Polypropylene (PP) Flame Retardant Masterbatch ke motsoako o phahameng oa concentration oa li-flame retardants le carrier resin, tse sebelisetsoang ho nolofatsa phetoho e thibelang mollo ea thepa ea PP. Ka tlase ke tlhahiso le tlhaloso e qaqileng ea PP flame retardant masterbatch:
I. Sebopeho sa Motheo sa PP Flame Retardant Masterbatch
- Resin ea thepa: Ka tloaelo PP, ho netefatsa hore e lumellana hantle le thepa ea motheo.
- E thibelang lelakabe: Halogenated kapa halogen-free, e khethiloeng ho latela litlhoko.
- Setsebi sa Synergist: E matlafatsa ho lieha ha lelakabe (mohlala, antimony trioxide).
- Ea qhalaneng: E ntlafatsa ho hasana ha li-flame retardants.
- Setlolo: E matlafatsa ho sebetsa ha metsi.
- Setsibotsi: E thibela ho senyeha nakong ea ts'ebetso.
II. Halogenated Flame Retardant PP Masterbatch Formulation
Li-halogenated flame retardants (mohlala, brominated) li kopantsoe le antimony trioxide li fana ka ts'ebetso e phahameng.
Tlhahiso ea Mohlala:
- Resin ea Carrier (PP): 40-50%
- Brominated flame retardant (mohlala, decabromodiphenyl ether kapa brominated polystyrene): 30–40%
- Antimony trioxide (synergist): 5-10%
- Dispersant (mohlala, boka ba polyethylene): 2-3%
- Lubricant (mohlala, calcium stearate): 1–2%
- Antioxidant (mohlala, 1010 kapa 168): 0.5–1%
Mehato ea Ts'ebetso:
- Pele ho kopanya likarolo tsohle ka mokhoa o ts'oanang.
- Qhibiliha ka ho sebelisa twin-screw extruder le pelletize.
- Laola mocheso oa extrusion ho 180-220°C.
Litšobotsi:
- Ho lieha ho hoholo ha lelakabe ho nang le litlatsetso tse tlase.
- E ka ntša likhase tse chefo nakong ea mollo.
- E loketse likopo tse nang le litlhoko tse tlase tsa tikoloho.
III. Halogen-Free Flame Retardant PP Masterbatch Formulation
Li-retardants tse se nang halogen (mohlala, phosphorus-, nitrogen-based, kapa inorganic hydroxides) li sebetsa hantle le tikoloho empa li hloka ho jarolloa ho holimo.
Tlhahiso ea Mohlala:
- Resin ea Carrier (PP): 30-40%
- Phosphorus-based retardant (mohlala, ammonium polyphosphate APP kapa phosphorus e khubelu): 20-30%
- Nitrogen-based retardant (mohlala, melamine cyanrate MCA): 10-15%
- Magnesium hydroxide kapa aluminium hydroxide: 20-30%
- Dispersant (mohlala, boka ba polyethylene): 2-3%
- Lubricant (mohlala, zinki stearate): 1–2%
- Antioxidant (mohlala, 1010 kapa 168): 0.5–1%
Mehato ea Ts'ebetso:
- Pele ho kopanya likarolo tsohle ka mokhoa o ts'oanang.
- Qhibiliha ka ho sebelisa twin-screw extruder le pelletize.
- Laola mocheso oa extrusion ho 180-210°C.
Litšobotsi:
- Eco-friendly, ha ho na likhase tse chefo nakong ea mollo.
- Ho kenya li-additive tse holimo ho ka senya thepa ea mochini.
- E loketse likopo tse nang le maemo a thata a tikoloho.
IV. Lintlha Tse ka Sehloohong Moetsong oa Tlhahiso
- Khetho ea ho thibela malakabe: Khetha halogenated kapa halogen-free ho ipapisitse le ho hanyetsa lelakabe ho hlokahalang le melaoana ea tikoloho.
- Tšebelisano ea resin ea Carrier: E tlameha ho lumellana le base PP ho thibela delamination.
- Phasano: Li- dispersants le lubricant li netefatsa kabo e tšoanang ea li-retardants.
- Mocheso oa ho sebetsa: Qoba mocheso o feteletseng ho thibela ho bola ho sa feleng.
- Thepa ea mechine: Lisebelisoa tse phahameng tsa tlatsetso li ka theola ts'ebetso; nahana ka li-toughening agents (mohlala, POE kapa EPDM).
V. Likopo tse Tloaelehileng
- Halogenated masterbatch: Matlo a elektronike, lithapo/lithapo.
- Masterbatch e se nang Halogen: Likahare tsa likoloi, thepa ea kaho, lipapali tsa bana.
VI. Litlhahiso tsa ho ntlafatsa
- Ntlafatsa ho lieha ha lelakabe: Kopanya li-retardants tse ngata (mohlala, phosphorus-nitrogen synergy).
- Ntlafatsa thepa ea mochini: Eketsa li-tougheners (mohlala, POE/EPDM).
- Phokotso ea litšenyehelo: Ntlafatsa likarohano tse retardant 'me u khethe lisebelisoa tse baballang chelete e ngata.
Ka moralo o hlophisitsoeng le moralo oa ts'ebetso, li-masterbatches tsa PP tse thibelang malakabe li ka fihlela litlhoko tse fapaneng tsa kopo.
Ka lebaka la melaoana ea tikoloho le khaello ea phepelo ea antimony trioxide, palo e ntseng e eketseha ea bareki e amohela li-halogen-free phosphorus-nitrogen flame retardants bakeng sa li-masterbatches tsa PP. Mohlala,TF-241e ka sebelisoa ka kotloloho ho lihlahisoa tsa PP le li-masterbatches, ho fihlela litlamorao tse ikemetseng tsa char-forming le intumescent ntle le li-additives tse ling. Ho ntlafatsa thepa ea mochini, ho khothaletsoa palo e nepahetseng ea li-plasticizers le li-coupling agents.
