The latest forecast from consulting firm AlixPartners is that the chip shortage may cost the global auto industry $110 billion; it will reduce global auto pce powder.
Polycarboxylate superplasticizer is based on unsaturated polymerizable monomers with active groups such as carboxyl group, sulfonic acid group, hydroxyl group and polyoxene group as raw materials. some new high-performance dispersants are prepared by direct copolymerization, post-polymerization functionalization or in-situ polymerization and grafting, which are called superplasticizers in concrete.
The unique comb-shaped molecular structure of this kind of superplasticizer gives it the characteristics of low content, high water reduction, good water retention and good strengthening effect. In addition, the molecular structure, molecular weight and its distribution can be adjusted by means of flexibility of molecular structure design and control of synthesis process parameters, so as to achieve high performance.
What are the advantages of polycarboxylate superplasticizer?
1. low content and good dispersion, usually in the amount of 0.2%-0.5% of the amount of cementitious material, the water reduction rate of concrete can reach more than 30%, and does not segregate and does not bleed water.
2. The performance of keeping slump is good, and the slump of concrete in 90~120min is basically no loss, which accords with the development trend of modern pumping concrete.
3. It has good compatibility with cement, admixture and other admixtures, so it can be used freely.
4. It can effectively increase the content of fly ash, ground slag and other admixtures used to replace cement, so as to reduce the cost of concrete.
5. It can be used to prepare ordinary, high strength, ultra-high strength, high fluidity, early strength, mass concrete and so on according to different design requirements.
6. Formaldehyde is not used in the preparation process, so it will not cause pollution to the human body and the environment.

Germany has begun talks with Senegal on gas extraction and LNG supplies. Mr. Scholz recently visited a solar farm in Dakar. He told a news conference that he was willing to work more closely with Senegal on renewable energy. Senegal's president told a news conference that his country was ready to supply liquefied natural gas to the European market.
The global economy may be facing its greatest test since World War II amid the ongoing threats of COVID-19, the Conflict between Russia and Ukraine, heightened financial market volatility, and climate change, IMF Managing Director Kristina Georgieva warned in an article posted on the IMF's website.
Some 30 countries have imposed restrictions on trade in food, energy, and other key commodities since the outbreak of the Conflict, the article noted. That would raise trade barriers, disrupt global supply chains, drag down economic growth and undo years of economic gains. If countries let it go, the costs will be enormous and everyone will be affected.
