TF-241 Halogen-free ammonium polyphosphate retardant lawi la PP
Mawu Oyamba
Ubwino waukulu wogwiritsa ntchito kuphatikiza APP TF-241 ili ndi chotchingira moto mu polypropylene (PP) ndi motere.Choyamba, TF-241 imalepheretsa kuyaka kwa PP, kukulitsa kukana kwake kwamoto.Izi ndi zofunika kwambiri m'malo omwe chitetezo chamoto chimakhala chofunikira kwambiri.Kachiwiri, TF-241 ali kwambiri matenthedwe bata, kusunga structural umphumphu PP pa kutentha kwambiri.Zimathandizanso kuchepetsa kutulutsa utsi komanso kutulutsa mpweya wapoizoni panthawi yoyaka, kuchepetsa ngozi zomwe zingachitike paumoyo.Kuphatikiza apo, kuyanjana kwa TF-241 ndi PP ndikwabwino kwambiri, kuwonetsetsa kusakanikirana kosavuta komanso kugwira ntchito kosasintha.Ponseponse, kuphatikiza kwa synergistic kwa TF-241 kumawonetsa zabwino zake zazikulu ngati cholepheretsa lawi la PP.

Makhalidwe
1. Ma ion opanda halogen komanso opanda zitsulo zolemera.
2. Kutsika kochepa, kutulutsa utsi wochepa.
2. ufa woyera, kukana madzi abwino, akhoza kudutsa 70 ℃, 168h kumiza mayeso.
3. Kukhazikika kwapamwamba kwa kutentha, ntchito yabwino yopangira, palibe kutsetsereka kwamadzi komwe kumawonekera panthawi yokonza.
4. Kuwonjezeka kwazing'ono, kutentha kwakukulu kwamoto, kupitirira 22% kumatha kudutsa UL94V-0 (3.2mm).
5. Zopangira zoletsa moto zimakhala ndi ntchito yabwino yolimbana ndi kutentha kwambiri ndipo zimatha kupitilira mayeso a GWIT 750 ℃ ndi GWFI 960 ℃.
7. Zowonongeka kukhala phosphorous ndi nayitrogeni mankhwala.
Kugwiritsa ntchito
TF-241 ntchito homopolymerization PP-H ndi copolymerization PP-B ndi HDPE .Amagwiritsidwa ntchito kwambiri mu polyolefin yoletsa moto komanso HDPE monga chotenthetsera mpweya ndi zida zapakhomo.
Njira Yolozera ya 3.2mm PP (UL94 V0):
| Zakuthupi | Fomula S1 | Fomu S2 |
| Homopolymerization PP (H110MA) | 77.3% |
|
| Copolymerization PP (EP300M) |
| 77.3% |
| Mafuta (EBS) | 0.2% | 0.2% |
| Antioxidant (B215) | 0.3% | 0.3% |
| Anti-dripping (FA500H) | 0.2% | 0.2% |
| Mtengo wa TF-241 | 22-24% | 23-25% |
Makina amakina otengera 30% kuwonjezera voliyumu ya TF-241.Ndi 30% TF-241 kufikira UL94 V-0 (1.5mm)
| Kanthu | Fomula S1 | Fomu S2 |
| Kutentha kwamphamvu kwamphamvu | V0 (1.5mm) | UL94 V-0 (1.5mm) |
| Chepetsani index ya okosijeni (%) | 30 | 28 |
| Mphamvu yamagetsi (MPa) | 28 | 23 |
| Elongation panthawi yopuma (%) | 53 | 102 |
| Kutentha kwamoto pambuyo pa madzi owiritsa (70 ℃,48h) | V0 (3.2mm) | V0 (3.2mm) |
| V0 (1.5mm) | V0 (1.5mm) | |
| Flexural modulus (MPa) | 2315 | 1981 |
| Sungunulani index (230 ℃,2.16KG) | 6.5 | 3.2 |
Kulongedza:25kg / thumba, 24mt/20'fcl opanda pallets, 20mt/20'fcl ndi pallets.Kulongedza kwina ngati pempho.
Posungira:m'malo owuma ndi ozizira, osachita chinyezi ndi dzuwa;min.alumali moyo zaka ziwiri.
