Ibikoresho bya reberi bizwi kandi nka volcanizing agent. Ikintu kidasanzwe cyangwa kama gikoreshwa mugukora umuvuduko wihuta. Irashobora kongera ubushobozi bwihuta, kugabanya umuvuduko wihuta, no kugabanya igihe cyibirunga. Ibyinshi mu byongeramo ingufu ni okiside yicyuma, hydroxide na karubone yibanze, nka okiside ya zinc, okiside ya okiside, calcium hydroxide, karubone ya karubone, nibindi, ikintu cyingenzi mubyongeweho kama ni aside irike, ikurikirwa na amine, amasabune, nibindi.

Ibikoresho bya reberi: Ibisobanuro birambuye, Ibyiza, na Porogaramu

1. Oxide Zinc (ZnO)

Ibyiza:

• Ifu yera, idafite impumuro ifite uburemere bwihariye (5,6 g / cm³).

• Ingingo yo gushonga: 1.975 ° C; indangantego yo kwanga: 2.008–2.029.

• Gukora cyane nkumukangurambaga wibirunga.

• UV-guhagarika hamwe na mikorobe.

Ibyiza:

• Kwihutisha ibirunga bya sulfuru (bigabanya igihe cyo gukira 20-30%).

• Itezimbere imashini (imbaraga zingana + 15-25%, kurambura kuruhuka + 10-15%).

• FDA-yemewe kubisabwa-guhuza ibiryo (21 CFR 172.480).

• Ibidukikije byangiza ibidukikije (bidafite uburozi, bisubirwamo).

Porogaramu:

• Amapine: Imirambo ya radiyo yumukandara wumurambo (byongera guhuza hagati ya reberi nicyuma).

• Inkweto: Ibikoresho byo hanze (bitezimbere abrasion, ASTM D5963: 50-80 mm³ gutakaza).

• Ubuvuzi: Gants zo kubaga (kurinda mikorobe, ASTM E2149).

• Ibifatika: Guhuza ibyuma-byuma (byongera imbaraga zishishwa 30-40%).

2. Fenolike

Ibyiza:

• Thermosetting polymer hamwe nubucucike buri hejuru.

• Kurwanya ubushyuhe: Gukomeza gukoresha kugeza kuri 180 ° C (hagati ya 250 ° C).

• Gukomera cyane (modulus: 2-4 GPa) hamwe no guhagarara neza.

• Kurwanya imiti ya acide, shingiro, hamwe na solve.

Ibyiza:

• Itanga imbaraga zubaka (byongera ubukana kuri 10-20 Inkombe A).

• Flame retardant (UL94 V-0 igipimo kitarimo inyongera ya halogene).

• Ikiguzi-cyiza ugereranije na thermoplastique yihariye.

• Sisitemu yo gukiza yihariye (acide-catisale cyangwa ubushyuhe-bukora).

Porogaramu:

• Amapine: Ibikoresho byo kuruhande (bitezimbere kugabanuka, ASTM D624).

• Imikandara yinganda: Imikandara ya convoyeur kubushyuhe bwo hejuru (urugero, ibihingwa bya sima).

• Ibikoresho byo guterana amagambo: feri yerekana feri (ikomeza coefficient de fraisation kuri 0.35–0.45 munsi ya 200 ° C).

• Urufatiro: Umuhengeri wumucanga (ugabanya ubwihindurize bwa gaze mugihe cyo guta).
