Cov roj carbon fiber tau txais koob meej hauv kev tsim cov tsheb kauj vab, dav hlau, thiab txawm tias qee lub tsheb vim tias nws ob leeg khov kho thiab hnyav. Thaum cov khoom tsim los ntawm cov roj carbon fiber feem ntau kim heev, koj tuaj yeem ua qee yam khoom siv fiber ntau hauv tsev rau ib feem ntawm tus nqi ntawm cov khw muag khoom ib txwm muaj. Koj tsuas yog yuav tsum tsim cov pwm zoo, siv cov roj carbon fiber, thiab ua kom tiav ib feem thaum nws qhuav.
Cov kauj ruam
Txoj Kev 1 ntawm 4: Tsim Kom Zoo
Kauj Ruam 1. Nrhiav tus pwm tsim nyog
Ua ntej koj tuaj yeem pib ua qee yam los ntawm cov pa roj carbon fiber, koj yuav tsum muaj pwm. Cov pwm tsim cov pa roj carbon rau hauv daim ntawv uas koj xav tau. Koj tuaj yeem yuav cov pwm online, lossis ntawm lwm lub khw muag khoom. Cov pa roj carbon fiber ntau tau nrov nyob rau hauv kev lag luam tsheb thiab maus taus, thiab feem ntau koj tuaj yeem yuav cov pwm los ntawm cov neeg siv khoom.
Qee qhov xwm txheej, koj tuaj yeem siv qhov qub ua ib qho pwm los ua cov pa roj carbon. Qhov no yuav tsis ua haujlwm zoo yog tias ib feem puas
Kauj Ruam 2. Hnav cov cuab yeej tiv thaiv tsim nyog thaum ua haujlwm nrog cov pa roj carbon fiber
Yam tsawg kawg, koj yuav tsum hnav hnab looj tes tiv thaiv, tsom iav, thiab daim npog ntsej muag. Cov iav no yuav pab tiv thaiv kev nqus cov pa uas ua rau tuag taus lossis nqus tau cov kuab tshuaj phem los ntawm daim tawv nqaij. Ntxiv nrog rau lub iav, ua haujlwm hauv thaj chaw uas muaj cua nkag tau zoo kom tsis txhob muaj roj ntau dhau.
Kauj Ruam 3. Npaj pwm
Ua ntej yuav pib, pwm yuav tsum tau txau nrog cov khoom siv uas tso cai rau ib feem cais los ntawm cov pwm thaum nws ua tiav. Cov ntaub ntawv no feem ntau yog hom tshwj xeeb ntawm cov ciab uas tsis cuam tshuam nrog cov txheej txheem kho ntawm ib feem. Koj tuaj yeem xaj cov roj nplua nyeem hauv online lossis yuav ib qho los ntawm cov khw muag khoom siv roj carbon fiber.
Cov ciab yuav tsum tsis txhob meej pem nrog cov tshuaj. Cov ciab tsim ib txheej nruab nrab ntawm cov pwm thiab cov cob, thiab tsis tawv
Kauj Ruam 4. Tsuag sab hauv nrog cov kua nplaum
Kom tau txais txiaj ntsig zoo tshaj plaws, xyuas kom tseeb tias txhua lub nooks thiab crannies ntawm cov pwm tau ua tiav nrog cov kua nplaum. Nyob ntawm qhov loj me ntawm cov pwm, koj yuav xav tau ntau lub kaus poom ntawm cov yas Qhov no yuav tsim cov nplaim uas xav tau los siv cov roj carbon fiber.
Tsis zoo li cov ciab, cov kua nplaum yuav tawv thiab raug tshem tawm ntawm cov pwm ua ib feem ntawm cov pa roj carbon
Txoj Kev 2 ntawm 4: Tso Cov Carbon Fiber
Kauj Ruam 1. Thov siv daim ntaub fiber
Ceev nrooj nias cov ntawv ntawm cov pa roj carbon fiber mus rau hauv pwm. Ib yam li siv cov tshuaj pleev, ua kom ntseeg tau tias koj npog tag nrho cov seem ntawm cov pwm sab hauv nrog cov ntaub fiber ntau. Yog tias muaj cov fab lossis cov ces kaum me me tshwj xeeb, koj yuav xav txiav txim siab nias cov ntaub fiber ntau rau hauv cov crannies nrog tus ntsia hlau lossis lwm yam cuab yeej me me.
Kauj Ruam 2. Ntxiv cov tshuaj ntxiv
Tsuag sab hauv ntawm cov pwm nrog cov tshuaj ntxiv. Daim ntaub fiber ntau yuav tsum tau ua kom tiav nrog cov kua. Qhov no yog qhov sib txuas cov fibers ntawm daim ntaub ua ke thiab muab carbon fiber nws lub zog.
Kauj Ruam 3. Hnab pwm
Txhawm rau zam cov av thiab hmoov av poob rau hauv cov tshuaj thiab kom tau cov ntaub fiber ntau kom ua tau zoo dua rau cov pwm, koj tuaj yeem ntim cov pwm. Qhov no txhais tau tias muab lub hnab ntim rau saum cov pwm nrog lub tshuab nqus tsev txuas. Tom qab ntawd, siv lub tshuab nqus tsev (lossis rau lub tshuab nqus tsev nqus nqus nqus nqus dej) kom rub nqus ntawm lub hnab. Qhov no tseem yuav pab kom cov tshuaj qhuav sai dua.
