As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.
For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.
Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the polycarboxylic acid superplasticizer in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the polycarboxylic acid superplasticizer.
In recent years, polycarboxylic acid superplasticizer has been widely used in many construction fields. Modern concrete has high requirements for additional functional additives, so polycarboxylic acid water-reducing agent in the concrete system, it should consider the following key technologies.
The compatibility technology of polycarboxylic acid series. Because of the special structure of polycarboxylic acid superplasticizer, it can not be stored and used with other superplasticizers, especially naphthalene superplasticizer. Need and different type of water reducing agent for alternate use, must be the relevant container for serious cleaning cleaning, prevent cross pollution to affect the quality of concrete. The adsorption performance of water reducing agent is not the same because of different types of cement, because the polycarboxylic acid water reducing agent is relatively narrow in the compatible range of cement, the incompatible situation is inevitable, so it is necessary to increase its dosage or use different types of cement to effectively solve this problem.
⑵ retarding technology of polycarboxylic acid water-reducing agent. In the construction process, due to the short retarding time, the use of retarding agent can effectively prolong the plasticity of concrete. However, the incompatibility of the two should also be considered to avoid the reduction of concrete performance.
⑶ Gas control. Polycarboxylic acid water reducing agent entrainment effect is very good, can be used together with defoaming agent, entrainment agent. The gas content of concrete can be controlled and its workability and durability can be improved by removing the concrete and then introducing it.
(4) Control of mud content in sand and stone. The application effect of polycarboxylic acid superplasticizer is also affected by the mud content of sand and stone. If the mud content in the sand exceeds 2%, the structures between the clay layers will therefore absorb large amounts of water reducing agent molecules, reducing the flow performance of the concrete. If the mud content is relatively large in the construction process, the anti-clay polycarboxylic acid water-reducing agent should be considered.

COVID-19 has led to many sites shutting down. What is the impact on China's foreign trade enterprises as a whole and small, medium and micro foreign trade enterprises?
. It is learned that some foreign trade enterprises have been affected by the epidemic and are facing periodic problems in production, operation, logistics and transportation. At the same time, problems such as rising raw material costs, slow cross-border transport and supply chain bottlenecks have not been fundamentally alleviated, and foreign trade enterprises, especially micro, small and medium-sized enterprises, are still facing considerable operating pressure. The price of polycarboxylic acid superplasticizer operated by foreign trade enterprises will also fluctuate with the changes of the epidemic.
