Jiangsu Driving corrosion engineering / Hunan driving a preservative project, driving embalmed and requirements (1) with a fine sandpaper old alkyd red lead paint, and remove any residual dross rust and wear parts; (2) grinding is completed After thorough cleaning and sanding dust debris. (3) prior to coating application, shall be subject to the grass-roots Party organizations such Supervisor acceptance, make sure to remove all oil, dust, grease, dirt, rust and other external attachments only after formal coating application to ensure coating equipment quality and service life. (4) should be checked before each coating on a substrate or finishes on whether there is oil, dust, grease, dirt or other external attachments. (5) Before priming a first pre-coat primer coating difficult position in the corners, weld seams and polished parts of rust, etc., to ensure that parts of the film thickness to meet the requirements 2 Construction environmental requirements (1) Temperature: Minimum 4oC, the highest 35oC, at least 3oc above dew point Relative humidity: up to 85% (2) or three or more windy rainy day, do not allow the construction. After construction not rain within 8 hours (note the weather forecast, reasonable arrangements period), after the rain 1 to 2 days before being subject to the base construction and dried again.
