Structure illustration:

    The interior of the test chamber is made of stainless steel plates, and its shell adopts high quality static mold or SUS304 stainless drawbench steel plate. A fiberglass heat preservation layer is placed between outer shell and the working chamber, which guarantees the uniformity of the chamber with no heat escaping from inside. The wind comes in from the bottom of the chamber and escapes through the top. The air in the chamber is forced to circulate y using acentric fan. Airproof liners made of epispastic silicon rubbers are embedded around the chamber gate.

 

Uses and performance:

    The 401B aging test chamber is suitable for thermal ageing test of various rubber and plastics products, electric insulating materials and other materials. The working temperature may be fixed at any time when the temperature varies from room temperature to 250 . In addition, the temperature could remain constant by the use of automation system so that aging test can be conducted within a short time period.

   The result of aging test is determined by the precision of temperature adjustment and the distribution of temperature in the chamber. Our aging test chamber is manufactured drawing strengths from foreign products of the same category. The wind adjusters are installed on both sides of the thermal wind chamber in order to adjust the distribution of temperature inside. The adjustable ventilation volume ranges from 0-100 times per hour in case of continuous blasting.

    The product conforms with the test method standard of JB/T 7444, i.e. Test Methods of thermal ageing test chamber.
