Polypropylene (PP) Flame Retardant Masterbatch ke motsoako o nang le mahloriso a mangata oa li-lake retardant le carrier resin, e sebelisetsoang ho nolofatsa phetoho ea li-lake retardant tsa thepa ea PP. Ka tlase ke tlhaloso le tlhaloso e qaqileng ea PP flame retardant masterbatch:
I. Sebopeho sa Motheo sa Masterbatch ea PP Flame Retardant
- Resin ea mojari: Ka tloaelo PP, ho netefatsa hore e lumellana hantle le thepa ea motheo.
- Sethibela-mollo: Ha e na halogen kapa ha e na halogen, e kgethilwe ho latela ditlhoko.
- Setsebi sa ho kopanya: E eketsa ho lieha ha mollo (mohlala, antimony trioxide).
- Sehatsetsi: E ntlafatsa ho hasana ha lintho tse thibelang malakabe.
- Setlolo: E ntlafatsa ho phalla ha ts'ebetso.
- Sehatsetsi: E thibela ho senyeha ha ts'ebetso.
II. Sebopeho sa Halogenated Flame Retardant PP Masterbatch
Li-halogenated flame retardants (mohlala, brominated) tse kopantsoeng le antimony trioxide li fana ka katleho e phahameng.
Mohlala oa ho qapa:
- Resin ea mojari (PP): 40–50%
- Brominated flame retardant (mohlala, decabromodiphenyl ether kapa brominated polystyrene): 30–40%
- Antimony trioxide (setsoalle): 5–10%
- Sefahla-mofuta (mohlala, boka ba polyethylene): 2–3%
- Setlolo (mohlala, calcium stearate): 1–2%
- Antioxidant (mohlala, 1010 kapa 168): 0.5–1%
Mehato ea ho Sebetsa:
- Kopanya metsoako eohle esale pele ka ho lekana.
- Qhibilihisa motsoako o sebelisang sesebelisoa sa ho ntša likurufu tse peli ebe o li kenya pelletize.
- Laola mocheso oa ho ntša metsi ho 180–220°C.
Litšobotsi:
- Ho lieha ha lelakabe haholo ka ho kenya lintho tse ling ka bongata bo fokolang.
- E ka ntša likhase tse chefo nakong ea ho cha.
- E loketse lits'ebetso tse nang le litlhoko tse tlase tsa tikoloho.
III. Tlhahiso ea PP Masterbatch e se nang mollo e thibelang halogen
Di-retant tse se nang halogen (mohlala, phosphorus-, naetrojene-based, kapa inorganic hydroxides) di mosa tikolohong empa di hloka meroalo e mengata.
Mohlala oa ho qapa:
- Resin ea mojari (PP): 30–40%
- Phosphorus-retardant (mohlala, ammonium polyphosphate APP kapa phosphorus e khubelu): 20–30%
- Ntho e thibelang naetrojene (mohlala, melamine cyanurate MCA): 10–15%
- Magnesium hydroxide kapa aluminium hydroxide: 20–30%
- Sefahla-mofuta (mohlala, boka ba polyethylene): 2–3%
- Setlolo (mohlala, zinki stearate): 1–2%
- Antioxidant (mohlala, 1010 kapa 168): 0.5–1%
Mehato ea ho Sebetsa:
- Kopanya metsoako eohle esale pele ka ho lekana.
- Qhibilihisa motsoako o sebelisang sesebelisoa sa ho ntša likurufu tse peli ebe o li kenya pelletize.
- Laola mocheso oa ho ntša metsi ho 180–210°C.
Litšobotsi:
- E sireletsa tikoloho, ha e na likhase tse chefo nakong ea ho cha.
- Ho jara ho eketsehileng ha di-additi ho ka senya thepa ya mechini.
- E loketse lits'ebetso tse nang le maemo a thata a tikoloho.
IV. Lintlha tsa Bohlokoa Moralong oa Tlhahiso
- Khetho ea ho thibela malakabe: Khetha halogenated kapa halogen e se nang eona ho latela melaoana ea tikoloho le khanyetso e hlokahalang ea malakabe.
- Ho lumellana ha resin ea mojari: E tlameha ho tsamaisana le motheo oa PP ho thibela ho arohana ha likarolo.
- Ho hasana: Dispersants le mafura a etsang bonnete ba hore di-retantants di a ajoa ka ho lekana.
- Mocheso oa ho sebetsa: Qoba mocheso o feteletseng ho thibela ho bola ho sa laoleheng.
- Thepa ea mechini: Mehaho e mengata e eketsang e ka fokotsa ts'ebetso; nahana ka lintho tse tiisang (mohlala, POE kapa EPDM).
V. Litšebeliso tse Tloaelehileng
- Sehlopha sa Halogenated: Matlo a elektroniki, lithapo/likhoele.
- Masterbatch e se nang Halogen: Dikamore tsa kahare tsa dikoloi, thepa ya kaho, dibapadi tsa bana.
VI. Litlhahiso tsa Ntlafatso
- Ntlafatsa ho lieha ha lelakabe: Kopanya lintho tse thibelang tse ngata (mohlala, ho sebelisana ha phosphorus le naetrojene).
- Ntlafatsa thepa ea mechiniKenya di-tougheners (mohlala, POE/EPDM).
- Phokotso ea litšenyehelo: Ntlafatsa dikarolelano tse thibelang mocheso 'me u khethe thepa e theko e tlaase.
Ka moralo o utloahalang le o sebetsang, li-masterbatches tsa PP tse thibelang malakabe li ka fihlela litlhoko tse fapaneng tsa ts'ebeliso.
Ka lebaka la melao ea tikoloho le khaello ea phepelo ea antimony trioxide, palo e ntseng e eketseha ea bareki e ntse e sebelisa li-retardants tsa malakabe tsa phosphorus-nitrogen tse se nang halogen bakeng sa li-masterbatches tsa PP. Mohlala,TF-241e ka sebelisoa ka ho toba ho lihlahisoa tsa PP le li-masterbatches, e fihlella litlamorao tse ikemetseng tsa ho theha char le intumescent ntle le litlatsetso tse ling. Ho ntlafatsa thepa ea mechini, ho khothaletsoa bongata bo loketseng ba li-plasticizer le li-coupling agents.
