Ubuchwepheshe Bokuqinisa Ukugqwala Ngaphansi Kwamanzi Ngesiketi Se-Fiberglass Sleeve

Isikhafu sefayibha yengilaziUbuchwepheshe bokuqinisa ukulwa nokugqwala ngaphansi kwamanzi buwukuhlanganiswa kobuchwepheshe obuhlobene nekhaya nakwamanye amazwe futhi buhlanganiswe nezimo zezwe laseShayina, kanye nokuqaliswa kwensimu yobuchwepheshe bokwakha ukuqinisa ukhonkolo we-hydraulic anticorrosion.

Ubuchwepheshe bunezici ezilandelayo ezibalulekile:

1. ingamelana nomjikelezo wesimo sezulu obangelwa ukoma nokumanzi, ukushisa nokubanda, ukubanda nokuncibilika kanye nokunye ukusebenzisana, kanye nemisinga yamanzi, amaza olwandle, amanzi angcolile, ama-electrolyte kanye neminye imiphumela yokugqwala eqhubekayo noma eyenzeka ngezikhathi ezithile, ukuqina kuhle kakhulu.

2. Ngenxa yokungabi namandla kwesivikelo se-fiberglass ekusabeleni kwamakhemikhali, ingamelana nazo zonke izinhlobo zama-chemical agents, futhi inokumelana okunamandla ne-asidi ne-alkali, ngakho-ke ingabhekana nokugqwala kwamanzi olwandle.

3. Ngenxa yokuthi ayizweli emanzini, isenamandla okubopha aqinile kakhulu (amandla okubopha afinyelela ku-2.5MPa) ekwakhiweni kwamanzi. Ikakhulukazi "ekwakhiweni kwamanzi", ngaphandle kwesidingo sokwakha ama-cofferdams kanye nemishini yokudonsa ebizayo, iyisethi yesistimu yokulwa nokugqwala esonga isikhathi, esonga abasebenzi, nesonga imali.

4. i-grout elwa nokuhlakazeka ngaphansi kwamanzi kanye ne-epoxy grout kungangena emifantwini ye-substrate, kwakha isakhiwo se-rivet, ukulungiswa okungcono kanye nokuqinisa isakhiwo sokuqala.

Isikhindi Se-Glass Fiber Esikhethekile:

OkukhethekileIsikhwama se-Glass Fiberiyinto entsha esebenzayo eyenziwe nge-resin yokwenziwa kanye nefayibha yengilazi ngenqubo ehlanganisiwe. Iyinto ye-polymer ye-thermosetting enezici ezilandelayo:

Isisindo esilula kanye namandla aphezulu: ubuningi obuhlobene buphakathi kuka-1.5 ~ 2.0, yi-1/4 ~ 1/5 kuphela yensimbi yekhabhoni, kodwa amandla okudonsa aseduze noma adlula ngisho nalawo ensimbi yekhabhoni, futhi amandla athile angafaniswa nalawo ensimbi ye-alloy yezinga eliphezulu. Ngakho-ke, ezindizeni, amarokhethi, izindiza-mkhathi, izitsha ezinomfutho ophezulu, kanye neminye imikhiqizo edinga ukunciphisa isisindo sohlelo lokusebenza, inemiphumela emihle kakhulu. Amandla okudonsa, okuguquguquka kanye nokucindezela kwamanye ama-epoxy FRP angafinyelela ngaphezu kuka-400 MPa.

Ukumelana okuhle nokugqwala: I-GRP iyinto enhle engagqwali enokumelana okuhle nomoya, amanzi, kanye nokugcwala okujwayelekile kwama-asidi, ama-alkali, usawoti, kanye namafutha ahlukahlukene kanye nezinyibilikisi. Isetshenziswe kuzo zonke izici zokulwa nokugqwala ngamakhemikhali, futhi ithatha indawo yensimbi yekhabhoni, insimbi engagqwali, ukhuni, izinsimbi ezingezona i-ferrous njalo njalo.

Izakhiwo zikagesi ezinhle: Kuhle kakhuluizinto zokuvikela umswakama, esetshenziselwa ukwenza ama-insulator. Imvamisa ephezulu isengavikela izakhiwo ezinhle ze-dielectric. Ukuvuleka kwe-microwave kuhle, kuye kwasetshenziswa kabanzi kuma-radomes.

Izakhiwo ezinhle zokushisa: Ukushisa okuphansi kwe-GRP, izinga lokushisa legumbi elingu-1.25 ~ 1.67kJ / (mhK), kuphela i-1/100 ~ 1/1000 yensimbi, kuyinto enhle kakhulu yokuvikela ukushisa. Endabeni yokushisa okufushane okuphezulu kakhulu, iyisivikelo sokushisa esifanele kanye nezinto ezingamelana nokushisa, ezingavikela indiza-mkhathi ku-2000 ℃ noma ngaphezulu ukuze imelane nokugeleza komoya okushesha kakhulu.

Ukuhleleka okuhle:

① Zonke izinhlobo zemikhiqizo yesakhiwo zingaklanywa ngendlela eguquguqukayo ngokwezidingo ukuze kuhlangatshezwane nezidingo zokusetshenziswa, okungenza imikhiqizo ibe nobuqotho obuhle.

2. Ungakhetha ngokugcwele izinto ezihambisana nokusebenza komkhiqizo, njengokuthi: angaklama ukumelana nokugqwala nokushisa okuphezulu, umkhiqizo unesiqondiso esithile samandla aphezulu, izakhiwo ezinhle ze-dielectric, njalo njalo.

Ubuciko obuhle kakhulu:

① Ngokuya ngesimo somkhiqizo, izidingo zobuchwepheshe, ukusetshenziswa kanye nenani lezinketho eziguquguqukayo zenqubo yokubumba.

② inqubo ilula, ingabunjwa kanye, umphumela wezomnotho uvelele, ikakhulukazi ezimweni eziyinkimbinkimbi, akulula ukwakha inani elincane lemikhiqizo, okugqame kakhulu enqubweni yayo yokuphakama.
