What are the performance characteristics of seafood foam boxes?

When using seafood foam boxes, do we usually know their performance? Here we can introduce some relevant content. This is a product frequently used in our lives. We need to pay attention when using it. Below, we will introduce it to you.  

The main raw material of seafood foam boxes is seafood foam boxes, also known as polystyrene, the main difference being density. Pure polystyrene foam board is non-toxic, but polystyrene foam board needs to add plastic additives to improve some of its properties.

Depending on the foaming method, the processing methods can be divided into molding and extrusion methods. This uniform and closed cavity structure makes seafood foam boxes have the characteristics of low water absorption, good insulation performance, light weight, and high mechanical strength. The density of seafood foam boxes is determined by the expansion ratio of polystyrene particles during the molding stage, generally between 10~45㎏/m3, and the apparent density of seafood foam boxes used in engineering is generally 15~30㎏/m3. In road engineering, the density of lightweight filler seafood foam boxes is 20㎏/m3, which is 1%~2% of ordinary pavement fillers. Density is an important indicator of seafood foam boxes, and its mechanical properties are almost proportional to density.

Seafood foam boxes have strong independence, which is very beneficial to the stability of high slopes. According to the Swedish bridge design code, the active lateral pressure coefficient is 0, and the static lateral pressure coefficient is 0.4, so there is no need to calculate the passive lateral pressure. Because the lateral pressure generated by seafood foam boxes after vertical compression is small, using seafood foam boxes as subgrade fill in the bridge head section can greatly reduce the earth pressure behind the abutment, which is very beneficial to the stability of the abutment.

The friction coefficient f between seafood foam box blocks and sand is 0.58 (dense)~0.46 (loose) for dry sand and 0.52 (dense)~0.25 (loose) for wet sand. The F value between seafood foam box blocks is between 0.6 and 0.7. Density is a characteristic that directly determines the weight of the packaging. According to product requirements, low-density packaging is more popular in most cases because it can reduce the types of packaging, reduce raw material consumption, and lower transportation and costs. The development needs of the modern logistics industry are gradually diversifying, and packaging materials with shock resistance are becoming increasingly popular. Seafood foam boxes are one such material, with good impact absorption performance, so they can protect items well. This is the performance of mechanical properties, with such good compressive strength and resilience, its performance has many levels, and we can choose packaging according to the weight of the items.
