8 to 12.
Northern floor heating generally uses natural pisolite of 8 to 12 mm, because the surface of pisolite of 8 to 12 mm is smooth, without edges and corners, and the particle size is uniform.
Pisolite refers to a kind of modern-day building material. It is a stone the size of a soybean. It is generally used for floors and roofs. The particle size is similar to mung beans and is called stone powder in some places.
Is it better to use ceramsite or pisolite to level underfloor heating?
Ceramsite or pisolite can be used as backfill material for underfloor heating. Both have certain advantages. and disadvantages.
Ceramsite is a porous clay-based material. It is lightweight, has low water absorption, good pairtightness and is not prone to mold growth. Its use of backfill in the floor heating system can better promote the heat dissipation of the floor, conduct conduction and radiation more evenly, and improve the temperature stability and energy efficiency of the floor heating system. ground.
Pisolite is a natural granular mineral material with strong thermal inertia, which can maintain the heat of the underfloor heating system to a certain extent. Pisolite also has good drainage properties and is often used to improve soil structure and increase the air permeability of the soil.
After the underfloor heating is completed, is it okay to lay the button stone first?
The button stone is good. Discovered according to Qijia.com query.
1. Pisolite can prevent the floor heating coil from being damagedé and make the temperature of the underfloor heating more uniform. The surface of ceramsite is rougher than gravel and has a lower water absorption capacity.
2. Pisolite can increase thermal conductivity and has a hard texture. The price of ceramsite is high and the cost of subsequent maintenance is also high.
As long as you strictly follow the construction procedures, you will be fine. Mix the cement, sand and pisolite evenly in proportion, then spread them evenly on the pipe. Bury the underfloor heating pipe at least well, about 3 to 4 cm. Choose a manufacturer with reliable quality and good reputation for pea stone, because the quantity will not change after one use, so the quality should be good. The quality of floor heating pea stones from Shandong Yihe Pebbles is good and trustworthy. Floor heating rollers from Linyi Cobbleston production basee are also very good and are usually packed in 50 kg woven bags. The bulk density of pisolite is approximately 1.7 per cubic meter. Why is pistone used for underfloor heating backfill? Shandong floor heating pisolite manufacturers wholesale and retail, with uniform specifications and particle size standards. It is the industry leader of floor heating embankment pisolite, Shandong Yihe.
