The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on Cement Foaming Agent.
Cement foaming agent is the core material of foamed concrete. Choosing a suitable cement foaming agent is the key to producing qualified products.
1. Fully understand the type of cement foaming agent
Different types of foaming agents have different foaming power and foam stability, so there are certain limitations in the use process. Only after knowing the type of foaming agent can you understand its performance characteristics. When choosing a foaming agent, you can have a target.
2. Carefully master the technical indicators of foaming agents
The main indicators to measure the quality of foaming agents include foaming power, foam toughness, and bleeding volume. The foaming power reflects the foaming ability of the foaming liquid, which can be expressed by the foaming height and the foaming multiple. The higher the foaming height and the larger the foaming multiple, the stronger the foaming power of the foaming agent.
3. Carefully understand the use of foaming agent
The foaming agent on the market generally has a relatively high concentration, and when used, it needs to be diluted with a certain proportion of water to form a foaming liquid, and then the foaming liquid is foamed. The concentration of the foaming liquid is closely related to the foaming effect. Too high or too low a concentration will affect the foaming effect. Only with a suitable concentration can a high foaming ratio and high-quality foam be obtained.
Foaming agent production characteristics
1. The foaming speed should be appropriate, too fast or too slow will affect the quality of concrete.
2. The diameter of the generated hydrogen bubbles should be small and evenly dispersed. Especially when the cement slurry is poured into the injection mold under the full volume state, it needs to be evenly dispersed to ensure the quality of the injection mold.
3. The setting and solidification of cement shall not be affected when gas is generated. If the setting of cement is delayed, the strength of the cement will decrease or abnormal cement setting will occur.

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 Cement Foaming Agent operated by foreign trade enterprises will also fluctuate with the changes of the epidemic. Contact us for the latest quotation on Cement Foaming Agent.
