Polyacrylonitrile/PAN/CAS:25014-41-9

Kufotokozera:

Polyacrylonitrile ndi mtundu wa utomoni wopangidwa ndi acrylonitrile womwe umapangidwa kudzera mu free radical polymerization. Ndi wa banja la acrylic resin. Ndi thermoplastic, ndipo umalimbana ndi zosungunulira ndi mankhwala ambiri chifukwa cha ma chemical bonds amphamvu omwe amapangidwa pakati pa magulu a nitrile. Ndi mtundu wa polima wosinthasintha womwe ungagwiritsidwe ntchito kupanga mitundu yambiri ya zinthu monga ulusi wa nsalu, ultra filtration membrane, carbon fiber ndi hollow fibers for reverse osmosis. Homopolymer yake ingagwiritsidwenso ntchito ngati ulusi m'ma awning akunja, ma sail a yachts, ndi fiber-reinforced konkire. Ingagwiritsidwenso ntchito popanga nsalu zosagwirizana ndi moto (FR).

Kagwiritsidwe Ntchito

Chifukwa cha makhalidwe ake apadera monga kukhazikika pa kuwonongeka kwa UV, kuchepa kwa kachulukidwe, mphamvu yayikulu komanso kusinthasintha kwa kutentha, kukhazikika kwa kutentha, kusasinthasintha komanso kukana mankhwala, Polyacrylonitrile ndi polima wofunikira kwambiri pa ntchito zosiyanasiyana. Chifukwa chake, imagwiritsidwa ntchito popanga nsalu chifukwa cha mawonekedwe ake ofanana ndi ubweya, popanga ulusi wa kaboni, ma nembanemba osefera, ulusi wolimbitsa simenti, ma sail a ma yacht, nsalu zotchingira padenga pa ntchito zakunja, ulusi wapadera woteteza kutentha ndi kutentha, ulusi woletsa moto komanso popanga ma felt a machitidwe osefera mpweya wotentha.
Ma copolymer okhala ndi polyacrylonitrile, omwe safuna kuyaka moto, amagwiritsidwa ntchito ngati ulusi popanga zovala zolukidwa, monga masokosi ndi majuzi, komanso zinthu zakunja monga mahema. Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) ndi Poly(styrene-co-acrylonitrile)(SAN) amagwiritsidwa ntchito ngati pulasitiki. ABS ndi polima yopepuka komanso yamphamvu kwambiri. Ndi yopepuka komanso yolimba mokwanira kuti igwiritsidwe ntchito popanga ziwalo za thupi la galimoto. Chifukwa chake, izi zimapangitsa magalimoto kukhala opepuka pogwiritsa ntchito mafuta ochepa motero kuipitsa pang'ono.
Mphamvu ya ABS imachokera ku magulu a nitrile omwe amapezeka m'mayunitsi ake a acrylonitrile. Magulu a nitrile ndi a polar kwambiri; motero, amatha kukopeka wina ndi mnzake. Izi zimapangitsa kuti magulu a nitrile azitha kukhazikika. Kukopa kwamphamvu kumeneku kumagwirira unyolo wa ABS mwamphamvu kwambiri, motero, kumapangitsa kuti chinthucho chikhale cholimba kwambiri. Kuphatikiza apo, polybutadiene ya rabara yomwe ili mkati mwake imapangitsa ABS kukhala polima yolimba.

Kulongedza ndi Kutumiza

25KG/Chikwama kapena malinga ndi zosowa za makasitomala.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
