ASTMD 4329 QUV Lamp Weather Test Chamber Programmable Cycle Test

ASTMD 4329 QUV Lamp Weather Test Chamber Programable Cycle test

Applicable industries:

It is widely used to control products quality in measuring quality control; Rubber & Plastics; automobile production; wire and cable; packing materials; instruments and meters; medical equipment; civilian nuclear energy; civil aviation; colleges and universities; research laboratories; inspection arbitration, and technical supervision departments and other rubber products.

Loading capacity

That is, the mixing capacity. Insufficient capacity will reduce the shearing and kneading effect on the rubber, and even the rubber slip and rotor idling, resulting in poor mixing effect. On the contrary, the capacity is too large, the rubber turnover is difficult, the position of the upper top bolt is improper, and some rubber is retained at the neck of the feeding port, resulting in uneven mixing of rubber, long mixing time, equipment overload and high energy consumption. Therefore, the mixing capacity should be appropriate, usually 60% ~ 70% of the total effective volume of the closed chamber.

Main function:

This machine is used to test the ozone environment, the characteristics of crack-resistant rubber, ozone resistance testing machine, can control and adjust the concentration of ozone environment, to determine the anti-ozone properties of the specimen.

Main feature:

Equipment by the occurrence of silent and efficient ozone generator ozone gas, and a certain amount of air processed, the switch in the mixture into the chamber, the continuous line UV detector to detect the concentration of ozone, ozone generator control feedback to the systems to control system settings according to the occurrence of effective control of ozone to the ozone chamber to maintain the appropriate concentration of work by heating humidification systems to meet all the test conditions.

Techincal parameter:

Equipment summary:

Ozone is a major factor in rubber cracking although it is rare in the atmosphere, ozone aging tank simulates and enhance the condition of ozone in the atmosphere to study the effects of ozone on rubber, and then identify and evaluate the method to resist ozone and aging for rubber, adopt effective anti-aging measures to enhance the life of rubber products.
