Electronic
Ventilated Aging Test Chamber For Heat Shrinkable Tubing /
Industrial
1. Product introduction:
Ventilation-type aging testing chamber used to test the
material characteristic for wire type, skin type, plastic, rubber,
cloth, Equiped with a special ventilation regulator for maintain
the fresh air inside when heating. This testing machine design with
sophisticated air-displacement adjustment device and a digital
voltage meter, current meter, watt-hours, the timer can be used to
measure the air replacement rate. Horizontal circulatory air supply
system and both sides of airflow regulator to ensure the internal
temperature uniformity and stability.
2. Main feature:
The oven used to study the rubber that is heated under the rotary
mode in a fixed period. Tested 1 day at 70 ℃, theoretically
equivalent to 6 months exposed to the outside atmosphere. The oven
is equipped with motor-driven rotary disk, hot-air circulation
system that ensure uniform distribution of temperature.
3. Corresponding standard:
Accord with ASTM D5423-9(R2005)(Ⅱ-Type oven)and ASTMD 5374-93(2005)
UL-1581,GB,VDE,JIS,IEC
4. Applicable industries:
The aging tank used to test the material heat-resisting for polymer
materials (plastics, plastic) and electrical insulation materials,
such as: wire and cable sheathing, heat-shrinkable tubing, rubber
or PVC materials.
