Aluminum Hypophosphite mai ɗaukar wuta da MCA don EVA Heat-Srink Tubing
Lokacin amfani da aluminium hypophosphite, MCA (melamine cyanurate), da magnesium hydroxide a matsayin masu kare wuta a cikin bututun zafi na EVA, adadin adadin da aka ba da shawarar da ingantattun kwatance sune kamar haka:
1. Shawarar Sashi na Masu Retardawan Wuta
Aluminum Hypophosphite
- Sashi:5% - 10%
- Aiki:Ingantacciyar haɓakar harshen wuta, yana haɓaka haɓakar char, kuma yana rage yawan sakin zafi.
- Lura:Yawan yawa na iya lalata sassauƙar kayan aiki; Dole ne a haɗa wakilai na haɗin gwiwa don haɓakawa.
MCA (Melamine Cyanurate)
- Sashi:10% -15%
- Aiki:Gas-lokaci harshen wuta retardant, sha zafi da saki inert gas (misali, NH₃), synergizing da aluminum hypophosphite don inganta harshen wuta.
- Lura:Yin lodi zai iya haifar da ƙaura; Dole ne a tabbatar da dacewa da EVA.
Magnesium Hydroxide (Mg (OH) ₂)
- Sashi:20% - 30%
- Aiki:Bazuwar Endothermic yana fitar da tururin ruwa, yana diluting gas mai ƙonewa da kuma hana hayaki.
- Lura:High loading iya rage inji Properties; Ana ba da shawarar gyara ƙasa don inganta tarwatsewa.
2. Shawarwarin Haɓaka Ƙirƙiri
- Jimlar Tsarin Tsare Wuta:Kada ya wuce 50% don daidaita jinkirin harshen wuta da iya aiki (misali, sassauci, ƙimar raguwa).
- Tasirin Haɗin Kai:
- Aluminum hypophosphite da MCA na iya rage adadin mutum ɗaya (misali, 8% hypophosphite aluminum + 12% MCA).
- Magnesium hydroxide yana haɓaka jinkirin harshen wuta ta hanyar tasirin endothermic yayin rage hayaki.
- Maganin Sama:Silane hada biyu jamiái na iya inganta watsawa da interfacial bonding na magnesium hydroxide.
- Ƙarin Ƙari:
- Ƙara 2%-5% masu yin char (misali, pentaerythritol) don inganta kwanciyar hankali na char.
- Haɗa ƙananan ƙwayoyin robobi (misali, man waken soya mai lalacewa) don ramawa ga asarar sassauci.
3. Jagoran Tabbatar da Aiki
- Gwajin Ciwon Harshe:
- Gwajin ƙona UL94 a tsaye (manufa: V-0).
- Ƙayyadaddun Oxygen Index (LOI> 28%).
- Kayayyakin Injini:
- Yi la'akari da ƙarfi da tsayin daka a lokacin hutu don tabbatar da sassauci ya dace da bukatun aikace-aikacen.
- Yin aiki:
- Saka idanu Index ɗin Raɗawar Ruwa (MFI) don guje wa matsalolin sarrafawa saboda yawan abubuwan cikawa.
4. Kudi da La'akarin Muhalli
- Daidaiton Farashi:Aluminum hypophosphite yana da tsada sosai; ana iya rage adadin sa (wanda aka haɗa da MCA) don sarrafa farashi.
- Abokan Muhalli:Magnesium hydroxide ba mai guba ba ne kuma yana hana hayaki, yana sa ya dace da aikace-aikacen abokantaka na muhalli.
Misali Formulation (don tunani kawai):
- Aluminum Hypophosphite: 8%
- MCA: 12%
- Magnesium Hydroxide: 25%
- EVA Matrix: 50%
- Sauran Additives (masu hada biyu, filastikizers, da dai sauransu): 5%
