Magnesium oxide powder has the function of plasticizing rubber

Magnesium oxide can play a stable role in mixing, can prevent burning in processing, and improve the burning of rubber in the storage process, and in plasticizing, but also has the role of plasticizing rubber.

Adding magnesium oxide to rubber at the beginning of mixing can prevent early crosslinking and cyclization of neoprene rubber, and can increase the safety of operation. In curing time and into curing agent, play the role of hydrogen chloride acceptor, prevent hydrogen chloride on fiber tissue erosion. Magnesium oxide can improve heat and aging resistance. The quality of magnesium oxide has great influence on the processing and vulcanization of neoprene adhesive. When the dosage of magnesium oxide is increased to 10 parts, the colloid can have higher plasticity and better storage stability.

Zinc oxide mainly do vulcanizing glue, can make vulcanizing flat. Increasing the amount of zinc oxide can improve the heat resistance and aging resistance, but the glue is easy to burn and reduce the storage stability of the glue. Large amounts of use can also make the rubber material hard and lose plasticity. But it can increase the curing speed, curing degree and high temperature resistance. General magnesium oxide and zinc oxide used at the same time so as to solve the vulcanizate easy to burn shape and high degree of vulcanization and curing speed, cutting crosslinking degree than single use much higher.

Magnesium carbonate as a high technical content of precision chemical products, from the product research and development, production process selection, raw materials and additives solvent selection, production process control and so on all need professional knowledge and rich experience. Moreover, there are many downstream application industries of magnesium carbonate, and various industries have different requirements for magnesium carbonate, resulting in a wide range of magnesium carbonate products, and the performance between various classes are not the same, which also puts forward high requirements for the product research and development and technical management strength of enterprises. Therefore, magnesium carbonate industry has higher technical barriers.

Although magnesium carbonate products are added to the downstream customer products in small amounts, but has an important impact on the performance and quality of their products. Therefore, the downstream customers have higher requirements for the quality of magnesium carbonate products and the stability of supply. In order to maintain the stability of product quality, the downstream customers of magnesium carbonate are very careful in the selection of each kind of magnesium carbonate affecting the coloring performance of the product, which often needs to go through a long time and strict test verification. In order to ensure the stability and sufficiency of supply, downstream customers often have to consider whether the supplier has the corresponding production, supporting capacity and growth, and put forward higher requirements for magnesium carbonate production enterprises. And once the downstream customers have the trust of magnesium carbonate products and magnesium carbonate production enterprises, the loyalty will be relatively high. Due to the lack of stable product quality verification, it is difficult for new entrants to gain customers' trust and orders in a short time, so there are high brand and customer perception barriers in magnesium carbonate industry
