U.S. refiners forecast strong first-quarter earnings as margins on gasoline and diesel sales improved, refining capacity fell sharply and crude supplies tightened due to the Russia-Ukraine war.
Global refining capacity has declined amid the coronavirus pandemic, with several less profitable refineries closing in the past two years. However, global fuel demand has rebounded to near pre-pandemic levels, boosting the profits of facilities still operating.
Seven U.S. independent refiners are expected to earn 61 cents a share, compared with a loss of $1.32 in the first quarter of 2021, according to Refinitiv's IBES.
By 2022, gasoline and distillate 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.
