Mechanical peeling indlela ye-3PE anti-corrosion coating
Njengamanje, ohlelweni lokugcinwa kwepayipi legesi, indlela yokucwenga ye-3PE anti-corrosion coating ihlongozwa ngokusekelwe ekuhlaziyweni kwesakhiwo kanye nenqubo yokumboza ye-3PE anti-corrosion coating [3-4].Umqondo oyisisekelo wokukhumula i-3PE anti-corrosion coating yepayipi lensimbi ukudala izimo zangaphandle (ezifana nokushisa okuphezulu kokushisa), ukubhubhisa ukunamathela kwezakhiwo eziyinhlanganisela ye-3PE anti-corrosion coating, futhi ufeze inhloso. yokuxebula ipayipi lensimbi.
Enqubweni yokumboza ye-3PE anti-corrosion coating, ipayipi lensimbi lidinga ukushisisa libe ngaphezu kuka-200 ℃.Kodwa-ke, uma izinga lokushisa liphezulu kakhulu, izinkinga ezilandelayo zizokwenzeka: ukusabela kokuphulukisa kwe-epoxy powder kuyashesha kakhulu, i-powder ayincibiliki ngokwanele, futhi ukwakheka kwefilimu kumpofu, okuzonciphisa ikhono lokubopha nge-surface. ipayipi lensimbi;ngaphambi kokuba i-adhesive iboshwe, iqembu elisebenzayo le-epoxy resin lidliwe ngokweqile., ingxenye noma ilahlekelwe ngokuphelele amandla okubopha amakhemikhali nge-adhesive;i-sintered epoxy powder layer ingase iphekwe kancane, ibonakale njengobumnyama futhi ibe phuzi, okuholela ekuhloleni ukuxebuka kwe-coating okungafanelekile.Ngakho-ke, lapho izinga lokushisa langaphandle lingaphezu kuka-200 ℃, i-3PE anti-corrosion coating kulula ukuyixebula.
Ngemva kokuba ipayipi legesi seligqitshiwe, ipayipi eligqitshiwe lidinga ukusikwa futhi lilungiswe ngenxa yezidingo zobunjiniyela bakamasipala;noma lapho ukuvuza kwegesi kudinga ukulungiswa, ungqimba olulwa nokugqwala kufanele luhlulwe kuqala, bese kwenziwa eminye imisebenzi yamapayipi.Njengamanje, inqubo yokukhumula i-3PE anti-corrosion coating yamapayipi ensimbi yilokhu: ukulungiswa kokwakhiwa, ukulungiswa kwepayipi kusengaphambili, ukwelashwa kokushisa, ukukhumula i-3PE anti-corrosion coating, kanye nomunye umsebenzi wokwakha.

① Ukulungiselela ukwakha
Amalungiselelo okwakha ikakhulukazi ahlanganisa: izisebenzi zokwakha kanye nezinsiza ezikhona, ukulungiswa okuphuthumayo kwamapayipi, ukwelashwa kokucindezeleka, ukumba umgodi wokusebenza, njll. Impahla yokwakha yokucwecwa kwe-3PE anti-corrosion coating ikakhulukazi ihlanganisa isibhamu sokusika igesi ye-acetylene, ifosholo eliyisicaba noma isando sesandla. .
② Ukwelashwa kwangaphambili kwepayipi
Ukwelashwa kwepayipi kuqala ikakhulukazi kuhlanganisa: ukunquma ububanzi bepayipi, ukuhlanza indawo yangaphandle yepayipi, njll.
③ Ukwelashwa kokushisa
Sebenzisa ithoshi yegesi ye-acetylene ukushisa ipayipi elakhiwe ngaphambili ekushiseni okuphezulu.Izinga lokushisa lelangabi lokusika igesi lingafinyelela ku-3000 ℃, kanti i-3PE anti-corrosion coating esetshenziswa epayipini legesi ingancibilika ngaphezu kuka-200 ℃.Ukunamathela kwe-coating kubhujiswa.
④ Ukucwecwa kwe-3PE anti-corrosion coating
Njengoba ukunamathela kwengubo ephethwe ukushisa kucekelwe phansi, ithuluzi lomshini elifana ne-spatula eliyisicaba noma isando sesandla singasetshenziswa ukuze kucwecwe ukumbozwa kwepayipi.

⑤ Omunye umsebenzi wokwakha

Ngemva kokucwecwa kwe-3PE evimbela ukugqwala, ukusika nokuguqulwa kwepayipi, ukushisela kanye nokumbozwa kwe-anti-corrosion coating entsha kufanele kwenziwe.
Indlela esetshenziswa njengamanje yokucwenga imanuwali ihamba kancane futhi umphumela wokuxebula uphakathi.Ngenxa yokulinganiselwa kwemishini yokwakha, ukusebenza kahle komsebenzi wokuhlubula akuphakeme, okuthinta ngokuqondile ukusebenza kahle kokulungisa okuphuthumayo kwepayipi legesi.Imikhawulo yempahla yokwakha ibonakala kakhulu kulokhu: a.Umkhawulo wendawo ye-spray flame yesibhamu sokusika igesi kuholela endaweni encane yokumboza encibilikiswe ukwelashwa kokushisisa kwegesi;b.Umkhawulo wokulingana phakathi kwamathuluzi afana namafosholo ayisicaba noma izando zezandla kanye nengaphandle lepayipi eliyindilinga Kuholela ekusebenzeni okuphansi kokucwecwa okunamathelayo.
Ngezibalo zesizinda sokwakha, isikhathi sokuxebuka se-3PE anti-corrosion coating ngaphansi kwamadayimitha amapayipi ahlukene kanye nosayizi wengxenye ezoxetshulwa satholwa.
