1.Application Scope
(1). Zvinoshandiswa kusasimbiswa rarber: yakadai seNR, br, nbr, ir, sbr, etc.
(2). Nyorera kuti ugare pasi rabha: yakadai seEpm inogona kungove ichingopererwa nePeroxide, EPDM inogona kuverengerwa neese peroxide nesarufa.
(3). Inoiswa kune miscellaneous ketjar rubber: yakadai se q vanolcanization.
2. Hunhu hwePeroxide Vulcanization system
(1). Iyo network network yeiyo Vulcanized Rubber ndeyeCC Bond, ine Balish Bond Servers, Yakanyanya Chemical Stability, uye Kupokana Kunakisa kuHermal uye Opynance Kukwegura uye Oxygen AKUKURA.
(2). Vulcanized Rubber ine yakaderera zvachose kurongeka, yakanaka elasticity uye maitiro asina kunaka ekuita.
(3). Kusarongeka kwekugadzirisa kuchengeteka uye kudhura kweperoxide.
(4). Mukuisa chisimbiso kana yakakwira tembiricha yekuisa kugadzirwa zvigadzirwa zvine huwandu hwakawanda hwekushandisa.
3..awmisly anoshandisa peroxides
Kazhinji inowanzoshandiswa peroxide vulcanizizizing vamiririri velkyl peroxides, Diacyl peroxides (Dibenzoyl peeroxide (bpo)) uye peroxy esters. Pakati pavo, dialkyl peroxides anoshandiswa zvakanyanya. Se: diisopropyl peeroxide (DCp): Parizvino inonyanya kushandiswa mumiririri anovesa.
2,5-dimethyl-2,5- (di-terter-butylpereroxy) hexane: inozivikanwa zvakare seBis-dipentyl
4. Peroxide muulcanization mechanism
Boka rePeroxide rePeroxide rinoongororwa nyore nyore nekupisa remahara radicals, iro rinokonzeresa radical mhando yekuyambuka-yekubatanidza maitiro emulecular.
5. ZVINOKOSHA ZVINOKOSHA zvePeroxide Vulcanization:
(1). Dosage: inosiyana nemarudzi akasiyana marabha
Cross-inobatanidza Kubudirira kwePeroxide: 1G Molecule Peroxide inogona kuita kuti mangani magiramu emamolecules
Semuenzaniso: Kubiridzira-kunobatanidza kugona kweSBR ndeye gumi nemaviri; Iyo yekuyambuka-inobatanidza kugona kweBR ndeye 10.5; Iyo yekuyambuka-inobatanidza kugona kweEpdm, NBR, Nr ndeye 1; Iyo yekuchinjika-inobatanidza kushanda kweIiri ndeye 0.
(2). Kushandisa kweiyo inoshanda mumiririri uye co-sulfutizing mumiririri kuti uvandudze kugona kwemuchinjiko
Basa reZno ndeye kuvandudza kupisa kwekushambadzira kwekunamatira, kwete mutongi. Basa rekutsiva acid ndeyekuvandudza iyo solubility uye kupararira kwe zno mumubha. HVA-2 (n, n'-n'-phthalimido-dimaleimide) iri zvakare inoshanda activator ye peroxide.
Kuwedzera Auxialary Vulcanizization Agent: Kunyanya Sulfaur yero, uye zvimwe zvinobudirira auctifari-inobatanidza-inobatanidza-inobatanidza-inobatanidza extrever yakadaro
(3). Wedzera mashoma mashoma ezvimwe zvinhu zveAlkaline, akadai se MGE, Triethanolaulanol, etc., funga nezvekubatanidza kabhoni uye dzimwe silika Antioxidants enderera kazhinji uye phenolic antioxidants, zvakare nyore kuita mahara radicals kupaza, kuderedza kushanda kwekubatana-kwekubatanidza, kunofanirwa kushandiswa zvishoma.
(4). Tembiricha yekusagadzikana: inofanira kunge yakakwirira kupfuura tembiricha yechidhori ye peroxide
(5). Vulcanization Nguva: Kazhinji 6 ~ kagumi yenguva dzehafu-hupenyu hwenhema.
Peroxide Hafu-Hupenyu: Pane imwe tembiricha, iyo peroxide kuora kusvika hafu yekunyararira kwepakutanga yenguva inodiwa, inoratidzwa muT1 / 2.
Kana hafu-hupenyu hweDCP pa190
Fomu Muenzaniso: EPDM 100 (Base)
S 0.2 (Auxillary Vulcangizing Mumiririri)
SA 0.5 (Activator)
Zno 5.0 (kuvandudza kupisa kupesana)
Haf 50 (kusimbisa mumiririri)
DCP 3.0 (the Thisxotropic Agent)
MGO 2.0 (inovandudza kuyambuka-kubatanidza kugona)
Inoshanda mafuta gumi (nyorovesa mumiririri)
