Konumohe Hypophosphite ātete mura me te MCA mō ngā Ngongo Whakaiti-wera EVA

Ina whakamahia te konumohe hypophosphite, te MCA (melamine cyanurate), me te konupora hauwai hei ārai mura i roto i ngā ngongo whakaheke wera EVA, ko ngā awhe horopeta kua tūtohutia me ngā tohutohu whakapai ake koia ēnei:

1. Te Inenga e Manakohia ana mō ngā Ārai Mumura

Konumohe Hypophosphite

Inenga:5%–10%
Mahi:He ārai mura tino whai hua, e whakatairanga ana i te hanganga waro, ā, e whakaiti ana i te tere tuku wera.
Tuhipoka:Ka pā kino pea te nui rawa o ngā rauemi ki te ngāwari o te rauemi; me whakauru ngā kaihoko mahi tahi hei whakapai ake i te kounga o ngā rauemi.

MCA (Melamine Cyanurate)

Inenga:10%–15%
Mahi:He ārai mura āhua-hau, ka mimiti i te wera, ka tuku i ngā hau kore mahi (hei tauira, NH₃), ka mahi tahi me te konumohe hypophosphite hei whakarei ake i te ātete mura.
Tuhipoka:Tērā pea ka heke te taonga ina nui rawa te uta; me whakarite kia hototahi ki te EVA.

Konupūmā Hauwai (Mg(OH)₂)

Inenga:20%–30%
Mahi:Ka tukuna te mamaoa wai e te pirau endothermic, ka whakawaiwai i ngā hau mura, ka pehi hoki i te paoa.
Tuhipoka:Tērā pea ka whakaitihia ngā āhuatanga ā-pūkaha e te taumahatanga nui; me whakarerekē te mata hei whakapai ake i te horapa.

2. Ngā Taunakitanga mō te Arotautanga o te Hanganga

Pūnaha Ārai Mura Katoa:Kaua e neke atu i te 50% hei whakataurite i te ātete mura me te ngāwari tukatuka (hei tauira, te ngāwari, te tere whakaheke).
Ngā Pānga Whakakotahi:
Ka taea e te konumohe hypophosphate me te MCA te whakaiti i ngā horopeta takitahi (hei tauira, 8% konumohe hypophosphate + 12% MCA).
Ka whakarei ake te konupora hauwai i te ātete mura mā ngā pānga werawera me te whakaiti i te paowa.
Te maimoatanga mata:Ka taea e ngā kaihoko hononga silane te whakarei ake i te mararatanga me te hononga ā-kanohi o te konupora hauwaiwai.
Ngā Tāpiri Āwhina:
Tāpirihia he 2%–5% ngā matū hanga waro (hei tauira, pentaerythritol) hei whakapai ake i te pumau o te paparanga waro.
Tāpirihia he iti noa o ngā mea whakapūmau kirihou (hei tauira, te hinu pīni soya kua whakapūmautia) hei whakakapi mō te ngaronga o te ngāwari.

3. Ngā Tohutohu Whakamana Mahi

Whakamātautau Ārai Mura:
Whakamātautau mura poutū UL94 (whāinga: V-0).
Te Taupū Hāora Whakawhāiti (LOI >28%).
Ngā Āhuatanga Ā-ringa:
Aromātaihia te kaha kume me te toronga i te wā whati kia mōhio ai kei te tutuki te ngāwari i ngā whakaritenga tono.
Te Āheinga o te Tukatuka:
Aroturukihia te Taupū Rere Rewa (MFI) hei karo i ngā uauatanga tukatuka nā te nui rawa o ngā whakakī.

4. Ngā Whakaaroaro mō te Utu me te Taiao

Taurite Utu:He nui te utu o te konumohe hypophosphate; ka taea te whakaiti i tōna horopeta (me te tāpiri atu ki te MCA) hei whakahaere i ngā utu.
Te Aroha ki te Taiao:Kāore te konupora hauwai i te paitini, ā, kāore hoki e pehi i te paowa, nō reira he pai mō ngā whakamahinga e pai ana mō te taiao.

Tauira Whakatakotoranga (hei tohutoro anake):
