What are the types of EPS pre-expander machines?

Generally speaking, there are two types of EPS pre-expander machine, which were continuous pre-expander machine and batch pre-expander machine. The main difference is that continuous EPS pre-expander machines expand polystyrene through continuous cycle operations and that batch EPS pre-expanders are performed in batches.

Why is the EPS foam article need adequate aging time?

Why is the EPS foam article need adequate aging time?

The surface of the EPS board product is wet from the machine, and the central temperature inside the product is about 90~105℃, and the inner part of the product also contains water vapor condensation water of 10~15% when the product is heated in a small amount, and the product quality can be ensured after the product is subjected to drying treatment. The expanded foam article should be placed in a greenhouse at a temperature of 60℃, maintained at a temperature of not less than 5d, or keeping the aging and airing time of 42d under natural conditions. Can also be stored in a greenhouse at a temperature of 60℃ for short time, and the two-knot and the aging method can be stored for a short time under natural conditions, so that the water can be gradually removed and the aim of stabilizing the product can be achieved in relatively short time aging.

What is EPS geofoam?

What is EPS geofoam?

Geofoam (GEOFOAM) is a foamed plastic product made of EPS as raw material. It has the characteristics of ultra-light weight, stable shape, elasticity, compression resistance, and low thermal conductivity. Under normal circumstances, EPS products have strong chemical stability, are insoluble in water, are not easy to age, are corrosion-resistant, resistant to microorganisms, and are not affected by climate change. They are used to prevent and control roadbed freezing damage, reduce roadbed settlement, and reduce lateral displacement of abutments. Plays an important role.
