Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many foaming machine ,cement foaming machine.
Cement foaming machine needs auxiliary test machine to help achieve better foaming effect in construction application. Cement foaming agent is a chemical admixture, which is added to cement. Compensate for shrinkage and tension of steel bars to produce prestress and to fully fill cement gaps.
According to the construction requirements and the quality requirements for foamed cement, we believe that the following requirements are put forward for the foaming agent:
1. The amount of foaming, the actual amount of foaming is not only a physical indicator, but also a cost indicator, if the amount of foaming is smaller, but the price is lower.
2. Foam strength is a comprehensive index of the collapse degree, shrinkage degree and foam stabilization time of foamed cement products.
3. Foam pore size and uniformity: The foam pore size and uniformity are the reliable guarantee for the strength index and thermal insulation index of the finished product. Only products with ideal pore size can be regarded as good products.
4. The purity of the foaming agent and the cleanliness of the foaming agent play a suitable and protective role for more and more sophisticated equipment. Large-scale continuous operation equipment should minimize the failure rate in its operation during operation, otherwise, It will seriously affect the quality of the project and the progress of the project. At the same time, too many impurities will affect the hydration reaction of the cement itself, resulting in a decrease in quality.
5. Non-corrosive, requires foaming agent, no corrosive pollution to the equipment environment, and has environmental protection performance.
6. Persistence of foam: This indicator has been highly demanded by people in the past. Some people pursue the longer the duration of the foam, the better. In fact, it is not necessary to pursue too long a stable foam time. We believe that the foam emitted by the foaming agent is Within the scope of application, its duration only needs to exceed the initial setting period of the cement product, because the existence of foam is meaningless when the product enters the initial setting period, and the ideal stabilization time exceeds 24 hours, which can meet various construction requirements.

Due to the limited total amount of traditional energy, people have a huge demand for cleaner and greener new energy alternatives. Now, the emergence of graphene is unlocking the possibility of its application in the energy field, which can create a greener, more efficient, and sustainable future. Here Francesco Bonaccorso, Deputy Director of Innovation at the Graphene Flagship Program, explains how his researchers have developed a series of initiatives to bring graphene from the lab to the commercial market. Graphene has become a research hotspot for new materials in the 21st century. Graphene has been adopted by many industries, the most notable of which are healthcare and key material applications.
The development of graphene has brought huge fluctuations in the demand for foaming machine ,cement foaming machine, and the demand for foaming machine ,cement foaming machine will continue to grow in the future. You can contact us for the latest news on foaming machine ,cement foaming machine.
