Cov Txheej Txheem Ntau Lawm
Cov khoom siv roj av (cov kua roj acid) yauv ua kom muaj kev hloov pauv roj los tig hydrogen sulfide rau hauv cov leej faj, thiab cov roj tsis tau raug rho tawm rov qab los oxidized. Cov kua dej kua roj ntses kua cais tawm ntawm cov ntxiab yog pelletized, pwm thiab ntim rau kev xa tawm.
Khoom ua tau zoo
Sulphur yog cov khoom daj, muab faib ua cov duab crystalline thiab amorphous. Melting point 112.8 ～ 119.3 ℃, kub taw tes 444.6 ℃, insoluble hauv dej, soluble me ntsis hauv cawv thiab ethers, yooj yim soluble hauv carbon dioxide, carbon tetrachloride thiab benzene. Cov khoom no yog Chav Kawm Khoom uas kub hnyiab tau nrog qhov xeb ntawm 205 ° C. Nws cov plua plav lossis dej tuaj yeem ua rau tawg tau sib tov nrog huab cua. Nws yog cov nplaim taws cov khoom lag luam phom sij.
Khoom Siv Pab
Sulphur siv feem ntau los tsim sulfuric acid, dyes, foob pob hluav taws thiab cov khoom siv roj hmab, thiab tseem tuaj yeem siv rau hauv kev lag luam tub rog, tshuaj, thiab tshuaj tua kab. Cov zaub mov sulfur tuaj yeem siv rau cov tshuaj tua kab mob, tshuaj tua kab, tshuaj dawb, ua paug, thiab lwm yam hauv kev lag luam khoom noj khoom haus. Nws kuj tseem siv tau los muag pob kws thiab lwm yam ntaub ntawv nyoos hauv kev lag luam hmoov txhuv nplej siab. Cov leej faj cov pa uas tsim los ntawm cov txheej txheem no yog tshwj xeeb rau cov foob pob hluav taws, kev lag luam tub rog, thiab kev lag luam kws kho mob, ntxiv rau cov tshuaj dawb thiab fumigation.
