Gas Taw Qhia

Hydrogen, nrog rau cov tshuaj formula H₂, nyob rau hauv thawj lub sij hawm ntawm lub ntsiab lus. Nws yog diatomic gas molecule tsim los ntawm ob lub hydrogen atoms uas sib koom ib khub ntawm electrons. Hydrogen yog qhov tsawg tshaj plaws molecule thiab lub teeb tshaj roj nyob rau hauv cov xwm, nrog ib tug ceev tsuas yog ib tug - kaum plaub ntawm cov huab cua. Nws yog xim tsis muaj xim thiab tsis muaj ntxhiab, tseem muaj nplaim taws heev, yog li yuav tsum tau ceev faj thaum siv.

Raws li thaum ntxov xyoo pua 16th, Paracelsus, ib tug kws kho mob Swiss, sib tov hlau filings nrog acid thiab tau ib tug combustible gas, uas yog hydrogen. Txawm li cas los xij, nws tsis ua tiav kev tshawb fawb ntxiv rau nws thiab tsis muaj lub sijhawm los sau tseg hauv keeb kwm ntawm kev tshawb nrhiav tshuaj lom neeg.

Nyob rau hauv lub xyoo pua 17th, Jan Baptist van Helmont, ib tug kws tshawb fawb Belgian, kuj tau ntsib nrog hydrogen los ntawm lub caij nyoog, tab sis nws tsis cais, sau lossis kawm. Robert Boyle, tus kws tshuaj Askiv Askiv, ib zaug tau sau cov pa roj no ib yam nkaus, nws tseem tsis tau ua cov kev tshawb fawb cuam tshuam.

Nws yog Henry Cavendish, tus kws tshuaj Askiv Askiv, uas tau txeeb lub sijhawm. Nyob rau hauv 1766, thaum lub sij hawm kev sim, Cavendish yuam kev poob cov nplooj ntawv hlau rau hauv hydrochloric acid tov thiab pom muaj coob tus npuas tsim nyob rau hauv cov tshuaj. Qhov no tshwm sim tam sim ntawd aroused nws muaj zog txaus siab. Nws sau cov pa roj los ntawm txoj kev hloov dej thiab ua hauv - kev tshawb fawb tob. Ib qho kev sim ntawm kev tshawb pom tau pom tias cov pa roj yuav tawg thaum sib xyaw nrog huab cua thiab raug rau lub txim qhib, thiab nws yuav tsim dej tom qab hlawv hauv huab cua.

Raws li thawj tus neeg los sau thiab ua haujlwm kawm hydrogen, Cavendish tau lees paub thoob plaws ntiaj teb raws li tus neeg tshawb pom ntawm hydrogen hauv keeb kwm ntawm chemistry. Txawm li cas los xij, cuam tshuam los ntawm phlogiston txoj kev xav, nws ib zaug suav tias cov pa hluav taws xob zoo li phlogiston.

Nws tsis yog txog xyoo 1787 uas Antoine Lavoisier, tus kws tshuaj Fab Kis Fab Kis, tau txiav txim siab tias hydrogen ua cov tshuaj lom neeg. Txij li thaum hydrogen tsim cov dej tom qab combustion, nws hu ua cov pa hluav taws xob "hydrogen", uas txhais tau tias tsim cov dej.

Hydrogen tuaj yeem siv los ua cov roj av, hauv cov roj av refining, thiab hauv kev tsim cov khoom qab zib xws li roj thiab roj tawv. Nws kuj yog siv rau kev sib txuas ntawm methanol, hydrochloric acid, ammonia thiab lwm yam tshuaj, vuam thiab hlau txiav, kev soj ntsuam huab cua, iav melting, thiab metallurgical kev lag luam. Tsis tas li ntawd, nws ua hauj lwm raws li ib tug coolant nyob rau hauv daim ntawv ntawm cov kua hydrogen. Hauv kev tsim khoom semiconductor, hydrogen yog siv los ua cov roj sib npaug, etching gas, qauv roj, xoom-cov pa roj carbon monoxide thiab calibration gas, thiab siv rau hauv thermal oxidation, polysilicon ntau lawm, tungstenization, ion implantation, carrier gas xa thiab sintering.

1.Hydrogen yog heev flammable thiab tawg. Cov cuab yeej tiv thaiv dej yuav tsum tau muab tso rau hauv txhua qhov chaw siv.
2. Cov neeg ua haujlwm yuav tsum hnav tag nrho -cov khoom tiv thaiv- zoo li qub tiv thaiv suits.
3.Qhov chaw siv yuav tsum khaws cia kom deb ntawm qhov qhib nplaim taws, thiab txwv tsis pub pom lub hnub ci ncaj qha.
4.Steel cylinders yuav tsum tau muab tso rau hauv qhov chaw nyab xeeb thiab ruaj khov. Kev cuam tshuam thiab kev sib tsoo raug txwv nruj heev.
5.Siv lub laub rau luv - nrug deb. Kev tuav nqa los yog lub tog raj kheej dov yog nruj me ntsis txwv tsis pub.
6.Ua tsis tu ncua kev tshuaj xyuas ntawm lub tog raj kheej. Txhua lub tog raj kheej tsis tsim nyog raug txwv los ntawm kev pabcuam ntxiv.
