Lwm qhov tshwj xeeb ntawm kev ntim khoom tuaj yeem muab tau raws li cov neeg siv khoom xav tau

Acetylene 99.9% purity C2H2 Gas Industrial

Acetylene yog tsim nyob rau hauv kev lag luam los ntawm cov tshuaj tiv thaiv ntawm calcium carbide thiab dej, thiab yog ib tug by-product ntawm ethylene ntau lawm.

Acetylene yog ib qho tseem ceeb ntawm cov hlau ua haujlwm roj, nws tuaj yeem hnov mob nrog oxygen los tsim cov nplaim hluav taws kub, siv rau hauv machining, fitters, vuam thiab txiav. Acetylene welding yog ib txoj hauv kev ua haujlwm uas tuaj yeem muab ob lossis ntau qhov hlau ua ke kom ua tiav lub hom phiaj ntawm kev sib txuas nruj. Tsis tas li ntawd, acetylene kuj tseem siv tau los txiav ntau yam hlau, nrog rau cov hlau tsis muaj steel, hlau thiab txhuas. Acetylene tuaj yeem siv los tsim cov tshuaj xws li acetylol alcohols, styrene, esters thiab propylene. Ntawm lawv, acetynol yog feem ntau siv cov organic synthesis nruab nrab, uas tuaj yeem siv los tsim cov tshuaj xws li acetynoic acid thiab cawv ester. Styrene yog ib qho organic compound dav siv hauv plastics, roj hmab, dyes thiab hluavtaws resins. Acetylene tuaj yeem siv rau hauv kev kho mob rau kev kho mob xws li tshuaj loog thiab kho cov pa oxygen. Oxyacetylene welding, siv hauv kev phais, yog cov txheej txheem siab heev rau kev txiav cov nqaij mos thiab tshem tawm lub cev. Tsis tas li ntawd, acetylene yog siv los tsim cov khoom siv kho mob xws li scalpels, ntau yam kev kho mob teeb thiab dilators. Ntxiv rau cov teb uas tau hais los saum toj no, acetylene kuj tseem siv tau los ua ntau yam ntaub ntawv xws li roj hmab, cardboard thiab ntawv. Tsis tas li ntawd, acetylene kuj tseem siv tau los ua cov khoom noj rau kev tsim cov olefin thiab cov khoom siv carbon tshwj xeeb, nrog rau cov roj siv hauv cov txheej txheem tsim khoom xws li teeb pom kev zoo, kho cua sov thiab tu.

Cov lus qhia kev nyab xeeb

Txheej txheem cej luam xwm ceev: Cov pa roj ntau heev.
GHS Hazard Class: Raws li Kev Ntsuas Tshuaj, Daim Ntawv Ceeb Toom thiab Kev Ceeb Toom Cov Qauv Txheej Txheem, cov khoom lag luam yog cov roj hluav taws xob, Chav Kawm 1; Gases nyob rau hauv siab, qeb: Pressurized gases - yaj gases.
Lus ceeb toom: Danger
Cov ntaub ntawv txaus ntshai: cov pa hluav taws kub heev, muaj cov pa roj siab siab, tuaj yeem tawg thaum tshav kub.

Cov kev ceev faj:
Kev tiv thaiv kev tiv thaiv: Khaws kom deb ntawm qhov chaw tshav kub, qhov hluav taws xob, qhib nplaim taws, qhov chaw kub, thiab tsis txhob haus luam yeeb hauv chaw ua haujlwm.
Cov lus teb raug xwm txheej: Yog tias cov pa xau hluav taws kub hnyiab, tsis txhob tua hluav taws tshwj tsis yog tias lub qhov hluav taws xob tuaj yeem raug txiav tawm kom nyab xeeb. Yog tsis muaj kev phom sij, tshem tawm ayuav ignition qhov chaw.
Kev ruaj ntseg cia: Tsis txhob tshav ntuj thiab cia rau hauv qhov chaw muaj cua zoo.
Kev pov tseg: Cov khoom no lossis nws lub thawv yuav tsum muab pov tseg raws li cov cai hauv zos.
Lub cev thiab tshuaj lom neeg muaj kev phom sij: roj nyob rau hauv lub siab kub heev. Acetylene tsim cov khoom tawg nrog cua, oxygen thiab lwm yam oxidizing vapors. Decomposition tshwm sim thaum rhuab los yog siab nce, muaj kev pheej hmoo ntawm hluav taws kub los yog tawg. Kev sib cuag nrog tus neeg sawv cev oxidizing tuaj yeem ua rau muaj kev kub ntxhov. Kev sib cuag nrog cov tshuaj fluorinated chlorine tuaj yeem ua rau muaj tshuaj lom neeg. Nws tuaj yeem tsim cov khoom tawg nrog tooj liab, nyiaj, mercury thiab lwm yam sib xyaw. Cov pa roj compressed, lub tog raj kheej lossis cov thawv ntim tau yooj yim rau overpressure thaum raug kub kub los ntawm qhov qhib hluav taws, thiab muaj kev pheej hmoo ntawm kev tawg. Kev phom sij rau kev noj qab haus huv: Tsawg concentration muaj cov tshuaj loog, ua pa ntawm mob taub hau, kiv taub hau, xeev siab, ataxia thiab lwm yam tsos mob. High concentrations ua rau asphyxia.
