Tekinoroji yekusimbisa ngura yeFiberglass Sleeve pasi pemvura

Chifukidziro chegirazi chefaibhaTekinoroji yekusimbisa ngura pasi pemvura inobatanidza tekinoroji yemuno neyekunze uye yakabatana nemamiriro emunyika yeChina, uye kutanga kwehunyanzvi hwekuvaka tekinoroji yekusimbisa ngura yehydraulic concrete.

Tekinoroji iyi ine zvinhu zvakakosha zvinotevera:

1. inogona kuramba kutenderera kwemamiriro ekunze kunokonzerwa nekuoma nekunyorova, kupisa nekutonhora, kuonda nekunyunguduka nedzimwe nzira dzekushanda, uye mafungu emvura, mafungu egungwa, mvura yakasviba, maelectrolyte nezvimwe zvinokanganisa zvinogara zvichiitika kana kuti zvinogara zvichiitika, kugara kwenguva refu kwakanaka kwazvo.

2. Nekuda kwekusasimba kwe fiberglass sleeve kune makemikari, inogona kuramba mhando dzese dzemakemikari, uye inodzivirira zvakanyanya acid ne alkali, saka inogona kubata nengura yemvura yegungwa.

3. Nekuti hainyanyi kubatwa nemvura, ichiri nesimba rakasimba uye rakamanikana rekubatanidza (simba rekubatanidza rinosvika 2.5MPa) mukuvaka pasi pemvura. Kunyanya mu "kuvaka pasi pemvura", pasina chikonzero chekuvaka macofferdams nemidziyo yekudhonza mvura inodhura, igadziriro yakanakisa yekudzivirira ngura inochengetedza nguva, inochengetedza vashandi, uye inochengetedza mari.

4. Grout yemvura inodzivirira kupararira uye epoxy grout inogona kupinda mumakomba e substrate, zvichiita chimiro che rivet, kugadzirisa zviri nani uye kusimbisa chimiro chepakutanga.

Chifukidziro cheGirazi cheFiber Chakakosha:

ZvakakoshaGirazi Fiber Sleevechinhu chitsva chinoshanda chakagadzirwa neresin yakagadzirwa negirazi nefiber yegirazi kuburikidza nemaitiro ekubatanidza. Ipurasitiki inogadziriswa nethermosetting ine hunhu hunotevera:

Huremu hwakareruka uye simba guru: huwandu hwesimbi iri pakati pe1.5~2.0, 1/4~1/5 chete yesimbi yekabhoni, asi simba resimbi yekabhoni riri pedyo kana kutopfuura iro resimbi yekabhoni, uye simba racho rinogona kuenzaniswa nesimbi yemhando yepamusoro. Saka, mundege, maroketi, zvitundumuseremusere, midziyo ine simba guru, uye mune zvimwe zvigadzirwa zvinoda kuderedza huremu hwekushandisa, zvine mhedzisiro yakanaka. Simba resimbi yekabhoni, yeflexural uye yepressure yemamwe ma epoxy FRPs rinogona kusvika pamusoro pe400 MPa.

Kudzivirira ngura zvakanaka: GRP chinhu chakanaka chinodzivirira ngura chine simba rakanaka rekudzivisa mhepo, mvura, uye huwandu hwakawanda hwemaacid, alkalis, munyu, pamwe nemafuta akasiyana-siyana uye zvinonyungudutsa. Yakashandiswa kune zvese zvine chekuita nemakemikari anodzivirira ngura, uye iri kutsiva simbi yekabhoni, simbi isingatsvedzi, matanda, simbi dzisina feri nezvimwewo.

Hunhu hwakanaka hwemagetsi: Ibasa rakanaka kwazvozvinhu zvinodzivirira, inoshandiswa kugadzira zvinodzivirira kupisa. Kushandiswa kwemagetsi akawanda kunogona kuchengetedza hunhu hwakanaka hwe dielectric. Kupinda kwe microwave kwakanaka, kwave kuchishandiswa zvakanyanya muma radomes.

Hunhu hwakanaka hwekupisa: GRP ine thermal conductivity yakaderera, tembiricha yemukamuri ye1.25 ~ 1.67kJ / (mhK), 1/100 ~ 1/1000 chete yesimbi, chinhu chakanaka kwazvo chekudzivirira kupisa. Kana iri tembiricha yekukurumidza, ndiyo inodzivirira kupisa uye inodzivirira ablation, iyo inogona kuchengetedza spacecraft mu2000 ℃ kana kupfuura kuti ikwanise kutsungirira mhepo inomhanya nekukurumidza.

Kugadzirwa kwakanaka:

① Mhando dzese dzezvigadzirwa zvekuvaka dzinogona kugadzirwa zvinoenderana nezvinodiwa kuti zvienderane nezvinodiwa zvekushandisa, izvo zvinogona kuita kuti zvigadzirwa zvive zvakanaka.

2. Inogona kusarudza zvizere zvinhu kuti zvienderane nekushanda kwechigadzirwa, zvakaita se: inogona kugadzira chinhu chinodzivirira ngura, chinodzivirira kupisa kwakanyanya, chigadzirwa chine divi rayo rakasimba, hunhu hwakanaka hwe dielectric, nezvimwewo.

Unyanzvi hwakanaka kwazvo:

① Zvichienderana nechimiro chechigadzirwa, zvinodiwa zvehunyanzvi, mashandisirwo azvo uye huwandu hwesarudzo inochinjika yekuumba.

2. Maitiro acho ari nyore, anogona kuumbwa kamwe chete, mhedzisiro yehupfumi inoshamisa, kunyanya kune maumbirwo akaomarara, hazvisi nyore kuumba huwandu hushoma hwezvigadzirwa, zvinonyanya kuzivikanwa muhukuru hwemaitiro acho.
