The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on sodium silicate.
Soaps and detergent
Sodium silicate has the ability to enhance surface effects, such as wetting with organic surfactants (reducing surface tension), helping to keep small dirt or oil particles suspended in the detergent, or enhancing the ability to remove dirt from the surface.
The alkalinity of sodium silicate enables it to neutralize acidic soil and promote the emulsification of oil and the dispersion of protein.
Sodium silicate as a cardboard coating can increase the hardness of the cardboard and increase its resistance to moisture, fire, grease and pests. Silicate can also be used as an oil repellent alone.
Sodium silicate can be used as a primer for the application of auxiliary materials such as paraffin, naphthalene chloride, wax, gum, nitrocellulose, varnish and other cardboard coatings. It fills the pores of the cardboard and reduces the water absorption of the paper, thus reducing the amount of topcoat required.
Soluble silicate can be used as cement binder. When Portland is combined with cement components, they will undergo chemical reactions to form substances with strong bonding properties. It can also be used to improve the durability of concrete.
Soluble silicate is used in many mineral enrichment processes. The main use of sodium silicate in ore flotation is as an antiflocculant to disperse unwanted siliceous substances. Only a small amount of silicate with a concentration similar to that used in cleaning operations is required. The ability of silicate to form a sodium ion layer on the particle surface is important for preparing the surface for specific separation. Sodium silicate helps to prevent corrosion, thereby reducing ball wear in the mill.
Dilute anionic silica aqueous solution provided by soluble silicate can inhibit the corrosion of metal surface.
As an additive in water, dissolved SiO2 can prevent corrosion of metal storage tanks and distribution lines. It reduces corrosion of pumps and pipelines by acidic water (for example, from mine drainage); reduces corrosion during ball rod mill grinding; and minimizes corrosion of process equipment as an ingredient in spray drying, agglomeration or dry mixed detergent formulations; and metal parts in laundry and dishwashing equipment. As a component of the liquid in the ‘permanent’ automobile cooling system. As an additive for water treatment compounds in boilers and cooling towers.
