Nyob rau lub Tsib Hlis, 07TH.2022, KUB SALES, 21 tons Hluav taws kub av nplaum ntxiv rau 30roll Ceramic Fiber Blanket tau ntim rau cov neeg siv khoom hauv Philippines.
Av nplaum cib yog ua los ntawm cov av nplaum clinker li aggregate thiab refractory av nplaum (mos av nplaum los yog semi-mos av nplaum) ua binder ua refractory nrog Al2O cov ntsiab lus ntawm 30 feem pua ~ 48 feem pua. Nws yog cov khoom siv refractory nrog ntau yam kev siv thiab cov khoom siv ntau tshaj plaws.
Cov khoom ntawm cov khoom siv av nplaum hloov pauv ntau yam, uas yog vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem tsim khoom ntawm cov khoom. Cov khoom siv av nplaum feem ntau muaj cov khoom nram qab no:
(1) Tshuaj thiab ntxhia muaj pes tsawg leeg. Cov ntsiab lus ntawm Al₂O₃ yog 30 feem pua ~ 48 feem pua, cov ntsiab lus ntawm SiO2 yog 50 feem pua ~ 65 feem pua thiab ib tug me me ntawm alkali hlau thiab alkaline ntiaj teb hlau oxides TiO2, Fe2O3, thiab lwm yam. Cov ntxhia muaj pes tsawg leeg yog feem ntau: mullite, cristobalite thiab quartz. , iav theem.
(2) Lub refractoriness feem ntau yog 1580 ~ 1750C, uas nce nrog qhov nce ntawm Al2O3 / SiO2. Thaum cov ntsiab lus ntawm low-melt impurities loj, cov refractoriness ntawm cov khoom txo qis heev.
(3) Lub softening kub nyob rau hauv load yog hais txog 1250 ~ 1450C, thiab nws variation ntau yog dav. Qhov pib deformation kub yog qis, txog 200 ~ 250C txawv ntawm 40 feem pua ntawm deformation kub.
(4) Lub coefficient ntawm linear expansion yog tsawg, thiab nws thermal conductivity kuj tsawg.
(5) Zoo thermal poob siab tsis kam thiab kev hloov pauv loj. 1100C dej txias lub voj voog feem ntau yog ntau tshaj 10 zaug. Qhov no muaj feem xyuam rau qhov qis coefficient ntawm linear expansion ntawm cov khoom siv av nplaum, cov nyhuv tsis tseem ceeb ntawm crystal transformation thiab plasticity ntawm qhov kub thiab txias.
(6) Cov tshuaj tiv thaiv kev yaig: Vim nws tsis muaj zog acidic, hluav taws kub caly cib muaj zog tiv thaiv acid slag yaig, tab sis tsis muaj zog tiv thaiv cov khoom alkaline yaig.
Ceramic fiber ntau daim pam lub ntsiab tivthaiv yog alumina, thiab ceramic fiber insulators yog haum rau hauv ob sab phlu rwb thaiv tsev ntawm ntau yam muaj kilns. Xws li bogie rauv, annealing rauv, coke qhov cub, galvanizing lauj kaub, qhov kiln, fais fab nroj tsuag, aluminium electrolytic cell, regenerative incinerator, beam cua sov rauv, laub-steel cua sov rauv, taws, ladle, ladle, nruam hloov kho rauv, tuav lub qhov, lwm.
