Fiberglass Sleeve Underwater Corrosion Reinforcement Technology

Chingwe chagalasi cha fiberpansi pamadzi anticorrosion kulimbikitsa luso ndi kaphatikizidwe wa luso zoweta ndi akunja okhudzana ndi kuphatikizidwa ndi zinthu dziko China, ndi kukhazikitsidwa kwa munda wa hayidiroliki konkire anticorrosion kulimbitsa luso luso.

Tekinolojeyi ili ndi zinthu zotsatirazi:

1. imatha kukana kusinthasintha kwanyengo chifukwa chowuma ndi kunyowa, kutentha ndi kuzizira, kuzizira ndi kusungunuka ndi kuyanjana kwina, ndi mafunde amadzi, mafunde a m'nyanja, madzi onyansa, ma electrolyte ndi zina zopitirira kapena zowonongeka zowonongeka, kukhazikika ndikwabwino kwambiri.

2. Chifukwa cha inertia ya manja a fiberglass ku mphamvu ya mankhwala, imatha kukana mitundu yonse ya mankhwala, ndipo imakhala ndi mphamvu yolimbana ndi asidi ndi alkali, kotero imatha kulimbana ndi kuwonongeka kwa madzi a m'nyanja.

3. Chifukwa sichikhudzidwa ndi madzi, chimakhalabe ndi mphamvu zomangirira zamphamvu kwambiri (mphamvu zomangirira mpaka 2.5MPa) pomanga pansi pa madzi. Makamaka mu "kumanga pansi pa madzi", popanda kufunikira komanga ma cofferdams ndi zida zotayira zamtengo wapatali, ndi ndondomeko yosungira nthawi, yopulumutsa ntchito, yopulumutsa ndalama yabwino kwambiri yolimbana ndi dzimbiri.

4. pansi pa madzi odana ndi kumwazikana grout ndi epoxy grout akhoza kulowa mu ming'alu ya gawo lapansi, kupanga rivet dongosolo, kukonzanso bwino ndi kulimbikitsa mapangidwe oyambirira.

Sleeve Wapadera wa Glass Fiber:

WapaderaGlass Fiber Sleevendi chinthu chatsopano chopangidwa ndi utomoni wopangidwa ndi magalasi ndi utomoni wagalasi pogwiritsa ntchito kompositi. Ndi thermosetting polima zakuthupi ndi makhalidwe awa:

Kulemera kopepuka ndi mphamvu yayikulu: kachulukidwe kachibale ndi pakati pa 1.5 ~ 2.0, 1/4 ~ 1/5 yokha ya chitsulo cha kaboni, koma mphamvu yamakokedwe imakhala pafupi kapena kuposa ya chitsulo cha kaboni, ndipo mphamvu yeniyeniyo imatha kufananizidwa ndi chitsulo chapamwamba kwambiri. Chifukwa chake, mu ndege, maroketi, mlengalenga, zotengera zothamanga kwambiri, ndi zinthu zina zomwe zimafunikira kuchepetsa kulemera kwa pulogalamuyi, zimakhala ndi zotsatira zabwino kwambiri. Kulimba, kusinthasintha komanso kukakamiza kwa ma FRP ena a epoxy amatha kufikira 400 MPa.

Kukana kwa dzimbiri kwabwino: GRP ndi chinthu chabwino chosachita dzimbiri chomwe chimalimbana bwino ndi mpweya, madzi, komanso kuchuluka kwa zidulo, ma alkali, mchere, komanso mafuta osiyanasiyana ndi zosungunulira. Zakhala zikugwiritsidwa ntchito pazinthu zonse za mankhwala odana ndi dzimbiri, ndikulowetsa mpweya wa carbon, zitsulo zosapanga dzimbiri, matabwa, zitsulo zopanda chitsulo ndi zina zotero.

Zabwino zamagetsi: Ndi zabwino kwambirizipangizo zotetezera, zomwe zimagwiritsidwa ntchito kupanga zotetezera. Ma frequency apamwamba amathabe kuteteza zinthu zabwino za dielectric. Microwave permeability ndi yabwino, yakhala ikugwiritsidwa ntchito kwambiri mu radomes.

Kutentha kwabwino: GRP low thermal conductivity, kutentha kwa chipinda kwa 1.25 ~ 1.67kJ / (mhK), 1/100 ~ 1/1000 yokha yachitsulo, ndi chinthu chabwino kwambiri chotetezera kutentha. Pankhani ya kutentha kwapang'onopang'ono kwambiri, ndiye chitetezo choyenera chamafuta komanso zinthu zosagwira ntchito, zomwe zimatha kuteteza chombocho mu 2000 ℃ kapena kupitilira apo kuti zisapirire kuthamanga kwa mpweya.

Kupanga bwino:

① Mitundu yonse yazinthu zamapangidwe zimatha kupangidwa mosinthika malinga ndi zofunikira kuti zikwaniritse zofunikira zogwiritsidwa ntchito, zomwe zingapangitse kuti zinthuzo zikhale ndi kukhulupirika.

② imatha kusankha zinthu zonse kuti zigwirizane ndi momwe zinthu zikugwiritsidwira ntchito, monga: zimatha kupanga zosagwirizana ndi dzimbiri, kukana kutentha kwambiri, mankhwalawo amakhala ndi njira inayake yamphamvu kwambiri, katundu wabwino wa dielectric, ndi zina zotero.

Kuchita bwino kwambiri:

① Malinga ndi mawonekedwe a chinthucho, zofunikira zaukadaulo, kugwiritsa ntchito komanso kuchuluka kwa kusankha kosinthika pakuumba.

② ndondomeko ndi yosavuta, akhoza kuumbidwa kamodzi, zotsatira zachuma ndi zabwino kwambiri, makamaka akalumikidzidwa zovuta, n'kosavuta kupanga chiwerengero chochepa cha mankhwala, odziwika kwambiri mu ndondomeko apamwamba.
