General Knowledge of Aluminum Veneer

From the process of powder coat, the smaller semi picture thickness to your fluorocarbon coat should be higher than or equal to 30μm while the film thickness for your lace spray 40μm.

After drying, painting, and organic air coolingsystem, the high quality review before dentures departing the mill is going to be completed, mainly including picture depth detection and colour difference detection. Here's the introduction into the film thickness discovery.  There are three theories which have to be introduced temporarily that are local film depth, typical film thickness, and minimal regional film thickness. The local picture depth identifies the average value obtained by measuring the film thickness for three or more times over the inspected area covering no more than one ²on the cosmetic surface of the aluminum veneer. Normal picture thickness means the typical mean acquired by measuring partial picture thickness in less than 5 places (such as 4 corners and 1 principal stage ) on the ornamental surface of the aluminum veneer. While because of its minimal community film thickness, it's the minimal mean by measuring a number of searchable community film thickness worth on the cosmetic surface of the aluminum veneer. These three parameters are very significant.

The Inspection Requirements of the Paint Film Thickness of This Aluminum Veneer 

Nowadays, electrostatic spraying technologies is widely utilized in the procedure for spraying aluminum veneers from the business. On the other hand, the electrostatic spraying includes a higher demand on the humidity and temperature of this spray-painting room. Once handled incorrectly, the standard of the painting coat will be greatly influenced. In terms of the electrostatic spraying, then it's broken into powder coating and liquid coat.

Throughout the liquid spraying procedure, it takes that the typical film thickness to be no longer than 30μm (3×10∧-5m) for its next fluorocarbon coating whereas the smaller neighborhood film thickness must reach 25μm. It takes that the typical film thickness to be not less than 40μm for its next fluorocarbon coating whereas the smaller neighborhood film thickness needs to be equivalent or higher than 34μm.  The typical film thickness to your polyester liquid spray needs to be higher than or equal to 25μm while the smaller neighborhood film thickness 20μm.
