Tray thermal extension test apparatus

I. Product introduction:

Test standard: It is in line with Standard GB/T2951-2008 and Standard GB5013-2008, and it shall be used together with aging test chamber.

II. Key parameters:

Maximum number of samples in a test:3

1, temperature setting: rubber products, 180 ℃, crosslinked polyethylene products 200 ℃.

2. When the temperature rises to the required temperature, clamp the dumbbell test piece onto the hot extension clamping device, and add the weight below.

3. Weight distribution calculation: 20.4 x specimen thickness * 4(including clamps, supporting rods and weights).

4, in the middle of the dumbbell specimens on the effective distance of 20 mm (the length of the small dumbbell specimen is 10 mm) tag line, the length of the dumbbell to take three, put hot stretch of a complete set of equipment in have ascended to the temperature of the central part of the aging box.

Close the door of the aging chamber and read the elongation of the specimen after 15 minutes.
