3. the structure overview
    WTB-401A heat aging test box is a series of products after the original series of products have been modified. After the product is modified, it is energy-saving, beautiful and practical, with a capacity of 100 liters and 140 liters. Non-standard can be specially processed according to user requirements. All specifications of aging test chamber shells are made of high-quality steel plate welded, surface baking varnish, inner chamber steel plate sprayed with temperature-resistant silver paint or stainless steel, with two to 50% shelf. The bracket is equipped with a turntable in the middle, and the insulation layer is insulated with ultra-fine glass wool. The door has a double-glazed observation window, and the joint between the studio and the door is equipped with a heat-resistant asbestos rope to ensure the seal between the studio and the door. The power switch, temperature controller and other operating parts of the aging test box are concentrated in the control area on the left side of the front of the box, and operate according to the indicator.
   The heating thermostat system in the box is composed of a fan, an electric heater, a suitable air duct structure and a temperature controller. When the power is turned on, the fan simultaneously operates to directly place the heat generated by the electric heating on the rear side of the box through the air passage. The circulating wind is formed, and the air is dried through the working chamber and then sucked into the fan, so that the temperature is evenly circulated.
   The temperature controller is an intelligent digital display with high temperature control accuracy, set temperature with protection device and timing function.

4. the method of use
   4.1. Put the dried items into the aging test box, turn off the power after closing the door.
   4.2. Turn the power switch to ‘on’. At this time, the power indicator lights up, and the digital display temperature controller has a digital display.
   4.3. The temperature controller settings are shown in Appendix 1. The temperature controller displays the temperature inside the box. Under normal circumstances, the temperature control enters a constant temperature state after heating for 90 minutes. (Note: The intelligent temperature controller refers to the 'operation method' below)
   4.4. When the required working temperature is relatively low, the secondary setting method can be used. If the working temperature is 80 °C, the first time can be set to 70 °C, and when the temperature overshoots back down, the second time is set to 80. °C, this can reduce or even eliminate the temperature overshoot phenomenon, so that the temperature inside the box enters the constant temperature as soon as possible.
   4.5, according to different items, different degrees of humidity, choose different drying temperatures and time.
   4.6. After the drying is finished, turn the power switch to ‘‘Off’’, but you can't open the box door and take out the items immediately. Be careful of burns. You can open the box door first to lower the temperature inside the box and then take out the items.
