Dab tsi yog cov yam ntxwv ntawm cov khoom siv sib txhuam txhuam txhuam, koj puas to taub lawv tiag tiag? (zoo tshaj)
Mineral fiber ntau rau cov khoom sib txhuam txhuam
Cov ntxhia fibers siv nyob rau hauv cov ntaub ntawv sib txhuam feem ntau xa mus rau cov tsis-asbestos composite reinforcing fibers. Cov ntaub ntawv tseem ceeb yog xaiv basalt, diabase, limestone, dolomite, thiab lwm yam, thiab ib qho kev faib ua feem ntawm cov tebchaw ntxiv. Liquefied, tshuab los ntawm cov cua ntws, thiab ua los ntawm fibers ua los ntawm kev kho deg thiab lwm yam txheej txheem. Lub ntsiab zoo ntawm hom fiber ntau yog hnav tsis kam thiab kub tsis kam. Cov khoom sib txhuam muaj cov cua sov zoo thiab muaj cov thermal conductivity coefficient tsawg, uas tuaj yeem txo cov cua sov ntawm lub braking hloov mus rau cov dej nres, tsis txhob overheating ntawm cov dej nres, thiab nres nres. Cov coefficient ntawm kev sib txhuam yog qhov ruaj khov, thiab cov khoom tsim los ntawm cov cuab yeej tsim nyog tuaj yeem txo cov suab nrov ntawm kev sib tsoo.
Antimony sulfide hmoov rau cov khoom sib txhuam txhuam
Antimony sulfide hmoov yog cov hmoov dub, cov khoom tseem ceeb yog antimony (Sb), thiab cov ntsiab lus tseem ceeb yog ntau dua 60 feem pua. Lub melting point ntawm antimony sulfide kuj tsawg. Antimony oxide generated tom qab pyrolysis thiab hlau antimony generated nyob rau hauv lub xub ntiag ntawm txo tus neeg sawv cev tuaj yeem tiv thaiv oxidation thiab combustion ntawm qhov kub thiab txias, ua kom qhov kev ua tau zoo ntawm cov ntaub ntawv sib txhuam ruaj khov, thiab tseem txo cov kev sib txhuam ntawm cov organic binders ntawm qhov kub thiab txias. Decomposition ceev, txhim kho lub neej kev pab cuam ntawm cov khoom. Thaum lub sij hawm braking txheej txheem, lub hardness ntawm high-temperature cov tshuaj tiv thaiv yog tsawg, uas yuav txo tau lub suab nrov thiab vibration generated los ntawm cov khoom sib txhuam thaum lub sij hawm braking.
