I-Fiberglass Sleeve ye-Fiberglass ye-Sleeve ye-Underwater Corrosion Reinforcement Technology

Umkhono wefiber yeglasiItekhnoloji yokuqinisa i-anticorrosion engaphantsi kwamanzi yinkqubo yetekhnoloji enxulumene nasekhaya neyangaphandle kwaye idityaniswe neemeko zelizwe laseTshayina, kunye nokuqaliswa kwentsimi yolwakhiwo lwetekhnoloji yolwakhiwo lwe-concrete ye-hydraulic anticorrosion.

Itekhnoloji inezi mpawu zilandelayo ezibalulekileyo:

1. unokuxhathisa umjikelezo wemozulu obangelwa nguwomileyo kwaye umanzi, ushushu kwaye ubanda, ukukhenkceza kunye nokunyibilika kunye nokunye ukusebenzisana, kunye nemisinga yamanzi, amaza olwandle, amanzi amdaka, i-electrolytes kunye nezinye imiphumo eqhubekayo okanye ephazamisayo ephazamisayo, ukuqina kuhle kakhulu.

2. Ngenxa ye-inertia ye-fiberglass sleeve kwi-chemical reaction, iyakwazi ukuxhathisa zonke iintlobo zeekhemikhali, kwaye inamandla okumelana ne-asidi kunye ne-alkali, ngoko iyakwazi ukujamelana nokubola kwamanzi olwandle.

3. Ngenxa yokuba ayikhathali emanzini, isenamandla amakhulu kunye ne-tight bonding force (amandla okudibanisa ukuya kuthi ga kwi-2.5MPa) kulwakhiwo lwangaphantsi kwamanzi. Ngokukodwa "kwisakhiwo sangaphantsi kwamanzi", ngaphandle kwesidingo sokwakha i-cofferdams kunye nezixhobo zokukhupha amanzi ezibizayo, isethi yokugcina ixesha, ukugcinwa kwabasebenzi, ukonga imali eyona ndlela yokulwa nokubola.

4. I-grout ye-anti-dispersion yangaphantsi kwamanzi kunye ne-epoxy grout inokungena kwiintanda ze-substrate, zenze isakhiwo se-rivet, ukulungiswa okungcono kunye nokuqiniswa kwesakhiwo sokuqala.

Umkhono weFayibha weGlasi oKhethekileyo:

EkhethekileyoUmkhono weFayibha yeglasisisixhobo esitsha esisebenzayo esenziwe ngeresin eyenziweyo kunye nefiber yeglasi ngenkqubo edibeneyo. Yimathiriyeli ye-thermosetting yepolymer eneempawu ezilandelayo:

Ubunzima bokukhanya kunye namandla aphezulu: ukuxinana okuhambelanayo kuphakathi kwe-1.5 ~ 2.0, kuphela i-1/4 ~ 1/5 yensimbi ye-carbon, kodwa amandla okuqina asondele okanye adlule kwi-carbon steel, kwaye amandla athile anokuthelekiswa nalawo ensimbi ye-alloy ye-high-grade. Ke ngoko, kwinqwelomoya, iirokethi, iziphekepheke, izikhongozeli zoxinzelelo oluphezulu, nakwezinye iimveliso ezifuna ukunciphisa ubunzima besicelo, zineziphumo ezigqwesileyo. Ukuqina, ukuguquguquka kunye namandla oxinzelelo kwezinye ii-epoxy FRPs zinokufikelela ngaphezulu kwe-400 MPa.

Ukumelana ne-corrosion elungileyo: I-GRP sisixhobo esihle esinganyangekiyo ku-corrosion kunye nokumelana kakuhle ne-atmosfera, amanzi, kunye nokugxilwa ngokubanzi kwee-asidi, iialkali, iityuwa, kunye neentlobo ngeentlobo zee-oyile kunye nezinyibilikisi. Isetyenziswe kuzo zonke iinkalo zemichiza echasene ne-corrosion, kwaye ithatha indawo ye-carbon steel, insimbi engenasici, i-wood, i-non-ferrous metals kunye nokunye.

Iimpawu zombane ezilungileyo:Yeyona nto ibalaseleyoizinto zokugquma, esetyenziselwa ukwenza izithinteli. I-Frequency ephezulu isenokuthi ikhusele iipropathi ezilungileyo ze-dielectric. I-Microwave permeability ilungile, isetyenziswe ngokubanzi kwiiradomes.

Iimpawu ezilungileyo ze-thermal: i-GRP ephantsi kwe-thermal conductivity, ubushushu begumbi le-1.25 ~ 1.67kJ / (mhK), kuphela i-1/100 ~ 1/1000 yentsimbi, yinto egqwesileyo yokufakelwa kwe-thermal. Kwimeko yobushushu obudlulayo obuphezulu, lolona khuselo lufanelekileyo lobushushu kunye nezixhobo ezikwaziyo ukunqanda ukuphuma, ezinokukhusela isiphekepheke ngo-2000 ℃ okanye ngaphezulu ukumelana nokuhamba komoya okuhamba ngesantya esiphezulu.

Ukuyilwa kakuhle:

① Zonke iintlobo zeemveliso zolwakhiwo zinokuyilwa ngokuguquguqukayo ngokweemfuno zokuhlangabezana neemfuno zokusetyenziswa, ezinokwenza imveliso ibe nemfezeko elungileyo.

② unokukhetha ngokupheleleyo umbandela wokuhlangabezana nokusebenza kwemveliso, njengale: inokuyila i-corrosion-resistant, ukumelana nobushushu obuphezulu, imveliso inesalathiso esithile samandla aphezulu, iipropathi ezilungileyo ze-dielectric, njalo njalo.

Ubugcisa obugqwesileyo:

① Ngokwemilo yemveliso, iimfuno zobugcisa, ukusetyenziswa kunye nenani lokukhetha okuguquguqukayo kwenkqubo yokubumba.

② inkqubo ilula, inokubunjwa kanye, umphumo wezoqoqosho ubalaseleyo, ngakumbi kwiimilo ezintsonkothileyo, akukho lula ukwenza inani elincinci leemveliso, ezivelele ngakumbi kwinkqubo yokuphakama kwayo.
