Txhawm rau tiv thaiv kev siv cov nyhuv ntawm siab alumina refractory cib los cuam tshuam, kev ua haujlwm tiv thaiv kev ua haujlwm yuav tsum ua kom zoo thaum lub sijhawm tsim khoom, kev thauj mus los thiab kev txawb. Siv tshuab ciab los yog lwm cov tshuaj tua kab mob tshiab tuaj yeem siv rau tshuaj tua tsis taus. Yog hais tias lub siab alumina refractory cib corroded thiab puas ntsoog, nws tus nqi yuav raug txo ntau heev. Feem ntau, qhov ntsuas kub siab lossis tshuab quab yuam yuav ua rau lub pob zeb refractory. Cov hauv qab no yog cov ncauj lus kom ntxaws ntxaws.
, Yuav ua li cas tiv thaiv kom txhob muaj kuab paug ntawm qib siab alumina refractory cib
1, Ciab, organic txheej thiab hydrophobic surfactant antifouling thev naus laus zis: siv quav ciab thiab organic txheej txheem yog cov tshuaj tua kab mob zoo rau saum npoo av siab alumina refractory cib, tab sis cov nyhuv tau tsis txaus siab. Txawm hais tias waxing tuaj yeem tiv thaiv kom txhob muaj kuab paug, qhov nro ntawm npoo ntawm siv quav ciab yog loj. Tsis tas li ntawd, siv quav ciab yog ib hom khoom siv txheej. Airtight sealant.
2, Cov tshuaj fluorine muaj cov nplaim hluav taws xob tsis muaj zog tiv thaiv kev siv thev naus laus zis: cov tshuaj fluorine muaj cov khoom ua rau lub zog qis heev, thiab lub teeb meem saum npoo ntawm perfluoroalkanes yog tsawg li 10 nm. Lub kaum sab xis sib tiv tauj nrog cov organosilicon yog 110: 101, yog li nws muaj cov tshuaj tua kab mob zoo dua thiab tiv thaiv staining muaj peev xwm. Txawm hais tias fluorine-xyaw tebchaw muaj cov khoom zoo antifouling, lawv kim heev. Tsis tas li ntawd, nws tsis yog paub tab heev hauv kev ua haujlwm ntawm fouling technology ntawm siab alumina cib, yog li fluorine compound anti fouling technology tsis tshua muaj siv tam sim no.
3, Organosilicon antifouling thev naus laus zis: lub zog saum npoo ntawm siab aluminium cib saum npoo kev kho mob tus neeg sawv cev yog qhov tseem ceeb tshaj plaws hauv qhov kev ua tiav antifouling. Lub zog qis qis tuaj yeem tiv thaiv cov adsorption ntawm cov plua plav, cov kab mob me me, cov dej-cov dej, cov khoom me, thiab lwm yam. Organosilicon muaj cov nplaim hluav taws xob tsawg, uas tuaj yeem ua tau li 21-22m nm. Nws yog qhov zoo tshaj plaws thiab siv dav siv dej tsis txhuam thiab tshuaj tua kab mob nyob rau saum npoo ntawm siab alumina cib.
二, Dab tsi yog qhov ua kom muaj kev xeb ntawm cov qib alumina refractory cib
1. Nws yog qhov hluav taws xob tsis xwm yeem ntawm cov tawv tawv uas ua rau muaj kev ntxhov siab thermal thiab lub tshuab kev ntxhov siab ntawm lub tshuab ua kom sov, uas ua rau muaj kev puas tsuaj sai ntawm refractory cib txheej.
2. Qhov thib ob yog hu ua cov txheej txheem tawv, uas tshwm sim los ntawm kev nkag ntawm slag thiab qhov kub hloov hloov ntawm qhov chaw ua cua sov. Yog li no, tshwj xeeb txheej txheem qauv txheej txheem tsim, thiab cov kab nrib pleb mus rau cov cua kub tau tsim nyob ntawm qhov chaw nruab nrab ntawm thawj txheej thiab txheej txheem txheej, uas ua rau lub hauv siab ntawm alumina refractory cib tev thiab puas.
3. Qhov thib peb yog hu ua yaj ntws, uas yog tshwm sim los ntawm cov tshuaj tiv thaiv nrog molten steel, hlau tsis xeb thiab slag los tsim cov tshuaj yeeb yaj kiab nrog qis melting point, thiab qhov ua kom yaj yaj ntws lossis hnav yog feem ntau vim yog tsim cov theem ua kua thiab cov dej yaig ntawm txheej txheej saum npoo.
Tsis tas li ntawd, cov kab nrib pleb tshwm sim los ntawm lub ntsws ntawm lub siab alumina cib txheej thiab nthuav tawm lossis qhib ntawm cov pob qij txha vim tshwm sim los ntawm shrinkage ntawm cov khoom refractory nyob rau hauv kev siv ntawm cov kab hauv av ua lub hauv paus tseem yog lub laj thawj rau lub hauv zos kom sai ntawm kev puas tsuaj ntawm hauv ob sab phlu.
