Special engineering mapurasitiki anoreva mapurasitiki einjiniya ane yakakwirira yakazara zvivakwa uye tembiricha yenguva refu yebasa iri pamusoro pe150 ℃. Kazhinji ese ari maviri epamusoro tembiricha kuramba, nemwaranzi kuramba, hydrolysis kuramba, mamiriro ekunze, corrosion resistance, natural flame retardant, low thermal kuwedzera mwero, kuneta kuramba uye zvimwe zvakanakira. Kune akawanda marudzi eakakosha einjiniya mapurasitiki, anosanganisira polyliquid crystal polymer (LCP), polyether ether ketone (PEEK), polyimide (PI), phenyl sulfide (PPS), polysulfone (PSF), polyaromatic ester (PAR), fluoropolymers (PTFE, PVDF, PCTFE, PFA), nezvimwewo.
Kubva pakuona kwenhoroondo uye mamiriro ezvinhu aripo, nyika dzeEurope neAmerica kubva pakuuya kwepolyimide muma1960 uye nekuuya kwepolyether ether ketone mukutanga kwema1980, kusvika ikozvino yakagadzira marudzi anopfuura gumi einjiniya mapurasitiki maindasitiri. China yakakosha mainjiniya mapurasitiki akatanga pakati uye mukupera kwema1990. Parizvino, iyo indasitiri iri mudanho rekutanga rebudiriro, asi kukurumidza kwekusimudzira kuri kukurumidza. Akawanda akajairika einjiniya mapurasitiki anotorwa semuenzaniso.
Liquid crystal polymer (LCP) imhando yezvinonhuhwirira zvepolyester ine huwandu hukuru hweyakaomarara benzene mhete pacheni huru, iyo inozochinja kuita yemvura fomu yekristaro pasi peimwe nyika yekudziya, uye ine yakanakisa kunzwisisika zvinhu. Parizvino, huwandu hwepasi rose hwekristaro hwepolymer hunosvika 80,000 matani / gore, uye United States neJapan dzinotora 80% yehuwandu hwepasi rose. Indasitiri yekuChina yeLCP yakatanga kunonoka, iine huwandu hwazvino hwekugadzira hunosvika zviuru makumi maviri zvematani / gore. Vagadziri vakuru vanosanganisira Shenzhen Water New Materials, Zhuhai Vantone, Shanghai Puliter, Ningbo Jujia, Jiangmen Dezotye, etc. Zvinotarisirwa kuti kushandiswa kwese kweLCP kuchachengetedza kukura kwe6% uye kudarika 40,000 matani muna 2025, inotungamirirwa. nekudiwa kwemidziyo yemagetsi nemagetsi uye zvikamu zvemotokari.
Polyether ether ketone (PEEK) ndeye semi-crystalline, thermoplastic inonhuhwirira polymer zvinhu. Parizvino, kune marudzi matatu e polyether ether ketone pamusika: pure resin, girazi fiber yakagadziridzwa, kabhoni fiber yakagadziridzwa. Parizvino, Wiggs ndiyo inogadzira pasi rose yepolyether ketone, ine simba rekugadzira rinosvika 7000 matani / gore, inoverengera inosvika 60% yehuwandu hwepasi rose. Kuvandudzwa kwetekinoroji yePOLYEther ether ketone muChina kwakatanga kunonoka, uye huwandu hwekugadzira hwakanyanya kuiswa muZhongyan, Zhejiang Pengfu Long uye Jida Te Plastics, inoverengera makumi masere muzana ehuwandu hwekugadzira huwandu muChina. Zvinotarisirwa kuti mumakore mashanu anotevera, kudiwa kwePEEK muChina kuchachengetedza chiyero chekukura che15% ~ 20% uye kusvika 3000 matani muna 2025.
Polyimide (PI) inonhuhwirira heterocyclic polymer compound ine imide mhete mucheni huru. Makumi manomwe muzana ekugadzirwa kwePI kwepasirese kuri muUnited States, Japan, South Korea nedzimwe nyika. PI firimu rinozivikanwawo se "goridhe firimu" nekuda kwekuita kwayo kwakanaka. Parizvino, kune vanenge makumi manomwe vanogadzira mafirimu epolyimide muChina, vane hunyanzvi hwekugadzira hunosvika zana rematani. Izvo zvinonyanya kushandiswa mumusika wakaderera, nepo iyo yakazvimirira yekutsvagisa uye yekusimudzira nhanho yezvigadzirwa zvepamusoro-soro haina kukwirira, uye inonyanya kutengwa kunze kwenyika.
PPS ndeimwe yemhando dzakakosha uye dzakajairika dze polyaryl sulfide resins. PPS ine yakanakisa kupisa kwekuita, kuita kwemagetsi, makemikari kuramba, nemwaranzi kuramba, retardant murazvo uye zvimwe zvivakwa. PPS ndeye thermoplastic yakakosha mainjiniya epurasitiki ine yakanakisa dhizaini kuita uye yakakwirira mutengo kuita. PPS inowanzo shandiswa seyakarongeka polymer zvinhu. Inoshandiswa zvakanyanya mumotokari, zvemagetsi nemagetsi, makemikari, michina, aerospace, indasitiri yenyukireya, chikafu uye zvinodhaka indasitiri uye mamwe minda.
Kubva mundima yekunyorera, mapurasitiki einjiniya akakosha mukuwedzera kukushandisa mune zvemagetsi, mota, aerospace, zviridzwa zvakaringana, nedzimwe nzvimbo dzechinyakare, ine 5 g kutaurirana, mota nyowani dzesimba, high pressure yekubatanidza, zvemagetsi zvevatengi, semiconductor, hutano, simba. uye mamwe maindasitiri, nekukurumidza kukura kwekushandiswa kweakakosha einjiniya mapurasitiki ari kuwedzerawo, huwandu uye rudzi rwekushandisa zviri kukwira.
Kubva pakati pe-rukova shanduko uye kugadzirisa, akakosha einjiniya mapurasitiki anowanzo kugadziridzwa negirazi/carbon fiber reinforcement, toughening, mineral filling, antistatic, lubrication, dyeing, kupfeka kuramba, kusanganisa alloy, nezvimwewo, kuti vawedzere kuwedzera kukosha kwekushandisa kwavo. . Maitiro ayo ekugadzirisa uye epashure-ekugadzirisa anosanganisira kusanganisa gadziriso, jekiseni kuumba, extrusion firimu, impregnation composite, bar profiles, mechanic process, iyo inoshandisa akasiyana ekuwedzera, kugadzira michina, nezvimwe.
