Cov thev naus laus zis niaj hnub niaj hnub niaj hnub qhia ntau yam tshiab rau hauv peb lub neej uas tuaj yeem ua rau nws yooj yim heev lossis txhim kho nws qhov zoo. Tshwj xeeb, qhov no cuam tshuam txog kev tsim cov kev tsim kho tshiab hauv kev lag luam chemical, cov khoom siv uas yuav luag txhua ceg ntawm tib neeg kev ua haujlwm. Ib qho kev paub tam sim no yog cov khoom siv carbon. Peb yuav tham txog nws kom ntxaws ntau li ntau tau hauv kab lus.

Definition

Carbon yog qhov tseeb ntawm carbon fiber, uas yog, cov khoom sib xyaw nrog cov txheej txheem sib txawv. Cias muab, carbon fibers nyob rau hauv daim ntawv ntawm lub web, lub plhaub ntawm uas, nyob rau hauv lem, yog ua los ntawm thermosetting, polymeric resins. Qhov tseeb, carbon yog niaj hnub no yuav luag txhua cov ntaub ntawv sib xyaw, lub hauv paus txhawb nqa uas tau nthuav tawm hauv daim ntawv ntawm carbon fibers. Txawm li cas los xij, tib lub sijhawm, ntau yam khoom siv pabcuam tuaj yeem txuas cov ntsiab lus.

Tus nqi

Carbon yog cov khoom kim heev kawg, tus nqi uas tau txiav txim siab los ntawm kev sib koom ua haujlwm ntawm kev siv tes ua haujlwm thiab cov txheej txheem kev ua haujlwm nyuaj feem ntau. To taubcarbon kim npaum li cas, cia peb piv nws cov nqi nrog hlau. Yog li, yog tias ib kilogram ntawm cov hlau yuav raug nqi rau cov chaw tsim khoom txog $ 1, ces tib qhov hnyav ntawm carbon fiber yog 20 npaug ntau dua. Txhawm rau txo tus nqi ntawm cov pa roj carbon fiber ntau tsuas yog ua tau los ntawm kev qhia tag nrho automation ntawm cov txheej txheem ntawm nws cov creation.

Scope of application

Thaum pib, cov pa roj carbon yog cov khoom siv uas tau tsim rau lub dav hlau thiab kev lag luam tsheb. Txawm li cas los xij, dhau sijhawm, vim nws cov yam ntxwv ua tau zoo (tsis tshua muaj lub ntiajteb txawj nqus, lub zog siab), nws tau pom daim ntawv thov hauv lwm qhov chaw xws li:

- Aircraft kev lag luam.

- Tsim ntau yam khoom siv kis las, nuv ntses, kaus mom hlau.

- Tsim khoom siv kho mob thiab lwm yam.

Special Features

Kawm seb carbon yog dab tsi, cia peb nco ntsoov nws lub ntsiab zoo. Cov khoom siv los ntawm cov khoom siv no tuaj yeem ua pwm nyob rau hauv yuav luag txhua qhov kev teeb tsa. Qhov no yog vim tias lub vev xaib carbon muaj qhov hloov pauv tau yooj yim, uas, dhau los, muab kev pom zoo txiav thiab txiav. Nyob rau hauv rooj plaub no, nws yog ib qho tseem ceeb rau impregnate cov khoom tiav nrog epoxy resin. Cov khoom tau txais los ntawm txoj kev no tuaj yeem ua tau sanded, polished, pleev xim rau thiab txawm tias flexo luam tawm rau lawv yam tsis muaj teeb meem.

Qhov txawv ntawm

Txuas ntxiv los txiav txim siab seb carbon yog dab tsi (karbon) peb yuav qhia nws cov yam ntxwv tshwj xeeb. Rau txhua yam ntawm cov pa roj carbon monoxide no, kev siv cov khoom siv txhawb zog yog ib txwm muaj - carbon fibers, thickness uas yog nyob rau hauv 0,005-0.01 hli, zoo heev nyob rau hauv nro, tab sis tsis kam rau ntawm dabtsi yog khoov thiab torsion. Yog vim li cas cov pa roj carbon monoxide yog cov khoom siv hauv daim ntawv, roj hmab feem ntau yog siv los ntxiv dag zog, uas ua rau carbon fiber ntau grey tint. Feem ntau, cov pa roj carbon yog cov yam ntxwv los ntawm kev hnav tsis kam, lub zog, rigidity thiab tsis tshua muaj lub ntiajteb txawj nqus.. Nws qhov ceev yog los ntawm 1450 kg / m3. mus txog 2000 kg/m3

