Kev Txav Mus Los Uas Muaj Cov Pa roj Carbon Tsawg: Basalt Fiber Hloov Cov Khoom Siv Sab Hauv Tsheb

Ua lub hauv paus tseem ceeb ntawm kev tsav tsheb thiab caij tsheb, kev txhim kho cov khoom siv hauv chav tsheb tau dhau los ua qhov tseem ceeb rau kev hloov pauv mus rau kev mus ncig uas tsis muaj carbon ntau. Tam sim no, cov khoom siv hauv chav tsheb ntsib cov teeb meem xws li tsis txaus rau ib puag ncig, hnyav dhau, thiab muaj kev phom sij rau kev noj qab haus huv. Cov yas ib txwm muaj, tawv, thiab cov khoom xa tuaj los ntawm txawv teb chaws Cov Khoom Siv Sib Xyaws tsis yog tsuas yog siv hluav taws xob ntau xwb tab sis kuj raug kev txom nyem los ntawm VOC emissions thiab nyuaj rau kev siv dua tshiab, uas tsis sib haum nrog lub tswv yim ntawm kev mus ncig uas tsis muaj carbon ntau.Cov fiber basalt, ua ib qho fiber inorganic ntsuab ntuj, yog ua los ntawm cov basalt ntuj los ntawm kev kos duab yaj. Nws muaj cov txiaj ntsig tshwj xeeb xws li cov pa roj carbon tsawg, kev phooj ywg ib puag ncig, Sib dua, tiv taus huab cua zoo heev, thiab cov khoom siv kho tshuab zoo heev. Tom qab kev hloov kho sib xyaw thiab kev tsim kho tshiab, nws tau ua tiav daim ntawv thov loj hauv kev siv cov khoom siv hauv tsheb, rov kho dua cov khoom siv hauv tsheb los ntawm ntau qhov ntawm kev tiv thaiv ib puag ncig, kev ua tau zoo, thiab tus nqi, txhaj tshuaj lub zog tseem ceeb rau hauv kev mus ncig uas tsis muaj pa roj carbon ntau.

Cov yam ntxwv tseem ceeb ntawm basalt fiber Ua kom haum rau qhov xav tau kev tsim kho tshiab uas tsis muaj carbon ntau ntawm cov khoom siv hauv tsheb, tsim kom muaj kev sib tw tseem ceeb. Hais txog kev tiv thaiv ib puag ncig thiab kev tiv thaiv ib puag ncig, kev tsim cov fiber basalt tsis tas yuav hloov kho tshuaj lom neeg, tsuas yog cia siab rau kev yaj thiab kos duab xwb. Kev siv hluav taws xob tsawg dua 20% -30% piv rau cov iav fiber thiab tsawg dua 60% piv rau cov carbon fiber, tsis muaj cov pa phem. Cov khoom sib xyaw ua ke basalt fiber pov tseg tuaj yeem lwj lossis zom thiab rov ua dua tshiab, khaws cia ntau dua 80% ntawm lawv cov kev ua tau zoo. Tag nrho cov pa roj carbon hauv lub neej yog qis dua 45% -60% piv rau cov khoom siv hauv tsheb ib txwm muaj, ua raws li lub hom phiaj tseem ceeb ntawm "kev txo cov pa roj carbon thiab txo cov pa phem" hauv kev mus ncig uas tsis muaj carbon ntau. Hais txog kev sib dua, cov fiber basalt muaj qhov ceev tsuas yog 2.6-2.8 g / cm³, sib piv rau cov iav fiber thiab tsawg dua 60% sib dua li hlau. Cov khoom sib xyaw ua los ntawm nws muaj lub zog tshwj xeeb 3-4 npaug ntawm cov yas ib txwm muaj thiab 2-3 npaug ntawm cov txhuas alloys. Siv nws los tsim cov khoom siv hauv chav tsev tuaj yeem ua tiav qhov hnyav txo tau 30% -50%, txo qis kev siv zog ntawm lub tsheb thiab pab txhawb kom muaj kev nce qib ntawm cov tsheb fais fab tshiab.

