Basalt Rebar
Kev piav qhia txog khoom
Basalt fiber yog ib hom khoom siv sib xyaw ua ke nrog cov resin, filler, curing agent thiab lwm yam matrix, thiab tsim los ntawm cov txheej txheem pultrusion. Basalt fiber composite reinforcement (BFRP) yog ib hom khoom siv sib xyaw ua ke tshiab ua los ntawm basalt fiber ua cov khoom siv txhawb nqa ua ke nrog cov resin, filler, curing agent thiab lwm yam matrix, thiab molded los ntawm cov txheej txheem pultrusion. Tsis zoo li cov hlau txhawb nqa, qhov ceev ntawm basalt fiber txhawb nqa yog 1.9-2.1g / cm3. basalt fiber txhawb nqa yog cov hluav taws xob tsis xeb nrog cov khoom tsis sib nqus, tshwj xeeb tshaj yog nrog kev tiv taus acid thiab alkali. Nws muaj kev kam rau siab rau qhov concentration ntawm dej hauv cement mortar thiab kev nkag mus thiab diffusion ntawm carbon dioxide, uas tiv thaiv kev xeb ntawm cov qauv pob zeb hauv qhov chaw nyuaj thiab yog li ua haujlwm los txhim kho lub zog ntawm cov tsev.
Cov yam ntxwv ntawm cov khoom
Tsis yog hlau nplaum, hluav taws xob rwb thaiv tsev, muaj zog heev, modulus ntawm elasticity siab, coefficient ntawm thermal nthuav dav zoo ib yam li cov cement concrete. Ua haujlwm tau zoo heev rau tshuaj lom neeg, ua haujlwm tau zoo rau acid, alkali, thiab ntsev.
