Fiberglass Sleeve Underwater Corrosion Reinforcement Technology

Girazi fiber sleeveunderwater anticorrosion reinforcement tekinoroji inosanganisa tekinoroji yemukati neyekunze ine hukama uye yakasanganiswa nemamiriro emunyika yeChina, uye kutangwa kwemunda we hydraulic kongiri anticorrosion reinforcement yekuvaka tekinoroji.

Iyo tekinoroji ine zvinotevera zvakakosha maficha:

1. inogona kurwisa kutenderera kwemamiriro ekunze kunokonzerwa nekuoma uye kunyorova, kupisa uye kutonhora, kutonhora nekunyunguduka uye kumwe kupindirana, uye mafungu emvura, mafungu egungwa, mvura yakasviba, electrolytes nezvimwe zvinoramba zvichiitika kana zvinokanganisa zvinokonzera, kusimba kwakanakisisa.

2. Nemhaka yeinertia yefiberglass sleeve kune chemikemikari inogadzirisa, inogona kurwisana nemhando dzose dzemakemikari, uye ine simba rakasimba kune acid uye alkali, saka inogona kutarisana nekuora kwemvura yegungwa.

3. Nekuti hainzwisisi mvura, ichine simba rakasimba uye rakasimba rekubatana (simba rekubatanidza kusvika ku2.5MPa) mukuvaka pasi pemvura. Kunyanya mu "kuvakwa kwepasi pemvura", pasina kudiwa kwekuvaka cofferdams uye inodhura midziyo yemvura, igadziriro yekuchengetedza nguva, kuchengetedza kushanda, kuchengetedza mari zvakanakisisa anti-corrosion system.

4. pasi pemvura anti-dispersion grout uye epoxy grout inogona kupinda mukati mekuputika kwe substrate, ichiita rivet chimiro, kugadzirisa zviri nani uye kusimbiswa kwechimiro chepakutanga.

Special Glass Fiber Sleeve:

SpecialGirazi Fiber Sleevechinhu chitsva chinoshanda chakagadzirwa nesynthetic resin uye girazi faibha necomposite maitiro. Iyo thermosetting polymer zvinhu zvine zvinotevera maitiro:

Huremu huremu uye simba rakakwirira: hukama huri pakati pe 1.5 ~ 2.0, chete 1/4 ~ 1/5 ye carbon steel, asi simba rekusimba riri pedyo kana kutopfuura iro re carbon steel, uye iyo chaiyo simba inogona kuenzaniswa neiyo yepamusoro-giredhi alloy simbi. Naizvozvo, mundege, maroketi, spacecraft, midziyo yekudzvanya, uye mune zvimwe zvigadzirwa zvinoda kudzikisa huremu hwekushandisa, zvine mhedzisiro yakanaka. Kusimba, kuchinjika uye kumanikidza kwemamwe epoxy FRPs anogona kusvika pamusoro pe400 MPa.

Good corrosion resistance: GRP chinhu chakanaka chisingadziviriri uye chinopesana nemhepo, mvura, uye huwandu hwehuwandu hweasidhi, alkalis, munyu, pamwe nemafuta akasiyana-siyana uye zvinonyungudutsa. Iyo yakashandiswa kune ese maficha emakemikari anti-corrosion, uye iri kutsiva kabhoni simbi, simbi isina tsvina, huni, isina-ferrous simbi uye zvichingodaro.

Zvakanaka magetsi zvivakwa:Iyo yakanakainsulating zvinhu, yaishandiswa kugadzira insulators. Yakakwira frequency inogona kuchengetedza yakanaka dielectric zvivakwa. Microwave permeability yakanaka, yakashandiswa zvakanyanya mumaradomes.

Zvakanaka kupisa zvivakwa: GRP yakaderera thermal conductivity, tembiricha yekamuri ye1.25 ~ 1.67kJ / (mhK), chete 1/100 ~ 1/1000 yesimbi, yakanakisa yekupisa yekupisa zvinhu. Kana iri yenguva pfupi yekupedzisira-yepamusoro tembiricha, ndiyo yakanakira kuchengetedzwa kwemafuta uye ablation-resistant zvinhu, izvo zvinogona kuchengetedza spacecraft muna 2000 ℃ kana kupfuura kuti imire nekumhanya-mhanya kwemhepo.

Kugadzirwa kwakanaka:

① Mhando dzese dzezvigadzirwa zvezvimiro zvinogona kuchinjika kugadzirwa zvinoenderana nezvinodiwa kuzadzisa zvinodiwa zvekushandisa, izvo zvinogona kuita kuti zvigadzirwa zvive nekuvimbika kwakanaka.

② inogona kusarudza zvizere zvinhu kuti zvisangane nekushanda kwechigadzirwa, senge: inogona kugadzira inodzivirira corrosion, yakakwirira tembiricha kuramba, chigadzirwa chine imwe nzira yesimba rakakwirira, yakanaka dielectric zvivakwa, zvichingodaro.

Unyanzvi hwakanakisa:

① Zvinoenderana nechimiro chechigadzirwa, tekinoroji zvinodiwa, kushandiswa uye huwandu hwesarudzo inoshanduka yekuumba maitiro.

② maitiro ari nyore, anogona kuumbwa kamwe chete, maitiro ehupfumi anoshamisa, kunyanya kune akaomesesa maumbirwo, hazvisi nyore kuumba nhamba shoma yezvigadzirwa, zvakanyanya kusimba muhukuru hwayo.
