Nhazi ntụaka Masterbatch nke PP V2 Flame Retardant
Iji nweta ihe mgbochi ire ọkụ UL94 V2 na masterbatches PP (polypropylene), a chọrọ njikọta nke ihe mgbochi ire ọkụ mgbe a na-ejigide arụmọrụ nhazi na akụrụngwa. N'okpuru ebe a bụ ndụmọdụ usoro kachasị mma yana nkọwa:
I. Nkwanye Ụkpụrụ Ntọala
Usoro Mgbochi Ọkụ:
| Akụkụ | Na-ebugo (wt%) | Nkọwa Ọrụ |
| PP Resin | 50-60% | Resin ebu (a na-atụ aro ọkwa nhazi mmiri gbazee dị elu, dịka ọmụmaatụ, MFI 20-30 g/nkeji 10) |
| Aluminom Hypophosphite | 15-20% | Isi iyi acid, na-akwalite nhazi char, ezigbo nkwụsi ike okpomọkụ maka nhazi PP |
| Zinc Borate | 5-8% | Ihe na-egbochi ire ọkụ nke ọma, na-egbochi anwụrụ ọkụ ma na-eme ka ire ọkụ nke gas dịkwuo mma |
| Aluminom Hydroxide E Megharịrị n'elu | 10-15% | Mmebi nke endothermic, na-ebelata okpomọkụ ọkụ (ọgwụgwọ elu, dịka ọmụmaatụ, ihe na-ejikọ silane, akwadoro) |
| Dipentaerythritol (Di-PE) | 5-8% | Isi iyi carbon, na-ejikọta ya na isi iyi acid iji mepụta char intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Isi iyi gas (mgbakwunye akwadoro), na-ewepụta gas ndị na-adịghị arụ ọrụ iji mee ka intumescence dịkwuo mma |
| Ihe Mgbochi Mbelata Mmiri (PTFE) | 0.3-0.5% | Na-ebelata mmiri ịgbaze (nhọrọ maka V2, ebe ọ bụ na a na-ekwe ka mmiri gbazee) |
| Ọgwụ mgbochi oxidant (1010/168) | 0.3-0.5% | Na-egbochi mmebi okpomọkụ nke oxidative n'oge nhazi |
| Mmanụ mmanu (Zinc Stearate) | 0.5-1% | Ọ na-eme ka nhazi na mgbasa dịkwuo mma |
| Onye na-ebu agba na agba | Dịka ọ dị mkpa | Họrọ agba ndị na-eguzogide okpomọkụ dị elu iji zere mmeghachi omume na ihe ndị na-egbochi ire ọkụ |
II. Isi Ihe Ndị Dị Mkpa Iji Mee Ka Ọ Ka Mma
- Sistemụ Nkwụsị Ọkụ Synergistic
- Ihe na-egbochi ire ọkụ (IFR):Aluminom hypophosphite (isi iyi asịd) + Di-PE (isi iyi carbon) + MPP (isi iyi gas) na-emepụta sistemụ IFR, na-emepụta oyi akwa char iji gbochie okpomọkụ na oxygen.
- Njikọta Zinc Borate:Ọ na-emeghachi omume na aluminom hypophosphite iji mepụta oyi akwa nchekwa iko, na-eme ka ọ ghara ịdị irè nke ukwuu site na gas-phase frage ire ọkụ.
- Aluminom Hydroxide emezigharịrị:Ọgwụgwọ elu na-ebelata mwepụta mmiri n'oge nhazi ebe ọ na-enye mmebi endothermic iji belata okpomọkụ ọkụ.
- Nhazi na Nhazi Arụmọrụ
- A ga-achịkwa ibu zuru oke nke ihe na-egbochi ire ọkụ na35-45%iji zere nnukwu mfu ihe onwunwe igwe.
- Jiriresin PP nke nwere MFI dị elu (dịka ọmụmaatụ, PPH-Y40)iji melite mgbasa nke masterbatch ma belata viscosity.
- Nnwale na Nkwenye Aro
- Ule Ọkụ Vertical nke UL94:Hụ na ọkụ na-agbanyụ onwe ya n'imeSekọnd iri isiimgbe ọkụ abụọ gasịrị.
- Nnwale Mekaniki:Lekwasị anya n'ike nrụgide (≥20 MPa) na ike mmetụta (≥4 kJ/m²).
- Nkwụsi Ike nke Okpomọkụ (TGA):Lelee okpomọkụ nke ire ọkụ dakọtara na oke nhazi PP (180–220°C).
III. Mgbanwe Nhọrọ
- Maka nkwụsịtụ ọkụ dị elu (dịka ọmụmaatụ, V0):
- Mee ka aluminom hypophosphite dịkwuo eluPasentị iri abụọ na isetinyeSilikọn 2%(ọgwụgwọ anwụrụ ọkụ), ma bulie PTFE ka ọ bụrụ0.8%.
- Ngwa Ndị Na-egosi Ọnụ Ego:
- Belata ọdịnaya MPP ma mụbaa aluminom hydroxide nke ọma (hụ na nhazi ahụ kwụsiri ike).
IV. Ihe Ndị Dị Mkpa A Ga-atụle
- Mmepụta ihe n'ọkwa ukwu:Gwakọta ihe ndị na-egbochi ire ọkụ tupu ha ejiri resin ebu;Mkpọpụta skru abụọ (180–210°C)a na-atụ aro ya.
- Ịkpọcha Aluminom Hydroxide:Kpọọ nkụ na110°C ruo awa anọiji gbochie afụfụ n'oge nhazi.
- Oke Di-PE/Aluminom Hypophosphite Ratio:Nọgide na-enwe1:2 ruo 1:3maka arụmọrụ nhazi chara acha kacha mma.
Site na usoro nhazi na nhazi a kachasị mma,Nkwụsị ire ọkụ UL94 V2enwere ike imezu ya mgbe niile ma na-echekwa arụmọrụ nhazi na nkwụsi ike agba. A na-akwado nnwale obere maka nhazi dabere na nsonaazụ ule.
