Amapulasitiki obunjiniyela akhethekile abhekisela kumapulasitiki obunjiniyela anezici eziphelele eziphelele kanye nezinga lokushisa lesevisi yesikhathi eside elingaphezu kuka-150 ℃. Ngokuvamile kokubili ukumelana nokushisa okuphezulu, ukumelana nemisebe, ukumelana ne-hydrolysis, ukumelana nesimo sezulu, ukumelana nokugqwala, ukubuyiswa kwamalangabi emvelo, izinga eliphansi lokwanda okushisayo, ukumelana nokukhathala nezinye izinzuzo. Kunezinhlobo eziningi zepulasitiki ekhethekile yobunjiniyela, okuhlanganisa 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), njll.
Ngokombono womlando kanye nesimo samanje, amazwe aseYurophu naseMelika kusukela ekufikeni kwe-polyimide ngawo-1960 kanye nokufika kwe-polyether ether ketone ekuqaleni kwawo-1980, kuze kube manje kuye kwakha izinhlobo ezingaphezu kwezingu-10 zezimboni ezikhethekile zepulasitiki zobunjiniyela. Amapulasitiki onjiniyela akhethekile aseShayina aqala maphakathi nawo-1990 ngasekupheleni kwawo. Njengamanje, imboni isesigabeni sokuqala sokuthuthukiswa, kodwa isivinini sokuthuthukiswa siyashesha. Amapulasitiki amaningana ajwayelekile obunjiniyela athathwa njengezibonelo.
I-Liquid crystal polymer (LCP) iwuhlobo lwe-polyester enephunga elimnandi equkethe inani elikhulu lesakhiwo seringi ye-benzene eqinile eketangoni elikhulu, elizoshintsha libe yikristalu eliwuketshezi ngaphansi kwesimo sokushisisa esithile, futhi linezici ezinhle kakhulu ezihlanganisayo. Njengamanje, umthamo womhlaba wonke we-liquid crystal polymer ungamathani angama-80,000 ngonyaka, kanti i-United States neJapan zenza cishe amaphesenti angama-80 yenani eliphelele lomhlaba. Imboni ye-LCP yaseChina iqale sekwephuzile, nenani lamanje lokukhiqiza elingamathani angama-20,000 ngonyaka. Abakhiqizi abakhulu bahlanganisa i-Shenzhen Water New Materials, i-Zhuhai Vantone, i-Shanghai Puliter, i-Ningbo Jujia, i-Jiangmen Dezotye, njll. Kulindeleke ukuthi ukusetshenziswa okuphelele kwe-LCP kuzogcina izinga lokukhula elingaphezu kuka-6% futhi kudlule amathani angu-40,000 ngo-2025, ngesidingo sezinto zikagesi nezikagesi kanye nemikhakha yezimoto.
I-Polyether ether ketone (PEEK) iyi-semi-crystalline, i-thermoplastic enuka kamnandi ye-polymer material. Njengamanje, kunezinhlobo ezintathu zamaketone e-polyether ether emakethe: i-resin ehlanzekile, i-glass fiber modified, i-carbon fiber modified. Njengamanje, i-Wiggs ingumkhiqizi omkhulu kunawo wonke emhlabeni we-polyether ketone, enamandla okukhiqiza angaba amathani ayi-7000/ngonyaka, ehlanganisa cishe u-60% wawo wonke amandla omhlaba. Ukuthuthukiswa kobuchwepheshe be-POLYEther ether ketone e-China kuqale sekwephuzile, futhi amandla okukhiqiza agxile kakhulu eZhongyan, Zhejiang Pengfu Long nase-Jida Te Plastics, okubalelwa ku-80% wesamba somthamo wokukhiqiza eChina. Kulindeleke ukuthi eminyakeni emihlanu ezayo, isidingo se-PEEK e-China sizogcina izinga lokukhula lika-15% ~ 20% futhi sifinyelele amathani angu-3000 ngo-2025.
I-Polyimide (PI) iyinhlanganisela ye-heterocyclic polymer enephunga elimnandi equkethe iringi ye-imide ochungechungeni oluyinhloko. Amaphesenti angamashumi ayisikhombisa okukhiqizwa kwe-PI emhlabeni wonke ase-United States, Japan, South Korea nakwamanye amazwe. Ifilimu ye-PI yaziwa nangokuthi "ifilimu yegolide" ngokusebenza kwayo okuhle kakhulu. Njengamanje, kunabakhiqizi bamafilimu be-polyimide abangaba ngu-70 e-China, abanekhono lokukhiqiza elingamathani ayi-100. Zisetshenziswa kakhulu emakethe esezingeni eliphansi, kuyilapho izinga lokucwaninga elizimele kanye nentuthuko yemikhiqizo ephezulu ayiphezulu, futhi ithengwa kakhulu kwamanye amazwe.
I-PPS ingenye yezinhlobo ezibaluleke kakhulu nezivamile zama-polyaryl sulfide resins. I-PPS inokusebenza okuhle kakhulu kokushisa, ukusebenza kukagesi, ukumelana namakhemikhali, ukumelana nemisebe, i-flame retardant nezinye izakhiwo. I-PPS iyipulasitiki yobunjiniyela ekhethekile ye-thermoplastic enokusebenza okuhle kakhulu okuphelele nokusebenza kwezindleko eziphezulu. I-PPS ivame ukusetshenziswa njengesakhiwo se-polymer material. Isetshenziswa kabanzi embonini yezimoto, kagesi kanye nekagesi, amakhemikhali, imishini, i-aerospace, imboni yenuzi, embonini yokudla nezidakamizwa neminye imikhakha.
Kusukela emkhakheni wokufaka isicelo, amapulasitiki obunjiniyela akhethekile ngaphezu kokusetshenziswa ku-elekthronikhi, izimoto, i-aerospace, izinsimbi ezinembayo, nezinye izindawo zendabuko, ezinokuxhumana okungu-5 g, izimoto zamandla amasha, isixhumi esinengcindezi ephezulu, izinto zikagesi zabathengi, isemiconductor, ukunakekelwa kwezempilo, amandla. kanye nezinye izimboni, ngokuthuthuka okusheshayo kokusetshenziswa kwepulasitiki ekhethekile yobunjiniyela nakho kuyanda, inani kanye nohlobo lohlelo luyanda.
Kusukela ekulungiseni nasekucutshungulweni kokusakaza okumaphakathi, amapulasitiki akhethekile obunjiniyela ngokuvamile adinga ukuguqulwa ngengilazi/i-carbon fiber reinforcement, ukuqina, ukugcwaliswa kwamaminerali, i-antistatic, i-lubrication, ukudaya, ukumelana nokugqokwa, ingxubevange yokuhlanganisa, njll., ukuze kuthuthukiswe inani lesicelo sawo. . Ukucubungula kwayo kanye nezindlela zokucubungula emva kokucubungula zihlanganisa ukuguqulwa kokuxuba, ukubunjwa komjovo, ifilimu ye-extrusion, i-impregnation composite, amaphrofayili ebha, ukucubungula ngomshini, okuzosebenzisa izithasiselo ezihlukahlukene, imishini yokucubungula, njll.
