Mafomu ePolypropylene (PP) Flame Retardant Masterbatch

Polypropylene (PP) Flame Retardant Masterbatch musanganiswa wezvinodzivirira moto zvakanyanya uye resin inotakura, inoshandiswa kurerutsa shanduko yezvishandiso zvePP zvinodzivirira moto. Pazasi pane tsananguro yakadzama yePP flame retardant masterbatch:

I. Kuumbwa kwekutanga kwePP Flame Retardant Masterbatch

• Resin yekutakura: Kazhinji PP, zvichiita kuti ienderane zvakanaka nezvinhu zvepakutanga.
• Chinodzora moto: Halogened kana halogen isina, yakasarudzwa zvichienderana nezvinodiwa.
• Mubatsiri wekubatana: Inowedzera kunonoka kwemurazvo (semuenzaniso, antimony trioxide).
• Muparadziri: Inovandudza kupararira kwezvinodzivisa moto.
• Mafuta ekuzora: Inowedzera kuyerera kwekugadzirisa.
• Chinosimbisa: Inodzivirira kuora panguva yekugadzirisa.

II. Kuumbwa kweHalogenated Flame Retardant PP Masterbatch

Zvinhu zvinodzora moto zvine halogenated (semuenzaniso, brominated) zvakasanganiswa ne antimony trioxide zvinopa kushanda kwakanaka.

Muenzaniso weKugadzira:

• Resin inotakura zvinhu (PP): 40–50%
• Brominated flame retardant (semuenzaniso, decabromodiphenyl ether kana brominated polystyrene): 30–40%
• Antimony trioxide (synergist): 5–10%
• Muchina wekuparadzanisa (semuenzaniso, wakisi yepolyethylene): 2–3%
• Mafuta ekuzora (semuenzaniso, calcium stearate): 1–2%
• Antioxidant (semuenzaniso, 1010 kana 168): 0.5–1%

Matanho Ekugadzirisa:

1. Sanganisa zvinhu zvose zvakaenzana.
2. Nyungudutsa uchishandisa chinhu chinoburitsa zvinhu zviviri (twin-screw extruder) wobva waisa pelletize.
3. Dzora tembiricha yekuburitsa mvura pa 180–220°C.

Hunhu:

• Kunonoka kwemurazvo kwakanyanya uye kuwedzera kwakaderera.
• Inogona kuburitsa magasi ane chepfu panguva yekutsva.
• Yakakodzera kushandiswa zvisina zvinodiwa zvakanyanya zvakatipoteredza.

III. Kuumbwa kwePP Masterbatch Isina Halogen-Flame Retardant

Zvinhu zvinoderedza halogen (semuenzaniso, phosphorus-, nitrogen-based, kana inorganic hydroxides) zvine hushamwari kune nharaunda asi zvinoda zvinhu zvakawanda.

Muenzaniso weKugadzira:

• Resin inotakura zvinhu (PP): 30–40%
• Chinodzivisa phosphorus (semuenzaniso, ammonium polyphosphate APP kana phosphorus tsvuku): 20–30%
• Chinhu chinodzora nitrogen (semuenzaniso, melamine cyanurate MCA): 10–15%
• Magnesium hydroxide kana aruminiyamu hydroxide: 20–30%
• Muchina wekuparadzanisa (semuenzaniso, wakisi yepolyethylene): 2–3%
• Mafuta ekuzora (semuenzaniso, zinc stearate): 1–2%
• Antioxidant (semuenzaniso, 1010 kana 168): 0.5–1%

Matanho Ekugadzirisa:

1. Sanganisa zvinhu zvose zvakaenzana.
2. Nyungudutsa uchishandisa chinhu chinoburitsa zvinhu zviviri (twin-screw extruder) wobva waisa pelletize.
3. Dzora tembiricha yekuburitsa mvura pa 180–210°C.

Hunhu:

• Inochengetedza nharaunda, haina magasi ane chepfu panguva yekutsva.
• Kuwedzera kwekuwedzera kwekuwedzera kunogona kukanganisa mashandiro emakanika.
• Yakakodzera kushandiswa zvine mwero wakasimba wezvakatipoteredza.

IV. Zvinhu Zvikuru Zvinofanira Kufungwa Nezvekugadzira Fomura

• Sarudzo inodzora moto: Sarudza halogen kana kuti halogen isina zvichibva pakurambwa kwemoto kunodiwa uye mitemo yezvakatipoteredza.
• Kuenderana kweresin yemutakuri: Inofanira kunge ichishanda pamwe chete nePP yepakutanga kudzivirira kuparadzwa.
• Kupararira: Zvinodiridza nemafuta zvinoita kuti zvinhu zvinodiridza zvinhu zvipararire zvakaenzana.
• Kugadzira tembiricha: Dzivisa kupisa kwakanyanya kudzivirira kuora kusingadzoreki.
• Hunhu hwemakanika: Kuwedzerwa kwakawanda kwezvinowedzera kunogona kuderedza mashandiro; funga nezvezvinhu zvinosimbisa (semuenzaniso, POE kana EPDM).

V. Mashandisirwo Akajairika

• Halogenated masterbatch: Masheya emagetsi, waya/tambo.
• Masterbatch isina Halogen: Zvemukati memotokari, zvinhu zvekuvaka, matoyi evana.

VI. Mazano ekugadzirisa

• Wedzera kunonoka kwemurazvo: Sanganisa zvinhu zvinoderedza simba (semuenzaniso, phosphorus-nitrogen synergy).
• Kuvandudza hunhu hwemakanikaWedzera zvinosimbisa (semuenzaniso, POE/EPDM).
• Kuderedzwa kwemitengo: Gadzirisa huwandu hwezvinhu zvinodzora simba uye sarudza zvinhu zvinodhura zvishoma.

Nekugadzira zvine musoro uye dhizaini yekugadzirisa, PP flame retardant masterbatches inogona kusangana nezvinodiwa zvakasiyana-siyana zvekushandisa.
Nekuda kwemitemo yezvakatipoteredza uye kushomeka kwe antimony trioxide, nhamba iri kuramba ichikwira yevatengi vari kushandisa halogen-free phosphorus-nitrogen flame retardants kuti vashandise PP masterbatches. Semuenzaniso,TF-241inogona kushandiswa zvakananga kuzvigadzirwa zvePP uye masterbatches, zvichiita kuti pave nemhedzisiro yakazvimiririra yekugadzira char uye intumescent pasina zvimwe zvinowedzera. Kuti zviwedzere kunaka kwemuchina, huwandu hwakakodzera hwemapurasitiki uye ma coupling agents anokurudzirwa.
