Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo:I-Styrene (C8H8), ikhemikhali eliwuketshezi elibalulekile elisetshenziswayo, iyi-monocyclic enuka kamnandi ene-olefin side chain kanye nesistimu ehlanganisiwe eneringi ye-benzene.Yilungu elilula nelibaluleke kakhulu lama-hydrocarbon anephunga elimnandi.I-styrene isetshenziswa kabanzi njengento eluhlaza ekukhiqizeni ama-synthetic resins kanye nerabha yokwenziwa.
I-styrene iwuketshezi olungenambala ekamelweni lokushisa, olungancibiliki emanzini, kodwa luncibilika kuzincibilikisi zemvelo ezifana nophethiloli, i-ethanol ne-ether, futhi sinobuthi futhi sinephunga elikhethekile.Ngenxa yokuthi i-styrene inamabhondi akabili angagcwele futhi yenza isistimu ehlanganisiwe ye-Chemicalbook eneringi ye-benzene, inokuphinda isebenze kwamakhemikhali okuqinile futhi kulula ukuzenza i-polymerize futhi i-polymerize.Ngokuvamile, i-styrene i-polymerized mahhala ngokushisa noma i-catalyst.I-styrene iyavutha futhi ingenza izingxube eziqhumayo ngomoya.

Izici:Ukuguquguquka okuqinile

Isicelo:

1. Isetshenziswa kakhulu njengempahla eluhlaza ye-polystyrene, irabha yokwenziwa, amapulasitiki obunjiniyela, i-ion exchange resin, njll.

2. Ukusetshenziswa okubaluleke kakhulu kufana ne-monomer yerabha yokwenziwa namapulasitiki ukukhiqiza irabha ye-styrene-butadiene, i-polystyrene, ne-polystyrene enegwebu;iphinde isetshenziselwe ukwenza i-copolymerize namanye ama-monomers ukwenza amapulasitiki obunjiniyela ngezinhloso ezahlukahlukene.

3. Okokwenziwa kwezinto eziphilayo kanye ne-resin synthesis

4. Isetshenziselwa ukwenza i-copper plating brightener, edlala indima yokulinganisa nokukhanyisa.

Iphakheji:170kg isisindo net, noma imfuneko njengoba Customer.

Ezokuthutha nokugcina:

1. Ngenxa yezakhiwo zayo zamakhemikhali ezisebenzayo, i-styrene ngokuvamile igcinwa endaweni epholile nengena umoya.

2. Gcina kude nemithombo yomlilo neyokushisa, futhi izinga lokushisa lokugcina akufanele lidlule ku-25℃

3. Ukuze uvimbele i-self-polymerization ye-styrene, i-TBC polymerization inhibitor ivame ukungezwa ngesikhathi sokugcina nokuthutha.

Okwedlule: I-Stearyl methacrylate (SMA)

Olandelayo: I-Tert-Butyl Acrylate (TBA)
