Xalalka ka-hortagga ololka ee elastomer thermoplastic TPE

Xalalka ka-hortagga ololka ee elastomer thermoplastic TPE

Marka la isticmaalayo aluminium hypophosphite (AHP) iyo melamine cyanurate (MCA) ee thermoplastic elastomers (TPE) si loo gaaro heerka UL94 V0 ee ololka-celiya, waa lama huraan in la tixgeliyo habka ololka-celiya, iswaafajinta walxaha, iyo xaaladaha habaynta. Hoos waxaa ku qoran qaacidada lagu taliyay:

1. Rarista Caadiga ah Marka Si Gaar ah Loo Isticmaalo

Aluminium Hypophosphite (AHP)

• Soo raraya: 15-25%
• Astaamaha: Waxay kor u qaadaysaa sameynta qaab-dhismeedka, oo ku habboon nidaamyada u baahan waxqabadka farsamada sare, laakiin heerkulka habaynta waa in la xakameeyaa (lagu taliyaa ≤240°C).

Melamine Cyanurate (MCA)

• Soo raraya: 25-35%
• Astaamaha: Waxay ku tiirsan tahay burburka endothermic iyo barxadda gaaska; rarka badan wuxuu yareyn karaa dabacsanaanta walxaha.

2. Qaaciddada Isku-darka ee lagu taliyay

Saamiga Isku-darka AHP iyo MCA

• AHP: 10-15%
• MCA: 10-20%
• Wadarta rarka: 20-30%

Faa'iidooyinkaSaamaynta isku-dhafka ah waxay yareysaa rarista guud iyadoo yareyneysa saameynta sifooyinka farsamada (tusaale ahaan, xoogga jiidista, dabacsanaanta).

3. Arrimaha Muhiimka ah ee Saameeya

• Nooca Walxaha Saldhigga ah: TPE-yada ku salaysan SEBS guud ahaan way ka fudud yihiin in la joojiyo marka loo eego kuwa ku salaysan SBS, taasoo u oggolaanaysa rarista wax yar oo ka yar.
• Dhumucda Muunadda: U hoggaansanaanta UL94 V0 waa mid dhumucdeedu xasaasi tahay (1.6mm waa mid ka adag 3.2mm), sidaa darteed qaacidooyinka waa in si habboon loo hagaajiyaa.
• Dadka isku-xidhka sameeya: Ku darista 2-5% nano-dhul ama talc waxay kor u qaadi kartaa sameynta qurxin waxayna yareyn kartaa rarista dab-damiska.
• Heerkulka Habaynta: Hubi in heerkulka habayntu uu ka hooseeyo meelaha kala-go'a ee AHP (≤240°C) iyo MCA (≤300°C).

4. Tallaabooyinka Xaqiijinta ee lagu taliyay

• Tijaabada Hordhaca ah: Samee tijaabooyin yar yar oo leh AHP 12% + MCA 15% (wadarta guud 27%).
• Imtixaanka Waxqabadka: Qiimee dib-u-dhaca ololka (gubashada toosan ee UL94), adkaanta (Shore A), xoogga jiidista, iyo tusmada socodka dhalaalka.
• HagaajintaHaddii daadasho dhacdo, kordhi saamiga AHP (si kor loogu qaado daadashada); haddii sifooyinka farsamoyaqaanku ay liitaan, tixgeli inaad ku darto balaastig-sameeyayaasha ama aad yareyso wadarta guud ee rarka.

5. Taxaddarrada

• Iska ilaali inaad ku darto waxyaabaha lagu buuxiyo aashitada (tusaale ahaan, midabyo gaar ah), maadaama ay khalkhal gelin karaan AHP.
• Haddii TPE ay ku jirto xaddi badan oo balaastig ah oo saliid ku salaysan, rarista dab-damiska ayaa laga yaabaa in loo baahdo in la kordhiyo (saliiddu waxay yareyn kartaa hufnaanta dab-damiska).

Iyada oo loo marayo isku-darka macquulka ah iyo hagaajinta tijaabada, u hoggaansanaanta UL94 V0 waa la gaari karaa iyadoo la isku dheellitirayo habka wax-qabadka TPE iyo waxqabadka farsamada. Wadashaqeyn lala yeesho alaab-qeybiyeyaasha dab-damiska si loo helo xalal gaar ah ayaa lagula talinayaa.
