Ni gute wagabanya ubucucike bw'umwotsi kuri kole ya epoxy ukoresheje AHP na MCA igabanya umuriro?

Kongeramo aluminium hypophosphite na MCA muri epoxy adhesive bituma habaho umwotsi mwinshi. Gukoresha zinc borate kugira ngo ugabanye ubucucike bw'umwotsi n'imyotsi isohoka birashoboka, ariko uburyo busanzwe bwo gukora bugomba kunozwa hakurikijwe igipimo.

1. Uburyo bwo gukumira umwotsi bwa Zinc Borate

Zinc borate ni umuti ugabanya umwotsi neza kandi utuma umuriro udashira. Uburyo ikora burimo:

• Guteza imbere ireme ry'imibanire ya Char: Ikora urwego rw'ingufu nyinshi mu gihe cyo gutwika, ikagabanya ogisijeni n'ubushyuhe, kandi ikagabanya irekurwa rya gaze ishobora gushya.
• Kubuza umwotsi: Itera imbaraga mu guhuza ibintu kugira ngo igabanye umwotsi, ikagabanya ubucucike bw'umwotsi (cyane cyane bigira ingaruka nziza kuri polymer nka epoxy).
• Ingaruka z'ubufatanye: Yongera ubushobozi bwo kudakora neza kw'umuriro iyo ihujwe n'ibintu bikomoka kuri fosifore (urugero: aluminium hypophosphite) n'ibikomoka kuri azote (urugero: MCA) bigabanya umuriro.

2. Imiti igabanya umwotsi cyangwa iyiyongeraho

Kugira ngo umwotsi urusheho kuryoha, tekereza ku bisubizo bikurikira bihuriweho:

• Ibinyabutabire bya Molybdenum(urugero, zinc molybdate, molybdenum trioxide): Ifite akamaro kurusha zinc borate ariko irahenze; ​​irasabwa kuvanga na zinc borate (urugero, zinc borate: zinc molybdate = 2:1).
• Aluminium/Magnesium Hydroxide: Isaba umutwaro mwinshi (20-40 phr), ibi bishobora kugira ingaruka ku miterere ya epoxy—hindura witonze.

3. Ivugurura ry’imyandikire risabwa

Dufashe ko uburyo bw'umwimerere arialuminium hypophosphite + MCA, dore amabwiriza yo kunoza (ashingiye ku bice 100 bya epoxy resin):

Uburyo bwa 1: Kongeramo Zinc Borate mu buryo butaziguye

• Hypophosphite ya aluminiyumu: Gabanya kuva kuri 20-30 phr kugeza kuriAmasomo 15-25
• MCA: Kugabanya kuva kuri 10-15 hr kugera kuriIbice 8-12
• Borate ya Zinc: OngerahoAmasomo 5-15(tangira ikizamini ku isaha ya saa kumi)
• Igiteranyo cy'ibidashira by'umuriroKomeza kuriAmasomo 30-40(irinde ko bitagira ingaruka ku mikorere y'ubukorikori).

Uburyo bwa 2: Zinc Borate + Zinc Molybdate Synergy

• Hypophosite ya aluminiyumu:Amasomo 15-20
• MCA:Ibice 5-10
• Borate ya zinki:Ibice 8-12
• Molibdate ya zinki:Ibice 4-6
• Igiteranyo cy'ibidashira by'umuriro:Amasomo 30-35.

4. Ibipimo by'ingenzi byo kwemeza

• Gutinda k'umuriro: Gutwika UL-94 mu buryo buhagaze, ibizamini bya LOI (intego: V-0 cyangwa LOI >30%).
• Ubucucike bw'umwotsi: Koresha icyuma gipima ubucucike bw'umwotsi (urugero, icyumba cy'umwotsi cya NBS) kugira ngo ugereranye igabanuka ry'ubucucike bw'umwotsi (SDR).
• Imiterere ya mekanike: Menya neza ko imbaraga zo gukurura n'imbaraga zo gufatana byujuje ibisabwa nyuma yo gushya.
• Uburyo bwo gutunganya ibintu: Emeza ko ibintu bigabanya umuriro bikwirakwira kimwe nta ngaruka ku bushyuhe cyangwa igihe cyo gushya.

5. Ibigomba kwitabwaho

• Kugenzura Ingano y'Ibice by'Uduce: Hitamo borate ya zinc ingana nano (urugero, ingano y'uduce <1 μm) kugira ngo wongere ikwirakwira ry'ibimera.
• Guhindura Ubuso: Sukura zinc borate ukoresheje silane coupling agent kugira ngo wongere imikoranire na epoxy resin.
• Iyubahirizwa ry'amategeko agenga iyubahirizwa ry'amategeko: Kureba neza ko ibikoresho bigabanya umuriro byatoranijwe byujuje amabwiriza ya RoHS, REACH, n'andi mategeko.

6. Urugero rw'incamake (Icyitonderwa)

7. Incamake

• Zinc borate ni amahitamo meza yo kugabanya imyuka ihumanya umwotsi. Ndagusaba kongeramoAmasomo 10-15mu gihe hagabanywa ku rugero ruto ingano ya aluminiyumu hypophosphite/MCA.
• Kugira ngo umwotsi ukomeze kugabanuka, vanga n'ibinyabutabire bya molybdenum (urugero,Ibice 4-6).
• Kwemeza igerageza ni ngombwa kugira ngo harebwe uburyo umuriro udakora neza, uburyo umwotsi ugabanuka, n'imiterere ya mekanike.
