塗裝設計及施工技術

Design and Preparing Procedure for Painting

近年來，工業發展的結果，酸雨與污染日益增加，再加上地域本身嚴酷之腐蝕環境，使得金屬材料加速劣化，影響其美觀與使用壽命。日本曾於1974年進行之腐蝕防蝕調查中發表1份統計資料，即用於防蝕費用中，塗料佔了壓倒性的比例，約63%，可見塗料塗裝在防蝕對策上是最經濟，簡單且最有效的方法。我們都知道塗料是半成品，應該正確的選擇及使用適當的機具與方法，配合施工管理檢查，才能發揮完善的塗膜效果，而塗料本身一定要經由施工形成塗膜，始能發揮機能，可見塗裝工程是多麼重要。本文主要根據作者多年塗裝工程的經驗，介紹應用在鋼構上塗裝設計及施工技術，希望透過最新設備及技術資訊，能有效延長鋼材的使用壽命。

In these years, due to the growth of the industrial development, the continuous increasing of acid rain and air pollution and the existing adverse environment result in rapid corrosion of the structure materials not only in their appearance but also in its lifetime. There was a survey in corrosion prevention in Japan, 1974. It was reported that coating possesses 63% of the total cost of anti-corrosion consumption. This fact indicates that coating always is the most economic, simplest and the most effective way for the corrosion control compared with other methods. However, one thing must be realized that coating material is a semi-product which requires adequate application, facilities, method as well as management and inspection before it can fuction properly and become usefully effective film for corsosion control. Consequently, the emphasis on the coating film performance is absolutely necessary and significant. Recommendations contained herein are intended as a guide for painting design and preparing procedure. They are base to a considerable extent on the best current knowledge and experience by ourselves. This report is intended for the instruction and guidance in the techniques and practices used in steel structure. The pupose of this report is to present latest infomation about equipment and techniques used to obtain optimum life of coatings on steel.
