Yadda ake yin soso mai latex mai hana harshen wuta?

Don buƙatun mai hana harshen wuta na soso mai latex, ga abin da ke tafe nan: Bincike kan wasu masu hana harshen wuta da ake da su (aluminum hydroxide, zinc borate, aluminum hypophosphite, MCA) tare da shawarwarin tsari:

I. Binciken Aiwatar da Maganin Da Ke Hana Wuta

Aluminum Hydroxide (ATH)
Fa'idodi:

• Yana da sauƙin amfani da muhalli, kuma yana da ƙarancin kuɗi.
• Yana aiki ta hanyar rugujewar endothermic da kuma fitar da tururin ruwa, wanda ya dace da tsarin da ba shi da halogen.

Rashin amfani:

• Yana buƙatar ɗaukar kaya mai yawa (30-50 phr) don inganci, wanda zai iya shafar sassauci da yawan soso.

Aiwatarwa:

• Ya dace da magungunan rage harshen wuta na asali.
• Ana ba da shawarar a haɗa shi da masu haɗin gwiwa (misali, zinc borate).

Zinc Borate
Fa'idodi:

• Maganin hana harshen wuta mai haɗin gwiwa, yana haɓaka tasirin ATH.
• Yana haɓaka samuwar ƙwaya kuma yana hana hayaƙi.

Rashin amfani:

• Inganci mai iyaka idan aka yi amfani da shi kaɗai; yana buƙatar haɗuwa da sauran abubuwan hana wuta.

Aiwatarwa:

• Ana ba da shawarar a matsayin mai haɗin gwiwa ga ATH ko aluminum hypophosphite.

Aluminum Hypophosphite
Fa'idodi:

• Inganci sosai, babu halogen, ƙarancin lodawa (10-20 hr).
• Kyakkyawan kwanciyar hankali na zafi, wanda ya dace da buƙatun rage wutar wuta mai yawa.

Rashin amfani:

• Mafi tsada.
• Yana buƙatar tabbatar da daidaito da tsarin latex.

Aiwatarwa:

• Ya dace da ƙa'idodin rage yawan harshen wuta (misali, UL94 V-0).
• Ana iya amfani da shi shi kaɗai ko kuma a haɗa shi.

MCA (Melamine Cyanurate)
Fa'idodi:

• Maganin hana harshen wuta da ke ɗauke da sinadarin nitrogen, wanda ke hana hayaki.

Rashin amfani:

• Rashin watsuwa mara kyau.
• Zai iya tsoma baki wajen kumfa.
• Babban zafin ruɓewa (~300°C), bai dace da aikin latex mai ƙarancin zafi ba.

Aiwatarwa:

• Ba a ba da shawarar a matsayin fifiko ba; yana buƙatar tabbatar da gwaji.

II. Shawarwari kan Tsarukan da Shawarwari kan Tsarin Aiki

Tsarin 1: ATH + Zinc Borate (Zaɓin Tattalin Arziki)
Abun da aka haɗa:

• Aluminum Hydroxide (ATH): 30-40 hr
• Zinc Borate: 5-10 hr
• Mai watsawa (misali, wakilin haɗa silane): 1-2 phr (yana inganta warwatsewa)

Halaye:

• Mai rahusa, mai kyau ga muhalli.
• Ya dace da buƙatun hana harshen wuta gabaɗaya (misali, UL94 HF-1).
• Zai iya rage juriyar soso kaɗan; Ana buƙatar inganta Vulcanization.

Tsarin 2: Aluminum Hypophosphite + Zinc Borate (Zaɓin Ingantaccen Aiki)
Abun da aka haɗa:

• Aluminum Hypophosphite: 15-20 hr
• Zinc Borate: 5-8 hr
• Mai amfani da filastik (misali, paraffin mai ruwa): 2-3 phr (yana inganta iya sarrafawa)

Halaye:

• Ingantaccen aikin rage wutar lantarki, ƙarancin lodi.
• Ya dace da yanayi mai yawan buƙata (misali, ƙonewa a tsaye V-0).
• Dacewar aluminum hypophosphite da latex yana buƙatar gwaji.

Tsarin 3: ATH + Aluminum Hypophosphite (Zaɓin da ya dace)
Abun da aka haɗa:

• Aluminum Hydroxide: 20-30 hr
• Aluminum Hypophosphite: 10-15 hr
• Zinc Borate: 3-5 hr

Halaye:

• Yana daidaita farashi da aiki.
• Yana rage dogaro da na'urar hana harshen wuta guda ɗaya, yana rage tasirin da ke kan halayen jiki.

III. La'akari da Tsarin Aiki

Watsawa:

• Ya kamata a niƙa masu hana harshen wuta zuwa ≤5μm domin guje wa shafar tsarin kumfa.
• Ana ba da shawarar a yi amfani da kayan haɗin latex ko na'urar haɗawa mai sauri kafin a fara amfani da shi.

Yanayin Warkewa:

• A kula da zafin jiki (yawanci 110-130°C don latex) don hana ruɓewar abubuwan hana harshen wuta da wuri.

Gwajin Aiki:

• Gwaje-gwaje masu mahimmanci: Ma'aunin Iskar Oxygen (LOI), Ƙonewa a Tsaye (UL94), Yawan Kauri, Juriya.
• Idan ƙarfin hana harshen wuta bai isa ba, a hankali ƙara yawan aluminum hypophosphite ko ATH.

IV. Ƙarin Shawarwari

Gwajin MCA:

• Idan ana gwadawa, yi amfani da 5-10 hr a cikin ƙananan rukuni don ganin tasirin da ke kan daidaiton kumfa.

Takaddun Shaidar Muhalli:

• Tabbatar da cewa an zaɓi na'urorin hana harshen wuta da aka yi amfani da su wajen fitar da kayayyaki zuwa ƙasashen waje bisa ga umarnin RoHS/REACH.

Haɗaɗɗun Haɗaɗɗun Haɗaɗɗu:

• Yi la'akari da ƙara ƙaramin adadin nanoclay (2-3 phr) don haɓaka tasirin shingen char.
