Chifukwa chiyani ma valve amafunikira zokutira

Kuwonongeka ndi chimodzi mwazinthu zofunika zomwe zimayambitsa kuwonongeka kwa valve.Mu chitetezo cha valve, chitetezo cha valavu ndi nkhani yofunika kuiganizira.Kwa mavavu azitsulo, chithandizo cha zokutira pamwamba ndi njira yabwino yotetezera yotsika mtengo.

1. Kuteteza

Pambuyo pazitsulo zowonongeka ndi utoto, pamwamba pazitsulo zimakhala zotalikirana ndi chilengedwe.Chitetezo ichi chimatchedwa shielding effect.Koma ziyenera kunenedwa kuti utoto wopyapyala sungakhale ndi chitetezo chokwanira.Chifukwa polima yapamwamba imakhala ndi mpweya wokwanira, pamene chophimbacho chimakhala chochepa kwambiri, ma pores ake opangidwa amalola kuti mamolekyu a madzi ndi mpweya azidutsa momasuka.Mavavu osindikizidwa ofewa ali ndi zofunika kwambiri pa makulidwe a zokutira za epoxy pamtunda.Zitha kuwoneka kuti zokutira zambiri mtengo wake ndi waukulu kuposa pamwamba pazitsulo zosaphimbidwa.Pofuna kupititsa patsogolo kusasunthika kwa zokutira, anti-corrosion anti-corrosion ayenera kugwiritsa ntchito filimu yopangira filimu yokhala ndi mpweya wochepa wa mpweya komanso chodzaza cholimba chokhala ndi chitetezo chachikulu, ndipo panthawi imodzimodziyo, chiwerengero cha zigawo ziyenera kuwonjezeka. kotero kuti zokutira zitha kufika pakukhuthala kwina ndikukhala wandiweyani komanso wopanda porous.

2. Kuletsa dzimbiri

Pochita zigawo zamkati za zokutira ndi zitsulo, zitsulo pamwamba pake zimadutsa kapena chinthu chotetezera chimapangidwa kuti chiteteze chitetezo cha chophimba.Mavavu ogwiritsidwa ntchito pazofunikira zapadera ayenera kulabadira kapangidwe ka utoto kuti apewe zotsatira zoyipa.Kuphatikiza apo, valavu yachitsulo yomwe imagwiritsidwa ntchito papaipi yamafuta, zinthu zowonongeka zomwe zimapangidwa ndi mafuta ena komanso kuyanika kwa sopo zachitsulo zimathanso kugwira ntchito ngati organic corrosion inhibitors.

3. Chitetezo cha electrochemical

Electrochemical dzimbiri pansi pa filimuyi zimachitika pamene dielectric permeable ❖ kuyanika akumana ndi zitsulo pamwamba.Gwiritsani ntchito zitsulo zokhala ndi ntchito zambiri kuposa chitsulo ngati zodzaza zokutira, monga zinki.Idzagwira ntchito yoteteza ya anode yopereka nsembe, ndipo zinthu zowonongeka za zinki ndizofunika zinki kolorayidi ndi nthaka carbonate, zomwe zidzadzaza kusiyana kwa nembanemba ndikupanga nembanemba yolimba, yomwe imachepetsa kwambiri dzimbiri ndikutalikitsa moyo wautumiki wa valavu.
