Mayankho oletsa moto a TPE ya thermoplastic elastomer

Mukamagwiritsa ntchito aluminium hypophosphite (AHP) ndi melamine cyanurate (MCA) mu thermoplastic elastomers (TPE) kuti mupeze UL94 V0 flame-retardant rating, ndikofunikira kuganizira momwe zimagwirira ntchito, momwe zinthu zikuyendera, komanso momwe zimagwirira ntchito. Pansipa pali njira yolimbikitsira:

1. Kuyika Kwachizolowezi Mukagwiritsa Ntchito Payekha

Aluminium Hypophosphite (AHP)

• Kutsegula: 15-25%
• Makhalidwe: Amalimbikitsa kupangika kwa char, yoyenera machitidwe omwe amafuna magwiridwe antchito apamwamba amakina, koma kutentha kwa kukonza kuyenera kulamulidwa (koyenera ≤240°C).

Melamine Cyanurate (MCA)

• Kutsegula: 25-35%
• Makhalidwe: Amadalira kuwonongeka kwa endothermic ndi kusungunuka kwa mpweya; katundu wambiri amachepetsa kusinthasintha kwa zinthu.

2. Fomula Yopangira Kuphatikizana Yogwirizana

Chiŵerengero Chosakaniza cha AHP ndi MCA

• AHP: 10-15%
• MCA: 10-20%
• Kuchuluka kwa katundu: 20-30%

Ubwino: Mphamvu yogwirizana imachepetsa katundu wonse pamene ikuchepetsa kukhudzidwa kwa mphamvu zamakanika (monga mphamvu yokoka, kusinthasintha).

3. Zinthu Zofunika Kwambiri Zokhudza Kugonana

• Mtundu wa Zinthu Zoyambira: Ma TPE okhala ndi SEBS nthawi zambiri amakhala osavuta kuwaletsa moto kuposa omwe ali ndi SBS, zomwe zimapangitsa kuti zowonjezera zikhale zochepa pang'ono.
• Kunenepa kwa Chitsanzo: Kutsatira malamulo a UL94 V0 kumadalira makulidwe (1.6mm ndi yovuta kuposa 3.2mm), kotero mapangidwe ayenera kusinthidwa moyenerera.
• Ogwirizana: Kuwonjezera 2-5% nano-dongo kapena talc kungathandize kukulitsa kapangidwe ka char ndikuchepetsa kudzaza kwa lawi.
• Kutentha KwambiriOnetsetsani kuti kutentha kwa kukonza kumakhalabe pansi pa malo owonongeka a AHP (≤240°C) ndi MCA (≤300°C).

4. Njira Zovomerezeka Zotsimikizira

• Kuyesa KoyambiriraChitani mayeso ang'onoang'ono ndi AHP 12% + MCA 15% (onse 27%).
• Kuyesa Magwiridwe Antchito: Yesani kuchedwa kwa moto (UL94 vertical burn), kuuma (Shore A), mphamvu yokoka, ndi index ya kusungunuka kwa madzi.
• Kukonza bwinoNgati madzi akutuluka, onjezerani chiŵerengero cha AHP (kuti muwonjezere kutentha); ngati zinthu zamakina sizili bwino, ganizirani kuwonjezera mapulasitiki kapena kuchepetsa katundu wonse.

5. Zodzitetezera

• Pewani kusakaniza ndi zodzaza ndi asidi (monga, mitundu ina), chifukwa zimatha kusokoneza AHP.
• Ngati TPE ili ndi mapulasitiki ambiri ochokera ku mafuta, katundu woletsa moto ungafunike kuwonjezeredwa (mafuta amatha kuchepetsa mphamvu yoletsa moto).

Kudzera mu kusakaniza mwanzeru komanso kukonza bwino zinthu pogwiritsa ntchito njira zoyesera, kutsatira malamulo a UL94 V0 kungatheke poyesa kusinthasintha kwa TPE ndi magwiridwe antchito a makina. Kugwirizana ndi ogulitsa omwe amaletsa moto kuti apeze njira zomwe zasinthidwa ndikofunikira.
