Quality management has no eternal answer, only the eternal question, there is no best, only better, which requires us to start from the little things, do a good job in detail, grasp the quality!
Automotive coating divided to base coat、primer、top coat and auxiliary materials (hardener、thinner, etc.), different paint have different purposes, and the test items is not the same. The test of finished coating divided to the basic performance test, construction paint routine test, third-party test. Today we would like to show you an acceptable quality of product need to pass which tollgates, Let’s go:
1, The basic performance test of paint
For the well deployed original paint, first need to check the appearance: Requires uniform appearance,no agglomeration, knot skin, wire drawing and impurities; Second, check the specific gravity, viscosity, fineness, solid content, color and other projects.
The formula designed by the R&D department, its proportion, solid content,viscosity, and other items have a definite formulation of theory, if in the production process of a project the actual test value exceeds the formulation of the theory of value, indicating that the abnormal situation in the process of production, the products need to stop production, find the cause of the problem, to solve the problem. Only allow to enter the construction process wait until to all test items meet the technical standards.
2, The film routine test.
Production of each product, before packaging, need to be sprayed construction, testing film properties; Specific operation according to the different kinds of products and with appropriate construction methods, add the corresponding accessories for the deployment of construction. Such as 2K tint paint product, according to different seasons (summer with slow drying, spring and autumn with standard drying, winter with fast drying), supporting the use of hardener and thinner, according to the mix ratio main paint:hardener:thinner=2:1:0.4(by weight), stirring evenly and spraying. Need to observe every paint spray effect during the construction, and then observe the wet film leveling, the surface roughness, foreign particles, oil concave eye points etc. Then put a wet plate into an 80 ℃ oven to dry, and place one into the clean box to dry in chamber temperature. After 30 minutes, remove the baked plate to observe whether there are particles, sunken eyes, orange peel paint film criticism, then tested the gloss, adhesion, flexibility, pencil hardness, impact strength and other projects. After one hour, take from the holographic plate, viewing the film state, dry conditions, film criticism and so on. When all items meet all the technical requirements, we issue the packing list. At this time the product can evacuation production areas, to the packaging area, in accordance with the appropriate filtration requirements for packaging.
3, Paint type test project
In carrying out routine testing program, our company also carried out some long inspection cycle type test items. Such as the storage stability of the original paint, crust, precipitation, film water resistance, oil resistance, temperature change resistance, aging project. Storage stability is the canned paint into the oven at 50℃ stored for 30 days and then can check whether a crust, precipitation. Water resistance of film, accelerated aging project can judge the coating can meet customer needs, determine the coating such as quality.
4, Third-party test.
Our products are not only the needs of the company's internal tests, and also accept third-party laboratory testing; third-party laboratories are currently working with us are SGS, National Coatings testing center in Shunde, Guangdong Coating Quality Supervision and Inspection Station.Excellent products, outstanding construction, above average performance and environmental protection philosophy enable our products successfully passed the supervision and testing again and again, so that customer satisfaction is our progressive power.
"Today's quality" is "tomorrow's market", let us put the quality concept in mind, the implementation of the work of every day, every moment of behavior, for all users to provide quality, stable quality products.
