Amapharamitha obuchwepheshe

I-1,3-Butadiene iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ye-C4H6. Iyigesi engenambala enephunga elimnandi kancane futhi kulula ukuyincibilikisa. Ayinobuthi obuncane futhi ubuthi bayo bufana nobe-ethylene, kodwa inokucasuka okukhulu esikhumbeni nakuma-mucous membranes, futhi inomphumela wokubulala izinzwa lapho igcwele kakhulu. I-1,3 I-Butadiene iyasha futhi ingakha ingxube eqhumayo uma ixutshwe nomoya; kulula ukuyishisa nokuqhuma lapho ivezwa ekushiseni, izinhlansi, amalangabi noma ama-oxidants; uma ihlangana nokushisa okuphezulu, kungenzeka ukusabela kwe-polymerization, kukhiphe ukushisa okuningi futhi kubangele ukuqhekeka kwesitsha kanye nezingozi zokuqhuma; Inzima kunomoya, ingasakazeka ibanga elide endaweni ephansi, futhi izobangela ukusha emuva lapho ihlangana nomlilo ovulekile. I-1,3 i-butadiene iyashiswa futhi iboliswe ibe yi-carbon monoxide kanye ne-carbon dioxide. Ayincibiliki emanzini, incibilika ku-ethanol kanye ne-methanol, futhi incibilika kalula ezinyibilikisini eziningi zezinto eziphilayo ezifana ne-acetone, i-ether kanye ne-chloroform. 1,3 I-Butadiene iyingozi emvelweni futhi ingabangela ukungcola emanzini, enhlabathini nasemkhathini. 1,3 I-Butadiene ingumkhiqizi oyinhloko werabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, i-neoprene) kanye nama-resin ahlukahlukene anokusetshenziswa okubanzi (njenge-ABS resin, i-SBS resin, i-BS resin, i-MBS resin) Izinto zokusetshenziswa, i-butadiene nayo inokusetshenziswa okuningi ekukhiqizweni kwamakhemikhali amahle. 1,3 i-butadiene kufanele igcinwe endaweni yokugcina epholile, enomoya ukuze kutholakale amagesi avuthayo. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokwehlukana nama-oxidants, ama-halogen, njll., futhi ugweme ukugcina okuxubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini yemishini namathuluzi avame ukuba nezinhlansi. Indawo yokugcina kufanele ifakwe imishini yokwelapha ephuthumayo evuzayo.

Isicelo:

①Ukukhiqizwa kwerabha yokwenziwa:

1,3 I-Butadiene iyinto eluhlaza eyinhloko yokukhiqizwa kwerabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, kanye ne-neoprene)

② Izinto zokusetshenziswa zamakhemikhali eziyisisekelo:

I-Butadiene ingacutshungulwa kabanzi ukuze ikhiqize i-hexamethylene diamine kanye ne-caprolactam, ibe ngenye yezinto ezibalulekile zokusetshenziswa zokulungiselela i-nylon.

③Amakhemikhali amahle:

Amakhemikhali amahle enziwe nge-butadiene njengezinto zokusetshenziswa.

Iphakheji evamile:

Manje sinabasebenzi abangochwepheshe nabasebenzayo abazoletha umhlinzeki wekhwalithi ephezulu kumakhasimende ethu. Sivame ukulandela umgomo wokugxila kumakhasimende, imininingwane egxile kumakhasimende ka-2019 Umhlinzeki wekhwalithi ephezulu waseShayina 1 3-Butadiene, CAS: 106-99-0, “Ushintsho lube lukhulu!” yisiqubulo sethu, esisho ukuthi “Umhlaba wonke omkhulu uphambi kwethu, ngakho-ke masiwuthande!” Ushintsho lube lukhulu kuwe!

I-China 1 3-Butadiene, Butadiene ka-2019 esezingeni eliphezulu, Uma kukhona umkhiqizo ohlangabezana nesidingo sakho, khumbula ukuzizwa ukhululekile ukuxhumana nathi. Siyaqiniseka ukuthi noma yimuphi umbuzo noma isidingo sakho uzothola ukunakwa okusheshayo, izixazululo ezisezingeni eliphezulu, amanani akhethekile kanye nempahla eshibhile.
