• the maximum cost-effective ability is achieved at the smallest thickness of the oxide layer, which is sufficient to eliminate the impact of electrical voltages.
• the pressure takes place in the first place in the world, where the resulting redundant layer is more toxic. Otherwise, due to the increased overload of the elec- tric charge in the charge, the product is a gas and gas appliance, which means that there is a risk of increased weight in the world.

If the temperature is lower than 70 ° C, the stability of the gas and gas spoils will deteriorate, the process will undergo significant 5 vibration and voltage fluctuations; at temperatures above 90 ° C, the quality of the products is reduced due to an increase in the chemical activity of electrolytes and disruption of heat loss - 10 -

For this reason, at the lower end of the loaded part of the appliance, where after the absence of insulation, there is no need for a gas treatment. Due to the high temperature, which develops in the channels of electrical discharges, which reduce the voltage, the burning of the insulation on - - the return of the enemy.
