High temperature and moisture resistant electrical grade Magnesium Oxide JS-M8

This product is a series of damp-proof and high-temperature resistant magnesium oxide, including A, B, C, D four grades, suitable for different levels of work load air-fired heating components, not suitable for high-temperature heat treatment (such as annealing at 1050 C), with strong moisture-proof ability, can be easily sealed, sealed before the need to do 200 350 C / 2 - 4 hours drying treatment of the components.

Type: moisture resistant and high temperature electrical grade Magnesium Oxide M series

Characteristics and uses:

M series belongs to damp-proof and high-temperature electrical magnesia with four specifications. It is suitable for making medium and high-temperature air-fired electric heating elements. It can bear the highest air-fired temperature of 750 degrees. It is not suitable for high-temperature heat treatment (such as annealing at 1050 degrees centigrade). It has strong moisture-proof ability and can be easily sealed. It is recommended that 200-350 degrees centigrade/2-4 should be done before sealing. Dry treatment.

It is suitable for all kinds of intermediate and medium and high grade load meson heaters. Such as: water heater tube, oven tube, mosquito coil tube and so on.

Note: + 425 m and - 45 m contents will be strictly controlled within the prescribed range, in order to obtain the required compaction and flow rate, the content of other items may exceed the above range. (special requirements can be produced according to customer needs)

Flow density and density:

The density of compaction is T.D. (g/cm3): 2.30-2.45 g/cm3.

Flow velocity (F.T. s/100g): 36 + 4

Flow rate (F.R. s/100g): 180 + 20

Packing:

25KG cartons, woven bags, 1 tons of pallets or packaging according to customer requirements.

Safety and storage:

Electrotechnical grade magnesia powder is non-toxic and has trace dust. It is recommended to wear masks and gloves during use. The product should be stored in dry place, and it is recommended to be used within 12 months after the factory is released.

Special description of Magnesium Oxide M series for high temperature and moisture resistance.

1) strong moisture resistance:

At present, most of the high-temperature electrical magnesia powders produced on the market can only reach 1000 M_, or even do not have the ability of moisture-proof, and the company's high-temperature electrical magnesia M series products, moisture-proof ability is greater than 2000M_, not sealed by wet test (humidity 92% temperature 50 degrees) 72 hours or more long time storage There is no decline in insulation. Strong moisture resistance can greatly enhance the production cycle. To reduce sealing material requirements, ordinary silica gel can be used for sealing.

2) strong resistance to heat:

The product can be used at a maximum temperature of 750 degrees, filling the shortcomings of high-temperature powder without moisture-proof ability; according to the technical specifications of electric heating components, choose products of different specifications and grades.

3) the product is uniform in color, beautiful in appearance and small in dust, which is beneficial to improving the environment of adding powder.
