Na'urar retardant na magana don adhesives

Ƙirar ƙira ta harshen wuta don mannewa yana buƙatar gyare-gyare bisa ga nau'in kayan tushe na manne (kamar resin epoxy, polyurethane, acrylic, da sauransu) da yanayin aikace-aikacen (kamar gini, lantarki, mota, da sauransu). A ƙasa akwai abubuwan haɗin ginin harshen wuta gama gari da ayyukansu, waɗanda ke rufe duka halogenated da mafita mai hana halogen.

1. Ƙa'idodin Ƙirƙirar Ƙirƙirar Harshen Harshen Harshe

• Babban inganciHaɗu da UL 94 V0 ko V2.
• Daidaituwa: Ya kamata mai ɗaukar harshen wuta ya dace da kayan tushe mai mannewa ba tare da shafar aikin haɗin gwiwa ba.
• Abokan Muhalli: Ba da fifiko ga masu kare harshen wuta marasa halogen don biyan ka'idojin muhalli.
• Yin aiki: Kada mai ɗaukar harshen wuta ya tsoma baki tare da tsarin warkewar manne ko iya gudana.

2. Halogenated Flame Retardant Adhesive Formulation

Halogenated harshen retardants (misali, brominated) yana katse amsawar sarkar konewa ta hanyar sakin halogen radicals, yana ba da ingantaccen ingantaccen ci gaba.

Abubuwan Haɓakawa:

• Material Base Na Adhesive: Epoxy resin, polyurethane, ko acrylic.
• Brominated Flame Retardant: 10-20% (misali, decabromodiphenyl ether, brominated polystyrene).
• Antimony Trioxide (Synergist): 3-5% (yana haɓaka tasirin wuta).
• Filastik: 1-3% (yana inganta sassauci).
• Wakilin Magani: Zaɓi bisa nau'in mannewa (misali, tushen amine don resin epoxy).
• Mai narkewa: Kamar yadda ake buƙata (yana daidaita danko).

Halaye:

• Amfani: High harshen retardant yadda ya dace, low ƙara adadin.
• Rashin amfani: Zai iya haifar da iskar gas mai guba yayin konewa; matsalolin muhalli.

3. Halogen-Free Flame Retardant Adhesive Formulation

Masu kare harshen wuta marasa halogen (misali, tushen phosphorus, tushen nitrogen, ko inorganic hydroxides) suna aiki ta hanyar halayen endothermic ko samuwar Layer na kariya, suna ba da ingantaccen aikin muhalli.

Abubuwan Haɓakawa:

• Material Base Na Adhesive: Epoxy resin, polyurethane, ko acrylic.
• Tushen Harshen Harshen Fosfour: 10-15% (misali,ammonium polyphosphate APPko jan phosphorus).
• Tushen Harshen Nitrogen: 5-10% (misali, melamine cyanurate MCA).
• Inorganic Hydroxides: 20-30% (misali, aluminum hydroxide ko magnesium hydroxide).
• Filastik: 1-3% (yana inganta sassauci).
• Wakilin Magani: An zaɓa bisa nau'in mannewa.
• Mai narkewa: Kamar yadda ake buƙata (yana daidaita danko).

Halaye:

• Amfani: Abokan muhalli, babu hayaki mai guba, mai bin ka'idoji.
• Rashin amfani: Ƙarƙashin ƙarancin harshen wuta, mafi girman adadin ƙari, na iya rinjayar kaddarorin inji.

4. Mahimman ra'ayi a cikin Ƙirar Ƙira

• Zaɓin Ƙunƙarar Wuta:
  • Halogenated: Babban inganci amma yana haifar da haɗarin muhalli da lafiya.
  • Halogen-Free: Abokan mu'amala amma yana buƙatar adadi mai yawa.
• Daidaituwa: Tabbatar cewa mai ɗaukar harshen wuta baya haifar da lalata ko rage aikin haɗin gwiwa.
• Yin aiki: Guji tsangwama tare da waraka da gudana.
• Yarda da Muhalli: Fi son zaɓuka marasa halogen don saduwa da RoHS, REACH, da sauransu.

5. Aikace-aikace na yau da kullun

• Gina: Wuta mai jurewa sealants, tsarin adhesives.
• Kayan lantarki: Circuit board encapsulation adhesives, conductive adhesives.
• Motoci: Adhesives na fitillu, adhesives na ciki.

6. Shawarwari ingantawa Formulation

• Haɓaka Dagewar Wuta:
  • Haɗin haɗin gwiwa (misali, halogen-antimony, phosphorus-nitrogen).
  • Nano harshen retardants (misali, nano magnesium hydroxide ko nano lãka) don inganta inganci da rage ƙari adadin.
• Inganta Kayayyakin Injini:
  • Tougheners (misali, POE ko EPDM) don haɓaka sassauci da juriya mai tasiri.
  • Ƙarfafa filaye (misali, fiber gilashi) don ƙara ƙarfi da tsauri.
• Rage Kuɗi:
  • Haɓaka ƙimar jinkirin harshen wuta don rage yawan amfani yayin biyan buƙatu.
  • Zaɓi kayan aiki masu tsada (misali, na gida ko gaurayewar harshen wuta).

7. Bukatun Muhalli da Ka'idoji

• Halogenated Flame Retardants: Ƙuntatawa a ƙarƙashin RoHS, REACH, da dai sauransu; yi amfani da hankali.
• Halogen-Free Flame Retardants: Mai yarda da ka'idoji; yanayin gaba.

8. Takaitawa

Ya kamata a ƙirƙira ƙirar ƙirar wuta mai mannewa bisa ƙayyadaddun aikace-aikace da buƙatun tsari, zaɓi tsakanin zaɓin halogenated ko mara halogen. Halogenated harshen retardants yana ba da ingantaccen inganci amma yana haifar da haɗarin muhalli, yayin da hanyoyin da ba su da halogen suna da aminci ga yanayin yanayi amma suna buƙatar ƙarin ƙari. Ta hanyar inganta ƙirar ƙira da matakai, za a iya haɓaka aiki mai girma, abokantaka da muhalli, da ƙudi mai kashe wuta mai tsada don gine-gine, kayan lantarki, motoci, da sauran masana'antu.
