7 txog 14 hnub.
6. Ntxuav: Ntxuav cov khoom siv ntau dhau ua ntej nws kho, siv cov tshuaj ntxuav kom haum.
Nov yog qee qhov kev pom zoo los ua ke rau cov sealant no:
1. Lub sealant yuav tsum tau siv rau qhov chaw huv, qhuav, thiab suab nrov.Cov chaw yuav tsum tsis pub muaj kab mob, xws li roj, plua plav, lossis khib nyiab.
2. Kev pom zoo tsim kev sib koom ua ke yuav tsum tau ua raws li txhawm rau txhawm rau txhawm rau txhawm rau qhov tob tob thiab muaj peev xwm txav tau txaus.
3. Kev sib koom ua ke yuav tsum tau tsim kom muaj qhov tsawg kawg nkaus ntawm 25% kev txav mus los hauv cov sealant.
4. Qhov kub thiab txias thaum lub sij hawm thov yuav tsum nyob nruab nrab ntawm 5 ° C mus rau 40 ° C (41 ° F mus rau 104 ° F) kom pom tau qhov zoo.
5. Qhov txheeb ze av noo thaum lub sij hawm thov yuav tsum qis dua 80% kom tsis txhob ya raws los ntawm kev cuam tshuam cov txheej txheem kho.
