1.Ukubhekana nobubanzi

   (1). Kusetshenziswe kurabha elingalawulwa: njenge-NR, BR, NBR, IR, SBR, njll.

   (2). Faka isicelo kurabha eligcwele: njenge-EPM kungavunywa kuphela yi-peroxide, i-EPDM ingavunywa yi-peroxide kanye nesibabule.

   (3). Isetshenziswa kurabha elixubile le-chain: njengokuvunywa kwe-Q.

2. Izici zohlelo lwe-peroxide vulcanization

(1). Ukwakheka kwenethiwekhi yeRubber eVulcanized yi-CC Bond, nge-High Bonder Energy, ukuqina okuphezulu kwamakhemikhali, nokumelana okuhle kokuguga okushisayo nomoya oxygen.

(2). I-Vutecanized Rubber inokuguquguquka okuphansi okuphansi, ukuqina okuhle nokusebenza kabi okunamandla.

(3). Ukuphepha okungekuhle kokuphepha kanye ne-peroxide ebizayo.

(4). Ngokuvalwa kwalo okuvumayo noma imikhiqizo ephezulu ye-static sealing enezicelo ezahlukahlukene zinobubanzi bezicelo.

3.COMNELY ISELULEKILE

Ama-ejenti we-peroxide polcaning asetshenziswayo asetshenziswa ama-alkyl peroxides, i-percoxides ye-diacyl (i-dibenzoyl peroxide (BPO)) kanye nama-perexy esters. Phakathi kwazo, i-Dialkyl Peroxides isetshenziswa kabanzi. Njengoku: Diisopropyl Peroxide (DCP): Okwamanje okwamanje kusetshenziswe kakhulu i-ejenti ye-Vulcaning.

2,5-DIMETYL-2,5- (DI-Tert-Butylpeoxy) Hhexane: Waziwa nangokuthi Bis-Dipnynyin

4. I-Peroxide Vulcanization Mechanism

Iqembu le-peroxide le-peroxide libolekwa kalula ngokushisa ukuze likhiqize ama-radicals wamahhala, adala ukusabela kwamahhala okuxhumeka kwe-radical ratect of chain moleklar.

5. Amaphuzu asemqoka we-peroxide Vulcanization:

(1). Umthamo: Iyahlukahluka ngezinhlobo ezihlukile zenjoloba

Ukusebenza okuxhumeka kwe-peroxide: I-1G Molecule ye-Organic Peroxide ingenza ukuthi ama-gramu amangaki ama-molekyuli enjoloba akhiqiza ukuxhumana kwamakhemikhali.Uma 1 molecule we-peroxide angenza ama-molecule we-ruble axhumene nerabha, ukusebenza kahle okuxhumeka kungu-1.

Isibonelo: ukusebenza okuxhumeka kwe-SBR kungu-12,5; Ukusebenza okuxhumeka kwesiphambano sika-BR ngu-10 10.5; Ukusebenza okuxhumeka kwesiphambano kwe-EPDM, i-NBR, i-NR ingu-1; Ukusebenza okuxhumanisayo kwe-IIR kungu-0.

(2). Ukusetshenziswa kwe-ejenti esebenzayo kanye ne-ejenti ye-sulfurizing ukuthuthukisa ukusebenza kahle okuxhumanisayo

Iqhaza le-ZNO ukuthuthukisa ukumelana nokushisa kokunamathela, hhayi i-activator. Iqhaza le-Stearic acid ukuthuthukisa i-solubity kanye nokuhlakazwa kwe-zno kurabha. I-HVA-2 (N, N'-PHTHALIMIDO-Dimalekide) futhi i-activator ephumelelayo ye-peroxide.

Ukungeza i-ejenti ye-Vuxilicleipleting ephuzi: ikakhulukazi ophuzi ophuzi, nezinye izinhlaka ezixhumanisa ama-auxiliary acking-exhumanisa anjenge-divinylbenzene, i-clingkylsticteate, i-carbox motorboxy, njll.

(3). Faka inani elincane lezinto ze-alkaline, ezinjenge-MGO, Triethanolamine, njll., Ukuthuthukisa ukusebenza kahle kokuxhuma, gwema ukusetshenziswa kwe-slot carbon emnyama ne-silica nezinye izihlubuki ze-acidic (acid ukwenza ukufudumala kwama-radicals); I-antioxidants ngokuvamile i-antioxidants ye-antionic ne-phenolic, kulula futhi ukwenza ukuphumelela kwama-radicals wamahhala, kunciphisa ukusebenza kahle kokuxhuma, kufanele kusetshenziswe kancane.

(4). Ukushisa kwe-Vulcanization: kufanele kube ngaphezulu kokushisa kokuwohloka kwe-peroxide

(5). Isikhathi se-Vulcanization: Ngokuvamile ama-6 ~ 10 izikhathi eziyi-10 ze-Half-Life of Peroxide.

   I-Peroxide Half-Life: Kumazinga okushisa athile, ukubola kwe-peroxide kube yingxenye yokuhlushwa kwasekuqaleni kwesikhathi esidingekayo, kuvezwe ku-T1 / 2.

   Uma i-Half-Life of DCP ku-170 ℃ ingu-1min, khona-ke isikhathi sayo se-aulphation esihle kufanele kube yi-6 ~ 10min.
