Maganin retardant na harshen wuta don thermoplastic elastomer TPE
Lokacin amfani da aluminum hypophosphite (AHP) da melamine cyanurate (MCA) a cikin thermoplastic elastomers (TPE) don cimma ƙimar UL94 V0 mai ɗaukar harshen wuta, yana da mahimmanci a yi la'akari da injin mai ɗaukar harshen wuta, dacewa da kayan aiki, da yanayin sarrafawa. A ƙasa akwai tsarin da aka ba da shawarar:
1. Yawan Loading Lokacin Amfani Da Kowa
Aluminum Hypophosphite (AHP)
- Saukewa: 15-25%
- Halaye: Yana haɓaka haɓakar caja, dacewa da tsarin da ke buƙatar babban aikin injiniya, amma yakamata a sarrafa zafin aiki (wanda aka ba da shawarar ≤240°C).
Melamine Cyanurate (MCA)
- Lodawa: 25-35%
- Halaye: Ya dogara da bazuwar endothermic da dilution gas; babban lodi na iya rage sassaucin kayan aiki.
2. Shawarar Tsarin Haɗaɗɗen Haɗin kai
AHP da MCA Blending Ratio
- AHP: 10-15%
- MCA: 10-20%
- Jimlar lodi: 20-30%
Amfani: Tasirin haɗin gwiwa yana rage jimlar lodi yayin da rage tasiri akan kaddarorin inji (misali, ƙarfin ƙarfi, elasticity).
3. Mahimman Abubuwan Tasiri
- Nau'in Material Base: TPEs na tushen SEBS gabaɗaya sun fi sauƙi don kashe wuta fiye da na tushen SBS, suna ba da izinin ƙara ƙaramin ƙara.
- Misalin Kauri: UL94 V0 yarda yana da kauri-m (1.6mm ya fi ƙalubale fiye da 3.2mm), don haka dole ne a daidaita tsari daidai.
- Masu haɗin gwiwa: Ƙara 2-5% nano-laka ko talc na iya haɓaka samuwar char kuma rage ɗaukar wuta.
- Tsarin Zazzabi: Tabbatar cewa yanayin zafi ya kasance ƙasa da wuraren bazuwar AHP (≤240°C) da MCA (≤300°C).
4. Shawarwari Matakan Tabbatarwa
- Gwaji na farko: Gudanar da ƙananan gwaji tare da AHP 12% + MCA 15% (jimlar 27%).
- Gwajin Aiki: Ƙimar jinkirin harshen wuta (UL94 a tsaye ƙonawa), taurin ( Shore A), ƙarfin ƙarfi, da ma'anar narke kwarara.
- Ingantawa: Idan dripping ya faru, ƙara AHP rabo (don haɓaka caji); idan kayan aikin injiniya ba su da kyau, yi la'akari da ƙara masu filastik ko rage yawan lodi.
5. Hattara
- Guji haɗawa tare da masu cika acidic (misali, wasu masu launi), saboda suna iya lalata AHP.
- Idan TPE ya ƙunshi ɗimbin robobi na tushen mai, ƙila za a iya ƙara ɗora lodin wuta (man zai iya rage ƙimar jinkirin harshen wuta).
Ta hanyar haɗakarwa ta hankali da haɓaka gwaji, ana iya samun yardawar UL94 V0 yayin daidaita aiwatar da TPE da aikin injiniya. Ana ba da shawarar haɗin kai tare da masu samar da wutar lantarki don keɓantaccen mafita.
