Since 2022, Russia-Ukraine geopolitical conflicts have intensified, and global energy prices have risen sharply, with international natural gas prices hitting historic highs. As the most important transitional energy source in the transition from fossil energy to non-fossil energy, the share of natural gas in primary energy has increased from 14.6% in 1965 to 24.7% in 2020. The global gas price indices showed a unilateral downward trend from 2018, bottomed out in 2020, and remained low for a long time. However, since July 2020, the global gas prices have gradually fluctuated upward, and the impact of geopolitical events made the Dutch TTF gas price even hit record highs repeatedly.
An analyst of a securities company believes that the core catalyst of this round of global gas market lies in the lack of investment in upstream oil and gas resources caused by long-term low prices. Since 2020, although the epidemic has led to a decline in demand, the decline in supply has been faster, resulting in a large inventory consumption. In 2021, demand will recover faster than supply (the supply-side is less sensitive to prices, which will be reflected in investment).
As the world's two largest gas concrete foaming agent are also expected to change significantly.
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.
