I-Polypropylene (PP) I-Flame Retardant Masterbatch iifom yesalathiso

I-Polypropylene (PP) I-Flame Retardant Masterbatch ngumxube ophezulu we-concentration we-flame retardants kunye ne-carrier resin, esetyenziselwa ukwenza lula ukuguqulwa kwe-flame-retardant yezinto ze-PP. Apha ngezantsi kukho iinkcukacha zePP flame retardant masterbatch kunye nengcaciso:

I. Ulwakhiwo olusisiseko lwePP Flame Retardant Masterbatch

• I-resin ye-Carrier: Ngokuqhelekileyo iPP, iqinisekisa ukuhambelana kakuhle kunye nesiseko sezinto.
• Iretadant yomlilo: I-Halogenated okanye i-halogen-free, ikhethwe ngokusekelwe kwiimfuno.
• I-Synergist: Yongeza ukulibaziseka komlilo (umzekelo, i-antimony trioxide).
• Ukuchithachitha: Iphucula ukusasazwa kweeretadants zomlilo.
• Isithambiso: Yandisa ukusetyenzwa kwamanzi.
• Isizinzi: Inqanda ukuthotywa ngexesha lokulungiswa.

II. IHalogenated Flame Retardant PP Masterbatch Formulation

IHalogenated flame retardants (umz., brominated) idityaniswe ne-antimony trioxide inika ukusebenza kakuhle okuphezulu.

Ukuqulunqwa koMzekelo:

• I-Carrier resin (PP): 40-50%
• I-Brominated flame retardant (umz., i-decabromodiphenyl ether okanye i-brominated polystyrene): 30–40%
• I-Antimony trioxide (i-synergist): 5–10%
• I-Disperant (umzekelo, i-polyethylene wax): 2-3%
• I-Lubricant (umz., i-calcium stearate): 1–2%
• I-Antioxidant (umzekelo, i-1010 okanye i-168): 0.5-1%

Amanyathelo okucubungula:

1. Hlanganisa onke amacandelo ngokulinganayo kwangaphambili.
2. Nyibilikisa-udibanise usebenzisa i-twin-screw extruder kunye ne-peltize.
3. Lawula iqondo lobushushu le-extrusion kwi-180–220°C.

Iimpawu:

• Ukubuyiswa komlilo ophezulu kunye nokulayishwa okuphantsi kokongeza.
• Ingakhupha iigesi eziyityhefu ngexesha lokutsha.
• Ifanelekile kwizicelo ezineemfuno eziphantsi zokusingqongileyo.

III. Halogen-Free Flame Retardant PP Masterbatch Formulation

I-halogen-free retardants (umzekelo, i-phosphorus-, i-nitrogen-based, okanye i-inorganic hydroxides) i-eco-friendly kodwa ifuna ukulayisha okuphezulu.

Ukuqulunqwa koMzekelo:

• I-Carrier resin (PP): 30-40%
• I-phosphorus-based retardant (umzekelo, i-ammonium polyphosphate APP okanye i-phosphorus ebomvu): 20-30%
• I-Nitrogen-based retardant (umzekelo, i-melamine cyanrate MCA): 10-15%
• I-Magnesium hydroxide okanye i-aluminium hydroxide: 20-30%
• I-Disperant (umzekelo, i-polyethylene wax): 2-3%
• I-Lubricant (umz., i-zinc stearate): 1–2%
• I-Antioxidant (umzekelo, i-1010 okanye i-168): 0.5-1%

Amanyathelo okucubungula:

1. Hlanganisa onke amacandelo ngokulinganayo kwangaphambili.
2. Nyibilikisa-udibanise usebenzisa i-twin-screw extruder kunye ne-peltize.
3. Lawula iqondo lobushushu le-extrusion kwi-180–210°C.

Iimpawu:

• I-Eco-friendly, akukho gesi ezinetyhefu ngexesha lokutsha.
• Ukulayisha okuphezulu okongeziweyo kunokuphazamisa iimpawu zoomatshini.
• Ifanelekile kwizicelo ezinemigangatho engqongqo yokusingqongileyo.

IV. Iingqwalasela eziphambili kuYilo loYilo

• Ukukhetha i-flame retardant: Khetha i-halogenated okanye i-halogen-free ngokusekelwe ekuxhathiseni ilangatye elifunekayo kunye nemimiselo yokusingqongileyo.
• Ukuhambelana kwe-resin ye-Carrier: Kufuneka ihambelane nesiseko se-PP ukunqanda i-delamination.
• Ukusasazwa: Izisasazi kunye nezithambiso ziqinisekisa ukuhanjiswa okufanayo kweeretadants.
• Ukulungiswa kobushushu: Kuphephe ubushushu obugqithileyo ukunqanda ukubola okungalawulekiyo.
• Iimpawu zoomatshini: Ukulayisha okuphezulu okongeziweyo kunokuthoba ukusebenza; qwalasela ii-agent eziqinisayo (umzekelo, i-POE okanye i-EPDM).

V. IiNkqubo eziQhelekileyo

• Halogenated masterbatch: Izindlu zombane, iingcingo/iintambo.
• Halogen-free masterbatch: Izinto zangaphakathi zeemoto, izinto zokwakha, izinto zokudlala zabantwana.

VI. Iingcebiso zoPhuculo

• Ukwandisa ukulibaziseka komlilo: Dibanisa iiretardants ezininzi (umzekelo, i-phosphorus-nitrogen synergy).
• Ukuphucula iimpawu zoomatshini: Yongeza i-tougheners (umzekelo, i-POE / EPDM).
• Ukunciphisa iindleko: Lungiselela ulungelelwaniso lwe-retardant kwaye ukhethe izinto ezingabizi kakhulu.

Ngokuqulunqwa okunengqiqo kunye noyilo lokucubungula, ii-masterbatches ze-PP flame retardant zinokuhlangabezana neemfuno ezahlukeneyo zesicelo.
Ngenxa yemimiselo yokusingqongileyo kunye nokunqongophala konikezelo lwe-antimony trioxide, inani elandayo labathengi bamkela i-halogen-free phosphorus-nitrogen retardants yeflame ye-PP masterbatches. Njengokuba,TF-241ingasetyenziswa ngokuthe ngqo kwiimveliso zePP kunye ne-masterbatches, ukufezekisa i-char-forming ezimeleyo kunye nemiphumo ye-intumescent ngaphandle kwezongezo ezongezelelweyo. Ukwandisa iipropathi zoomatshini, izixa ezifanelekileyo zeeplasticizers kunye neearhente zokudibanisa ziyacetyiswa.
