Iiplastiki zobunjineli ezikhethekileyo zibhekisa kwiiplastiki zobunjineli ezineempawu eziphezulu ezibanzi kunye nobushushu benkonzo yexesha elide ngaphezulu kwe-150 ℃. Ngokubanzi zombini ukuxhathisa ubushushu obuphezulu, ukuxhathisa kwimitha, ukuxhathisa i-hydrolysis, ukuxhathisa imozulu, ukuxhathisa umhlwa, ukubuyiswa komlilo wendalo, izinga eliphantsi lokwanda kwe-thermal, ukuxhathisa ukudinwa kunye nezinye iingenelo. Kukho iintlobo ezininzi zeeplastiki zobunjineli ezikhethekileyo, kuquka i-polyliquid crystal polymer (LCP), i-polyether ether ketone (PEEK), i-polyimide (PI), i-phenyl sulfide (PPS), i-polysulfone (PSF), i-polyaromatic ester (PAR), i-fluoropolymers (PTFE, PVDF, PCTFE, PFA), njl.
Ukususela kumbono wembali kunye nemeko yangoku, amazwe aseYurophu naseMelika ukususela ekufikeni kwe-polyimide kwiminyaka ye-1960 kunye nokufika kwe-polyether ether ketone ekuqaleni kwe-1980s, ukuza kuthi ga ngoku kuye kwaqulunqa iintlobo ezingaphezu kwe-10 zobunjineli obukhethekileyo beplastiki ye-industrialization. Iiplastiki zobunjineli ezikhethekileyo zaseTshayina zaqala phakathi nasekupheleni kweminyaka yoo-1990. Okwangoku, ishishini likwinqanaba lokuqala lophuhliso, kodwa isantya sophuhliso sikhawuleza. Iiplastiki ezikhethekileyo zobunjineli ezininzi eziqhelekileyo zithathwa njengemizekelo.
I-Liquid crystal polymer (LCP) luhlobo lwemathiriyeli enevumba elimnandi yepolyester equlethe inani elikhulu lolwakhiwo lwerigid benzene yeringi kumxokelelwane oyintloko, onokuthi utshintshe ube yikristale engamanzi phantsi kobushushu obuthile, kwaye ineempawu ezigqwesileyo. Okwangoku, umthamo wehlabathi we-crystal polymer elulwelo malunga neetoni ezingama-80,000 ngonyaka, kwaye i-United States neJapan zithatha malunga ne-80% yomthamo wehlabathi. Ushishino lwaseTshayina lwe-LCP luqale emva kwexesha, kunye nomthamo okhoyo wemveliso omalunga neetoni ezingama-20,000 ngonyaka. Abavelisi abakhulu baquka i-Shenzhen Water New Materials, i-Zhuhai Vantone, i-Shanghai Puliter, i-Ningbo Jujia, i-Jiangmen Dezotye, njl. ngokwemfuno yezixhobo zombane kunye nezombane kunye namacandelo eemoto.
I-Polyether ether ketone (PEEK) yi-semi-crystalline, imathiriyeli ye-thermoplastic enevumba elimnandi. Okwangoku, kukho iintlobo ezintathu ze-polyether ether ketones kwimarike: i-resin ecocekileyo, i-glass fiber modified, i-carbon fiber modified. Okwangoku, i-Wiggs lelona lizwe livelisa i-polyether ketone, enamandla okuvelisa malunga neetoni ezingama-7000 ngonyaka, ethatha malunga ne-60% yomthamo wehlabathi uphelele. Uphuhliso lwetekhnoloji ye-POLYEther ether ketone e-China yaqala emva kwexesha, kwaye umthamo wemveliso ugxile kakhulu eZhongyan, Zhejiang Pengfu Long kunye neJida Te Plastics, ethatha i-80% yomthamo wemveliso eChina. Kulindeleke ukuba kwiminyaka emihlanu ezayo, imfuno ye-PEEK e-China iya kugcina izinga lokukhula kwe-15% ~ 20% kwaye lifikelele kwiitoni ze-3000 kwi-2025.
I-Polyimide (PI) yikhompawundi enuka kamnandi ye-heterocyclic polymer equlethe iringi ye-imide kwikhonkco eliphambili. Amashumi asixhenxe ekhulwini emveliso yehlabathi jikelele yePI iseUnited States, Japan, South Korea nakwamanye amazwe. Ifilimu ye-PI yaziwa nangokuthi "ifilimu yegolide" ngokusebenza kwayo kakuhle. Okwangoku, kukho malunga nama-70 abenzi befilimu ye-polyimide e-China, kunye nomthamo wokuvelisa malunga neetoni ezili-100. Zisetyenziswa kakhulu kwiimarike eziphantsi, ngelixa uphando oluzimeleyo kunye nenqanaba lophuhliso lweemveliso eziphezulu aluphezulu, kwaye zithunyelwa kakhulu kumazwe angaphandle.
I-PPS yenye yezona ntlobo zibalulekileyo nezixhaphakileyo ze-polyaryl sulfide resins. I-PPS inokusebenza kakuhle kwe-thermal, ukusebenza kombane, ukuxhathisa imichiza, ukuxhathisa kwi-radiation, i-flame retardant kunye nezinye iimpawu. I-PPS yiplastiki ekhethekileyo yobunjineli ye-thermoplastic enomsebenzi ogqwesileyo ogqibeleleyo kunye nokusebenza kweendleko eziphezulu. I-PPS isoloko isetyenziswa njengemathiriyeli yolwakhiwo lwepolymer. Isetyenziswa kakhulu kwimoto, i-elektroniki kunye nombane, iikhemikhali, oomatshini, i-aerospace, ishishini lenyukliya, ukutya kunye neshishini leziyobisi kunye namanye amacandelo.
Ukusuka kwintsimi yesicelo, iiplastiki ezikhethekileyo zobunjineli ngaphezu kwesicelo kwi-electronic, i-automotive, i-aerospace, izixhobo ezichanekileyo, kunye nezinye iindawo zendabuko, kunye ne-5 g yonxibelelwano, izithuthi zamandla amatsha, isixhumi soxinzelelo oluphezulu, i-electronics yabathengi, i-semiconductor, ukunakekelwa kwezempilo, amandla. kunye namanye amashishini, kunye nophuhliso olukhawulezayo lokusetyenziswa kweeplastiki ezizodwa zobunjineli nazo ziyanda, inani kunye nohlobo lwesicelo luyanda.
Ukususela ekuguqulweni komlambo ophakathi kunye nokucubungula, iiplastiki ezikhethekileyo zobunjineli zihlala zifuna ukuguqulwa ngeglasi / i-carbon fiber reinforcement, i-toughening, i-mineral filling, i-antistatic, i-lubrication, i-dyeing, i-wear resistance, i-alloy yokudibanisa, njl., ukuqhubela phambili ukunyusa ixabiso lesicelo sabo. . Iindlela zayo zokucwangcisa kunye ne-post-processing zibandakanya ukuguqulwa kokudibanisa, ukubunjwa kwe-injection, ifilimu ye-extrusion, i-impregnation composite, iiprofayili zebha, ukucutshungulwa komatshini, okuya kusebenzisa iintlobo zezongezo, izixhobo zokusebenza, njl.
