Brief Analysis of the Practical Application of Pilem Polimida

pilem Polyimide mangrupakeun salah sahiji komoditi pangheubeulna ngeunaan polyimide, nu dipaké pikeun insulasi slot motor jeung bahan wrapping kabel. Produk utama nyaéta DuPont Kapton, séri Ube’s Upilex sareng Zhongyuan Apical. Film polimida transparan janten master sél surya anu fleksibel. The sails of IKAROS dijieunna tina film polyimide jeung serat. Dina séktor pembangkit listrik termal, serat polyimide tiasa dianggo pikeun nyaring gas panas, sareng benang polyimide tiasa misahkeun lebu sareng bahan Kimia khusus.

Palapis: Salaku cet insulating pikeun kawat magnet, atawa salaku cet tahan suhu luhur.

Advanced composite materials: used in aerospace, aircraft and rocket components. It is one of the most high temperature resistant structural materials. For example, the supersonic passenger plane in the United States is designed to have a speed of 2.4M, a surface temperature of 177°C during flight, and a required service life of 60,000h. It is reported that 50% of the structural materials have been determined to be thermoplastic polyimide as the matrix resin. of carbon fiber reinforced composite materials, the amount of each aircraft is about 30t.

Serat: Modulus élastisitas kadua ukur pikeun serat karbon, anu dianggo salaku bahan saringan pikeun média suhu luhur sareng zat radioaktif, ogé lawon anti peluru sareng seuneu. Rupa-rupa produk polyimide dihasilkeun di Changchun, Cina.

Plastik busa: dipaké salaku bahan insulasi suhu luhur.

Plastik rékayasa: Aya térmosét sareng termoplastik. Thermoplastics tiasa komprési dijieun atawa suntik dijieun atawa mindahkeun dijieun. Utamana dipaké pikeun timer lubricating, sealing, insulating jeung bahan struktural. bahan polyimide Guangcheng geus dilarapkeun ka bagian mékanis kayaning vanes Rotary compressor, cingcin piston jeung anjing laut pompa husus.

Mémbran separation: dipaké pikeun misahkeun rupa pasangan gas, kayaning hidrogén / nitrogén, nitrogén / oksigén, karbon dioksida / nitrogén atawa métana, jsb, pikeun miceun Uap tina hawa gas hidrokarbon feed jeung alkohol. Ogé bisa dipaké salaku mémbran pervaporation sarta mémbran ultrafiltration. Kusabab résistansi panas sareng résistansi pelarut organik tina polyimide, éta penting pisan dina pamisahan gas organik sareng cair.
