How can cement foaming machine achieve better foaming effect in construction
A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including 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.

Greece will hand over Iranian oil it intercepted from a Russian-flagged tanker to the United States at the request of the U.S. Justice Department, Greek port police said recently, AFP reported. The decision angered Tehran.
In April, Greek authorities reportedly seized a Russian oil tanker, the Pegas, which was said to be heading to the Turkish port of Marmara.
Reports say the ship was docked in Calistos Bay with a crew of several people said to be Russian. The Greek coast guard said the ship had been renamed the Lana.
The report notes that the European Union imposed sanctions on Russia after the conflict broke out in February. Greek authorities seized the tanker in accordance with European Union sanctions.
According to information at the time, the tanker was carrying 115,000 tons of Iranian oil.
Iran's Ports and Maritime Organization strongly protested Greece's decision, calling it an "international bandit." "The Islamic Republic of Iran will not give up its legitimate rights and expects the Greek government to abide by its international obligations in the area of navigation and shipping," it said in a statement on its website.
Iran's Foreign Ministry, through the International Maritime Organization, called on the Greek government to release the tanker and its crew overnight, adding that "the Americans discharged their cargo," the report said.
Athens did not immediately respond to the Iranian protest and gave no further details about the oil on board or how it was handed over to the United States, the report said.
The foaming machine ,cement foaming machine price is expected to increase in the next few days affected by the change in supply and demand markets.
