Kev Ntsuam Xyuas Ntawm Hluav Taws Xob-Resistant Mica Daim Kab Xev Rau Hlau Thiab Cable

Nyob rau hauv refractory mica daim kab xev, daim ntawv mica yog cov khoom siv hluav taws xob tiag tiag thiab cov khoom siv refractory, tab sis daim ntawv mica nws tus kheej yuav luag tsis muaj zog thiab yuav tsum tau ntxiv nrog cov khoom siv txhawb zog los txhim kho nws, thiab ua kom cov ntawv mica thiab cov ntaub ntawv txhawb zog ua ib qho yuav tsum tau ua. siv cov nplaum. Cov khoom siv raw rau refractory mica daim kab xev yog li ua los ntawm mica ntawv, cov khoom siv ntxiv (iav ntaub los yog zaj duab xis) thiab cov nplaum nplaum.

1.1 Mica ntawv
Mica daim ntawv tau muab faib ua peb hom raws li cov khoom ntawm mica cov zaub mov siv.
(1) Mica ntawv ua los ntawm mica dawb;
(2) Mica ntawv ua los ntawm kub mica;
(3) Mica ntawv ua los ntawm hluavtaws mica li raw khoom.
Peb hom ntawv mica no txhua tus muaj lawv cov yam ntxwv

Nyob rau hauv peb hom mica ntawv, chav tsev kub hluav taws xob cov khoom ntawm cov ntawv dawb mica yog qhov zoo tshaj plaws, hluavtaws mica ntawv yog qhov thib ob, kub mica ntawv tsis zoo. Cov khoom hluav taws xob ntawm qhov kub thiab txias, cov ntawv hluavtaws mica yog qhov zoo tshaj plaws, cov ntawv kub mica yog qhov zoo tshaj plaws thib ob, cov ntawv dawb mica yog cov neeg pluag. Synthetic mica tsis muaj crystalline dej thiab muaj qhov melting point ntawm 1,370 ° C, yog li nws muaj qhov zoo tshaj plaws tiv thaiv rau kub kub; kub mica pib tso dej crystalline ntawm 800 ° C thiab muaj qhov thib ob zoo tshaj plaws tiv taus kub; dawb mica tso tawm cov dej crystalline ntawm 600 ° C thiab muaj qhov tsis zoo rau qhov kub thiab txias. Kub mica thiab hluavtaws mica feem ntau yog siv los tsim refractory mica tapes nrog zoo refractory zog.

1. 2 Cov khoom siv ntxiv
Cov ntaub ntawv txhawb nqa feem ntau yog iav ntaub thiab yas zaj duab xis. Cov ntaub iav yog ib qho txuas ntxiv ntawm cov iav fiber ntau ua los ntawm iav tsis muaj alkali, uas yuav tsum tau woven. Cov yeeb yaj kiab tuaj yeem siv ntau hom yas zaj duab xis, kev siv cov yeeb yaj kiab yas tuaj yeem txo cov nqi thiab txhim kho kev puas tsuaj ntawm qhov chaw, tab sis cov khoom tsim tawm thaum lub sij hawm combustion yuav tsum tsis txhob rhuav tshem cov rwb thaiv tsev ntawm daim ntawv mica, thiab yuav tsum muaj lub zog txaus, tam sim no Feem ntau siv yog polyester zaj duab xis, polyethylene zaj duab xis, thiab lwm yam Nws yog tsim nyog hais tias lub tensile lub zog ntawm mica daim kab xev yog muaj feem xyuam rau cov hom ntawm reinforcing cov ntaub ntawv, thiab tensile kev ua tau zoo ntawm mica daim kab xev nrog iav ntaub reinforcement yog feem ntau siab dua li ntawm mica daim kab xev. nrog rau zaj duab xis reinforcement. Tsis tas li ntawd, txawm hais tias IDF lub zog ntawm mica tapes nyob rau hauv chav tsev kub muaj feem xyuam rau hom mica ntawv, nws kuj tseem muaj feem xyuam nrog cov khoom siv ntxiv, thiab feem ntau IDF lub zog ntawm mica tapes nrog cov yeeb yaj kiab reinforcement ntawm chav tsev kub siab tshaj qhov ntawd. ntawm mica tapes tsis muaj zaj duab xis reinforcement.

1. 3 Resin adhesives
Cov nplaum nplaum ua ke muab cov ntawv mica thiab cov khoom siv ntxiv rau hauv ib qho. Cov nplaum nplaum yuav tsum raug xaiv kom ua tau raws li cov ntawv cog lus siab ntawm cov ntawv mica thiab cov khoom siv ntxiv, cov ntaub nplaum mica muaj qee qhov yooj thiab tsis char tom qab hlawv. Nws yog ib qho tseem ceeb uas daim kab xev mica tsis char tom qab hlawv, vim nws ncaj qha cuam tshuam rau cov rwb thaiv tsev ntawm mica daim kab xev tom qab hlawv. Raws li cov nplaum, thaum sib txuas cov ntawv mica thiab cov khoom siv ntxiv, nkag mus rau hauv lub qhov hws thiab micropores ntawm ob qho tib si, nws dhau los ua cov khoom siv hluav taws xob yog tias nws hlawv thiab char. Tam sim no, feem ntau siv cov nplaum rau refractory mica daim kab xev yog silicone resin nplaum, uas ua rau dawb silica hmoov tom qab combustion thiab muaj hluav taws xob rwb thaiv tsev zoo.
