He believes that the graphene market in China, from a business perspective, is not "hot enough" to "reduce" the fever, and should remain "hot". It is an allotrope in which a single layer (atoms) of carbon forms a hexagonal, two-dimensional grid in…
In the process of concrete mixing, the mixing method of admixture has a great influence on the effect of admixture.…
Admixtures can be used for almost all kinds of concrete, but suitable admixtures must be selected according to engineering needs, construction conditions and construction technology.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
The purity of carbonaceous raw materials such as petroleum coke and pitch coke is relatively high, and the ash content is usually less than 0.5%, while the purity of natural graphite treated by flotation is relatively low, and the carbon content is u…
As chemical raw materials have risen in a row for nine consecutive years, should coating companies increase their prices? Starting from the beginning of 2020, chemical raw materials have entered a period of rising prices, and by 2021, prices have inc…
While the US presents itself as an advocate of expanding vaccine supplies, the world is rapidly becoming more dependent on China for vaccines as the COVID-19 pandemic makes it difficult for India to fulfill its vaccine supply agreement. "Not onl...…
