Musiyano pakati pechipfu uye pi yemagetsi ekuparadza firimu

Pet uye pi ndivo vaviri substrates yekuparadza yemagetsi firimu. Asi chii musiyano uripo pakati pezvakafanana nemagetsi ekuparadza firimu uye akasiyana simbisa?
Kutanga, ngatitangei nekunzwisisa pet uye pi: Pet Brendwil yeBritish yePolyethyle terephthalate (Pet) kana Petp. Poly (terephthaal acid) plastics inosanganisira poly (ethylene terephthalate) difelone pet uye polylene terephthalate) dilles pbt). Poly (ethylene terephthalate) inowanzo kutaurwa sePolyester resin uye inowanzonzi polyester resin. Icho chidimbu chekuburitsa che terephthalic acid uye ethylene glycol. Pamwe chete nePBT inozivikanwa seTermplastic Polyester kana Polyester.

Polyimide (polyimide), kazhinji anotaurwa sePi muChinese, inyaya yetsika yechiChineseclic Compund ine machinda akaumbwa. Iyo Chirungu zita renhema

Misiyano iri pakati pechipfu uye pi inogona kukamurwa mune inotevera zvinhu zviviri:
Kutanga, kubva pane zvekunze zvekunze: Peleatric kupisa firimu ndeyekupararira kwemagetsi emagetsi ekuparadza firimu, nepo PI yemagetsi inopisa firimu ndeye opaque emagetsi ekuparadza emagetsi ekuparadza firimu.
Chechipiri, musiyano wekudziya-tembiricha yekupisa emagetsi ekuparadza firimu, inogona kutsungirira tembiricha yekudziya kwenguva yakareba, tembiricha yemagetsi yekudziya inogona kusvika 80. Thermostat, tembiricha yemapepa emagetsi ekuparadza firimu iri makumi mashanu + 5C. Pi firimu iri hombe tembiricha yemagetsi inopisa firimu, inogona kushandiswa kwenguva yakareba. Tembiricha inosvika madhigirii 250 Celsius, asi nekuda kwekuchengetedza zvikonzero, iyo yakajairika tembiricha yekuisa pi firimu ndeye 120 + 5 degrees celsius
