PP V2 Ọkụ Retardant Masterbatch Ntuziaka
Maka inweta UL94 V2 ire ọkụ retardancy na PP (polypropylene) masterbatches, a chọrọ nchikota synergistic nke ire ere mgbe ị na-ejigide ọrụ nhazi na akụrụngwa akụrụngwa. N'okpuru bụ ntụnye nhazi kachasị mma nwere nkọwa:
I. Nkwanye nhazi ntọala
Nhazi nke ire ọkụ:
| Akụkụ | Na-ebu (wt%) | Nkọwa ọrụ |
| PP resin | 50-60% | Ebube resin (na-akwado ọkwa ọkwa mgbaze mgbaze dị elu, dịka MFI 20-30 g/10min) |
| Aluminom hypophosphite | 15-20% | Isi iyi acid, na-akwalite nhazi cha cha, nkwụsi ike dị mma maka nhazi PP |
| Zinc borate | 5-8% | Ọ na-egbochi ire ọkụ na-emekọrịta ihe, na-egbochi anwụrụ ọkụ ma na-akwalite ogologo oge ire ọkụ nke gas. |
| Aluminom Hydroxide gbanwechara n'elu | 10-15% | Nreka endothermic, na-ebelata okpomọkụ ọkụ (ọgwụgwọ ihu, dịka ọmụmaatụ, onye na-ejikọta silane, akwadoro) |
| Dipentaerythritol (Di-PE) | 5-8% | Isi iyi carbon, na-ejikọta ya na isi iyi acid iji mepụta cha cha intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Isi iyi gas (mgbakwunye akwadoro), na-ahapụ gas inert iji kwalite intumescence |
| Ihe mgbochi mgbochi mmiri (PTFE) | 0.3-0.5% | Na-ebelata mgbaze mmiri (nhọrọ maka V2, dịka ekwenyere ịfe mmiri) |
| Antioxidant (1010/168) | 0.3-0.5% | Na-egbochi mmebi oxidative thermal n'oge nhazi |
| Mmanu mmanu (Zinc Stearate) | 0.5-1% | Na-eme ka nhazi usoro na mgbasa |
| Onye na-ebu agba & pigmenti | Dị ka ọ dị mkpa | Họrọ pigmenti na-eguzogide okpomọkụ dị elu ka ịzenarị mmeghachi omume site na ọkụ retardants |
II. Isi ihe nkwalite
- Sistemụ Retardant Synergistic Flame Retardant
- Ihe na-egbochi ire ọkụ (IFR):Aluminom hypophosphite (isi iyi acid) + Di-PE (isi iyi carbon) + MPP (isi iyi gas) na-etolite sistemu IFR, na-emepụta akwa mkpuchi mkpuchi iji gbochie okpomọkụ na ikuku oxygen.
- Mmekọrịta Zinc Borate:Na-emeghachi omume na aluminom hypophosphite ka ọ mepụta oyi akwa mkpuchi enyo, na-eme ka ọ kwụsịlata ire ọkụ n'usoro gas.
- Aluminom Hydroxide agbanweela:Ọgwụgwọ dị n'elu na-ebelata ntọhapụ mmiri n'oge nhazi ebe ọ na-enye ire ere endothermic iji belata okpomọkụ ọkụ.
- Nhazi & Ntụle arụmọrụ
- Ekwesịrị ịchịkwa mkpokọta ọkụ na-egbochi ibunye na35-45%iji zere nnukwu n'ibu ihe onwunwe ọnwụ.
- Jiriresin PP MFI dị elu (dịka, PPH-Y40)ka mma masterbatch mgbasa ma belata viscosity.
- Nnwale & Nkwado Nkwanye
- Nnwale ọkụ kwụ ọtọ UL94:Gbaa mbọ hụ na ọkụ na-emenyụ onwe ya n'ime60 sekọndmgbe abụọ ignitions.
- Nnwale igwe:Lekwasị anya na ike tensile (≥20 MPa) na ike mmetụta (≥4 kJ/m²).
- Nkwụsi ike nke okpomọkụ (TGA):Nyochaa ogo ire ere ire ọkụ dakọtara na nso nhazi PP (180-220 Celsius C).
III. Ndozi nhọrọ
- Maka Nkwụghachi Ọkụ Dị Elu (dịka, V0):
- Mụbaa aluminom hypophosphite ka25%, tinye2% silicone(mbelata anwụrụ ọkụ), ma bulie PTFE gaa0.8%.
- Ngwa bara uru:
- Belata ọdịnaya MPP ma mee ka aluminom hydroxide dịkwuo ntakịrị (hụ na nkwụsi ike nhazi).
IV. Isi Ntụle
- Mmepụta Masterbatch:Tupu-agwakọta ire ere na resin ebu;extrusion ejima (180-210ºC)akwadoro.
- Aluminom Hydroxide ihicha:Akọrọ na110 Celsius C maka awa 4iji gbochie afụ n'oge nhazi.
- Oke Di-PE/Aluminom Hypophosphite Ratio:Jikwaa1:2 ruo 1:3maka ezigbo nhazi cha cha.
Site na usoro nhazi na nhazi a kachasị mma,UL94 V2 ire ere ọkụenwere ike nweta ya mgbe niile ka ị na-echekwa arụmọrụ nhazi na nkwụsi ike agba. A na-atụ aro nnwale ndị pere mpe maka ngbanwe nke ọma dabere na nsonaazụ ule.
