Txhawm rau ua kom yooj yim thiab ua kom nrawm nrawm rau kev tsim kho ntawm qhov cub thiab txhim kho kev ncaj ncees ntawm hauv ob sab phlu, ib hom tshiab ntawm cov khoom muag qis dua. Cov khoom yog dawb thiab tsis tu ncua hauv qhov loj me, thiab tuaj yeem kho ncaj qha rau ntawm steel phaj thauj tog rau nkoj tus pin ntawm lub plhaub muaj cov plaub hau, uas muaj cov hluav taws zoo-tiv thaiv thiab ua kom muaj cua sov ua kom zoo, txhim kho kev ncaj ncees ntawm cov hluav taws kub rwb thaiv tsev, thiab txhawb kev txhim kho ntawm kiln masonry tshuab kev faib tawm kub 1050-1400 temperature
Khoom nta:
Kev ruaj khov tshuaj zoo heev; Zoo heev thermal stability; Tus qauv yog nyob rau hauv kev ua ntej nias lub xeev nrog zoo elasticity. Tom qab hauv ob sab phlu tsim, qhov nthuav ntawm lub module ua rau lub hauv ob sab phlu uas tsis muaj qhov sib txawv, thiab tuaj yeem them nyiaj rau qhov shrinkage ntawm lub laj kab hluav taws xob, thiaj li txhim kho cov rwb thaiv kev ua haujlwm ntawm cov ntawv fiber ntau thiab kev ua haujlwm tag nrho yog qhov zoo; Zoo thermal stability thiab thermal poob siab; Ceramic fiber module tau teeb tsa sai thiab cov thauj tog rau nkoj tau teem rau qhov chaw txias txias ntawm phab ntsa txheej, uas tuaj yeem txo qhov kev xav tau ntawm cov khoom thauj tog rau nkoj.
Daim ntaub ntawv raug:
Lub hauv ob sab phlu rwb thaiv tsev ntawm lub qhov cub hauv kev lag luam petrochemical; Rauv hluav taws xob hauv ob sab phlu rwb thaiv tsev ntawm kev lag luam metallurgical; Rwb thaiv tsev ntawm ob sab phlu ntawm ceramic, iav thiab lwm yam tsev cov ntaub ntawv kev lag luam kilns; Kev kho cua sov kev lag luam ntawm kev kho cua sov cua sov ua kom lub rwb thaiv tsev; Lwm qhov cub muaj roj.
Kev Pab:
Peb tuaj yeem ua tus tsim thermal rwb thaiv tsev thiab kev tsim kho kev kawm raws li cov tshuab hluav taws xob sib txawv ntawm cov neeg siv khoom.
2.Qhov qhov zoo ntawm qhov qauv thov rau cov qhov cub muaj
Nyob rau tam sim no, tag nrho cov qauv ua los ntawm aluminium silicate ceramic fiber pam yog qhov dhau los xaiv thawj cov khoom siv hluav taws xob rwb thaiv tsev rau cov kev lag luam tshiab kiln meem vim nws qhov zoo ntawm qhov kub tsis kam thiab kev tsim kho yooj yim.
Xyoo tsis ntev los no, daim ntawv thov dav ntawm cov khoom no hauv petrochemical, steel, fais fab fais fab, xis mas thiab lwm cov liaj teb tau tsim cov kev tsim kho muaj txiaj ntsig; Qhov kev pab cuam ib-nres ntawm kev txhawb nqa kev tshaj lij, kev pom zoo khoom siv thiab kev soj ntsuam zoo tau yeej qhov kev lees paub tag nrho ntawm txoj cai thiab ntau cov lag luam lub koob npe.
