With the increasingly stringent environmental laws and regulations, water-based paint is also an inevitable choice for the application of automotive painting. We all know that automotive paint is more extensive: water-based anti-rust paint, water-based anti-corrosion paint, water-based glass paint, water-based plastic paint, water-based decorative paint, etc.
Waterborne metal paint has been widely used in the field of automobiles for several years, but most domestic waterborne paint manufacturers let downstream enterprises change their original painting equipment and processes to use their waterborne paint, and even some waterborne paint manufacturers invest to help them change their equipment. In fact, it is increasing costs and wasting resources. According to Xiaobian, at present, only a few domestic waterborne paint manufacturers with relatively senior qualifications are in the market. Using the existing painting equipment and technology of enterprises, we can directly apply water-based paint, such as industry benchmark infinite flower paint. Since 1998, we have been focusing on the research and development of water-based paint.
Liu Gong, Ministry of Infinite Flower Water Paint Transportation Metallic Paint Project, said that while attention should be paid to the operating characteristics of such equipment as paint mixing system, automatic spraying system, coating flash drying system and environmental temperature and humidity control system in spraying room, attention should also be paid to the surface roughness of electrophoretic coatings and the paint of solvent-based varnish (single component or double component) in the implementation of intermediate-free coating process. Film thickness and appearance fullness.
At present, the focus of development of infinite flower waterborne metal paint is to expand the temperature and humidity range of its construction environment as far as possible, promote the localization of key raw materials, and further reduce the material cost of waterborne metal paint.
Engine, transmission, axle and other power assembly parts, as well as chassis parts of locomotive represented by leaf spring, transmission shaft and shock absorber, most of these locomotive parts adopt low temperature (about 80 C) drying coating due to the particularity of the products (large thermal capacity, rubber and plastic parts or grease). Based on the requirement of environmental protection, more and more locomotive parts coating lines using solvent-based anticorrosive paint are gradually replacing with water-based anticorrosive paint.
Waterborne anti-rust and anti-fouling paint requires high cleanliness of workpiece surface, a little rust is not a problem, but there must be no oil stain, so the pretreatment requirements are strict, Infinite Flowers in view of this difficulty, introduced in 2007 and environmental protection and direct contact with the skin, better use of water-based rust remover and water-based oil remover, we collectively called surface treatment fluid.
The construction environment of waterborne anticorrosive paint is not particularly strict with temperature and humidity requirements, but too much humidity can easily cause problems such as film hanging, poor dryness and blistering. Generally, it can be solved by strengthening ventilation and setting low temperature gradient baking. In order to realize the “thick coating” of waterborne anticorrosive paint on locomotive parts, high-pressure airless spraying is also recommended for waterborne paint before spraying and under the technical communication with the manufacturer, whether water is added and diluted or not.
With the increasing attention paid by the state to the clean production of automobiles, Infinite Flower Paint vigorously promotes the development and application of water-based paints for automobiles such as metals, glass and plastics in China. Infinite Flower appeals for the cooperation of paint enterprises, painting equipment enterprises, research institutes and automobile enterprises to jointly tackle key problems and strive to launch a series of water-based coatings for locomotives with high cost performance and good applicability for painting. And realize industrialized intelligent application.
