Metal Pipes

Galvanized Pipe
Galvanized pipe was used several years ago for construction projects, but a large number of rust scales are produced in the pipe with time is used. The rust not only pollutes the sanitary ware, but also contains bacteria that grow on the galvanized pipe inner wall. The rust causes excessive heavy metal content in the water, which seriously endangers human health.

Copper Pipe
Copper pipe is corrosion-resistant and sterile, and it is the first-class product in plumbing pipes. The ways of copper pipe interface include clamp sleeve, welding and self-locking clamp spring, etc.
Copper pipes conduct heat quickly, so the hot water pipes produced by famous copper pipe manufacturers are covered with plastics and foaming agents to prevent heat emission. Another disadvantage of copper pipe is its high price. Welding construction costs are higher, and few households adopt welded copper pipes for decoration.
Stainless steel pipe
Stainless steel pipe is a kind of durable pipe material. But its price is high, and the construction technology requirements are relatively high, especially its material strength is relatively hard, so it is very difficult to process on site. Therefore, the probability of being selected in the decoration project is low.

Gas-forming admixtures is a kind of concrete admixtures which reacting in slurry, releasing gas and forming fine and uniform pore, this makes aerated concrete have porous structure.

Gas-Forming Admixtures Functions
The function of gas-forming admixtures in aerated concrete is to react in slurry, release gas and form fine and uniform pore, so that aerated concrete has porous structure.
The density of basic components of aerated concrete is generally about 1.8-3.1g/cm3, while the volume density of aerated concrete products is usually 500-700 kg/m3, or even lower. Therefore, aerated concrete must have larger porosity.
In general, the volume expansion of slurry is required to be nearly twice or more in the stage of slurry expansion. So it is required that the gas-forming admixtures can provide a large amount of gas which is insoluble or difficult to be soluted in water.
Make gases form spherical bubbles with appropriate size and uniform size in slurry, and keep them stable without deformation and fracture, it is very important to have appropriate foam stabilizer besides the slurry itself with certain temperature and consistency.
We call the material supplying the gas as the Gas-Forming Admixtures and the material stabilizing the bubbles as the Foam Stabilizer.

Gas-Forming Admixtures Types
There are many kinds of Gas-Forming Admixtures, which can be divided into metal and non-metal.
Metal admixtures include aluminium-zinc and magnesium powder or paste, aluminium-zinc alloy and ferrosilicon alloy, etc; Non-metallic materials include hydrogen peroxide and calcium carbide.
