Mai hana harshen wuta Aluminum Hypophosphite da MCA don bututun rage zafi na EVA

Lokacin amfani da aluminum hypophosphite, MCA (melamine cyanurate), da magnesium hydroxide azaman masu hana harshen wuta a cikin bututun rage zafi na EVA, adadin da aka ba da shawarar da kuma umarnin ingantawa sune kamar haka:

1. Shawarar Yawan Maganin Da Ke Hana Wuta

Aluminum Hypophosphite

• Yawan amfani:5%–10%
• Aiki:Mai hana harshen wuta sosai, yana haɓaka samuwar char, kuma yana rage saurin fitar da zafi.
• Lura:Yawan da ya wuce kima na iya kawo cikas ga sassaucin kayan aiki; ya kamata a haɗa sinadaran haɗin gwiwa don ingantawa.

MCA (Melamine Cyanurate)

• Yawan amfani:10%–15%
• Aiki:Mai hana harshen wuta a lokacin iskar gas, yana shan zafi kuma yana fitar da iskar gas mara aiki (misali, NH₃), yana haɗa kai da aluminum hypophosphite don haɓaka jinkirin harshen wuta.
• Lura:Yawan kaya na iya haifar da ƙaura; dole ne a tabbatar da dacewa da EVA.

Magnesium Hydroxide (Mg(OH)₂)

• Yawan amfani:20%–30%
• Aiki:Rushewar endothermic yana fitar da tururin ruwa, yana narkar da iskar gas mai kama da wuta da kuma rage hayaki.
• Lura:Yawan lodi na iya rage halayen injina; ana ba da shawarar gyaran saman don inganta watsawa.

2. Shawarwari Kan Inganta Tsarin

• Tsarin Jumlar Hana Wuta:Bai kamata ya wuce kashi 50% ba don daidaita jinkirin harshen wuta da kuma iya sarrafawa (misali, sassauci, ƙimar raguwa).
• Tasirin Haɗin gwiwa:
• Aluminum hypophosphite da MCA na iya rage yawan shan magani (misali, 8% aluminum hypophosphite + 12% MCA).
• Magnesium hydroxide yana ƙara juriyar harshen wuta ta hanyar tasirin endothermic yayin da yake rage hayaki.
• Maganin Fuskar:Sinadaran haɗin Silane na iya haɓaka watsawa da haɗin kai tsakanin magnesium hydroxide.
• Ƙarin Abinci:
• Ƙara 2%–5% na sinadaran da ke samar da char (misali, pentaerythritol) don inganta daidaiton layin char.
• A haɗa ƙananan adadin robobi (misali, man waken soya da aka yi amfani da shi wajen yin amfani da epoxidized) don rama asarar sassauci.

3. Umarnin Tabbatar da Aiki

• Gwajin Jinkirin Wuta:
• Gwajin ƙonawa na tsaye na UL94 (maƙasudi: V-0).
• Iyakance Ma'aunin Iskar Oxygen (LOI >28%).
• Kayayyakin Inji:
• Kimanta ƙarfin juriya da tsayin daka a lokacin hutu don tabbatar da sassauci ya cika buƙatun aikace-aikacen.
• Tsarin sarrafawa:
• Kula da Ma'aunin Gudun Narkewa (MFI) don guje wa matsalolin sarrafawa saboda yawan cikawa.

4. La'akari da Kuɗi da Muhalli

• Daidaiton Kuɗi:Aluminum hypophosphite yana da tsada sosai; ana iya rage yawan maganinsa (an ƙara masa MCA) don sarrafa farashi.
• Kyakkyawan Muhalli:Magnesium hydroxide ba shi da guba kuma yana hana hayaki, wanda hakan ya sa ya dace da amfani da shi don muhalli.

Misali Tsarin (don tunani kawai):

• Aluminum Hypophosphite: 8%
• MCA: 12%
• Magnesium Hydroxide: 25%
• Matrix na EVA: 50%
• Sauran Ƙarin Abinci (masu haɗa sinadarai, masu amfani da filastik, da sauransu): 5%
