Fluorocarbon powder coating
Fluorocarbon powder coating is a poly-vinylidene fluoride resin nCH2CF2 baking (CH2CF2) n (PVDF) as the base material or with metallic aluminum powder coating made for the toner. Bond of fluorine / carbonized the fluorocarbon base material in the chemical structure in conjunction with such a structure of the nature of having a short key is combined with hydrogen ions most stable solid combination, on the stability and solidity of the chemical structure different physical properties of the fluorocarbon paint inRead More …
Important to monitor the environmental conditions during powder paint application
Why is it important of Monitoring environmental conditions in application of powder paint? To help avoid powder paint substandard construction, surface treatment and paint under the best environmental conditions, lining construction is very important. The most important task of the environmental control of temperature, surface temperature, humidity and dew point control. The dew point is the moisture just the temperature when dew formation in the surface layer of the steel. Moisture will cause the steel to rust in just blastedRead More …
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 …
