Txhaj tshuaj tua kab mob: tshuaj tsuag steel tua xeb Sa5 txwv, xeb, hlau zoo li hnyav hnyav-dawb xim hlau luster, nto roughness ntawm 40 ~ 70μm.
Txau txheej: ntxiv dag zog rau qib tshwj xeeb thee coal tar epoxy, los yog primer, sab plhu 5, qhov nruab nrab clip plaub txheej ntawm epoxy iav ntaub, 0.9 ~ 1mm thickness, coated nrog cov xim pleev xim rau ntawm txhua xim rau lub sij hawm kom qhuav cov ntawv nplaum.
Kev kuaj xyuas zoo: los ntawm kev tshuaj xyuas qhov muag, pleev xim rau qhov zoo li niaj hnub, du, tsis muaj sagging, tsis muaj npuas, tsis muaj wrinkles.Daim ntawv thov thickness gauge, sampling 5 feem pua, tag nrho ntsuas kom ua tiav cov thickness tsim, los yog thicken li painting.Tuav ntawm 5000V spark pinhole leak detector, pinhole thiab rwb thaiv tsev kuaj xyuas kom tsim nyog tsis muaj teeb meem.Adhesion los xyuas cov txheej txiav daim duab peb sab lub qhov ncauj, tuav tearing quab yuam yuav tsum yog ib qho nyuaj rau rub;yog rub tawm, tab sis thawj txheej ntawm primer yuav tsum tau txuas nrog cov yeeb nkab hlau zoo li, thiaj li tsim nyog.

Sab nraud corrosion ntawmcarbon steel yeeb nkabut cev
Siv cov txheej txheem STIC hnyav.
Txhaj tshuaj blasting: tag nrho cov me nyuam yeeb nkab xeb.
Txau cov txheej txheem tiv thaiv corrosion: Thaum xeb tsim nyog, siv lub tshuab cua tsis muaj lub siab siab los tshuaj tsuag thawj txheej ntawm cov xim liab primer kom txog rau thaum cov xim kom qhuav tsis-stick tes, thiab tom qab ntawd tshuaj tsuag qhov kawg ntawm ob zaj duab xis thickness ntawm 300μm.
Kev tshuaj xyuas xim: kev tshuaj xyuas qhov muag, tag nrho cov me nyuam tuab ntsuas siv qhov sib nqus tuab ntsuas ntsuas, tag nrho cov yeeb yaj kiab tuab ntawm ntau dua 600μm.

Internal txheej kav
faus cov kav dej thiab cov penstocks nyob rau hauv lub anti-corrosion, yog siv los dai galvanized barbed hlau, tshuaj tsuag compressive zog tsis tsawg tshaj li ntawm 30N / mm2 lub cement mortar hauv ob sab phlu.Cement mortar mix ratio, dej: cement: xuab zeb = 22:200:270;kev siv dej hauv tsev;#525 Portland cement;rigid, huv si, zoo-qib tej yam ntuj tso xuab zeb, av nplaum ntsiab lus yog tsawg tshaj li 2% particle loj tsawg tshaj li 2 hli.
