Galvanized Square Steel Pipe Specifications
Kupisa dip galvanized square chubhu isimbi pombi chigadzirwa chakaitwa chakakosha kugadzirisa. Magadzirirwo ayo ekugadzira anosanganisira kunyudza sikweya chubhu mumvura yakanyungudutswa yezinki, zvichiita kuti kemikari iite pakati pezingi nepamusoro pesimbi, zvichigadzira dense layer ye zinc pamusoro pepombi yesimbi. Iyi inotevera ongororo yakadzama yehot-dip galvanized square rectangular mapaipi:
Pre treatment: Mapombi esimbi anotanga agarwa kuti abvise pamusoro pe iron oxide nezvimwe zvitsvina. Zvadaro, kuwedzera kucheneswa kunoitwa nekusanganisa ammonium chloride uye zinc chloride aqueous solution kuti ive nechokwadi chekuti pamusoro pepombi yesimbi yakachena uye isina tsvina.
Kupisa dip plating: Iyo pombi yesimbi isati yagadziriswa inotumirwa mutangi inopisa yekunyudza, iyo ine yakanyungudutswa zinc solution. Sora pombi yesimbi muzinc solution kwekanguva kuitira kuti zinc inyatsoita nepamusoro pesimbi, ichigadzira zinc iron alloy layer.
Kutonhodza uye mushure mekurapwa: Iyo galvanized simbi pombi inotorwa kubva kune zinc solution uye yatonhodzwa. Mamwe matanho emashure ekugadzirisa akadai sekuchenesa, passivation, nezvimwewo zvinogona kuitwa sezvinodiwa kuti uvandudze kusagadzikana kwekuora uye kunaka kwepamusoro kwepombi yesimbi.

Youfa Galvanized Square Steel Pipe Advantages uye Usages
Strong corrosion resistance:Iyo zinc layer iri pamusoro pekupisa-dip galvanized square chubhu inogona kudzivirira kuparara kwesimbi neokisijeni, acidic uye alkaline zvinwiwa, munyu wekupfapfaidza uye dzimwe nharaunda, nekudaro kuwedzera hupenyu hwesevhisi yechigadzirwa.
Uniform coating:Kuburikidza nekupisa-dip coating process, yunifomu zinc layer inogona kuumbwa pamusoro pesquare chubhu kuti ive nechokwadi chekusagadzikana kwekupokana kwepombi yese yesimbi.
Kunamatira kwakasimba:Iyo zinc layer inoumba chisungo chakasimba nechapamusoro chesimbi kuburikidza nekuita kwemakemikari, nekunamira kwakasimba uye kuramba kupepeta.
Good processing performance:Kupisa dip galvanized square chubhu ine yakanaka mechanical uye kugadzirisa zvivakwa, uye inogona kuumbwa kuita akasiyana maumbirwo akadai sekutonhora kutsika, kukunguruka, kudhirowa, kupeta, nezvimwewo pasina kukuvadza coating.
