I-Polypropylene (PP) Flame Retardant Masterbatch iyinhlanganisela enokuhlushwa okuphezulu kwezinto ezigcina ilangabi kanye ne-carrier resin, esetshenziselwa ukwenza lula ukuguqulwa kwezinto ze-PP ezigcina ilangabi. Ngezansi kunencazelo eningiliziwe ye-PP flame retardant masterbatch:
I. Ukwakheka Okuyisisekelo kwe-PP Flame Retardant Masterbatch
- I-resin yesithwali: Ngokuvamile i-PP, okuqinisekisa ukuhambisana okuhle nezinto eziyisisekelo.
- Isivimbeli somlilo: I-Halogened noma i-halogen ayinayo, ikhethiwe ngokusekelwe ezidingweni.
- I-Synergist: Kuthuthukisa ukubambezeleka komlilo (isb., i-antimony trioxide).
- Isihlanzi: Kuthuthukisa ukusabalala kwezinto ezivimbela ilangabi.
- Isithambisi: Kuthuthukisa ukugeleza kokucubungula.
- Isiqinisi: Kuvimbela ukuwohloka ngesikhathi sokucubungula.
II. Ukwakheka kwe-Halogenated Flame Retardant PP Masterbatch
Izinto ezigcina ilangabi ezifakwe i-halogenated (isb., i-brominated) ezihlanganiswe ne-antimony trioxide zinikeza ukusebenza kahle okuphezulu.
Isibonelo Sokwakheka:
- I-resin yokuthwala (PP): 40–50%
- I-brominated flame retardant (isb., i-decabromodiphenyl ether noma i-brominated polystyrene): 30–40%
- I-antimony trioxide (i-synergist): 5–10%
- Isihlanzisi (isb., i-polyethylene wax): 2–3%
- Isithambisi (isb., i-calcium stearate): 1–2%
- I-Antioxidant (isib., 1010 noma 168): 0.5–1%
Izinyathelo Zokucubungula:
- Hlanganisa zonke izithako ngokulinganayo kusengaphambili.
- Ncibilikisa ingxube usebenzisa i-extruder enama-screw amabili bese uyixuba.
- Lawula izinga lokushisa lokukhipha ku-180–220°C.
Izici:
- Ukushisa kwelangabi okuphezulu okunomthwalo omncane wokwengeza.
- Kungakhipha amagesi anobuthi ngesikhathi sokusha.
- Kufanelekela izinhlelo zokusebenza ezinezidingo eziphansi zemvelo.
III. Ukwakheka kwe-PP Masterbatch Engenalo Ilangabi Eliyi-Halogen
Izinto ezigcina i-halogen zingenazo izinto ezibangela i-halogen (isb., i-phosphorus-, i-nitrogen-based, noma i-inorganic hydroxides) zinobungani nemvelo kodwa zidinga ukulayisha okuphezulu.
Isibonelo Sokwakheka:
- I-resin yokuthwala (PP): 30–40%
- I-retardant esekelwe kwi-phosphorus (isb., i-ammonium polyphosphate APP noma i-phosphorus ebomvu): 20–30%
- I-retardant esekelwe ku-nitrogen (isb., i-melamine cyanurate MCA): 10–15%
- I-Magnesium hydroxide noma i-aluminium hydroxide: 20–30%
- Isihlanzisi (isb., i-polyethylene wax): 2–3%
- Isithambisi (isb., i-zinc stearate): 1–2%
- I-Antioxidant (isib., 1010 noma 168): 0.5–1%
Izinyathelo Zokucubungula:
- Hlanganisa zonke izithako ngokulinganayo kusengaphambili.
- Ncibilikisa ingxube usebenzisa i-extruder enama-screw amabili bese uyixuba.
- Lawula izinga lokushisa lokukhipha ku-180–210°C.
Izici:
- Ivikela imvelo, ayinawo amagesi anobuthi ngesikhathi sokusha.
- Umthwalo ophezulu wokwengeza ungalimaza izakhiwo zemishini.
- Ifanele ukusetshenziswa ngezindinganiso eziqinile zemvelo.
IV. Izinto Ezibalulekile Okufanele Zicatshangelwe Ekwakhiweni Kwefomula
- Ukukhetha okubambezela ilangabi: Khetha i-halogen noma i-halogen-free ngokusekelwe ekumelaneni nomlilo okudingekayo kanye nemithethonqubo yezemvelo.
- Ukuhambisana kwe-resin yesithwali: Kumelwe ihambisane ne-base PP ukuze kuvinjelwe ukuhlukana.
- Ukuhlakazeka: Izihlanzi kanye nezinto zokugcoba ziqinisekisa ukusatshalaliswa okufanayo kwezihlanzi ezigcina umswakama.
- Ukushisa kokucubungula: Gwema ukushisa okweqile ukuze uvimbele ukubola okubambezelayo.
- Izakhiwo zemishini: Imithwalo ephezulu yokwengeza ingase yehlise ukusebenza; cabanga ngezinto zokuqinisa (isb., i-POE noma i-EPDM).
V. Izicelo Ezijwayelekile
- I-masterbatch ene-halogenated: Izindlu ze-elekthronikhi, izintambo/izintambo.
- I-masterbatch engena-Halogen: Ingaphakathi lezimoto, izinto zokwakha, amathoyizi ezingane.
VI. Izincomo Zokwenza Kusebenze Kahle
- Thuthukisa ukubambezeleka komlilo: Hlanganisa izinto ezibangela ukuguga eziningi (isib. ukusebenzisana kwe-phosphorus-nitrogen).
- Thuthukisa izakhiwo zemishini: Engeza izinto zokuqinisa (isb., i-POE/EPDM).
- Ukwehliswa kwezindleko: Lungiselela izilinganiso ezigcina umswakama futhi ukhethe izinto ezingabizi kakhulu.
Ngokwakhiwa okunengqondo kanye nomklamo wokucubungula, ama-masterbatches e-PP agcina ilangabi angahlangabezana nezidingo zohlelo lokusebenza ezahlukahlukene.
Ngenxa yemithethonqubo yezemvelo kanye nokuntuleka kokunikezwa kwe-antimony trioxide, inani elikhulayo lamakhasimende lisebenzisa ama-halogen-free phosphorus-nitrogen flame retardants ukuze asetshenziswe njenge-PP masterbatches. Isibonelo,I-TF-241ingasetshenziswa ngqo emikhiqizweni ye-PP kanye nama-masterbatches, ifinyelele imiphumela ezimele yokwakha i-char kanye ne-intumescent ngaphandle kwezithasiselo ezengeziwe. Ukuze kuthuthukiswe izakhiwo zemishini, kunconywa inani elifanele lama-plasticizer kanye nama-coupling agents.
