Teach you how to see the quality of the extruded board

1. Look at the raw materials

Sintra Boards Manufacturers extruded boards are produced from polystyrene resin. But many extruded boards on the market today are made from recycled materials. Few are produced from BASF crystals. From the perspective of raw materials, the pros and cons of the extruded board are: white crystal extruded board > blue extruded board > black extruded board. There are also red and yellow extruded boards on the market, which are generally similar to blue extruded boards. The following three are BASF crystal, recycled polystyrene, and recycled polystyrene.

2. Look at the microstructure

One of the main uses of extruded polystyrene is as a floor heating insulation layer. The secret of extruded board insulation lies in its continuous uniform surface and closed-cell honeycomb structure. The more uniform the cells, the better. The following three microstructures are white crystal plate, blue plate and black plate. The cells of the white crystal plate are uniform and closed. The blue plate cells are well sealed. The blackboard has no bubbles and is basically not closed.

3. Look at the effect of pressing the hand straight

The following figure visually shows the effect of different extruded plastic boards after the fingers are pressed. The white crystal plate is basically invisible to the naked eye after being pressed. Good blue boards have smaller prints. The depression of the poor blue board is obvious. The blackboard is directly damaged *severely.

Fourth, look at the service life

The lifespan of a house is generally more than 50 years. As a hidden project of the house, if the floor heating cannot have the same life as the house, it means that it will be reinstalled during use. Tests have shown that the service life of the white crystal board can reach 50 years. The service life of a good blue board can reach 30 years, and a poor blue board can generally be used for 15 years. The service life of the blackboard is generally 5 years.

Five, look at environmental protection

Jiangyin Jiuchen Building Materials Co., Ltd. recommends not to use flame retardant boards for home improvement extruded boards, because the flame retardant HBCD (HBCDD) is not environmentally friendly. The white crystal board is made of 100% new material and is environmentally friendly. The blue board has certain additives. The blackboard is made of recycled materials. Environmentally friendly white crystal board>blue board>blackboard.

Sixth, look at energy saving

It can be seen from the floor heating structure diagram that the less the heat dissipation of the floor heating, the more energy-saving it is. Because of the bubbles, the energy saving of the three: white crystal board > blue board > black board.

Seven, look at the weight

Bulk density is an important indicator of extruded sheets from Wholesale PVC Sheets Manufacturers. It is directly linked to the compressive performance. The bulk density of white crystal panels for floor heating is 35 to 36KG/m³. The bulk density of a good blue board is also this value. However, due to the problem of the raw materials of the blue board, even if the bulk density is the same, the quality of the white crystal board is still better than that of the blue board. The bulk density of the almost blue board is about 30KG/m³. The bulk density of the blackboard is generally around 25KG/m³.
