Magnesium oxide as an important chemical industry additives, there are some specifications needed to pay attention in different industry. Below is our industry production experience for many years, manufacturers can make it as a reference.
1.Adhesive industry. The magnesium oxide content of ferric can not too high, or the adhesive will change colour. Next the content of calcium can not too high, because high content of calcium and screenings will appear statified phenomenon. The activity of magnesium oxide between 120 to 150 is the best, that means, activity too high may due to intense response curve, and it is bad for adhesive products.
2.Tire industry. 90%≤MgO≤95%, the content of MgO can not under 90%. Loss On Lgnition%≤0.5, moisture%≤0.5, have to say, bulk density is also an important specification.
3.Wire & Cable industry. The magnesium oxide content of calcium can not too high, or the Wire & Cable will easily become brittle, even occur leakage and other dangerous situations, those are influence its service life. Moisture content can not too high, or it will occur blister of cable skin. Screenings content decided the Trachoma and Electric Leakage problems.
Detailed specifications of magnesium oxide used in different application, you can get in touch with Hebei Meishen Technology Co.,LTD at you free time. We are glad to help you solve production problems!
