Daim Ntawv Thov Basalt Fiber Unidirectional Npuag Hauv Cov Haujlwm Txhawb Nqa Cov Qauv
Kev ua tau zoo tshaj plaws:
Cov fiber basaltmuaj cov khoom siv lub cev zoo heev, kev nplaum zoo, kev tiv taus cua sov thiab Kev Tiv Thaiv Kev Xeb, thiab lwm yam., Zoo heev rau kev ua haujlwm engineering.
Basalt Fiber Daim ntaub unidirectional tsis yog tsuas muaj lub zog tensile siab xwb, tab sis kuj muaj qhov zoo elongation siab (3.1%). Nws tuaj yeem nqus tau ntau lub zog los ntawm kev hloov pauv thaum nws raug rhuav tshem nyob rau hauv lub xeev txwv, yog li nws muaj kev ua tau zoo tshwj xeeb thiab zoo heev rau kev txhawb nqa av qeeg. Daim ntaub basalt fiber unidirectional yog cov khoom siv rwb thaiv tsev tsis-conductive. Hauv cov av hauv av, txoj kev tsheb ciav hlau hluav taws xob thiab qee qhov kev tiv thaiv magnetization, hluav taws xob rwb thaiv tsev, kev ua tau zoo tiv thaiv magnetic ntawm qhov project txhawb nqa lub tsev, daim ntaub basalt fiber unidirectional muaj qhov zoo heev. Ntxiv raubasalt fiber unidirectional daim ntaub Hauv kev tsim kho qhov project reinforcement kuj yooj yim heev, thiab kev sib xyaw ua ke zoo dua, cov resin impregnation permeability siab dua li cov carbon fiber, yog li txhim kho cov qauv tsev ntawm kev tiv thaiv rau kev txav mus los thiab kev cuam tshuam, tsim nyog rau kev txhawb nqa choj, mounds, kem, beams thiab lwm qhov ntawm tus choj.
Kev ua tau zoo:
1. Kev cuam tshuam tsis kam: lub zog tensile ntawm basalt fiber tas mus li ntawm 4100 ~ 4800MPa, modulus ntawm elasticity ntawm 90 ~ 110GPa, qhov kawg elongation ntawm 3.1% (carbon fiber 1.7%, spunlaced 2.4%), nyob rau hauv qhov txwv ntawm lub ntiajteb txawj nqus, cov khoom siv fiber basalt yog thawj zaug kom nqus tau ntau lub zog los ntawm kev deformation, uas yog ib qho ntawm cov khoom xav tau hauv qhov project reinforcement. Yog li ntawd, basalt fiber yog dav siv hauv cov khoom siv tub rog, cov chaw tawg-pov thawj, choj pier reinforcement project.
2. Kev tiv thaiv kev qaug zog ntawm lub zog dynamic: Txawm hais tias lub zog tensile ntawm carbon fiber siab, nws muaj kev ua tau zoo rau lub sijhawm ntev ntawm qhov chaw thauj khoom, tab sis thaum lub xeev siab tshaj plaws ntawm kev ntxhov siab carbon fiber rau kev puas tsuaj brittle, kev tiv thaiv kev qaug zog dynamic, kev tiv thaiv kev qaug zog tsis zoo li basalt fiber, yog li ntawd hauv kev txhawb nqa cov qauv, tshwj xeeb tshaj yog kev txhawb nqa choj, kev txhawb nqa tiv thaiv av qeeg. Yuav tsum siv cov ntaub ntawv sib txawv hauv ntau qhov chaw, qee qhov yuav tsum siv carbon fiber, qee qhov yuav tsum siv basalt fiber.
3. Kev tiv thaiv kua qaub, kev tiv thaiv alkali, kev tiv thaiv tshuaj lom neeg: cov khoom siv basalt fiber composite muaj kev tiv thaiv kua qaub thiab kev tiv thaiv alkali zoo, hauv 1000C hauv Ca (OH) 2 saturated kua impregnated rau 4 teev, lub zog monofilament khaws cia tus nqi ntau dua 75.8% lossis ntau dua, kev tiv thaiv alkali muaj zog, kev tiv thaiv acid zoo. Vim yog cov chlorine ions ntawm dej hiav txwv ntawm ntug dej hiav txwv, chaw nres nkoj qhov chaw nres nkoj cov qauv pob zeb muaj kev xeb tshuaj muaj zog, tuaj yeem ua rau carbonization ntawm pob zeb, kev xeb ntawm cov hlau reinforcing, yog li kev siv cov basalt fiber composite tendons, daim ntaub unidirectional rau kev txhawb nqa tuaj yeem ua tiav cov txiaj ntsig zoo dua.
4. Cov khoom siv hluav taws xob zoo rwb thaiv tsev: Cov fiber basalt Kev rwb thaiv tsev zoo dua li alkali iav fiber, carbon fiber yog tus neeg coj hluav taws xob, yog li ntawd hauv qhov project subway, qhov project tunnel, qhov project hluav taws xob, cov nroj tsuag kev lag luam, cov kev xav tau rwb thaiv tsev ntawm cov tsev siab, kev siv cov fiber basalt reinforcement tuaj yeem tshem tawm cov xwm txheej tiv thaiv.
Tus nqi kom zoo dua:
Basalt fiber unidirectional daim ntaub Hauv kev siv cov qauv kev txhawb nqa hauv kev siv kev ua tau zoo ib nrab ua tau raws li lossis tshaj qhov xwm txheej ntawm cov roj carbon fiber, ib square meter basalt fiber unidirectional daim ntaub tus nqi yog qhov kawg ntawm 1 / 4-1 / 3, yog qhov pheej yig tshaj plaws rau carbon fiber unidirectional daim ntaub.
