I-Polypropylene (PP) I-Flame Retardant Masterbatch iyinhlanganisela ephezulu yokugxila yamalangabi abushelelezi amalangabi kanye ne-carrier resin, esetshenziselwa ukwenza lula ukuguqulwa okungavimbeli ilangabi kwezinto ze-PP. Ngezansi ukwakheka nencazelo enemininingwane ye-PP flame retardant masterbatch:
I. Ukwakheka Okuyisisekelo kwe-PP Flame Retardant Masterbatch
- I-resin yenkampani yenethiwekhi: Ngokuvamile i-PP, iqinisekisa ukuhambisana okuhle nezinto eziyisisekelo.
- I-flame retardant: I-halogenated noma i-halogen-free, ekhethiwe ngokusekelwe ezidingweni.
- I-Synergist: Ithuthukisa ukuncipha komlilo (isb., i-antimony trioxide).
- Ukuhlakazeka: Ithuthukisa ukusakazeka kwama-flame retardants.
- Okokugcoba: Ithuthukisa uketshezi lokucubungula.
- Isiqinisi: Ivimbela ukuwohloka ngesikhathi sokucubungula.
II. I-Halogenated Flame Retardant PP Masterbatch Formulation
Ama-halogenated flame retardants (isb, brominated) ahlanganiswe ne-antimony trioxide anikeza ukusebenza kahle okuphezulu.
Ukwakhiwa Kwesibonelo:
- I-resin yenkampani yenethiwekhi (PP): 40-50%
- I-brominated flame retardant (isb, i-decabromodiphenyl ether noma i-brominated polystyrene): 30–40%
- I-Antimony trioxide (i-synergist): 5–10%
- I-Disperant (isb, i-polyethylene wax): 2-3%
- I-Lubricant (isb., i-calcium stearate): 1–2%
- I-Antioxidant (isb, 1010 noma 168): 0.5–1%
Ukucubungula Izinyathelo:
- Hlanganisa kuqala zonke izingxenye ngokulinganayo.
- Hlanganisa i-Melt usebenzisa i-twin-screw extruder kanye ne-peltize.
- Lawula izinga lokushisa le-extrusion ku-180–220°C.
Izici:
- Ukubambezeleka kwelangabi okuphezulu nokulayisha okungeziwe okuphansi.
- Ingakhulula amagesi anobuthi ngesikhathi sokusha.
- Ifanele izicelo ezinezidingo eziphansi zemvelo.
III. Ukwakhiwa kwe-Masterbatch ye-Halogen-Free Flame Retardant
Ama-halogen-free retardants (isb., i-phosphorus-, i-nitrogen-based, noma ama-inorganic hydroxides) ayavumelana nemvelo kodwa adinga ukulayishwa okuphezulu.
Ukwakhiwa Kwesibonelo:
- I-resin yenkampani yenethiwekhi (PP): 30–40%
- I-phosphorus-based retardant (isb, ammonium polyphosphate APP noma i-phosphorus ebomvu): 20–30%
- I-nitrogen-based retardant (isb, i-melamine cyanrate MCA): 10–15%
- I-Magnesium hydroxide noma i-aluminium hydroxide: 20-30%
- I-Disperant (isb, i-polyethylene wax): 2-3%
- I-Lubricant (isb., i-zinc stearate): 1–2%
- I-Antioxidant (isb, 1010 noma 168): 0.5–1%
Ukucubungula Izinyathelo:
- Hlanganisa kuqala zonke izingxenye ngokulinganayo.
- Hlanganisa i-Melt usebenzisa i-twin-screw extruder kanye ne-peltize.
- Lawula izinga lokushisa le-extrusion ku-180–210°C.
Izici:
- I-Eco-friendly, awekho amagesi anobuthi ngesikhathi sokusha.
- Ukulayisha okungeziwe okungaphezulu kungase kuphazamise izakhiwo zemishini.
- Ifanele izicelo ezinezindinganiso eziqinile zemvelo.
IV. Okucatshangelwayo Okubalulekile Kudizayini Yokwenza
- Ukukhetha i-flame retardant: Khetha i-halogenated noma i-halogen-free ngokusekelwe ekumelaneni nomlilo odingekayo kanye nemithethonqubo yemvelo.
- Ukuhambisana kwe-resin yenkampani yenethiwekhi: Kumelwe ihambisane nesisekelo se-PP ukuze kuvinjelwe i-delamination.
- Ukuhlakazeka: Izisabalalisi nezinto zokugcoba kuqinisekisa ukusatshalaliswa okufanayo kwama-retardants.
- Icubungula izinga lokushisa: Gwema ukushisa okukhulu ukuze uvimbele ukubola okungaboli.
- Izakhiwo zemishini: Ukulayisha okungeziwe okungeziwe kungase kwehlise ukusebenza; cabangela ama-toughening agents (isb, i-POE noma i-EPDM).
V. Izicelo Ezijwayelekile
- I-halogenated masterbatch: Izindlu zikagesi, izintambo/amakhebula.
- I-masterbatch yamahhala ye-halogen: Ingaphakathi lezimoto, izinto zokwakha, amathoyizi ezingane.
VI. Izincomo Zokuthuthukisa
- Thuthukisa ukulibaziseka komlilo: Hlanganisa ama-retardants amaningi (isb, i-phosphorus-nitrogen synergy).
- Thuthukisa izakhiwo zemishini: Engeza okokuqinisa (isb, i-POE/EPDM).
- Ukwehliswa kwezindleko: Lungiselela izilinganiso ze-retardant bese ukhetha izinto ezingabizi kakhulu.
Ngokwakhiwa okunengqondo kanye nokucubungula ukuklama, ama-masterbatches e-PP flame retardant angahlangabezana nezidingo ezihlukahlukene zohlelo lokusebenza.
Ngenxa yemithetho yezemvelo kanye nokushoda kokuhlinzekwa kwe-antimony trioxide, inani elandayo lamakhasimende amukela ama-flame retardant angenayo i-halogen ye-phosphorus-nitrogen kuma-PP masterbatches. Ngokwesibonelo,TF-241ingasetshenziswa ngokuqondile emikhiqizweni ye-PP nama-masterbatches, ukufeza imiphumela ezimele yokwakheka kwe-char kanye ne-intumescent ngaphandle kwezithasiselo ezengeziwe. Ukwandisa izakhiwo zemishini, amanani afanelekile ama-plasticizers nama-coupling agents ayanconywa.
