Kev Hloov Pauv Kev Nyab Xeeb Hluav Taws hauv Kev Thauj Mus Los Tsheb Ciav Hlau nrog Cov Ntaub Tiv Thaiv Hluav Taws Kub Siab
Thaum cov kev thauj mus los ntawm tsheb ciav hlau txuas ntxiv nthuav dav sai sai, kev ua kom cov neeg caij tsheb muaj kev nyab xeeb thiab kev xis nyob tau dhau los ua qhov kev txhawj xeeb tseem ceeb hauv kev txiav txim siab tsim. Ntawm cov khoom tseem ceeb, cov ntaub ntawv zaum ua lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog thaum muaj xwm txheej ceev xws li hluav taws. Cov ntaub tiv thaiv hluav taws yog qhov tseem ceeb hauv kev thauj mus los ntawm tsheb ciav hlau kom qeeb qeeb qhov kev sib kis ntawm cov nplaim taws, tiv thaiv cov neeg caij tsheb thiab txo qhov kev puas tsuaj.
Cov Ntaub Tiv Thaiv Hluav Taws yog dab tsi?
Cov ntaub tiv hluav taws yog cov ntaub uas tau kho tshwj xeeb uas tsim los tiv taus hluav taws thiab qeeb qeeb qhov kis hluav taws. Cov ntaub no ua tiav lawv cov yam ntxwv tiv taus hluav taws los ntawm kev ntxiv cov tshuaj tiv thaiv hluav taws lossis siv cov xov hluav taws uas tiv taus hluav taws. Lub luag haujlwm tseem ceeb ntawm cov ntaub tiv hluav taws yog txo qhov ceev ntawm kev sib xyaw, txwv tsis pub hluav taws kis mus, thiab txawm tias tua nws tus kheej, yog li txo qhov cuam tshuam ntawm cov xwm txheej hluav taws.
Cov txheej txheem ntawm kev tiv thaiv hluav taws
Cov ntaub thaiv hluav taws ua haujlwm los ntawm ntau txoj hauv kev tseem ceeb:
- Kev ncua sij hawm ntawm cov roj theem:Tso tawm cov pa roj uas tiv thaiv hluav taws uas ua rau cov pa roj uas sib xyaw tau yooj yim yaj, thiab ua rau cov tshuaj tiv thaiv kev sib xyaw tsis ua haujlwm.
- Kev ncua sij hawm ntawm theem condensed:Tsim ib txheej hluav taws xob tiv thaiv rau ntawm qhov chaw ntawm cov khoom, rwb thaiv nws ntawm cua sov thiab oxygen, yog li tiv thaiv kev kub hnyiab ntxiv.
- Kev Cuam Tshuam Kev Sib Pauv Kub:Nqus cov cua sov los ntawm cov tshuaj tiv thaiv endothermic, txo qhov kub ntawm cov khoom thiab nres kev sib xyaw.
Kev faib tawm ntawm Cov Ntaub Tiv Thaiv Hluav Taws
Raws li txoj kev siv cov tshuaj tua hluav taws, cov ntaub no tuaj yeem muab faib ua:
- Cov Ntaub Tiv Thaiv Hluav Taws Tom Qab Kho:Cov tshuaj tiv thaiv hluav taws kub raug siv thaum lub sijhawm ua tiav cov ntaub. Peb cov khoom, TF-211 thiab TF-212, yog cov tshuaj tiv thaiv hluav taws kub zoo tshaj plaws uas siv rau hauv cov txheej txheem txheej tom qab, muab kev tiv thaiv hluav taws kub zoo heev. Cov tshuaj tiv thaiv no tsis muaj halogen, tsis ua rau ib puag ncig puas tsuaj tsim cov pa luam yeeb tsawg thiab tsis muaj cov pa phem thaum lub sijhawm hlawv.
- Cov Ntaub Ntawv Uas Muaj Hluav Taws Kub:Cov tshuaj tiv thaiv hluav taws tau koom ua ke rau hauv cov fibers thaum lub sijhawm tig, ua rau cov fibers lawv tus kheej tiv taus hluav taws.
Kev Soj Ntsuam Kev Ua Haujlwm Tiv Thaiv Hluav Taws
Cov ntaub no ua tau zoo tiv thaiv hluav taws kub los ntawm ntau qhov kev xeem txheem:
- Kev Ntsuas Kub Ntsug (GB / T 5455-2014):Ntsuas tus cwj pwm hlawv ntawm cov khoom siv ntsug; qhov ntev hlawv yuav tsum tsis pub tshaj 150 hli.
- Kev Ntsuas Kub Hnyiab Kab Rov Tav (GB / T 2408-2008):Soj ntsuam qhov kub hnyiab ntawm cov khoom siv kab rov tav; tus nqi yuav tsum yog ≤100mm / feeb.
- Kev Ntsuas Pa oxygen Txwv (LOI) (GB/T 2406-2008):Txheeb xyuas qhov tsawg kawg nkaus ntawm cov pa oxygen uas xav tau los txhawb kev sib xyaw ua ke; LOI yuav tsum yog ≥28%.
Cov Khoom Siv Ua Los Ntawm Cov Npuag Uas Tiv Thaiv Tau Hluav Taws
Cov ntaub uas ua los ntawm cov ntaub uas tiv taus hluav taws muaj feem cuam tshuam rau lawv txoj kev tiv taus hluav taws thiab cov yam ntxwv ntawm lub cev. Cov ntaub ntawv feem ntau muaj xws li:
- Polyester:Muaj kev tiv thaiv kev hnav zoo heev thiab lub zog tensile tab sis muaj kev tiv thaiv hluav taws tsawg.
- Aramid:Muab kev tiv thaiv hluav taws zoo dua thiab kev kam rau siab kub tab sis tus nqi siab dua.
- Paj Rwb Tiv Thaiv Hluav Taws:Ua ke zoo qhov xis nyob nrog kev tiv thaiv hluav taws tab sis tsis muaj kev tiv thaiv kev hnav.
Peb Cov Khoom: TF-211 thiab TF-212
Nyob rau hauv pem hauv ntej ntawm cov thev naus laus zis tiv thaiv hluav taws, peb cov khoom TF-211 thiab TF-212 yog tsim tshwj xeeb rau kev siv rau hauv cov ntaub thauj mus los ntawm tsheb ciav hlau. Cov tshuaj tiv thaiv hluav taws no tsis muaj halogen, zoo rau ib puag ncig tau siv los ntawm cov txheej txheem txheej tom qab, kom ntseeg tau tias cov ntaub tsis yog tsuas yog ua tau raws li cov qauv kev nyab xeeb xwb. Nrog rau kev tso pa tawm tsawg thiab tsis muaj cov pa phem tsim tawm thaum lub sijhawm hlawv, TF-211 thiab TF-212 tab tom teeb tsa cov qauv tshiab hauv kev nyab xeeb hluav taws rau cov kab ke thauj mus los ntawm tsheb ciav hlau.
Xaiv TF-211 thiab TF-212 rau kev nyab xeeb thiab kev ntseeg siab tsis muaj qhov sib piv hauv cov ntaub tiv thaiv hluav taws, ua kom muaj kev taug kev nyab xeeb dua rau txhua tus neeg caij tsheb.
