The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete foaming agent?
Foam cement is a new type of lightweight thermal insulation material containing a large number of closed pores. It is to use mechanical method first to concrete foaming agent full foam, and then foam and cement mud even mixing, cast-in-place construction, or through the pumping system of foaming machine molding and become. Finally, after natural conservation, formed.
It belongs to a kind of bubble insulation material. Its outstanding feature is the closed foam hole inside the concrete can make the concrete lightweight, heat preservation, and heat insulation.
Foam Cement Construction Process
Feed the concrete foaming agent into the air compressor to produce foam with a certain tension. Then mix the foam and cement slurry, during this process cement will continue to expand. When the expansion effect reaches the preset ratio the foam cement can be produced.
Usually, the foam cement is used in the field of the ground heating insulation layer, roof insulation layer, and frame structure of the wall filling layer.
For cement, people generally use 32.5R ordinary Portland cement. For the foaming agent, the animal foaming agent is recommended for the insulation industry.
Because in terms of the performance, animal foaming agents can produce independent pores, and the product has high strength. The produced foam cement has light bulk density, uniform distribution of pores, good thermal insulation, permeability, and good sound insulation. Due to the characteristics of continuous bubbles, compared with animal foaming agents, vegetable foaming agents can make foam cement with higher bulk density and poor thermal insulation, and it is inferior to animal foaming agents in impermeability and sound insulation. However, the vegetable foaming agent has the advantages of a large foaming amount and good fluidity and is easier to operate than animal foaming agents in floor heating construction.
It is suggested that foaming agent manufacturers produce foaming agents with different characteristics according to construction needs. For example, for constructing the inclined roof, the pure animal foaming agent is recommended, because its fluidity is poor, and strength is good. For flat roofing and the floor heating construction, the mixed foaming agent is recommended. Because the mixed foaming agent is added a certain botanical composition on the basis of the animal foaming agent, so that the foam multiples, the liquidity increases, and it is easy to level, making it suitable for floor heating construction.
