Ethylene (C2H4)

Magawo aukadaulo

Munthawi yachibadwa, ethylene ndi mpweya wopanda mtundu, woyaka pang'ono wokhala ndi fungo loipa, womwe ndi wochepa pang'ono poyerekeza ndi mpweya. Susungunuka m'madzi, susungunuka kwambiri mu ethanol, ndipo umasungunuka pang'ono mu ethanol, ketones, ndi benzene. , Sungunuka mu ether, umasungunuka mosavuta mu organic solvents monga carbon tetrachloride.Ethylenendi chimodzi mwa zinthu zopangidwa ndi mankhwala zomwe zimatulutsa zinthu zambiri padziko lonse lapansi. Makampani opanga ethylene ndiye maziko a mafakitale opanga petrochemical. Zinthu zopangidwa ndi ethylene zimakhala ndi zinthu zoposa 75% za petrochemical ndipo zimakhala ndi udindo wofunikira pachuma cha dziko. Dziko lapansi laona kupanga ethylene ngati chimodzi mwa zizindikiro zofunika kwambiri poyesa kukula kwa mafakitale opanga petrochemical mdziko muno. Ethylene ndi chinthu chofunikira kwambiri chachilengedwe, chomwe chimagwiritsidwa ntchito kwambiri popanga polyethylene, rabara ya ethylene propylene, polyvinyl chloride, ndi zina zotero. Ethylene ndi chimodzi mwa zinthu zofunika kwambiri pamakampani opanga petrochemical. Ponena za zinthu zopangidwa, imagwiritsidwa ntchito kwambiri popanga polyethylene, vinyl chloride, ndi zina zotero; pankhani ya kapangidwe ka organic, imagwiritsidwa ntchito kwambiri popanga ethanol, ethylene oxide, ethylene glycol, acetaldehyde, ndi propylene. Zinthu zosiyanasiyana zopangira organic monga aldehydes ndi zotumphukira zake; Kupyolera mu halogenation, imatha kupanga chloroethylene, chloroethane, bromoethane, ndi zina zotero. Ethylene imagwiritsidwanso ntchito makamaka ngati mpweya wamba wa zida zowunikira m'mabizinesi a petrochemical; imagwiritsidwa ntchito ngati mpweya wokhwima wosamalira chilengedwe wa zipatso monga malalanje a navel, tangerines, nthochi, ndi zina zotero; imagwiritsidwa ntchito popanga mankhwala ndi zipangizo zamakono; imagwiritsidwa ntchito popanga magalasi apadera amakampani opanga magalimoto; imagwiritsidwa ntchito ngati firiji, makamaka m'mafakitale a LNG liquefaction. Malangizo osungira: Sungani m'nyumba yosungiramo zinthu yozizira, yopuma mpweya. Sungani kutali ndi moto ndi magwero otentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa padera ndi ma oxidants ndi halogens, ndipo pewani kusungira kosakanikirana. Gwiritsani ntchito magetsi osaphulika komanso malo opumira mpweya. N'koletsedwa kugwiritsa ntchito zida zamakanika ndi zida zomwe zimatha kuphulika. Malo osungiramo zinthu ayenera kukhala ndi zida zochizira mwadzidzidzi.

Ntchito:

①Makemikolo:

Pakati pa makampani opanga mankhwala ndi kupanga mapulasitiki

②Chakumwa Cha Chakudya:

Kucha kwa zipatso, makamaka nthochi..

③Galasi:

Magalasi apadera a makampani opanga magalimoto (galasi la magalimoto).

④ Kupanga:

Kudula zitsulo, kuwotcherera ndi kupopera kutentha mwachangu kwambiri.

⑤Firiji:

Choziziritsira makamaka m'mafakitale oyeretsera madzi a LNG.

⑥Pulasitiki ya Rabara:

Amagwiritsidwa ntchito pochotsa rabala.

Phukusi lachizolowezi:

Ubwino:

①Kuyera kwambiri, malo atsopano;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④ Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑤Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;
