Nigute ushobora kugabanya umwotsi wumwotsi kuri epoxy ifata hamwe na flame retardant AHP na MCA?

Kwiyongera kwa aluminium hypophosphite na MCA kuri epoxy adhesive bivamo imyuka myinshi. Gukoresha zinc borate kugirango ugabanye ubwinshi bwumwotsi nibisohoka birashoboka, ariko formulaire ihari igomba kuba nziza kugirango igereranyo.

1. Uburyo bwo Kurwanya Umwotsi Uburyo bwa Zinc Borate

Zinc borate nikintu cyiza cyo guhagarika umwotsi hamwe na flame-retardant synergist. Uburyo bukoreshwa harimo:

• Gutezimbere gushiraho: Ikora char layer yuzuye mugihe cyo gutwikwa, gutandukanya ogisijeni nubushyuhe, no kugabanya imyuka yaka umuriro.
• Kubuza umwotsi.
• Ingaruka yo Guhuza: Yongera ububobere bwa flame iyo ihujwe na fosifore (urugero, aluminium hypophosphite) hamwe na azote ishingiye kuri azote (urugero, MCA).

2. Ubundi buryo cyangwa ubundi buryo bwo kongera umwotsi

Kugirango urusheho kunoza uburyo bwo guhagarika umwotsi, suzuma ibisubizo bikurikira:

• Molybdenum(urugero, zinc molybdate, molybdenum trioxide): Bikora neza kuruta zinc borate ariko ihenze; basabwe kuvanga na zinc borate (urugero, zinc borate: zinc molybdate = 2: 1).
• Aluminium / Magnesium Hydroxide: Irasaba ibintu byinshi (20-40 interuro), bishobora kugira ingaruka kumikorere ya epoxy-ihindure witonze.

3. Basabwe Guhindura Imiterere

Dufashe ko umwimerere arialuminium hypophosphite + MCA, hano hari icyerekezo cyiza (gishingiye kubice 100 epoxy resin):

Ihitamo 1: Kwiyongera kwa Zinc Borate

• Aluminium hypophosphite: Mugabanye kuva kuri 20-30 kugeza15-25 interuro
• MCA: Mugabanye kuva 10-15 interuro kugeza8-12 interuro
• Zinc borate: Ongeraho5-15 interuro(tangira kwipimisha kuri interuro 10)
• Ibirimi byose byaka umuriro: Komeza30-40 interuro(irinde amafaranga arenze urugero agira ingaruka kumikorere).

Ihitamo 2: Zinc Borate + Zinc Molybdate Synergy

• Aluminium hypophosphite:15-20 interuro
• MCA:5-10 interuro
• Zinc borate:8-12 interuro
• Zinc molybdate:4-6 interuro
• Ibirimi byose byaka umuriro:30-35 interuro.

4. Ibipimo by'ingenzi byo Kwemeza

• Ikirimi cy'umuriro: UL-94 gutwika guhagaritse, ibizamini bya LOI (intego: V-0 cyangwa LOI> 30%).
• Ubucucike bw'umwotsi: Koresha igeragezwa ryumwotsi (urugero, icyumba cyumwotsi wa NBS) kugirango ugabanye kugabanuka kwurwego rwumwotsi (SDR).
• Ibikoresho bya mashini: Menya neza imbaraga zingirakamaro hamwe nimbaraga zifatika zujuje ibisabwa nyuma yo gukira.
• Inzira: Emeza ikwirakwizwa rimwe ryumuriro utagira ingaruka ku bwiza cyangwa igihe cyo gukiza.

5. Ibitekerezo

• Ingano yubunini bugenzura: Hitamo kuri nano-nini ya zinc borate (urugero, ingano ya <1 μ m) kugirango utezimbere.
• Guhindura Ubuso: Koresha zinc borate hamwe na silane ihuza agent kugirango wongere ubwuzuzanye na epoxy resin.
• Kubahiriza amabwiriza: Menya neza ko umuriro watoranijwe wujuje RoHS, REACH, nandi mabwiriza.

6. Gutanga urugero (Reba)

7. Incamake

• Zinc borate ni amahitamo meza yo kugabanya imyuka ihumanya. Saba kongeraho10-15 interuromugihe ugabanije muburyo bwa aluminium hypophosphite / MCA ibirimo.
• Kugirango urusheho guhagarika umwotsi, vanga hamwe na molybdenum (urugero,4-6 interuro).
• Kwemeza ubushakashatsi birakenewe kugirango habeho kuringaniza umuriro, guhagarika umwotsi, hamwe nubukanishi.
