Rabara e sebetsang hape e tsejwang e le vulcanizing active agent. Sehlahisoa sa inorganic kapa organic se sebedisoang ho etsa hore vulcanization accelerator e sebetse. E ka eketsa bokhoni ba accelerator, ea fokotsa palo ea accelerator, 'me ea khutsufatsa nako ea vulcanization. Boholo ba li-additives tsa inorganic ke metal oxides, hydroxides le basic carbonates, tse kang zinc oxide, lead oxide, calcium hydroxide, lead carbonate, joalo-joalo, ntho ea bohlokoa ka ho fetisisa ho li-additives tsa organic ke mafura a acid, a lateloa ke amine, sesepa, joalo-joalo joalo ka stearic acid, dibutyloleic acid amine, zinc stearate, joalo-joalo.

Li-additives tsa Rubber: Thepa e qaqileng, Melemo, le Lisebelisoa

1. Zinc oxide (ZnO)

Thepa:

• Phofo e tšoeu, e sa nkheng e nang le matla a khoheli a khethehileng (5.6 g/cm³).

• Sebaka se qhibilihang: 1,975 ° C; index ea refractive: 2.008–2.029.

• Reactivity e phahameng joalo ka activator ea vulcanization.

• UV-blocking le thepa ea antimicrobial.

Melemo:

• E potlakisa sulfur vulcanization (e fokotsa nako ea ho folisa ka 20-30%).

• E ntlafatsa thepa ea mochine (matla a tensile + 15-25%, elongation nakong ea khefu + 10-15%).

• FDA-e amohetsoe bakeng sa likopo tsa ho ikopanya le lijo (21 CFR 172.480).

• E na le tikoloho (e seng chefo, e ka sebelisoa hape).

Lisebelisoa:

• Lithaere: Litopo tsa mabili a tšepe tse nang le mabanta a tšepe (e matlafatsa ho khomarela pakeng tsa rabara le tšepe).

• Lieta: Lik'hemik'hale tsa Outsole (ho ntlafatsa ho hanyetsa ha abrasion, ASTM D5963: 50-80 mm³ tahlehelo).

• Bongaka: Li-gloves tsa ho buoa (tšireletso ea likokoana-hloko, ASTM E2149).

• Likhomaretsi: Ho kopanya rabara le tšepe (e eketsa matla a peel ka 30-40%).

2. Phenolic Resin

Thepa:

• Thermosetting polymer e nang le sekhahla se phahameng sa crosslink.

• Ho hanyetsa mocheso: Tšebeliso e tsoelang pele ho fihlela ho 180 ° C (nako le nako 250 ° C).

• Boima bo phahameng (modulus: 2-4 GPa) le botsitso ba dimensional.

• Ho hanyetsa lik'hemik'hale ho li-acids, metheo, le li-solvents.

Melemo:

• E fana ka matlafatso ea sebopeho (e eketsa boima ka 10-20 Shore A).

• Flame retardant (tekanyo ea UL94 V-0 ntle le li-additives tsa halogen).

• E boloka litšenyehelo ha e bapisoa le thermoplastics e khethehileng.

• Sistimi ea ho phekola e ka tloahelehang (e kentsoeng ka acid kapa e kentsoeng mocheso).

Lisebelisoa:

• Lithaere: Lik'hemik'hale tsa Sidewall (ho ntlafatsa ho hanyetsa, ASTM D624).

• Mabanta a Indasteri: Mabanta a conveyor bakeng sa tikoloho ea mocheso o phahameng (mohlala, limela tsa samente).

• Lisebelisoa tsa Friction: Brake pads (e boloka coefficient ea khohlano ho 0.35-0.45 tlas'a 200 ° C).

• Foundry: Li-binders tsa lehlabathe tsa mantlha (li fokotsa ho fetoha ha khase nakong ea ho lahlela).
