Umkhiqizi Intengo Enhle I-Alpha Methyl Styrene CAS 98-83-9

Intengo Enhle Yomkhiqizi I-Alpha Methyl Styrene CAS 98-83-9 Isithombe Esivelele

incazelo emfushane:

I-2-Phenyl-1-propene, eyaziwa nangokuthi i-Alpha Methyl Styrene (efingqiwe ngokuthi i-a-MS noma i-AMS) noma i-phenylisopropene, ingumkhiqizo ophuma ekukhiqizweni kwe-phenol ne-acetone ngendlela ye-cumene, ngokuvamile umkhiqizo ophumayo we-phenol ngethani elingu-0.045t α-MS. I-Alpha Methyl Styren iwuketshezi olungenambala olunephunga elimnandi. I-molecule iqukethe indandatho ye-benzene kanye ne-alkenyl esikhundleni sendandatho ye-benzene. I-Alpha Methyl Styren ithambekele ekupholiseni uma ishiswa. I-Alpha Methyl Styren ingasetshenziswa ekukhiqizweni kwezimbozo, ama-plasticizer, kanye nesinyibilikisi ezintweni eziphilayo.

I-Alpha Methyl Styrene iwuketshezi olungenambala. Ayincibiliki emanzini futhi ayiminyene kangako kunamanzi. Iphuzu le-Flash 115°F. Ingaba nobuthi obuncane ngokuyidla, ukuyiphefumula kanye nokumunca isikhumba. Umhwamuko ungaba yisidakamizwa ngokuyiphefumula. Isetshenziswa njengesinyibilikisi kanye nokwenza amanye amakhemikhali.

Izicelo ze-AMS

I-Alpha Methyl Styrene ingasetshenziswa njenge-monomer yama-polymer njengerabha ye-toluene-butadiene kanye namapulasitiki okushisa okuphezulu. Ingasetshenziswa futhi ukulungisa izembozo, izinamathiseli ezishisayo ezincibilikayo, ama-plasticizer kanye ne-musk yokwenziwa. EJapane, ama-90% e-α-methylstyrene asetshenziswa njenge-modifier ye-resin ye-ABS, kanti okunye kusetshenziswa njenge-solvent kanye nezinto zokusetshenziswa zokwenziwa kwezinto eziphilayo.

1. Okuphakathi kwepulasitiki ye-ABS, irabha ye-Styrene - Butadiene, i-Polystyrene, i-Styrene - Acrylonitrile Resins, i-Perfumery, i-Polyalphamethyl Styrene, ama-Polyer resins.
2. I-polymerization monomer, ikakhulukazi yama-polyester.
3.α-I-Methylstyrene akuyona i-monomer ye-styrenic ngomqondo oqinile. Ukufakwa esikhundleni kwe-methyl ku-side chain, kunokuba kube yindandatho enuka kamnandi, kunciphisa ukusabela kwayo ekupholiseni. Isetshenziswa njenge-monomer ekhethekile kuma-resin e-ABS, ezimbozweni, kuma-resin e-polyester, kanye nasezintweni ezinamathelayo ezincibilikisayo. Njenge-copolymer ku-ABS kanye ne-polystyrene, kwandisa ukumelana nokushisa komkhiqizo. Ezimbozweni nasema-resin, kunciphisa amazinga okusabela futhi kuthuthukisa ukucaca.
