I-Rubber esebenzayo i-ejenti eyaziwa nangokuthi i-Vulcanizing agent esebenzayo. Into engaphakathi noma ye-organic esetshenziselwa ukwenza i-accelerator ye-vulcanization isebenze. Ingakhulisa umthamo we-accelerator, yehlise inani le-accelerator, futhi linciphise isikhathi sokuvuselela. Iningi lezengezo ze-inorganic liyi-oxides yensimbi, ama-hydroxides kanye ne-carbonates eyisisekelo, njenge-zinc onide, i-calcium hydroxive, i-calbonate aphine, i-njr, i-antine ejwayelekile, i-zinc stearate, njll. I-General DOSAGE ingaphansi kwe-5% yesisindo werabha.

Izithasiselo zeRubber: Izakhiwo ezinemininingwane, izinzuzo, kanye nezinhlelo zokusebenza

1. UZinc oxide (zno)

Izakhiwo:

• I-White, i-Powder enephunga elinamakhaza aphezulu adonsela phansi (5.6 g / cm³).

• Iphuzu elincibilikayo: 1,975 ° C; I-Index Resuactive: 2.008-2.029.

• Ukuvuselelwa okuphezulu njengesishoseli se-vulcanization.

• Ukuvinjwa kwe-UV kanye nezakhiwo ze-antimicrobial.

Izinzuzo:

• Isheshisa i-Sulfur Vulcanization (inciphisa isikhathi sokuvuka ngo-20-30%).

• Kuthuthukisa izakhiwo zemishini (amandla ashubile + 15-25%, ukusunduza ekhefu + 10-15%).

• I-FDA-ivunyelwe izinhlelo zokusebenza zokuxhumana nokudla (21 CFR 172.480).

• Imvelo inobungane (okungelona ubuthi, iphinde isebenze kabusha).

Izicelo:

• Amathayi: Izidumbu ze-radio ezinsimbi ezingenantambo zensimbi (zithuthukisa ukunamathela phakathi kwenjoloba nensimbi).

• Izicathulo zezinyawo: Amakhompiyutha okuphuma (athuthukisa ukumelana ne-abrasion, i-ASTM D5963: 50-80 MM³ ukulahleka).

• Medical: Gloves ehlinchlizeni (Ukuvikelwa kwe-antimicrobial, ASTM E2149).

• Adhesives: Bonding enjoloba (kukhulisa amandla we-peel ngo-30- 40%).

2. Phenolic resin

Izakhiwo:

• I-Thermosetting polymer enobunzima obuphezulu be-crosslink.

• Ukumelana nokushisa: Sebenzisa okuqhubekayo kuze kufike ku-180 ° C (Intermittent 250 ° C).

• Ubulukhuni obuphakeme (modulus: 2-4 GPA) nokuqina okuyisici.

• Ukumelana kwamakhemikhali kuma-acid, izisekelo kanye nama-solvents.

Izinzuzo:

• Inikeza ukuqiniswa kwesakhiwo (kwandisa ubunzima ngo-10-20 Shore a).

• I-Flame Retardant (UL94 V-0 Isilinganiso ngaphandle kwe-Halogen AddItives).

• Kubiza kakhulu uma kuqhathaniswa nama-thermoplastics akhethekile.

• Izinhlelo ezenziwe ngokwezifiso zokwelapha (i-acid-catalyzed noma isebenze ukushisa).

Izicelo:

• Amathayi: Ama-Sidewall Compounds (athuthukisa ukumelana, i-ASTM D624).

• Amabhande ezimboni: Amabhande ahambisa izimboni zezindawo eziphakeme zokushisa (isib. Izitshalo zikasimende).

• Izinto zokungqubuzana: ama-brake pads (agcina i-coefficing yokushayela ku-0.35-0.45 ngaphansi kwama-200 ° C).

• I-Fedry: Ama-Binders Sand Core (anciphisa ukuziphendukela kwemvelo kwegesi ngesikhathi sokuphosa).
