Yuav ua li cas rau kev laus ua haujlwm ntawm cov khoom siv fiber ntau?
Cov khoom siv roj carbon fiber ntau tau nrov heev vim lawv qhov zoo ntawm lub teeb. Hauv kev siv cov tswv yim, cov khoom siv carbon fiber ntau yog siv rau hauv ntau qhov chaw, txhua qhov sib txawv ntawm daim ntawv thov thiab cov qauv kev ua haujlwm. Ntawm cov no, kev laus tiv thaiv yog ib qho kev txhawj xeeb tshwj xeeb, tshwj xeeb tshaj yog rau cov khoom siv carbon fiber uas siv rau hauv qhov chaw hnyav. Kab lus no yuav tham txog kev laus ua haujlwm ntawm cov khoom siv fiber ntau.
Muaj peb yam uas cuam tshuam rau kev laus ntawm cov khoom siv fiber ntau: hnub ci, tshav kub, thiab qhov chaw ntub dej.
Hnub ci raug yog qhov tseem ceeb ntawm kev laus hauv cov khoom siv carbon fiber. Nyob rau hauv tshav ntuj, ob qho tib si pom lub teeb thiab ultraviolet rays tau yooj yim absorbed los ntawm cov polymers nyob rau hauv carbon fiber cov khoom, ua rau lub kub nyob rau hauv cov cheeb tsam ntawm absorbed nce. Qhov no ua rau oxidation, ua rau kev laus, uas txhais tau hais tias cov resin undergoes oxidative catalysis. Yog li ntawd, yog tias cov khoom siv carbon fiber tau raug tshav ntuj sab nraum zoov rau lub sijhawm ntev, yuav tsum tau them nyiaj rau cov cim ntawm kev laus.
Thaum tshav kub kub kuj yog ib qho tseem ceeb ua rau kev laus. Ib yam li lub hnub ci raug tshav kub thiab ua rau muaj kev laus, qhov kub thiab txias ib puag ncig uas siv cov khoom siv fiber ntau tuaj yeem ua rau oxidation ntawm polymer matrix, uas ua rau crosslinking thiab degradation, nrog rau hydrolysis, alcoholysis, thiab amine tshua. Txawm hais tias qhov thermal expansion thiab contraction coefficient ntawm cov ntaub ntawv carbon fiber tsawg, qhov ntev raug rau qhov kub thiab txias tom qab txias tuaj yeem tsim kev ntxhov siab sab hauv, ua rau kev laus thiab qaug zog.
Cov chaw ntub dej kuj tseem tuaj yeem ua rau kev laus ntawm cov khoom siv fiber ntau. Hauv cov huab cua ntub thiab kub lossis cov chaw ntug dej hiav txwv nrog cua ntsev, kev laus tuaj yeem tshwm sim sai dua, ua qhov no yog qhov tseem ceeb. Hloov pauv, thaj chaw huab cua thiab sab hauv av yuav tsis ua rau muaj kev txhawj xeeb ntau txog kev laus.
Zuag qhia tag nrho, cov khoom siv carbon fiber ntau pom muaj kev tiv thaiv kev laus, feem ntau cuam tshuam los ntawm peb yam. Txhawm rau daws qhov teeb meem no zoo dua, siv cov txheej txheem tiv thaiv ntawm qhov chaw tuaj yeem txhim kho cov teebmeem kev laus, ua kom cov txheej txheem kev laus ntawm cov khoom siv fiber ntau. Lawm, kev laus ntawm cov khoom siv fiber ntau yog qhov qeeb, thiab lawv lub neej kev pab cuam ntev heev, yog li tsis tas yuav txhawj xeeb txog lawv deteriorating yooj yim. Tsis tas li ntawd, siv cov ntaub ntawv zoo-aging-resistant resin raws li matrix tuaj yeem txhim kho qhov zoo ntawm kev laus tiv thaiv. Yog tias koj muaj lus nug, thov hu rau kuv!
