1.Ububanzi besicelo

   (1). Kufakwe kurabha engagcwalisiwe: njenge-NR, BR, NBR, IR, SBR, njll.

   (2). Faka isicelo kunjoloba egcwele: njenge-EPM ingavuzwa kuphela nge-peroxide, i-EPDM ingavuzwa yiwo kokubili i-peroxide nesibabule.

   (3). Kusetshenziswa ku-miscellaneous chain rubber: njenge-Q vulcanization.

2. Izici zohlelo lwe-peroxide vulcanization

(1). Isakhiwo senethiwekhi yenjoloba ehlaselwe yi-CC bond, enamandla amakhulu ebhondi, ukuqina kwamakhemikhali aphezulu, kanye nokumelana okuhle kakhulu nokuguga okushisayo nomoya-mpilo.

(2). Irabha ene-vulcanized ine-deformation ephansi engapheli, ukunwebeka okuhle nokusebenza okungenamandla okuguquguqukayo.

(3). Ukuphepha kokucubungula okungalungile kanye ne-peroxide ebizayo.

(4). Ekubekweni uphawu okumile noma izinga eliphezulu lokushisa okumile imikhiqizo yokubeka uphawu inezinhlobonhlobo zezinhlelo zokusebenza.

3. Ama-peroxide asetshenziswa kakhulu

Ama-ejenti avame ukusetshenziswa e-peroxide ama-alkyl peroxides, ama-diacyl peroxides (i-dibenzoyl peroxide (BPO)) kanye ne-peroxy esters. Phakathi kwazo, i-dialkyl peroxides isetshenziswa kabanzi. Okufana nokuthi: i-disopropyl peroxide (DCP): okwamanje iyona esetshenziswa kakhulu i-ejenti evuvukalayo.

I-2,5-dimethyl-2,5-(di-tert-butylperoxy) i-hexane: eyaziwa nangokuthi yi-bis-dipentyl

4. I-Peroxide vulcanization mechanism

Iqembu le-peroxide le-peroxide liboliswa kalula ukushisa ukuze kukhiqizwe ama-radicals mahhala, aqala ukusabela okuxhumanisa kwe-radical yamahhala kweketango lamangqamuzana erabha.

5. Amaphuzu abalulekile e-peroxide vulcanization:

(1). Isikali: siyahlukahluka ngezinhlobo zenjoloba ezihlukene

Ukusebenza kahle kokuxhumanisa i-peroxide: I-molecule engu-1g ye-organic peroxide ingenza ukuthi mangaki amagremu ama-molecule enjoloba akhiqiza ikhemikhali yokuxhumanisa.

Isibonelo: ukusebenza kahle kokuxhumanisa kwe-SBR ngu-12.5; ukusebenza kahle kokuxhumanisa kwe-BR ngu-10.5; ukusebenza kahle kokuxhumanisa kwe-EPDM, NBR, NR ngu-1; ukusebenza kahle kokuxhumanisa kwe-IIR ngu-0.

(2). Ukusetshenziswa kwe-ejenti esebenzayo kanye ne-co-sulfurizing ejenti ukuthuthukisa ukusebenza kahle kokuxhumanisa

Indima ye-ZnO ukuthuthukisa ukumelana nokushisa kwe-adhesive, hhayi i-activator. Indima ye-stearic acid ukuthuthukisa ukunyibilika nokuhlakazeka kwe-ZnO kunjoloba. I-HVA-2 (N,N'-phthalimido-dimaleimide) futhi iyisicupha esisebenzayo se-peroxide.

Ukwengeza i-ejenti esizayo elimazayo: ngokuyinhloko i-sulphur yellow, nezinye izisiza ezixhumanisa izinto ezifana ne-divinylbenzene, i-trickkyltricyanate, i-carboxylates engagcwalisiwe, njll.

(3). Engeza inani elincane lezinto ze-alkaline, njenge-MgO, i-triethanolamine, njll., ukuze uthuthukise ukusebenza kahle kokuxhumanisa, gwema ukusetshenziswa kwe-slot carbon black and silica kanye nezinye izigcwalisi ezine-asidi (i-asidi yokwenza ama-radicals mahhala passivation); Antioxidants ngokuvamile amine kanye phenolic Antioxidants, futhi kulula ukwenza free radicals passivation, ukunciphisa ukusebenza kahle kokuxhumanisa, kufanele isetshenziswe kancane.

(4). Izinga lokushisa le-Vulcanization: kufanele libe phezulu kunezinga lokushisa lokubola le-peroxide

(5). Isikhathi se-vulcanization: ngokuvamile izikhathi ezingu-6~10 zengxenye yempilo ye-peroxide.

   Ukuphila kwesigamu se-Peroxide: ekushiseni okuthile, ukubola kwe-peroxide kuya kuhhafu wesilinganiso sokuqala sesikhathi esidingekayo, esivezwe ku-t1/2.

   Uma uhhafu wempilo ye-DCP ku-170 ℃ ingu-1min, isikhathi sayo se-sulphation esihle kufanele sibe yi-6~10min.
