Polyimide pi machining chikamu

Polyimide ndiyo molecular chimiro chine hunyanzvi hwekuzvishora polymer compound ) mapoka mana.

Pi parizvino pane mhando dzakanakisa dzeinjiniya mapurasitiki ekupisa kupesana, mamwe marudzi anogona kumira kwenguva refu guva remakore 290 -269 ℃ Liquid Felium haizove brittle. Mukuwedzera, manhamba ekudzivirira, murazvo unopera simba, mishonga inodzora, kuumbwa kwemafuta, general solids. Uye pi haina chepfu, inogona kushandiswa kugadzira tafura yekugadzira uye zvekurapa, uye zvakarambidza zviuru zvevakwana sterilization.

Pi Moding Nzira Dzinosanganisira Kudzvinyirira Kuumba, Kukwirisa, Kuwedzeredza kuumbwa, Kufa Kanda, Kucheka, Kukanda, Kupotsa, uye kufambisa, uye kuendesa kuumbwa.

Nhoroondo yeKubatsiro

Polyimide (PI), akatanga kuoneka muna 1955 edwds uye gomba raGobon, muna 1961 Duponty akagadzira poly (tetremethyle tetracarcarboycarcarboycarcarboylic acid) imsi pamusika pasi pezita reKapton. 1972 Motors yakaitika yakatanga kutsvagisa uye kuvandudza kwePolyetherimide (PEI) muUnited States, uye muna 1982, matani gumi ematani ekugadzira zvikamu zvakavakirwa pasi pezita rekutengeserana. Mushure meizvozvo, Japan Ube maindasitiri, Mitsui Company Company uye dzimwe nyika dzeEurope dzakaona kugadzirwa kwekutengeserana kwePolyimide. Parizvino, polyimide ine marudzi anopfuura makumi maviri, United States, Europe neJapan, vanopfuura makumi mana vagadziri. South Korea, Malaysia, Russia neChina vane nhamba shoma yevarigadziri mukugadzirwa uye kushandiswa kwePolyimide. 2005, kugadzirwa kwepasi rose kwematani zviuru makumi matanhatu, izvo, China akaverengera kwematani zviuru zvishanu.

Application

Pi ane zvikumbiro muAviation, mota, mauto ezvemagetsi uye zvemagetsi michina Semigwagwa yeMotokari, Eute magiya mune indasitiri yemichina, uye inogona kushandiswawo muindasitiri yemotokari. High tembiricha yekuzvinyudza-commessor uye piston muchina, chisimbiso chivharo, michina inopisa nhoo, dzakaparara, etc ..

Polyetherimide ine zvinhu zvakanakisa zvine zvivakwa, zvemagetsi zvinokonzeresa, zvakakwirira uye zvakaderera kudziya, kuzvidzivirira, kuyerera kuyerera, kuumbwa kuyerera kwe010% ~ 0.7%. PEI inogona kuve jekiseni uye yekuumbwa kuumbwa, kugadzirisa kuri nyore, kunogona kuinamatira nzira dzakasiyana siyana uye zvimwe zvigadzirwa, erospace, emagetsi, midziyo yemotokari uye mamwe maindasitiri anoshandiswa zvakanyanya. GE ndiye mugadziri mukuru wepasi rose, uye mamwe mainjiniya ekugezesa exthifices yekugera kuti ape pei alloys uye zvimwe zvigadzirwa zvakagadziridzwa. Maitiro ekuvandudza ndiyo yekutanga kweP-phenylenteentiediamine dhizaini kana nedzimwe nyanzvi yeinjiniya engineering purassics alloy kuti uvandudze kupisa kwayo kupisa; kana nePC, PA uye mamwe mainjiniya mapurasitiki ehukama kuti azivise simba rayo rechanes.

Polyamide-Imide Simba parizvino parizvino isiri yepurasitiki yepurasitiki, iyi ruvara rwemavara idiki Simba re190mpa, gadzira simba re 250mpa. 1.8mpa mutoro kupisa kukanganisa kwekushisa kwe 274 ℃. Pai ane hurukuro yakanaka yekuparadzira uye yakanyanya kupisa, yakakwira frequency pasi peiyo Electromagnetic Properties yesimbi uye zvimwe zvigadzirwa zvine zvivakwa zvakanaka. Inonyanya kushandiswa maGears, maRellers, fani uye kupatsanura mangopa emapaipi, etc. Inogona zvakare kushandiswa seyakagadziriswa zvinyorwa, zvinonyangadza uye zvinhu zvakarongeka.
