Kuwala kochiritsa prepreg sikungokhala ndi ntchito yabwino yomanga, komanso kumakhala ndi kukana kwa dzimbiri kwa ma acid ambiri, alkali, mchere ndi zosungunulira organic, komanso mphamvu zamakina pambuyo pochiritsa, monga FRP yachikhalidwe.Zinthu zabwino kwambirizi zimapanga prepregs zochilika zopepuka zopangira mankhwala, akasinja osungira mafuta, pamwamba pa nthaka ndi mapaipi apansi panthaka, ndi zina zotero, kuti apange zida zothana ndi dzimbiri zomwe zimagwira bwino ntchito.
1. Kugwiritsa ntchito anti-corrosion lining ya thanki yosungiramo mafuta
Poyerekeza ndi kukonza ndondomeko kukhudzana akamaumba akalowa, chifukwa kuwala-kuchiritsa prepreg akhoza prefabricated mu mapepala kapena masikono, ndipo pali pulasitiki mafilimu pa chapamwamba ndi m'munsi pamalo, zosungunulira volatilization pa yomanga ndi yaing'ono, amene kwambiri bwino yomanga. chilengedwe ndi chitetezo.kugonana.The osachiritsika kuwala-kuchiritsa prepreg ndi yofewa ndipo akhoza kudula kapena kudula malinga ndi zosowa za polojekiti ndiyeno ntchito mwachindunji.Amachiritsidwa ndi kuwala kwa UV.Nthawi yochiritsa ndi mphindi 10 mpaka 20 zokha.Sichikhudzidwa kwambiri ndi chilengedwe ndipo chingagwiritsidwe ntchito chaka chonse.Zomangamanga, zitha kugwiritsidwa ntchito mukangochiritsa, kuchepetsa kwambiri nthawi yomanga ndi ndalama zogwirira ntchito.
Ku PetroChina Chongming No. 3 gas station, prepreg yoyatsidwa ndi kuwala yokonzedwa ndi MERICAN 9505 idagwiritsidwa ntchito kukonzanso zingwe za thanki yosungiramo mafuta.Zomangamanga zoyenera zikuwonetsedwa mu chithunzi pansipa.Kuuma kumatha kufika 60, ndipo kumakhala ndi kukana bwino kwa dzimbiri.
2. Anti- dzimbiri ntchito mu njira pobowola payipi
Kubowola molunjika ndi njira yomanga mapaipi mumakampani opanga ukadaulo waukadaulo.Amagwiritsidwa ntchito kwambiri pomanga mafuta, gasi ndi mapaipi ena amtawuni.Momwe mungatetezere anti-corrosion sheath panja pobowola mapaipi nthawi zonse lakhala vuto lalikulu pantchito yomanga mapaipi..Mapaipi ambiri osinthasintha amagwiritsidwa ntchito podutsa pobowola, ndipo kuuma kwa anti-corrosion wosanjikiza pamwamba pa thupi la chitoliro sikokwanira.Panthawi yokoka, anti-corrosion wosanjikiza nthawi zambiri imasweka kapena m'mphepete mwa zigambazo zimapindika kapena kusweka, zomwe zimakhudza anti-corrosion effect ndikuyika pachiwopsezo chitetezo cha payipi.Poganizira mavuto omwe ali pamwambawa, prepreg yochiritsidwa bwino ingagwiritsidwe ntchito ngati gawo lotetezera lakunja kwa payipi.Mbali zake zazikulu ndi kuuma kwakukulu, kukana zikande komanso kukana kukangana, zomwe zimatha kuteteza anti-corrosion layer.
Kufananiza kwa manja oteteza kuwala kusanachitike komanso pambuyo pogwiritsira ntchito pobowola polowera kukuwonetsedwa pachithunzi chotsatirachi:
Zitha kuwoneka momveka bwino poyerekezera kuti kusanjikiza kowala kwa prepreg kumakhala ndi chitetezo chabwino papaipi ndikuwongolera magwiridwe antchito a payipi.
3. Kugwiritsa ntchito denga la tanki yosungiramo mafuta ndi gasi
Ambiri mwa matanki osungiramo mafuta ndi gasi ndi akasinja achitsulo.Popeza mafuta ndi gasi nthawi zambiri zimakhala ndi zinthu zowononga, kuwonongeka kwa matanki azitsulo kumakhala koopsa kwambiri.Mwachitsanzo, chifukwa cha kutentha kwapamwamba mu thanki, mpweya woipa monga mpweya wosungunuka, hydrogen sulfide ndi carbon dioxide udzasungunuka ndikupangitsa dzimbiri lamphamvu pamwamba pa thanki, kuwononga kwambiri pamwamba pa thanki. sikungoyambitsa kutaya kwakukulu kwa mafuta ndi gasi, komanso kumawonjezera chitetezo.ngozi yobisika.Kuti mugwiritse ntchito bwino matanki osungiramo mafuta ndi gasi, kukonzanso kwanuko kapena kusintha nsonga ya thanki kumafunika pafupipafupi.Njira yachikale yokonza denga la thanki ndikusintha mbale yachitsulo padenga lachitsulo, yomwe imafuna kuti thanki iyimitsidwe, kutsukidwa, gawo lomanga kuti lipange njira zachitetezo, ndi dipatimenti yachitetezo kuti ivomereze zigawo ndi zigawo.Nthawi yomanga ndi yayitali ndipo mtengo wokonzanso ndi wokwera.Komabe, pogwiritsa ntchito kuwala kochiritsa prepreg, thanki yomwe ilipo imagwiritsidwa ntchito ngati template, ndipo idapangidwa ndikudulidwa pamalowo, ndipo imalumikizidwa ndi thanki yoyambirira yachitsulo kuti ipange yonse.Pamaziko a kusunga mphamvu ya thanki yapachiyambi, Mphamvu ya chigawo chophatikizika imachulukitsidwa ndipo ingagwiritsidwe ntchito ngati njira yatsopano yothetsera denga la matanki osungiramo mafuta ndi gasi.
Kuphatikiza pa minda yomwe yatchulidwa pamwambapa, ma prepregs ochiritsa kuwala atha kugwiritsidwanso ntchito m'minda yolimbana ndi dzimbiri monga zomangira zamadzi m'malo apansi panthaka, mapaipi apansi panthaka, matanki osungiramo zinyalala, masitima apamadzi, ndi kukonzanso magetsi.Pakalipano, mapepala ambiri ochiritsa kuwala pamsika ndi zinthu zochokera kunja, ndipo mtengo wake ndi wokwera, zomwe zimalepheretsa kugwiritsa ntchito kwawo.Komabe, mothandizidwa ndi boma, chidwi cha msika, ndi kuchuluka kwa ndalama zafukufuku ndi chitukuko, padzakhala mitundu yambiri yosiyanasiyana ya mapepala a prepreg omwe amagwiritsidwa ntchito m'madera osiyanasiyana.
