When Magnesium Oxide is mixed, it will play a stabilizing role in the mixing process, which can prevent coke from burning and improve the scorching of the compound during storage, and also play the role of plasticized rubber when it is being plasticized.
The addition of Magnesium Oxide to the rubber at the beginning of mixing can prevent the early crosslinking and cyclization of the chloroprene rubber, and can increase the safety of the operation. At the time of vulcanization, it becomes a vulcanizing agent, which acts as a hydrogen chloride receptor to prevent the corrosion of hydrogen chloride on fibrous tissue. Magnesium Oxide can improve the heat-resistant and aging resistance. The quality of Magnesium Oxide has a great influence on the processing and vulcanization of chloroprene rubber. When the amount of Magnesium Oxide is increased to 10, it can make the colloid high plasticity and better storage stability.
Zinc Oxide is mainly made of vulcanizate, which can make the vulcanization flat. Increasing the amount of Zinc Oxide, although it can improve the heat-resistant and aging resistance, but the adhesive is easy to burn and reduce the storage stability of the rubber. A large amount of use can also make the rubber hard and lose its plasticity. But it can increase the rate of vulcanization and increase the degree of vulcanization and high temperature resistance. In general, Magnesium Oxide and Zinc Oxide both use at the same time, so that the vulcanizate is easy to scorch, and the vulcanization degree is high and the curing speed is fast. The cross-linking degree is much higher than that of the single use.
As a highly precise chemical product, magnesium carbonate requires professional knowledge and rich experience from product development, production process selection, raw material and auxiliary solvent selection, and production process control. Moreover, the downstream applications of magnesium carbonate are numerous, and the requirements of different industries for magnesium carbonate are different, resulting in many kinds of magnesium carbonate products, and the performance between different kinds is different. This also requires high quality of product development and technology management. Therefore, the industry of magnesium carbonate has high technical barriers.
Although magnesium carbonate has not been added to the downstream customer's products, it has an important impact on the performance and quality of its products. Therefore, the downstream customers generally have high requirements for the quality of magnesium carbonate and the stability of supply. In order to keep the product quality stable, magnesium carbonate downstream customers choose carefully every kind of magnesium carbonate which affects the product's coloring property, and often need a long time rigorous test and verification. In order to ensure the stability and adequacy of supply, downstream customers often need to consider whether suppliers have corresponding production, matching capabilities and growth potential, and put forward higher requirements for magnesium carbonate production enterprises. As soon as the downstream customers have trust in magnesium carbonate and magnesium carbonate production enterprises, loyalty will be higher. Due to the lack of stable product quality verification, it is difficult for new entrants to get customers' trust and order in a short time. Therefore, there are high brand and customer cognitive barriers in MgO industry.
