What are the criteria for judging the quality of accordion protective covers?

The difference between the quality of accordion-type protective covers is mainly: the quality of raw materials. The raw materials of accordion-type protective covers are divided into three-proof cloth, hanging tape, silk cloth, etc., and the supporting materials are divided into: barley paper, PVC, etc. The quality of these materials is mainly determined by the thickness, glossiness and tensile strength of the materials.
The qualified rate of products, the accordion-type protective cover products mainly depend on whether the size is appropriate, whether the stretching length is sufficient, whether the compression exceeds, etc. Flexible accordion-type protective cover Flexible accordion-type protective cover is a product series that can be combined arbitrarily. Its raw materials, appearance, processing methods and size can be determined according to actual conditions.

A simple way to judge the quality of protective covers and protective covers by appearance and appearance.
1. Smell: If there is a pungent smell, the coating material must be poor, not wear-resistant, and easy to age.
2. Surface texture: The cloth texture is vague or unclear, the price is low, the coating material must be poor, not wear-resistant, and easy to age.
3. Tensile load: Professional tensile test equipment is required for detection.
4. Tear load: Professional tensile test equipment is required for detection; manual tearing observation of the tearing mouth can only judge the quality of the coating material. The tearing mouth is uneven, the surrounding wrinkles are severe, and the yarn (except industrial yarn) is exposed in different lengths, indicating that the coating and yarn have poor adhesion, and the coating material must be poor, not wear-resistant, and easy to age.
All flexible accordion-type protective covers can be used horizontally, vertically or horizontally to ensure smooth and noiseless operation. By using raw materials with small thickness, it can be compressed to meet the requirements of the narrow working space of modern machinery.
