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 superplasticizer.
Description of Polycarboxylate Superplasticizer
Polycarboxylate superplasticizer is a kind of powdery polycarboxylate high performance superplasticizer made by a new process. It has excellent comprehensive index, good dispersibility, high water reduction rate, good adaptability to various cements, and no pollution in green.
Since polycarboxylate superplasticizer is mostly in liquid state, due to the improvement of technology recently, the milling process has been improved, and polycarboxylate superplasticizerpowder has become more common. In contrast, polycarboxylate superplasticizer in powder state provide a lot of convenience from transportation to customer use, and powder polycarboxylate superplasticizer have become the development trend of such products.
polycarboxylate superplasticizer breaks the routine in production process, adopts thermal synthesis process, does not add isolation agent, and produces products with higher purity. In terms of product performance, high-purity polycarboxylate superplasticizer powder have the characteristics of less dosage, high effective components and good slump retention performance, which further reduces customer costs.

Usage method of polycarboxylate superplasticizer powder
1. According to the concrete design requirements, adjust the water consumption or sand rate through experiments to reach the dosage of water reducer whose slump, strength and setting meet the requirements.
2. Polycarboxylate superplasticizer powder is applicable to high-performance concrete, high-strength concrete and large flow concrete. For concrete higher than C50, raw materials shall be selected according to relevant technical specifications, appropriate mixing process shall be determined, and a certain amount of experimental data shall be obtained. Make the flow performance of the produced concrete meet the construction requirements, and the concrete strength should have a certain surplus coefficient.
3. Polycarboxylate superplasticizer powder can be mixed with mixing water into concrete at the same time, and the effect of mixing water into concrete is better.
Safety and precautions of Polycarboxylate Superplasticizer Powder
1. Polycarboxylate superplasticizer powder is a weakly alkaline solid, non-toxic, non corrosive and non polluting to the environment. However, it is not edible. When it comes into contact with human body and eyes, it should be washed with clean water as soon as possible. If it causes allergy to some human bodies, it should be treated in time.
2. Polycarboxylate superplasticizer powder should be stored in a cardboard bucket lined with plastic bags to avoid the mixing of rain water and sundries.
3. The shelf life of polycarboxylate superplasticizer powder is 12 months.
Packaging and storage of polycarboxylate superplasticizer Powder
Paper plastic composite packaging lined with plastic bags
Packaging: 20kg/bag

Polycarboxylic acid superplasticizers are used as high range superplasticizers in high performance concrete, high strength concrete, high fly ash/slag concrete, cement grouting and dry mortar. Appearance:Off-white powder Water content:3.6% pH:8 Total alkali:5.8% Gas content:3.1%For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical superplasticizer for the time being, but the market demand for superplasticizer in the future will also change with the influence of various external factors.
