Litharollo tse Sireletsang Mollo bakeng sa Lifilimi tsa Maqephe a PET
Moreki o hlahisa lifilimi tsa PET tse bonaletsang tse thibelang malakabe tse nang le botenya bo tlohang ho 0.3 ho isa ho 1.6 mm, a sebelisa hexaphenoxycyclotriphosphazene (HPCTP) 'me o batla phokotso ea litšenyehelo. Ka tlase ke mekhoa e khothaletsoang le tlhahlobo e qaqileng bakeng sa lifilimi tsa PET tse thibelang malakabe tse bonaletsang:
1. Tlhahlobo ea Khetho ea Sethibela-mollo
Hexaphenoxycyclotriphosphazene (HPCTP)
- Melemo: Dithibela-mollo tse thehilweng ho Phosphazene di hasanya hantle ho PET, di boloka ponaletso e phahameng. Mokgwa wa ho thibela mollo o kenyelletsa ho tjhesa ha mokgahlelo o kobehileng le ho tshwasa radical ya mokgahlelo wa kgase, e leng se etsang hore e lokele difilimi tse bonaletsang.
- Tekanyo: E kgothaletswa ho 5%-10%. Bongata bo feteletseng bo ka ama thepa ya mechini.
- Litšenyehelo: Li phahame haholo, empa litšenyehelo tsohle li ntse li laoleha ha ho jarisoa thepa ka bongata bo tlase.
Hypophosphite ea Aluminium
- Mathata: Phofo e sa pheleng e ka baka mouwane, e amang ponaletso. Boholo ba dikarolwana tse nyane haholo kapa phetoho ya bokahodimo e ka hlokahala bakeng sa tshebediso e ka bang teng.
- Ho sebetsa: Ha e kgothaletswe e le nngwe feela; e ka kopanngwa le HPCTP ho fokotsa ditjeo ka kakaretso (ho hlokahala teko ya ponaletso).
2. Dikgetho tse kgothaletswang tsa ho etsa ditokisetso
Khetho ea 1: Sistimi e le 'Ngoe ea HPCTP
- Tlhahiso: 8%-12% thepa ea motheo ea HPCTP + PET.
- Melemo: Ponaletso e ntle ka ho fetisisa le bokgoni bo phahameng ba ho thibela malakabe (e ka fihlella UL94 VTM-2 kapa VTM-0).
- Khakanyo ea Litšenyehelo: Ha ho jarisoa ka 10%, keketseho ea litšenyehelo ka kg ea PET e ka ba ¥10 (¥100/kg × 10%).
Khetho ea 2: Motsoako oa HPCTP + Aluminium Hypophosphite
- Sebopeho: 5% HPCTP + 5%-8% aluminium hypophosphite + thepa ea motheo ea PET.
- Melemo: Phokotso ea litšenyehelo, ka aluminium hypophosphite e thusang ho lieha ha lelakabe la khase, e leng se ka fokotsang tšebeliso ea HPCTP.
- Hlokomela: Ponaletso e lokela ho lekoa (aluminium hypophosphite e ka baka lerootho le lenyenyane).
3. Litlhahiso tsa Ts'ebetso le Teko
- Mokhoa oa ho Hasana: Sebelisa sesebelisoa sa ho ntša lintho tse peli ho netefatsa hore lintho tse thibelang malakabe li hasana ka ho lekana le ho qoba ho kopana ho amang ponaletso.
- Teko ea ho Fokotsa Lelakabe: Lekola ho latela maemo a UL94 VTM kapa Oxygen Index (OI), o shebane le OI > 28%.
- Teko ea Ponaletso: Lekanya mosi o sebelisang sesebelisoa sa ho lekanya mosi, ho netefatsa mosi o ka tlase ho 5% (botenya ba filimi: 0.3-1.6 mm).
4. Papiso ea Litšenyehelo
Tafole ea ho Laela le ho Eketsa Litšenyehelo ka Mollo
| Se thibelang malakabe | Ho ntse ho jarolloa | Keketseho ea Litšenyehelo ka PET ka kg |
|---|---|---|
| HPCTP (e le 'ngoe) | 10% | ¥10 |
| HPCTP + Aluminium Hypophosphite | 5% + 5% | ¥6.8 [(5×100 + 5×37)/100] |
| Aluminium Hypophosphite (e le 'ngoe) | 20% | ¥7.4 (ha e kgothaletswe) |
5. Qetello
- Khetho e Ratwang: HPCTP e le 'ngoe ho 8%-10%, e leka-lekanya ponaletso le ho lieha ha lelakabe.
- Khetho e 'Ngoe: Motsoako oa HPCTP le hypophosphite ea aluminium, e hlokang netefatso ea pepeneneng le litlamorao tsa tšebelisano-'moho.
Keletso: Moreki o lokela ho etsa liteko tse nyane pele, a shebane le ho thibela malakabe (UL94/OI) le ho lekoa ha mosi, ebe o ntlafatsa mokhoa oa ho etsa le ts'ebetso. Haeba ho hlokahala phokotso e eketsehileng ea litšenyehelo, hlahloba li-hypophosphite tsa aluminium tse fetotsoeng holim'a metsi kapa li-flame tse ncha tse thehiloeng ho phosphorus.
