Ibisubizo bigabanya umuriro bya TPE ya thermoplastic elastomer

Ibisubizo bigabanya umuriro bya TPE ya thermoplastic elastomer

Mu gihe ukoresha aluminium hypophosphite (AHP) na melamine cyanurate (MCA) muri thermoplastic elastomers (TPE) kugira ngo ugere ku gipimo cya UL94 V0 cy’urumuri rudashira, ni ngombwa gusuzuma uburyo bwo kugabanya urumuri, guhuza ibikoresho, n’uburyo bwo kubitunganya. Hasi ni uburyo busabwa:

1. Gushyiramo ibintu bisanzwe iyo bikoreshejwe ku giti cyabyo

Hypophosfite ya Aluminium (AHP)

• Gupakira: 15-25%
• Ibiranga: Biteza imbere ikorwa ry'imashini, bikwiranye na sisitemu zisaba imikorere yo hejuru ya mekanike, ariko ubushyuhe bwo kuyitunganya bugomba kugenzurwa (byaba byiza ≤240°C).

Melamine Cyanurate (MCA)

• Gupakira: 25-35%
• Ibiranga: Bishingira ku kubora kw'ingufu no gushonga kwa gazi; umutwaro mwinshi ushobora kugabanya ubworoherane bw'ibikoresho.

2. Uburyo bwo kuvanga busabwa mu buryo buhuriweho

Igipimo cyo guhuza AHP na MCA

• AHP: 10-15%
• MCA: 10-20%
• Igiteranyo cy'ibicuruzwa: 20-30%

Ibyiza: Ingaruka za synergistic zigabanya umutwaro wose mu gihe zigabanya ingaruka ku miterere ya mekanike (urugero, imbaraga zo gukurura, uburimbane).

3. Ibintu by'ingenzi bigira ingaruka ku buzima

• Ubwoko bw'ibikoresho by'ibanze: TPE zishingiye kuri SEBS muri rusange zoroshye kuzimya umuriro kurusha izishingiye kuri SBS, bigatuma inyongera zigabanuka gato.
• Ubunini bw'icyitegererezo: Gukurikiza UL94 V0 bireba ubugari bw'ibipimo (1.6mm iragoye kurusha 3.2mm), bityo imiterere igomba guhindurwa hakurikijwe uko imeze.
• Abahuza ibikorwa: Kongeramo 2-5% by'ibumba rinini cyangwa talc bishobora kongera imiterere y'ibumba no kugabanya umuvuduko w'umuriro udashobora gukurura.
• Ubushyuhe bwo gutunganya: Menya neza ko ubushyuhe bwo gutunganya ibintu buguma munsi y’aho AHP (≤240°C) na MCA (≤300°C) bibora.

4. Intambwe zo kugenzura zisabwa

• Isuzuma ry'ibanze: Gukora igerageza rito hamwe na AHP 12% + MCA 15% (27%).
• Isuzuma ry'Imikorere: Suzuma uko umuriro udashobora gucika (UL94 vertical burning), ubukana (Inkombe A), imbaraga zo gukurura, n'ikimenyetso cy'amazi ashongeshejwe.
• Gutunganya neza: Iyo habayeho gutonyanga, ongera igipimo cya AHP (kugira ngo wongere umuriro); niba imiterere y'imashini ari mibi, tekereza kongeramo plasticizers cyangwa kugabanya umutwaro wose.

5. Amabwiriza yo kwirinda

• Irinde kuvanga n'ibintu bitera aside (urugero, bimwe mu bitera ibara), kuko bishobora gutuma AHP idakomera.
• Niba TPE irimo ingano nini ya pulasitiki ishingiye ku mavuta, umutwaro ugabanya umuriro ushobora gukenerwa kongerwa (amavuta ashobora kugabanya imikorere y’umuriro).

Binyuze mu kuvanga neza no kunoza igerageza, kubahiriza UL94 V0 bishobora kugerwaho mu gihe hakoreshwa uburyo bwo gutunganya TPE n'imikorere ya mekanike. Gukorana n'abatanga ibikoresho bigabanya umuriro mu gushaka ibisubizo byihariye birasabwa.
