EVA Faux Teak Sheet comes in double layers EVA material, it appears grooves to show the bottom color after the roller cutting, which makes it looks like a teak wood. So instead of using a real wood for the boat flooring, more and more people put their focus on this no maintain and Eco-friendly EVA marine sheet.
Made from marine grade UV resistant, closed cell, high density EVA foam material, it stands perfectly even in a strong sunlight area. And the EVA foam material makes it softer and more comfortable for people standing there bare feet than real teak or PVC teak. Some would concerned if the boat mat would be not durable to use since it is made from foam material. Well, it may not hard like real teak or PVC teak, and compete the durability with those two, but with a higher density EVA foam, we are able to compete with other suppliers who try to compromise the density to reach to a lower price.
The sheet comes in 230cm x 90cm or 250cm x 120cm, user can cut the sheets into size to fit the shape of boat decking, then just peel and stick since the sheets we offer is with 3M adhesive on the backing. It can be applied on boat decking of course, and other like swim platform pad, helm station pad or simple seat pad.
What's more, this kind of sheets can be applied in recreation vehicle for luxury flooring, a safe traction mat for the edge of swimming pool, a beautiful looking for flooring in room or balcony.

Maintenance of single-beam UV-visible spectrophotometer
Maintenance of single-beam UV-visible spectrophotometer
(1) Single-beam UV-visible spectrophotometer laboratory environment regular cleaning
(2) Maintenance of the light source
If the position of the lamp is improperly installed, the performance of the instrument will be degraded, noise will increase, and stray light will increase. When using a micro-pool, the position of the lamp and rack needs to be more calibrated.
After the light source lamp accidentally adheres to the oil, turn off the light source and wipe it with absolute ethanol. Do not touch the xenon lamp or tungsten lamp with your hands. The dust can be blown off with the earball. Aging of the lamp can cause insufficient energy, causing degradation of instrument performance, increased noise, and increased stray light. If the light source lamp is unstable or exceeds the service life, the new lamp should be replaced. When the instrument stops working, the power must be turned off, the selector switch should be turned "off", and the instrument should not be turned on when not in use.
(3) Input power
In order to enhance the anti-jamming performance of the instrument, it is recommended to use an electronic AC stabilizer of 200W or more or an AC constant voltage regulator to ensure the stability of the voltage during operation. Before using, check the safety of the instrument, whether the power supply voltage is normal, and whether the grounding wire is firm and reliable. After confirming, you can turn on the power supply. Too large input power (220V AC, fluctuations will lead to instrument instability and performance degradation. Single-source UV-Vis spectrophotometers are usually caused by insufficient power, AC power line aging or high power on the power line. The load is caused. When the instrument stops working, turn off the power and turn off the switch.
(4) Other maintenance of the instrument
1 After the instrument is used, the residual liquid in the sample chamber should be cleaned in time. If a solution is spilled into the sample chamber, it must be cleaned up in a timely manner to keep the sample chamber dry and free from contamination.
2 The absorption rod holder should be pulled smoothly in the specified direction. If the force is too strong and too fast, and the sliding is not smooth, apply a proper amount of Vaseline evenly on the slider.
3 After using the instrument for a certain period of time, clean the sealing window of the optical box, calibrate the optical path if necessary, clean the mechanical parts and necessary lubrication.
4 Do not pour the test sample over the single-beam UV-Vis spectrophotometer to prevent the sample from contaminating the instrument surface and damaging the instrument. When the instrument case, sample compartment cover, and operating keyboard are dirty, wipe with a soft cloth or paper towel.
