Fiberglass Sleeve Underwater Corrosion Reinforcement Technology

Lub tes tsho iav fiberKev siv tshuab tiv thaiv xeb hauv qab dej yog kev sib xyaw ua ke ntawm cov thev naus laus zis hauv tsev thiab txawv teb chaws thiab ua ke nrog Tuam Tshoj lub teb chaws cov xwm txheej, thiab kev pib ntawm thaj chaw ntawm cov cuab yeej siv hydraulic concrete anticorrosion reinforcement.

Cov thev naus laus zis muaj cov yam ntxwv tseem ceeb hauv qab no:

1. tuaj yeem tiv taus lub voj voog huab cua los ntawm qhuav thiab ntub, kub thiab txias, khov thiab yaj thiab lwm yam kev sib cuam tshuam, thiab cov dej ntws, dej hiav txwv, dej khib nyiab, electrolytes thiab lwm yam kev cuam tshuam corrosive lossis tsis tu ncua, kev ruaj khov zoo heev.

2. Vim yog qhov inertia ntawm lub tes tsho fiberglass rau cov tshuaj tiv thaiv, nws tuaj yeem tiv taus txhua yam tshuaj lom neeg, thiab nws muaj zog tiv taus cov kua qaub thiab alkali, yog li nws tuaj yeem tiv taus qhov xeb ntawm dej hiav txwv.

3. Vim tias nws tsis rhiab rau dej, nws tseem muaj lub zog sib txuas zoo heev (lub zog sib txuas txog li 2.5MPa) hauv kev tsim kho hauv qab dej. Tshwj xeeb tshaj yog nyob rau hauv "kev tsim kho hauv qab dej", tsis tas yuav tsim cov cofferdams thiab cov khoom siv ntws dej kim, yog ib txheej ntawm cov txheej txheem tiv thaiv xeb zoo tshaj plaws uas txuag sijhawm, ua haujlwm-txuag, thiab txuag nyiaj.

4. Cov grout tiv thaiv kev tawg hauv qab dej thiab cov grout epoxy tuaj yeem nkag mus rau hauv cov kab nrib pleb ntawm lub substrate, tsim cov qauv rivet, kho zoo dua thiab txhawb nqa cov qauv qub.

Cov Iav Fiber Tshwj Xeeb Tes Tsho:

Tshwj xeebLub Tes Tsho Fiber Iavyog ib yam khoom siv tshiab ua los ntawm cov khoom siv hluavtaws thiab cov iav fiber los ntawm cov txheej txheem sib xyaw. Nws yog ib yam khoom siv thermosetting polymer nrog cov yam ntxwv hauv qab no:

Lub teeb yuag thiab lub zog siab: qhov ceev sib piv yog ntawm 1.5 ~ 2.0, tsuas yog 1/4 ~ 1/5 ntawm cov hlau carbon, tab sis lub zog tensile yog ze rau lossis txawm tias ntau dua li cov hlau carbon, thiab lub zog tshwj xeeb tuaj yeem piv rau cov hlau alloy qib siab. Yog li ntawd, hauv kev tsav dav hlau, foob pob hluav taws, spacecraft, thawv siab, thiab lwm yam khoom uas xav tau txo qhov hnyav ntawm daim ntawv thov, muaj cov txiaj ntsig zoo heev. Lub zog tensile, flexural thiab compressive ntawm qee cov epoxy FRPs tuaj yeem ncav cuag ntau dua 400 MPa.

Kev tiv thaiv xeb zoo: GRP yog cov khoom siv tiv thaiv xeb zoo nrog kev tiv thaiv zoo rau huab cua, dej, thiab cov kua qaub, alkali, ntsev, nrog rau ntau yam roj thiab cov kuab tshuaj. Nws tau siv rau txhua yam ntawm kev tiv thaiv xeb tshuaj, thiab hloov cov hlau carbon, hlau tsis xeb, ntoo, cov hlau tsis yog ferrous thiab lwm yam.

Cov khoom siv hluav taws xob zoo: Nws yog qhov zoo heevcov khoom siv rwb thaiv tsev, siv los ua cov insulators. Zaus siab tseem tuaj yeem tiv thaiv cov khoom dielectric zoo. Microwave permeability zoo, tau siv dav hauv radomes.

Cov khoom zoo thermal: GRP thermal conductivity qis, chav sov li 1.25 ~ 1.67kJ / (mhK), tsuas yog 1/100 ~ 1/1000 ntawm cov hlau, yog cov khoom siv rwb thaiv tsev zoo heev. Thaum muaj qhov kub thiab txias siab heev, nws yog cov khoom siv tiv thaiv thermal thiab ablation zoo tshaj plaws, uas tuaj yeem tiv thaiv lub dav hlau hauv 2000 ℃ lossis ntau dua kom tiv taus cov cua ceev ceev.

Kev tsim qauv zoo:

① Txhua yam khoom siv tuaj yeem tsim tau yooj yim raws li qhov xav tau kom ua tau raws li qhov yuav tsum tau siv, uas tuaj yeem ua rau cov khoom muaj kev ncaj ncees zoo.

② tuaj yeem xaiv cov khoom siv kom ua tau raws li kev ua tau zoo ntawm cov khoom, xws li: tuaj yeem tsim cov khoom siv tiv taus corrosion, kub siab, cov khoom muaj lub zog siab, cov khoom siv dielectric zoo, thiab lwm yam.

Kev ua haujlwm zoo heev:

① Raws li cov duab ntawm cov khoom, cov kev cai lij choj, kev siv thiab tus lej ntawm kev xaiv yooj ywm ntawm cov txheej txheem molding.

② cov txheej txheem yooj yim, tuaj yeem ua pwm ib zaug, cov txiaj ntsig kev lag luam zoo heev, tshwj xeeb tshaj yog rau cov duab nyuaj, tsis yooj yim los tsim cov khoom me me, ntau dua hauv nws cov txheej txheem zoo dua.
