Chinhu chinodzivirira moto chisina halogen chakadai seAPP, AHP, MCA chine mabhenefiti makuru kana chikashandiswa mupurasitiki. Chinoshanda sechinhu chinodzivirira moto chinoshanda, chichiwedzera kudzivirira moto kwechinhu chacho. Uyezve, chinobatsira kuvandudza hunhu hwemakemikoro nekupisa kwepurasitiki, zvichiita kuti igare kwenguva refu uye irambe ichidzivirirwa pakupisa kwakanyanya.
PP yepurasitiki inodzivirira moto
Tsananguro yechigadzirwa: TF-241 inonyanya kuva neP neN, imhando yemuto unodzivirira nharaunda usina halogen usingakuvadzi nharaunda wepolyolefin. Yakagadzirwa kunyanya kuitirwaPP dzakasiyana-siyanaTF-241 ine acid source, gasi source uye kabhoni source, inotanga kushanda nekugadzirwa kwechar uye intumescent mechanism.
Zvakanakira:PP inodzivisa moto inorapwa neTF-241 ine simba rekudzivirira mvura zviri nani. Ichiri kushanda zvakanaka mushure mekufashaira kwemaawa makumi manomwe nemaviri mumvura ine tembiricha ye70℃.
PP (3.0-3.2mm) ine 22% TF-241 inogona kupasa bvunzo dzeUL94 V-0 uye GWIT 750℃ / GWFI 960℃.
PP (1.5-1.6mm) ine 30% yekuwedzera TF-241 inogona kupasa bvunzo dzeUL94 V-0.
Pepa reData reUnyanzvi / Tsanangudzo:
| Tsanangudzo | TF-241 |
| Chitarisiko | Upfu chena |
| P2O5zviri mukati (w/w) | ≥52% |
| Zviri mukati meN (w/w) | ≥18% |
| Hunyoro (w/w) | ≤0.5% |
| Kuwanda kwehuwandu | 0.7-0.9 g/cm3 |
| Kupisa Kwekuora | ≥260℃ |
| Avhareji yehukuru hwezvimedu (D)50) | anenge 18µm |
Hunhu:
1. Hupfu chena, hunodzivirira mvura zvakanaka.
2. Kuwanda kwehutsi kwakaderera, kuburitsa utsi kwakaderera.
3. Maion esimbi inorema uye isina halogen.
Kushandiswa:
TF-241 inoshandiswa mu homopolymerization PP-H uye copolymerization PP-B. Inoshandiswa zvakanyanya mu
polyolefin inodzivirira moto yakaita semhepo inodziya nemhepo inopfungaira uye midziyo yemumba.
Fomura Yekunongedzera ye3.2mm PP (UL94 V0):

Kurongedza:25kg/bhegi, 22mt/20'fcl isina mapallet, 17mt/20'fcl ine mapallet. Zvimwe zvekurongedza kana zvakumbirwa.
Kuchengetera:munzvimbo yakaoma uye inotonhorera, ichichengetedza hunyoro nezuva, uye inogara kwenguva refu kwemakore maviri.
