Zinc Borate
Amfani:
- Ƙunƙarar harshen wuta na haɗin gwiwa, yana haɓaka tasirin ATH.
- Yana haɓaka samuwar char kuma yana hana hayaki.
Rashin hasara:
- Iyakar tasiri lokacin amfani da shi kadai; yana buƙatar haɗuwa tare da sauran masu kare wuta.
Aiwatar:
- An ba da shawarar azaman mai haɗin gwiwa don ATH ko aluminum hypophosphite.
Aluminum Hypophosphite
Amfani:
- Ingantacciyar inganci, mara halogen, ƙarancin kaya (10-20 phr).
- Kyakkyawan kwanciyar hankali na thermal, dace da buƙatun jinkirin harshen wuta.
Rashin hasara:
- Mafi girman farashi.
- Daidaitawa tare da tsarin latex yana buƙatar tabbaci.
Aiwatar:
- Ya dace da ma'aunin jinkirin harshen wuta (misali, UL94 V-0).
- Ana iya amfani da shi kadai ko a hade.
MCA (Melamine Cyanurate)
Amfani:
- Nitrogen tushen harshen wuta retardant, danne hayaki.
Rashin hasara:
- Rashin rarrabawa.
- Zai iya tsoma baki tare da kumfa.
- Babban bazuwar zafin jiki (~ 300°C), wanda bai dace ba tare da sarrafa latex mai ƙarancin zafin jiki.
Aiwatar:
- Ba a ba da shawarar a matsayin fifiko; yana buƙatar tabbatarwa na gwaji.
II. Shawarwari da Shawarwari da Shawarwari
Formulation 1: ATH + Zinc Borate (Zabin Tattalin Arziki)
Abun ciki:
- Aluminum Hydroxide (ATH): 30-40 phr
- Zinc Borate: 5-10 phr
- Watsewa (misali, wakilin haɗin gwiwar silane): 1-2 phr (yana haɓaka rarrabuwa)
Halaye:
- Low cost, m muhalli.
- Ya dace da buƙatun jinkirin harshen wuta (misali, UL94 HF-1).
- Zai iya ɗan rage ƙarfin soso; Ana buƙatar inganta haɓaka vulcanization.
Ƙirar 2: Aluminum Hypophosphite + Zinc Borate (Zaɓin Ƙarfin Ƙarfi)
Abun ciki:
- Aluminum Hypophosphite: 15-20 phr
- Zinc Borate: 5-8 phr
- Filastik (misali, paraffin ruwa): 2-3 phr (yana inganta iya aiki)
Halaye:
- Babban ƙarfin jinkirin harshen wuta, ƙarancin kaya.
- Ya dace da yanayin buƙatu mai girma (misali, kuna V-0 a tsaye).
- Daidaituwar aluminium hypophosphite tare da buƙatun gwaji na latex.
Tsarin 3: ATH + Aluminum Hypophosphite (Madaidaicin Zabin)
Abun ciki:
- Aluminum Hydroxide: 20-30 phr
- Aluminum Hypophosphite: 10-15 phr
- Zinc Borate: 3-5 phr
Halaye:
- Daidaita farashi da aiki.
- Yana rage dogaro ga mai riƙe harshen wuta guda ɗaya, yana rage tasiri akan kaddarorin jiki.
III. La'akarin Tsari
Watsewa:
- Yakamata a yi kasa mai riƙe da wuta zuwa ≤5μm don gujewa cutar da tsarin kumfa.
- Ana ba da shawarar watsawa a cikin latex ko kayan haɗawa mai sauri.
Yanayin Magani:
- Sarrafa zafin jiki na warkewa (yawanci 110-130 ° C don latex) don hana bazuwar zafin wuta da wuri.
Gwajin Aiki:
- Gwaje-gwaje masu mahimmanci: Oxygen Index (LOI), Ƙona a tsaye (UL94), Ƙwaƙwalwar Ƙarfafawa.
- Idan jinkirin harshen wuta bai isa ba, a hankali ƙara aluminium hypophosphite ko ƙimar ATH.
IV. Ƙarin Shawarwari
Gwajin MCA:
- Idan gwaji, yi amfani da 5-10 phr a cikin ƙananan batches don lura da tasiri akan daidaiton kumfa.
Takaddun shaida na Muhalli:
- Tabbatar da zaɓaɓɓen masu kare harshen wuta sun bi RoHS/REACH don fitarwa.
Haɗin Haɗin Kai:
- Yi la'akari da ƙara ƙananan adadin nanoclay (2-3 phr) don haɓaka tasirin shinge na char.
