Mpira yogwira ntchito amadziwikanso kuti vulcanizing yogwira wothandizira. Chinthu chopangidwa ndi organic kapena organic chomwe chimagwiritsidwa ntchito kuti vulcanization accelerator igwire ntchito. Itha kukulitsa mphamvu ya accelerator, kuchepetsa kuchuluka kwa accelerator, ndikufupikitsa nthawi ya vulcanization. Zambiri mwazinthu zowonjezera ndi zitsulo zachitsulo, hydroxides ndi carbonates zofunika, monga zinc oxide, lead oxide, calcium hydroxide, lead carbonate, etc., chinthu chofunika kwambiri mu zowonjezera zowonjezera ndi mafuta acids, otsatiridwa ndi amines, sopo, etc. Monga stearic acid, dibutyloleic acid amine, zinc stearate, etc. 5% ya kulemera kwa rabara.

Zowonjezera za Rubber: Katundu Watsatanetsatane, Ubwino, ndi Ntchito

1. Zinc oxide (ZnO)

Katundu:

• Ufa woyera, wopanda fungo wokhala ndi mphamvu yokoka inayake (5.6 g/cm³).

• Malo osungunuka: 1,975 ° C; refractive index: 2.008-2.029.

• High reactivity ngati vulcanization activator.

• UV-blocking ndi antimicrobial properties.

Ubwino:

• Imathandizira sulfure vulcanization (imachepetsa nthawi yochiritsa ndi 20-30%).

• Kupititsa patsogolo makina (mphamvu yamakina + 15-25%, elongation panthawi yopuma + 10-15%).

• FDA-yovomerezeka pazakudya zolumikizana ndi chakudya (21 CFR 172.480).

• Zosamalidwa ndi chilengedwe (zopanda poizoni, zobwezerezedwanso).

Mapulogalamu:

• Matayala: Mitembo ya matayala okhala ndi malamba achitsulo (amawonjezera kumatira pakati pa mphira ndi chitsulo).

• Nsapato: Zida za Outsole (zimathandizira kukana kwa abrasion, ASTM D5963: 50-80 mm³ kutaya).

• Zamankhwala: Magolovesi opangira opaleshoni (chitetezo cha antimicrobial, ASTM E2149).

• Zomatira: Kulumikizana kwa mphira ndi chitsulo (kumawonjezera mphamvu ya peel ndi 30-40%).

2. Phenolic Resin

Katundu:

• Thermosetting polima yokhala ndi kachulukidwe kakang'ono kwambiri.

• Kukana kutentha: Kugwiritsa ntchito mosalekeza mpaka 180 ° C (pakatikati 250 ° C).

• Kukhazikika kwakukulu (modulus: 2-4 GPa) ndi kukhazikika kwazithunzi.

• Chemical kukana kwa zidulo, maziko, ndi zosungunulira.

Ubwino:

• Amapereka kulimbitsa kwamapangidwe (amawonjezera kuuma ndi 10-20 Shore A).

• Flame retardant (UL94 V-0 rating popanda zowonjezera za halogen).

• Zotsika mtengo poyerekeza ndi zapaderazi za thermoplastics.

• Customizable machiritso machitidwe (acid-catalyzed kapena kutentha adamulowetsa).

Mapulogalamu:

• Matayala: Zida zam'mbali (zimathandizira kukana, ASTM D624).

• Malamba akumafakitale: Malamba otengera malo otentha kwambiri (mwachitsanzo, zomangira simenti).

• Zida Zamkangano: Ma brake pads (amasunga coefficient of friction pa 0.35-0.45 pansi pa 200 ° C).

• Foundry: Zomangira mchenga zamchenga (zimachepetsa kusintha kwa gasi panthawi yoponya).