Hais txog kev noj qab haus huv thiab kev ua tau zoo, cov ntaub ntawv basalt fiber composite tsis muaj ntxhiab thiab muaj cov pa phem VOC tsawg. Kev tso tawm cov pa phem xws li formaldehyde thiab benzene qis dua cov qauv ib puag ncig hauv tebchaws rau cov tsheb cabins, daws cov teeb meem kev noj qab haus huv ntawm cov ntaub ntawv ib txwm muaj. Lawv kuj muaj kev tiv thaiv huab cua zoo heev, kev tiv thaiv hnav, thiab kev tiv thaiv hluav taws. Tom qab kev kub siab thiab qis (-40 ℃ txog + 80 ℃) thiab kev kuaj UV laus, qhov kev ua tau zoo khaws cia ncav cuag ntau dua 85%. Kev tiv thaiv hnav yog plaub npaug zoo dua li cov yas ib txwm muaj, thiab qhov ntsuas hluav taws kub ncav cuag UL94 V-0, ua rau lawv haum rau qhov chaw nyuaj ntawm cov tsheb cabins thiab ua kom muaj kev nyab xeeb tsav tsheb.

Los ntawm kev hloov kho thiab kev ua kom zoo dua ntawm cov txheej txheem, cov fiber basalt ua rau muaj kev hloov kho dua tshiab ntawm cov khoom siv hauv ntau yam khoom siv hauv lub tsheb. Hauv lub kaw lus zaum, cov khoom siv PP/PA uas muaj fiber basalt fiber ntxiv rau siv los tsim lub rooj zaum, nraub qaum, thiab lub taub hau, txo qhov hnyav ntau dua 50% piv rau cov thav duab hlau ib txwm muaj thiab txhim kho kev phooj ywg ib puag ncig los ntawm 30% piv rau cov thav duab iav fiber sib xyaw. Ua ke nrog cov ntaub rooj zaum ua los ntawm cov ntaub basalt fiber sib xyaw tsis yog ntaub, cov ntaub no muaj kev ua pa tau zoo, cov khoom tua kab mob, thiab kev tiv thaiv hluav taws, txo cov pa phem VOC ntau dua 70%, yog li txhim kho kev tsav tsheb xis nyob thiab kev noj qab haus huv. Tom qab siv lub kaw lus zaum no, ib lub tuam txhab tsim tsheb hauv tsev tau pom tias qhov hnyav ntawm lub tsheb thauj neeg caij tsheb poob qis li 6-8 kg, thiab nce 6% -8% ntawm qhov ntau thiab tsawg ntawm cov tsheb fais fab tshiab.

Nyob rau hauv thaj chaw ntawm sab hauv vaj huam sib luag, dashboards, center consoles, thiab qhov rooj vaj huam sib luag ua los ntawm basalt fiber thiab cov khoom sib xyaw ua los ntawm cov khoom siv bio-based resin tuaj yeem ua raws li cov qauv ntawm cov ntoo, hlau, thiab carbon fiber, ua rau muaj kev tsim qauv raws li tus kheej. Cov khoom siv no muaj qhov nyuaj ntawm HRC 30 lossis siab dua, ua rau nws tsis yooj yim khawb, yooj yim ntxuav, thiab muaj lub neej ntev dua ob npaug ntawm cov yas ib txwm muaj. Tib lub sijhawm, nws cov khoom sib dua txo qhov hnyav tag nrho ntawm lub tsheb thauj neeg, thiab ua ke nrog cov txheej txheem molding, txo cov lej ntawm cov pob qij txha, txhim kho qhov kev ua tiav ntawm lub tsheb thauj neeg. Ntxiv mus, cov khoom sib xyaw no kuj tseem siv tau rau hauv cov khoom xws li cov thawv cia khoom ntawm lub tsheb thauj neeg thiab cov chaw so tes, nthuav dav ntxiv rau kev siv cov khoom siv carbon tsawg.

