IHydrojeni (H2)

Iiparamitha zobugcisa

I-Hydrogen ine-formula yekhemikhali ye-H2 kunye ne-molecular weight ye-2.01588.Phantsi kobushushu obuqhelekileyo kunye noxinzelelo, yirhasi enokutsha ngokugqithisileyo, engenambala, ebonakalayo, engenavumba nengenancasa ekunzima ukuyinyibilikisa emanzini, kwaye ayisebenzi kwizinto ezininzi.Nangona kunjalo, phantsi koxinzelelo oluphezulu kunye neemeko zobushushu obuphakathi, i-hydrogen isabela ngezinto ezininzi ze-hydrocarbon kwi-catalytic reaction.IHydrojeni yeyona gesi ixineneyo incinci eyaziwayo ehlabathini.Ubuninzi be-hydrogen yi-1/14 kuphela yomoya, oko kukuthi, kwi-atmosphere ye-1 eqhelekileyo kunye ne-0 ° C, ubuninzi be-hydrogen yi-0.089g/L.IHydrojeni yeyona nto iphambili kwimveliso.Amashishini epetroleum kunye neekhemikhali afuna isixa esikhulu se-hydrogen.Phakathi kwabo, ukuqhutyelwa kwamafutha e-fossil kunye nokuveliswa kwe-ammonia yinkqubo ye-Hubble zicelo eziphambili.Ukongeza ekusebenziseni imichiza, ihydrogen ikwanoluhlu olubanzi lwezinto ezisetyenziswayo kwifiziksi nobunjineli.Ingasetyenziswa njengerhasi yokukhusela kwezinye iindlela ze-welding.I-Hydrogen ikwayigesi ebalulekileyo kwimizi-mveliso kunye negesi ekhethekileyo, kwaye inoluhlu olubanzi lwezicelo kwishishini le-elektroniki, ishishini lesinyithi, ukulungiswa kokutya, iglasi edadayo, i-organic synthesis, i-aerospace, njl. amandla esibini afanelekileyo (amandla esibini abhekisele kumandla ekufuneka eveliswe kumandla okuqala afana namandla elanga, amalahle, njl. njl.) kunye nesibaso serhasi.Itshisa njengedangatye elicacileyo, ekunzima ukulibona.Amanzi kuphela kweeMveliso zokutsha.I-Hydrogen inokusetyenziswa njengento ekrwada ye-synthetic ammonia, i-synthetic methanol, kunye ne-synthetic hydrochloric acid, njenge-arhente yokunciphisa i-metallurgy, kunye ne-agent ye-hydrodesulfurization kwi-petroleum refining.Ngenxa yokuba ihydrogen iyigesi exineneyo enokutsha, kufuneka igcinwe kwindawo epholileyo nengena umoya.Iqondo lobushushu kwindawo yokugcina impahla akufanele lidlule kwi-30°C.Zigcine kude nomlilo kunye nemithombo yobushushu.Kuphephe ukukhanya kwelanga.Kufuneka igcinwe ngokwahlukileyo kwi-oksijeni, umoya oxinyiweyo, i-halogens (i-fluorine, i-chlorine, i-bromine), i-oxidants, njl.Ukukhanyisa, ukungena komoya kunye nezinye izixhobo kwindawo yokugcina kufuneka kube nokuqhuma, kunye nokutshintsha okungaphandle kwendawo yokugcina impahla, kwaye kuxhotywe ngeentlobo ezihambelanayo kunye nobuninzi bezixhobo zokucima umlilo.Ukuthintela ukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo ezithandwa ziintlantsi

Isicelo:

①Ukusetyenziswa koShishino:

Kwinkqubo yokuvelisa iglasi yobushushu obuphezulu kunye nokuveliswa kwee-microchips ze-elektroniki.

②Ukusetyenziswa kwezonyango:

Nikezela ukunyanga iintlobo zezifo, ezifana nethumba, istroke.

③Kukwenziwa kwesemiconductor:

Irhasi yokuthwala, ngakumbi i-silicon deposition gas chromatography.

Iphakheji eqhelekileyo:

I-advanteji:

① Ngaphezu kweminyaka elishumi kwimarike;

②ISO umenzi wesatifikethi;

③Ukuhanjiswa ngokukhawuleza;

④Umthombo wemathiriyeli ekrwada;

⑤Inkqubo yokuhlalutya kwi-intanethi yokulawula umgangatho kwinqanaba ngalinye;

⑥Imfuno ephezulu kunye nenkqubo enobuchule yokuphatha isilinda ngaphambi kokuzaliswa;
