Zero Expansion Silica Cib

Zero expansion silica cib yog ib yam tshiab ntawm cov khoom zoo refractory cib, hloov khoom ntawm silica cib, nrog zoo heev thermal shock resistance! Nws tau ua dej txias ntawm 1100 degrees rau ntau tshaj 50 zaug yam tsis muaj qhov tawg. Kev khiav hauj lwm kub: qis dua 1200 degrees, nyob rau hauv kev ua hauj lwm tej yam kev mob yuav tsum tau thermal shock resistance! Cov khoom no yog tsim rau siv nyob rau hauv acidic cua.

1. Zero expansion silica cib SiO2 cov ntsiab lus yog ntau dua 99%, nrog rau corrosion kuj zoo heev thiab acid kuj;
2. Cov ntsiab lus Fe2O3 tsawg tsawg dua 0.1%, tsis muaj kuab paug rau cov khoom (xws li iav kua, thiab lwm yam);
3. Tsawg flux Performance index (Al2O3+2R2O) tsawg dua 0.3%;
4. Lub thermal expansion tus nqi yog ze rau xoom, yog li tsis tas yuav tsum tau khaws cov pob qij txha expansion thaum kho, uas ua rau kom nruj ntawm cov masonry;
5. Cov thermal stability zoo heev, cov khoom yuav tsis tawg thaum lub sij hawm kho kub, thiab tuaj yeem kho ncaj qha ntawm qhov kub thiab txias yam tsis muaj qhov cub tawg;
6. Tom qab kho (kub kho), tev thiab lwm yam tshwm sim yuav tsis tshwm sim, thiab nws muaj kev nyab xeeb thiab txhim khu kev qha rau kev siv mus ntev;
7. Zoo corrosion kuj. Vim tsis muaj calcium, corrosion tsis tuaj yeem tsim

Zero expansion silica bricks yog siv nyob rau hauv: Oxygen combustion furnace, tsis muaj xim / xim lub raj mis iav kiln, superstructure, ntab kiln, kub kub, siab load thiab siab alkali iav tank kiln;

Vim li cas xoom expansion silica bricks nthuav?

1. Kev hloov pauv ntawm lub cev thiab tshuaj lom neeg ntawm xoom-expansion silica cib thaum lub sijhawm tua.

Thaum lub sij hawm firing txheej txheem, muaj cov nram qab no kev hloov nyob rau hauv qhov kub thiab txias: cov dej seem yog tawm ntawm lub cib hauv qab 150 degree, Ca(OH)2 pib decompose ntawm 450 degree; Thaum Ca(OH)2 lub cev qhuav dej ua tiav ntawm 40 ~ 500 degree, cov silica hais Cov ntawv cog lus nrog cov txiv qaub raug rhuav tshem thiab lub zog ntawm lub cev ntsuab tau txo qis heev. Nyob rau hauv qhov kub ntawm 550650, -synthetic hloov mus rau -synthetic. Vim tias 0.82% ntim nthuav dav thaum lub sijhawm hloov pauv, microcracks nrog qhov sib txawv yuav tshwm sim hauv cov siv lead ua. Ntawm 600700, CaO thiab SiO2 tau txais cov tshuaj tiv thaiv theem, thiab lub zog ntawm lub cib nce. Pib los ntawm 1100, qhov kev hloov pauv ceev ntawm Yingshi tau nce siab heev, thiab qhov feem ntawm cov cib ntsuab poob qis heev. Nyob rau lub sijhawm no, qhov ntim ntawm cov cib ntsuab tau nce zoo heev vim yog lub sijhawm hloov pauv mus rau qhov sib txawv ntawm qhov tsawg. Lub sijhawm no, txawm hais tias cov kua theem tsis tu ncua, cov kab nrib pleb tseem tshwm sim nyob rau hauv thaj tsam ntawm 1100 ~ 1200.

2. Lub ntim ntawm xoom expansion silica cib hloov thaum lub sij hawm cua sov txheej txheem, thiab lub ntim yog txawv nyob rau hauv txawv kub theem.

Raws li kev hloov pauv ntawm ntau lub cev siliceous, lawv tuaj yeem muab faib ua theem qis dua 600, 600 ~ 1100, 1100 ~ 1250 thiab siab dua 1250. Muaj qhov tseem ceeb txuas ntxiv mus rau 500600 tus qauv hloov raws sijhawm. Ntawm 700800, CaO thiab SiO2 tau txais cov tshuaj tiv thaiv theem, ua rau micro-shrinkage. Ntawm 1000 ~ 1100, lub shrinkage yog pom tseeb vim yog tsim cov kua theem. Pib los ntawm kwv yees li 1200, vim qhov nrawm ntawm lub sijhawm hloov pauv, lub cev ntsuab pib nthuav dav, thiab qhov pib kub thiab nce kev sib txawv heev nyob ntawm seb hom khoom siv raw.
