Sulfur dioxide (SO2)

Usoro nka

Sulfur dioxide (sulfur dioxide) bụ sọlfọ oxide nke a na-ahụkarị, dị mfe na nke na-akpasu iwe nwere usoro kemịkalụ SO2.Sulfur dioxide bụ gas na-enweghị ụcha na nke nwere isi na-esi ísì ụtọ.Na-agbaze n'ime mmiri, ethanol na ether, sọlfọ sulfur dioxide na-adịtụ mma, adịghị arụ ọrụ, enweghị ọkụ, ọ dịghịkwa emepụta ngwakọta mgbawa na ikuku.Sulfur dioxide nwere mmetụta ịcha ọcha.A na-ejikarị sọlfọ dioxide eme ihe na ụlọ ọrụ iji ihicha pulp, ajị anụ, silk, okpu ahịhịa, wdg. Sulfur dioxide nwekwara ike igbochi uto nke ebu na nje bacteria.Enwere ike iji ya dị ka ihe nchekwa n'ụdị nri dị iche iche dị ka mkpụrụ osisi a mịrị amị, akwụkwọ nri pickled, na ngwaahịa anụ emebere (dị ka sausaji na hamburgers), mana ọ ga-abụrịrị nke ọma dabere na mpaghara mba dị mkpa na ojiji ọkọlọtọ.A na-ejikwa Sulfur dioxide mee ihe dị ka ihe mgbaze organic na refrigerant, ma na-eme ka mmanụ dị iche iche na-esi ísì ụtọ;eji emepụta sulfur trioxide, sulfuric acid, sulfite, thiosulfate, ma na-ejikwa ya dị ka fumigant, preservative, disinfectant, na mbenata ihe Etc.;eji na mmepụta nke sọlfọ na dị ka pesticides na fungicides.Akpachara anya na-arụ ọrụ: mechiri emechi nke ọma, na-enye ikpochapụ mpaghara zuru oke yana ikuku ikuku zuru oke.Ndị na-arụ ọrụ ga-enwerịrị ọzụzụ pụrụ iche ma rube isi na usoro ọrụ.A na-atụ aro ka ndị na-arụ ọrụ na-eyi ihe mkpuchi gas nzacha nke onwe (ihe mkpuchi ihu zuru oke), uwe mkpuchi gas na teepu, na uwe rọba.Wepụ n'ebe ọkụ na ebe ikpo ọkụ na-esi na ya pụta, na ịṅụ sịga ka amachibidoro n'ebe ọrụ.Wepụ ihe ndị na-ere ọkụ na ọkụ.Gbochie gas ma ọ bụ uzuoku ịba n'ime ikuku ebe ọrụ.Zere ịkpọtụrụ ndị ọrụ na-ebelata.Were obere ibu ma butuo ya n'oge njem iji gbochie mmebi nke cylinders na ngwa.Ejikọtara ya na ụdị na ọnụ ọgụgụ nke ngwa mgbanyụ ọkụ na mgbapụ ngwa ngwa ọgwụgwọ mberede.Akpachara anya nchekwa: Chekwaa n'ụlọ nkwakọba ihe dị jụụ, ikuku ikuku.Wepụ ọkụ na isi mmalite okpomọkụ.Okpomọkụ nchekwa ekwesịghị gafere 15 Celsius.Ekwesịrị ịchekwa ya iche site na ihe ọkụ ọkụ (na-agba ọkụ), na-ebelata ihe ndị na-ebelata, na kemịkalụ oriri, ma zere ịgwakọta ha.Ebe nchekwa ahụ kwesịrị ịnwe akụrụngwa ọgwụgwọ ihe mberede na-agbapụta.

Ngwa:

① Ihe na-ebute sulfuric acid:

Sulfur dioxide bụ ihe etiti na mmepụta nke sulfuric acid, a na-atụgharị ya na sulfur trioxide, wee ghọọ oleum, nke a na-eme ka ọ bụrụ sulfuric acid.

② Dị ka onye na-ebelata ihe nchekwa:

A na-eji sọlfọ dioxide eme ihe mgbe ụfọdụ dị ka ihe nchekwa maka apricots a mịrị amị, fig a mịrị amị, na mkpụrụ osisi ndị ọzọ a mịrị amị, ọ bụkwa ezigbo mbelata.

③ Dị ka ihe refrigerant:

N'ịbụ ndị na-adị mfe condensed na inwe nnukwu okpomọkụ nke evaporation, sulfur dioxide bụ ihe ndoro-ndoro maka refrigerant.

Ngwungwu nkịtị:

 Uru:

① Ihe karịrị afọ iri na ahịa;

② onye nrụpụta akwụkwọ ISO;

③ nnyefe ngwa ngwa;

④ Isi iyi akụrụngwa siri ike;

⑤ Usoro nyocha nke ntanetị maka njikwa mma na usoro ọ bụla;

⑥ High chọrọ na usoro nlezianya maka ijikwa cylinder tupu ejuputa;
