Iinkcukacha zeMveliso

Iithegi zeMveliso

Inkcazo:I-Styrene (C8H8), i-liquid ebalulekileyo ye-chemical material ekrwada, yi-monocyclic enuka kamnandi ye-hydrocarbon ene-olefin esecaleni kwekhonkco kunye ne-conjugated system eneringi ye-benzene.Lelona lungu lilula nelona libalulekileyo le-unsaturated aromatics hydrocarbons.I-Styrene isetyenziswa ngokubanzi njengento ekrwada yokuveliswa kwee-resin zokwenziwa kunye nerabha yokwenziwa.
I-Styrene lulwelo olungenambala kubushushu begumbi, olunganyibilikiyo emanzini, kodwa lunyibilika kwizinyibilikisi zendalo ezifana nepetroli, i-ethanol kunye ne-ether, kwaye inetyhefu kwaye inevumba elikhethekileyo.Ngenxa yokuba i-styrene ine-unsaturated bonds ephindwe kabini kwaye yenza i-Chemicalbook conjugated system kunye neringi ye-benzene, inomsebenzi oqinileyo wekhemikhali kwaye kulula ukuzenzela i-polymerize kunye ne-polymerize.Ngokuqhelekileyo, i-styrene ikhululekile-ipolymerized ngokufudumeza okanye i-catalyst.I-styrene iyatsha kwaye inokwenza imixube eqhumayo kunye nomoya.

Iimpawu:Ukuguquguquka okunamandla

Isicelo:

1. Isetyenziswa kakhulu njengezinto eziluhlaza kwi-polystyrene, irabha yokwenziwa, iiplastiki zobunjineli, i-ion exchange resin, njl.

2. Ukusetyenziswa okubaluleke kakhulu njenge-monomer yerabha yokwenziwa kunye neeplastiki ukuvelisa irabha ye-styrene-butadiene, i-polystyrene, kunye ne-polystyrene enegwebu;Ikwasetyenziselwa ukwenza i-copolymerize kunye nezinye ii-monomers ukwenza iiplastiki zobunjineli ngeenjongo ezahlukeneyo.

3. Kwi-organic synthesis kunye ne-resin synthesis

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

Umqulu:170kg ubunzima net, okanye imfuneko njengoMthengi.

Ezothutho kunye nokugcinwa:

1. Ngenxa yeempawu zayo zeekhemikhali ezisebenzayo, i-styrene igcinwa kwindawo epholileyo nengena umoya.

2. Gcina kude nomlilo kunye nemithombo yobushushu, kwaye iqondo lokushisa akufanele lidlule i-25 ℃

3. Ukuze kuthintelwe i-self-polymerization ye-styrene, i-TBC polymerization inhibitor idla ngokudibaniswa ngexesha lokugcinwa kunye nokuthutha.

Ngaphambili: I-Stearyl methacrylate (SMA)

Okulandelayo: I-Tert-Butyl Acrylate (TBA)
