1.Urwego rwo gusaba
(1). Gukoreshwa kuri reberi idahagije: nka NR, BR, NBR, IR, SBR, nibindi
(2). Koresha kuri reberi yuzuye: nka EPM irashobora guterwa gusa na peroxide, EPDM irashobora guterwa na peroxide na sulferi.
(3). Byakoreshejwe kumurongo utandukanye wa rubber: nka Q volcanisation.
2. Ibiranga sisitemu ya peroxide
(1). Imiterere y'urusobekerane rwa reberi yibirunga ni CC ihuza, ifite ingufu nyinshi, imiti ihamye, hamwe no kurwanya gusaza ubushyuhe na ogisijeni.
(2). Vulcanized reberi ifite deformasiyo ihoraho, elastique nziza kandi idakora neza.
(3). Umutekano muke wo gutunganya na peroxide ihenze.
(4). Mu gufunga neza cyangwa ubushyuhe bwo hejuru ibicuruzwa bifunga ibicuruzwa bifite intera nini yo gusaba.
3．Bisanzwe bikoreshwa peroxide
Ubusanzwe ikoreshwa rya peroxide vulcanizing ni alkyl peroxide, diacyl peroxide (dibenzoyl peroxide (BPO)) na estoxy ya peroxy. Muri byo, dialkyl peroxide ikoreshwa cyane. Nka: diisopropyl peroxide (DCP): kuri ubu niyo ikoreshwa cyane mubirunga.
2,5-dimethyl-2,5- (di-tert-butylperoxy) hexane: izwi kandi nka bis-dipentyl
4. Uburyo bwa Peroxide bwangiza
Itsinda rya peroxide ya peroxide yangirika byoroshye nubushyuhe kugirango habeho radicals yubusa, ibyo bigatuma ubwoko bwa radical yubusa bwambukiranya imiyoboro ya rubber.
5. Ingingo z'ingenzi zo guterwa na peroxide:
(1). Igipimo: kiratandukanye nubwoko butandukanye bwa reberi
Gukora neza guhuza peroxide: molekile ya 1g ya peroxide kama irashobora gukora garama zingahe za molekile ya reberi itanga imiti ihuza imiti.Niba molekile 1 ya peroxide ishobora gukora molekile 1g ya reberi ihuza, gukora neza ni 1.
Kurugero: guhuza ibikorwa bya SBR ni 12.5; guhuza ibikorwa bya BR ni 10.5; guhuza ibikorwa bya EPDM, NBR, NR ni 1; guhuza ibikorwa bya IIR ni 0.
(2). Gukoresha agent ikora hamwe na sulfurizing agent kugirango utezimbere guhuza neza
Uruhare rwa ZnO nugutezimbere ubushyuhe bwumuti, ntabwo ukora. Uruhare rwa acide stearic nugutezimbere no gukwirakwiza ZnO muri rubber. HVA-2 (N, N'-phthalimido-dimaleimide) nayo ikora neza ya peroxide.
Ongeraho ibikoresho bifasha volcanizing: cyane cyane umuhondo wa sulfure, nibindi bikoresho bifasha guhuza nka divinylbenzene, trialkyltricyanate, karubasi yuzuye, nibindi.
(3). Ongeramo umubare muto wibintu bya alkaline, nka MgO, triethanolamine, nibindi, kugirango unoze imikorere yo guhuza, wirinde gukoresha karubone yumukara na silika nibindi byuzuza aside (acide kugirango radicals yubusa passivation); antioxydants muri rusange ni amine na antioxydants ya fenolike, nayo yoroshye gukora radicals yubusa passivation, kugabanya imikorere yo guhuza, igomba gukoreshwa gake.
(4). Ubushyuhe bwa Vulcanisation: bugomba kuba hejuru yubushyuhe bwa peroxide
(5). Igihe cya Vulcanisation: muri rusange inshuro 6 ~ 10 zubuzima bwa peroxide.
Igice cya kabiri cya Peroxide: ku bushyuhe runaka, kwangirika kwa peroxide kugeza kuri kimwe cya kabiri cyumwimerere wigihe cyateganijwe, cyerekanwe muri t1 / 2.
Niba kimwe cya kabiri cyubuzima bwa DCP kuri 170 ℃ ari 1min, noneho igihe cyiza cya sulfatiyo igomba kuba 6 ~ 10min.
Urugero rwo gukora: EPDM 100 (ishingiro)
S 0.2 (umufasha wulcanizing agent)
SA 0.5 (ukora)
ZnO 5.0 (kunoza ubushyuhe)
HAF 50 (umukozi ushimangira)
DCP 3.0 (Thixotropic agent)
MgO 2.0 (Itezimbere guhuza ibikorwa)
Gukoresha amavuta 10 (umukozi woroshye)
