I-ejenti esebenzayo yerabha eyaziwa nangokuthi i-vulcanizing ejenti esebenzayo. I-inorganic noma i-organic substance esetshenziselwa ukwenza isisheshisi se-vulcanization sisebenze. Ingakhuphula umthamo we-accelerator, yehlise inani lesisheshisi, futhi inciphise isikhathi se-vulcanization. Iningi lezithasiselo ze-inorganic ziyi-metal oxides, i-hydroxides kanye ne-basic carbonates, njenge-zinc oxide, i-lead oxide, i-calcium hydroxide, i-lead carbonate, njll., into ebaluleke kakhulu ezithasiselweni eziphilayo ama-fatty acids, alandelwa ama-amine, insipho, njll. Njenge-stearic acid, i-dibutyloleic acid amine, njll. Isisindo esincane se-rubber, njll.

Izengezo Zenjoloba: Izakhiwo ezinemininingwane, izinzuzo, kanye nezicelo

1. I-Zinc oxide (ZnO)

Izakhiwo:

• Impushana emhlophe, engenaphunga enamandla adonsela phansi athile aphezulu (5.6 g/cm³).

• Iphuzu elincibilikayo: 1,975°C; inkomba ye-refractive: 2.008–2.029.

• Ukuphinda kusebenze okuphezulu njenge-activator ye-vulcanization.

• Izakhiwo ze-UV-blocking kanye ne-antimicrobial.

Izinzuzo:

• Isheshisa i-sulfur vulcanization (yehlisa isikhathi sokuphulukisa ngo-20-30%).

• Ithuthukisa izakhiwo zemishini (amandla aqinile + 15-25%, ubude ngesikhathi sekhefu + 10-15%).

• I-FDA-igunyazwe izicelo zokuxhumana nokudla (21 CFR 172.480).

• Ivumelana nemvelo (ayinobuthi, iyagaywa kabusha).

Izicelo:

• Amathayi: Izidumbu zamasondo ensimbi enamabhande ensimbi (ithuthukisa ukunamathela phakathi kwerabha nensimbi).

• Izicathulo: I-Outsole compounds (ithuthukisa ukumelana ne-abrasion, i-ASTM D5963: 50-80 mm³ ukulahlekelwa).

• Ezokwelapha: Amagilavu ​​okuhlinzwa (ukuvikelwa kwe-antimicrobial, ASTM E2149).

• Izinamathiselo: I-Rubber-to-metal bonding (yandisa amandla e-peel ngo-30-40%).

2. I-Phenolic Resin

Izakhiwo:

• I-polymer ye-thermosetting ene-crosslink density ephezulu.

• Ukumelana nokushisa: Ukusetshenziswa okuqhubekayo kufika ku-180°C (izikhawu ezingu-250°C).

• Ukuqina okuphezulu (i-modulus: 2–4 GPa) nokuzinza kwe-dimensional.

• Ukumelana namakhemikhali kuma-acids, izisekelo, nezinyibilikitsi.

Izinzuzo:

• Ihlinzeka ngokuqiniswa kwesakhiwo (inyusa ubulukhuni ngo-10–20 Shore A).

• I-flame retardant (isilinganiso se-UL94 V-0 ngaphandle kwezithasiselo ze-halogen).

• Ibiza kakhulu uma iqhathaniswa ne-specialty thermoplastics.

• Amasistimu okwelapha angenziwa ngokwezifiso (i-asidi-catalyzed noma isebenze ukushisa).

Izicelo:

• Amathayi: I-Sidewall compounds (ithuthukisa ukumelana nokusika, i-ASTM D624).

• Amabhande Ezimboni: Amabhande okuthutha ezindawo ezinezinga lokushisa eliphezulu (isb., izitshalo zikasimende).

• Izinto Zokushayisana: Amabhuleki amabhuleki (igcina i-coefficient of friction ku-0.35–0.45 ngaphansi kuka-200°C).

• I-Foundry: Izibophezelo zesihlabathi eziyinhloko (yehlisa ukuvela kwegesi ngesikhathi sokusakaza).
