Usoro ntụaka nke PBT nke na-anaghị agba ọkụ nke na-anaghị agba ọkụ

Iji mee ka usoro nke ihe mgbochi ọkụ na-enweghị halogen maka PBT dịkwuo mma, ọ dị mkpa ịhazi arụmọrụ nke ihe mgbochi ọkụ, nkwụsi ike okpomọkụ, ndakọrịta okpomọkụ nhazi, na njirimara igwe. N'okpuru ebe a bụ atụmatụ njikọta kachasị mma yana nyocha dị mkpa:

1. Nchikota ihe mgbochi ọkụ nke isi

Nhọrọ nke 1: Aluminum Hypophosphite + MCA (Melamine Cyanurate) + Zinc Borate

Usoro:

Aluminom Hypophosphite (Nkwụsi ike okpomọkụ > 300°C): Na-akwalite nhazi ike n'oge a na-akpọchi akpọchi ma na-ewepụta radicals PO· n'oge gas iji kwụsị mmeghachi omume nke usoro ọkụ.
MCA (Mbibi na ~300°C): Mbibi nke endothermic na-ewepụta gas ndị na-adịghị arụ ọrụ (NH₃, H₂O), na-agbaze gas ndị na-ere ọkụ ma na-egbochi mmiri na-agbaze.
Zinc Borate (Ọgwụ gbawara agbawa > 300°C): Na-eme ka mmepụta iko dị ka ihe na-enwu enwu, na-ebelata anwụrụ ọkụ na ìhè anyanwụ mgbe ọ gasịrị.

Oke akwadoro:

Aluminom Hypophosphite (10-15%) + MCA (5-8%) + Zinc Borate (3-5%).

Nhọrọ nke 2: Magnesium Hydroxide nke a gbanwere n'elu + Aluminom Hypophosphite + Organic Phosphinate (dịka ọmụmaatụ, ADP)

Usoro:

Magnesium Hydroxide Emegharịrị (Mbibi ~ 300°C): Ọgwụgwọ elu (silane/titanate) na-eme ka mgbasa na nkwụsi ike okpomọkụ ka mma; oyi endothermic na-ebelata okpomọkụ ihe.
Phosphinate Organic (dịka ọmụmaatụ, ADP, nkwụsi ike okpomọkụ > 300°C): Ihe na-egbochi ọkụ gas nke ọma, na-ejikọta ya na sistemụ phosphorus-nitrogen.

Oke akwadoro:

Magnesium Hydroxide (15-20%) + Aluminom Hypophosphite (8-12%) + ADP (5-8%).

2. Ndị na-eme ihe n'otu oge (Synergists)

Nano-clay/Talc (2-3%): Na-eme ka mma nke char na njirimara igwe dịkwuo mma ma na-ebelata ibu nke ihe na-egbochi ire ọkụ.
PTFE (0.2-0.5%): Ihe na-egbochi ntapụ mmiri iji gbochie ntapụ mmiri ọkụ.
Ntụ ntụ Silicone (2-4%): Na-akwalite ọdịdị dị oke njọ, na-eme ka ire ọkụ na-adịghị mma ma na-egbuke egbuke elu.

3. Nchikota Ndị A Ga-ezere

Aluminom Hydroxide: Na-agbaze na 180-200°C (n'okpuru okpomọkụ nhazi PBT nke 220-250°C), na-eduga na mmebi tupu oge eruo.
Magnesium Hydroxide A Na-agbanweghị: Ọ chọrọ ọgwụgwọ elu iji gbochie nchikọta na mmebi okpomọkụ n'oge nhazi.

4. Ndụmọdụ Maka Mmezi Arụmọrụ

Ọgwụgwọ Elu: Jiri ihe njikọta silane na Mg(OH)₂ na zinc borate mee ka mgbasa na njikọ ihu dịkwuo mma.
Njikwa Okpomọkụ Nhazi: Hụ na okpomọkụ ire ere nke na-egbochi ire ọkụ karịrị 250°C iji zere ire ere.
Nhazi nke ihe onwunwe mekaniki: Jiri ihe nano-fillers (dịka ọmụmaatụ, SiO₂) ma ọ bụ ihe siri ike (dịka ọmụmaatụ, POE-g-MAH) kwụọ ụgwọ maka mfu ike.
