The composite floor is very widely used, but most people pay more attention to the quality of the floor, and ignore the quality of the floor line. Because the type of floorboard and the material of the composite floor are many, the quality is uneven.
Introduction to the floor material: At present, the skirts sold on the market mainly include logs, medium density fiberboard, high density fiberboard and new material PVC polymer foaming materials.
Among them: the log line can not be denied, certainly the quality and environmental protection are better, but the price is not cheap, the density fiberboard floor line price is general, but there is the problem of water absorption deformation, daily maintenance needs to be careful. PVC polymer foaming materials account for a large market share because of its characteristics of no lead, no ammonia, free formaldehyde and other harmful gases. Other materials should pay attention to the limit value of formaldehyde emission.
If you buy a poor quality skirting line, it will have a certain degree of influence on itself and the quality of the floor. Therefore, when selecting the floor, the owner should also spend some time thinking about the difference in the quality of the floor and the quality of the home improvement. turn off.
1) many of our customers struggle with what materials to choose for the battery Spring, which is a good choice for cold plate, manganese steel, brass, and phosphor bronze. Which of these materials to choose depends on the battery`s plastic shell structure and the value of the product and the environment in which it is used. Like this common battery sheet is generally used cold nickel plating on the line, nickel plating after a good effect, cost is also very low. If your product uses the environment to be very humid that also may consider does with the brass material, this will cost many times high. (2) the ordinary cold plate nickel-plated Daxin hardware spring can pass through salt spray for 72 hours without rusting after being sealed with oil. Such spring-loaded battery springs are usually made of manganese steel (65M) or phosphor bronze. Some customers may think that stainless steel will be more elastic, but you don`t take into account that stainless steel is tin-free, meaning you can`t solder it or it`s difficult to solder it. In fact, the material of manganese steel after heat treatment elastic and stainless steel is similar. For Phosphor bronze material is also commonly used in this type of products, elastic or good, not rust, low resistance, easy to weld, but the cost of phosphor bronze is higher.
Battery spring, divided into positive battery spring, negative battery spring, positive and negative battery spring