Nyob rau hauv cov nqe lus ntawm cov khoom ua haujlwm, Cov khoom siv sib xyaw ua ke basalt fiber reinforced siv rau hauv cov khoom tseem ceeb xws li cov kav dej tiv thaiv hluav taws xob hauv chav neeg caij tsheb, cov kav dej cua txias, thiab cov thav duab ntawm lub kauj tsheb. Cov kav dej tiv thaiv hluav taws xob, nrog nws cov rwb thaiv tsev zoo dua thiab tiv taus kev hnav, tuaj yeem hloov cov kav dej PVC ib txwm muaj, txo qhov hnyav los ntawm 40% thiab ntev lub neej kev pabcuam los ntawm 3 zaug. Cov kav dej cua txias siv cov khoom siv ua npuas ncauj basalt fiber composite nrog cov thermal conductivity qis li 0.03 W / (m · K), txhim kho kev rwb thaiv tsev los ntawm 50%, txo cov cua txias siv hluav taws xob, thiab tib lub sijhawm muaj kev ua tau zoo heev txo suab nrov, txo cov suab nrov hauv chav tsev los ntawm 10-15 dB thiab txhim kho kev caij ntsiag to.

Kev tsim kho tshiab hauv tsev thiab kev txhim kho kev lag luam txuas ntxiv ua rau muaj kev hloov pauv ntawm cov fiber basalt rau cov ntaub ntawv hauv tsev. Cov tuam txhab hauv tsev txhim kho lub zog sib txuas ntawm cov fiber thiab cov resin matrix los ntawm kev hloov kho qhov chaw ntawm cov fiber (silane coupling agents, plasma treatment), ua rau cov khoom siv kho tshuab ntawm cov khoom sib xyaw ua ke nce 25% -35%. Lawv kuj tau tsim cov txheej txheem molding xws li kev txhaj tshuaj molding, compression molding, thiab vacuum adsorption hloov kho rau cov khoom hauv tsev, ua rau muaj kev tsim khoom ntau ntawm cov khoom sib xyaw ua ke, ua rau lub voj voog molding luv dua 30% piv rau cov txheej txheem ib txwm muaj, thiab txo cov nqi los ntawm 20% -30%. Ntxiv mus, kev koom tes ntawm kev lag luam-kev kawm-kev tshawb fawb tab tom tsim ib lub kaw lus kev lag luam tiav uas suav nrog "cov ntaub ntawv raw-cov ntaub ntawv sib xyaw-molding-recycling," tsim cov pawg lag luam hauv cov cheeb tsam nplua nuj basalt xws li Sichuan thiab Hebei xeev. Qhov no ua rau muaj kev muab cov ntaub ntawv hauv tsev, txo cov nqi khoom siv thiab cov pa roj carbon dioxide.

Yav tom ntej, nrog rau kev ua dua tshiab tas mus li ntawm basalt fiber sib xyaw ua ke thev naus laus zis, nws yuav tsim mus rau "kev koom ua ke ua haujlwm, kev hloov kho tus kheej, thiab tus nqi qis." Los ntawm kev sib xyaw ua ke nrog cov sensors ntse thiab cov ntaub ntawv luminescent, cov khoom siv ua haujlwm ntse hauv lub tsheb (xws li cov vaj huam sib luag sab hauv luminescent thiab cov rooj zaum siab-sensitive) tuaj yeem tsim tau. Ua ke nrog 3D luam ntawv thev naus laus zis, cov ntaub ntawv hauv lub tsheb tus kheej tuaj yeem hloov kho kom haum rau cov qauv xav tau ntawm cov qauv tsheb sib txawv. Raws li cov ntawv thov loj loj nce qib, cov nqi yuav txo qis ntxiv, txhawb nqa nws txoj kev siv dav hauv cov tsheb nruab nrab mus rau qis kawg. Nrog cov pa roj carbon tsawg ua nws lub hauv paus thiab kev ua tau zoo ua nws txoj kev txhawb nqa, basalt fiber tab tom hloov kho lub ecosystem tshiab ntawm cov ntaub ntawv hauv lub tsheb, muab kev txhawb nqa cov khoom siv tseem ceeb rau kev mus ncig qis-carbon, thiab pab txhawb rau kev txhim kho ntsuab thiab zoo ntawm kev lag luam tsheb.
