Intumescent hluav taws-resistant txheej
TXOJ KEV UA HAUJ LWM NTAWM COV TXHEEJ TXHEEM HLUAV TAWS KUB HEEV TSHAJ PLAWS YOG NYOB RAU HAUV COV NTAUB NTAWV NO:
Nthuav dav thaum ntsib hluav taws, tsim ib txheej rwb thaiv cua sov zoo: Qhov no yog nws qhov kev ua tau zoo tseem ceeb. Thaum lub txheej raug hluav taws, cov tshuaj tiv thaiv hluav taws sab hauv thiab cov khoom ua npuas ncauj teb sai sai, ua rau lub ntim nthuav dav 5 zaug txog 20 zaug lossis ntau dua; piv txwv li, ib yam khoom tuaj yeem nthuav dav 20 zaug thaum 0.6 hli tuab thaum ntsib hluav taws, tsim ib txheej carbonized lossis txheej ceramic. Cov txheej nthuav dav no tuaj yeem cais cov cua sov thiab oxygen tau zoo, ua rau qeeb qhov kub ntawm lub substrate nce. Kev tiv thaiv kub siab thiab cov khoom rwb thaiv cua sov zoo heev: Cov txheej txheej zoo tuaj yeem tiv taus qhov kub ntawm nplaim taws siab heev. Piv txwv li, ib yam khoom tuaj yeem ua kom qhov kub rov qab tsis siab tshaj 200 ℃ hauv 5 feeb thaum raug nplaim taws 1000 ℃; lwm txoj kev tshawb fawb qhia tau tias ntawm nplaim taws 850 ℃ rau 15 feeb, qhov kub ntawm qhov chaw txias tsuas yog 122.3 ℃. Qee cov txheej txheej tshwj xeeb tuaj yeem muaj qhov txwv tsis pub kub txog li 2000 ℃. Cov qauv porous lossis lub tshuab nqus tsev uas tsim tom qab nthuav dav muaj qhov ua tau thermal conductivity qis heev (xws li txog li 0.022W / mK), ua rau muaj cov teebmeem rwb thaiv tsev kub zoo kawg nkaus.
Los ntawm kev ncua qhov kev hloov pauv cua sov los ntawm cov txheej rwb thaiv tsev, nws tuaj yeem tiv thaiv cov khoom siv xws li cov qauv hlau, tswj lawv lub zog txawm tias nyob rau hauv qhov kub siab. Rau kev tsim cov qauv hlau, qhov no tuaj yeem muab 1-3 teev lossis ntev dua rau kev tiv thaiv cov neeg ua haujlwm tawm thiab cawm neeg tua hluav taws.
Cov khoom zoo thiab lub cev zoo: Cov txheej txheem nthuav dav niaj hnub no tsis yog tsuas yog tiv taus hluav taws xwb tab sis kuj muaj kev nplaum zoo heev (qee qhov tuaj yeem ncav cuag qib 0), tiv taus kua qaub thiab alkali corrosion, tiv taus huab cua, thiab tiv taus kev cuam tshuam. Qee cov khoom siv cov tshuaj tsis muaj kuab tshuaj lossis dej, uas yog ib puag ncig zoo thiab tsis muaj tshuaj lom, ua tau raws li cov kev cai tiv thaiv ib puag ncig niaj hnub no.
