Litharollo tsa Flame Retardant bakeng sa lifilimi tsa PET Sheet
Moreki o hlahisa lifilimi tsa PET tse sa chesehang ka malakabe tse nang le botenya ho tloha ho 0.3 ho isa ho 1.6 mm, a sebelisa hexaphenoxycyclotriphosphazene (HPCTP) mme o batla ho fokotsa litšenyehelo. Ka tlase ke likhothaletso tse khothaletsoang le tlhahlobo e felletseng ea lifilimi tsa PET tse thibelang malakabe a pepenene:
1. Analysis of Flame Retardant Selection
Hexaphenoxycyclotriphosphazene (HPCTP)
- Melemo: Li-retardants tse thehiloeng ho phosphazene li hasana hantle ho PET, li boloka pepeneneng e phahameng. Mochine o thibelang malakabe o kenyelletsa ho chesoa ha "condensed-phase-charring" le "gas-phase radical trapping", e leng se etsang hore e loketse lifilimi tse pepeneneng.
- Tekanyetso: E khothaletsoa ho 5% -10%. Chelete e feteletseng e ka ama thepa ea mochini.
- Litšenyehelo: Ha ho bapisoa li phahame, empa litšenyehelo kaofela li lula li laoleha ha li jarolloa ka tlase.
Hypophosphite ea aluminium
- Mathata: Liphofshoana tse sa tloaelehang li ka baka moholi, tse amang pepeneneng. Ho ka 'na ha hlokahala boholo ba likaroloana tse ntle haholo kapa phetoho ea bokaholimo bakeng sa tšebeliso e ka bang teng.
- Tšebeliso: Ha e khothalletsoe feela; e ka kopanngoa le HPCTP ho fokotsa litšenyehelo tse akaretsang (ho hlokahala tlhahlobo ea ponaletso).
2. Likhetho tse khothalelitsoeng tsa ho theha
Khetho ea 1: Sistimi e le 'ngoe ea HPCTP
- Sebopeho: 8% -12% HPCTP + PET lisebelisoa tsa motheo.
- Melemo: Ponaletso e nepahetseng le ts'ebetso e phahameng e thibelang malakabe (e ka fihlela UL94 VTM-2 kapa VTM-0).
- Khakanyo ea Litšenyehelo: Ho 10% ho laela, keketseho ea litšenyehelo ka kg ea PET e ka ba ¥10 (¥100/kg × 10%).
Khetho ea 2: HPCTP + Aluminium Hypophosphite Blend
- Sebopeho: 5% HPCTP + 5% -8% aluminium hypophosphite + lisebelisoa tsa motheo tsa PET.
- Melemo: Ho fokotsa litšenyehelo, ka aluminium hypophosphite e thusang ho fokotsa lelakabe la khase, e leng monyetla oa ho fokotsa tšebeliso ea HPCTP.
- Tlhokomeliso: Ponaletso e tlameha ho lekoa (aluminium hypophosphite e ka baka moholi o monyane).
3. Litlhahiso tsa Ts'ebetso le Tlhahlobo
- Ts'ebetso ea Phatlalatso: Sebelisa sekoahelo sa marang-rang ho etsa bonnete ba ho hasana ha li-flame retardants le ho qoba ho kopana ho amang pepeneneng.
- Teko ea ho Rata Lelakabe: Hlahloba ho ea ka litekanyetso tsa UL94 VTM kapa Oxygen Index (OI), ho lebisa tlhokomelo ea OI> 28%.
- Teko ea Transparency: Lekanya moholi o sebelisa mithara ea moholi, ho netefatsa hore haze <5% (botenya ba filimi: 0.3-1.6 mm).
4. Papiso ea Litšenyehelo
Letlapa le Retardant Loading le Lethathamo la Keketso ea Litšenyehelo
| Lelakabe le Retardant | Loading | Litsenyehelo Keketso ka kg PET |
|---|---|---|
| HPCTP (e le mong) | 10% | ¥10 |
| HPCTP + Aluminium Hypophosphite | 5% + 5% | ¥6.8 [(5×100 + 5×37)/100] |
| Aluminium Hypophosphite (e le 'ngoe) | 20% | ¥7.4 (ha e khothalletsoe) |
5. Qetello
- Khetho e Ratoang: HPCTP feela ho 8% -10%, ho leka-lekanya ponaletso le ho lieha ha lelakabe.
- Khetho e 'ngoe: Motsoako oa HPCTP le aluminium hypophosphite, e hlokang ho netefatsoa ha ponaletso le litlamorao tsa synergistic.
Keletso: Moreki o lokela ho etsa liteko tse nyane pele, a shebane le ho lieha ha malakabe (UL94/OI) le tlhahlobo ea moholi, ebe o ntlafatsa sebopeho le ts'ebetso. Haeba ho hlokahala phokotso e eketsehileng ea litšenyehelo, hlahloba aluminium hypophosphite e fetotsoeng ka holim'a metsi kapa li-flame retardants tse thehiloeng ho phosphorus.
