Zolemba zina zapaketi zitha kuperekedwa malinga ndi zomwe makasitomala amafuna

Acetylene 99.9% chiyero C2H2 Gasi Industrial

Acetylene imapangidwa mwamalonda ndi zomwe zimachitika pakati pa calcium carbide ndi madzi, ndipo ndizomwe zimapangidwa ndi ethylene.

Acetylene ndi gasi wofunikira wachitsulo, amatha kuchitapo kanthu ndi okosijeni kuti apange lawi lotentha kwambiri, lomwe limagwiritsidwa ntchito popanga makina, zowotcherera, kuwotcherera ndi kudula. Kuwotcherera kwa Acetylene ndi njira yodziwika bwino yomwe imatha kumata zitsulo ziwiri kapena zingapo pamodzi kuti zikwaniritse cholinga cholumikizana molimba. Kuphatikiza apo, acetylene angagwiritsidwenso ntchito kudula zitsulo zosiyanasiyana, kuphatikizapo zitsulo zosapanga dzimbiri, zitsulo ndi aluminiyamu. Acetylene ingagwiritsidwe ntchito kupanga mankhwala monga acetylol alcohols, styrene, esters ndi propylene. Pakati pawo, acetynol ndizomwe zimagwiritsidwa ntchito nthawi zambiri organic synthesis intermediate, zomwe zingagwiritsidwe ntchito popanga mankhwala monga acetynoic acid ndi mowa ester. Styrene ndi organic pawiri ntchito kwambiri mapulasitiki, mphira, utoto ndi kupanga resins. Acetylene angagwiritsidwe ntchito m'munda wachipatala pazithandizo monga anesthesia ndi oxygen therapy. Kuwotcherera kwa Oxyacetylene, komwe kumagwiritsidwa ntchito popanga opaleshoni, ndi njira yapamwamba yodulira minofu yofewa ndikuchotsa ziwalo. Kuphatikiza apo, acetylene imagwiritsidwa ntchito popanga zida zamankhwala monga ma scalpels, nyali zosiyanasiyana zamankhwala ndi ma dilator. Kuphatikiza pa minda yomwe tatchulayi, acetylene ingagwiritsidwenso ntchito kupanga zinthu zosiyanasiyana monga mphira, makatoni ndi mapepala. Kuphatikiza apo, acetylene ingagwiritsidwenso ntchito ngati chakudya chopangira olefin ndi zida zapadera za kaboni, komanso mpweya womwe umagwiritsidwa ntchito popanga zinthu monga kuunikira, chithandizo cha kutentha ndi kuyeretsa.

Malangizo a Chitetezo

Chidule Chadzidzidzi: Gasi woyaka kwambiri.
GHS Hazard Class: Malinga ndi Chemical Classification, Chenjezo Label ndi Warning Specification mndandanda miyezo, mankhwala ndi mpweya woyaka, Kalasi 1; Mipweya yopanikizidwa, gulu: Mipweya yopanikizika - mipweya yosungunuka.
Mawu ochenjeza: Zowopsa
Zowopsa: mpweya woyaka kwambiri, wokhala ndi mpweya wothamanga kwambiri, ukhoza kuphulika pakatentha. 

Kusamalitsa:
Njira zodzitetezera: Pewani kutentha, moto, moto wotseguka, malo otentha, komanso osasuta fodya.
Yankho mwangozi: Ngati mpweya womwe ukutulukawo wagwira moto, musauzimitse motowo pokhapokha ngati gwero lomwe likutuluka lingathe kudulidwa bwinobwino. Ngati palibe chowopsa, chotsani all poyatsira magwero.
Kusunga bwino: Peŵani kuwala kwa dzuwa ndipo sungani pamalo opanda mpweya wabwino.
Kutaya: Chogulitsachi kapena chidebe chake chidzatayidwa motsatira malamulo akumaloko.
Kuopsa kwathupi ndi mankhwala: mpweya woyaka kwambiri. Acetylene imapanga zosakaniza zophulika ndi mpweya, mpweya ndi nthunzi zina zotulutsa okosijeni. Kuwola kumachitika pamene kutentha kapena kupanikizika kukwera, ndi chiopsezo cha moto kapena kuphulika. Kulumikizana ndi oxidizing wothandizira kungayambitse chiwawa. Kulumikizana ndi fluorinated chlorine kungayambitse chiwawa cha mankhwala. Itha kupanga zinthu zophulika ndi mkuwa, siliva, mercury ndi mankhwala ena. Gasi woponderezedwa, masilinda kapena zotengera zimatha kupanikizika kwambiri zikamatenthedwa ndi moto wotseguka, ndipo zimatha kuphulika. Ngozi zaumoyo: Low ndende ali ndi mankhwala ochititsa zotsatira, inhalation mutu, chizungulire, nseru, ataxia ndi zizindikiro zina. Kuchuluka kwambiri kumayambitsa asphyxia.
Zowopsa zachilengedwe: Palibe deta yomwe ilipo.
