Kev siv Mica hauv cov khoom siv hluav taws xob rwb thaiv tsev
Mica yog dav siv nyob rau hauv hluav taws xob rwb thaiv tsev vim nws zoo heev thermal thiab hluav taws xob insulating zog. Nov yog nws cov ntawv thov tshwj xeeb hauv daim teb no:
Insulating khoom
Mica qhov zoo tshaj plaws thermal thiab hluav taws xob rwb thaiv tsev ua rau nws zoo tagnrho rau siv hauv cov khoom siv hluav taws xob. Hauv cov khoom siv xws li motors thiab transformers, mica feem ntau ua tiav rau hauv cov ntawv nyias lossis cov kab xev rau insulate hluav taws xob windings. Qhov no ua kom ruaj khov ua haujlwm nyob rau hauv high-temperature thiab high-voltage tej yam kev mob.
Cov khoom siv sib xyaw
Mica tuaj yeem ua ke nrog cov organic resins xws li epoxy lossis phenolic los tsim mica boards siv rau hauv cov khoom siv hluav taws xob. Epoxy mica boards nthuav tawm cov khoom siv hluav taws xob zoo tshaj plaws thiab tau siv dav hauv cov khoom siv cua sov ua cov ntaub qhwv thiab cov kev txhawb nqa insulating. Los ntawm kev kho cov khoom sib piv thiab cov txheej txheem tsim khoom, epoxy mica cov khoom tuaj yeem raug kho kom tau raws li cov kev cai tshwj xeeb ntawm cov khoom siv hluav taws xob sib txawv.
Kev siv Capacitor
Mica feem ntau siv hauv kev tsim cov capacitors. Piv txwv li, mica ua cov khoom siv dielectric hauv ceramic capacitors. Nws cov khoom dielectric zoo heev ua rau nws xaiv qhov kev xaiv ntau zaus xws li xov tooj cua sib txuas lus thiab cov khoom siv hluav taws xob.
Kev Tiv Thaiv Thermal Runaway
Mica cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv thermal runaway nyob rau hauv lub hwj chim roj teeb ntawm lub zog tshiab tsheb. Lawv qhov kub thiab txias tsis kam thiab cov khoom rwb thaiv tsev ua rau lawv qhov tseem ceeb rau kev nyab xeeb ntawm roj teeb. Mica boards tuav cov rwb thaiv tsev zoo txawm tias nyob hauv ib puag ncig xws li 500 degree txog 1000 degree, uas yog qhov tseem ceeb hauv kev tiv thaiv hluav taws kub thiab tawg los ntawm thermal khiav.
Cov txheej txheem los tuav cov pa taws los ntawm Cov Ntawv Kub Kub Mica
Mica sheets yog cov khoom siv hluav taws xob uas siv hluav taws xob feem ntau siv hauv cov khoom siv hluav taws xob high-voltage. Thaum ib daim ntawv mica emissions pa luam yeeb vim overheating, nws yog feem ntau tshwm sim los ntawm overload, luv luv Circuit Court, los yog lwm yam malfunctions. Hauv qab no yog qee txoj hauv kev los daws cov xwm txheej zoo li no
Disconnect lub fais fab mov
Tam sim ntawd disconnect lub hwj chim qhov chaw yog tias muaj pa luam yeeb. Qhov no tiv thaiv kev puas tsuaj ntxiv thiab tshem tawm cov xwm txheej muaj kev nyab xeeb.
Siv lub tshuab tua hluav taws tsim nyog
Yog tias cov pa taws ua rau hluav taws me me, siv lub tshuab tua hluav taws uas tsim nyog los tua nws. Xyuas kom koj xaiv lub tshuab tua hluav taws xob tsim nyog rau hluav taws xob hluav taws xob. Tsis txhob siv cov dej tua hluav taws hauv cov khoom siv hluav taws xob nyob.
Ventilate cheeb tsam
Rau qhov hluav taws kub loj lossis cov pa luam yeeb hnyav, ua qhov tseem ceeb ntawm qhov cua kom tshem cov pa taws thiab txo qhov kev pheej hmoo ntawm kev nqus pa phem. Siv cov kiv cua lossis qhib qhov rais los txhim kho huab cua.
Siv lub tshuab tua hluav taws carbon dioxide
Yog tias cov pa taws tshwm sim los ntawm cov khoom siv hluav taws xob tsis ua haujlwm, siv CO₂ extinguisher. Cov pa roj carbon dioxide tsis yog cov khoom siv hluav taws xob thiab tawm tsis muaj qhov seem, kom ntseeg tau tias cov khoom siv hluav taws xob tseem tsis muaj kev puas tsuaj.
Tshawb xyuas thiab kho lossis hloov cov khoom siv
Yog tias cov pa luam yeeb los ntawm cov khoom siv tsis ua haujlwm, tshuaj xyuas cov khoom cuam tshuam kom zoo. Kho lossis hloov cov khoom puas los tiv thaiv kev tshwm sim yav tom ntej.
Kev nyab xeeb ua ntej
Thaum tuav cov pa luam yeeb lossis hluav taws uas muaj cov nplooj ntawv mica:
Ua ntej kev nyab xeeb ntawm tus kheej thiab khiav tawm yog tias qhov xwm txheej ua rau muaj kev phom sij.
Tshem tawm txhua qhov chaw siv hluav taws xob ua ntej sim muaj kev cuam tshuam.
Xaiv txoj kev tua hluav taws thiab qhov cua raws li qhov hnyav ntawm qhov hluav taws kub thiab cov khoom siv.
1. Kev faib tawm ntawm Mica cov khoom
(1) Cov khoom siv Mica tiav
Cov txheej txheem mica yog tsim los ntawm kev kho thiab kho cov mica nyoos rau hauv cov ntaub ntawv xws li nplooj ntawv, hmoov, lossis cov khoom sib xyaw. Nws tuaj yeem categorized rau hauv:
Fine Powders: Siv rau hauv daim ntawv thov xws li mica slurry, wallpaper coatings, cov ntaub ntawv refractory, plastics, pressed sheets, thiab barium chlorate ceramics.
Cov ntaub ntawv: Feem ntau siv rau rwb thaiv tsev, kub tsis kam, hluav taws xob rwb thaiv tsev, thiab thermal conductivity.
Mixed Raw Materials: Xws li cov khoom xws li graphitized mica bricks, mica rau tes, Teflon-mica mixs, thiab mica slurry.
(2) Ntuj Mica Khoom
Cov no muaj xws li ntau yam tshwm sim, xws li daim hlau nyob rau hauv ntxoov grey-ntsuab, sib sib zog nqus xim av, ntshav, los yog reddish-ntsuab. Ob yam tseem ceeb yog:
Short Fiber Mica Khoom:
Uas feem ntau ntawm cov fibers, cov khoom no yog ua tiav los ntawm spinning, weaving, kho cua sov, thiab deposition. Lawv yog siv los txhim kho lub zog, shrinkage kuj, thiab tawg tsis kam ntawm ceramics, gypsum, cement, thiab cov khoom siv hluavtaws.
Powdered Mica Khoom:
Ua los ntawm mica hmoov los ntawm sieving, kev faib tawm, thiab kev sib xyaw ua ke. Cov khoom no feem ntau yog siv rau hauv cov khoom siv, hluav taws xob rwb thaiv tsev, thiab cables.
Mica's versatility thiab cov khoom tshwj xeeb tso cai rau kev hloov kho dav dav thoob plaws nws cov ntawv ntau yam, ua rau nws yog ib qho khoom tseem ceeb hauv ntau daim ntawv thov kev lag luam.
