Judgment of powder coating orange peel appearance
From shape visually or using mechanical methods of measurement shows instrument or via a bellows scan to assess and compare the powder coating orange peel appearance. (1) visual method In this test, the model of the double tube fluorescent. A model of reflective light source can be obtained by appropriately placed boilerplate. Qualitative analysis of the clarity of the reflected light from the visual assessment of the nature of the flow and leveling. In the case of poor flowability (orangeRead More …
Coating-forming process divided into melt coalescence,form a coating,leveling
Coating-forming process can be divided into melt coalescence to form a coating film leveling three stages. At a given temperature, the control molten coalescence rate the most important factor is the melting point of the resin, the viscosity of the molten state of the powder particles and the size of the powder particles. In order to best coalescence of molten shall as soon as possible, in order to have a longer time to complete the leveling phase flow effects. TheRead More …
Prevention of powder coating orange peel
The appearance of the coating is becoming increasingly important in the new equipment manufacturing (OEM) Painting. Therefore, one of the main objectives of the coatings industry is to make the final requirements of the user paints to achieve the best performance, which also includes the surface appearance of satisfaction. Affect the visual effects of the surface condition by the factors such as color, gloss, haze, and surface structure. The gloss and image clarity is commonly used to control the appearanceRead More …
What is the film hardness
The hardness of the powder paint film refers to the resistance of the paint film after drying has a solid, i.e. the film surface the role another on the greater hardness of the material performance. This resistance exhibited by the film can be provided by a certain weight of the load acts on the relatively small contact area, by measuring the ability of the film antideformation manifested, so the film hardness is a view showing one of the important propertiesRead More …
Suitable temperature for Waterproof coating
Waterproof coating selection characteristics of the solution, nano-ceramic hollow particles, silica alumina fibers, all kinds of reflective material as the main raw material, thermal conductivity only 0.03W/mK, can effectively suppress shielded infrared heat radiation and heat conduction. In the hot summer, at a temperature of more than 40 ℃, it would be inappropriate to do waterproof, for the following reasons: queous or solvent-based waterproof coating construction under high temperature conditions will rapidly thickens, cause priming difficulties, affect the construction quality;Read More …

Its film thickness of 15 ~ 25μm for welding, and does not affect the welding performance. The product can also be used as the use of anti-rust primer. For bridges, ships, offshore oil drilling platform, harbor facilities. Fourth, zincRead More …
Powder coatings and coating technology applications continue to expand
Due to the huge environmental pressure, powder coatings continue to replace liquid paint has become the mainstream, as powder coatings and coating technology improvements, powder coating applications. Powder coatings and coating technology improved main source white automobile industry, the appliance industry and general industrial demand growth, including raw materials, milling and coating technology show improvement. Powder coating applications in the automotive industry continues to expand, the car chassis, interior parts, wheels and body powder coating. The technical improvements of theRead More …
Manufacturers apply electrostatic powder coating to many types of products
Manufacturers may apply an electrostatic powder coating to many types of products. This type of finish is primarily used on metals ranging from steel to aluminum. It’s also used to finish a variety of consumer goods, from wire shelving to lawn furniture. Electrostatic powder coating is also used on cars and other vehicles, and remains a popular method of finishing exterior metal siding. This product may contain a variety of materials, depending on the product and manufacturer. Many include anRead More …
Five elements of the coating technology system
Coating technology, the definition of the concept of the painting process and the thinking of the current argument, I believe that the structure of the the coating technical knowledge system should be the main factors (elements) and a secondary factor; major factors should be divided into five major elements: coating materials (chemical materials and accessories), painting equipment (including tools), the painting environment, painting process, painting Management. Specific analysis and study of the five elements. The coating material is chemical materialsRead More …
Introduction of electrostatic spraying equipment
Dusting equipment electrostatic powder coating commonly known as “electrostatic spray”. The spray can be manual, automatic or manual + automatic. 100% of the spray material is a solid powder, the free powders can recycle the paint recycling rate up to 98%. Suspension of the transport system, a high degree of automation. The coated microporous less, good corrosion resistance, and can be a thick film. Electrostatic powder coating based on having an atomizing Tsui (the paint atomizing), and the discharge stageRead More …
