I-Fiberglass Sleeve Underwater Corrosion Reinforcement Technology

Umkhono we-fiber yengilaziUbuchwepheshe bokuqiniswa kwe-anticorrosion engaphansi kwamanzi buwukuhlanganiswa kobuchwepheshe obuhlobene basekhaya nabangaphandle futhi buhlanganiswe nezimo zezwe laseChina, kanye nokwethulwa komkhakha wobuchwepheshe bokwakhiwa kokuqinisa ukuqina kokhonkolo owenziwe nge-hydraulic anticorrosion.

Ubuchwepheshe bunezici ezilandelayo ezibalulekile:

1. ingamelana nomjikelezo wesimo sezulu obangelwa ukomile nokumanzi, ukushisa nokubanda, ukuqhwa nokuncibilika nokunye ukusebenzisana, nemisinga yamanzi, amagagasi olwandle, amanzi angcolile, ama-electrolyte neminye imiphumela egqwalayo eqhubekayo noma eqhubekayo, ukuqina kuhle kakhulu.

2. Ngenxa ye-inertia yomkhono we-fiberglass ekuphenduleni kwamakhemikhali, ingakwazi ukumelana nazo zonke izinhlobo zamakhemikhali, futhi inokumelana okuqinile ne-asidi ne-alkali, ngakho ingakwazi ukubhekana nokugqwala kwamanzi olwandle.

3. Ngenxa yokuthi ayizwani namanzi, isenamandla amakhulu futhi aqinile okuhlanganisa (amandla okubopha afika ku-2.5MPa) ekwakhiweni kwamanzi. Ikakhulukazi "ekwakhiweni kwamanzi ngaphansi kwamanzi", ngaphandle kwesidingo sokwakha ama-cofferdams kanye nemishini yokukhipha amanzi ebizayo, isethi yohlelo oluhle kakhulu lokulwa nokugqwala okonga isikhathi, ukonga umsebenzi, ukonga imali.

4. I-anti-dispersion grout engaphansi kwamanzi kanye ne-epoxy grout ingangena emifantwini ye-substrate, yakha isakhiwo se-rivet, ukulungiswa okungcono nokuqiniswa kwesakhiwo sokuqala.

Umkhono Okhethekile We-Glass Fiber:

OkukhethekileI-Glass Fiber Sleevekuyinto entsha esebenzayo eyenziwe nge-synthetic resin kanye ne-glass fiber ngenqubo eyinhlanganisela. Kuyinto ye-polymer ye-thermosetting enezici ezilandelayo:

Isisindo esilula namandla aphezulu: ukuminyana okuhlobene kuphakathi kuka-1.5~2.0, kuphela 1/4~1/5 wensimbi ye-carbon, kodwa amandla aqinile aseduze noma adlule ngisho nalawo ensimbi ye-carbon, futhi amandla athile angafaniswa nalawo ensimbi ye-alloy yezinga eliphezulu. Ngakho-ke, ezindizeni, amarokhethi, imikhumbi-mkhathi, iziqukathi ezinengcindezi ephezulu, nakweminye imikhiqizo edinga ukunciphisa isisindo sohlelo lokusebenza, ibe nemiphumela emihle kakhulu. Amandla aqinile, aguquguqukayo futhi acindezelayo amanye ama-epoxy FRPs angafinyelela ngaphezu kuka-400 MPa.

Ukumelana nokugqwala okuhle: I-GRP iyinto enhle ekwazi ukumelana nokugqwala futhi imelana kahle nomoya osemkhathini, emanzini, kanye nokugcwala okujwayelekile kwama-asidi, ama-alkali, usawoti, kanye nezinhlobonhlobo zamafutha nezinyibilikisi. Isetshenziswe kuzo zonke izici zamakhemikhali e-anti-corrosion, futhi ithatha indawo ye-carbon steel, insimbi engagqwali, izinkuni, izinsimbi ezingenayo insimbi nokunye.

Izakhiwo zikagesi ezinhle: Yinhle kakhului-insulating material, esetshenziselwa ukwenza ama-insulators. Imvamisa ephezulu isengakwazi ukuvikela izici ezinhle ze-dielectric. I-Microwave permeability yinhle, isetshenziswe kakhulu kuma-radomes.

Izakhiwo ezinhle zokushisa: I-GRP ephansi ye-thermal conductivity, izinga lokushisa legumbi lika-1.25 ~ 1.67kJ / (mhK), kuphela i-1/100 ~ 1/1000 yensimbi, iyinto enhle kakhulu yokufakwa kwe-thermal. Esimeni sokushisa kwesikhashana okuphezulu kakhulu, iwukuvikela okushisayo okufanelekile nezinto ezimelana nokukhipha umoya, ezingavikela umkhumbi-mkhathi ngo-2000 ℃ noma ngaphezulu ukuze umelane nokugeleza komoya okunesivinini esikhulu.

Ukuklama okuhle:

① Zonke izinhlobo zemikhiqizo yesakhiwo zingaklanywa ngendlela eguquguqukayo ngokuya ngezidingo ukuhlangabezana nezidingo zokusetshenziswa, ezingenza imikhiqizo ibe nobuqotho obuhle.

② ingakhetha ngokugcwele okokusebenza ukuze kuhlangatshezwane nokusebenza komkhiqizo, njengokuthi: ingakwazi ukuklama ukumelana nokugqwala, ukumelana nokushisa okuphezulu, umkhiqizo unesiqondiso esithile samandla aphezulu, izakhiwo ezinhle ze-dielectric, njalonjalo.

Ubuciko obuhle kakhulu:

① Ngokusho komumo womkhiqizo, izidingo zobuchwepheshe, ukusetshenziswa kanye nenani lokukhetha okuguquguqukayo kwenqubo yokubumba.

② inqubo ilula, ingabunjwa kanye, umphumela wezomnotho uvelele, ikakhulukazi izimo eziyinkimbinkimbi, akulula ukwakha inombolo encane yemikhiqizo, evelele kakhulu ekuphakameni kwayo.
