Mayankho a Flame Retardant a Makanema a Mapepala a PET

Mayankho a Flame Retardant a Makanema a Mapepala a PET

Makasitomala amapanga makanema owoneka bwino amtundu wa PET osayaka moto okhala ndi makulidwe kuyambira 0.3 mpaka 1.6 mm, pogwiritsa ntchito hexaphenoxycyclotriphosphazene (HPCTP) ndipo amafuna kuchepetsa mtengo. M'munsimu muli makonzedwe ovomerezeka ndi kusanthula mwatsatanetsatane kwa mafilimu owonekera oletsa moto a PET:

1. Kusanthula kwa Kusankhidwa Kwa Flame Retardant

Hexaphenoxycyclotriphosphazene (HPCTP)

• Ubwino: Zotsalira zamoto zochokera ku phosphazene zimabalalika bwino ku PET, kusunga kuwonekera kwambiri. Makina oletsa moto amaphatikizanso kuwotcha kwapang'onopang'ono komanso kukopera kwamphamvu kwa gasi, kupangitsa kuti ikhale yoyenera mafilimu owonekera.
• Mlingo: Akulimbikitsidwa pa 5% -10%. Kuchulukitsitsa kungakhudze makina.
• Mtengo: Ndiwokwera kwambiri, koma mtengo wake wonse umakhala wokhoza kuyendetsedwa pakatundu wocheperako.

Aluminium Hypophosphite

• Kuipa: Ufa wosakhazikika ukhoza kuyambitsa chifunga, kusokoneza kuwonekera. Kukula kwa tinthu tating'ono kwambiri kapena kusinthidwa kwapamwamba kungafunike kuti mugwiritse ntchito.
• Kugwiritsa ntchito: Osavomerezeka yekha; ikhoza kuphatikizidwa ndi HPCTP kuti muchepetse mtengo wonse (kuyesa kuwonekera kumafunika).

2. Njira Zopangira Zopangira

Njira 1: Single HPCTP System

• Kupanga: 8% -12% HPCTP + PET maziko azinthu.
• Ubwino: Kuwonekera bwino bwino komanso kusagwira bwino ntchito kwamoto (kutha kukwaniritsa UL94 VTM-2 kapena VTM-0).
• Kuyerekeza Mtengo: Pakutsitsa 10%, kukweza mtengo pa kg ya PET kuli pafupifupi ¥10 (¥100/kg × 10%).

Njira 2: HPCTP + Aluminium Hypophosphite Blend

• Kupanga: 5% HPCTP + 5% -8% aluminium hypophosphite + PET maziko a zinthu.
• Ubwino: Kuchepetsa mtengo, ndi aluminiyumu hypophosphite yothandiza pakuchepetsa mphamvu yamoto, zomwe zitha kuchepetsa kugwiritsa ntchito HPCTP.
• Chidziwitso: Kuwonekera kuyenera kuyesedwa (aluminium hypophosphite ikhoza kuyambitsa chifunga pang'ono).

3. Kukonzekera ndi Kuyesa Malangizo

• Njira Yobalalitsira: Gwiritsani ntchito chowonjezera chawiri-screw kuti muwonetsetse kubalalitsidwa yunifolomu ya zoletsa moto komanso kupewa kuphatikizika komwe kumakhudza kuwonekera.
• Kuyeza kwa Kubwereranso kwa Flame: Unikani molingana ndi miyezo ya UL94 VTM kapena Oxygen Index (OI), kulunjika OI> 28%.
• Kuyesa Kuwonekera: Yesani chifunga pogwiritsa ntchito mita ya haze, kuonetsetsa kuti chifunga chikhale <5% (makina a filimu: 0.3-1.6 mm).

4. Kuyerekeza Mtengo

5. Mapeto

• Njira Yokondedwa: HPCTP yokha pa 8% -10%, kusanja kuwonekera ndi kuchedwa kwamoto.
• Njira ina: Kuphatikiza kwa HPCTP ndi aluminium hypophosphite, yomwe imafuna kutsimikizika kwa kuwonekera ndi zotsatira za synergistic.

Malangizo: Makasitomala ayambe kuyesa pang'ono pang'ono, kuyang'ana kwambiri kuchedwa kwa malawi (UL94/OI) ndi kuyezetsa chifunga, ndiyeno kukhathamiritsa kapangidwe ndi kachitidwe. Ngati pakufunikanso kuchepetsa mtengo, fufuzani zosinthidwa za aluminiyamu hypophosphite kapena zolemba zatsopano za phosphorous-based flame retardants.
