Itekhnoloji yokuqinisa ukugqwala phantsi kwamanzi kwi-fiberglass Sleeve

Isingxobo sefayibha yeglasiItekhnoloji yokuqinisa ulwelo phantsi kwamanzi kukuhlanganiswa kwetekhnoloji enxulumene nekhaya nelangaphandle kwaye idityaniswe neemeko zelizwe laseTshayina, kunye nokuqaliswa kwecandelo letekhnoloji yokwakha ulwelo lokuqinisa ulwelo lwekhonkrithi ye-hydraulic.

Le teknoloji ineempawu ezibalulekileyo ezilandelayo:

1. inokumelana nomjikelo wemozulu obangelwa kukuma okomileyo nokumanzi, ubushushu nokubanda, ukubanda nokunyibilika kunye nezinye iindlela zokunxibelelana, kunye nemisinga yamanzi, amaza olwandle, amanzi amdaka, ii-electrolytes kunye nezinye iziphumo zokubola eziqhubekayo okanye ezingapheliyo, ukuqina kwayo kulungile.

2. Ngenxa yokungabi namandla kwesingxobo se-fiberglass kwi-chemical reaction, inokumelana nazo zonke iintlobo zeekhemikhali, kwaye inokumelana kakhulu ne-asidi kunye ne-alkali, ngoko ke inokumelana nokugqwala kwamanzi olwandle.

3. Ngenxa yokuba ayinangxaki emanzini, isenamandla okubopha aqinileyo kakhulu (amandla okubopha afikelela kwi-2.5MPa) kulwakhiwo olungaphantsi kwamanzi. Ingakumbi "kulwakhiwo olungaphantsi kwamanzi", ngaphandle kwesidingo sokwakha ii-cofferdams kunye nezixhobo zokuhambisa amanzi ezibizayo, iseti yenkqubo yokulwa nokugqwala egcina ixesha, egcina abasebenzi, negcina imali.

4. I-grout engaphantsi kwamanzi echasene nokusasazeka kunye ne-epoxy grout zinokungena kwiimfanta ze-substrate, zenze isakhiwo se-rivet, ukulungiswa okungcono kunye nokuqinisa isakhiwo sokuqala.

Isingxobo seFayibha yeGlasi esiKhethekileyo:

ekhethekileyoIsingxobo seFayibha yeGlasisisixhobo esitsha esisebenzayo esenziwe nge-synthetic resin kunye ne-glass fiber ngenkqubo ye-composite. Sisixhobo se-thermosetting polymer esineempawu ezilandelayo:

Ubunzima obulula kunye namandla aphezulu: uxinano oluhambelanayo luphakathi kwe-1.5 ~ 2.0, yi-1/4 ~ 1/5 kuphela yentsimbi yekhabhoni, kodwa amandla okutsalwa asondele okanye adlule kwawentsimbi yekhabhoni, kwaye amandla athile anokuthelekiswa nalawo entsimbi ye-alloy yodidi oluphezulu. Ke ngoko, kwiinqwelomoya, iirokethi, iinqanawa zasemoyeni, izikhongozeli zoxinzelelo oluphezulu, nakwezinye iimveliso ezifuna ukunciphisa ubunzima besicelo, zineziphumo ezigqwesileyo. Amandla okutsalwa, okugobeka kunye nokucinezelwa kwezinye ii-epoxy FRPs anokufikelela ngaphezulu kwe-400 MPa.

Ukumelana kakuhle nokugqwala: I-GRP yinto efanelekileyo ekwaziyo ukumelana nokugqwala enokumelana kakuhle nomoya, amanzi, kunye noxinzelelo oluqhelekileyo lwee-asidi, ii-alkali, iityuwa, kunye neendidi ezahlukeneyo zeeoyile kunye nezinyibilikisi. Isetyenziswe kuzo zonke iinkalo zekhemikhali yokulwa nokugqwala, kwaye ithatha indawo yentsimbi yekhabhoni, intsimbi engatyiwayo, umthi, iintsimbi ezingezizo iintsimbi njalo njalo.

Iipropati ezilungileyo zombane: Yinto entle kakhuluizinto zokukhusela ubushushu, isetyenziselwa ukwenza ii-insulator. Isantya esiphezulu sisenokukhusela iipropati ezilungileyo ze-dielectric. Ukungena kwe-microwave kulungile, kwaye kusetyenziswe kakhulu kwii-radomes.

Iipropati ezilungileyo zobushushu: Ukuqhuba kobushushu obuphantsi kwe-GRP, ubushushu begumbi obuyi-1.25 ~ 1.67kJ / (mhK), yi-1/100 ~ 1/1000 kuphela yesinyithi, sisixhobo esihle kakhulu sokukhusela ubushushu. Kwimeko yobushushu obuphantsi kakhulu, sisixhobo esifanelekileyo sokukhusela ubushushu kunye nezixhobo ezimelana nokukhupha umoya, esinokukhusela inqwelo-moya kwi-2000 ℃ nangaphezulu ukuze imelane nokuhamba komoya okukhawulezayo.

Uyilo oluhle:

① Zonke iintlobo zeemveliso zesakhiwo zinokuyilwa ngokuguquguqukayo ngokweemfuno ukuze kuhlangatyezwane neemfuno zokusetyenziswa, nto leyo enokwenza iimveliso zibe nomgangatho olungileyo.

2. Ungakhetha ngokupheleleyo izinto ezifunekayo ukuze zihambelane nokusebenza kwemveliso, ezinje: unokuyila isixhobo esimelana nokugqwala, esinokumelana nobushushu obuphezulu, imveliso inamandla aphezulu kwicala elithile, ineempawu ezilungileyo ze-dielectric, njl.

Ubuchule obugqwesileyo:

① Ngokwemilo yemveliso, iimfuno zobugcisa, ukusetyenziswa kwayo kunye nenani leenkqubo zokubumba eziguquguqukayo.

② inkqubo ilula, inokubunjwa kube kanye, isiphumo sezoqoqosho sibalasele, ingakumbi kwiimilo ezintsonkothileyo, akukho lula ukwenza inani elincinci leemveliso, kwaye ibaluleke ngakumbi kwinkqubo yayo.
