Ipayipi elinomfutho ophezulu elihlanganisiwe we-basalt fiber, elinezici zokumelana nokugqwala, isisindo esincane, amandla aphezulu, ukumelana okuphansi ukudlulisa uketshezi nokuphila isikhathi eside kwenkonzo, lisetshenziswa kabanzi kumakhemikhali kaphethiloli, ezindiza, ekwakheni nakwamanye amasimu. Izici zalo eziyinhloko yilezi: ukumelana nokugqwala kwe-H2S, i-CO2, i-brine, njll., ukuqongelela okuphansi, ukugcotshwa kwe-waxing okuphansi, ukusebenza kahle kokugeleza, i-flow coefficient iphindwe ka-1.5 kunepayipi lensimbi, kuyilapho inamandla amahle kakhulu omshini, isisindo esincane, izindleko zokufaka eziphansi, impilo yokuklama engaphezu kweminyaka engama-30, kwamanye amaphrojekthi, ngisho nokusetshenziswa kweminyaka engama-50 akukabi nenkinga. Izicelo zayo eziyinhloko yilezi: uwoyela ongahluziwe, igesi yemvelo kanye namapayipi okudlulisa amanzi ahlanzekile; amapayipi anomfutho ophezulu njengokufakwa kwendle kanye namapayipi kawoyela angaphansi; amapayipi enqubo kaphethiloli; amapayipi okudlulisa amanzi angcolile asezindaweni zikaphethiloli kanye namanzi angcolile; amapayipi e-spa, njll.
Izinzuzo zokusebenza kwepayipi le-basalt fiber elinomfutho ophezulu:
(1) Ukumelana okuhle kakhulu nokugqwala
Isakhiwo sepayipi le-basalt fiber elinomfutho ophezulu sihlukaniswe izingxenye ezintathu: ungqimba lwangaphakathi, ungqimba lwesakhiwo kanye nongqimba lwangaphandle lokuvikela. Phakathi kwazo, okuqukethwe kwe-resin kwengqimba yangaphakathi kuphezulu, ngokuvamile kungaphezu kuka-70%, kanti okuqukethwe kwe-resin kwengqimba ecebile nge-resin ebusweni bayo bangaphakathi kuphakeme cishe ku-95%. Uma kuqhathaniswa namapayipi ensimbi, inokumelana nokugqwala okuphezulu kakhulu, njenge-asidi enamandla ne-alkali, izixazululo ezahlukene zikasawoti ezingaphili, imidiya ye-oxidation, i-hydrogen sulfide, i-carbon dioxide, ama-surfactants ahlukahlukene, izixazululo ze-polymer, izinyibilikisi ezahlukahlukene zezinto eziphilayo, njll. Uma nje i-matrix ye-resin ikhethwe kahle, amapayipi e-basalt fiber anamandla aphezulu angamelana nesikhathi eside (ngaphandle kwe-asidi egxilile, i-alkali enamandla kanye ne-HF)
(2) Ukumelana okuhle nokukhathala kanye nokuphila isikhathi eside
Isikhathi sokuklama sepayipi elinomfutho ophezulu we-basalt fiber singaphezu kweminyaka engama-20, futhi empeleni, livame ukuba liphelele ngemva kweminyaka engaphezu kwengu-30 lokusetshenziswa, futhi alinakekelwa ngesikhathi sokuphila kwalo kokusebenza.
(3) Umthamo wokuthwala umfutho ophezulu
Izinga elijwayelekile lokucindezela kwepayipi le-basalt fiber elinomfutho ophezulu lingu-3.5 MPa-25 MPa (kufika ku-35 MPa, kuye ngokuthi udonga lubanzi kangakanani kanye nokubalwa kwalo), elinokumelana okuphezulu kokucindezela uma kuqhathaniswa namanye amapayipi angewona awensimbi.
(4) Isisindo esincane, kulula ukuyifaka nokuyithutha
Ubukhulu bepayipi elinomfutho ophezulu wefayibha ye-Xuan Yan bungaba ngu-1.6, okuyi-1/4 kuya ku-1/5 kuphela yepayipi lensimbi noma ipayipi lensimbi elibunjiwe, futhi ukusetshenziswa kwangempela kukhombisa ukuthi ngaphansi kwesisekelo sokucindezela kwangaphakathi okufanayo, isisindo sepayipi le-FRP elinobubanzi nobude obufanayo cishe singama-28% alepayipi lensimbi.
(5) Amandla aphezulu kanye nezakhiwo ezinengqondo zemishini
Ipayipi le-basalt fiber elinomfutho ophezulu linamandla okuthambekela kwe-axial angu-200-320MPa, eduze kwepayipi lensimbi, kodwa amandla alo aphindwe kane, ekwakhiweni kwesakhiwo, isisindo sepayipi singancishiswa kakhulu, ukufakwa kulula kakhulu.
(6) Ezinye izakhiwo:
Akulula ukukala kanye ne-wax, ukumelana nokugeleza okuncane, izakhiwo ezinhle zokuvikela ugesi, ukuxhuma okulula, amandla aphezulu, ukuhanjiswa kokushisa okuphansi, ukucindezeleka okuphansi kokushisa.
