Txoj haujlwm "lub zog tshiab" muaj peb pawg, suav nrog ntau qhov kub thiab txias, lub zog tshwj xeeb, lub roj teeb muaj kev nyab xeeb siab, hluav taws xob tsav tsheb, thiab kev tsav tsheb ntse.
Raws li daim ntawv thov kev qhia, muaj ntau yam haujlwm uas muaj cov ntaub ntawv tshiab, lub zog tshiab thiab lwm yam haujlwm muaj feem xyuam. Cov ntaub ntawv tshiab koom nrog feem ntau suav nrog cov khoom siv polymer ua haujlwm siab thiab cov ntaub ntawv sib xyaw suav nrog UHMWPE, carbon fiber, aramid, thiab lwm yam, uas yuav coj tau ntau lub sijhawm rau cov tuam txhab kev lag luam.
Ultra-siab molecular hnyav polyethylene (UHMWPE)
Ultra-high molecular hnyav polyethylene (UHMWPE) muaj ntau yam zoo heev, xws li hnav tsis kam, cuam tshuam tsis kam, nws tus kheej lubrication, tshuaj corrosion kuj thiab kub tsis kam. Nws yog hu ua "magic yas". Nws cov saw hlau muaj xws li catalytic polymerization ntawm ethylene raw cov ntaub ntawv los ua UHMWPE hmoov, thiab tom qab ntawd los ntawm cov txheej txheem qhuav lossis ntub dej los ua UHMWPE fiber ntau.
Raws li cov tuam txhab tsim khoom lag luam tau ua tiav cov thev naus laus zis thev naus laus zis thiab paub txog UHMWPE cov thev naus laus zis ntau lawm, lub peev xwm ntau lawm ntawm ultra-siab molecular hnyav polyethylene tau nthuav dav sai. Raws li lub Peb Hlis 2024, cov khoom siv hauv tsev ultra-siab molecular hnyav polyethylene muaj peev xwm ntau tshaj 200, 000 tons / xyoo, lub peev xwm hauv kev tsim kho yog 310,000 tons, thiab muaj txog 370,{{8 }} tons / xyoo ntawm kev npaj tshiab muaj peev xwm.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, UHMWPE fiber ntau muaj cov yam ntxwv ntawm kev hnav tsis kam, siab cuam tshuam tsis kam, tshwj xeeb yooj, thiab lwm yam, thiab yog siv dav hauv kev tsim cov kaus mom hlau, cov hlua ua haujlwm siab, cov hnab looj tes tiv thaiv thiab lwm yam. Tsis tas li ntawd, UHMWPE kuj tau siv dav hauv lithium roj teeb diaphragms, daim hlau, cov kav dej thiab lwm yam. Nrog rau txoj kev loj hlob sai ntawm lub zog tshiab tsheb, qhov kev thov rau UHMWPE hauv thaj tsam ntawm lithium roj teeb diaphragms yuav nce ntxiv.
Carbon fiber ntau
Carbon fiber muaj cov yam ntxwv zoo xws li lub teeb yuag, lub zog siab, lub zog tsis zoo, cov hluav taws xob tsis txaus, thiab cov hluav taws xob loj heev, thiab cov thermal loj conductivity.
Lub hauv paus ntawm cov pa roj carbon fiber ntau hauv kev lag luam saw yog cov khoom siv tshuaj raw khoom, suav nrog acrylonitrile tau tom qab cov txheej txheem xws li refining thiab ammonia ntawm raw cov ntaub ntawv xws li roj av, thee, thiab natural gas.
Cov dej ntws hauv qab yog daim ntawv thov ntawm cov khoom siv carbon fiber ntau, suav nrog aerospace, cov khoom siv hauv tsev, cov khoom siv tsheb, cov khoom siv hluav taws xob tshiab, cov khoom siv ua kis las thiab lwm yam kev lag luam, nrog rau cov cua turbine hniav, aerospace, kev ua si thiab kev lom zem, thiab kev lag luam automotive account rau tag nrho. txog li 70%.
Aramid
Aramid yog cov khoom siv hluav taws xob ua haujlwm siab nrog lub zog siab, siab modulus, kub tsis kam, tshuaj tiv thaiv corrosion thiab lwm yam ntxwv. Nws yog dav siv hauv roj hmab, hluav taws xob, kev tiv thaiv, aerospace thiab lwm yam kev lag luam.
Lub sab sauv ntawm aramid kev lag luam saw feem ntau suav nrog cov khoom siv raw thiab cov khoom siv rau kev tsim cov aramid fibers, xws li m-phenylenediamine, isophthaloyl chloride, thiab lwm yam.
Qhov qis qis yog daim ntawv thov ntawm aramid fibers, suav nrog kev tiv thaiv kev nyab xeeb, aerospace, kev tiv thaiv ib puag ncig, khoom siv hluav taws xob thiab hluav taws xob thiab lwm yam haujlwm.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov aramid, qhov nkag teb chaws yog ua dav thiab dav. Piv txwv li, Minshida tsim cov ntawv aramid; Taihe Cov Khoom Siv Tshiab siv aramid hauv thaj tsam ntawm roj teeb cais txheej. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv ntau qhov chaw pej xeem xws li nres nres thiab cov log tsheb roj hmab.
