The hollow board is a new type of material that is light, non-toxic, non-polluting, waterproof, shockproof, corrosion-resistant and colorful. The hollow board calcium plastic box assembled with it is very popular. So how to correctly install the hollow board calcium plastic box?

1. It is not suitable to use bitumen-containing PVC gaskets or tarpaulins, because their chemical additives will cause chemical corrosion of the hollow board, resulting in cracks or even cracks on the board surface.

2. If holes are drilled in the board, the spacing between the holes should not be too large or too small. If the distance is large, the accumulated thermal expansion length is large, and the reserved space is insufficient. If the distance is small, the movement of the plate will be severely restricted, resulting in excessive stress concentration. Some of the stress can be counteracted if it is allowed to bend outward during thermal expansion.

3. When installing screws or rivets through holes, the hole diameter of the hollow plate should be 50% larger than that of the bolts or rivets to avoid displacement of the plate during thermal expansion and contraction. Do not open the hole directly and fix the screw or rivet at the same time, so as not to leave room for thermal expansion and cold contraction.

4. Usually, it is suitable for drilling holes on the hollow board, the distance between the holes is 50cm, and the distance between the holes and the edge of the board is recommended to be more than 3~5cm.

5. The diameter of the rivet head should be 2 times the diameter of the handle, and a washer or wire should be added to avoid damage to the board due to local high pressure.

6. The screws should not be too tight, so as not to break the board. Once secured, allow the board to move a little bit.

7. During cold bending, do not use screws to fix the bent part. All holes should be filled with a neutral silicone structural sealant to prevent cleaning agents from penetrating the edges and affecting the use of the slab.

Instead of cartons, calcium plastic cartons are hollow board calcium plastic cartons. It not only inherits the advantages of folding, customizable, and low cost, but also has the advantages of waterproof, moisture-proof, wear-resistant, anti-warping, long life and so on. You are considering using a calcium plastic box. So what advantages does it have?

The biggest advantage of the hollow board calcium plastic box is that it is moisture-proof, not afraid of water, its toughness, good impact resistance, dust-free, no pollution, and can be recycled many times. In many regions, the real focus is on promotional packaged products. Now, some export vegetable makers and machinery parts makers are more optimistic about the product.

The hollow board calcium plastic box is a packaging material with high density polymer as the main raw material. It has the characteristics of beautiful appearance, good rigidity, no poison and no smell, light weight, heat preservation, sound insulation and moisture resistance. , High compressive strength, strong tear resistance, corrosion resistance, good feel. The length of the product is not limited and many colors are available. After inspection by relevant departments, the product performance indicators have reached the standards issued by the Ministry of Industry and Information Technology. It is an ideal crate packaging material, replacing wood with plastic and paper with plastic.
