How much should light partition board magnesium oxide content by

How much Magnesium Oxide should be used for lightweight partition board?

Light partition board must use 80% or 85% in the content of Magnesium Oxide Magnesium Oxide, magnesia factory, magnesium plant 80-85% content is Magnesium Oxide Magnesium Oxide Magnesium Oxide do the activity contents. Light partition board needs Magnesium Oxide activity, and the activity of Magnesium Oxide content is not understood by many manufacturers,. The activity of Magnesium Oxide mainly accelerated the speed of solidification, the activity of Magnesium Oxide with 80 content was above 60, and the activity of Magnesium Oxide with 85 content was above 65. If the light partition board with 75 content of Magnesium Oxide will appear very serious consequences, a lot of new lightweight partition board manufacturers do not understand electrical grade magnesium oxide, 97 fused magnesia, fused magnesia content of 98 75% Magnesium Oxide activity in 55, if the customer selects the Magnesium Oxide of Magnesium Oxide live below 60%, directly LED light partition board plate will bring strength is not enough, serious cracks, directly lead to broken plates, manufacturers suffered serious losses, light partition board made out of scrapped, so should use the Magnesium Oxide 80-85% content in Magnesium Oxide, active in more than 60, so as to ensure the light partition plate strength, service life long
