The film door coating process is the advanced anticorrosion technology at present, the coating door and its series products. According to the use medium and working conditions, the polymer anticorrosion powder coatings with different formulas are applied to the metal surface evenly through special equipment. After curing and plasticizing, a layer of uniform and compact is formed on the metal surface. The glossy plastic coating has become a new type of steel composite flap door. It integrates the excellent mechanical properties of steel and the excellent chemical corrosion resistance of the polymer material, greatly prolongs the service life of the door, and has the unique advantages of anticorrosion, acid and alkaline, wear and wear, no scaling, lubrication, negative pressure and so on.

涂塑拍门特点：

Painting door features:

一、极强的附着力 钢管表面经过特殊处理，经特殊工艺固化，附着力≤30N/10mm。

1. The surface of the very strong adhesion steel pipe is specially treated and cured by special process. The adhesion force is less than 30N/10mm.

二、致密的内外树脂层 涂层厚度在0.5mm以上，绝无针孔，具有极好的耐腐蚀性能。

Two, dense inner and outer resin coating thickness is above 0.5mm, no pinhole, excellent corrosion resistance.

三、优越的机械性能， 可承受苛刻的使用条件 树脂层韧性好，机械强度高，具有很强的承受能力，性能大大提高。

Three, superior mechanical properties, can withstand harsh conditions of the use of resin layer toughness, mechanical strength, strong bearing capacity, performance greatly improved.

四 、耐腐蚀，不结垢 安装在污水管道上的涂塑拍门耐腐蚀，不结垢，特别输送高硫水质及输送含钙、镁等离子的水，节约维护费用，使用寿命远远高于其他产品。

Four, corrosion resistant, non fouling installed in the sewage pipe coating door corrosion resistance, no scaling, especially the transport of high sulfur water and transport of calcium, magnesium plasma water, saving maintenance costs, the service life is far higher than other products.

五、自润滑性 涂塑拍门内壁光滑，输送阻力小，在相同条件下，可提高输送能力30%.

Five. The self lubrication plastic coated flap has smooth inner wall and small conveying resistance. Under the same conditions, the conveying capacity can be increased by 30%..
