Mayankho oletsa moto a thermoplastic elastomer TPE

Mayankho oletsa moto a thermoplastic elastomer TPE

Mukamagwiritsa ntchito aluminium hypophosphite (AHP) ndi melamine cyanurate (MCA) mu thermoplastic elastomers (TPE) kuti mukwaniritse UL94 V0 retardant rating, ndikofunikira kuganizira momwe zimawotchera moto, kugwirizana kwa zinthu, ndi momwe zimapangidwira. M'munsimu ndi momwe mungapangire:

1. Kuyika Kwachizoloŵezi Pamene Kugwiritsidwa Ntchito Payekha

Aluminium Hypophosphite (AHP)

• Kutumiza: 15-25%
• Makhalidwe: Imalimbikitsa mapangidwe a char, oyenera machitidwe omwe amafunikira makina apamwamba kwambiri, koma kutentha kwa kutentha kuyenera kuyendetsedwa (kukulimbikitsidwa ≤240 ° C).

Melamine Cyanurate (MCA)

• Kutumiza: 25-35%
• Makhalidwe: Zimadalira kuwonongeka kwa endothermic ndi kusungunuka kwa mpweya; kukweza kwambiri kungachepetse kusinthasintha kwazinthu.

2. Analimbikitsa Synergistic Blending Formula

AHP ndi MCA Blending Ratio

• AHP: 10-15%
• MCA: 10-20%
• Kutsegula kwathunthu: 20-30%

Ubwino wake: Mphamvu ya Synergistic imachepetsa kutsitsa kwathunthu ndikuchepetsa kukhudzidwa kwamakina (mwachitsanzo, kulimba kwamphamvu, kukhazikika).

3. Zinthu Zofunika Kwambiri

• Mtundu wa Zinthu Zoyambira: Ma TPE opangidwa ndi SEBS nthawi zambiri amakhala osavuta kuyimitsa moto kuposa omwe ali ndi SBS, zomwe zimaloleza kutsitsa pang'ono kowonjezera.
• Zitsanzo Makulidwe: Kutsata kwa UL94 V0 ndikovuta kwambiri (1.6mm ndizovuta kuposa 3.2mm), kotero mapangidwe amayenera kusinthidwa moyenera.
• Synergists: Kuwonjezera 2-5% nano-dongo kapena talc kumatha kupititsa patsogolo mapangidwe a char ndikuchepetsa kutsitsa kwamoto.
• Processing Kutentha: Onetsetsani kuti kutentha kwa kutentha kumakhala pansi pazigawo zowonongeka za AHP (≤240 ° C) ndi MCA (≤300 ° C).

4. Analimbikitsa Kutsimikizira Masitepe

• Kuyesedwa koyambirira: Chitani mayeso ang'onoang'ono ndi AHP 12% + MCA 15% (yonse 27%).
• Kuyesa Magwiridwe: Unikani kuchedwa kwa lawi (UL94 kuwotcha kowongoka), kuuma (Shore A), kulimba kwamphamvu, ndi kusungunula kutulutsa index.
• Kukhathamiritsa: Ngati kudontha kumachitika, onjezani chiŵerengero cha AHP (kuwonjezera charring); ngati makina ali otsika, ganizirani kuwonjezera mapulasitiki kapena kuchepetsa kudzaza kwathunthu.

5. Njira zodzitetezera

• Pewani kuphatikiza ndi zodzaza acidic (mwachitsanzo, zopaka utoto zina), chifukwa zitha kusokoneza AHP.
• Ngati TPE ili ndi mapulasitiki ochuluka opangidwa ndi mafuta, kutsekemera kwamoto kungafunikire kuwonjezereka (mafuta amachepetsa mphamvu ya retardancy).

Kupyolera mu kusakaniza koyenera ndi kukhathamiritsa koyesera, kutsata kwa UL94 V0 kungathe kukwaniritsidwa ndikugwirizanitsa kusinthasintha kwa TPE ndi machitidwe a makina. Kugwirizana ndi ogulitsa omwe amawotcha moto kuti athetse makonda awo ndikulimbikitsidwa.
