Okokuqala, uhlobo lwe-nitrogen

I-Nitrogen, phantsi kweemeko eziqhelekileyo, igesi engenambala, engenancasa, engenavumba kwaye idla ngokuba ayinayo ityhefu.I-nitrogen yenza i-78.12% ye-atmosfera iyonke (iqhezu lomthamo).Kubushushu obuqhelekileyo, yigesi.Kuxinzelelo oluqhelekileyo lwe-atmospheric, iba lulwelo olungenambala xa lupholile ukuya ku -195.8℃.Xa ipholile ukuya ku -209.86℃, initrogen engamanzi iba yinto eqinileyo efana nekhephu.Ukusetyenziswa: i-chemical synthesis (i-nylon yokwenziwa, i-acrylic fiber, i-resin yokwenziwa, i-rubber yokwenziwa kunye nezinye izinto ezibalulekileyo ezibonakalayo), amathayi eemoto (i-nitrogen inokunciphisa ngokufanelekileyo ingxolo yamavili, yandise ubomi benkonzo yamavili).Ngenxa yokuba initrogen ingasebenzi ngokwemichiza, idla ngokusetyenziswa njengegesi ekhuselayo, njengemelon, iziqhamo, ukutya, kunye negesi yokuzalisa ibhalbhu.

Eyesibini, ukusetyenziswa kwenitrogen

I-Nitrogen kwi-metallurgy, ishishini lemichiza, ishishini lokukhanya, i-electronics kunye namanye amasebe, njengegesi yokutya, igesi ekhuselayo, igesi yokutshintshwa kunye negesi yokutywina.Iimveliso zenitrogen yolwelo nazo zisetyenziswa kakhulu ekutyeni okukhenkcezileyo, imifuno kunye nokugcinwa kweziqhamo.Ikwasetyenziswa ngokubanzi kwezolimo kunye nokufuya izilwanyana, ezifana insecticidal ukugcinwa okuziinkozo, engumkhenkce yokugcina amadlozi imfuyo eliphezulu, etc. Ngaba constituent of iiproteni kwizityalo kunye nezilwanyana.

Ngenkqubela phambili yesayensi kunye nobuchwepheshe kunye nophuhliso loqoqosho, umthamo wokusetyenziswa kwenitrogen uyanda imihla ngemihla.

Thatha ithuba le-inetia yenitrogen

Ukugcinwa kokutya: ukutya, iziqhamo (iziqhamo), imifuno kunye nokunye ukugcinwa kwe-air conditioning kunye nokugcinwa, inyama, ushizi, isardadi, iti kunye nekhofi, njengokupakishwa okutsha, i-jam, njengokugcinwa kwe-nitrogen oxygenation, iibhotile ezahlukeneyo zokuhlanjululwa kwewayini kunye nokugubungela, njl.

Imboni yamachiza: iyeza laseTshayina (ginseng) i-nitrogen yokuzalisa ukugcinwa kunye nokugcinwa, i-western drug injection nitrogen filling, itanki yokugcina kunye ne-container nitrogen yokuzalisa i-oksijini, ukuhanjiswa kwe-pneumatic yeziyobisi yomthombo womoya, njl.

Ishishini leMichiza: ukutshintshwa, ukucocwa, ukutywinwa, ukufumanisa ukuvuza kunye nokukhuselwa kwegesi, ukucima okomileyo, ukuvuselelwa kwe-catalyst, i-petroleum fractionation, imveliso yefiber yekhemikhali, njl.

Ishishini lezichumisi: imathiriyeli ekrwada yesichumiso senitrogen.Ikopi yokukhusela i-Catalyst, igesi yokuhlamba, njl.

Ishishini lePlastiki: ukuhanjiswa kwepneumatic kwamasuntswana eplastiki, ukuveliswa kweplastiki kunye nokuthintela ukugcinwa kwe-oxidation.

Ishishini lerabha: ukupakishwa kwerabha kunye nokugcinwa, ukuveliswa kwamatayara, njl.

Ishishini leglasi: Irhasi ekhuselayo yenkqubo yokuvelisa iglasi edadayo.

Imboni yePetroleum: ukuzaliswa kwe-nitrogen kunye nokuhlanjululwa kokugcinwa, izitya, iinqaba ze-catalytic kunye nemibhobho, ukufunyaniswa kokuvuza koxinzelelo lweenkqubo zokulawula, njl.

Uphuhliso lwe-oyile ekude nonxweme: ukugqunywa kwerhasi kumaqonga e-oyile aphesheya konxweme, inaliti yenitrogen yokubuyisela i-oyile, itanki kunye nokufaka isikhongozeli, njl.

Ukugcinwa kweqhuma: ukuthintela i-cellar, ishedi kunye nenye indawo yokugcina uthuli oluvuthayo oluvuthayo kunye nokudubula, njl.

Ukuthumela: i-oil tanker yokucoca igesi, njl.
