Txhais cov yam ntxwv tseem ceeb ntawm iav fiber ntau hauv kev nthuav dav

1. corrosion kuj zoo.

Txij li cov ntaub ntawv tseem ceeb ntawm iav fiber reinforced yas yog tsim los ntawm unsaturated polyester resin thiab iav fiber ntau, nws tuaj yeem tiv thaiv corrosion ntawm acid, alkali, ntsev thiab lwm yam xov xwm, nrog rau cov dej phwj tuaj hauv tsev, corrosive av, tshuaj khib nyiab thiab ntau yam. chemical kua. Nyob rau hauv ib txwm muaj xwm txheej, nws tuaj yeem tswj xyuas kev nyab xeeb rau lub sijhawm ntev.

2. 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 siab tshaj ntawm cov hlau, thiab lub zog tshwj xeeb yog piv rau qhov siab. -qib alloy steel. Yog li ntawd, nws muaj txiaj ntsig zoo hauv aviation, foob pob hluav taws, chaw tsheb, cov hlab ntsha siab, thiab lwm yam khoom uas yuav tsum tau txo lawv tus kheej qhov hnyav.

3. Zoo hluav taws xob thiab thermal rwb thaiv tsev. FRP yog ib qho tsis yog tus coj, thiab cov hluav taws xob rwb thaiv tsev ntawm cov kav dej yog qhov zoo heev. Lub rwb thaiv tsev tsis kam yog 1012-1015Ω.cm. Nws yog qhov tsim nyog tshaj plaws rau kev siv hauv kev xa hluav taws xob, kev sib txuas lus kab ntom ntom thiab thaj chaw mine. Lub tshav kub hloov pauv coefficient ntawm FRP tsawg heev, tsuas yog 0.23, uas yog 1000 Fifthly, lub raj xa dej tau zoo heev thermal rwb thaiv tsev.

4. Zoo tsim.

Ntau yam khoom lag luam tuaj yeem hloov kho kom haum raws li qhov yuav tsum tau siv, thiab cov khoom tuaj yeem muaj kev ncaj ncees.

5. Zoo Frost tsis kam.

Hauv qab qhov ntsuas kub ntawm 20 ° C, yuav tsis muaj qhov tawg hauv lub raj tom qab khov.

6. Tsis tshua muaj kev sib txhuam tsis kam thiab siab conveying muaj peev xwm. Lub puab phab ntsa ntawm cov iav steel yeeb nkab yog du heev, nrog tsawg roughness thiab kev sib txhuam tsis kam. Lub roughness coefficient yog 0.0084, thaum lub n tus nqi ntawm cov yeeb nkab yog 0.014, thiab tus nqi ntawm cam khwb cia hlau yeeb nkab yog 0.013.

7. Kev ua haujlwm zoo los tiv thaiv kev laus thiab kev ua haujlwm kub.

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

8. Zoo hnav tsis kam.

Muab cov dej uas muaj cov av nkos thiab cov xuab zeb ntau ntau rau hauv cov yeeb nkab los ua qhov kev sim sib piv ntawm qhov cuam tshuam ntawm kev sib hloov puas. Tom qab 3 lab rotations, hnav qhov tob ntawm cov phab ntsa sab hauv ntawm lub raj tshuaj ntsuam xyuas yog raws li hauv qab no: cov yeeb nkab steel coated nrog tar thiab enamel yog 0.53 hli, cov yeeb nkab steel coated nrog epoxy resin thiab tar yog 0.52 hli, thiab cov yeeb nkab steel nrog. nto hardening kho yog iav steel yeeb nkab Nws yog 0.21mm. Yog li ntawd, FRP muaj kev hnav zoo.
