Ozone aging box operation precautions

Ozone aging tank can be used in rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath and other products. Under static tensile deformation, it is exposed to airtight and constant temperature test chambers with constant ozone concentration and sealed time. The sample is tested to determine the degree of resistance to cracking or other properties from the surface of the sample to assess the ozone aging resistance of the rubber.
In the usual test operation, we should pay attention to the following points:
1. The power supply should be equipped with an overloaded fuse device in the power supply line for special use of this box to ensure that the equipment has a good grounding device, which not only ensures the safety of the test personnel, but also ensures the service life of the equipment.
2. After the samples are numbered one by one, place the samples on the test carousel, and do not contact each other and collide with each other to ensure that the ozone is tested at a uniform concentration and on each sample during the test.
3. Close the door after the above points are completed. Turn off each switch of the control system, plug the power plug into the power switch, turn it on automatically, and the power indicator of the control system will be on. If you need to heat up, you must turn on the switch (ie high temperature switch and low temperature switch), then adjust the automatic control. system
4. The ozone aging test chamber should be placed in a well-ventilated indoor horizontal position, and no flammable or explosive materials should be placed around it.
5. One of the knife switches of the iron shell should be installed in the power supply line for the special case. Please check the electrical performance of the box before the grounding of the outer casing. Please pay attention to whether there is any open circuit or leakage. The instrument has no explosion-proof device. Do not put flammable and explosive materials into the dry.
6, the contents of the box should not be over-squeezed, you must leave room for hot air circulation.

Pull the Silk

Uneven, with the halftone screen tension will cause photosensitive paste coated scraping and distribution is uneven, thus further affecting the printing quality. At the same time, the wire mesh of different network version tension inconsistent, give chromatic trouble, and can not even sets. Different screen brands, same brand, not the number of different mesh wire diameter wire mesh, tension requirements are not the same. For this problem, consulting to the screen manufacturer. Aerodynamic top mesh netting machines, KC Printing Machinery Company production, mechanical Stretching Machine operating basically meet the requirements of different types of printing.
