Focus on how to maintain the ultraviolet aging resistance test box
The ultraviolet aging resistance test box simulates the damage caused by the sun's ultraviolet light, and conducts the urban weather resistance test on the material by exposing the tested material to light under controlled high temperature. It uses ultraviolet lamps to simulate the radiation effect of sunlight, and simulates dew and rain through condensation and water spray. In just a few days or weeks, the ultraviolet radiation equipment can reproduce what it takes months or even years outdoors. Damage that only occurs over time, including fading, color change, tarnishing, chalking, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc. The test results can be used to select new materials and improve current Have materials, or evaluate changes in material formulations.
How to maintain the ultraviolet aging resistance test chamber during daily use? Application personnel should pay attention to the following points:
1. Non-full-time operators shall not operate at will.
2. Do not subject the sensing device in the working room to strong impact
3. Adequate water supply must be maintained during equipment operation.
4. During the test phase, the time to open the door should be minimized
5. After a long period of non-use, if you need to use it again, you must carefully check the water source, power supply and various components, and then start the equipment after confirming that it is correct.
6. Because ultraviolet radiation has a strong hazard to personnel (especially eyes), operators should minimize exposure to ultraviolet rays (contact time should be less than 1min). It is recommended that operators wear protective goggles and protective sleeves.
7. Please contact our company when the equipment fails to be solved by yourself.
Limiting conditions for samples of ultraviolet aging resistance test box:
Test and storage of flammable, explosive and volatile substance samples
Test and storage of corrosive material samples
Testing or storage of biological samples
Test and storage of strong electromagnetic emission source samples
Heat Exchanger Plate&gasket
Plate and gasket are the critical part of a removable Plate Heat Exchanger. The main function of the plate is to isolate the medium and perform heat exchange. Its main materials are stainless steel (304/304L, 316/316L, 254SMO), titanium, nickel, titanium-palladium alloy, Hastelloy, etc. The sealing gasket is installed in the gasket groove around the plates to seal the periphery between the plates to prevent the fluid from leaking out, and according to the design requirements, seal part of the corner holes so that the hot and cold media flow according to their own flow paths. The structure of the plate heat exchanger consists of a fixed frame, a movable frame and corrugated plates sandwiched between the two frames. Hot and cold liquids pass sequentially through the area between the corrugated plates separated by sealed elastomer paths. To prevent leaks, good gasket elastomers are installed around the perimeter of the plates and large fastening bolts are used to hold the plates together. The structure of the plate heat exchanger makes sealing a key part of this equipment, responsible for the service life of the entire equipment. Depending on the process medium, the gasket must be chemically and/or temperature resistant. Spetech supplies seals for most existing plate heat exchangers: power industry, petroleum processing, food and beverage industry, sugar industry, chemical, pulp and paper industry. The most commonly used materials are: NBR, HNBR, EPDM, FPM (different grades). There are two basic ideas for the installation of seals: glue seals and clip seals. Clip-on washers do not require any adhesives for installation. This modification makes it possible to mount the spacers by installing clips in the grooves in the plate. As a result, the gasket is highly resistant to pressure and can be replaced quickly and easily.
