Ngā otinga ārai mura mō te elastomer thermoplastic TPE

Ina whakamahia te konumohe hypophosphite (AHP) me te melamine cyanurate (MCA) i roto i ngā elastomers thermoplastic (TPE) hei whakatutuki i te whakatauranga ātete-mumura UL94 V0, he mea nui kia whakaarohia te tikanga ātete-mumura, te hototahitanga o ngā rauemi, me ngā tikanga tukatuka. Kei raro nei te whakatakotoranga kua tūtohutia:

1. Te Utaina Noa Ina Whakamahia Takitahi

Konumohe Hipofosita (AHP)

• Utaina: 15-25%
• Ngā Āhuatanga: Ka whakatairanga i te hanganga o te waro, he pai mō ngā pūnaha e hiahia ana ki te mahi miihini teitei, engari me whakahaere te pāmahana tukatuka (e taunakitia ana ≤240°C).

Melamine Cyanurate (MCA)

• Utaina: 25-35%
• Ngā Āhuatanga: E whakawhirinaki ana ki te pirau wera me te waimehatanga hau; ka whakaiti pea te taumahatanga o te rauemi i te ngāwari.

2. Te Tātai Whakaranu Hikoi e Manakohia ana

Te ōwehenga whakaranu AHP me te MCA

• Āhuatanga Taumaha: 10-15%
• MCA: 10-20%
• Te uta katoa: 20-30%

Ngā PaingaKa whakaitihia e te pānga mahi tahi te kawenga katoa, me te whakaiti i te pānga ki ngā āhuatanga ā-pūkaha (hei tauira, te kaha kume, te ngāwari).

3. Ngā Take Matua e Whakaaweawe Ana

• Momo Rauemi TurangaHe māmā ake te ārai i te mura o ngā TPE e hangai ana ki te SEBS i ngā mea e hangai ana ki te SBS, ā, he iti ake te utaina tāpiri.
• Matotoru TauiraHe mea aro ki te matotoru te tutuki i te UL94 V0 (he uaua ake te 1.6mm i te 3.2mm), nō reira me whakarerekē ngā whakatakotoranga kia rite.
• Ngā KaitautokoMā te tāpiri i te 2-5% nano-clay, te talc rānei, ka taea te whakapai ake i te hanganga waro me te whakaiti i te kawenga ātete mura.
• Te pāmahana tukatukaMe whakarite kia noho tonu ngā pāmahana tukatuka i raro i ngā pūwāhi pirau o te AHP (≤240°C) me te MCA (≤300°C).

4. Ngā Hipanga Manatoko i Manakohia

• Whakamātautau TuatahiWhakahaerehia ngā whakamātautau iti me te AHP 12% + MCA 15% (27% katoa).
• Whakamātautau MahiArotakehia te ātete mura (te mura poutū UL94), te pakeke (Tahataha A), te kaha kume, me te taupū rere rewa.
• ArotautangaMena ka maturuturu, whakanuia te ōwehenga AHP (hei whakanui ake i te weranga); mena he ngoikore ngā āhuatanga miihini, whakaarohia te tāpiri i ngā mea whakapūmau kirihou, te whakaiti rānei i te uta katoa.

5. Ngā Whakatūpato

• Kaua e whakaranua ki ngā whakakī waikawa (hei tauira, ētahi tae), nā te mea ka taea e rātou te whakararu i te AHP.
• Mena he nui ngā matū whakakirikiri hinu kei roto i te TPE, me whakanui ake pea te utaina o ngā mea ārai mura (ka taea e te hinu te whakaiti i te whai huatanga o te ārai mura).

Mā te whakaranu whaitake me te arotau whakamātautau, ka taea te whakatutuki i te tutuki i ngā whakaritenga UL94 V0 me te whakataurite i te kaha tukatuka TPE me te mahi miihini. E taunakihia ana te mahi tahi me ngā kaiwhakarato ārai mura mō ngā otinga ritenga.
