Mayankho Oletsa Moto a Mafilimu a PET

Mayankho Oletsa Moto a Mafilimu a PET

Kasitomala amapanga mafilimu owoneka bwino a PET omwe amaletsa moto okhala ndi makulidwe kuyambira 0.3 mpaka 1.6 mm, pogwiritsa ntchito hexaphenoxycyclotriphosphazene (HPCTP) ndipo amafuna kuchepetsa ndalama. Pansipa pali njira zomwe zikulimbikitsidwa komanso kusanthula mwatsatanetsatane kwa mafilimu owoneka bwino a PET omwe amaletsa moto:

1. Kusanthula kwa Kusankha Zoletsa Moto

Hexaphenoxycyclotriphosphazene (HPCTP)

• Ubwino: Zoletsa moto zochokera ku Phosphazene zimafalikira bwino mu PET, zomwe zimapangitsa kuti ziwoneke bwino kwambiri. Njira yoletsa moto imaphatikizapo kuyaka kwa magawo ofupikitsidwa komanso kutsekereza kwa magawo a gasi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mafilimu owonekera bwino.
• Mlingo: Woyenera kukhala 5%-10%. Kuchuluka kwambiri kungakhudze momwe makina amagwirira ntchito.
• Mtengo: Wokwera kwambiri, koma mtengo wonse umatha kusinthidwa ngakhale mutanyamula katundu wochepa.

Aluminiyamu Hypophosphite

• Zoyipa: Ufa wosapangidwa ndi zinthu zachilengedwe ungayambitse chifunga, zomwe zimakhudza kuwonekera bwino. Kukula kwa tinthu tating'onoting'ono kwambiri kapena kusintha kwa pamwamba kungafunike kuti mugwiritse ntchito.
• Kugwiritsa ntchito: Sikuvomerezeka kokha; ikhoza kusakanikirana ndi HPCTP kuti muchepetse mtengo wonse (kuyesa kuwonekera bwino kumafunika).

2. Njira Zopangira Zovomerezeka

Njira 1: Dongosolo la HPCTP Limodzi

• Kupanga: 8%-12% HPCTP + PET maziko.
• Ubwino: Kuwonekera bwino komanso kugwira ntchito bwino kwambiri (kungathandize UL94 VTM-2 kapena VTM-0).
• Kuwerengera Mtengo: Pa 10% ya katundu, kuwonjezeka kwa mtengo pa kg iliyonse ya PET kuli pafupifupi ¥10 (¥100/kg × 10%).

Njira yachiwiri: HPCTP + Aluminium Hypophosphite Blend

• Kupanga: 5% HPCTP + 5%-8% aluminiyamu hypophosphite + PET maziko.
• Ubwino: Kuchepetsa mtengo, ndi aluminiyamu hypophosphite yomwe imathandiza kuchepetsa moto wa gasi, zomwe zingachepetse kugwiritsa ntchito HPCTP.
• Dziwani: Kuwonekera kuyenera kuyesedwa (aluminiyamu hypophosphite ingayambitse chifunga pang'ono).

3. Malangizo Okonza ndi Kuyesa

• Njira Yofalitsira: Gwiritsani ntchito chotulutsira cha zingwe ziwiri kuti muwonetsetse kuti zinthu zoletsa moto zikufalikira mofanana komanso kupewa kusonkhana kwa zinthu zomwe zingasokoneze kuwonekera bwino.
• Kuyesa Kubwerera kwa Moto: Yesani motsatira miyezo ya UL94 VTM kapena Oxygen Index (OI), ndikuyang'ana OI > 28%.
• Kuyesa Kuwonekera: Yesani chipale chofewa pogwiritsa ntchito choyezera chipale chofewa, kuonetsetsa kuti chipale chofewa chili < 5% (kukhuthala kwa filimu: 0.3-1.6 mm).

4. Kuyerekeza Mtengo

Kutsegula Kosatha kwa Moto ndi Kukweza Mtengo

5. Mapeto

• Njira Yokondedwa: HPCTP yokha pa 8%-10%, kulinganiza kuwonekera bwino komanso kuchedwa kwa moto.
• Njira ina: Kusakaniza kwa HPCTP ndi aluminium hypophosphite, komwe kumafuna kutsimikizira kuwonekera bwino komanso zotsatira zogwirizana.

Malangizo: Kasitomala ayenera kuchita mayeso ang'onoang'ono kaye, kuyang'ana kwambiri pa kuchedwa kwa moto (UL94/OI) ndi kuyesa nthunzi, kenako kukonza njira yopangira ndi njira. Ngati pakufunika kuchepetsa ndalama zina, fufuzani zinthu zochepetsera moto zopangidwa ndi aluminiyamu kapena zinthu zatsopano zochepetsera moto zopangidwa ndi phosphorous.
