前處理工序：在正式開啟涂裝作業(yè)之前，對工件進行全面、細(xì)致的前處理是必不可少的重要環(huán)節(jié)。首先進行除油操作，利用專門配置的除油劑，將工件表面的油污徹底溶解并清除干凈，為后續(xù)工序創(chuàng)造良好的基礎(chǔ)條件。緊接著進行除銹工序，運用物理打磨或化學(xué)腐蝕等方法，將工件表面的銹跡徹底去除，還原工件原本的金屬光澤與質(zhì)地。隨后進入磷化工序，通過特定的化學(xué)反應(yīng)，在工件表面生成一層均勻且略帶粗糙感的灰色磷化膜。這層磷化膜不僅具有卓越的防銹性能，能夠有效抵御外界環(huán)境對工件的侵蝕，還能顯著增強后續(xù)噴塑層與工件表面的附著力，為提升涂裝質(zhì)量奠定堅實基礎(chǔ)。最后進行鈍化處理，進一步優(yōu)化工件表面的化學(xué)性質(zhì)，提高其耐腐蝕性與穩(wěn)定性，使工件以最佳狀態(tài)進入后續(xù)的涂裝工序。

Pre treatment process: Before officially starting the painting operation, comprehensive and meticulous pre-treatment of the workpiece is an essential and important step. Firstly, perform oil removal operation by using specially configured oil removal agents to thoroughly dissolve and clean the oil stains on the surface of the workpiece, creating a good foundation for subsequent processes. Next, the rust removal process is carried out, using physical polishing or chemical corrosion methods to completely remove the rust on the surface of the workpiece, restoring the original metallic luster and texture of the workpiece. Subsequently, it enters the phosphating process, where a specific chemical reaction generates a uniform and slightly rough gray phosphating film on the surface of the workpiece. This phosphating film not only has excellent anti rust performance, which can effectively resist the erosion of the workpiece by the external environment, but also significantly enhance the adhesion between the subsequent spray coating layer and the workpiece surface, laying a solid foundation for improving the coating quality. Finally, passivation treatment is carried out to further optimize the chemical properties of the workpiece surface, improve its corrosion resistance and stability, and enable the workpiece to enter the subsequent coating process in the optimal state.

預(yù)熱與底漆噴涂：經(jīng)過前處理的工件隨即進入預(yù)熱階段，通過精準(zhǔn)控制加熱溫度，使工件表面溫度適度升高。這一預(yù)熱過程能夠有效提升底漆與工件表面的親和性，為底漆的牢固附著創(chuàng)造有利條件。預(yù)熱完成后，便借助噴粉系統(tǒng)或噴漆設(shè)備對工件進行底漆噴涂作業(yè)。底漆作為整個涂層體系的基礎(chǔ)，其主要作用在于增強工件與面漆之間的附著力，同時為工件提供初步的防銹和防護功能，為后續(xù)的面漆涂裝打造穩(wěn)固的根基。

Preheating and Primer Spraying: After pre-treatment, the workpiece immediately enters the preheating stage, and the surface temperature of the workpiece is moderately increased by precisely controlling the heating temperature. This preheating process can effectively enhance the affinity between the primer and the workpiece surface, creating favorable conditions for the firm adhesion of the primer. After preheating is completed, the workpiece is sprayed with primer using a powder spraying system or spray painting equipment. As the foundation of the entire coating system, the main function of primer is to enhance the adhesion between the workpiece and the topcoat, while providing preliminary rust prevention and protection functions for the workpiece, creating a stable foundation for subsequent topcoat coating.

烘烤與表面噴漆：完成底漆噴涂后，工件進入烘烤環(huán)節(jié)。在特定的高溫環(huán)境下，底漆中的溶劑迅速揮發(fā)，涂層中的成分發(fā)生交聯(lián)反應(yīng)，逐漸固化成型。烘烤工序不僅能夠使底漆與工件表面緊密結(jié)合，還能提升底漆的硬度與耐磨性。烘烤完成后，進入表面噴漆工序。根據(jù)產(chǎn)品的設(shè)計要求與市場定位，精心挑選合適的液態(tài)涂料，運用噴漆設(shè)備對工件進行精細(xì)噴涂，以實現(xiàn)所需的色彩效果、光澤度以及表面紋理，賦予產(chǎn)品獨特的外觀魅力。

Baking and surface painting: After completing the primer spraying, the workpiece enters the baking process. In a specific high-temperature environment, the solvent in the primer rapidly evaporates, and the components in the coating undergo cross-linking reactions, gradually solidifying and forming. The baking process can not only tightly bond the primer with the surface of the workpiece, but also improve the hardness and wear resistance of the primer. After baking, enter the surface painting process. According to the design requirements and market positioning of the product, carefully select suitable liquid coatings, and use spray painting equipment to finely spray the workpiece to achieve the desired color effect, glossiness, and surface texture, giving the product a unique appearance charm.

高溫固化：最后，經(jīng)過表面噴漆的工件進入高溫固化烘道。在高溫的作用下，涂層中的各類成分發(fā)生更為深入、徹底的交聯(lián)反應(yīng)，形成一層結(jié)構(gòu)緊密、性能卓越的保護膜。高溫固化過程能夠顯著提升涂層的硬度、耐磨性、耐腐蝕性以及耐候性等關(guān)鍵性能指標(biāo)，確保涂裝效果具備長期的穩(wěn)定性與可靠性，使產(chǎn)品能夠在各種復(fù)雜的使用環(huán)境下始終保持出色的外觀與防護性能。

High temperature curing: Finally, the surface painted workpiece enters the high-temperature curing oven. Under the action of high temperature, various components in the coating undergo deeper and more thorough cross-linking reactions, forming a tightly structured and high-performance protective film. The high-temperature curing process can significantly improve key performance indicators such as hardness, wear resistance, corrosion resistance, and weather resistance of the coating, ensuring long-term stability and reliability of the coating effect, and enabling the product to maintain excellent appearance and protective performance in various complex use environments.
