1000 degree high temperature baking 4 hours without deformation of the material

Build a house with bricks? You OUT. Recently, a brand new wall building material has been produced in Longkou and produced in batches. It recycles and uses polystyrene as raw material. Compared with traditional wall building materials, it does not waste land resources due to soil borrowing.

Polystyrene is a colorless, transparent thermoplastic that has a glass transition temperature of more than 100 degrees Celsius, and is therefore often used to make various disposable containers that need to withstand boiling water temperatures, as well as disposable foaming lunch boxes, etc. .

The new wall building material is made of polystyrene particles, ordinary portland cement, polymer additives and water and other raw materials through stirring, pressure, vibration molding, made of horizontal and vertical holes with the plate member.

"It weighs only 1/2 to 1/3 of the weight of concrete components of the same volume, but it is superior in heat insulation, sound insulation and fire resistance." The researchers told reporters that they used 1080 °C flame to continuously grill new building materials 4 Hours or more, the wall remains intact.

As a building material, bearing capacity and earthquake resistance are of course the primary criteria. In the experiment, the basic crack resistance of this new type material can reach 8 degrees, which is indestructible.

What is particularly commendable is its green and environmentally friendly features. Due to the recycling of polystyrene (such as common foaming lunch boxes) as raw materials, the “white pollution” has been greatly reduced and a circular economy has been realized. In addition, there is no dust and harmful gases in the production process, and corner scrap can be recycled. Calculated at an annual output of 960,000 cubic meters, the annual savings of 500 acres of land, 14,000 tons of standard coal, 36,000 tons of carbon dioxide emission reduction, emission reduction dioxide * 360 tons.

"The wall built with it is not moldy, leaky, crack-free, or bug-free. It has the characteristics of low construction cost and fast construction speed." Scientists and technicians said that this new type of building materials can be widely used in the construction of residential buildings. Apartments, villas, schools, office buildings, commercial buildings, stadiums, theaters, highway and railway noise walls, frame buildings and industrial plants, etc., have broad prospects for promotion.
