● Dej tsis kam

Rockwool tsis tshua muaj 2Cao thiab SiO2, yog li nws cov khoom tiv thaiv ntau dua li cov ntaub plaub ntxhia.Muaj qhov sib txawv loj ntawm pob zeb wool thiab ntxhia wool rau PH tus nqi, pob zeb wool feem ntau tsawg dua 4, tshwj xeeb tshaj yog dej-resistant ntxhia fiber ntau;mineral wool feem ntau ntau dua 5, los yog ntau tshaj 6, nws cov dej tsis kam tsuas yog nyob nruab nrab lossis tsis ruaj khov.Vim tias qhov sib txawv ntawm lawv, cov ntaub plaub ntxhia yuav tsum tsis txhob siv rau hauv cov dej ntub dej, tshwj xeeb tshaj yog nyob rau hauv qhov project txias rwb thaiv tsev.Nyob rau hauv qhov project rwb thaiv tsev txias, cov kev taw qhia ntawm tshav kub ntws yog los ntawm sab nraud ntws mus rau sab hauv, thiab rwb thaiv tsev engineering cua sov ntws yog nyob rau hauv opposite kev taw qhia.Sab nraum cov dej noo yuav nkag mus rau cov khoom siv rwb thaiv tsev txias sab hauv nrog qhov kub thiab txias, dew yuav condenses rau hauv dej, yog tias siv cov ntxhia wool nyob rau hauv cov xwm txheej no, cov fiber ntau yuav maj mam rhuav tshem hydration, txo lub neej ntawm cov txheej txheem txias txias. tsis muaj qhov tsis txaus no.Yog li ntawd rau lub tsev rwb thaiv tsev system tsuas yog siv pob zeb wool li rwb thaiv tsev cov ntaub ntawv.

● Kub kub tsis kam

Thaum cov ntxhia wool ua haujlwm kub txog 675 ℃, vim nws lub cev hloov pauv, nws qhov ntom yuav me dua thaum nws ntim loj dua, tom qab ntawd cov ntaub plaub ntxhia pib pulverization thiab tawg.Yog li cov ntxhia wool ua haujlwm kub yuav tsum tsis txhob siab tshaj 675 ℃.Yog li ntawd, cov ntxhia wool tsis tuaj yeem siv rau hauv cov tsev thiab kev tsim kho.

Thaum lub pob zeb ntaub plaub tsis muaj qhov teeb meem no, qhov ua haujlwm kub tuaj yeem ncav cuag 800 ℃, txawm hais tias lub ntsiab lus tseem ceeb CS-C2-AS-CAS2 eutectic point yog 1265 ℃, nws qhov kub thiab txias kuj tuaj yeem ncav cuag 900 ℃ -1000 ℃.

● Corrosion kuj

Lub luag haujlwm tseem ceeb ntawm blasting furnace smelting ntawm cam khwb cia hlau yog tshem tawm feem ntau ntawm cov sulfur los tiv thaiv tshav kub tsim nyob rau hauv chav kawm ntawm qhov tshwm sim tsis yooj yim.Kev tshem tawm cov sulfur yuav nyob twj ywm hauv qhov cub li calcium sulfide (CaS).Hauv kev tsim cov ntxhia wool, qhov no ntawm CaS yuav tom qab mus rau hauv cov ntaub plaub, uas cov ntsiab lus yog kwv yees li 5%.

Pob zeb wool raw cov ntaub ntawv feem ntau yog basalt los yog diabase, tshwj tsis yog muaj me ntsis sulfur coj los ntawm coke thaum smelting, tsis muaj ntau qhov chaw ntawm leej faj, yog li nws tsis muaj corrosive rau hlau.
