I-Sulfur Dioxide (SO2)

Imingcele yezobuchwepheshe

I-sulphur dioxide (i-sulphur dioxide) i-sulphur oxide evame kakhulu, elula, futhi ecasulayo enefomula yamakhemikhali ethi SO2. I-Sulfur dioxide igesi engenambala futhi esobala nephunga elimnandi. Incibilika emanzini, i-ethanol ne-ether, i-liquid sulphur dioxide izinzile, ayisebenzi, ayishi, futhi ayakhi ingxube eqhumayo nomoya. I-Sulfur dioxide inezindawo zokufiphaza. I-Sulfur dioxide ivame ukusetshenziswa embonini ukwenza uketshezi olumhlophe lwe-pulp, uvolo, usilika, izigqoko zotshani, njll. I-Sulfur dioxide ingavimbela ukukhula kwesikhunta namagciwane. Ingasetshenziswa njengesivikelo ezinhlotsheni ezihlukene zokudla njengezithelo ezomisiwe, imifino efakwe emanzini anosawoti, nemikhiqizo yenyama egayiwe (njengamasoseji nama-hamburgers), kodwa kufanele ihambisane ngokuqinile nobubanzi bukazwelonke obufanele kanye nokusetshenziswa Okujwayelekile. I-Sulfur dioxide iphinde isetshenziswe njenge-solvent ne-refrigerant ephilayo, futhi isetshenziselwa ukucwenga amafutha okugcoba ahlukahlukene; esetshenziselwa ukukhiqiza i-sulfur trioxide, i-sulfuric acid, i-sulfite, i-thiosulfate, iphinde isetshenziswe njenge-fumigant, i-preservative, i-disinfectant, ne-ejenti yokunciphisa njll.; esetshenziswa ekukhiqizeni isulfure nanjengama-pesticides nama-fungicides. Izinyathelo zokuphepha: ivalwe ngokuqinile, ihlinzeka ngokukhipha umoya okwanele kwendawo kanye nokungena komoya okuphelele. Abasebenzisi kufanele baqeqeshwe ngokukhethekile futhi balandele ngokuqinile izinqubo zokusebenza. Kutuswa ukuthi o-opharetha bagqoke izifihla-buso zegesi yokuhlunga (izifihla-buso ezigcwele ubuso), izingubo zokuvikela igesi yetheyiphu, namagilavu ​​enjoloba. Ziqhelelanise nemithombo yomlilo neyokushisa, futhi ukubhema kwenqatshelwe ngokuphelele emsebenzini. Gwema ezintweni ezivuthayo nezivuthayo. Vimbela igesi noma umhwamuko ukuthi ungavuzi emoyeni wasemsebenzini. Gwema ukuthintana nabanciphisi. Layisha futhi ukhiphe kancane ngesikhathi sokuthutha ukuze uvimbele ukulimala kumasilinda nezinsiza. Ifakwe izinhlobo ezihambisanayo namanani ezinto zokucisha umlilo kanye nempahla yokwelapha eziphuthumayo evuzayo. Imithetho yesitoreji: Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-15°C. Kufanele igcinwe ngokuhlukana nezinto ezikwazi ukuvutha kalula (ezivuthayo), ezenza ukunciphisa, namakhemikhali adliwayo, futhi kugwenywe ukukuxuba. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

①Isandulela se-sulfuric acid:

I<em>sulfur dioxide iyindawo ephakathi ekukhiqizeni i<em>sulfuric acid, iguqulwa ibe yi<em>sulfur trioxide, bese iba yi<em>oleum, eyenziwa ibe yi<em>sulfuric acid.

②Njenge-ejenti yokunciphisa isilondolozi:

Ngezinye izikhathi i-sulphur dioxide isetshenziswa njengesilondolozi samabhilikosi omisiwe, amakhiwane omisiwe, nezinye izithelo ezomisiwe, futhi iyisinciphisi esihle.

③Njengesiqandisi:

Njengoba ijiya kalula futhi inokushisa okuphezulu kokuhwamuka, i-sulphur dioxide iyinto esetshenziswa eziqandisini.

Iphakheji evamile:

 Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
