PP V2 Flame Retardant Masterbatch Yerekana Imiterere
Kugirango ugere kuri UL94 V2 flame retardancy muri PP (polypropylene) igishushanyo mbonera, harakenewe guhuza imbaraga za flame retardants mugihe gikomeza gutunganya no gutunganya imashini. Hano hepfo ni ibyifuzo byateguwe neza hamwe nibisobanuro:
I. Icyifuzo cyo Gushiraho
Flame Retardant formulaire:
| Ibigize | Kuremera (wt%) | Imikorere Ibisobanuro |
| PP Resin | 50-60% | Umwikorezi wa resin (saba urwego rwo hejuru rwo gushonga urwego, urugero, MFI 20-30 g / 10min) |
| Aluminium Hypophosphite | 15-20% | Inkomoko ya acide, iteza imbere char, gushiraho ubushyuhe bwiza bwo gutunganya PP |
| Zinc Borate | 5-8% | Gukoresha flame retardant, guhagarika umwotsi no kongera gaze-fase ya flame |
| Ubuso bwahinduwe na Aluminium Hydroxide | 10-15% | Kwangirika kwa Endothermic, kugabanya ubushyuhe bwo gutwikwa (kuvura hejuru, urugero, umukozi wa silane, birasabwa) |
| Dipentaerythritol (Di-PE) | 5-8% | Inkomoko ya karubone, ihuza hamwe na acide kugirango ikore char intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Inkomoko ya gaze (isabwa inyongera), irekura imyuka ya inert kugirango yongere intumescence |
| Umukozi urwanya ibiyobyabwenge (PTFE) | 0.3-0.5% | Kugabanya gutonyanga gushonga (birashoboka kuri V2, nkuko gutemba byemewe) |
| Antioxydants (1010/168) | 0.3-0.5% | Irinde kwangirika kwa okiside yumuriro mugihe cyo gutunganya |
| Amavuta (Zinc Stearate) | 0.5-1% | Itezimbere gutunganya no gutatana |
| Ibara ryamabara & Pigment | Nkuko bikenewe | Hitamo pigment irwanya ubushyuhe bwinshi kugirango wirinde kwitwara hamwe na retardants |
II. Ingingo z'ingenzi zo gukoresha neza
- Sisitemu ya Flame Retardant Sisitemu
- Intumecent Flame Retardant (IFR):Aluminium hypophosphite (isoko ya acide) + Di-PE (isoko ya karubone) + MPP (isoko ya gaze) ikora sisitemu ya IFR, ikora char insuline yo gukumira ubushyuhe na ogisijeni.
- Zinc Borate Synergy:Igisubizo hamwe na aluminium hypophosphite kugirango ikore ikirahure kirinda ibirahure, byongera ingufu za gaze ya fase.
- Guhindura Aluminium Hydroxide:Kuvura hejuru bigabanya irekurwa ryamazi mugihe cyo gutunganya mugihe utanga endothermic decomposition to ubushyuhe bwo gutwika.
- Gutunganya & Impirimbanyi
- Ibikoresho byose bya flame retardant bigomba kugenzurwa kuri35-45%kwirinda igihombo gikomeye cyumutungo.
- Koreshahejuru-MFI PP resin (urugero, PPH-Y40)kunoza masterbatch ikwirakwiza no kugabanya ububobere.
- Kwipimisha & Kwemeza Ibyifuzo
- UL94 Ikizamini Cyaka:Menya neza ko umuriro uzimya imbereAmasegonda 60nyuma yo gutwikwa kabiri.
- Ikizamini cya mashini:Wibande ku mbaraga zikomeye (≥20 MPa) n'ingaruka zingaruka (≥4 kJ / m²).
- Ubushyuhe bwumuriro (TGA):Kugenzura flame retardant decomposition ubushyuhe ihuye na PP yo gutunganya (180-220 ° C.).
III. Guhindura
- Kubirindiro Byinshi bya Flame (urugero, V0):
- Ongera aluminium hypophosphite kuri25%, Ongeraho2% silicone(guhagarika umwotsi), no kuzamura PTFE kuri0.8%.
- Ikiguzi-Cyunvikana Porogaramu:
- Mugabanye ibiri muri MPP kandi wongere muburyo buringaniye hydroxide ya aluminium (reba gutunganya neza).
IV. Ibitekerezo by'ingenzi
- Umusaruro wa Masterbatch:Mbere yo kuvanga flame retardants hamwe na resin yabatwara;gukuramo impanga (180-210 ° C)ni.
- Aluminium Hydroxide Kuma:Kuma kuri110 ° C mu masaha 4gukumira ibibyimba mugihe cyo gutunganya.
- Ikigereranyo cya Di-PE / Aluminium Hypophosphite:Komeza1: 2 kugeza 1: 3kubikorwa byiza byo gushiraho char.
Hamwe nuburyo bunoze bwo gutegura no gutunganya,UL94 V2 kutagira umuriroBirashobora kugerwaho muburyo bwo kubungabunga imikorere no gutunganya amabara. Ibigeragezo bito birasabwa guhuza neza ukurikije ibisubizo byikizamini.
