Aluminom Hypophosphite na MCA nke na-egbochi ire ọkụ maka EVA Heat-Shrink Tubing

Aluminom Hypophosphite na MCA nke na-egbochi ire ọkụ maka EVA Heat-Shrink Tubing

Mgbe ị na-eji aluminum hypophosphite, MCA (melamine cyanurate), na magnesium hydroxide dị ka ihe na-egbochi ire ọkụ na ọkpọkọ okpomọkụ EVA, usoro onunu ogwu akwadoro na ntuziaka nhazi bụ ndị a:

1. Usoro akwadoro maka ihe ndị na-egbochi ire ọkụ

Aluminom Hypophosphite

• Ọnụọgụ ọgwụ:5%–10%
• Ọrụ:Ihe na-egbochi ire ọkụ nke ọma, na-akwalite mmepụta ike, ma na-ebelata ọnụego mwepụta okpomọkụ.
• Rịba ama:Oke oke nwere ike imebi mgbanwe ihe; a ga-etinye ihe ndị na-eme ka ihe dị n'otu maka imeziwanye ya.

MCA (Melamine Cyanurate)

• Ọnụọgụ ọgwụ:10%–15%
• Ọrụ:Ihe na-egbochi ire ọkụ nke gas, na-amịkọrọ okpomọkụ ma na-ewepụta gas ndị na-adịghị arụ ọrụ (dịka ọmụmaatụ, NH₃), na-ejikọta ya na aluminom hypophosphite iji mee ka ire ọkụ dịkwuo mma.
• Rịba ama:Ibu oke ibu nwere ike ibute mbugharị; a ga-ahụrịrị na enwere ike ijikọ ya na EVA.

Magnesium Hydroxide (Mg(OH)₂)

• Ọnụọgụ ọgwụ:20%–30%
• Ọrụ:Njehie nke endothermic na-ewepụta uzuoku mmiri, na-agbaze gas ndị na-ere ọkụ ma na-egbochi anwụrụ ọkụ.
• Rịba ama:Ibu ibu dị elu nwere ike ibelata ihe onwunwe igwe; a na-atụ aro ka a gbanwee elu iji melite mgbasa.

2. Ndụmọdụ maka Nhazi Nhazi

• Sistemụ Nkwụsị Ọkụ Nile:Ekwesighi ịgafe 50% iji dozie nkwụsịtụ ire ọkụ na nhazi (dịka ọmụmaatụ, mgbanwe, ọnụego mbelata).
• Mmetụta Mmekọrịta:
• Aluminom hypophosphite na MCA nwere ike ibelata ọnụọgụ nke otu onye (dịka ọmụmaatụ, 8% aluminom hypophosphite + 12% MCA).
• Magnesium hydroxide na-eme ka ire ọkụ ghara ịdị irè site na mmetụta endothermic ma na-ebelata anwụrụ ọkụ.
• Ọgwụgwọ Elu:Ihe ndị na-ejikọ Silane nwere ike ime ka mgbasa na njikọ dị n'etiti magnesium hydroxide dịkwuo mma.
• Ihe mgbakwunye enyemaka:
• Tinye ihe ndị na-emepụta char-forming 2%–5% (dịka ọmụmaatụ, pentaerythritol) iji melite iguzosi ike n'ezi ihe nke char oyi akwa.
• Tinye obere ihe ndị na-eme ka plastik dị nro (dịka ọmụmaatụ, mmanụ soybean a gwakọtara agwakọta) iji kwụọ ụgwọ maka mgbanwe ọ bụla.

3. Ntuziaka maka Nnwale Arụmọrụ

• Nnwale Nkwụsị Ọkụ:
• Nnwale ọkụ kwụ ọtọ nke UL94 (ihe mgbaru ọsọ: V-0).
• Ịmachi Ndekọ Oxygen (LOI > 28%).
• Njirimara Mechanical:
• Nyochaa ike nrụgide na ogologo oge mgbe ezumike gasịrị iji hụ na mgbanwe na-emezu ihe achọrọ maka ngwa.
• Nhazi:
• Nyochaa Melt Flow Index (MFI) iji zere nsogbu nhazi n'ihi oke ihe e ji emeju ihe.

4. Ọnụ ego na ihe gbasara gburugburu ebe obibi

• Nhazi Ọnụ Ego:Aluminom hypophosphite dị oke ọnụ; enwere ike ibelata dose ya (gbakwunyere na MCA) iji chịkwaa ọnụ ahịa.
• Enyi na Enyi Gburugburu Ebe Obibi:Magnesium hydroxide anaghị egbu egbu ma na-egbochi anwụrụ ọkụ, nke na-eme ka ọ dị mma maka iji ya eme ihe n'ebe obibi.

Nhazi Ihe Nlereanya (maka ntụaka naanị):

• Aluminom Hypophosphite: 8%
• MCA: 12%
• Magnesium Haịdroksidọk: 25%
• Matriks EVA: 50%
• Ihe mgbakwunye ndị ọzọ (ihe ndị na-ejikọ ọnụ, ihe ndị na-eme ka plastik sie ike, wdg): 5%
