Tau ntau xyoo los lawm, kev siv hlau los ua vaj tse yog ib yam khoom siv tseem ceeb hauv kev lag luam tsim kho. Txawm li cas los xij, ntau cov ntaub ntawv qhia tias yog tias cov qauv pob zeb ua vaj tse tsis zoo lossis qhov chaw nyob tsis zoo, kev ruaj khov thiab kev ua haujlwm ntawm cov hlau yuav raug cuam tshuam. Muaj ntau tus kws tshawb fawb Suav thiab txawv teb chaws tau xaus lus tias kev siviav fiber composite reinforcementKev hloov cov hlau txhawb zog hauv cov teb tshwj xeeb yog ib txoj hauv kev zoo los daws qhov teeb meem no. Cov iav fiber sib xyaw ua ke txhawb zog yog ib hom khoom sib xyaw tshiab uas tsim los ntawm pultrusion thiab kev kho tshwj xeeb saum npoo, siv cov iav fiber filaments ua kev txhawb zog, epoxy resin ua cov khoom siv matrix, thiab suav nrog cov neeg sawv cev pabcuam tsim nyog (xws li crosslinking monomers, initiators, accelerators, alteration agents, flame retardants, polymerization inhibitors, fillers, pigments, thiab lwm yam).
1. Cov yam ntxwv ntawm Cov Iav Fiber Composite Reinforcement
(1) Lub Zog Tensile Siab: Lub zog tensile ntawm cov iav fiber reinforcement zoo dua li ntawm cov hlau reinforcement ib txwm muaj, tshaj qhov ntawm cov hlau reinforcement ntawm tib qhov kev qhia tshwj xeeb los ntawm 20%, thiab nws kuj muaj kev tiv thaiv kev qaug zog zoo.
(2) Lub teeb yuag: Qhov hnyav ntawm cov iav fiber reinforcement tsuas yog 1/4 ntawm qhov ntawm cov hlau reinforcement ntawm tib lub ntim, nrog rau qhov ceev ntawm 1.5 thiab 1.9 (g / cm3). (3) Kev tiv thaiv corrosion muaj zog: Tiv taus corrosion los ntawm acids, alkalis, thiab lwm yam tshuaj lom neeg; tiv taus kev yaig los ntawm chloride ions thiab cov tshuaj pH qis, tshwj xeeb tshaj yog muaj zog tiv taus cov pa roj carbon thiab cov tshuaj chlorine.
(3) Kev sib txuas ntawm cov khoom siv muaj zog: Tus coefficient ntawm thermal expansion ntawm cov iav fiber reinforced concrete yog ze rau qhov ntawm cement dua li ntawm cov hlau, ua rau muaj kev sib txuas ntawm cov iav fiber reinforced concrete thiab cov pob zeb.
(4) Kev yooj yim tsim qauv siab: Cov iav fiber reinforced concrete muaj qhov ruaj khov elastic modulus thiab qhov loj me ruaj khov nyob rau hauv kev ntxhov siab thermal. Nws tuaj yeem khoov thiab tsim rau hauv txhua yam duab, muaj kev nyab xeeb zoo, tsis conductive, tsis muaj hluav taws xob, nplaim taws-retardant, thiab anti-static. Nrog kev hloov pauv hauv cov mis, nws yuav tsis tsim hluav taws xob thaum sib tsoo nrog cov hlau.
(6) Muaj zog permeability magnetic: Cov iav fiber reinforced concrete yog cov khoom siv tsis muaj magnetic, tshem tawm qhov xav tau kev kho demagnetization hauv cov khoom tsis muaj magnetic lossis electromagnetic.
(7) Kev tsim kho yooj yim: Cov iav fiber reinforced concrete tuaj yeem tsim tau ntau yam khoom txheem thiab tsis txheem nrog ntau qhov sib txawv thiab qhov ntev raws li tus neeg siv xav tau. Kev khi ntawm qhov chaw tuaj yeem ua tiav los ntawm kev siv cov hlua khi uas tsis yog hlau, ua rau kev ua haujlwm yooj yim.

Cov khoom siv fiberglass composite reinforcement ua rau muaj kev tiv thaiv xeb zoo heev, tshwj xeeb tshaj yog thaum muaj kev tiv thaiv siab rau cov tshuaj pH thiab cov tshuaj corrosive. Txawm hais tias nyob rau hauv qhov chaw raug tshav ntuj, thaj chaw ntub dej nag lossis qhov chaw noo noo, cov khoom siv fiberglass composite reinforcement ua rau muaj kev tiv thaiv xeb zoo hauv kev ua liaj ua teb thiab feem ntau muaj lub neej ua haujlwm ntev dua li cov khoom siv hlau ib txwm muaj.
