When it comes to the extruding board, we should be familiar with it, but due to the increase in its demand, it has led to the occurrence of some chaos, and the products on the market are also of various kinds. So what are some ways to help us choose it?
The extruder is made of polystyrene resin. But much of the market today is made from recycled materials. Very few are produced by formal manufacturers. From the raw materials to see the advantages and disadvantages of the squeeze molding board: Baijing; Blue extruded board & GT; Black extruding board. There are also red and yellow extrusions on the market that are generally similar to blue extrusions.
Look at the microstructure.
One of its main uses is as a geothermal layer. The secret of its insulation lies in its continuous uniform surface and closed Honeycomb structure. The more uniform the bubble hole, the better. The three microscopic structures are white crystal plate, blue plate and Blackboard. The bubble holes of the White crystal plate are uniform and closed. Blue plate bubble hole closed well. There is no bubble hole in the blackboard.
Look at the direct pressure effect
Baijingban can not be seen by the naked eye after pressing. The good blue plate has a smaller print. The sag of the poor blue plate is obvious. The blackboard was severely damaged.
Look at life span.
The life span of a house is generally more than 50 years. Ground heating as a hidden project of the house, if it can not live with the house, it means that it will be reinstalled during use. The experiment shows that the service life of white crystal plate can reach 50 years. A good blue board can have a service life of 30 years, and a poor blue board can generally be used for 15 years. The useful life of the blackboard is generally 5 years.
Look at environmental protection.
It is recommended not to use flame retardant panels for home wear because the flame retardant HBCDD is not environmentally friendly. Baijingban is 100 % new material for environmental protection. Blue plates have certain additives. The blackboard is made of all recycled materials. Environmental protection white crystal plate & GT; Blue board & GT; The blackboard.
Look at the weight
Capacity is an important indicator of it. Directly linked to compressive performance. The capacity of the ground heating board is 35 to 36 KG/m <UNK>. The weight of a good blue plate is also the same value. However, due to the problem of blue plate raw materials, even if the capacity is the same, the quality of the White crystal plate is still better than the blue plate. The nearly blue plate has a capacity of about 30KG/m <UNK>. The capacity of the blackboard is generally around 25KG/m <UNK>.
