I-Ethylene (C2H4)

Imingcele yezobuchwepheshe

Ngaphansi kwezimo ezijwayelekile, i-ethylene iyigesi engenambala, enephunga elincane evuthayo enomthamo ongu-1.178g/L, eminyene kancane kunomoya. Cishe ayincibiliki emanzini, ayincibiliki ku-ethanol, futhi incibilika kancane ku-ethanol, ama-ketones, ne-benzene. , Incibilika ku-ether, incibilika kalula kuzincibilikisi eziphilayo njenge-carbon tetrachloride.I-Ethyleneingenye yemikhiqizo yamakhemikhali enomkhiqizo omkhulu kunayo yonke emhlabeni. Imboni ye-ethylene iwumgogodla wemboni ye-petrochemical.I-Ethyleneimikhiqizo yenza ngaphezu kwama-75% emikhiqizo ye-petrochemical futhi ithatha isikhundla esibalulekile emnothweni kazwelonke. Umhlaba ubheke ukukhiqizwa kwe-ethylene njengenye yezinkomba ezibalulekile zokulinganisa izinga lokuthuthuka kwemboni yezwe ye-petrochemical. I-Ethylene iyi-organic amakhemikhali abalulekile eyisisekelo impahla eluhlaza, ikakhulukazi esetshenziswa ekukhiqizeni i-polyethylene, irabha ye-ethylene propylene, i-polyvinyl chloride, njll. I-Ethylene ingenye yezinto eziyisisekelo ezisetshenziswa kakhulu embonini ye-petrochemical. Ngokuphathelene nezinto zokwenziwa, isetshenziswa kabanzi ekukhiqizeni i-polyethylene, i-vinyl chloride, njll.; ngokuya nge-organic synthesis, isetshenziswa kabanzi ekuhlanganiseni kwe-ethanol, i-ethylene oxide, i-ethylene glycol, i-acetaldehyde, ne-propylene. Izinhlobonhlobo zezinto zokusetshenziswa eziyisisekelo ze-organic synthesis ezifana nama-aldehyde nokuphuma kwawo; ngokusebenzisa i-halogenation, ingakhiqiza i-chlorethylene, i-chloroethane, i-bromoethane, njll. I-Ethylene nayo isetshenziswa kakhulu njengegesi ejwayelekile yezinsimbi zokuhlaziya emabhizinisini e-petrochemical; esetshenziswa njengegesi yokuvuthwa evumelana nemvelo yezithelo ezinjengamawolintshi enkaba, ama-tangerine, ubhanana, njll.; esetshenziswa ekuhlanganiseni kwemithi nezinto zobuchwepheshe obuphezulu; esetshenziswa ekukhiqizeni ingilazi ekhethekile embonini yezimoto; esetshenziswa njengesiqandisi , Ikakhulukazi ezitshalweni zoketshezi lwe-LNG. Imithetho yesitoreji: Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokuhlukana nama-oxidants nama-halogen, futhi igweme isitoreji esixubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

①Amakhemikhali:

Ophakathi embonini yamakhemikhali kanye nokukhiqizwa kwamapulasitiki

②Isiphuzo Sokudla:

Ukuvuthwa kwezithelo, ikakhulukazi ubhanana..

③Ingilazi:

Ingilazi ekhethekile yemboni yezimoto (ingilazi yemoto).

④ Ukwenziwa:

Ukusika insimbi, i-welding kanye ne-High Velocity Thermal Spraying.

⑤Isiqandisi:

Isiqandisi ikakhulukazi ezitshalweni ezikhiqiza uketshezi lwe-LNG.

⑥Ipulasitiki Yerabha:

Isetshenziswa ekukhishweni kwenjoloba.

Iphakheji evamile:

Inzuzo:

①Ukuhlanzeka okuphezulu, indawo yakamuva;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑤Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
