COATING METHOD OF METAL PIPE INNER SURFACE
PROBLEM TO BE SOLVED: To provide a coating method of a metal pipe inner surface which can obtain a low-cost powder coating film without damaging a coating film appearance and adhesiveness of powder coating.SOLUTION: A coating method of a metal pipe inner surface for applying powder coating by spraying powder coating material on a metal pipe inner surface includes a first process of coating the metal pipe inner surface with the power coating material, a second process of supplying and depositing silica sand on the coated powder coating material by air pressure feeding, and a third process of coating the deposited silica sand with the powder coating material again to sandwich the silica sand with powder coating material layers.SELECTED DRAWING: Figure 1
【課題】粉体塗装における塗膜外観および密着性を損なうことなく、低コストな粉体塗膜を得ることができる金属管内面塗装方法を提供すること。【解決手段】金属管内面に粉体塗料を吹き付けて粉体塗装を行う金属管内面塗装方法において、金属管内面に粉体塗料を塗装する第１工程、塗装された粉体塗料の上に珪砂を空気圧送により供給し堆積させる第２工程、および堆積させた珪砂の上に粉体塗料を再度塗装する第３工程を含み、それにより珪砂を粉体塗料層で挟み込む金属管内面塗装方法。【選択図】図１
