The UV aging test chamber uses a fluorescent UV lamp as a light source to simulate the material by simulating ultraviolet radiation and condensation in natural sunlight, so it is especially important for the maintenance of the UV aging test machine. Let's take a look at it. Some maintenance knowledge.
In order to make the UV aging tester work better and maintain a good condition for a long time, and the instrument recommendations, please follow the following items for maintenance:
1. If the UV aging tester is in a non-operating condition, keep it dry and disconnect the power supply.
2. After the test, drain the water from the test machine and dry the studio and the cabinet.
3. After use, remember to put the plastic cover on it to avoid dust intrusion. If there is dust, it should be removed in time.
4. The sensing device in the working room should not be subjected to strong impact;
5, UV aging test chamber is best placed in a well ventilated place (recommended to install ventilation fan, keep indoor ventilation), should not be installed in dusty places;
6. If the UV aging test chamber fails and cannot be eliminated, please find the relevant personnel, do not disassemble it;
7. The test box is not used for a long time. If it is used again, the water source, power supply and various components must be carefully checked.

Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge.
A Manual Caulking Gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product.
Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.
