Dab tsi yog LFT composites?
Ntev Fiber Composite yog dab tsi
Ntev fibers composites xa mus rau ib hom khoom sib xyaw uas yog tsim los ntawm cov fibers ntev embedded hauv cov khoom siv matrix. Cov fibers no tuaj yeem tsim los ntawm ntau yam khoom xws li iav, carbon, lossis aramid thiab tuaj yeem ntev li ob peb nti. Cov khoom siv matrix, ntawm qhov tod tes, feem ntau yog polymer.
Cov fibers ntev nyob rau hauv cov khoom siv sib xyaw no muab ntau yam khoom siv, xws li lub zog siab thiab nruj, uas ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev ncaj ncees yog qhov tseem ceeb. Cov khoom no tau ua tiav vim tias cov fibers ntev muab txoj hauv kev txuas mus ntxiv rau kev xa cov rog hauv cov khoom sib xyaw, uas ua rau muaj txiaj ntsig zoo dua cov kabmob.
Cov txiaj ntsig ntawm LFT Long Fiber Composites
------
Ib qho txiaj ntsig tseem ceeb ntawm cov khoom siv fiber ntau ntev yog lawv lub peev xwm los hloov kho rau cov ntawv thov tshwj xeeb. Qhov no yog vim hais tias hom thiab ntev ntawm fibers siv, nrog rau kev xaiv ntawm cov khoom siv matrix, tuaj yeem raug txiav kom ua tiav cov khoom siv kho tshuab tshwj xeeb. Piv txwv li, yog tias yuav tsum muaj qhov sib piv ntawm lub zog-rau-hnyav, carbon fibers yuav siv tau. Xwb, yog tias muaj kev txhawj xeeb, aramid fibers yuav raug xaiv.
Cov fiber ntau ntev kuj muaj qhov ua haujlwm siab rau qaug zog thiab cuam tshuam, txhais tau hais tias lawv tsis tshua muaj kev poob qis hauv kev rov ua dua lossis cuam tshuam tam sim ntawd. Qhov no ua rau lawv zoo tagnrho rau kev siv hauv kev siv xws li aerospace, tsheb, thiab cov khoom ua si.
Muaj ntau txoj kev tsim khoom siv los ua cov fiber ntau ntev, nrog rau kev txhaj tshuaj molding thiab pultrusion. Hauv kev txhaj tshuaj molding, cov khoom sib xyaw yog txhaj rau hauv lub pwm kab noj hniav thiab tso cai rau kom khov rau hauv cov duab ntawm qhov xav tau. Pultrusion, ntawm qhov tod tes, yuav rub cov khoom sib xyaw los ntawm kev tuag los tsim qhov ntev ntawm cov khoom.

Kev Sib Tham Zoo Tshaj Plaws
Xyoo 2021, ib tus neeg siv khoom ua khoom siv hauv tsev tuaj cuag peb thiab hais tias, "Cov khoom siv PP-GF peb siv tam sim no muaj kev ua haujlwm tsis txaus, thiab peb xav tau cov khoom siv ua haujlwm siab los txhim kho lub zog thiab tawv khoom ua haujlwm ntawm cov tshuab ntxhua khaub ncaws."
Tom qab soj ntsuam cov lus pom zoo los ntawm peb lub tuam tsev technical, peb tau hais kom cov neeg siv khoom siv "LFT-G® PP-NG05-LGF50%sib tov PP raw resin los ua cov khoom sib xyaw. Tom qab peb cov kev taw qhia tsim nyog, cov khoom siv tshuab ntawm lub tshuab ntxhua khaub ncaws ua los ntawm pebLFT-G® PP-NG05-LGF50%cov khoom tau txhim kho los ntawm 30%-40%. Cov neeg siv khoom tawm tswv yim txaus siab heev nrog kev siv cov txiaj ntsig, rau cov neeg siv khoom hauv lub hom phiaj lub teb chaws ua lag luam kom tau txais txiaj ntsig zoo ntawm kev lag luam. Peb tau xa tawm ntau dua 2,000MT cov ntaub ntawv rau peb cov neeg siv khoom, thiab peb muaj peev xwm muab peb cov neeg siv khoom txuas ntxiv thiab ruaj khov.
