Thib ob, aluminium dross yog tshuav tsis kho cuam tshuam rau hauv kev ua haujlwm microbial hauv cov khib nyiab thiab ignitelossis pyrolysize ib puag ncig cov khoom pov tseg. Cov tshuaj lom neeg muaj feem xyuam nrog txhuas tuaj yeem tso tawm ntau cov tshuaj lom thiab / lossis cov pa taws uas tuaj yeem ua rau muaj kuab paug ntau dua.
Dross yog dab tsi?
Dross yog ib pawg ntawm khoom impurities ntab rau ntawm cov hlau molten lossis tawg hauv cov hlau, xws li hauv cov hlau wrought. Nws tsim nyob rau saum npoo ntawm cov hlau uas tsis tshua muaj melting point xws li tin, lead, zinc los yog txhuas los yog alloys los ntawm oxidation ntawm cov hlau.
Vim li cas aluminium dross toxic?
Nws yog vim cov txhuas slat slag yog qhov yooj yim rau leaching chlorides thiab tso tawm cov ntxhiab tsw tsw ntxhiabxws li methane, ammonia, phosphide, thiab hydrogen sulphide thaum sib cuag nrog dej [16].
Dross siv rau dab tsi?
Dross yog ib pawg ntawm cov khoom impurities ntab rau ntawm cov hlau molten. Nws tsis yog tag nrho cov khoom pov tseg; aluminium dross, piv txwv li, tuaj yeem rov ua dua thiab siv hauv secondary steelmaking rau slag deoxidation.
Dross ib slag?
Dross yog ib yam khoom uas txawv ntawm slag, uas yog kua. Dross khoom tsis yog tag nrho cov khoom pov tseg; aluminium dross, piv txwv li, tuaj yeem rov ua dua thiab siv rau hauv cov hlau theem nrab ua rau slag deoxidation.
