Awọn afikun Rubber: Awọn ohun-ini alaye, Awọn anfani, ati Awọn ohun elo

1. Zincoxide (ZnO)

Awọn ohun-ini:

• Funfun, lulú ti ko ni oorun pẹlu walẹ kan pato (5.6 g/cm³).

• Oju Iyọ: 1,975°C; atọka itọka: 2.008-2.029.

• Iṣe adaṣe ti o ga julọ bi imuṣiṣẹ vulcanization.

• UV-ìdènà ati antimicrobial-ini.

Awọn anfani:

• Mu vulcanization sulfur mu yara (dinku akoko imularada nipasẹ 20-30%).

• Ṣe ilọsiwaju awọn ohun-ini ẹrọ (agbara fifẹ + 15-25%, elongation ni isinmi + 10-15%).

• FDA-fọwọsi fun awọn ohun elo olubasọrọ ounjẹ (21 CFR 172.480).

• Ore ayika (ti kii ṣe majele, atunlo).

Awọn ohun elo:

• Awọn taya: Awọn okú taya radial ti irin-igi (ṣe imudara ifaramọ laarin roba ati irin).

• Aṣọ bàtà: Awọn agbo ogun ita (ṣe imudara resistance abrasion, ASTM D5963: 50–80 mm³ pipadanu).

• Iṣoogun: Awọn ibọwọ abẹ (aabo antimicrobial, ASTM E2149).

• Adhesives: Isopọ roba-si-irin (npo agbara peeli nipasẹ 30–40%).

2. Resini Phenolic

Awọn ohun-ini:

• Thermosetting polima pẹlu ga crosslink iwuwo.

• Ooru resistance: Lemọlemọfún lilo to 180°C (laarin 250°C).

• Rigiditi giga (modulu: 2-4 GPa) ati iduroṣinṣin onisẹpo.

• Idaabobo kemikali si awọn acids, awọn ipilẹ, ati awọn olomi.

Awọn anfani:

• Pese imuduro igbekalẹ (ṣe alekun lile nipasẹ 10–20 Shore A).

• Idaduro ina (oludiwọn UL94 V-0 laisi awọn afikun halogen).

• Iye owo-doko ni akawe si awọn thermoplastics pataki.

• Awọn ọna ṣiṣe itọju asefara (acid-catalyzed tabi ti mu ṣiṣẹ ooru).

Awọn ohun elo:

• Awọn taya: Awọn agbo ogun ẹgbẹ ẹgbẹ (ṣe ilọsiwaju idena gige, ASTM D624).

• Awọn igbanu ile-iṣẹ: Awọn igbanu gbigbe fun awọn agbegbe iwọn otutu (fun apẹẹrẹ, awọn ohun ọgbin simenti).

• Awọn ohun elo ikọlu: Awọn paadi biriki (ṣe itọju alasọdipúpọ ti ija ni 0.35-0.45 labẹ 200°C).

• Foundry: Core iyanrin binders (dinku itankalẹ gaasi nigba simẹnti).
