Mechanical Properties Of Powder Coatings After Curing Jul 16, 2022

Mechanical Properties Of Powder Coatings After Curing 1. Insufficient curing A) raise the baking temperature to make it reach the temperature required by the process B) extend the workpiece baking time to make it reach the time required by the process 2. Excessive baking and curing, making the cross-linked structure of the coating film brittle Properly reduce the baking temperature...

The Powder Coating Processing-Less Waste, High Powdering Rate Jul 15, 2022

Why is the powder loading rate not high in the powder coating process? 1. Insufficient static voltage of the gun head, so that the powder is not sufficiently charged, not easy to adsorb to the surface of the workpiece Solution: A）Check the static voltage and adjust it up appropriately B）Clean the electrode of the gun head 2. The static voltage is too high so the Faraday effect is pronounced and th...

Powder Coating Solution-Powder coating processing Jul 14, 2022

Powder Sprayed Onto The Workpiece With Powder Clumps Produced 1. Moisture or oil in the compressed air Solution： Checking the purification of gas sources 2. High content of ultrafine powder in the powder, too much ultrafine powder leads to increased surface energy, easy to produce agglomeration phenomenon Solution： A) Reduce the amount of recycled powder added to the original powder B) ...
