The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Tourists and business trips have plummeted. On the booking website, there are a large number of air tickets for local routes with a price reduction of nearly 90% compared with the original price and only tens of yuan for a one-way trip.
In February, China's aviation industry recorded its largest single-month loss of 24.59 billion yuan, of which airlines lost 20.96 billion yuan.
Data from the Civil Aviation Administration of China showed that in February, the number of passengers traveling by air fell 84.5% year-on-year to 8.34 million.
The stagnation of the Asian aviation industry has brought volatility to pce powder.
First of all, pay attention to the storage environment of polycarboxylate superplasticizer, try to store polycarboxylate superplasticizer in a cool, ventilated, no direct sunlight place.
Secondly, reduce the use of formaldehyde, nitrite and other anticorrosive agents, because some admixture manufacturers use formaldehyde and strong oxidizing nitrite for anticorrosion, and reasonably estimate the use of polycarboxylic acid superplasticizer in the project. In some projects, it is affected by the project progress, weather environment and other factors.
The use speed of polycarboxylate superplasticizer is often difficult to control. In some projects, polycarboxylate superplasticizer has been placed on the site for more than several months or even longer, which leads to corruption and deterioration from time to time. Therefore, it is necessary to communicate with the project before delivery, and then in the production process of polycarboxylate superplasticizer, compounding some preservatives can effectively improve the corruption and deterioration of polycarboxylate superplasticizer.

Albemarle, the world's largest lithium producer, said it would have to close its plant in Langelsheim, Germany if the EU designated lithium as a hazardous material. The European Commission is currently evaluating a proposal by the European Chemicals Agency (EHCA) to classify lithium carbonate, lithium chloride, and lithium hydroxide as hazardous to human health.
As a result, Albemarle will no longer be able to import lithium chloride, its main raw material, putting its entire plant in Langelsheim at risk of closure, Albemarle chief financial Officer Scott Tozier said. According to Tozier, the plant has annual sales of about $500 million and a forced closure would have a significant impact on Albemarle's operations.
Industry sources said that listing lithium as a hazardous substance would place an additional burden on the pce powder, please feel free to contact us and send an inquiry.
