The pea stone is smooth and will not damage the floor heating pipe, but the price is relatively high.
1. The smooth button stone will not damage the floor heating pipe, but the price is relatively high. Pisolite concrete uses pisolite as underfloor heating backfill to protect underfloor heating coils. The natural silicon content of pisolite gives underfloor heating better thermal conductivity. The price of floor heating leveling is as low as 50-80 yuan/㎡, while the most expensive price is 100 yuan/㎡ or even more.
2. Melon seed slices are cheap, but their irregular shape and sharp edges will scratch the heating pipes during the construction of the underfloor heating embankment and during their subsequent use. Over time, there will be hidden dangers of water leakage.
Which ceramsite pea stone is bestlure for underfloor heating backfill
Melon seed slices: Melon seed slices are cheap, but their irregular shape and sharp edges can cause damage during and after floor heating. floor. embankment construction. If the heating pipe becomes scratched during use, there may be a risk of water leaking over time.
Pisolite: A stone similar to the size of a bean, it is therefore called button stone. is rounder than melon seed slices and will not scratch the heating pipe, is an ideal filler material, its thermal conductivity is stronger than melon seed slices, use better materials
Where can I buy Hefei underfloor heating leveling knobs?
The backfill material for underfloor heating can be ceramsite or pisolite, both of which have certain advantages and disadvantagess.
Ceramsite is a porous clay-based material. It is lightweight, has low water absorption, good air permeability, 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 uniformly, and improve the temperature stability and energy efficiency of the heating system. by the 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.
The density of concrete is approximately 1.8 tonnes/cubic meter. 600×3×0.1×1.8=324 tons. The density of concrete withdifferent sands and gravels and different proportions is slightly different.
When leveling for underfloor heating, attention should be paid to the proportion of sand, cement and pisolite. Although pisolite is good, the quantity should not be too large (usually 2 square meters per pack for leveling, 30 kg). per package). If there is too much pisolite, it will affect the leveling process. The amount of sand and cement used, and sometimes the sand on the ground, is also linked to this! the price of pisolite is about 8-10 times that of melon seed slices. The diameter of the pisolite is preferably 10 to 12 mm.
