6 characteristics

1, the oxidation are suppressed
low price dry oven with high quality for laboratory furnace of iron oxide is based on the following two reasons: on the one hand, because of high low price dry oven with high quality for laboratory degree, the oxidation medium is extremely thin, gas - solid interface on the oxidation reaction speed is very slow, no visible oxide film formed. On the other hand, under the condition of low price dry oven with high quality for laboratory heating, equivalent to in a protective atmosphere heating, inhibit the oxidation of iron. And due to the increasing the proportion of reducing gases H2, CO, even with trace oxidation, the formation of oxide film will be restored.

2, purifying effect
In a low price dry oven with high quality for laboratory furnace under the condition of oxygen tension is low, metal oxide can be decomposed into the oxide, oxide in a low price dry oven with high quality for laboratory heating easy sublimation and volatilization, walk by a specific low price dry oven with high quality for laboratory pump. In addition, attached to the surface of the oil is a compound of carbon, hydrogen, oxygen and vapour pressure is higher, under the condition of low price dry oven with high quality for laboratory heating volatile or decomposition, low price dry oven with high quality for laboratory pump away, have the effect of purify surface.

3, degassing effect
Usually, there is always a certain amount of gas dissolved in the metal, such as H2, O2, N2, etc., under the condition of low price dry oven with high quality for laboratory heat treatment, the higher the degree of low price dry oven with high quality for laboratory, the lower the air pressure, the higher the temperature, the more conducive to spread to the metal surface gas evolution.

4, evaporation
Very little pressure evaporation of the metals and their alloys, but under the condition of low price dry oven with high quality for laboratory heat treatment, metal surface alloying elements of evaporation is very serious, and sometimes it will cause poor surface alloying elements, which changes the alloy tissue, decreased mechanical properties.

5.In a low price dry oven with high quality for laboratory heating, because of the thin gas, conduction, convection and radiation in only three types of heat transfer is given priority to with radiation, and under 600 °C, the radiation effect is very weak, so a low price dry oven with high quality for laboratory heating speed is slow.
