Muffle Furnace for Ash Determination

★☆The muffle furnace produced by our company is widely used in laboratories and laboratories of plastic processing, colleges and universities, industrial and 

      mining enterprises, and scientific research institutions. It is used for element analysis, physical measurement, raw material roasting, quenching, annealing, 

      tempering and other heat treatment of small workpieces. It can also be used for high-temperature heating such as sintering, dissolving, and analysis of 

      metals and ceramics.

★☆The effect of the muffle furnace on plastics is mainly high-temperature decomposition. The plastic sample is completely burned in the muffle furnace (above 

      600°C), and the content of inorganic fillers can be determined.

★☆This equipment can intelligently control time and temperature in sections, and meets the standards of ISO 3451-1:1997, "GB/T9345.1-2008 Plastics 

      Determination of Ash Content Part 1 General Method".

Made of high-quality steel plate 

Ash content determination muffle furnace box-type resistance furnace adopts domestic advanced technology. The furnace shell is made of high-quality steel plate by folding welding, and the control box and the furnace body are an integrated structure. 

Appearance is beautiful

The appearance is beautiful, avoiding the cumbersome installation of customers. The inner furnace lining is a rectangular integral furnace lining made of high aluminum and silicon carbide refractory materials. The spiral heating element made of iron-nickel-chromium-aluminum alloy wire is passed through the wire grooves on the upper, lower, left and right of the inner furnace lining. Heating up and down, left and right. 

Sealed structure

The furnace is a sealed structure, and the inner furnace and the furnace shell are built with refractory fiber aluminum silicate wool and diatomaceous earth products as an insulation layer.

Chimney smoke exhaust device

The overall design is reasonable and has a long service life. The furnace door and chimney exhaust device are opened on the left, which is easy to operate. Beautiful shape, sophisticated workmanship, strong and durable, not easy to deform.

1. Open the machines everyday periodically.
2. Operated by the specialist.
3. The equipment and accessories must be deposit in the dry environment.
4. After testing the accessories should be added wiping grease rust, and remove the rust great before test.
5. When the test finished, the power should be closed to avoid any accident.
