Carbon dioxide (CO2)

Usoro nka

Carbon dioxide, ụdị carbon oxygen compound, nke nwere usoro kemịkalụ CO2, bụ gas na-enweghị isi, enweghị isi ma ọ bụ enweghị isi nke nwere uto utoojoo na ngwọta mmiri ya n'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị. Ọ bụkwa gas na-ekpo ọkụ na-emekarị na akụkụ nke ikuku. Otu (na-aza 0.03%-0.04% nke mkpokọta olu ikuku). N'ihe gbasara akụrụngwa anụ ahụ, carbon dioxide bụ gas na-enweghị ụcha na enweghị isi n'ime ụlọ okpomọkụ na nrụgide. Ọ nwere njupụta dị elu karịa ikuku ma soluble na ọtụtụ ihe mgbaze organic dị ka mmiri na hydrocarbons. N'ihe gbasara akụrụngwa kemịkalụ, otu n'ime carbon dioxide carbon oxygen ogige bụ ihe inorganic. Ọ naghị arụ ọrụ kemịkalụ ma nwee nkwụsi ike dị elu (naanị 1.8% ire ere na 2000 Celsius). Ọ nweghị ike ire ọkụ, ọ naghị akwado combustion, yana acidic. Oxides nwere otu ihe dị ka acidic oxides. N'ihi na ha na-eji mmiri emeghachi omume iji mepụta carbonic acid, ha bụ anhydrides nke carbonic acid. Banyere nsị ya, ọmụmụ egosila na carbon dioxide na-etinye obere uche abụghị ihe na-egbu egbu, ebe nnukwu carbon dioxide nwere ike imebi anụmanụ. A na-ejikarị carbon dioxide dị ọcha na ụlọ ọrụ eletrọnịkị, nyocha ahụike na nyocha ụlọ ọgwụ, laser carbon dioxide, gas calibration maka ngwa ule na nkwadebe nke gas ndị ọzọ agwakọtara pụrụ iche, a na-ejikwa ya dị ka onye na-achịkwa na polyethylene polymerization. A na-eji carbon dioxide gas eme ihe maka ihe ọṅụṅụ dị nro carbonized, njikwa pH na usoro ọgwụgwọ mmiri, nhazi kemịkalụ, nchekwa nri, nchebe inert na nhazi kemịkalụ na nri, ịgbado ọkụ gas, ihe na-akpali akpali nke osisi, nke a na-eji na-eme ka ebu na cores sie ike ma jiri ya mee ihe na nkedo Pneumatic ngwaọrụ. A na-ejikwa ya dị ka ihe na-esi ísì ụtọ maka gas sterilization (ya bụ, ngwakọta nke ethylene oxide na carbon dioxide ka a na-eji dị ka igba ogwu, ọgwụ ụmụ ahụhụ, na fumigant.

A na-eji carbon dioxide mmiri mmiri mee ihe dị ka friji, ule dị ala nke ụgbọ elu, ngwa agha na ngwa eletrọnịkị, iji meziwanye mgbake nke ọma mmanụ, polishing roba na njikwa mmeghachi omume kemịkal, a pụkwara iji ya mee ihe dị ka onye na-emenyụ ọkụ.

Ngwa:

① Ojiji ụlọ ọrụ:

A na-ejikarị carbon dioxide dị ọcha na ụlọ ọrụ eletrọnịkị, nyocha ahụike na nyocha ụlọ ọgwụ, laser carbon dioxide, gas calibration maka ngwa ule na nkwadebe nke gas ndị ọzọ agwakọtara pụrụ iche, a na-ejikwa ya dị ka onye na-achịkwa na polyethylene polymerization.

②Refrigerant na emenyụ:

A na-eji carbon dioxide mmiri mmiri mee ihe dị ka refrigerant maka ule dị ala nke ụgbọ elu, ngwa agha na ngwa eletrọnịkị, enwere ike iji ya dị ka ihe na-emenyụ ọkụ.
