Taw qhia: Qhov nce siab xav tau rau Ceramic Fiber ntau lub nroog
Tej hub fiber ntau lub rooj zaumPuas yog kev tsis tseem ceeb hauv kev lag luam uas xav tau huab cua sov huab cua, xws li metallurgy, petrochemicals, thiab aerospace. Cov rooj zaum no, ua los ntawm alumina-silicate fibers, muab lub teeb ci ntsa iab, tsawg thermal conductivity (0.12-0.25 w / menpility txog1,600 ° C (2,912 ° F)Cov. Cov lus qhia no dhia mus rau hauv cov khoom siv raw, cov kauj ruam ntau lawm, thiab kev tswj hwm zoo tsim los tsim cov ceramic fiber ntau lub tsev loj thiab nyab xeeb.
1. Cov Khoom Siv Raw rau Ceramic Fiber Ntauwd
Cov khoom lag luam pib nrog cov khoom xyaw siab:
- Alumina (al₂o₃): 45-55% rau cov qauv txheem; ≥60% rau cov qib siab.
- Silica (sitio): 35-45%, tshuav nyiaj li cas thermal ruaj khov thiab fiber hloov.
Qhov Tseem Ceeb Toom Kev Lag Luam:
- Fiber diam: 2-4 μm (cuam tshuam nrog yooj ywm thiab rwb thaiv tsev).
- Cov ntsiab lus tua:% A≤5% (ntxhib cov lus txo qis).
2. Cov kauj ruam ib theem zuj zus
Kauj ruam 1: Melting thiab fiber ntau
- Melting rauv: Cov ntaub ntawv raw yog melted ntawm1,600-1,800 ° CNyob rau hauv ib lub arc hluav taws xob lossis kev tawm tsam rauv.
- Tiag tiag: Cov khoom siv molten yog spun rau hauv cov fibers siv:
- Tshuab Qauv: Kev siv cov cua ntws ntws tawm los ua cov fibers luv.
- Ntauv Qauv: Centrifugal quab yuam ua tau ntev dua, interlocked fibers.
Kauj ruam 2: Kev Sau Cov Fiber Ntau thiab Tsim
- Chamber Sau: Cov fibers khom rau hauv ib daim pam vov ntawm tus conveyor.
- Lub Tshuab Nqus Tsev: Fibers yog tov nrog binders thiab nqus-tsim rau hauv cov ntawv txheeb.
Kauj ruam 3: nias thiab kom qhuav
- HYDRAULIC XOVXWM: Compress rau daim ntawv los ua hom ntom ntom (260-320 kg / m³).
- Lub Cub Qhuav: Tshem cov dej noo ntawm120-200 ° CKom solorify rau board.
Kauj Ruam 4: Txiav thiab Xov
- Cnc txiav: Precision-txiav cov laug cam rau hauv cov qauv ntau thiab tsawg (piv txwv li, 1,200 × 65 hli) lossis duab kev cai.
- Nto Txheej: Yeem vermiculite lossis txhuas cov ntawv ci rau cov khaubncaws sab nraud povtseg ua kom tsis taus.

4. Kev tswj kom zoo thiab tshuaj ntsuam
- Ceev: Ntsuas los ntawm ASTM C167 (hom phiaj: 260 kg / m³).
- Compressive lub zog: ≥0.5 MPa (ASTM C133).
- Kab shrinkage: ≤3% Tom qab 24h ntawm 1,350 ° C (ISO 2477).
Cov Khoom Tsis Txaus & Cov Ntsiab Lus:
- Tawg pleb: Kho cov ntsiab lus lossis kev ziab nrawm.
- Fiber ntau segregation: Txhim Kho Lub Tshuab Nqus Tsev Siab Siab.
5. Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Txiav Txim Siab
- Kev tiv thaiv neeg ua hauj lwm: Siv N95 lub khob ntsej muag, goggles, thiab hapa cua kom muaj kev nqus tau cov muaj zog fiber ntau.
- Khib Tswjhwm: Rov qab-txiav; pov tseg cov khib nyiab rau ib osha 29 cfr 1910.1001.
- Emissions tswj: Scrubbers lim rauv taws ua pa tawm (son).
6. Cov ntawv thov ntawm Ceramic Fiber ntau lub rooj zaum
- Muaj Kilns: Hauv ob sab phlu rau cov yas ua kom rov ua kom sov.
- Fais fab nroj tsuag: Rwb thaiv tsev rau boilers thiab duct lub tshuab.
- Ib tug tub rog: Thermal teeb meem nyob rau hauv cov pob zeb tawg.
- DIY PROJECTS: Kev Rwb thaiv tsev kev cai rau tsev.
7. Cov Lus Nug Txog Cov Ceramic Fiber Pawg Ntau Lawm
Q: Kuv puas tuaj yeem ua kom cov rooj ceramic fiber ntau hauv tsev?
A: Tsis pom zoo-Industrial-cov khoom siv thiab kev nyab xeeb muaj kev nyab xeeb yog qhov tseem ceeb.
Q: Tus nqi dab tsi los tsim cov ceramic fiber ntau?
A: RAW cov ntaub ntawv account rau 50-60% ntawm cov nqi; Ib tsob nroj me me yuav tsum tau ~ $ 500k kev nqis peev.
Q: Ntev npaum li cas siv lawm?
A: 3-7 hnub los ntawm melting rau cov laug cam tiav.
8. Xaus: Tus khub nrog cov kws tshaj lij rau kev ua tau zoo
Kev tsim khoom ceramic fiber ntau lub duav tau xav tau precision, kev machinery, thiab nruj zoo tswj. Rau kev pib, sib koom tes nrog cov neeg muab khoom pov thawj (piv txwv li,Txiv ntooLossisCais) Kom ua raws li kev ua raws cai thiab ua tau zoo. Rau kev xav tau loj-cov txheej txheem xav tau, siv cov txheej txheem siv rau cnc nrog cnc txiav thiab cov colotic tuav kom txhawb cov zis.
