一、前期準備階段

　　1、 Pre preparation stage

　　表面清潔處理

　　Surface cleaning treatment

　　在開始涂裝作業之前必須徹底清除鐵藝護欄表面的灰塵油漬等污染物，建議使用專業清潔劑配合無塵布進行深度清潔，以確保后續漆層能夠均勻牢固地附著在金屬基材上。

　　Before starting the painting operation, it is necessary to thoroughly remove dust, oil stains, and other pollutants from the surface of the wrought iron guardrail. It is recommended to use professional cleaning agents and dust-free cloths for deep cleaning to ensure that the subsequent paint layer can be evenly and firmly attached to the metal substrate.

　　基材打磨工序

　　Substrate polishing process

　　采用砂紙、鋼絲球或電動打磨設備對護欄表面進行系統性打磨處理，通過創造適當粗糙度的基底面來顯著提升油漆涂層與金屬之間的結合力，這是確保涂裝持久性的關鍵步驟。

　　Using sandpaper, steel wire balls, or electric polishing equipment to systematically polish the surface of the guardrail, significantly improving the adhesion between the paint coating and the metal by creating a base surface with appropriate roughness. This is a key step in ensuring the durability of the coating.

　　二、涂裝實施流程

　　2、 Painting implementation process

　　底漆涂布工藝

　　Primer coating process

　　在正式涂刷面漆前需要先施作具有防腐防銹功能的專用底漆，這不僅能優化面漆的流平性和覆蓋效果，更能通過化學轉化層顯著增強涂層體系的整體附著力，建議根據環境腐蝕程度選擇合適的底漆類型與色系。

　　Before formally applying the topcoat, a specialized primer with anti-corrosion and anti rust functions needs to be applied first. This not only optimizes the leveling and coverage effect of the topcoat, but also significantly enhances the overall adhesion of the coating system through a chemical conversion layer. It is recommended to choose the appropriate primer type and color scheme according to the degree of environmental corrosion.

　　面漆施工要點

　　Key points for topcoat construction

　　待底漆完全固化后即可進行面漆涂裝，應選用耐候性優異的專用金屬漆，使用優質毛刷或滾筒工具采用十字交叉法施工，確保漆膜厚度均勻且無流掛現象，特別注意邊角部位的覆蓋完整性。

　　After the primer is completely cured, the topcoat can be applied. Special metal paint with excellent weather resistance should be selected, and high-quality brushes or roller tools should be used for cross cross construction to ensure uniform film thickness and no sagging phenomenon. Special attention should be paid to the integrity of the coverage of the corners.

　　裝飾細節處理

　　Decorative detail processing

　　對于護欄上的雕花鏤空等復雜造型部位，需提前選用特制細尖毛筆進行預涂裝，沿著花紋輪廓精細作業以避免出現漏涂死角，建議在光線充足環境下操作以保證細節處理精度。

　　For complex shapes such as carved and hollowed out parts on guardrails, it is necessary to use a specially designed fine tipped brush for pre coating in advance. Fine operation should be carried out along the contour of the pattern to avoid blind spots. It is recommended to operate in a well lit environment to ensure the accuracy of detail processing.

　　面漆強化涂層

　　Topcoat reinforced coating

　　為獲得更理想的裝飾保護效果，可在首層面漆表干后追加第二遍涂裝，這樣既能增強色彩飽和度呈現更鮮艷的視覺效果，又能通過增加整體漆膜厚度來提升護欄的長期防護性能。

　　To achieve a more ideal decorative protection effect, a second coat of paint can be added after the first layer of topcoat has dried. This can enhance color saturation and present a more vivid visual effect, while also improving the long-term protective performance of the guardrail by increasing the overall paint film thickness.
