Flame Retardant Solutions yePET Sheet Mafirimu
Mutengi anogadzira mafirimu ePET sheet akajeka-anodzoreredza ane ukobvu kubva pa0.3 kusvika 1.6 mm, achishandisa hexaphenoxycyclotriphosphazene (HPCTP) uye anotsvaga kudzikiswa kwemutengo. Pazasi pane akakurudzirwa magadzirirwo uye ongororo yakadzama yeakajeka murazvo-retardant PET mafirimu:
1. Kuongororwa kweFlame Retardant Selection
Hexaphenoxycyclotriphosphazene (HPCTP)
- Zvakanakira: Phosphazene-based flame retardants inopararira zvakanaka muPET, ichichengeta yakakwira pachena. Iyo inodzoreredza moto meshini inosanganisira condensed-phase charring uye gasi-chikamu radical trapping, zvichiita kuti ive yakakodzera mafirimu akajeka.
- Dosage: Inokurudzirwa pa5% -10%. Yakawandisa huwandu inogona kukanganisa mechanical properties.
- Mutengo: Zvine mwero, asi mutengo wakakwana unoramba uchidzoreka pakurodha pasi.
Aluminium Hypophosphite
- Zvakaipa: Inorganic poda inogona kukonzera mhute, ichikanganisa kujeka. Ultra-yakanaka particle saizi kana kugadziridzwa kwepasi kunogona kudikanwa kuti ugone kushandiswa.
- Kushanda: Hazvikurudzirwi chete; inogona kusanganiswa neHPCTP kudzikisa mutengo wakazara (kuongororwa pachena kunodiwa).
2. Yakakurudzirwa Kugadzira Sarudzo
Sarudzo 1: Single HPCTP System
- Kugadzira: 8% -12% HPCTP + PET base zvinhu.
- Mabhenefiti: Kujeka kwakaringana uye yakakwira-inodzoreredza murazvo (inogona kuwana UL94 VTM-2 kana VTM-0).
- Mutengo Yekufungidzira: Pa10% kurodha, mutengo wekuwedzera pakg yePET inenge ¥10 (¥100/kg × 10%).
Sarudzo yechipiri: HPCTP + Aluminium Hypophosphite Blend
- Kugadzira: 5% HPCTP + 5% -8% aluminium hypophosphite + PET base zvinhu.
- Zvakanakira: Kuderedzwa kwemutengo, nealuminium hypophosphite inobatsira mugasi-chikamu chemoto kunonoka, zvinogona kuderedza kushandiswa kweHPCTP.
- Ongorora: Kujeka kunofanirwa kuyedzwa (aluminium hypophosphite inogona kukonzera hunyoro hushoma).
3. Kugadzirisa uye Kuedza Mazano
- Dispersion process: Shandisa mapatya-screw extruder kuve nechokwadi chekupararira kweyunifomu yezvinodzosa moto uye kudzivirira kusangana kunokanganisa kujeka.
- Flame Retardancy Testing: Ongorora maererano neUL94 VTM kana Oxygen Index (OI) zviyero, kunanga OI> 28%.
- Transparency Testing: Kuyera mhute uchishandisa mhute mita, kuona haze <5% (firimu ukobvu: 0.3-1.6 mm).
4. Kuenzanisa Kwemari
Flame Retardant Loading uye Mutengo Wekuwedzera Tafura
| Flame Retardant | Loading | Mutengo Wedzero pakg PET |
|---|---|---|
| HPCTP (isina) | 10% | ¥10 |
| HPCTP + Aluminium Hypophosphite | 5% + 5% | ¥6.8 [(5×100 + 5×37)/100] |
| Aluminium Hypophosphite (imwe chete) | 20% | ¥7.4 (hazvikurudzirwe) |
5. Mhedziso
- Sarudzo Inodiwa: HPCTP yega pa8% -10%, kuenzanisa pachena uye kunonoka kwemurazvo.
- Imwe Sarudzo: Musanganiswa weHPCTP uye aluminium hypophosphite, inoda kuongororwa kwekujeka uye synergistic mhedzisiro.
Kurudziro: Mutengi anofanira kutanga aita zviyedzo zvidiki, achitarisa kunonoka kwemurazvo (UL94/OI) uye kuyedzwa kwemhute, wozokwidziridza magadzirirwo nemaitiro. Kana kumwe kudzikiswa kwemutengo kuchidikanwa, ongorora pamusoro-yakagadziridzwa aluminium hypophosphite kana novel phosphorus-based flame retardants.
