Mechanical peeling usoro nke 3PE mgbochi corrosion mkpuchi
Ka ọ dị ugbu a, na usoro nhazi pipeline gas, a na-atụ aro usoro peeling nke 3PE mgbochi corrosion mkpuchi dabere na nyocha nke nhazi na usoro mkpuchi nke mkpuchi mkpuchi 3PE [3-4]. Echiche bụ isi nke ịpụpụ mkpuchi mgbochi corrosion 3PE nke ọkpọkọ ígwè bụ ịmepụta ọnọdụ mpụga (dị ka ikpo ọkụ dị elu), mebie adhesion nke ihe mejupụtara nke mkpuchi mgbochi corrosion 3PE, wee mezuo ebumnuche ahụ. nke peeling ígwè ọkpọkọ.
N'ime usoro mkpuchi nke mkpuchi mgbochi corrosion 3PE, ọkpọkọ ígwè ahụ kwesịrị ikpo ọkụ n'elu 200 ℃. Otú ọ dị, ọ bụrụ na okpomọkụ dị oke elu, nsogbu ndị a ga-eme: mmeghachi omume ọgwụgwọ nke epoxy ntụ ntụ dị ngwa ngwa, ntụ ntụ adịghị agbaze nke ọma, na mmepụta ihe nkiri ahụ adịghị mma, nke ga-ebelata ikike nke njikọ na elu. ọkpọkọ ígwè; tupu ekpuchie ihe nrapado ahụ, ndị na-arụ ọrụ resin epoxy na-eri oke. , akụkụ ma ọ bụ ọbụna kpamkpam na-efunahụ ike njikọ kemịkalụ na nrapado; na sintered epoxy ntụ oyi oyi akwa nwere ike dị ntakịrị coked, gosi dị ka ọchịchịrị na-acha odo odo, na-akpata na-erughị eru mkpuchi peeling nnyocha. Ya mere, mgbe mpụga okpomọkụ dị elu karịa 200 ℃, 3PE mgbochi corrosion mkpuchi dị mfe bee.
Mgbe e nwusịrị pipeline gas, ọ dị mkpa ka ebipụ ma gbanwee ya n'ihi mkpa nke injinia obodo; ma ọ bụ mgbe ọ dị mkpa ka a rụzie nkwụsị gas, a ga-ebu ụzọ kpochapụ oyi akwa mgbochi corrosion, mgbe ahụ, a ga-arụ ọrụ pipeline ndị ọzọ. Ka ọ dị ugbu a, usoro ịwepụ ọrụ nke 3PE mgbochi-corrosion mkpuchi nke gas ígwè ọkpọkọ bụ: ihe owuwu nkwadebe, pipeline pretreatment, okpomọkụ ọgwụgwọ, iwepụ 3PE mgbochi corrosion mkpuchi, na ndị ọzọ na-arụ ọrụ.

① Nkwadebe ihe owuwu
Nkwadebe ihe owuwu na-agụnye: ndị ọrụ na-ewu ụlọ na ụlọ ọrụ dị na ya, mmezi mberede nke pipeline, ọgwụgwọ ịda mbà n'obi, olulu olulu, wdg The ewu akụrụngwa maka peeling kwụsịrị 3PE mgbochi corrosion mkpuchi tumadi gụnyere acetylene gas igbutu egbe, ewepụghị iheejiegwala ma ọ bụ aka hama. .
② pretreatment pipeline
Pretreatment pipeline na-agụnyekarị: ikpebi dayameta ọkpọkọ, ihicha elu elu nke ọkpọkọ, wdg.
③ ọgwụgwọ okpomọkụ
Jiri ọwa gas acetylene kpoo ọkpọkọ a gwọchara ya na oke okpomọkụ. The ọkụ okpomọkụ nke gas ọnwụ nwere ike iru 3000 ℃, na 3PE mgbochi corrosion mkpuchi etinyere na gas pipeline nwere ike gbazee na n'elu 200 ℃. A na-ebibi adhesion nke mkpuchi ahụ.
④ Peeling nke mkpuchi mgbochi corrosion 3PE
Ebe ọ bụ na e kpochapụrụ ihe mkpuchi nke ikpo ọkụ na-ekpo ọkụ, a pụrụ iji ngwá ọrụ arụ ọrụ dị ka spatula dị larịị ma ọ bụ hama aka na-ehichapụ ihe mkpuchi ahụ site na ọkpọkọ.

⑤ Ọrụ ihe owuwu ndị ọzọ

Mgbe a kpochapụrụ ihe mkpuchi mgbochi nke 3PE, ịkpụ na ngbanwe nke pipeline, ịgbado ọkụ na mkpuchi nke mkpuchi mgbochi corrosion ọhụrụ kwesịrị ime.
Usoro ịkpụcha akwụkwọ ntuziaka a na-eji ugbu a na-adị ngwa ngwa yana mmetụta peeling bụ nkezi. N'ihi njedebe nke ngwá ọrụ ihe owuwu, nkwụsị ọrụ na-arụ ọrụ adịghị elu, nke na-emetụta kpọmkwem ọrụ nrụzi mberede nke pipeline gas. A na-egosipụta oke nke akụrụngwa ihe owuwu na: a. Mmachi nke ebe ọkụ ọkụ na-agba agba nke egbe egbe gas na-eduga na obere mpaghara nke mkpuchi gbazere site na ọgwụgwọ ikpo ọkụ gas; b. Mmachi nke dabara n'etiti ngwaọrụ ndị dị ka shọvel dị larịị ma ọ bụ hama aka na elu elu nke ọkpọkọ gbara gburugburu na-eduga na obere mkpuchi peeling.
Site na ọnụ ọgụgụ ebe a na-ewu ihe owuwu, a na-enweta oge peeling nke mkpuchi mgbochi corrosion 3PE n'okpuru ọkpọkọ ọkpọkọ dị iche iche na nha nke akụkụ a ga-ewepụ.
