Ukuhlaziywa kwezinzuzo zemicu ye-basalt yamapayipi anomfutho ophezulu

I-Basalt fiberIpayipi elihlanganisiwe elinomfutho ophezulu, elinezici zokumelana nokugqwala, isisindo esincane, amandla aphezulu, ukumelana okuphansi kokuthutha uketshezi kanye nokuphila isikhathi eside kwenkonzo, lisetshenziswa kabanzi kumakhemikhali kaphethiloli, izindiza, ukwakhiwa kanye neminye imikhakha. Izici zalo eziyinhloko yilezi: ukumelana nokugqwala ku-H2S, i-CO2, amanzi anosawoti, njll., ukwakheka okuphansi kwe-wax, ukusebenza kahle kokugeleza, i-flow coefficient iphindwe ka-1.5 kunepayipi lensimbi, futhi ngesikhathi esifanayo, inamandla amahle kakhulu omshini, isisindo esincane, izindleko zokufaka eziphansi, impilo yesevisi yokuklama engaphezu kweminyaka engama-30, nakwamanye amaphrojekthi, ngisho nokusetshenziswa kweminyaka engama-50 akuseyona inkinga. Ukusetshenziswa kwalo okuyinhloko yilezi: uwoyela ongahluziwe, igesi yemvelo kanye namapayipi okudlulisa amanzi ahlanzekile; umjovo wamanzi angcolile, ipayipi likawoyela elingaphansi kanye neminye ipayipi yokucindezela okuphezulu; amapayipi enqubo kaphethiloli; amapayipi okudlulisa amanzi angcolile asezindaweni zikawoyela kanye namanzi angcolile; ipayipi lemithombo eshisayo njalo njalo.

Inqubo Eyinhloko:
Ukuqhathanisa nomehluko phakathii-fiberglasskanye nepayipi lokucindezela okuphezulu le-basalt fiber:
(1) i-fiber yokuchaza efanayo, i-pavement efanayo, imishini efanayo kanye nenqubo yayo yokuqinisekisa umehluko phakathi kwengcindezi ye-hydrostatic yepayipi le-fiber ye-basalt fiber/glass (DN50PN7, isibonelo, ukumelana nengcindezi ye-EP/CBF okungaba ngu-30MPa, ukumelana nengcindezi ye-EP/GF okungaba ngu-25MPa); izinga elifanayo lokucindezela, i-fiber ye-basalt uma iqhathaniswa ne-fiber yengilazi ukunciphisa i-pavement ngo-10%, 20% ukuqinisekisa izinga langempela lokumelana nengcindezi ye-hydrostatic (kuya ku-DN50PN7) Isibonelo, nciphisa izingqimba ezimbili zokumelana nengcindezi ye-EP / CBF okungaba ngu-25MPa).
(2) Ukuhlolwa kwakamuva ngemva kokunciphisa indlela yokuhamba ngezinyawo ukuze kuncishiswe ukusetshenziswa kwezinto zokusetshenziswa ukuze kuncishiswe izindleko zomkhiqizo kuye kwalawulwa, izinga lokumelana nokucindezela kwepayipi lisahlangabezana nezidingo zomklamo, izindlekoipayipi le-fiberglassuma kuqhathaniswa nokungabikho kokwanda okuphawulekayo.

Izinzuzo zokusebenza kwepayipi le-basalt fiber elinomfutho ophezulu:
(1) ukumelana okuhle kakhulu nokugqwala
I-Basalt fiberIsakhiwo sepayipi elinomfutho ophezulu sihlukaniswe ungqimba lwe-lining, ungqimba lwesakhiwo kanye nongqimba lwangaphandle oluvikelayo lwezingxenye ezintathu. Phakathi kwazo, ungqimba lwe-lining lunokuqukethwe okuphezulu kwe-resin, ngokuvamile okungaphezu kuka-70%, kanti okuqukethwe kwe-resin kongqimba lwalo lwangaphakathi olucebile nge-resin kuphakeme cishe ku-95%. Uma kuqhathaniswa nepayipi lensimbi, linokumelana nokugqwala okuphezulu kakhulu, njengezinhlobonhlobo zama-acid aqinile nama-alkali, izinhlobo ezahlukene zosawoti we-inorganic, imidiya ye-oxidizing, i-hydrogen sulfide, i-carbon dioxide, izinhlobo ezahlukene zama-surfactants, izixazululo ze-polymer, izinhlobo ezahlukene zezinyibilikisi eziphilayo, njll., inqobo nje uma kukhethwa i-matrix ye-resin enhle, ungqimba lwe-basalt olunomfutho ophezulu lungaba ukumelana kwesikhathi eside (i-acid egxilile, i-alkali enamandla, kanye ne-HF engafakiwe)
(2) Ukumelana okuhle nokukhathala kanye nokuphila isikhathi eside
Iphayiphi ye-basalt fiber ephezulu yokucindezela impilo yesevisi ingaphezu kweminyaka engama-20, futhi empeleni, ngokuvamile ngemva kweminyaka engaphezu kwengu-30 yokusetshenziswa isasebenza, futhi empilweni yayo yesevisi ayinayo insizakalo.
(3) Umthamo wokuthwala umfutho ophezulu
Izinga elijwayelekile lokucindezelai-basalt fiberipayipi elinomfutho ophezulu lingu-3.5MPa-25MPa (kufika ku-35 MPa, ngokuya ngobukhulu bodonga nokubalwa kwalo), uma liqhathaniswa namanye amapayipi angewona awensimbi, amandla okumelana nomfutho aphezulu.
(4) Isisindo esilula, ukufakwa okulula kanye nokuthuthwa
Ipayipi le-basalt fiber elinomfutho ophezulu liyi-1.6, ipayipi lensimbi noma ipayipi lensimbi elibunjiwe kuphela liyi-1/4 ~ 1/5, ukusetshenziswa okusebenzayo kubonisa ukuthi, ngaphansi kwengcindezi yangaphakathi efanayo, ububanzi obufanayo, ubude obufanayo bepayipi le-FRP, isisindo salo singama-28% wepayipi lensimbi.
(5) amandla aphezulu, izakhiwo ezinengqondo zemishini
Amandla okudonsa axial epayipi le-basalt fiber elinomfutho ophezulu angama-200 ~ 320MPa, aseduze nepayipi lensimbi, kodwa angaphezu kwamandla aphindwe kane, ekwakhiweni kwesakhiwo, isisindo sepayipi singancishiswa kakhulu, ukufakwa kulula kakhulu.
(6) Ezinye izakhiwo:
Akulula ukukala kanye ne-wax, ukumelana nokugeleza okuphansi, izakhiwo ezinhle zokuvikela ugesi, ukuxhumana okulula, amandla aphezulu, ukuhanjiswa kokushisa okuphansi, ukucindezeleka okuphansi kokushisa.
