1. Cov nyhuv siv yog txawv.
Lub pob zeb wool lub cev tsis muaj leej faj dawb, thiab cov ntsiab lus ntawm lub pob slag yog qis dua li cov ntxhia wool. Txawm li cas los xij, cov khoom siv pob zeb wool feem ntau siv hydrophobic resin ua cov ntaub ntawv. Cov resin muaj kev kho kom zoo, yog li qhov nqus dej noo tsawg thiab cov dej tsis kam yog siab dua li cov ntxhia wool. Qhov siab tshaj plaws ua haujlwm kub ntawm cov ntaub plaub yog 600 ~ 650 degrees Celsius. Feem ntau, fiber ntau ntawm cov khoom yog tuab thiab luv dua. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm pob zeb wool tuaj yeem ncav cuag 900 ~ 1000 degrees Celsius, cov fiber ntau ntev, thiab cov tshuaj siv tau zoo dua li cov ntxhia wool, tab sis cov nqi ntawm cov pob zeb wool yog siab dua li cov ntxhia wool.
2. Cov txheej txheem ntau lawm yog txawv.
Cov txheej txheem tsim khoom ntawm cov khoom siv pob zeb yog ua kom sov ncaj qha xws li basalt lossis diabase thiab ib qho me me ntawm dolomite, limestone lossis cocoonite thiab lwm yam khoom ntxiv rau hauv lub xeev molten ntawm qhov kub ntawm 1400 txog 1500 degrees hauv lub cubola cub tawg, thiab tom qab ntawd siv plaub-nyiaj centrifuge los tsim fibers. , tib lub sij hawm, dej-soluble resin los yog silicone thiab lwm yam adhesives yog sprayed rau saum npoo ntawm fiber, thiab ces tsim los ntawm sedimentation thiab siab. Cov roj plua plav pov thawj kuj tseem tuaj yeem txau rau ntawm qhov chaw ntawm cov khoom, thiab tom qab ntawd qhuav, veneered, stitched thiab kho kom ua tau ntau yam khoom siv pob zeb. Mineral wool feem ntau yog ua los ntawm slag los ntawm blast furnace ironmaking, nrog rau qee yam ntawm limestone lossis dolomite thiab tawg cib ntxiv. Nws yog melted nyob rau hauv ib lub khob los yog cellar ntawm qhov kub thiab txias me ntsis tshaj li melting kub ntawm pob zeb ntaub plaub, thiab yog tshuab los yog centrifuged. Txoj kev ua kom nws fiber ntau, thiab tshem tawm cov pob slag thiab impurities hauv fiber ntau los ntawm kev sib cais ntawm huab cua lossis dej.
