Ko galvanized steel inoita ngura here? Zvingadziviswa sei?

Kana masimbi emarara achida kuchengetwa uye kutakurwa ari pedyo, matanho ekudzivirira akakwana anofanira kutorwa kudzivirira kuita ngura. Matanho chaiwo ekudzivirira ndeaya anotevera:

 

1. Nzira dzekurapa dzepamusoro dzinogona kushandiswa kuderedza kuumbwa kwevhu chena pamucheka.

Mapaipi ane galvanized uye maburi emagetsi anogona kuputirwa nedhiri yevarnish yakajeka mushure mekuputika. Zvigadzirwa zvakaita sewaya, mashizha, uye mesh zvinogona kuiswa wakisi nekuzorwa mafuta. Kune inopisa-dip galvanized structural components, chromium-yemahara passivation kurapwa inogona kuitwa pakarepo mushure mekutonhora kwemvura. Kana iyo galvanized parts inogona kutakurwa uye kuiswa nekukurumidza, hapana post-kurapa inodiwa. Muchokwadi, kana kurapwa kwepamusoro kuchidikanwa kune inopisa-dip galvanizing inonyanya kuenderana nechimiro chezvikamu uye zvinogona kuchengetedza mamiriro. Kana iyo nzvimbo yakavharidzirwa ichizopendwa mukati memwedzi mitanhatu, nzira yakakodzera yekurapa mushure mekurapa inofanira kusarudzwa kuti isakanganisa kunamatira pakati pe zinc layer nepende.

 

2. Zvikamu zvemagetsi zvinofanira kuchengetwa munzvimbo yakaoma, ine mhepo ine mhepo ine kuvhara kwakakodzera.

Kana mapaipi esimbi achifanira kuchengetwa kunze, zvikamu zvinofanirwa kusimudzwa kubva pasi uye kupatsanurwa nema spacers akamanikana kubvumira kuyerera kwemhepo pamusoro pese. Zvikamu zvinofanirwa kutenderedzwa kuitira kuti mvura ienderere mberi. Hazvifanirwi kuchengetwa pavhu rakanyorova kana kuti zvinomera zviri kuora.

 

3. Marata akavharwa haafanire kuiswa munzvimbo dzingangosangana nemvura, mhute, kunyungudika, kana kunyungudika kwechando.

Rinigalvanized steelinotakurwa negungwa, haifaniri kutakurwa senhumbi dzepasi kana kuiswa panzvimbo inochengeterwa ngarava, painosangana nemvura ine mvura. Pasi pema electrochemical corrosion conditions, mvura yegungwa inogona kuwedzera ngura chena. Munzvimbo dzemugungwa, kunyanya munyanza dzinopisa dzine hunyoro hwepamusoro, kupa nharaunda yakaoma uye nzvimbo dzakanaka dzekufemesa mhepo kwakakosha.