Subtleties of manufacturing technology

Fibers los ntawm carbon filaments tau txais hauv huab cua thaum kho cua sov. Ntawd yog, oxidation ntawm cov organic lossis polymeric threads tshwm sim thaum nruab hnub ntawm qhov kub ntawm 250 degrees Celsius. Tom qab ntawd carbonization yog nqa tawm - cua sov ntawm cov fibers tau txais nyob rau hauv ib qho inert gas ib puag ncig nyob rau hauv ib tug kub ntawm 800-1500 degrees los npaj cov qauv molecular rau qhov zoo tshaj plaws. Qhov no yog ua raws li graphitization hauv tib qhov nruab nrab, tab sis twb nyob rau ntawm qhov kub txog li 3000 degrees. Cov txheej txheem no tuaj yeem rov ua dua ob peb zaug kom nce cov pa roj carbon ntau rau 99%.

Ib daim foos

Carbon fibers tuaj yeem ua luv luv, txiav, lossis ua cov xov txuas ntxiv ntawm cov reels. Tab sis, raws li tau hais los saum no, cov pa roj carbon tsis zoo rau kev khoov, ces carbon fiber feem ntau tsim rau hauv cov ntaub ntawv hu ua Carbon Fabric. Ntxiv mus, nws hloov tawm nyob rau hauv daim ntawv ntawm ntau yam weaves: herringbone, matting, thiab hais txog. Nws tshwm sim tias cov fibers tsuas cuam tshuam ua ntej tau ntim nrog cov resin hauv cov stitches loj loj.uas carbon fibers tau muab tso rau hauv txheej. Ib daim ntawv 1 hli tuab muaj feem ntau yog peb mus rau plaub txheej.

Carbon muaj tag nrho cov txiaj ntsig uas tsis tuaj yeem lees paub, ntawm qhov peb yuav tsum taw qhia:

- Lub ntiajteb txawj nqus me me. Txawm tias txhuas yog 20% hnyav dua li cov khoom piav qhia.

- Carbon, kev sib xyaw ntawm carbon thiab Kevlar, tsuas yog me ntsis hnyav dua li roj hmab, tab sis muaj zog ntau dua, thiab nyob rau hauv qhov cuam tshuam ntawm qhov cuam tshuam tsuas yog tawg, tab sis tsis tawg rau hauv cov khoom me me.

- Resistant mus rau qhov kub thiab txias. Cov pa roj carbon tuaj yeem tiv taus txog 2000 degrees Celsius.- muaj peev xwm ua kom sov zoo thiab kev co zoo heev.

- Resistant rau qhov tshwm sim ntawm corrosion.

- Muaj lub zog tensile siab thiab lub zog tensile.

- Muaj qhov zoo nkauj thiab zoo nkauj ntxim nyiam.

Flaws

Txawm li cas los xij, piv rau cov khoom siv hlau, cov pa roj carbon muaj qhov tsis zoo:

- Siab rhiab heev rau taw tes ntse cuam tshuam.

- Qhov nyuaj ntawm kev kho dua tshiab hauv qhov xwm txheej ntawm cov chips, tawg thiab ntau qhov khawb.

- Burnout thiab fading thaum raug tshav ntuj. Tias yog vim li cas txhua yam ua los ntawm carbon fiber yog tshwj xeeb varnished los yog enamelled.

- Kev tsim khoom mus sij hawm ntev txaus ntawm cov khoom uas xav tau kev nqis peev tseem ceeb ntawm lub sijhawm.

- Teeb meem nrog kev rov ua dua thiab rov siv dua. Nyob rau hauv cov cheeb tsam ntawm kev sib cuag ncaj qha nrog hlau, nws corrosion pib, yog li ntawd, nyob rau hauv cov ntsiab lus no, khotshwj xeeb fiberglass inserts.

Kev xav ntawm cov neeg siv

Hauv kev xaus, peb sau cov kev tshuaj xyuas ntawm tib neeg txog cov khoom lag luam uas tau piav qhia hauv kab lus. Yog li cas yog carbon? Cov khoom no, raws li ntau tus neeg siv, zoo heev vim nws lub zog, tab sis tib lub sijhawm lightness. Qhov no tau txais txiaj ntsig tshwj xeeb los ntawm cov neeg nuv ntses uas tau siv cov pas nuv ntses rau lub sijhawm ntev, feem ntau yog raws li cov pa roj carbon. Tau kawg, ntxiv rau qhov no, cov pas nuv ntses zoo li no kuj zoo vim tias lawv muaj cov kav ntev, vim tias lawv kuj muaj cov yam ntxwv ntawm kev hnav tsis kam.
