Umbhobho we-Epoxy we-FRP
Ingcaciso yeMveliso
Umbhobho we-epoxy we-FRP waziwa ngokusesikweni ngokuba ngumbhobho we-Glass Fiber Reinforced Epoxy (GRE). Ngumbhobho wezinto ezidityanisiweyo osebenza kakuhle, owenziwe kusetyenziswa inkqubo yokujika kwe-filament okanye efanayo, kunye neefayibha zeglasi ezinamandla aphezulu njengezinto zokuqinisa kunye ne-epoxy resin njenge-matrix. Iingenelo zayo eziphambili ziquka ukumelana nokugqwala okugqwesileyo (ukususa imfuneko yokukhusela), ubunzima obuncinci kunye namandla aphezulu (ukwenza kube lula ukufakwa kunye nokuthuthwa), ukuqhuba kobushushu obuphantsi kakhulu (ukubonelela ngobushushu kunye nokonga amandla), kunye nodonga lwangaphakathi olugudileyo, olungakhuliyo. Ezi mpawu zenza ukuba ibe yindawo efanelekileyo yokutshintsha imibhobho yendabuko kumacandelo afana nepetroleum, iikhemikhali, ubunjineli baselwandle, ubushushu bombane, kunye nonyango lwamanzi.
Iimpawu zeMveliso
I-FRP Epoxy Pipe (i-Glass Fiber Reinforced Epoxy, okanye i-GRE) inika indibaniselwano engcono kakhulu yeempawu xa ithelekiswa nezixhobo zemveli:
1. Ukumelana nokugqwala okungaqhelekanga
- Ukungakhuseleki kwiikhemikhali: Ayimelani kakhulu neentlobo ngeentlobo zezinto ezibangela ukubola, kuquka ii-asidi, ii-alkali, iityuwa, amanzi amdaka kunye namanzi olwandle.
- Ayinalo Ulondolozo: Ayifuni zigqubuthelo zokukhusela zangaphakathi okanye zangaphandle okanye ukhuseleko lwe-cathodic, nto leyo esusa ngokupheleleyo ulondolozo kunye nomngcipheko onxulumene nokugqwala.
2. Ubunzima obuKhanyayo kunye namandla aphezulu
- Uxinano Olunciphileyo: Inobunzima be-1/4 ukuya kwi-1/8 kuphela yombhobho wentsimbi, nto leyo eyenza kube lula kakhulu ukuhanjiswa kwezinto, ukuphakamisa, kunye nokufakela, nto leyo enciphisa iindleko zeprojekthi iyonke.
- Amandla Oomatshini Aphezulu: Inamandla aphezulu okutsalwa, ukugoba, kunye namandla okubetha, iyakwazi ukujongana noxinzelelo oluphezulu lokusebenza kunye nemithwalo yangaphandle.
3. Iimpawu zeHydraulic eziBalaseleyo
- I-Smooth Bore: Umphezulu wangaphakathi une-fruit factor ephantsi kakhulu, nto leyo enciphisa kakhulu ukulahleka kwentloko yolwelo kunye nokusetyenziswa kwamandla okupompa xa kuthelekiswa nemibhobho yesinyithi.
- Ukungakhuli: Udonga olugudileyo luyamelana nokunamathela kwesikali, intlenga, kunye nokungcoliswa kwezinto eziphilayo (njengokukhula kolwandle), lugcina ukuhamba kwamanzi kusebenza kakuhle ngokuhamba kwexesha.
4. Iipropati zoBushushu kunye nezoMbane
- Ubushushu: I-thermal conductivity yayo iphantsi kakhulu (malunga ne-1% yentsimbi), ibonelela ngobushushu obuhle kakhulu ukunciphisa ukulahleka kobushushu okanye ukwanda kolwelo oluthuthwayo.
- Ukufakwa kombane: Inika iipropati zokufakelwa kombane ezikumgangatho ophezulu, nto leyo eyenza ukuba ikhuseleke kwaye ifaneleke ukusetyenziswa kwiindawo zombane nezonxibelelwano.
5. Ukuqina kunye neendleko eziphantsi zomjikelo wobomi
- Ubomi Benkonzo Ende: Yenzelwe ubomi benkonzo beminyaka engama-25 nangaphezulu phantsi kweemeko zokusebenza eziqhelekileyo.
- Ulondolozo Oluncinci: Ngenxa yokunganyamezelani kwayo nokugqwala, inkqubo ayifuni kulungiswa rhoqo, nto leyo ebangela ukuba iindleko zomjikelo wobomi ziphantsi.

Ukongeza, ipayipi ye-FRP epoxy (GRE) isetyenziswa kakhulu kwizityalo zoshishino njengemibhobho yenkqubo yokuhambisa ulwelo lweekhemikhali olunokonakala kakhulu kunye namanzi amdaka. Kuphuhliso lweendawo zeoyile, isetyenziselwa ukusetyenziswa kokubola okuphezulu njengemigca yokuqokelela ioyile eluhlaza, imigca yokufakwa kwamanzi/ipolymer, kunye ne-CO2 injection. Ekusasazweni kwepetroli, yeyona nto ifanelekileyo kwimibhobho yesitishi segesi esingaphantsi komhlaba kunye neejetti zesiphelo seoyile. Ngaphezu koko, lukhetho olukhethwayo lwamanzi okupholisa amanzi olwandle, imigca yokucima umlilo, kunye nemigca yokukhupha ityuwa enoxinzelelo oluphezulu kunye ne-brine kwizityalo zokususa ityuwa.
