Halogen idafite flame retardant yerekana uburyo bwo gukoresha amazi ashingiye kuri acrylic electronique

Muri sisitemu ya acrylic ishingiye kumazi, umubare winyongera wa aluminium hypophosphite (AHP) na zinc borate (ZB) ugomba kugenwa hashingiwe kubisabwa byihariye (nko kugereranya flame retardancy rating, coating thick, ibisabwa kumikorere, nibindi) hamwe ningaruka zabyo. Hano hepfo ibyifuzo rusange hamwe nurwego:

I. Ibyingenzi Byongeweho Amafaranga Yerekana

Imbonerahamwe: Basabye Flame Retardant Yongeyeho nibisobanuro

II. Gukwirakwiza ibipimo ngereranyo

1. Ikigereranyo gisanzwe:

• AHP: ZB = 2: 1 ~ 4: 1(urugero, 15% AHP + 5% ZB, yose hamwe 20%).
• Hindura ibipimo mubigeragezo, kurugero:
• Icyifuzo cyo kutagira umuriro mwinshi:AHP 15% ~ 20%, ZB 5% ~ 8%.
• Kuringaniza ibintu bifatika:AHP 10% ~ 15%, ZB 3% ~ 5%.

1. Ingaruka zo Guhuza:

• Zinc borate yongerera umuriro imbaraga:
• Gutezimbere gushiraho char (gukorana na fosifate ya aluminium yakozwe na AHP).
• Kurekura amazi aboshye kugirango akuremo ubushyuhe no kugabanya imyuka yaka.

III. Intambwe yo Kwemeza Intambwe

1. Kwipimisha Intambwe:

• Ikizamini cya buri muntu:Banza usuzume AHP (5% ~ 20%) cyangwa ZB (5% ~ 15%) ukwayo kugirango ubuze umuriro (UL-94, LOI) hamwe nuburyo bwo gutwikira (gufatira, gukomera, kurwanya amazi).
• Gukwirakwiza ibintu neza:Nyuma yo guhitamo ibipimo fatizo bya AHP, ongera wongereho ZB (urugero, 3% kugeza 8% mugihe AHP ari 15%) hanyuma urebe iterambere ryokwirinda umuriro ningaruka mbi.

1. Ibipimo by'ingenzi byerekana imikorere:

• Kubura umuriro:LOI (intego ≥28%), UL-94 igipimo (V-0 / V-1), ubwinshi bwumwotsi.
• Imiterere yumubiri:Gukora firime, gufatira (ASTM D3359), kurwanya amazi (nta gusiba nyuma yo kwibizwa 48h).

IV. Ibitekerezo by'ingenzi

• Gutandukana:
• AHP ni hygroscopique-mbere yumye cyangwa ikoresha ubuso bwahinduwe.
• Koresha ibitatanye (urugero, BYK-190, TEGO Dispers 750W) kugirango utezimbere uburinganire no gukumira ubutayu.
• pH Guhuza:
• Sisitemu ishingiye kumazi ya acrylic mubusanzwe ifite pH ya 8-9; menya neza ko AHP na ZB biguma bihamye (irinde hydrolysis cyangwa kubora).
• Kubahiriza amabwiriza:
• AHP igomba kuba yujuje ibisabwa na RoHS ibisabwa; ZB igomba gukoresha amanota make aremereye-yicyuma.

V. Ibindi bisubizo cyangwa ibisubizo byinyongera

• Melamine Polyphosphate (MPP):Irashobora kongera imbaraga zo kutagira umuriro iyo uhujwe na AHP (urugero, 10% AHP + 5% MPP + 3% ZB).
• Nano Flame Retardants:Nano-urwego ZB (inyongera yagabanutse kugera kuri 1% ~ 3%) cyangwa hydroxide ya kabiri (LDH) kugirango igabanye ingaruka nziza.

VI. Incamake Ibyifuzo

• Gutangira gutegura:AHP 10% ~ 15% + ZB 3% ~ 5% (yose hamwe 13% ~ 20%), hanyuma uhindure neza.
• Uburyo bwo kwemeza:Gerageza ingero ntoya kuri LOI na UL-94 mugihe usuzuma imiterere yubukanishi.
