Ukadaulo Wolimbitsa Dzimbiri wa Fiberglass Sleeve Underwater

Chikwama cha ulusi wagalasiUkadaulo wolimbitsa mphamvu zoteteza dzimbiri pansi pa madzi ndi kapangidwe ka ukadaulo wokhudzana ndi dziko la China komanso wakunja, komanso kuyambitsa ukadaulo wolimbitsa mphamvu zoteteza dzimbiri pogwiritsa ntchito konkriti ya hydraulic.

Ukadaulowu uli ndi zinthu zofunika izi:

1. imatha kukana kusintha kwa nyengo komwe kumachitika chifukwa cha kuuma ndi kunyowa, kutentha ndi kuzizira, kuzizira ndi kusungunuka ndi zina, komanso mafunde amadzi, mafunde a m'nyanja, madzi otayira, ma electrolyte ndi zina zomwe zimawononga nthawi zonse kapena nthawi zina, kulimba kwake ndikwabwino kwambiri.

2. Chifukwa cha kufooka kwa chigoba cha fiberglass ku zotsatira za mankhwala, chimatha kukana mitundu yonse ya mankhwala, ndipo chimalimbana kwambiri ndi asidi ndi alkali, kotero chimatha kuthana ndi dzimbiri la madzi a m'nyanja.

3. Popeza sichimakhudzidwa ndi madzi, chimakhala ndi mphamvu yolimba komanso yolimba yolumikizirana (mphamvu yolumikizirana mpaka 2.5MPa) pomanga pansi pa madzi. Makamaka mu "kumanga pansi pa madzi", popanda kufunika komanga ma cofferdams ndi zida zokwera mtengo zotulutsira madzi, ndi njira yabwino kwambiri yotetezera dzimbiri, yopulumutsa nthawi, komanso yopulumutsa ndalama.

4. Grout yoletsa kufalikira kwa madzi ndi grout ya epoxy imatha kulowa m'ming'alu ya substrate, ndikupanga kapangidwe ka rivet, kukonza bwino ndikulimbitsa kapangidwe koyambirira.

Chikwama Chapadera cha Ulusi wa Galasi:

ZapaderaChikwama cha Ulusi wa Galasindi chinthu chatsopano chogwira ntchito chopangidwa ndi utomoni wopangidwa ndi ulusi wagalasi pogwiritsa ntchito njira yophatikizika. Ndi chinthu cha polima chotenthetsera kutentha chokhala ndi makhalidwe otsatirawa:

Kulemera kopepuka ndi mphamvu yayikulu: kuchuluka kwa mphamvu kuli pakati pa 1.5 ~ 2.0, 1/4 ~ 1/5 yokha ya chitsulo cha kaboni, koma mphamvu yokoka ili pafupi kapena kupitirira ya chitsulo cha kaboni, ndipo mphamvu yeniyeniyo ingayerekezeredwe ndi ya chitsulo cha alloy chapamwamba. Chifukwa chake, mu ndege, maroketi, zombo zamlengalenga, zotengera zamagetsi amphamvu, ndi zinthu zina zomwe zimafunika kuchepetsa kulemera kwa ntchito, zimakhala ndi zotsatira zabwino kwambiri. Mphamvu yokoka, yopindika komanso yopondereza ya ma epoxy FRP ena imatha kufika pa 400 MPa.

Kukana dzimbiri: GRP ndi chinthu chabwino chokana dzimbiri chomwe chimakana mlengalenga, madzi, ndi kuchuluka kwa ma asidi, alkali, mchere, komanso mafuta osiyanasiyana ndi zosungunulira. Chagwiritsidwa ntchito pazinthu zonse zokhudzana ndi mankhwala oletsa dzimbiri, ndipo chikulowa m'malo mwa chitsulo cha kaboni, chitsulo chosapanga dzimbiri, matabwa, zitsulo zopanda chitsulo ndi zina zotero.

Katundu wabwino wamagetsi: Ndi wabwino kwambirizinthu zotetezera kutentha, imagwiritsidwa ntchito popanga zotetezera kutentha. Ma frequency apamwamba amatha kutetezabe mphamvu zabwino za dielectric. Kulowa kwa microwave ndikwabwino, ndipo kwagwiritsidwa ntchito kwambiri mu radomes.

Makhalidwe abwino a kutentha: GRP yotsika kutentha, kutentha kwa chipinda kwa 1.25 ~ 1.67kJ / (mhK), 1/100 ~ 1/1000 yokha ya chitsulocho, ndi chinthu chabwino kwambiri chotetezera kutentha. Pankhani ya kutentha kwachangu kwambiri, ndi chitetezo chabwino kwambiri cha kutentha komanso zinthu zosagwira ntchito, zomwe zimatha kuteteza chombocho mu 2000 ℃ kapena kuposerapo kuti chipirire mpweya wothamanga kwambiri.

Kupanga bwino:

① Mitundu yonse ya zinthu zopangidwa ndi kapangidwe kake imatha kupangidwa mosinthasintha malinga ndi zosowa zake kuti ikwaniritse zofunikira pakugwiritsa ntchito, zomwe zingapangitse kuti zinthuzo zikhale ndi umphumphu wabwino.

2. Akhoza kusankha bwino zinthu zomwe zikugwirizana ndi ntchito ya chinthucho, monga: akhoza kupanga chinthu cholimba komanso cholimba, chomwe chimateteza kutentha kwambiri, chomwe chili ndi mphamvu zambiri, mphamvu zabwino za dielectric, ndi zina zotero.

Luso labwino kwambiri:

① Malinga ndi mawonekedwe a chinthucho, zofunikira zaukadaulo, kagwiritsidwe ntchito ndi kuchuluka kwa njira zosinthira zoumba.

2. Njira ndi yosavuta, ikhoza kupangidwa kamodzi, zotsatira zake zachuma zimakhala zabwino kwambiri, makamaka pa mawonekedwe ovuta, sizili zosavuta kupanga zinthu zochepa, zomwe zimaonekera kwambiri mu njira yake yopambana.
