company news about Twice the result with half the effort - calcium and zinc stabilizer use skills

As the national environmental protection requirements, calcium zinc stabilizer has gradually replaced lead salt stabilizer, widely used in sheet, pipe, corrugated pipe, profiles, pipe fittings and PVC products such as wire and cable production and processing, while calcium zinc stabilizer, high ratio of environmental protection, but we are in the process of using or to master some skills, can have twice the result with half the effort.

1. Confirm the green environmental protection of calcium and zinc stabilizer formula: it is necessary to pay attention to whether the content of heavy metals (lead, cadmium, tin, barium) can meet the requirements of the product and meet the requirements of the new national standards.

2, calcium zinc stabilizer lubrication is strong, to add more external lubricant.

3. The thermal stability of calcium and zinc stabilizer is weaker than that of lead salt, and the processing window is narrower and the control requirements are higher.

4, the operation process pay attention to the mold clearing cycle, calcium and zinc stabilizer lubricant added more, easy to lead to the increase of precipitation, thus affecting the mold clearing cycle. For large-scale production has a greater impact, we should strictly select the stabilizer variety. If it is its own stabilizer, it is necessary to cooperate with PE wax or oxidized wax with good lubrication effect in the middle and late period. Also strictly control the vacuum degree, can reduce precipitation, prolong the time of cleaning mold.

5, good stabilizer formula and appropriate dosage of the product appearance, material properties, aging resistance and so on have little influence.
