In recent years, China's fiberglass industry has developed rapidly, which is driven by domestic and foreign markets. The expansion of the international market is not only due to the growth of the total demand, but also due to the low profit of international enterprises in the early stage after the launch of the industry, leaving room for the development of domestic enterprises in the international market. At the same time, the rapid development of downstream consumption industry promotes the growth of the domestic market, which is absolutely a very big good news for the downstream magnesium oxide industry of FRP.
Magnesium oxide plays a very important role in glass fiber reinforced plastics, which can thicken and increase the brightness of glass fiber reinforced plastics. Therefore, compared with the same type of glass fiber reinforced plastic, usually using magnesium oxide raw materials will be more popular in the market. However, not all types of magnesium oxide can be added to the glass fiber reinforced plastic, only the use of glass fiber reinforced plastic magnesium oxide can achieve the ideal effect, and glass fiber reinforced plastic magnesium oxide indicators are: magnesium oxide ≥90%, moisture ≤0.5%, iodine absorption value 60-120mgl/g, sieve residue 0.01%, 150 mesh, whiteness good, good dispersion.
Firstly, the special magnesium oxide for glass reinforced plastic needs to provide different products according to different indicators of customers Second, the requirements for magnesium oxide vary greatly depending on the resin used in the production process. Hebei meishen technology co., LTD can provide professional customized services according to the specific requirements of some indicators of customers.
Generally speaking, active magnesium oxide is better and needs to be adjusted according to climate change. In general, in winter, magnesium oxide requires higher activity ;In summer, the activity of active magnesium oxide is required to be low. The activity of magnesium oxide will affect the reaction speed. In most cases, the activity is high and the thickening is too fast. Low activity, the sheet will be soft, dry.