Kauj Ruam 4. Ua kom sov cov roj carbon fiber
Cua sov cov pa roj carbon fiber ib feem yuav ua kom cov txheej txheem ua kom huv. Koj yuav tsum ua kom sov ib nrab ntawm 250 ° F (121 ° C) thiab 350 ° F (177 ° C) li ob peb teev. Xwb, koj tuaj yeem tso cai rau kho qhov qeeb qeeb yam tsis muaj cua sov. Qhov no feem ntau yuav siv sijhawm tsawg kawg 24 teev.
- Cov resins feem ntau yuav tsis kho zoo hauv qab 60 ° F (16 ° C).
- Koj yuav tsum tsis txhob kho qhov feem hauv lub qhov cub ua noj. Cov pa taws muab tawm tsw ntxhiab thiab lawv muaj tshuaj lom. Koj xav tau autoclave lossis lwm qhov cua sov rau cov txheej txheem tua.
Txoj Kev 3 ntawm 4: Tiav Tshooj
Kauj Ruam 1. Thov siv tsawg kawg peb txheej ntxiv ntawm cov yas
Cov txheej txheej ntawm cov pob zeb no yog txhawm rau txhim kho qhov zoo ntawm ib feem, tsis yog lub zog lossis kev ua haujlwm. Tso cai rau txhua txheej txheej los teeb ua ntej tso rau txheej tom ntej. Qhov no tuaj yeem siv qhov twg los ntawm ob peb feeb mus rau ntau teev, tab sis koj yuav tuaj yeem qhia vim tias cov kua nplaum yuav tau txhaws (nplaum) thaum nws tau npaj rau lub tsho tom ntej.
Kauj Ruam 2. Xuab txheej txheej txheej sab saum toj
Thaum koj tau thov peb txog rau xya txheej ntawm cov yas, nws yog lub sijhawm los xuab zeb nws. Koj yuav tsum xuab zeb tawm ib qho tsis zoo hauv cov tshuaj, zoo li cov hmoov av lossis cov npoo tsis sib xws. Saib xyuas kom tsis txhob hla cov tshuaj, yog tias koj xuab zeb cov fibers hauv qab koj yuav rhuav tshem ib feem.
Kauj Ruam 3. Ua ntu ntu
Tom qab koj tau xuab zeb qhov ua tsis tiav tawm ntawm cov tshuaj, koj tuaj yeem txhuam nws. Koj tuaj yeem yuav cov tshuaj txhuam kom tsim nyog rau koj cov tshuaj ntawm tib lub khw muag khoom uas koj tau yuav cov tshuaj. Siv cov tshuaj txhuam kom huv, ntaub mos muag, thiab so nws nrog lwm daim ntaub huv, mos mos. Qhov no yuav muab qhov ci zoo nkauj.
Kauj Ruam 4. Tshawb xyuas cov pa roj carbon fiber ib feem ntawm txhua sab
Nco ntsoov tias tsis muaj kab nrib pleb lossis lwm yam deformations ntawm ib feem. Yog tias ib feem puas, koj yuav tau pib dua thiab ua lwm qhov. Yog tias koj tsis pom ib qho tsis xws luag, koj tuaj yeem siv ib feem.
Txoj Kev 4 ntawm 4: Tsim Cov Khoom Siv Hluav Taws Xob Hauv Lub Tshuab
Kauj Ruam 1. Tua cov tshuaj ua ntej
Precursor yog cov khoom siv uas koj siv los ua cov pa roj carbon fiber. Yuav luag txhua cov roj carbon fiber yog tsim los ntawm polyacrylonitrile ua ntej. Koj yuav tsum yaj cov polyacrylonitrile hauv cov kuab tshuaj organic xws li dimethyl sulfoxide.
Kauj Ruam 2. Spin cov polymer
Thaum cov txheej txheem ua ntej yaj, koj muab tso rau hauv da dej coagulation. Tom qab ntawd, khiav lub slush hla lub spinneret. Cov khoom siv raug yuam los ntawm lub qhov zoo ntawm lub spinneret los tsim cov hlua ntev.
Kauj Ruam 3. Ntxiv cov pa
Cov pa xav tau txhawm rau txhawm rau hla cov polymers thiab ua rau lawv haum rau cov fibers. Txhawm rau oxidize cov hlua, ua kom sov lawv hauv qhov cub oxidation uas nyob ntawm 200 ° C (392 ° F) txog 300 ° C (572 ° F). Koj yuav tsum tuav cov pa kom tsim nyog thaum lub sijhawm txheej txheem no kom tsis txhob raug cov hlua hluav taws hlawv.
Kauj Ruam 4. Pyrolyze cov saw hlau polymer
Thaum oxidized, cov hlua yuav tsum tau muab rhaub hauv qhov chaw tsis muaj oxygen. Txij li thaum tsis muaj oxygen, cov hlua yuav tsis hlawv. Hloov chaw, lawv tau ua tus txheej txheem hu ua pyrolysis, uas tshem tawm yuav luag txhua yam tsis huv, xws li cov kuab tshuaj organic. Cov txheej txheem pyrolysis tau siv ntau qhov twg los ntawm 700 ° C (1, 292 ° F) txog 1, 500 ° C (2, 730 ° F).
Kauj Ruam 5. Kho cov fibers
Pyrolysis tawm koj nrog cov pa roj carbon fiber ntau. Ua ntej xa mus rau cov neeg siv khoom lossis ua cov nroj tsuag, cov xov yuav tsum tau kho. Qhov no suav nrog etching cov fibers nrog cov kua qaub, xws li nitric acid. Tom qab etching (xa mus rau kev kho mob) cov fiber ntau yog txheej txheej txheej hu ua sizing. Cov txheej txheej ua kom cov fibers loj dua thiab ua rau lawv muaj zog ntxiv rau kev ua thiab cov neeg siv khoom siv.
