Theko e ntle ea rabara ea Styrene e Phahameng / HSR 60 / HSR 68 / HSR 80 / HSR 85
Rabara e nang le styrene e ngata ke mofuta o ikhethang oa rabara ea styrene butadiene. Ke polymer e seng polar e entsoeng ka co-polymerization ea styrene le butadiene latex. Sebopeho sa lik'hemik'hale:
—(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n—
Ke granule e tšoeu, ha e na chefo, ha e nkge ebile e ka tuka. Mocheso oa ho sotha mocheso: 70-90℃, e tšoeu e tiileng. E sebelisoa e le sesebelisoa sa ho tlatsa ho ntlafatsa ho thatafala, ho hanyetsa botsofali, ho hanyetsa ho tsofala, matla a ho taboha le matla a ho thaepa a lirabara. E na le thermoplasticity e ntle le thepa ea ho thibela mocheso ea motlakase.
Rabara e nang le styrene e phahameng e loketse tlhahiso ea lihlahisoa tse thata haholo le tse nang le boima bo tlase.
1. Ho etsa lieta: lithapo tse thata, serethe, thapo e thata ea foam, lieta tsa letlalo tse iketsang jj.;
2.Jwalo ka thepa ya mokatong: thaele ya rabara ya mokatong; dihlahiswa tsa indasteri, jwalo ka moqolo wa rabara, washer, tube ya rabara e thata le dihlahiswa tse ding tsa seponche;
3. Indasteri ea lipapali: libolo, rollerskate;
4. Thepa ea ho thibela mocheso ea motlakase;
5. Thaere ea sekoahelo sa baesekele ea boemo bo holimo; rolara e fapaneng ea pastern e hatisitsoeng; rabara ea slab;
6. ABS, AS polasetiki;
Lilemong tsa morao tjena, masimo a rabara a ela hloko haholo ho matlafatseng rabara e nang le styrene e ngata, haholo-holo indastering ea likoloi, joalo ka ha e sebelisoa thaereng. Ka hona, 'maraka o ka bang teng oa HSR o moholo haholo. HSR ea rona e ka nka sebaka sa NIPOL HS850, HS860&HS870, JSR0060 le KER1904 le HS260 ea Japane jj.
Ka mokotleng o matla o kopantsoeng o nang le mokotlana o lohiloeng o koahetsoeng ka PE/mokotlana oa pampiri ea kraft, boima ba 'nete ba 20kg. Sireletsa khahlanong le mollo, metsi le khanya ea letsatsi. E bolokiloe sebakeng se pholileng le se nang le moea o pholileng.
