Dab tsi yog cov khoom ntawm fiberglass raj?

1. Corrosion kuj

Cov iav fiber ntau lub raj muaj kev tiv thaiv corrosion zoo heev, thiab tuaj yeem tiv thaiv corrosion ntawm ntau yam roj thiab kua xov xwm xws li acid, alkali, organic hnyav, ntsev, thiab lwm yam. Nws yeej yuav tsis xeb. Raws li hom nruab nrab thiab qhov kub thiab txias ntawm lub sijhawm siv tiag tiag, o-phenyl, m-phenyl thiab vinyl tuaj yeem xaiv.

2. Lub teeb yuag thiab siab zog

Cov iav fiber ntau cov ntsiab lus ntawm cov iav fiber ntau yog siab dua li lwm cov txheej txheem sib xyaw ua ke, yog li nws lub zog ntev yog sib npaug rau cov hlau. Qhov ntom ntawm cov raj puag ncig tsuas yog kwv yees li ib feem peb ntawm cov hlau, thiab nws lub zog tshwj xeeb yog siab dua li cov hlau. Lub modulus ntawm round raj yog qis dua cov hlau, feem ntau tsuas yog 1/7-1/10 ntawm cov hlau.

3. Los tiv thaiv kev laus

Lub fiberglass raj txais cov khoom zoo thermosetting resin thiab fiberglass system. Nws txawv ntawm cov thermoplastics dav dav. Lub neej ua haujlwm ib txwm muaj ntawm cov khoom tuaj yeem ncav cuag 20 xyoo. Kev tiv thaiv kev laus tuaj yeem tau txais los ntawm kev ntxiv cov tshuaj tiv thaiv ultraviolet thiab polyester xav.

4. Yooj yim rau tswj

Fiberglass raj yog tsim los ntawm kev sib xyaw xim rau hauv cov cob. Cov khoom xim tuaj yeem hloov kho arbitrarily raws li cov neeg siv khoom xav tau. Nws tsis yooj yim rau ploj, tsis tas yuav tsum tau pleev xim rau, thiab muaj kev tu tus kheej.

5. Cov khoom siv hluav taws xob zoo heev

Cov iav fiber ntau lub raj muaj cov hluav taws xob rwb thaiv tsev zoo, tsis muaj hluav taws xob thiab hluav taws xob, thiab tuaj yeem siv rau hauv qhov chaw muaj kev phom sij, cov khoom siv hlau nplaum sib nqus thiab qhov chaw tawg thiab tawg.

6. Cov khoom cua sov

Fiberglass yeeb nkab yog ib yam khoom siv thermal rwb thaiv tsev. Nws thermal expansion coefficient yog qis dua li ntawm cov yas. Pultrusion muaj cov cuab yeej zoo heev ntawm qhov kub thiab txias thiab yuav tsis yaj ntawm qhov kub, tab sis nws lub zog thiab cov qauv yuav txo qis rau qee qhov ntawm qhov kub thiab txias. Qhov ntsuas kub ntawm cov raj puag ncig yog feem ntau -50 txog 100 ° C.
