Hydrogen gas lub tog raj kheej

Lus piav qhia luv luv:

Lub tog raj kheej roj yog lub nkoj siab rau kev khaws cia thiab ntim cov pa roj ntawm qhov siab tshaj atmospheric siab.

High-pressure gas cylinders kuj hu ua lub raj mis.Nyob rau hauv lub tog raj kheej cov ntaub ntawv khaws cia yuav nyob rau hauv lub xeev ntawm compressed gas, vapor tshaj kua, supercritical kua, los yog yaj nyob rau hauv ib tug substrate khoom, nyob ntawm seb lub cev yam ntxwv ntawm cov khoom.

Ib txwm gan roj kheej tsim yog elongated, sawv ntsug ntawm flattened hauv qab kawg, nrog lub valve thiab haum rau sab saum toj rau kev siv cov apparatus.

Daim ntawv thov

1. Hauv kev lag luam petrochemical, hydrogenation yuav tsum tau ua kom zoo dua cov roj crude los ntawm desulfurization thiab hydrocracking.

2. Lwm qhov tseem ceeb ntawm kev siv hydrogen yog nyob rau hauv hydrogenation ntawm cov rog hauv margarine, roj ua noj, tshuaj zawv plaub hau, lubricants, tshuaj ntxuav tsev thiab lwm yam khoom.

3. Nyob rau hauv cov txheej txheem kub kub ntawm cov iav tsim thiab kev tsim hluav taws xob microchips, hydrogen yog ntxiv rau nitrogen tiv thaiv roj kom tshem tawm cov pa seem.

4. Nws yog siv los ua cov khoom siv raw rau kev sib txuas ntawm ammonia, methanol thiab hydrochloric acid, thiab ua tus neeg sawv cev txo qis rau metallurgy.

5. Vim muaj roj ntau ntawm hydrogen, kev lag luam aerospace siv kua hydrogen ua roj.

Cov ntsiab lus ntawm Hydrogen:

Hydrogen yog cov tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, nplaim taws thiab tawg, thiab muaj kev phom sij tawg thaum sib xyaw nrog fluorine, chlorine, oxygen, carbon monoxide thiab cua.Ntawm lawv, qhov sib xyaw ntawm hydrogen thiab fluorine yog nyob rau hauv qhov kub thiab txias.Ib puag ncig tuaj yeem tawg, thiab thaum sib xyaw ntim piv nrog cov roj chlorine yog 1: 1, nws tuaj yeem tawg hauv qab lub teeb.

Vim tias hydrogen tsis muaj xim thiab tsis muaj ntxhiab, nplaim taws yog pob tshab thaum hlawv, yog li nws lub neej tsis yooj yim los ntawm kev hnov qab.Feem ntau, cov ntxhiab tsw ethanethiol yog ntxiv rau hydrogen kom nws ntes tau los ntawm tsw thiab tib lub sijhawm muab xim rau cov nplaim taws.

Txawm hais tias hydrogen tsis muaj tshuaj lom, nws yog physiologically inert rau tib neeg lub cev, tab sis yog tias cov ntsiab lus hydrogen hauv huab cua nce, nws yuav ua rau hypoxic asphyxia.Raws li nrog rau tag nrho cov kua cryogenic, kev sib cuag ncaj qha nrog cov kua hydrogen yuav ua rau frostbite.Cov dej ntws tawm ntawm cov kua hydrogen thiab cov evaporation loj heev yuav ua rau tsis muaj oxygen nyob hauv ib puag ncig, thiab tuaj yeem tsim cov khoom sib xyaw nrog huab cua, ua rau muaj kev sib tsoo tawg.
