Tshwj xeeb engineering plastics xa mus rau engineering plastics nrog cov khoom siv dav dav thiab kev pabcuam ntev kub siab tshaj 150 ℃.Feem ntau ob qho tib si kub tsis kam, hluav taws xob tsis kam, hydrolysis tsis kam, huab cua tsis kam, corrosion kuj, ntuj nplaim retardant, tsis tshua muaj thermal expansion tus nqi, qaug zog thiab lwm yam zoo.Muaj ntau yam tshwj xeeb engineering yas, suav nrog polyliquid crystal polymer (LCP), polyether ether ketone (PEEK), polyimide (PI), phenyl sulfide (PPS), polysulfone (PSF), polyaromatic ester (PAR), fluoropolymer (PTFE, PVDF, PCTFE, PFA), thiab lwm yam.
Los ntawm qhov kev xav ntawm keeb kwm thiab cov xwm txheej tam sim no, cov teb chaws Europe thiab Asmeskas los ntawm qhov tshwm sim ntawm polyimide nyob rau hauv 1960s thiab lub advent ntawm polyether ether ketone nyob rau hauv thaum ntxov 1980s, mus txog rau tam sim no tau tsim ntau tshaj 10 yam tshwj xeeb engineering plastics industrialization.Tuam Tshoj tus tshwj xeeb engineering plastics pib nyob rau hauv nruab nrab thiab lig 1990s.Tam sim no, kev lag luam yog nyob rau hauv thawj theem ntawm txoj kev loj hlob, tab sis txoj kev loj hlob sai.Ntau qhov tshwj xeeb engineering plastics raug coj los ua piv txwv.
Cov kua siv lead ua kua polymer (LCP) yog ib yam ntawm cov khoom siv polyester uas muaj cov khoom siv loj ntawm benzene nplhaib qauv ntawm cov saw tseem ceeb, uas yuav hloov mus rau hauv cov kua siv lead ua kua hauv ib lub xeev cua sov, thiab muaj cov khoom zoo heev.Tam sim no, lub ntiaj teb muaj peev xwm ntawm cov kua siv lead ua kua polymer yog kwv yees li 80,000 tons / xyoo, thiab Tebchaws Meskas thiab Nyij Pooj suav txog li 80% ntawm lub peev xwm thoob ntiaj teb.Tuam Tshoj txoj kev lag luam LCP pib lig, nrog rau tam sim no tag nrho cov peev txheej tsim tau txog 20,000 tons / xyoo.Cov tuam txhab tseem ceeb suav nrog Shenzhen Dej Cov Khoom Siv Tshiab, Zhuhai Vantone, Shanghai Puliter, Ningbo Jujia, Jiangmen Dezotye, thiab lwm yam. Nws xav tias tag nrho cov kev siv ntawm LCP yuav tuav qhov kev loj hlob ntawm ntau tshaj 6% thiab tshaj 40,000 tons hauv 2025, tau tsav los ntawm qhov kev thov ntawm cov khoom siv hluav taws xob thiab hluav taws xob thiab tsheb sectors.
Polyether ether ketone (PEEK) yog semi-crystalline, thermoplastic aromatic polymer khoom.Tam sim no, muaj peb hom polyether ether ketones nyob rau hauv kev ua lag luam: ntshiab resin, iav fiber hloov, carbon fiber hloov.Tam sim no, Wiggs yog lub ntiaj teb loj tshaj plaws tsim khoom ntawm polyether ketone, muaj peev xwm ntau lawm txog 7000 tons / xyoo, suav txog li 60% ntawm lub ntiaj teb tag nrho lub peev xwm.Kev txhim kho thev naus laus zis ntawm POLYEther ether ketone hauv Suav teb tau pib lig, thiab cov peev txheej tsim tau tsuas yog nyob hauv Zhongyan, Zhejiang Pengfu Long thiab Jida Te Plastics, suav txog 80% ntawm tag nrho cov peev txheej hauv Suav teb.Nws cia siab tias nyob rau hauv tsib xyoos tom ntej no, qhov kev thov rau PEEK hauv Suav teb yuav tuav qhov kev loj hlob ntawm 15% ~ 20% thiab ncav cuag 3000 tons hauv 2025.
Polyimide (PI) yog ib qho tshuaj tsw qab heterocyclic polymer compound uas muaj lub nplhaib imide hauv cov saw tseem ceeb.Xya caum feem pua ntawm PI kev tsim khoom thoob ntiaj teb yog nyob hauv Tebchaws Meskas, Nyiv, Kaus Lim Qab Teb thiab lwm lub tebchaws.PI zaj duab xis tseem hu ua "kub zaj duab xis" rau nws cov kev ua tau zoo heev.Tam sim no, muaj txog 70 polyimide zaj duab xis manufacturers nyob rau hauv Suav teb, muaj peev xwm ntau lawm txog 100 tons.Lawv tsuas yog siv nyob rau hauv kev ua lag luam qis kawg nkaus, thaum qhov kev tshawb fawb ywj pheej thiab kev txhim kho qib ntawm cov khoom siv high-end tsis siab, thiab lawv feem ntau yog imported.
PPS yog ib qho tseem ceeb tshaj plaws thiab ntau hom polyaryl sulfide resins.PPS muaj kev ua haujlwm zoo thermal, kev ua haujlwm hluav taws xob, tshuaj tiv thaiv, hluav taws xob tiv thaiv, nplaim hluav taws thiab lwm yam khoom.PPS yog cov thermoplastic tshwj xeeb engineering yas nrog kev ua tau zoo thiab kev ua haujlwm siab.PPS feem ntau yog siv los ua cov khoom siv polymer.Nws yog dav siv nyob rau hauv tsheb, hluav taws xob thiab hluav taws xob, tshuaj, machinery, aerospace, nuclear kev lag luam, zaub mov thiab tshuaj kev lag luam thiab lwm yam kev lag luam.
Los ntawm daim ntawv thov teb, tshwj xeeb engineering yas ntxiv rau daim ntawv thov hauv hluav taws xob, tsheb, aerospace, precision instruments, thiab lwm yam kev sib txuas lus, nrog 5 g kev sib txuas lus, lub zog tshiab tsheb, kev sib txuas siab, cov khoom siv hluav taws xob, semiconductor, kev noj qab haus huv, lub zog. thiab lwm yam kev lag luam, nrog rau kev loj hlob sai ntawm daim ntawv thov tshwj xeeb engineering plastics tseem nthuav, tus nqi thiab hom ntawv thov yog nce.
Los ntawm kev hloov kho thiab kev ua haujlwm nruab nrab, cov yas tshwj xeeb engineering feem ntau yuav tsum tau hloov kho los ntawm iav / carbon fiber reinforcement, toughening, ntxhia sau, antistatic, lubrication, dyeing, hnav tsis kam, sib xyaw alloy, thiab lwm yam, txhawm rau txhim kho lawv daim ntawv thov nqi. .Nws cov txheej txheem ua thiab tom qab ua tiav suav nrog kev hloov kho, kev txhaj tshuaj molding, extrusion zaj duab xis, impregnation composite, bar profiles, mechanical processing, uas yuav siv ntau yam additives, ua khoom, thiab lwm yam.