Khoom nta:
1. Thaum lub sijhawm teeb tsa, daim pam folding tom qab khi yuav tsim kev ntxhov siab loj, thiab yuav tsis muaj qhov sib txawv ntawm ob;
2. Lub siab elasticity ntawm daim pam fiber ntau tuaj yeem ua rau deformation ntawm lub plhaub tuv thiab txo nqi kev tsim kho. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau qhov sib txawv ntawm cov sib txawv hauv cov tshuab ua kom sov lub cev vim muaj kev hloov kub sib txawv;
3. Vim hais tias lub teeb hnyav thiab muaj peev xwm kub tsis tshua muaj peev xwm (tsuas yog 1/10 ntawm lub teeb kub-tiv taus lub teeb thiab lub teeb refractory cib), lub zog siv hluav taws xob hauv cov cua sov ua haujlwm tswj tau tuaj yeem txo qis;
4. Elastic fiber pam yuav tiv taus cov neeg kho tshuab sab nraud quab yuam;
5. Muaj peev xwm tiv taus qhov cua kub kub;
6. Lub cev ntaj ntsug tsis tas yuav ziab thiab tu, thiab hauv ob sab phlu tuaj yeem siv tom qab kev tsim kho;
7.Txoj kev hloov tshuaj yog qhov ruaj khov. Tsuas yog phosphoric acid, hydrofluoric acid thiab muaj zog alkali, lwm cov kua qaub, cov hauv paus, dej, roj thiab ncu tsis yaig.
3 、 Cov yam ntxwv ua tau zoo ntawm cov khoom siv fiber ntau refractory
Refractory fiber, tseem hu ua fiber ntau cov fiber ntau, yog qhov zoo tshaj plaws refractory nrog qis tshaj thermal conductivity thiab qhov zoo tshaj plaws thermal rwb thaiv tsev thiab lub zog txuag siv tshwj tsis yog nano cov ntaub ntawv. Nws muaj ntau yam zoo, xws li lub teeb yuag, siab kub tsis kam, zoo rwb thaiv tsev ua haujlwm thiab kev tsim kho yooj yim, thiab yog cov ntaub ntawv zoo rau lub cub tawg kev lag luam. Piv nrog tsoos refractory cib, refractory castable, refractory fiber muaj cov kev ua tau zoo hauv qab no:
a. Lub teeb nyhav (txo cov khoom siv ua kom sov thiab ua kom lub cub tawg ntev dua): cov hluav taws xob refractory fiber yog ib hom fiber ntau zoo li refractory, feem ntau siv cov hluav taws kub fiber ntau pam, nrog lub ntim ntom ntawm 96-128kg / m3, thaum lub ntim ntim ntawm lub refractory fiber module folded los ntawm fiber daim pam yog nruab nrab ntawm 200-240 kg / m3, thiab qhov hnyav yog 1 / 5-1 / 10 ntawm lub teeb refractory cib los yog cov khoom siv amorphous, Nws yog 1 / 15-1 / 20 ntawm hnyav refractory. Nws tuaj yeem pom tau tias txoj kab hluav taws xob refractory fiber ntau tuaj yeem paub lub teeb thiab siab ua kom tiav ntawm lub tshuab ua kom sov, txo cov taws ua kom sov thiab ua kom ntev lub neej ntawm qhov cub tawg.
b. Tsawg tshav kub muaj peev xwm (qhov ua kom tsis muaj cua sov tsawg dua thiab ua kom muaj cua sov ceev): lub peev xwm kub ntawm cov khoom hauv lub lev feem ntau sib piv mus rau qhov hnyav ntawm hauv ob sab phlu. Tsawg tshav kub muaj peev xwm txhais tau hais tias lub cub tawg nqus tau tsawg dua tshav kub hauv kev ua haujlwm thiab qhov ua haujlwm kub ceev dua. Lub peev xwm thermal ntawm ceramic fiber tsuas yog 1/10 ntawm lub teeb kub-tiv taus lub teeb thiab lub teeb refractory cib, uas zoo heev txo lub zog siv hluav taws xob hauv qhov kub tswj, tshwj xeeb tshaj yog rau kev cuam tshuam ua haujlwm ua cua sov, uas muaj lub zog txuag hluav taws xob zoo.
c. Tsawg cov thermal conductivity (tsawg dua thaum tshav kub kub ploj): thaum lub nruab nrab kub yog 200 ℃, cov thermal conductivity tsawg dua 0.06w / mk, thiab qhov kub nruab nrab ntawm 400 ℃ yog tsawg dua 0.10 w / mk, kwv yees li 1/8 ntawm lub teeb cov khoom siv ua kom sov-amorphous, uas yog li 1/10 ntawm lub teeb cib. Piv nrog rau qhov hnyav refractory, lub thermal conductivity ntawm ceramic fiber cov ntaub ntawv tuaj yeem tsis quav ntsej. Yog li cov rwb thaiv tsev cuam tshuam ntawm fiber ntau refractory yog qhov zoo tshaj plaws.
