company news about Calcium zinc stabilizer in PVC processing problems encountered solutions

Calcium zinc stabilizer in the application of PVC processing often encounter narrow processing range (color, physical property change), the main reason is that the amount of sliding agent is insufficient to lead to yellow material, the amount of sliding agent is too large to lead to the decline of physical property of the product environmental protection calcium and zinc stabilizer its background color is not gray, at the same time some materials under a certain temperature and pressure easy to green powder after the material use time is short, The high temperature resistance of environmental protection calcium and zinc stabilizer produced directly on the machine without ripening is slightly poor.

Narrow processing range of solutions Narrow processing range (color, physical property change) improve the temperature resistance of the stabilizer, strengthen the initial coloring of the stabilizer to eliminate some materials that are easy to change color under high temperature conditions, adjust the lubrication system, ensure the appropriate shear control after the use of the material in strict accordance with the commissioning of the machine process parameters.
