Lub fireproof mechanism ntawm steel qauv fireproof txheej

Steel qauv fireproof coatings ncua qhov kub nce ntawm steel nyob rau hauv hluav taws kub los ntawm ntau yam mechanisms, kom ntseeg tau cov yam ntxwv stability nyob rau hauv siab kub.

Lub ntsiab fireproof mechanisms yog raws li nram no:

Thermal Barrier Tsim

• Intumescent txheej: Thaum raug kub kub, txheej txheej nthuav tawm los ua ib txheej txheej ntxeem tau, insulating tiv thaiv tshav kub thiab oxygen, yog li ua kom cov hlau kub nce.
• Non-inumescent Coatings: Siv cov khoom ua kom muaj cua sov siab thiab tsis tshua muaj thermal conductivity (piv txwv li, aluminium hydroxide, magnesium hydroxide) kom nqus tau cov cua sov thiab tsim ib txheej insulating.
• Endothermic Reactions

• Thaum tshav kub kub Absorption ntawm Decomposition: Fillers xws li aluminium hydroxide thiab magnesium hydroxide decompose nyob rau hauv qhov kub thiab txias, nqus cua sov thiab txo cov hlau kub.
• Theem Hloov Thaum Kub Absorption: Qee lub tshuab nqus tsev nqus cua sov los ntawm theem hloov ntawm qhov kub thiab txias, ncua lub steel kub nce.2Inert Gas tso tawm

• Gas Emission: Thaum kub kub, txheej txheej decomposes thiab tso tawm inert gases (xws li, nitrogen, carbon dioxide), diluting oxygen concentration thiab suppressing combustion.Char Txheej Kev Tiv Thaiv

• Char Formation: Intumescent coatings tsim ib txheej tuab tuab ntawm qhov kub thiab txias, tiv thaiv cov hlau los ntawm tshav kub thiab oxygen.
• Char Txheej Stability: Lub char txheej tseem ruaj khov nyob rau hauv qhov kub thiab txias, muab kev tiv thaiv tas mus li.
• Tshuaj Reactions

• Nplaim Retardant Effects: Cov nplaim hluav taws (piv txwv li, phosphorus-based, nitrogen-based) hauv cov txheej txheem tsim hluav taws-inhibiting tshuaj ntawm qhov kub thiab txias, suppressing combustion tshua.
• Lub cev Barrier

• Txheej Thickness: Ntau txheej txheej thickness txhim khu kev rwb thaiv tsev, ncua lub steel kub nce.
• Cov qauv ntom ntom: Cov txheej txheej tsim cov qauv compact, zoo thaiv cov cua sov thiab oxygen.
• Steel qauv fireproof coatings siv ntau yam mechanisms-thermal barrier tsim, endothermic cov tshuaj tiv thaiv, inert gas tso, char txheej tiv thaiv, tshuaj tiv thaiv, thiab lub cev barriers-kom ncua lub steel kub nce thaum lub sij hawm hluav taws kub, ua kom cov txheej txheem stability nyob rau hauv high kub. Cov txheej txheem no ua haujlwm ua ke los muab kev tiv thaiv hluav taws zoo.
• Ammonium Polyphosphate is a key product for intumescent coatings , usually working together with melamine and pentaerythritol . TF-201 is a popular grade for water based intumescent coating with good water stability in storage. More info., pls contact lucy@taifeng-fr.com
