Sulfur Dioxide (SO2)

Technical parameters

Sulfur dioxide (sulfur dioxide) yog qhov feem ntau, yooj yim, thiab khaus sulfur oxide nrog cov tshuaj formula SO2. Sulfur dioxide yog cov roj tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw. Soluble hauv dej, ethanol thiab ether, kua sulfur dioxide yog qhov ruaj khov, tsis muaj zog, tsis muaj hluav taws xob, thiab tsis tsim cov khoom tawg nrog huab cua. Sulfur dioxide muaj cov khoom bleaching. Sulfur dioxide feem ntau yog siv rau hauv kev lag luam rau tshuaj dawb pulp, ntaub plaub, txhob lo lo ntxhuav, kaus mom straw, thiab lwm yam. Sulfur dioxide tuaj yeem cuam tshuam kev loj hlob ntawm pwm thiab kab mob. Nws tuaj yeem siv los ua cov khoom noj khoom haus sib txawv xws li cov txiv hmab txiv ntoo qhuav, cov txiv hmab txiv ntoo qhuav, thiab cov khoom siv nqaij ua tiav (xws li cov hnyuv ntxwm thiab hamburgers), tab sis nws yuav tsum nruj me ntsis raws li cov kev cai hauv lub tebchaws thiab kev siv Standard. Sulfur dioxide kuj yog siv los ua cov kuab tshuaj organic thiab cov tub yees, thiab siv los ua kom cov roj lubricating ntau dua; siv los tsim sulfur trioxide, sulfuric acid, sulfite, thiosulfate, thiab tseem siv los ua fumigant, preservative, tshuaj tua kab mob, thiab txo tus neeg sawv cev thiab lwm yam.; siv rau hauv kev tsim cov sulfur thiab ua tshuaj tua kab thiab fungicides. Kev ceev faj txog kev ua haujlwm: kaw nruj nreem, muab cov pa tawm hauv zos txaus thiab ua kom dav dav. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav lub qhov ncauj qhov ntswg rau tus kheej (cov npog ntsej muag tag nrho), cov khaub ncaws tiv thaiv roj hmab, thiab hnab looj tes roj hmab. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov, thiab kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm. Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws kub. Tiv thaiv kom tsis txhob muaj roj lossis vapors los ntawm kev nkag mus rau hauv huab cua hauv chaw ua haujlwm. Tsis txhob tiv tauj nrog cov neeg ua haujlwm txo qis. Yooj yim thauj khoom thiab tshem tawm thaum thauj mus los kom tsis txhob muaj kev puas tsuaj rau lub tog raj kheej thiab cov khoom siv. Nruab nrog cov hom sib xws thiab ntau ntawm cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm ceev. Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Qhov ntsuas kub yuav tsum tsis pub tshaj 15 ° C. Nws yuav tsum tau muab cais los ntawm cov khoom siv hluav taws xob yooj yim (combustible) combustibles, txo cov neeg ua hauj lwm, thiab cov tshuaj noj tau, thiab tsis txhob sib tov. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Precursor rau sulfuric acid:

Sulfur dioxide yog ib qho nruab nrab hauv kev tsim cov sulfuric acid, hloov mus rau sulfur trioxide, thiab tom qab ntawd mus rau oleum, uas tau ua rau sulfuric acid.

② Raws li tus neeg saib xyuas kev noj qab haus huv:

Sulfur dioxide yog qee zaum siv los ua cov tshuaj tiv thaiv rau qhuav apricots, figs qhuav, thiab lwm yam txiv hmab txiv ntoo qhuav, nws kuj yog ib qho zoo reductant.

③ Raws li lub tub yees:

Ua tau yooj yim condensed thiab muaj cua kub ntawm evaporation, sulfur dioxide yog cov khoom siv rau cov tub yees.
