Dab tsi yog cov yam ntxwv tseem ceeb ntawm cov kav dej fiberglass?

1. Zoo corrosion kuj. Txij li cov ntaub ntawv tseem ceeb ntawm FRP yog tsim los ntawm unsaturated polyester resin thiab iav fiber ntau nrog cov ntsiab lus siab polymer, nws tuaj yeem tiv taus corrosion ntawm acid, alkali, ntsev thiab lwm yam xov xwm, nrog rau cov dej phwj hauv tsev tsis zoo, corrosive av, cov dej khib nyiab thiab lwm yam. ntau chemical kua. Kev yaig, feem ntau, tuaj yeem ua haujlwm ruaj ntseg rau lub sijhawm ntev.

2. Zoo aging kuj thiab tshav kub tsis kam. Cov iav fiber ntau lub raj tuaj yeem siv tau ntev hauv qhov kub thiab txias ntawm -40 ℃ ~ 70 ℃, thiab kub resistant resin nrog cov mis tshwj xeeb kuj tuaj yeem ua haujlwm ib txwm nyob rau qhov kub siab tshaj 200 ℃.

3. Kev ua haujlwm zoo antifreeze. Hauv qab rho tawm 20 ℃, lub raj yuav tsis khov tom qab khov.

4. Lub teeb yuag thiab siab zog. Cov txheeb ze ntom ntom yog nyob nruab nrab ntawm 1.5 thiab 2.0, uas tsuas yog 1/4 txog 1/5 ntawm cov pa roj carbon steel, tab sis lub zog tensile nyob ze los yog ntau tshaj ntawm cov hlau, thiab lub zog tshwj xeeb tuaj yeem muab piv nrog cov high-qib alloy steel. Yog li ntawd, nws muaj txiaj ntsig zoo hauv aviation, foob pob hluav taws, lub dav hlau, cov hlab ntsha siab thiab lwm yam kev siv uas yuav tsum tau txo qhov hnyav.

5. Zoo tsim.

Ntau yam khoom siv tuaj yeem hloov kho kom haum raws li qhov yuav tsum tau siv, uas tuaj yeem ua rau cov khoom muaj kev ncaj ncees.

6. Zoo hnav tsis kam. Cov dej uas muaj ntau cov av nkos, xuab zeb thiab pob zeb tau muab tso rau hauv cov yeeb nkab kom ua tiav qhov kev sib piv ntawm cov txiaj ntsig ntawm kev sib hloov hnav. Tom qab 3 lab rotations, hnav qhov tob ntawm sab hauv phab ntsa ntawm lub raj kuaj pom muaj raws li hauv qab no: 0.53mm rau cov raj steel coated nrog tar thiab enamel, 0.52mm rau cov raj steel coated nrog epoxy resin thiab tar, thiab iav steel raj rau. Qhov saum npoo-hardened steel raj yog 0.21mm. Yog li ntawd, FRP muaj kev hnav zoo.

7. Zoo hluav taws xob thiab thermal rwb thaiv tsev. FRP yog ib qho tsis yog tus neeg xyuas pib, qhov hluav taws xob rwb thaiv tsev ntawm cov kav xa dej yog qhov zoo heev, thiab cov rwb thaiv tsev yog 1012-1015Ω.cm. Nws yog qhov tsim nyog rau lub zog kis, kev sib tham hauv xov tooj kab ntom ntom thiab ntau yam minefields. Lub tshav kub hloov coefficient ntawm FRP tsawg heev, tsuas yog 0.23, uas yog ib txhiab ntawm cov hlau. Tsib tawm ntawm tsib, lub raj xa dej muaj cov thermal rwb thaiv tsev zoo heev.

1. Kev sib txhuam me me thiab siab conveying muaj peev xwm. Sab hauv phab ntsa ntawm FRP yeeb nkab yog du heev, thiab qhov roughness thiab kev sib txhuam tsis kam yog tsawg heev. Qhov zoo tshaj plaws roughness yog 0.0084, thaum tus nqi n yog 0.014 rau cov kav dej ua vaj tse thiab 0.013 rau cov kav hlau cam.
