Aluminium Hypophosphite yoletsa moto ndi MCA ya EVA Heat-Shrink Tubing

Aluminium Hypophosphite yoletsa moto ndi MCA ya EVA Heat-Shrink Tubing

Mukagwiritsa ntchito aluminium hypophosphite, MCA (melamine cyanurate), ndi magnesium hydroxide ngati zoletsa moto mu chubu chochepetsa kutentha cha EVA, mulingo woyenera wa mlingo ndi malangizo ogwiritsira ntchito bwino ndi awa:

1. Mlingo Wovomerezeka wa Zoletsa Moto

Aluminiyamu Hypophosphite

• Mlingo:5%–10%
• Ntchito:Yogwira ntchito kwambiri yoletsa moto, imalimbikitsa kupanga ma char, komanso imachepetsa kutentha komwe kumatuluka.
• Zindikirani:Kuchuluka kwambiri kungasokoneze kusinthasintha kwa zinthu; zinthu zogwirizanitsa ziyenera kuyikidwa kuti zigwiritsidwe ntchito bwino.

MCA (Melamine Cyanurate)

• Mlingo:10%–15%
• Ntchito:Choletsa moto cha gawo la gasi, chimayamwa kutentha ndikutulutsa mpweya wosagwira ntchito (monga NH₃), chimagwirizana ndi aluminium hypophosphite kuti chiwonjezere kuletsa moto.
• Zindikirani:Kudzaza zinthu mopitirira muyeso kungayambitse kusamuka; kuyenera kutsimikizika kuti kukugwirizana ndi EVA.

Magnesium Hydroxide (Mg(OH)₂)

• Mlingo:20%–30%
• Ntchito:Kuwonongeka kwa endothermic kumatulutsa nthunzi ya madzi, kumachepetsa mpweya woyaka moto ndikuletsa utsi.
• Zindikirani:Kulemera kwambiri kungachepetse mphamvu za makina; kusintha kwa pamwamba kumalimbikitsidwa kuti kukhale bwino pofalitsa.

2. Malangizo Okonza Mapangidwe

• Dongosolo Lonse Loletsa Moto:Siziyenera kupitirira 50% kuti zigwirizane ndi kuchedwa kwa moto ndi kuthekera kokonza (monga kusinthasintha, kuchuluka kwa kuchepa).
• Zotsatira Zogwirizana:
• Aluminium hypophosphite ndi MCA zimatha kuchepetsa mlingo uliwonse (monga, 8% aluminiyamu hypophosphite + 12% MCA).
• Magnesium hydroxide imathandizira kuletsa moto kudzera mu endothermic effects pomwe imachepetsa utsi.
• Chithandizo cha pamwamba:Zolumikizira za silane zimatha kukulitsa kufalikira ndi kulumikizidwa kwa magnesium hydroxide pakati pa zinthu.
• Zowonjezera Zothandizira:
• Onjezani 2%–5% ya zinthu zopangira char (monga pentaerythritol) kuti muwongolere kukhazikika kwa char layer.
• Phatikizani zinthu zopukutira pulasitiki pang'ono (monga mafuta a soya osungunuka) kuti muchepetse kusinthasintha kwa kutentha.

3. Malangizo Otsimikizira Magwiridwe Antchito

• Kuyesa Kubwerera kwa Moto:
• Mayeso oyatsa moto olunjika a UL94 (chandamale: V-0).
• Kuchepetsa Oxygen Index (LOI >28%).
• Katundu wa Makina:
• Unikani mphamvu yokoka ndi kutalika kwake panthawi yopuma kuti muwonetsetse kuti kusinthasintha kwake kukukwaniritsa zofunikira pakugwiritsa ntchito.
• Kuthekera kwa kukonza:
• Monitor Melt Flow Index (MFI) kuti tipewe mavuto okonza chifukwa cha kuchuluka kwa ma filler.

4. Zofunika Kuganizira pa Mtengo ndi Zachilengedwe

• Ndalama Zotsala:Aluminium hypophosphite ndi yokwera mtengo; mlingo wake ukhoza kuchepetsedwa (wowonjezeredwa ndi MCA) kuti muwongolere ndalama.
• Ubwino wa Chilengedwe:Magnesium hydroxide si poizoni komanso imaletsa utsi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosasamala chilengedwe.

Chitsanzo cha Kupanga (chongogwiritsidwa ntchito kokha):

• Aluminiyamu Hypophosphate: 8%
• MCA: 12%
• Magnesium Hydroxide: 25%
• Matrix ya EVA: 50%
• Zowonjezera Zina (zolumikizira, mapulasitiki, ndi zina zotero): 5%
