Cov lus piav qhia ntxaws ntxaws ntawm cov txheej txheem ntau lawm ntawm ceramic fiber pam:
Pob zeb av nplaum thiab kaolin yog crushed los ntawm ib tug pulverizer rau hauv qhov yuav tsum tau loj rau manufacturing ceramic fibers; los yog sib xyaw nrog cov feem pua ntawm kev lag luam txhuas hmoov, muaj silica hmoov, thiab zircon xuab zeb hmoov los ua plaub yam khoom sib txawv.
Thaum ua cov khoom sib txawv, cov khoom siv raw uas tau npaj saum toj no yog sib npaug ntawm cov khoom noj khoom haus thiab cov khoom sib tov, thiab tom qab ntawd thauj thiab faib rau lub qhov cub ua haujlwm.
Lub tshuab hluav taws xob kuj siv molybdenum electrodes ua qhov chaw ntawm thermal zog. Conductive ions tsim los ntawm molten raw khoom ua lub zog.
Cov hluav taws xob tsis kam tsim los ntawm cov khoom siv molten yog qhov ua kom muaj cua sov, thiab cov khoom siv txuas ntxiv mus rau melted uniformly.
Lub qhov cub tiv thaiv yog txias los ntawm dej. Cov kua molten ntws tawm los ntawm molybdenum orifice ntsia nrog nitrogen tiv thaiv thiab ntws mus rau lub spinning roller ntawm lub tshuab spinning. Los ntawm lub zog centrifugal, cov khoom siv magma molten hloov mus rau hauv fibers, thiab cov roj yog siv rau hauv cov txheej txheem fiber ntau.
Cov fibers tau tshuab tawm los ntawm lub tshuab spinning, coj los ntawm qhov tsis zoo siab, thiab sib npaug sib npaug ntawm txoj siv mesh ntawm cov paj rwb. Cov fibers nkag mus rau hauv rab koob punch los ntawm txoj siv conveyor, thiab rab koob punch hloov cov paj rwb fiber ntau rau hauv cov ntaub qhwv fiber ntau raws li xav tau. .
Koob-punched daim pam paj rwb embryo dhau los ntawm txoj siv conveyor, los ntawm kev kho cua sov rauv kom volatilize cov roj, ua kom nws zoo, crystallize fiber ntau, thiab ua kom nws siv kub. Tom qab ntsug thiab kab rov tav txiav, dov, kev tshuaj xyuas zoo thiab ntim khoom, cov khoom tiav raug xa mus rau lub tsev rau khoom xa tuaj.
Cov txheej txheem yog tsis muaj kuab paug. Cov khoom siv raw khoom yog cov khoom siv coke gemstones los yog sib xyaw ntawm quartz xuab zeb, alumina hmoov thiab zircon xuab zeb. Siv lub hauv paus ntsiab lus ntawm hluav taws xob tiv thaiv hluav taws xob los tsim tam sim no thiab smelt rau hauv cov kua, tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv lossis cov pa phem hauv cov txheej txheem tsim khoom. Ib feem ntawm cov plua plav thiab cov pov tseg uas tsim tawm thaum lub sijhawm yuav rov qab los thiab tshem tawm los ntawm cov dej zeb plua plav collector. Cov txheej txheem no tau tsim thoob plaws. Cov txiv kab ntxwv ua haujlwm sab hauv tsev thiab feem ntau ntawm lawv yog tswj semi-automatically. Cov neeg ua haujlwm tsuas yog yuav tsum hnav cov kev tiv thaiv yooj yim, xws li hnab looj tes, qhov ncauj qhov ntswg, thiab tsom iav. Nws tuaj yeem ua haujlwm ib txwm thiab tuaj yeem xa mus rau tib neeg lub cev yam tsis muaj kev phiv.
Ceramic fiber daim pam txais cov txheej txheem nruam melting thiab nruam spinning yam tsis muaj hauv ob sab phlu dej tsis kam rauv rau hauv fiber ntau, thiab ob-sided koob punching molding; cov fiber ntau ntev, tuab thiab tsis sib xws hauv txoj kab uas hla, siab tensile lub zog, muaj zog tsis kam rau airflow yaig, thiab zoo thermal stability. Los ntawm kev kho cua sov ntawm tag nrho-automated daim pam cua sov rauv, cov khoom siv fiber ntau tuaj yeem hloov ua ntej, thiab qhov kub thiab txias shrinkage ntawm cov khoom thaum siv yuav raug txo. Nyob rau tib lub sijhawm, kev siv cov khoom siv zoo raw khoom thiab kev ua kom huv huv tshwj xeeb thiab kev sib xyaw ua haujlwm tuaj yeem txo cov khoom lag luam zoo. Cov ntsiab lus impurity nyob rau hauv cov khoom txhim kho cov thermal stability ntawm cov khoom.
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm ntawm ceramic fiber pam yog sau tseg raws li hauv qab no:
Qhov ntim me me; muaj peev xwm tsis tshua muaj cua sov (kub cia); tsawg thermal conductivity; zoo heev thermal shock thiab mechanical vibration kuj; zoo suab rwb thaiv tsev kev ua tau zoo; yooj yim tsim thiab tu
Qhov zoo tuaj yeem muab faib ua tsib pawg:
(1) Kev ua haujlwm zoo ib puag ncig. Nws yog tsim los ntawm spun silk fiber nrog ib txoj kab uas hla ntawm 5 microns, fiber ntau ntev ntawm 200 hli, thiab siab tensile zog. Nws tsis yooj yim los tsim cov plua plav thaum siv thiab tu, thiab cov plua plav generated tsis ua rau muaj kev phom sij rau kev ua haujlwm thiab tsis cuam tshuam rau tib neeg kev noj qab haus huv.
(2) Lub zog tensile zoo heev. Cov khoom siv ob npaug rau rab koob xuas nrig ntaus thiab muaj lub zog tensile ntawm 40, 000 Pa ntawm qhov ceev ntawm 128kg / m3.
(3) Kev ua haujlwm zoo thermal rwb thaiv tsev. Qhov ntsuas kub ntawm cov khoom no yog 1260 degree, qhov kev nyab xeeb siv kub yog qis dua 1000 degree, thermal conductivity me me, thiab thermal conductivity tsuas yog 0.085 nyob rau hauv nruab nrab 400 degree, uas zoo txhim kho cov khoom thermal rwb thaiv tsev. kev ua tau zoo.
(4) Kev ruaj ntseg tshuaj zoo heev, thermal stability, thermal shock kuj thiab suab haum, yooj yim siv thiab tu.
