A webinar from AIMCAL on November 10 promises to deliver an overview of drying coated webs as well as how to handle many of the defects that can arise during drying.
Scheduled for 11 a.m. ET, the one-hour session starts with the methods of supplying heat during drying. It also covers the various types of dryers, including impingement dryers, flotation dryers and several newer types. The web-based training session also discusses constant rate and falling rate drying, compares solvent with aqueous drying, and briefly mentions modeling drying and infrared and microwave heating.
The last section goes into drying defects and how to minimize them, including skinning, nonuniform distribution of binder and pigment, air-blown defects such as dryer bands and mottle, air bar rubs, blisters, blushing, blocking, cracking and curling due to drying stresses, starry night and reticulation.
