Ndi chitukuko chosalekeza chachuma cha China, dzikolo likukula mwamphamvu makampani opanga mphamvu.Mapaipi a mtunda wautali wamafuta ndi gasi ndi njira yofunikira yotetezera mphamvu.Mu njira yopangira anti-corrosion ya mapaipi amafuta (gasi), chithandizo chapamwamba cha anti-corrosion spiral steel mapaipi amatsimikizira moyo wautumiki wa mapaipi.Chimodzi mwa zinthu zofunika kwambiri ndi mfundo yakuti anti-corrosion layer ndi chitoliro chachitsulo chikhoza kuphatikizidwa mwamphamvu.Malinga ndi kutsimikizira kwa bungwe lofufuza, moyo wa anti-corrosion wosanjikiza umadalira mtundu wa zokutira, mtundu wa zokutira ndi malo omanga.Chithandizo chapamwamba cha anti-corrosion spiral steel chitoliro chimakhudza moyo wa anti-corrosion wosanjikiza pafupifupi 50%.Choncho, ayenera mosamalitsa mogwirizana ndi wosanjikiza odana ndi dzimbiri.Kukhazikitsa zofunika padziko zitsulo mipope, mosalekeza kufufuza ndi mwachidule, ndi mosalekeza kusintha pamwamba mankhwala njira mipope zitsulo.

Kodi chitoliro chachitsulo chokwera pafupipafupi chotsutsana ndi dzimbiri chitani?

1. kuyeretsa

Ntchito zosungunulira ndi emulsion kuyeretsa pamwamba zitsulo kuchotsa mafuta, mafuta, fumbi, lubricant ndi ofanana organic kanthu, koma sangathe kuchotsa dzimbiri, sikelo, flux, etc. padziko zitsulo chitoliro, choncho ntchito monga njira yothandizira pakupanga anti-corrosion ya chitoliro chachitsulo..

2. chida dzimbiri kuchotsa

Pamwamba pa chitoliro chachitsulo chimapukutidwa pogwiritsa ntchito burashi yawaya kapena zina zotere kuti achotse sikelo yomasuka kapena yokwezeka, dzimbiri, slag yowotcherera, ndi zina zotero.Kuchotsa dzimbiri kwa chida chamanja kumatha kufika pamlingo wa Sa2, ndipo kuchotsa dzimbiri kwa chida champhamvu kumatha kufika pamlingo wa Sa3.Ngati pamwamba pazitsulo zazitsulo zimatsatiridwa ndi chitsulo cha oxide sikelo, mphamvu yochotsa dzimbiri ya chidayo si yabwino, ndipo kuya kwa nangula komwe kumafunika kuti pamangidwe odana ndi dzimbiri sikungakwaniritsidwe.

3. pickling

Nthawi zambiri, kuyeretsa mankhwala ndi electrolysis ntchito pickling mankhwala.Anticorrosive spiral steel chitoliro chimangogwiritsidwa ntchito ndi pickling yamankhwala, yomwe imatha kuchotsa sikelo, dzimbiri ndi zokutira zakale, ndipo nthawi zina imatha kugwiritsidwa ntchito ngati kuchiritsanso pambuyo pa kuphulika kwa mchenga ndi kuchotsa dzimbiri.Ngakhale kutsuka kwa mankhwala kumatha kukhala paukhondo ndi kukhwimitsa zinthu, njira yake ya nangula ndiyosazama ndipo ndiyosavuta kuipitsa chilengedwe.
