How to Effectively Distinguish Between Hollow Plastic Template Doped with Old Raw Materials?

Mar. 14, 2020

Building plastic formwork is no longer a new product today. After so many generations of changes, building plastic formwork is already a mature and fully in line with national policies. However, the raw materials of building plastic formwork are different, and the production process of some enterprises is not up to standard, resulting in different quality of formwork. Today, Formwork Tie Rod supplier will share with you three effective ways to distinguish architectural plastic formwork doped with old materials.

1. The vertical ribs of the hollow plastic building formwork are thick and straight, and the quality of the building plastic formwork with thin vertical ribs and bends is not good because the production process is up to standard and produced with new materials.

2. More and more manufacturers choose to co-extrude the UV layer of the hollow plate. At present, many manufacturers claim that their products have been extruded with a UV layer, and in fact, the ability of the anti-fog layer to recognize UV rays is a key factor causing panel aging. But whether the ultraviolet layer can really play a role remains to be further studied. Good building plastic template UV layer can be measured not only by thickness, but also by its uniform co-extrusion level, the thickness of the UV layer and the uniformity of the hollow template. For the market, some UV data were not added at some bottoms, but were incorrectly filled and co-extruded with the UV layer hollow sheet.

3. If there are black spots and crystal points on Plastic Formwork, it means that they contain a lot of impurities. The more impurities, the older the material. Good architectural plastic formwork must be clean and transparent. The quality of materials can also be distinguished by studying the fluidity of the hollow plate melt. Due to the long molecular chain of carbonate resin, repeated high temperature melting will destroy its molecular structure and change from large molecules to small molecules.

The old material should melt from the beginning and its molecular chains will break and then flow. Therefore, in theory, the better the fluidity of the data in the molten state, the worse the quality of the product. Although the method is simple and easy to understand in theory, it is still difficult to operate in reality. Users without test conditions can send building plastic formwork materials to professional institutions for inspection. Everything has two sides. The production of building plastic formwork with old materials does not necessarily mean that it will be of poor quality. If the impurities are removed properly and the production process is advanced, even the quality of building plastic formwork produced with old materials is not worse than that of new raw materials. Even the quality of products produced by new materials is better than some manufacturers with poor production processes.

Regardless of the new and old formwork materials, good quality is the last word. I hope that everyone must choose a regular manufacturer when purchasing construction plastic formwork. Only formal plastic formwork manufacturers can ensure quality.
