I-PrePreg yokupheka elula ayigcini ngokusebenza kahle kokwakhiwa, kepha futhi inokumelana kahle nama-acid ajwayelekile, i-alkali, usawoti kanye nezinto eziphilayo, kanye namandla amahle emishini ngemuva kokwelapha, njenge-frp yendabuko. Lezi zindawo ezinhle kakhulu zenza ama-preserts akhanyayo akhanyayo alungele amathangi okugcina amakhemikhali, ama-petroleum, amapayipi angaphezulu komhlaba nangaphansi komhlaba, njll., Ukukhiqiza imishini yokulwa nokuwohloka ngokusebenza okuhle.
1. Ukusetshenziswa kokulwa nokulwa nokugqwala kwethangi lokugcina uwoyela
Uma kuqhathaniswa nenqubo yokulungiswa kokuxhumana kokubumba i-lining, ngoba i-prepreg yokupheka ekhanyayo ingaqalwa ngamashidi noma ama-rolls, futhi kukhona amafilimu epulasitiki ezindaweni eziphakemeyo nangaphansi, okuguquguqukayo kwezokwakhiwa kancane, okuthuthukisa kakhulu indawo yokwakha nokuphepha. ucansi. I-prepreg evukela ukukhanya ekhanyayo ithambile futhi ingasikwa noma inqunywe ngokwezidingo zephrojekthi bese ifaka isicelo ngqo. Iphelelwe ukukhanya kwe-UV. Isikhathi sokuvula singamaminithi ayi-10 kuye kwangama-20. Kuthinteka kancane yimvelo futhi ingasetshenziswa unyaka wonke. Ukwakha, kungasetshenziswa ngokushesha ngemuva kokuphulukisa, ukunciphisa kakhulu isikhathi sokwakha nezindleko zabasebenzi.
E-Petrochina Chongming No. 3 Isiteshi segesi, i-prepreg ephethwe ukukhanya elungiselelwe yiMerican 9505 yasetshenziselwa ukuvuselela ukulungiswa kwethangi lokugcina uwoyela. Izimo ezifanele zokwakha zikhonjiswa esithombeni esingezansi. Ubulukhuni bungafinyelela kuma-60, futhi bunokumelana okuhle kokugqwala.

Ukumba okuqondayo kuyinqubo yokwakha yepayipi embonini yezobuchwepheshe yezobunjiniyela. Kusetshenziswa kabanzi ekwakhiweni kwamafutha, igesi yemvelo namapayipi athile kamasipala. Ungakuvikela kanjani i-anti-corringuon Outer Sheath ngesikhathi sokumba okuqondiswa kwepayipi bekulokhu kuyinkinga enzima emkhakheni wokwakha amapayipi. . Amapayipi amaningi aguquguqukayo asetshenziswa ekunqamukeni okuqondayo okuwela, futhi ubunzima besendlalelo sokulwa nokugqwala ebusweni bomzimba wepayipi akwanele. Ngesikhathi senqubo yokuhudula, ungqimba lwe-anti-corolusion luvame ukuqhekeka noma onqenqemeni lwezinto ezibonakalayo luyaliwe noma luphukile, oluthinta umphumela wokulwa nokugqwala futhi lubekezelela kakhulu ukuphepha kwepayipi. Ngenxa yezinkinga ezingenhla, i-prepreg evuthiwe ekhanyayo ingasetshenziswa njengongqimba oluvikelayo lwesendlalelo sangaphandle sepayipi. Izici zalo eziphambili zilukhuni oluphezulu, ukumelana kweSkrastiki kanye nokuphikiswa kokuphikisana, okungavikela kahle ungqimba lokulwa nokulwa.
Ukuqhathaniswa komkhono wokuzivikela okhanyayo ngaphambi nangemva kokusetshenziswa kwepayipi lokumba okuqondayo kuboniswa kulokhu okulandelayo:
Kungabonakala ngokusobala kusuka ekuqhathaniselweni okululaphekwe kokwelashwa okukhanyayo kunethonya elihle lokuvikela epayipini futhi kuthuthukise ukusebenza kwe-anti-torolusion yepayipi.
3. Ukusetshenziswa kokulwa nokugqwala kophahla lwamafutha okugcina igesi
Iningi lamathangi okugcina kawoyela namagesi ngamathangi ensimbi ensimbi. Ngoba uwoyela negesi kuvame ukuqukatha izinto ezilimazayo, ukugqwala kwamathangi ensimbi kubaluleke kakhulu. Isibonelo, ngaphansi kwesenzo sokushisa okuphezulu ethangini, amagesi ayingozi anjenge-oksijini encibilikisiwe, i-hydrogen sulfide kanye ne-carbon dioxide kuzokwenza ukulimala okuqinile phezulu kwethangi, kungadala ukulimala okukhulu kwamafutha kanye negesi kuphela, kepha futhi kwandisa ukuphepha. ingozi efihliwe. Ngokusebenzisa okuphephile kwamathangi okugcina kawoyela namagesi, ukulungiswa kwendawo noma ukushintshwa kwethangi phezulu kuyadingeka kaningi. Indlela yendabuko yokulungiswa kophahla lwethangi ukufaka esikhundleni seplate yensimbi yensimbi evulekile, edinga ukuthi ithangi liye limiswe, lihlanzwe, iyunithi yokwakha ukwakha izingqimba ngongqimba. Isikhathi sokwakha sinde futhi izindleko zokulungisa ziphezulu. Kodwa-ke, usebenzisa i-PrePreg ekhanyayo, i-Tank Top ekhona isetshenziswa njengethempulethi, futhi yakhelwe futhi inqunywe esizeni, futhi iboshelwe ngensimbi yasekuqaleni yensimbi ephakemeyo ukuze iphelele. Ngokwesisekelo sokugcina amandla aphezulu e-tank top, amandla engqimba yenhlanganisela iphindaphindwa futhi angasetshenziswa njengekhambi elisha lokulungiswa kophahla lwamathangi okugcina igesi.
Ngaphezu kwamasimu wokulwa nokukhulisa angenhla, ama-prepregs alulafu alulame angasetshenziswa emikhakheni yokulwa nokuwohloka okufana nama-linlings amachibi ezikhaleni ezingaphansi komhlaba, amapayipi angaphansi komhlaba, amathangi okugcina ama-clew. Njengamanje, iningi lamashidi okudla okulula emakethe yimikhiqizo engeniswayo, futhi izindleko ziphezulu, ezikhawulela uhlelo lwazo. Kodwa-ke, ngokusekelwa ngumbuso, ukunaka kwemakethe, kanye nokutshalwa kwemali okukhulayo kwezinsizakusebenza zokucwaninga nentuthuko, kuzoba nezinhlobo eziningi nezinhlobonhlobo zamashidi asetshenzisiwe asekhaya asetshenziswa emasimini ahlukile.
