CAS No. 74-85-1 Ethylene Supplier. Makhalidwe a Ethylene
Nambala ya CAS 74-85-1 ikufanana ndi Ethylene, mpweya wopanda mtundu, woyaka moto womwe umagwira ntchito yofunika kwambiri pamakampani a petrochemical ndi biology ya zomera. Nayi mikhalidwe yayikulu ya ethylene:
Njira ya Chemical: C2H4
Thupi Lanyama: Pa kutentha ndi kupanikizika, ethylene ndi mpweya.
Kulemera kwa Maselo: Pafupifupi 28.05 g/mol.
Malo Owira: -103.7°C (-154.66°F) pa 1 atmosphere.
Malo Osungunuka: -169.2°C (-272.56°F).
Kachulukidwe: Pafupifupi 1.18 kg/m³ pa STP, yopepuka pang'ono kuposa mpweya.
Kusungunuka: Kusungunuka pang'ono m'madzi komanso kusungunuka muzosungunulira zambiri.
Kutentha ndi Kuchitanso: Zoyaka kwambiri ndipo zimatha kupanga zosakaniza zophulika ndi mpweya. Imakhudzidwa ndi ma halojeni, okosijeni, ndi ma asidi amphamvu.
Kugwiritsa ntchito Ethylene:
** Petrochemical Industry**: Ethylene ndi chomangira choyambirira popanga mankhwala ndi mapulasitiki ambiri, kuphatikiza polyethylene (pulasitiki yodziwika kwambiri padziko lonse lapansi), ethylene glycol (yomwe imagwiritsidwa ntchito mu ulusi woletsa kuzizira ndi poliyester), ndi ethylene oxide (yomwe imagwiritsidwa ntchito kupanga zotsukira ndi mapulasitiki).
Ulimi: Amagwiritsidwa ntchito ngati chopangira zipatso komanso ngati chowongolera kukula mu ulimi wamaluwa chifukwa cha ntchito yake ngati mahomoni achilengedwe achilengedwe, kulimbikitsa kucha kwa zipatso, kumera kwamaluwa, ndi kutulutsa.
Kupanga: Amagwiritsidwa ntchito popanga vinyl chloride (ya PVC), styrene (ya polystyrene), ndi mankhwala ena achilengedwe.
Zolinga Zachitetezo:
Kuopsa kwa Moto ndi Kuphulika: Kutentha kwambiri kwa ethylene kumafuna kutsata mosamalitsa njira zopewera moto ndi mpweya wabwino panthawi yogwira ndi kusunga.
Poizoni: Kuwonekera kwa nthawi yayitali kuzinthu zambiri kungayambitse chizungulire, mutu, ndi kupuma movutikira m'madera opanda mpweya.
Kuwonongeka kwa chilengedwe: Ngakhale kuti ethylene imasweka mofulumira mumlengalenga, kupanga ndi kugwiritsidwa ntchito kwake kumathandizira kutulutsa mpweya woipa wowonjezera kutentha mwa njira yogwiritsira ntchito mphamvu ndi kupanga mankhwala ogwirizana nawo.
Kochokera:
Ogulitsa ethylene nthawi zambiri amaphatikiza makampani akuluakulu a petrochemical ndi makampani ogawa gasi omwe amagwiritsa ntchito mpweya wa mafakitale. Ogulitsa awa nthawi zambiri amakhala ndi ntchito zophatikizika zomwe zimaphatikizapo kuchotsa ethylene kuchokera kumafuta osakanizika kapena mitsinje yamafuta achilengedwe, kuyeretsedwa kwake, ndikugawa kwa makasitomala kudzera pa mapaipi, matanki, kapena masilindala, kutengera kuchuluka ndi zofunikira zogwiritsa ntchito kumapeto. Mukapeza ethylene, ndikofunikira kuyanjana ndi ogulitsa odziwika bwino omwe amatsatira malamulo okhwima otetezedwa ndi chilengedwe, kuwonetsetsa kuti malondawo ndi abwino komanso momwe amagwiritsidwira ntchito moyenera.
Ngati mukufuna zinthu zotere, chonde omasuka kulankhula nafe!
