1.Te atanga tono
(1). Ka whakamahia ki te rapa haunga: penei i te NR, BR, NBR, IR, SBR, etc.
(2). Hoatu ki te rapa kukū: penei i te EPM ka taea anake te whakapuru ma te peroxide, te EPDM ka taea te whakapuru e rua me te whanariki.
(3). Ka whakamahia ki nga momo rapa mekameka: penei i te whakaraeraetanga Q.
2. Nga ahuatanga o te punaha vulcanization peroxide
(1). Ko te hanganga whatunga o te rapa puia ko te here CC, me te kaha o te here, te pumau matū nui, me te tino pai ki te taikaha o te waiariki me te hāora.
(2). rapa puia he iti deformation pūmau, elasticity pai me te mahi hihiri rawakore.
(3). He iti te haumaru o te tukatuka me te peroxide utu nui.
(4). I roto i te taatiraa pateko tiketike pāmahana pateko taatiraa hua i te whānuitanga o ngā tono.
3．Peroxides whakamahia noa
Ko nga mea whakaraerae peroxide e whakamahia nuitia ana ko te alkyl peroxides, diacyl peroxides (dibenzoyl peroxide (BPO)) me te peroxy esters. I roto i a raatau, ka whakamahia te dialkyl peroxides. Pērā i: te diisopropyl peroxide (DCP): i tēnei wā te mea tino whakamahia hei māngai whakapuru.
2,5-dimethyl-2,5-(di-tert-butylperoxy) hexane: mohiotia ano ko bis-dipentyl
4. Hangaia te whakangao peroxide
Ko te roopu peroxide o te peroxide ka ngawari te pirau e te wera ki te whakaputa i nga rauropi kore utu, e whakaohooho ana i te tauhohenga hononga-whakawhitinga momo tuwhena kore utu o te mekameka ngota rapa.
5. Nga waahanga matua o te whakangao peroxide:
(1). Inenga: he rereke ki nga momo rapa rereke
Te pai o te honohono o te peroxide: 1g te ngota ngota o te waikura waro ka taea te hanga e hia karamu o nga ngota ngota rapa e whakaputa hononga matū.
Hei tauira: ko te 12.5 te pai o te whakawhiti hononga o te SBR; ko te pai o te whakawhiti hononga o BR ko 10.5; ko te pai o te whakawhiti hononga o EPDM, NBR, NR ko 1; Ko te pai o te hono-whakawhiti o IIR he 0.
(2). Te whakamahi i te kaihoko kaha me te kaihoko whakawhanawhara hei whakapai ake i te pai o te honohono
Ko te mahi a ZnO ko te whakapai ake i te parenga wera o te whakapiri, ehara i te kaiwhakaoho. Ko te mahi a te waikawa stearic he whakapai ake i te whakarewatanga me te marara o ZnO i roto i te rapa. Ko te HVA-2 (N,N'-phthalimido-dimaleimide) he kaiwhakaoho whai hua o te peroxide.
Ko te taapiri i te kaihoko whakaraerae awhina: ko te nuinga o te whanariki he kowhai, me etahi atu taapiri honohono penei i te divinylbenzene, trialkyltricyanate, carboxylates haunga, etc.
(3). Tāpirihia he iti o nga matū kawakore, penei i te MgO, triethanolamine, me etahi atu, hei whakapai ake i te pai o te honohono-whakawhiti, karohia te whakamahi i te waro waro pango me te silica me etahi atu whakakii waikawa (waikawa hei hanga i nga rauropi kore utu); Ko nga antioxidants te nuinga o te amine me te phenolic antioxidants, he ngawari hoki ki te hanga i nga radical free passivation, te whakaiti i te kaha o te whakawhiti-hononga, me whakamahi iti.
(4). Te pāmahana whakawetiweti: kia teitei ake i te pāmahana pirau o te peroxide
(5). Te wa whakakino: te tikanga 6~10 nga wa o te haurua-ora o te peroxide.
Te haurua-ora o te peroxide: i tetahi pāmahana, ka pakaru te peroxide ki te haurua o te kukū taketake o te wa e hiahiatia ana, ka whakaatuhia ki te t1/2.
Mena ko te haurua-ora o te DCP i te 170 ℃ he 1min, katahi ka 6 ~ 10min tona wa sulphation pai.
Tauira whakatakotoranga: EPDM 100 (turanga)
S 0.2 (mahinga whakapuru awhina)
SA 0.5 (whakahohe)
ZnO 5.0 (hei whakapai ake i te parenga wera)
HAF 50 (te kaihoko whakakaha)
DCP 3.0 (Thixotropic agent)
MgO 2.0 (Whakapai ake i te pai o te hono-whakawhitinga)
