        粉末涂料以及涂裝技術應用領域
        來源:http://www.hnbjyygs.com/ 發布時間:2024-02-11

        由于巨大的環保壓力,粉末涂料不斷地取代液體油漆已經成為當今的主流,隨著粉末涂料以及涂裝技術的改進,粉末涂料的應用領域將更大。粉末涂料及涂裝技術的改進主要源白汽車行業、家電行業以及普通工業領域需求的增長,其中包括原材料、制粉和涂裝技術等的展改進。粉末涂裝在汽車行業的應用不斷擴大,汽車底盤、內飾件、輪轂和車身均開始采用粉末涂裝。汽車用粉末涂料的技術改進包括:透明粉末的透明性、附著力、流平性和抗紫外光性:在保證粉末涂料外觀和性能的前提下盡可能降低固化溫度;以及各種涂裝技術(如機器人技術、氣流控制技術和高上粉率技術)等。

        Due to enormous environmental pressure, powder coatings are constantly replacing liquid paints as the mainstream today. With the improvement of powder coatings and coating technology, the application field of powder coatings will be even larger. The improvement of powder coatings and coating technology mainly comes from the growth of demand in the white automotive industry, home appliance industry, and general industrial sectors, including the exhibition and improvement of raw materials, powder production, and coating technology. The application of powder coating in the automotive industry is constantly expanding, and the automotive chassis, interior parts, wheels, and body are all starting to use powder coating. The technological improvements of powder coatings for automobiles include: transparency, adhesion, leveling, and UV resistance of transparent powders: reducing the curing temperature as much as possible while ensuring the appearance and performance of powder coatings; And various painting technologies, such as robot technology, airflow control technology, and high powder rate technology.

        粉末涂料涂裝的預涂金屬板(卷材)在家電行業的應用快速增長,要求粉末涂料能在25~60s內完成熔融、流動流平和固化全過程,并同時保持良好的涂膜外觀與各種抗性。家電用粉末涂料必須具有一定的后成型性,其成型度取決于終用途。涂裝好的板材應當可以疊放在一起,普通金屬板材薄涂膜的涂裝線速度應當達到30~80fpm,卷材涂裝的線速度應達到100fpm。另外氣流控制(或降低)、上粉率或電荷轉移率應控制在佳狀態。在高的涂裝線速下固化涂膜外觀的改進是家電粉末涂料技術改進的主攻方向,它涉及到紅外光波長/光照強度與涂料及底材的匹配問題、快速流平的對流加熱和感應加熱固化方式、粉末涂膜表面連續性好的固化程序、以及整個固化體系的清潔程度。

        The application of pre coated metal sheets (coils) coated with powder coatings in the home appliance industry is rapidly increasing, requiring powder coatings to complete the entire process of melting, flow leveling, and curing within 25-60 seconds, while maintaining good coating appearance and various resistance. Powder coatings for household appliances must have a certain degree of post formability, and their formability depends on the end use. The coated sheets should be stacked together, and the coating speed of thin films on ordinary metal sheets should reach 30-80fpm, while the coating speed of coils should reach 100fpm. In addition, the airflow control (or reduction), powder loading rate, or charge transfer rate should be controlled in an optimal state. The improvement of the appearance of cured coatings at high coating line speeds is the main focus of the improvement of household appliance powder coating technology. It involves the matching problem of infrared wavelength/light intensity with coatings and substrates, fast leveling convection heating and induction heating curing methods, good surface continuity curing program for powder coatings, and the cleanliness of the entire curing system.

        汽車行業和家電行業的發展推動了特種粉末涂料體系和涂裝技術的開發,出現了適用于不同工藝的專用粉末涂料在普通工業涂料中的應用在不斷增長,逐步進入以前難以涉足的領域(由于顏色要求過多、涂裝速度過快、涂料滲色嚴重、涂層過多等)。在普通工業涂料市場上粉末涂料因可以提供各種批次的產品以滿足諸多小客戶的需求而成為另一大亮點。制粉設備供應商和原材料供應商的不斷增加也促使許多區域性的油漆供應商增設粉末涂料生產線,與此同時,成熟的歐洲市場卻不斷有新的粉末涂料原材料以及涂裝設備面世。

        The development of the automotive and home appliance industries has driven the development of special powder coating systems and coating technologies. The application of specialized powder coatings suitable for different processes in ordinary industrial coatings is constantly increasing, gradually entering areas that were previously difficult to explore (due to excessive color requirements, fast coating speed, severe paint bleeding, excessive coating, etc.). In the general industrial coating market, powder coating has become another highlight due to its ability to provide various batches of products to meet the needs of many small customers. The continuous increase in suppliers of powder equipment and raw materials has also prompted many regional paint suppliers to add powder coating production lines. At the same time, the mature European market is constantly seeing the emergence of new powder coating raw materials and coating equipment.

        總之,供應商數量的增加對于小中型的粉末用戶是為有利的,它們可以得到價格穩定的原材料,產品的實用性更強。但是粉末大客戶的發展往往只有少數特定供應商受益,使他們與粉末涂料、涂裝工藝、以及終用戶的關聯度更大。

        In short, the increase in the number of suppliers is beneficial for small and medium-sized powder users, as they can obtain raw materials with stable prices and stronger product practicality. However, the development of major powder customers often benefits only a few specific suppliers, which increases their relevance to powder coatings, coating processes, and end users.
