Ngwọta ihe mgbochi ọkụ maka thermoplastic elastomer TPE

Mgbe ị na-eji aluminum hypophosphite (AHP) na melamine cyanurate (MCA) na thermoplastic elastomers (TPE) iji nweta ọkwa UL94 V0 nke na-egbochi ire ọkụ, ọ dị mkpa ịtụle usoro na-egbochi ire ọkụ, ndakọrịta ihe, na ọnọdụ nhazi. N'okpuru ebe a bụ usoro akwadoro:

1. Ibu Ibu A Na-ejikarị Eme Ihe n'otu n'otu

Aluminom Hypophosphite (AHP)

• Na-ebu: 15-25%
• Àgwà: Ọ na-akwalite mmepụta char, nke dabara adaba maka sistemụ chọrọ arụmọrụ igwe dị elu, mana a ga-achịkwa okpomọkụ nhazi (a na-atụ aro ya ≤240°C).

Melamine Cyanurate (MCA)

• Na-ebu: 25-35%
• Àgwà: Ọ dabere na mmebi endothermic na mmịpụta gas; nnukwu ibu nwere ike ibelata mgbanwe ihe.

2. Usoro Ngwakọta Njikọta A Na-atụ aro

Oke Ngwakọta AHP na MCA

• AHP: 10-15%
• MCA: 10-20%
• Ngụkọta ibu: 20-30%

Uru: Mmetụta synergistic na-ebelata ibu zuru oke ebe ọ na-ebelata mmetụta na ihe onwunwe igwe (dịka ọmụmaatụ, ike nrụgide, mgbanwe).

3. Isi Ihe Ndị Na-emetụta Ya

• Ụdị Ihe Ntọala: TPE ndị dabere na SEBS na-adịkarị mfe iwepụ karịa ndị dabere na SBS, na-enye ohere maka obere ibu mgbakwunye.
• Ọkpụrụkpụ ihe nlele: Nrubeisi UL94 V0 na-enwe mmetụta dị ukwuu na ọkpụrụkpụ (1.6mm siri ike karịa 3.2mm), yabụ a ga-agbanwerịrị usoro nhazi dịka o kwesịrị.
• Ndị na-eme mmekọrịta: Itinye ụrọ nano-clay ma ọ bụ talc 2-5% nwere ike ime ka nhazi char dịkwuo mma ma belata ibu nke na-egbochi ire ọkụ.
• Okpomọkụ nhazi: Hụ na okpomọkụ nhazi dị n'okpuru ebe ire ere nke AHP (≤240°C) na MCA (≤300°C).

4. Usoro Nkwenye Akwadoro

• Ule Mmalite: Mee obere nnwale site na iji AHP 12% + MCA 15% (ngụkọta 27%).
• Nnwale Arụmọrụ: Nyochaa mbelata ire ọkụ (UL94 ọkụ kwụ ọtọ), ike siri ike (Shore A), ike nrụgide, na ndeksi mmiri ịgbaze.
• NhaziỌ bụrụ na mmiri na-ata, mụbaa oke AHP (iji mee ka ọkụ dịkwuo elu); ọ bụrụ na ihe ndị dị n'ime igwe adịghị mma, tụlee itinye ihe ndị na-eme ka plastik dị nro ma ọ bụ belata ibu zuru oke.

5. Ihe Ndị A Ga-akpachara Anya

• Zere ijikọta ya na ihe ndị na-eme ka ihe dị n'ime acidic (dịka ọmụmaatụ, ụfọdụ ihe na-agba agba), n'ihi na ha nwere ike imebi AHP.
• Ọ bụrụ na TPE nwere nnukwu ihe eji eme ka ihe dị n'ime mmanụ, ọ ga-adị mkpa ka e mee ka ibu ihe na-eme ka ihe dị n'ọkụ ghara ịdị irè (mmanụ nwere ike ibelata arụmọrụ nke ihe na-eme ka ọkụ ghara ịdị irè).

Site na ngwakọta ezi uche dị na ya na nhazi nnwale, enwere ike nweta nrubeisi UL94 V0 ma na-ahazi nhazi TPE na arụmọrụ igwe. A na-atụ aro ka a na-arụkọ ọrụ na ndị na-ebubata ihe na-egbochi ire ọkụ maka ngwọta ahaziri ahazi.
