Factors Affecting the Coating Amount of Plaster Coating Machines
The angle between the blade and the tangent line of the patterned roller is generally between 15° and 30°. If the angle is too large, the blade will almost press against the patterned roller, and since the surface of the patterned roller is not smooth, it can cause vibrations or bouncing of the elastic blade when it rotates at high speed. This results in the solution being splashed, leading to uneven coating and significant differences in coating amounts. Additionally, a larger angle can also easily damage the blade edge.

Examples of Antipyretic Patch Formulations and Production Processes
The main structure of the heat patch consists of three parts: a non-woven fabric substrate, a gel layer as the main body, and an anti-adhesion layer. The hydrophilic gel in the gel layer has good energy conversion capabilities, which can stimulate the cold receptors of nerve endings, producing a cooling sensation. After applying the heat patch, the heat from the skin is absorbed by the polymer gel layer and dissipated through vaporization, continuously removing heat from the body. The cooling time of the heat patch generally lasts for more than 6 to 8 hours.
