I-Plastics Ekhethekile Yobunjiniyela ibhekisela kumapulasitiki wobunjiniyela anezindawo eziphakeme kakhulu kanye nokushisa kwensiza yesikhathi eside ngenhla kwe-150 ℃. Ngokuvamile ukumelana nokushisa okuphezulu okuphezulu, ukumelana nemisebe, ukumelana kwe-hydrolysis, ukumelana nesimo sezulu, ukumelana nokugqwala, izinga lokuvuselelwa kwemvelo, ukumelana nokukhathala kanye nezinye izinzuzo. Kunezinhlobo eziningi ze-plastitics ekhethekile yobunjiniyela, kufaka phakathi i-polyliquid Crystal Polymer (LCP), i-polythert ether ketone (POLYIMIDE (PPS), i-Phenyl Sulfide (PSF), i-Polyaromatic Ester (PTFE, I-PVDF, i-PCTFE, PFA), njll.
Ngokombono womlando kanye nesimo samanje, amazwe aseYurophu nawaseMelika kusuka ekudleni kwe-polyomide ngeminyaka yo-1960 kanye nokufika kwe-polythert ether Ketone ekuqaleni kweminyaka yama-1980s, kuze kube manje kwakha izinhlobo ezingaphezu kuka-10 zobunjiniyela be-plastitics ekhethekile. Ipulasitiki ekhethekile yaseChina yaqala maphakathi ne-1990s. Njengamanje, imboni isesigabeni sokuqala sentuthuko, kepha ijubane lokuthuthuka liyashesha. Amapulasitiki wobunjiniyela obuningana ajwayelekile athathwa njengezibonelo.
I-Liquid Crystal Polymer (LCP) uhlobo lwe-polyester lwe-polyester oluqukethe inani elikhulu lesakhiwo se-benzene ring eqinile ku-main chain, futhi izoshintsha ibe yindawo enhle yokushisa, futhi inezakhiwo ezinhle kakhulu. Njengamanje, umthamo womhlaba wonke we-Liquid Crystal Polymer ucishe abe ngamathani / ngonyaka wamathani angama-80,000, kanye ne-United States kanye ne-akhawunti yaseJapan cishe ama-80% omthamo ophelele emhlabeni jikelele. Umkhakha we-LCP waseChina uqale sekwephuzile, ngekhono lamanje lokukhiqiza eliphelele lamathani / unyaka. Abakhiqizi abaphambili bafaka phakathi izinto ezintsha zeShenzhen Amanzi, Zhuhai Vantone, eShanghai puliter, i-Ningbo juzi, njll. Kulindeleke ukuthi ukusetshenziswa okuphelele kwe-LCP kuzogcina izinga lokukhula kwamathani angaphezu kuka-625, kuqhutshwa amathani angama-40,000 ngokufunwa kwezinto zikagesi kanye nezenzeli kanye nemikhakha yezimoto.
I-Polythert Ether Ketone (Peek) iyi-semi-crystalline, i-thermoplastic aromatic polymer impahla. Njengamanje, kunezinhlobo ezintathu ze-polytheth ether ketones emakethe: i-resin emsulwa, i-fiber fiber eguquliwe, i-carbon fiber eguquliwe. Njengamanje, amaWiggs akhiqiza umhlaba omkhulu kakhulu emhlabeni we-polythert Ketone, onamandla okukhiqiza amathani / unyaka ongamathani acishe abe ngu-7000, abizwe cishe ama-60% omhlaba wonke emhlabeni. Ukuthuthukiswa kwezobuchwepheshe kwe-polythear ether ketone eChina kwaqala sekwephuzile, futhi umthamo wokukhiqiza ugxile kakhulu eZhongyan, zhejiang pengfu ubude ne-jida te plastics, accounting for amakhono okukhiqiza aphelele eChina. Kulindelwe ukuthi eminyakeni emihlanu ezayo, isidingo se-Peek eChina sizogcina izinga lokukhula le-15% ~ 20% futhi lifinyelele kumathani angama-3000 ngo-2025.
I-Polyimide (PI) iyi-heterocyclic polymer compler compler equkethe indandatho ye-limide ku-main chain. Amaphesenti angamashumi ayisikhombisa okukhiqizwa komhlaba we-PI e-United States, eJapan, eSouth Korea nakwamanye amazwe. Ifilimu le-PI yaziwa nangokuthi "ifilimu legolide" ukusebenza kwayo okuhle. Njengamanje, kunabakhiqizi befilimu abangama-70 eChina, kanti umthamo wokukhiqiza ongamathani ayi-100. Zisetshenziswa ikakhulukazi emakethe ephansi, kanti izinga lokucwaninga elizimele kanye nentuthuko yemikhiqizo ephezulu aliphakeme, futhi angeniswa kakhulu.
I-PPS ingenye yezinhlobo ezibaluleke kakhulu nezijwayelekile zama-polyaryl sulfide resins. I-PPS inokusebenza okuhle kakhulu okushisayo, ukusebenza kukagesi, ukumelana kwamakhemikhali, ukumelana nemisebe, i-flame retardant nezinye izakhiwo. I-PPS iyipulasitiki ekhethekile ye-thermoplastic ekhethekile enokusebenza okuhle kakhulu okuphelele nokusebenza kwezindleko eziphakeme. I-PPS ivame ukusetshenziswa njengezinto ezihlelekile ze-polymer. Kusetshenziswa kabanzi e-aromobile, ngogesi kanye nogesi, amakhemikhali, amakhemikhali, i-aerospace, imboni yenuzi, imboni yokudla kanye nezidakamizwa nezinye izinkambu.
Ukusuka kwinkambu yesicelo, amapulasitiki wobunjiniyela akhethekile ngaphezu kwesicelo ku-elekthronikhi, ezithunzini, izimoto zendabuko, izimoto ezintsha ze-Energy, i-semiconductor, i-semiconductor, ukunakekelwa kwengqondo, amandla Futhi ezinye izimboni, ngokuthuthukiswa okusheshayo kokusetshenziswa kwe-plastiting ekhethekile yobunjiniyela nakho kuyanda, inani nohlobo lohlelo lokusebenza lukhuphuka.
Kusuka ekuguqukeni okuphakathi nendawo kanye nokusebenza, amapulasitiki wobunjiniyela akhethekile adinga ukuguqulwa yi-glass / carbon fiber ukuqiniswa, ukugcwaliswa kwamaminerali, ukugcotshwa kwamaminerali, i-antistatic, i-anc, ukuhlanganisa i-alloy, ukuthuthukisa ukuthuthukisa inani labo lesicelo . Izindlela zayo zokucubungula kanye nokusebenza kwangemva kokucutshungulwa zifaka ukuguqulwa okuhlanganisiwe, ukuhlanganiswa kwe-imjolomu, amafilimu okufakwayo, amaphrofayili we-bar, ukucubungula imishini, okuzosebenzisa imishini ehlukahlukene, njll.
