8 Meter Height Split Street Light Ncej

1. Thawj Txheej: Kub-Dip Galvanizing (HDG)

Qhov no yog theem tseem ceeb tshaj plaws rau kev ua haujlwm ntev - lub sij hawm kev ncaj ncees.

Txheej txheem:Tom qab acid pickling kom tshem tawm impurities, 8m steel seem yog submerged nyob rau hauv ib da dej ntawmmolten zinc ntawm $450^\\circ\\text{C}$.

Specifications:Peb tuav qhov tsawg kawg nkaus zinc txheej thickness ntawm$80\\text{--}85\\mu\\text{m}$(ua tau raws li ISO 1461 tus qauv).

Kev tiv thaiv sab hauv:Vim tias tus ncej yog submerged, zinc ntws mus rau sab hauv ntawm lub raj. Qhov no tiv thaivsab hauv rusting- feem ntau ua rau tsis ua hauj lwm hauv 8m ncej uas condensation accumulates ntawm lub hauv paus.

Kev tiv thaiv Sacrificial:Yog hais tias qhov chaw yog khawb thaum lub sij hawm installation, zinc ua raws li "sacrificial anode," oxidizing nws tus kheej los tiv thaiv cov hlau hauv qab los ntawm corroding.

2. Cov txheej txheem nruab nrab: Passivation & Pre- kev kho mob

Ua ntej cov xim kawg yog thov, galvanized nto undergoes chemical passivation.

Lub hom phiaj:Cov txheej no tiv thaiv kev tsim ntawm "dawb xeb" (zinc oxide) thiab ua raws li ib tugbonding agent. Nws ua kom cov hmoov txheej txheej adheres zoo kawg nkaus rau cov slick zinc nto, tiv thaiv tev lossis flaking dhau sijhawm.

3. Cov Txheej Txheem Kawg: Electrostatic Polyester Hmoov Txheej

Qhov no yog qhov pom tiav uas muab cov txiaj ntsig zoo nkauj thiab tiv thaiv UV.

Khoom siv:Peb sivSab nraum zoov-Qib Ntshiab Polyester Hmoov(feem ntau yog los ntawm cov thawj coj thoob ntiaj teb xws li AkzoNobel lossis PPG).

Daim ntawv thov:Cov hmoov yog electrostatically them los qhwv ib ncig ntawm tus ncej thiab tom qab ntawd kho hauv qhov kub siab - qhov cub kub ntawm$200^\\circ\\text{C}$.

Kev ua tau zoo:

UV Resistance:Formulated los tiv thaiv "chalking" los yog fading rau 5-10 xyoo nyob rau hauv ncaj qha tshav ntuj.

Impact Resistance:Muab lub plhaub tawv, hloov tau yooj yim uas tiv thaiv pob zeb chips thiab khawb thaum thauj thiab teeb tsa.

Decano Quality Assurance Tip:

Thaum soj ntsuam 8-meter ncej, ua tib zoo mloog rau lubpob qij txha(qhov twg cov seem sib txuas). Cov chaw no muaj kev sib txhuam thaum sib dhos. Peb pom zoo kom thov atxias-galvanizing kov-puajrau ib qho kev nthuav tawm thaum lub sij hawm qhov chaw teeb tsa kom muaj kev txuas ntxiv ntawm kev tiv thaiv kev tiv thaiv.
