Te Hanganga Tohutoro Masterbatch Ārai Mumura PP V2
Hei whakatutuki i te ātete mura UL94 V2 i roto i ngā puranga matua PP (polypropylene), me whakakotahi te whakakotahitanga o ngā ātete mura me te pupuri tonu i te mahi tukatuka me ngā āhuatanga miihini. Kei raro nei he taunakitanga whakatakotoranga kua arotauhia me ngā whakamārama:
I. Taunakitanga mō te Hanga Pūtake
Te Hanganga Ārai Mura:
| Wāhanga | Utaina (wt%) | Whakaahuatanga Mahi |
| Resin PP | 50-60% | Te kapia kawe (e taunakihia ana te taumata rere rewa teitei, hei tauira, MFI 20-30 g/10min) |
| Konumohe Hypophosphite | 15-20% | Pūtake waikawa, e whakatairanga ana i te hanganga waro, he pumau wera pai mō te tukatuka PP |
| Konutea Pōrata | 5-8% | He ārai mura tahi, he pehi i te paowa, ā, he whakarei ake i te ārai mura hau-āhuatanga |
| Te Waikawa Konumohe Kua Whakarerekētia te Mata | 10-15% | Te wetewete i roto i te werawera, ka whakaiti i te pāmahana tahunga (ka tūtohutia te maimoatanga mata, hei tauira, te kaihoko hononga silane) |
| Dipentaerythritol (Di-PE) | 5-8% | Pūtake waro, ka mahi tahi me te pūtake waikawa hei hanga i te waro intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Pūtake hau (tāpiritanga e taunakitia ana), ka tukuna ngā hau kore mahi hei whakarei ake i te puku |
| Ārai-Tārere (PTFE) | 0.3-0.5% | Ka whakaiti i te maturuturunga rewa (he kōwhiringa mō te V2, nā te mea e whakaaetia ana te maturuturunga) |
| Ārai Matekiri (1010/168) | 0.3-0.5% | Ārai i te pirau waikura wera i te wā tukatuka |
| Hinu Whakahinuhinu (Konutea Stearate) | 0.5-1% | Whakapai ake i te rere o te tukatuka me te marara |
| Kawe Tae me te Tae | E ai ki te hiahia | Kōwhiria ngā tae e ātete ana ki te pāmahana teitei hei karo i ngā tauhohenga ki ngā mea ārai mura |
II. Ngā Wāhanga Matua mō te Arotautanga
- Pūnaha Ārai Mura Tahi
- Kore Te mura o te mura (IFR):Ka hangaia he pūnaha IFR e te konumohe hypophosphite (pūtake waikawa) + Di-PE (pūtake waro) + MPP (pūtake hau), e hanga ana i tētahi paparanga waro hei ārai i te wera me te hāora.
- Te Mahi Tahi o te Konutea Borate:Ka tauhohe ki te konumohe hypophosphite hei hanga i tētahi paparanga tiaki karāhe, ka whakarei ake i te ātete mura āhua-hau.
- Te Waikawa Konumohe Kua Whakarerekētia:Ka whakaitihia e te maimoatanga mata te tukunga makuku i te wā e tukatukahia ana, ā, ka whakaratohia he pirau endothermic hei whakaiti i te pāmahana tahunga.
- Taurite Tukatuka me te Mahi
- Me whakahaere te kawenga ātete mura katoa i35-45%kia kore ai e ngaro nui te āhuatanga miihini.
- Whakamahiakapia PP MFI-teitei (hei tauira, PPH-Y40)hei whakapai ake i te mararatanga o te masterbatch me te whakaiti i te matotoru.
- Ngā Taunakitanga Whakamātautau me te Whakamana
- Whakamātautau Tahu Poutū UL94:Kia tino tineia ngā mura i roto i a rātou anō60 hēkonai muri i ngā tahunga e rua.
- Whakamātautau Mīhini:Arotahi ki te kaha kume (≥20 MPa) me te kaha o te pānga (≥4 kJ/m²).
- Te Pūmautanga Wera (TGA):Kia mōhio kei te ōrite ngā pāmahana pirau ātete mura ki te awhe tukatuka PP (180–220°C).
III. Ngā Whakarerekētanga Kōwhiringa
- Mō te Ātete Mura Nui Ake (hei tauira, V0):
- Whakanuia te hypophosphate konumohe ki25%, tāpiri2% silicon(te pehi paowa), me te whakaara ake i te PTFE ki0.8%.
- Ngā tono tairongo-utu:
- Whakaitihia te nui o te MPP, ā, whakanuia ake te hauwai konumohe (kia pumau te tukatuka).
IV. Ngā Whakaaro Matua
- Te Hanganga Matua-putanga:Whakaranua i mua ngā ārai mura me te kapia kawe;te whakaputanga takirua-wiri (180–210°C)e taunakitia ana.
- Te Whakamaroke i te Hauwai Konumohe:Maroke i110°C mō ngā hāora e 4hei ārai i ngā mirumiru i te wā e tukatuka ana.
- Di-PE/Konumohe Hypophosphite Ratio:Pupuri1:2 ki te 1:3mō te whai huatanga tino pai o te hanganga waro.
Mā tēnei huarahi whakatakotoranga me te tukatuka kua arotauhia,Ātete mura UL94 V2ka taea te whakatutuki i ngā wā katoa me te pupuri tonu i te mahi tukatuka me te pumau o te tae. E taunakihia ana kia whakatikatikahia ngā whakamātautau iti i runga i ngā hua o te whakamātautau.
