How to choose a cork floor:
First, look at the surface sanding surface is not very smooth, there are no bulging particles, cork particles are pure, this is the first step in the selection of cork flooring, is also a very important step.
Second, look at whether the side length of the cork floor is straight, the method is: take 4 pieces of the same floor, spread on the glass or on the flat ground, and assemble it to see if it is seamed.
Third, check the bending strength of the board surface, the method is to close the two diagonal lines of the floor to see if there is crack on the curved surface, and no crack is a quality product.
Fourth, the inspection of the bonding strength. The method is to put a small piece of the pattern into the boiling water bubble, and find that the smooth surface of the sanding becomes a suede, and the uneven surface, the product is a non-conforming product, and the surface of the high quality product should have no obvious change.
KMJ SF6 Gas Density Relay
It is applicable for monitoring the SF6 gas density in a sealed vessel. It can show gas density values on the site. When the gas density reaches the preset value, the contact-making device will send alarm and control signals. It can be widely used in electric equipment including SF6-insulated composite apparatus, circuit breakers, pole-mounted switches, transformers and mutual inductors. It provides solutions for new construction of transformer substations and inteligent reconstruction of existing transformer substations.
