Hypophosphite ya Aluminium igabanya umuriro na MCA yo gukoresha EVA Heat-Shrink Tubing

Mu gihe ukoresha aluminium hypophosphite, MCA (melamine cyanurate), na magnesium hydroxide nk'ibintu bigabanya umuriro mu miyoboro ya EVA igabanya ubushyuhe, urugero rw'ibipimo n'amabwiriza yo kunoza ni ibi bikurikira:

1. Igipimo cy'ibiyobyabwenge bigabanya umuriro gisabwa

Hypophosfite ya aluminiyumu

• Igipimo:5%–10%
• Imikorere:Irinda umuriro neza cyane, itera imbaraga mu gukora ibishingwe, kandi igabanya umuvuduko wo kurekura ubushyuhe.
• Icyitonderwa:Ingano nyinshi ishobora kwangiza ubushobozi bw'ibikoresho; hagomba gushyirwamo ibintu bihuza ibikorwa kugira ngo birusheho kunozwa.

MCA (Melamine Cyanurate)

• Igipimo:10%–15%
• Imikorere:Irinda umuriro mu buryo bwa gaze, ifata ubushyuhe kandi igasohora imyuka idakora (urugero, NH₃), igahuza na aluminium hypophosphite kugira ngo yongere irinda umuriro.
• Icyitonderwa:Gushyiramo ibintu byinshi bishobora gutera kwimuka; hagomba kubaho ubwumvikane na EVA.

Magnesium Hydroxide (Mg(OH)₂)

• Igipimo:20%–30%
• Imikorere:Gusenyuka kwa endothermike bisohora umwuka w'amazi, bigakuraho imyuka ishobora gushya kandi bigakuraho umwotsi.
• Icyitonderwa:Gutwara ibintu byinshi bishobora kugabanya imiterere ya mekanike; guhindura ubuso birasabwa kugira ngo birusheho gukwirakwira neza.

2. Inama zo kunoza imikorere y'amafilimi

• Sisitemu yose igabanya umuriro:Ntibigomba kurenza 50% kugira ngo bihuze uburyo umuriro udakora neza kandi ushobore gucukurwa neza (urugero: guhindagurika, igipimo cyo kugabanuka).
• Ingaruka z'ubufatanye:
• Hypophosphite ya aluminiyumu na MCA bishobora kugabanya ingano y'ibipimo ku giti cyabyo (urugero, 8% ya aluminium hypophosphite + 12% ya MCA).
• Hydroxide ya manyeziyumu yuzuza ubukana bw'umuriro binyuze mu ngaruka za endothermike mu gihe igabanya umwotsi.
• Uburyo bwo kuvura ubuso:Ibikoresho byo guhuza silane bishobora kongera uburyo magnesium hydroxide ikwirakwiramo no guhuza imiterere yayo.
• Inyongeramusaruro:
• Ongeraho 2%–5% by'ibintu bihindura ibara ry'umukara (urugero, pentaerythritol) kugira ngo wongere ubushobozi bwo kugumana ibara ry'umukara.
• Shyiramo ingano nto ya pulasitiki (urugero, amavuta ya soya ya epoxidized) kugira ngo wishyure igabanuka ry'ubworoherane.

3. Amabwiriza yo kugenzura imikorere

• Isuzuma ry’uko umuriro udashobora guhagarara:
• Ikizamini cyo gutwika gihagaze cya UL94 (intego: V-0).
• Kugabanya igipimo cya ogisijeni (LOI >28%).
• Imiterere ya mekanike:
• Suzuma imbaraga zo gukurura no kurekura igihe cyo kuruhuka kugira ngo urebe ko ubworoherane buhuye n'ibisabwa mu ikoreshwa.
• Uburyo bwo gutunganya ibintu:
• Igenzura ry'Ingano y ...

4. Ibipimo by'Ikiguzi n'Ibidukikije

• Amafaranga asigaye:Hypophosphite ya aluminiyumu irahenze cyane; ingano yayo ishobora kugabanuka (yongerwaho na MCA) kugira ngo ikiguzi kigerweho.
• Kubungabunga ibidukikije:Hydroxide ya manyeziyumu ntabwo ihumanya kandi igabanya umwotsi, bigatuma ikoreshwa mu buryo butangiza ibidukikije.

Urugero rw'ikoreshwa ry'ibicuruzwa (ku buryo bwo kubikoresha gusa):

• Hypophosphate ya aluminiyumu: 8%
• MCA: 12%
• Hydroxide ya Manyeziyumu: 25%
• Matrix ya EVA: 50%
• Izindi nyongeramusaruro (ibikoresho bihuza, pulasitiki, nibindi): 5%
