Itọkasi ina retardant agbekalẹ fun adhesives

Apẹrẹ idapada ina fun adhesives nilo lati ṣe adani da lori iru ohun elo ipilẹ alemora (gẹgẹbi resini epoxy, polyurethane, acrylic, bbl) ati awọn oju iṣẹlẹ ohun elo (gẹgẹbi ikole, ẹrọ itanna, adaṣe, ati bẹbẹ lọ). Ni isalẹ wa awọn ohun elo idapada ina alemora ti o wọpọ ati awọn iṣẹ wọn, ni wiwa mejeeji halogenated ati awọn solusan idaduro ina-ọfẹ halogen.

1. Awọn ilana ti Adhesive Flame Retardant Formulation Design

• Ṣiṣe giga: Pade UL 94 V0 tabi V2.
• Ibamu: Idaduro ina yẹ ki o wa ni ibamu pẹlu awọn ohun elo ipilẹ alamọra lai ni ipa lori iṣẹ ifunmọ.
• Ayika Friendliness: Ṣe pataki awọn idapada ina ti ko ni halogen lati ni ibamu pẹlu awọn ilana ayika.
• Ilana ṣiṣe: Awọn ina retardant ko yẹ ki o dabaru pẹlu awọn alemora ká curing ilana tabi sisan.

2. Halogenated Flame Retardant Adhesive Formulation

Awọn idaduro ina halogenated (fun apẹẹrẹ, brominated) da idalọwọduro idawọle pq ijona silẹ nipa jijade awọn ipilẹṣẹ halogen, fifun ṣiṣe imuduro ina giga.

Awọn irinše agbekalẹ:

• Alemora Mimọ elo: epoxy resini, polyurethane, tabi akiriliki.
• Brominated Flame Retardant: 10-20% (fun apẹẹrẹ, decabromodiphenyl ether, polystyrene brominated).
• Antimony Trioxide (Synergist): 3-5% (ṣe imudara ipa idaduro ina).
• Plasticizer: 1-3% (ṣe imudara ni irọrun).
• Curing Aṣoju: Ti yan da lori iru alemora (fun apẹẹrẹ, orisun amine fun resini iposii).
• Yiyan: Bi o ṣe nilo (ṣe atunṣe iki).

Awọn abuda:

• Awọn anfani: Ga ina retardant ṣiṣe, kekere aropin iye.
• Awọn alailanfani: Le ṣe awọn gaasi oloro nigba ijona; ayika awọn ifiyesi.

3. Halogen-Free Flame Retardant alemora Formulation

Awọn idaduro ina ti ko ni halogen (fun apẹẹrẹ, orisun irawọ owurọ, orisun nitrogen, tabi hydroxides inorganic) ṣiṣẹ nipasẹ awọn aati endothermic tabi dida Layer aabo, nfunni ni iṣẹ ṣiṣe ayika to dara julọ.

Awọn irinše agbekalẹ:

• Alemora Mimọ elo: epoxy resini, polyurethane, tabi akiriliki.
• Idaduro Ina-orisun irawọ owurọ: 10–15% (fun apẹẹrẹ,ammonium polyphosphate APPtabi irawọ owurọ pupa).
• Idaduro Ina orisun Nitrogen: 5–10% (fun apẹẹrẹ, melamine cyanurate MCA).
• Awọn hydroxides ti ko ni nkan: 20–30% (fun apẹẹrẹ, aluminiomu hydroxide tabi magnẹsia hydroxide).
• Plasticizer: 1-3% (ṣe imudara ni irọrun).
• Curing Aṣoju: Ti yan da lori iru alemora.
• Yiyan: Bi o ṣe nilo (ṣe atunṣe iki).

Awọn abuda:

• Awọn anfani: Ore ayika, ko si awọn itujade gaasi majele, ni ibamu pẹlu awọn ilana.
• Awọn alailanfani: Isalẹ ina retardant ṣiṣe, ti o ga afikun iye, le ni ipa lori darí-ini.

4. Key riro ni Formulation Design

• Ina Retardant Yiyan:
  • Halogenated: Ṣiṣe giga ṣugbọn o fa awọn eewu ayika ati ilera.
  • Halogen-ọfẹ: Eco-ore ṣugbọn nilo awọn iwọn nla.
• Ibamu: Rii daju pe ina retardant ko fa delamination tabi din iṣẹ imora.
• Ilana ṣiṣe: Yago fun kikọlu pẹlu curing ati flowability.
• Ibamu AyikaFẹ awọn aṣayan ti ko ni halogen lati pade RoHS, REACH, ati bẹbẹ lọ.

5. Aṣoju Awọn ohun elo

• Ikole: Fire-sooro sealants, igbekale adhesives.
• Awọn ẹrọ itanna: Circuit ọkọ encapsulation adhesives, conductive adhesives.
• Ọkọ ayọkẹlẹ: Awọn adhesives ori ina, awọn adhesives inu.

6. Awọn iṣeduro Iṣatunṣe Iṣaṣeṣe

• Imudara Idaduro Ina:
  • Awọn akojọpọ amuṣiṣẹpọ (fun apẹẹrẹ, halogen-antimony, irawọ owurọ-nitrogen).
  • Nano ina retardants (fun apẹẹrẹ, nano magnẹsia hydroxide tabi nano amo) lati mu ilọsiwaju ṣiṣẹ ati dinku awọn iye afikun.
• Imudara Mechanical Properties:
  • Tougheners (fun apẹẹrẹ, POE tabi EPDM) lati jẹki irọrun ati ipadabọ ipa.
  • Awọn ohun elo imudara (fun apẹẹrẹ, okun gilasi) lati mu agbara pọ si ati rigidity.
• Idinku iye owo:
  • Ṣe ilọsiwaju awọn iwọn idaduro ina lati dinku lilo lakoko awọn ibeere ipade.
  • Yan awọn ohun elo ti o ni iye owo (fun apẹẹrẹ, ile tabi awọn idaduro ina ti o dapọ).

7. Awọn ibeere Ayika ati Ilana

• Halogenated Flame Retardants: Ni ihamọ labẹ RoHS, REACH, ati bẹbẹ lọ; lo ṣọra.
• Halogen-Free Ina Retardants: Ni ibamu pẹlu awọn ilana; ojo iwaju aṣa.

8. Akopọ

Awọn agbekalẹ idapada ina alemora yẹ ki o jẹ apẹrẹ ti o da lori awọn ohun elo kan pato ati awọn ibeere ilana, yiyan laarin awọn aṣayan halogenated tabi halogen-free. Awọn idaduro ina halogenated nfunni ni ṣiṣe giga ṣugbọn ṣe awọn eewu ayika, lakoko ti awọn omiiran ti ko ni halogen jẹ ọrẹ-aye ṣugbọn nilo awọn oye afikun ti o ga julọ. Nipa iṣapeye awọn agbekalẹ ati awọn ilana, iṣẹ-giga, ore ayika, ati awọn adhesives imuduro ina ti o munadoko le jẹ idagbasoke fun ikole, ẹrọ itanna, adaṣe, ati awọn ile-iṣẹ miiran.
