PP V2 Te Whakatairanga Tohutoro Masterbatch Retardant Flame Retardant
Mo te whakatutuki i te UL94 V2 te mura o te mura i roto i te PP (polypropylene) masterbatches, ka hiahiatia he huinga whakakotahitanga o nga mura ahi i te wa e mau tonu ana te mahi tukatuka me nga taonga miihini. Kei raro nei he taunakitanga whakatakotoranga papai me nga whakamarama:
I. Tohutohu Hanga Turanga
Hanganga mo te mura ahi:
| Waehanga | Uta ana (wt%) | Whakaahuatanga Mahi |
| PP Resin | 50-60% | Kapia kaikawe (tohutohu tohu tohu tohu rerenga whakarewa teitei, hei tauira, MFI 20-30 g/10min) |
| Konumohe Hypophosphite | 15-20% | Ko te puna waikawa, te whakatairanga i te hanga waro, te pai o te waiariki mo te tukatuka PP |
| Zinc Borate | 5-8% | Ko te whakakoi i te mura o te ahi, ka pehi i te auahi me te whakaniko i te hau-waahanga mura |
| Te Mata-Whakarerekehia te Aluminium Hydroxide | 10-15% | Ko te pirau endothermic, ka whakaheke i te pāmahana ngingiha (te maimoatanga mata, hei tauira, te kaihoko hono silane, e taunaki ana) |
| Dipentaerythritol (Di-PE) | 5-8% | Te puna waro, ka hono tahi me te puna waikawa ki te hanga waro intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Ko te puna hau (taapiri e taunakitia ana), ka tukuna nga hau mokowhiti hei whakarei ake i te hau |
| Agent Anti-Dripping (PTFE) | 0.3-0.5% | Ka whakaiti i te maturuturu rewa (he kowhiringa mo te V2, i te mea ka whakaaetia te maturuturu) |
| Huaora (1010/168) | 0.3-0.5% | Ka aukati i te whakahekenga waiariki i te wa e tukatuka ana |
| Whakahinuhinu (Zinc Stearate) | 0.5-1% | Te whakapai ake i te rere o te tukatuka me te marara |
| Kawe Tae & Pigment | Ina hiahiatia | Tīpakohia nga poaka-nui-a-te-a-te-te-nui kia kore e tauhohenga me nga parenga mura |
II. Nga Tohu Arotautanga Matua
- Synergistic Flame Retardant System
- Kore Te mura o te mura (IFR):Ko te konumohe hypophosphite (puna waikawa) + Di-PE (puna waro) + MPP (puna hau) ka hanga i te punaha IFR, ka hangaia he paparanga char insulating hei aukati i te wera me te hāora.
- Ko te Zinc Borate Synergy:Ka tauhohe ki te konumohe hypophosphite ki te hanga i te paparanga whakamarumaru kaata, ka whakarei ake i te whakaroa i te mura o te hau.
- Konumohe Waiwaiwai kua whakarereketia:Ko te maimoatanga o te mata he whakaiti i te tuku makuku i te wa e tukatuka ana i te wa e tuku ana te pirau endothermic ki te whakaheke i te wera wera.
- Tukatuka & Taurite Mahinga
- Me whakahaere katoa te utaina o te mura ahi35-45%ki te karo i te ngaronga nui o nga taonga miihini.
- Whakamahiteitei-MFI PP kapia (hei tauira, PPH-Y40)hei whakapai ake i te marara masterbatch me te whakaiti i te pokey.
- Nga Tohunga Whakamatau me te Whakamana
- UL94 Whakamātautau Tahu Poutū:Me whakarite kia tinei te mura o roto60 hēkonai muri i nga mura e rua.
- Whakamātautau Hangarau:Arotahi ki te kaha tensile (≥20 MPa) me te kaha pānga (≥4 kJ/m²).
- Pūmautanga Ngawha (TGA):Manatokohia kia rite nga pāmahana whakangao mura ki te awhe tukatuka PP (180–220°C).
III. Whakaritenga Kōwhiringa
- Mo te Mua Mua Teitei (hei tauira, V0):
- Whakanuia te konumohe hypophosphite ki25%, tāpiri2% silicone(paowa pehi), me te whakaara PTFE ki0.8%.
- Taupānga Utu-Araunga:
- Whakaitihia te ihirangi MPP me te whakanui ake i te konumohe hydroxide (whakaritea te pumau o te tukatuka).
IV. Nga Whakaaro Matua
- Whakaputa Maarahi:Whakaranu i mua i te mura ahi me te kapia kawe;tangohanga mahanga-wiri (180–210°C)e taunaki ana.
- Te whakamaroke Konumohe Hydroxide:Ka maroke i110°C mo te 4 haorahei aukati i nga mirumiru i te wa e tukatuka ana.
- Di-PE/Konumohe Hypophosphite Ratio:Mau tonu1:2 ki te 1:3mo te tino pai o te hanga char.
Na tenei hanganga tino pai me te huarahi tukatuka,UL94 V2 mura muraKa taea te whakatutuki i nga wa katoa i te wa e pupuri ana i nga mahi tukatuka me te pumau o te tae. Ka tūtohuhia nga whakamatautau iti mo te whakatikatika i runga i nga hua whakamatautau.
