Nyob rau hauv xyoo tas los no, hom tshiab ntawm cov ntaub ntawv refractory - ceramic refractory silicone roj hmab thiab ceramic refractory silicone roj hmab composite siv nyob rau hauv zus tau tej cov refractory cables, uas yeej yuav daws tau qhov teeb meem ntawm lub saum toj no ob hom ntawmrefractory cables.
1. Cov yam ntxwv ntawm ceramic refractory silicone roj hmab
Ceramic refractory silicone roj hmab yog tsim los ntawm kev ntxiv cov khoom siv ua haujlwm rau kub kub vulcanization (HTV) silicone roj hmab.Kub thiab kub tsis kam, ozone aging kuj, huab cua aging kuj, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo thiab kev ua haujlwm zoo;Nyob rau hauv qhov kub thiab txias nplaim ablation, cov silicone roj hmab sib tov sib xyaw ntxiv nrog cov ntaub ntawv ua haujlwm ua cov txheej txheem nyuaj ceramic armor tiv thaiv txheej, Nws tuaj yeem ua lub luag haujlwm ntawm cov nplaim hluav taws, tiv thaiv hluav taws, rwb thaiv tsev, rwb thaiv tsev kub, dej rwb thaiv tsev thiab av qeeg, yog li ua kom tus du. ntws ntawm hluav taws xob thiab kev sib txuas lus thaum muaj hluav taws kub.
2. Lub tshuab hluav taws xob tiv thaiv thiab hluav taws kub tsis kam ntawm ceramic refractory silicone roj hmab
Cov ntaub ntawv zoo tib yam polymer yog hloov mus rau hauv cov hmoov tshauv tom qab nplaim hluav taws, thiab tsis tuaj yeem hloov mus rau hauv cov khoom siv ceramic;ceramic fireproof thiab refractory silicone roj hmab tuaj yeem sintered ntawm qhov kub tsis kub tshaj 500°C thiab nplaim taws ablation saum 620°C. Lub sij hawm ablation ntev dua thiab qhov kub siab dua, qhov pom tseeb dua cov nyhuv ceramization yog, thiab qhov kub ntawm ablation tuaj yeem ncav cuag 3000.℃;ceramicized hluav taws-resistant thiab refractory silicone roj hmab tuaj yeem tsim siv cov khoom siv roj hmab ua haujlwm.Cov khoom tiav muaj tag nrho cov khoom ntawm silicone roj hmab thiab muaj kev ua haujlwm zoo.
Nws yog cov khoom sib xyaw uas tuaj yeem ua cov plooj (porcelainized) ntawm qhov kub thiab txias los ntawm kev ntxiv cov roj hmab silicone.Nws tuav tag nrho cov yam ntxwv ntawm silicone roj hmab ntawm chav tsev kub.Thaum ntsib flameless kub siab tshaj 500℃thiab nplaim ablation saum 620℃, nws yuav hloov mus rau hauv inorganic ceramics.Cov khoom siv ceramic no muaj qhov zoo ntawm cov rwb thaiv tsev ceramic, rwb thaiv tsev kub, hluav taws kub rwb thaiv tsev, dej rwb thaiv tsev, poob siab tsis kam, thiab thermal poob me me.
Ceramic hluav taws-resistant thiab refractory silicone roj hmab yog non-toxic thiab tsw nyob rau hauv chav tsev kub, muaj zoo softness thiab elasticity, thiab zoo heev noo noo kuj thiab dej nqus kuj.Nws muaj cov yam ntxwv ntawm silicone roj hmab.Ceramic refractory silicone roj hmab tuaj yeem hlawv los ntawm cov nplaim taws Tom qab hlawv rau 2-4 feeb, nws pib sinter rau hauv lub plhaub tawv tawv zoo li lub plhaub.Cov txheej txheej insulating ntawm no nyuaj ceramic-zoo li armored plhaub tuaj yeem tiv thaiv cov nplaim taws kom tsis txhob hlawv;thiab nws yog kiag li tawg tom qab hlawv li 2 feeb.Haus luam yeeb, nyob rau hauv cov txheej txheem ablation tom ntej, tsis muaj pa luam yeeb nws tus kheej yuav raug generated;cov pa luam yeeb tsim tawm hauv thawj 2 feeb kuj tseem tsis muaj halogen, tsis muaj tshuaj lom, thiab tsis muaj mob;Cov pa luam yeeb feem ntau yog cov pa luam yeeb tsim tawm tom qab kev sib xyaw ntawm cov organic silicon, cov khoom siv zoo li cov khoom siv hluav taws xob yog cov tawv tawv thiab tsis sib xws honeycomb plhaub.Cov khoom zoo li no muaj kev rwb thaiv tsev zoo heev, rwb thaiv tsev kub, hluav taws kub thiab hluav taws, thiab tuaj yeem tiv taus kev poob siab thiab kev co, thiab tiv thaiv dej infiltration.Nws ua kom cov dej ntws zoo ntawm txoj kab hauv rooj plaub ntawm kev txau thiab kev co.
Ceramic refractory silicone roj hmab composite siv
Ceramic refractory silicone roj hmab composite daim kab xev yog tsim los ntawm kev txuas ceramic hluav taws-resistant thiab refractory silicone roj hmab rau lub siab kub-resistant iav fiber ntau daim ntaub raws li ib tug tej thickness los ntawm cov txheej txheem sib txuas, tom qab txiav, thiab qhwv nws nyob rau hauv qhov hluav taws kub-resistant. thiab refractory hlau thiab cable.
