Aluminom Hypophosphite na-egbochi ire ọkụ na MCA maka tubing na-ekpo ọkụ EVA

Mgbe ị na-eji aluminom hypophosphite, MCA (melamine cyanurate), na magnesium hydroxide dị ka ọkụ retardants na Eva okpomọkụ-shrink tubing, akwadoro usoro onunu ogwu na njikarịcha ntụziaka bụ ndị a:

1. Na-atụ aro usoro onunu ọkụ retardants

Aluminom hypophosphite

Usoro onunu ogwu:5%-10%
Ọrụ:Ọkụ na-egbochi ire ọkụ nke ukwuu, na-akwalite mmepụta cha cha, ma na-ebelata ọnụego mwepụta okpomọkụ.
Mara:Oke oke nwere ike mebie mgbanwe ihe onwunwe; Ekwesịrị itinye ndị ọrụ synergistic maka nkwalite.

MCA (Melamine Cyanurate)

Usoro onunu ogwu:10%-15%
Ọrụ:Ọkụ na-egbochi ọkụ na-adọba gas, na-amịkọrọ okpomọkụ ma wepụta gas ndị na-adịghị arụ ọrụ (dịka ọmụmaatụ, NH₃), na-emekọrịta ihe na aluminom hypophosphite iji kwalite ire ọkụ.
Mara:Ibubiga ibu nwere ike ibute mbugharị; Ekwesịrị ijide n'aka na ndakọrịta na EVA.

Magnesium Hydroxide (Mg(OH)₂)

Usoro onunu ogwu:20%-30%
Ọrụ:Endothermic ire ere na-ewepụta uzuoku mmiri, na-agbaze gas na-ere ọkụ ma na-egbochi anwụrụ ọkụ.
Mara:Ịkwado dị elu nwere ike ibelata ihe eji arụ ọrụ; A na-atụ aro mgbanwe n'elu iji meziwanye mgbasa.

2. Ntụnye nkwalite nhazi nhazi

Sistemu na-egbochi ire ọkụ:Ekwesighi ịfefe 50% iji doziwanye ogologo oge ire ọkụ na nhazi (dịka ọmụmaatụ, mgbanwe, ọnụego mbelata).
Mmetụta mmekọrịta
Aluminom hypophosphite na MCA nwere ike ibelata doses onye ọ bụla (dịka ọmụmaatụ, 8% aluminom hypophosphite + 12% MCA).
Magnesium hydroxide na-emeju ire ere site na mmetụta endothermic mgbe ọ na-ebelata anwụrụ ọkụ.
Ọgwụgwọ elu:Ngwakọta ndị na-ejikọta Silane nwere ike ịkwalite mgbasasa na njikọta ihu nke magnesium hydroxide.
Ihe mgbakwunye inyeaka:
Tinye 2%-5% ndị na-emepụta cha cha (dịka ọmụmaatụ, pentaerythritol) iji kwalite nkwụsi ike nke oyi akwa char.
Tinye obere ihe ndị na-emepụta plastik (dịka ọmụmaatụ, mmanụ soybean epoxidized) iji kwụọ ụgwọ maka mfu mgbanwe.

3. Ntuziaka nkwado arụmọrụ

Nnwale ọgbaghara ire ọkụ:
Nnwale ọkụ kwụ ọtọ UL94 (ebumnobi: V-0).
Ndepụta Oxygen na-egbochi (LOI>28%).
Ngwongwo igwe:
Nyochaa ike tensile na elongation na nkwụsịtụ iji hụ na mgbanwe na-emezu ngwa ngwa.
Nhazi:
Nyochaa Ndekọ Flow Melt (MFI) ka ịzenarị ihe isi ike nhazi n'ihi oke njuju.

4. Ọnụ na ihe gbasara gburugburu ebe obibi

Ntụle ọnụ ahịa:Aluminom hypophosphite dị oke ọnụ; Enwere ike ibelata usoro onunu ogwu ya (tinyere MCA) iji chịkwaa ọnụ ahịa.
Enyi na gburugburu ebe obibi:Magnesium hydroxide adịghị egbu egbu ma na-egbochi anwụrụ ọkụ, na-eme ka ọ dị mma maka ngwa enyi na enyi.

Ụdị ihe atụ (maka naanị ntụaka):