2. Daim Ntawv Thov Fiberglass Composite Reinforcement hauv Kev Ua Liaj Ua Teb
(1) Kev ua laj kab tiv thaiv tub sab tau siv dav hauv kev ua liaj ua teb ntev. Kev ua laj kab ib txwm siv cov hlau txhawb nqa ua cov pas nrig txhawb nqa, tab sis kev siv sab nraum zoov ntev ua rau xeb thiab ua tsis tiav ntawm cov hlau txhawb nqa. Qhov kev tiv thaiv corrosion muaj zog ntawm fiberglass composite reinforcement ua rau nws tsim nyog heev los hloov cov hlau txhawb nqa ua cov pas nrig txhawb nqa.
(2) Kev muab kev txhawb nqa rau cov ntoo thaum lawv loj hlob yog qhov tseem ceeb. Cov pas nrig txhawb nqa ib txwm muaj feem ntau yog ua los ntawm ntoo thiab hlau, tab sis xeb thiab laus tshwm sim thaum siv ntev, ua rau cov pas nrig txhawb nqa tsis ua haujlwm hauv huab cua hnyav.Fiberglass composite reinforcementtsis yog tsuas yog lub teeb yuag thiab muaj zog xwb tab sis kuj muaj kev tiv thaiv corrosion zoo, ua rau nws yog ib yam khoom tsim nyog heev los hloov cov ntoo thiab hlau txhawb nqa rods.
(3) Cov thav duab txhawb nqa rau cov tsev cog khoom ua liaj ua teb feem ntau yog ua los ntawm ntoo thiab hlau. Vim yog qhov kub thiab av noo ntawm ib puag ncig, cov thav duab txhawb nqa ua los ntawm ntoo thiab hlau yuav laus thiab xeb, ua rau muaj kev phom sij rau kev nyab xeeb. Cov khoom siv fiberglass composite reinforcement tuaj yeem tsim thiab tsim ua cov thav duab txhawb nqa ntawm ntau hom qauv thiab cov lus qhia raws li qhov yuav tsum tau siv. Nws tuaj yeem ntsia ncaj qha rau ntawm qhov chaw, tsis hnyav, thiab yooj yim heev rau kev tsim kho; cov khoom siv nws tus kheej kuj tiv taus xeb thiab tiv thaiv kev laus. Xav txog ob qho tib si kev nyab xeeb thiab kev txuag hluav taws xob, cov khoom siv fiberglass composite reinforcement yog qhov tsim nyog heev ua cov qauv txhawb nqa tsev cog khoom.
(4) Thaum lub sijhawm loj hlob ntawm cov txiv hmab txiv ntoo thiab zaub, cov thav duab txhawb nqa yog qhov tseem ceeb rau lawv txoj kev loj hlob zoo dua. Cov thav duab txhawb nqa ib txwm muaj feem ntau yog ua los ntawm ntoo thiab hlau, tab sis vim lawv lub zog qis, lawv yooj yim laus thiab xeb hauv cov chaw noo noo. Thaum cov txiv hmab txiv ntoo thiab zaub loj hlob thiab ncav cuag qee qhov hnyav, cov thav duab txhawb nqa yuav tawg. Fiberglass composite reinforcement muaj cov yam ntxwv ntawm kev sib dua, muaj zog siab, thiab tiv taus corrosion, ua rau nws tsim nyog heev los hloov ntoo thiab hlau ua cov thav duab txhawb nqa rau cov txiv hmab txiv ntoo thiab zaub.
3. Xaus LusFiberglass sib xyaw ua keKev txhawb zog ua ke cov khoom siv kho tshuab, lub cev, thiab tshuaj lom neeg zoo heev ntawm epoxy resin thiab fiberglass, thiab siv dav los daws qhov teeb meem xeb ntawm cov hlau hauv cov chaw siv tshwj xeeb. Nws cov nqi tsim nyog zoo, kev tsim kho yooj yim, thiab kev tiv thaiv xeb zoo heev tau ua rau nws maj mam hloov hlau thiab nyob hauv thaj chaw ua liaj ua teb, ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev lag luam hauv tebchaws.
