GUJI HALKAN

EN 10248 Nooca Z ee Xaashida Birta ah ee ka hortagga daxalka

Ameerika: HDG (sida ku xusan ASTM A123, dhumucda zinc ≥ 85μm) + dahaarka 3PE ee ikhtiyaariga ah, oo lagu calaamadeeyay "U hoggaansan Deegaanka RoHS".

Koonfur-bari Aasiya: Iyada oo la qaadanayo hab isku dhafan oo ah galvanizing kulul (dhumucda lakabka zinc ≥ 100μm) iyo dahaarka dhuxusha epoxy, faa'iidada ugu weyn waxay ku jirtaa in aan miridhku dhicin xitaa ka dib 5,000 saacadood oo tijaabo ah oo lagu buufiyo milix, taasoo ka dhigaysa mid ku habboon jawiga cimilada badda ee kulaylaha.

EN 10248 Nooca Z ee Xirmada Tuubada Birta ah

Naqshadeynta: Isku xidhka qaabka Z, oo leh awood ≤1×10⁻⁷cm/s
Ameerika: Waxay buuxisaa shuruudaha ASTM D5887, habka tijaabada caadiga ah ee lagu galo biyaha iyada oo loo marayo aasaaska iyo darbiyada ilaalinta.
Koonfur-bari Aasiya: Biyaha dhulka hoostiisa ku jira oo aad u sarreeya iyo iska caabbinta daadadka ee gobollada kulaylaha iyo monsoon-ka

Habka Wax-soo-saarka Tuubada Birta ee ASTM Z Nooca

Xulashada Birta:

Dooro birta qaab-dhismeedka tayo sare leh iyadoo la raacayo shuruudaha hantida farsamada qaarkood.

Kuleylinta:

Kuleyli billets/slabs-ka ilaa ~1,200°C si aad u dabacsanaato.

Duubista Kulul:

Birta u samee qaab-dhismeedka Z-profile adigoo isticmaalaya mishiinnada duuban.

Qaboojinta:

Ku qabooji qaboojiyaha ama tuubada buufinta biyaha ilaa inta biyaha bartilmaameedka ah la gaarayo.

Toosinta iyo Jarida:

Ilaali saxnaanta dulqaadka inta aad qalabka u jarayso dhererka caadiga ah ama kuwa gaarka ah.

Kormeerka Tayada:

Samee kormeer cabbir, farsamo iyo muuqaal ah.

Daaweynta Dusha Sare (Ikhtiyaar):

Haddii loo baahdo, mari rinji, galvanize ama ka ilaali miridhku.

Baakadeynta iyo Rarista:

Xidh, ilaali, oo soo qaado rarida.

EN 10248 Nooca Z ee Xaashida Birta ah Codsiga ugu Muhiimsan

Darbiyada haynta- Waxay bixisaa taageero la isku halleyn karo oo ciidda ah si loogu isticmaalo dhulka iyo aasaaska.

Cofferdams– Darbiyada oo ilaaliya xakamaynta socodka biyaha ee meelaha dhismaha.

Mashruucyada Dekadda iyo Dekadda– Ku habboon darbiyada dekadda, dekedaha iyo codsiyada kale ee badda.

Xakamaynta Daadadka & Xasilloonida Streambank– Waxay xoojisaa bangiyada iyo meelaha laga galo iyadoo adeegsanaysa xoojinta fiilada, waxayna xakamaysaa nabaad-guurka.

Maxaad u Doorataa Tuubooyinka Birta Nooca Z

1. Marka modules-ka qaybtu isku mid yihiin, tuujinta xaashida nooca Z had iyo jeer way ka fudud tahay mitir laba jibbaaran marka loo eego tuujinta xaashida nooca U marka loo eego miisaanka.

2. Maadaama ballaca uu ka weyn yahay, waxaa loo baahan yahay xaashiyo yar, taas oo badbaadinaysa kharashka rakibidda ama qodista, iwm. sidoo kale tani waxay u fiican tahay biyaha aan biyuhu geli karin.

3. Loo isticmaalo sidii tuulmo buuxin ah oo leh tuubooyin bir ah iyo alwaaxyo H ah oo caadiyan loo isticmaalo in lagu gaaro modules aad u hiqh ah.
