Ngā Pūrongo - Ngā Otinga Si-TPV 2250 mō ngā Rauemi Pahuka EVA Tino Whakamarie, Pakari, me te Whai Hua

Ngā otinga Si-TPV hei whakarei ake i te whakamarie, te pakari, me te whai huatanga o te whakaputa i roto i ngā rauemi pahuka EVA

Ngā Wero mō te Ngaronga Whakahoki Pahu EVA me te Pumau o ngā Hu

He maha ngā kaihanga hu e pāngia ana e tētahi wero roa:Te ngaronga o te pekepeke o te pahuka EVA tae atu ki te 10%i muri i te rokiroki, i te whakamahinga roa rānei. Ka pā te hekenga o te pakari ki te whakamarie o te waenga o te waewae, ka whakaiti i te pakari o te hu EVA, ā, ka piki ake ngā amuamu a te kiritaki me ngā reiti hokinga mai.

Tuku IhoEVA + SEBSHe maha ngā wā ka pāngia ngā pūnaha e:

• kāore i te rawaka te matotoru o te hononga whakawhiti,

• te whakangāwari o te mekameka ngota,

• Kāore e hototahi ki te tohu SEBS.

Ka whai wāhi ēnei take ki te hekenga o te mahi, te kore pumau o ngā āhuatanga, me te whakaoranga pūmau koretake.

Ngā Wero ki te Huka EVA me ngā Otinga Kua Whakamātauhia

Ngā Otinga Hangarau hei Whakapai ake i te Pūmautanga o te Whakahokinga Pahu EVA
1. Te Arotautanga o te Hanganga
1.1 Whakapai ake i te Kīanga Hononga Whakawhiti
Whakanuia te DCP mā te 10–20% ka tāpirihia te 0.1–0.2 phr TAIC hei whakapakari i te hanganga whatunga me te whakau i te mahi pahuka mō te wā roa.
1.2 Kōwhiria ngā Tohu SEBS Whakahoki-Teitei
Whakamahia ngā SEBS he kaha ōna āhuatanga ārai-whakaiti hei pupuri i te pumau o te mekameka ngota. Tāpirihia ki ngā SEBS pakeke ake hei whakapai ake i te kaha kume me te ātete ki te kakahu.
1.3 Te Whakamahinga Tāpiri Whaitake
Āta karohia ngā mea whakapūmau taumaha-iti.
Tāpirihia he 1–2 phr nano CaCO₃, he silica rānei hei whakapakari i te angaanga pahuka.
Whakahaerehia te ōwehenga pahuka i waenga i te 1.8–2.2 kia pai ake ai te ōrite o ngā pore.

2. Te Arotautanga o te Tukanga
• Whakanuia te pāmahana whakamaroke mā te 5–10°C (hei tauira, 160°C → 165–170°C).
• Whakaroahia te wā whakamaroke mā te 3–5 meneti kia tino honoa ai.
• Whakamahia te pakeketanga tuarua i te 80°C mō ngā hāora e 2 hei tuku i te ahotea o roto, hei whakarei ake hoki i te pumau o te whakahokinga mai mō te wā roa.