d.Simple kev tsim kho (tsis muaj kev sib koom tes ntxiv yog yuav tsum tau): cov neeg ua haujlwm tsim kho tuaj yeem nqa lawv cov haujlwm tom qab kev qhia theem pib, thiab tus yam ntxwv ntawm kev tsim kho thev naus laus zis los cuam tshuam txog qhov rwb thaiv kev cuam tshuam ntawm lub cub tawg hauv tsev yog me.
e. Cov khoom siv dav siv: nrog kev txhim kho ntawm kev tsim khoom thiab kev siv tshuab ntawm cov hluav taws xob refractory fiber, refractory ceramic fiber khoom tau serialized thiab ua haujlwm. Cov khoom lag luam tuaj yeem ua raws li qhov xav tau ntawm cov qib kub sib txawv ntawm 600 ℃ txog 1400 ℃ los ntawm kev siv kub. Los ntawm cov yam ntxwv ntawm morphology, nws tau maj mam tsim cov txheej txheem theem nrab lossis kev ua cov khoom sib sib zog nqus los ntawm cov paj rwb tsoos, pam, cov khoom lag luam xav mus rau cov qauv fiber ntau, cov phaj, cov seem tshwj xeeb, ntawv, fiber ntau textiles thiab lwm daim ntawv. Nws tuaj yeem ua kom tau raws li qhov xav tau ntawm cov khoom lag luam sib txawv hauv ntau qhov kev lag luam rau kev siv refractory ceramic fiber khoom.
f. Thermal poob siab tsis kam: lub fiber ntau folding module muaj zoo tsis kam mus rau qhov kub hloov pauv. Hauv qab qhov kev xav tau uas cov khoom siv tau lev tuaj yeem dais, lub hauv paus ntawm lub fiber ntau folding module tuaj yeem ua kom sov lossis txias ntawm txhua qhov kev sib tw.
g. Neeg kho tshuab kev co tsis kam (hloov thiab ywj siab): cov pam fiber los yog hnov zoo li hloov tau thiab ywj, thiab nws tsis yooj yim rau kev puas tsuaj. Lub tshuab ua kom sov tag nrho tsis yooj yim rau kev puas tsuaj thaum nws muaj kev cuam tshuam lossis thauj los ntawm kev.
xyob h. Tsis tas yuav tsum tau muaj lub cub ua kom qhuav: tsis muaj txheej txheem ziab khaub ncaws (xws li kev tu, ziab khaub ncaws, ci, txheej txheem ci thiab tiv thaiv kev tiv thaiv hauv huab cua txias) yog qhov yuav tsum tau ua. Lub hauv ob sab phlu tuaj yeem muab tso rau tom qab siv kev tsim kho.
1. Lub suab zoo rwb thaiv kev ua suab nrov (suab nrov muaj kuab paug txo): ceramic fiber tuaj yeem txo lub suab nrov nrov nrog zaus tsawg dua 1000 Hz, thiab rau lub suab yoj suab tsawg dua 300Hz, lub suab rwb thaiv tsev muaj peev xwm zoo dua li ntawm cov khoom siv suab rwb thaiv tsev, thiab tuaj yeem txo cov suab paug qias neeg.
j. Lub zog tsis siv neeg tswj kev muaj peev xwm: cov nplaim hluav taws xob fiber ntau hauv lub siab muaj qhov cua sov zoo, thiab tuaj yeem tsim nyog rau kev tswj tsis siv neeg ua haujlwm ntawm cov cua sov cua sov.
k. Tshuaj lom neeg ruaj khov: cov cuab yeej tshuaj lom neeg cov kua roj carbon fiber ntau hauv lub hauv paus ruaj khov, tshwj tsis yog phosphoric acid, hydrofluoric acid thiab muaj zog alkali, lwm cov kua qaub, cov hauv paus, dej, roj thiab chav yuav tsis yaig.
