1, the quality of rubber
The core of the quality of the buffer strip is the quality of the rubber. However, the current price difference between the buffer strips in the domestic market is mainly due to the fact that the rubber used is not the same, which directly causes a large price gap.
When the buffer strip is subjected to the oblique cutting force, it mainly relies on the rubber elasticity of the buffer strip itself to offset the impact force received. The state does not have a uniform inspection and implementation standard for its buffer strip.
Become a relatively confusing market;
2, bonding strength
The buffer strip does not see the bond strength from the surface, which is the most headache for users, because it can only be found during use, and the international terminology is stripping.
According to the coefficient, the bond strength test must be tested by a professional machine, which makes it difficult to guarantee the performance index of the buffer strip, and the actual bond strength can be achieved internationally.
For special thermal vulcanization technology, domestic manufacturers are relatively few;
3, the connection method
At present, the connection methods are generally classified into two categories in China. One type is an aluminum alloy structure. This structure is a relatively backward connection method in Germany in the 1970s and 1980s. The main problem is that it is easy to cause the buffer strip to sway.
Steel is not strong, posing potential safety hazards to users. One type is steel connection. Rita rubber mainly uses this connection structure; while in our country, the aluminum alloy structure is prohibited from being used underground.
Because aluminum is more active and prone to reaction, there are certain safety hazards;
4. Misunderstandings of understanding
Flame-retardant and anti-static buffer strips are misunderstood by users who use them. Generally, whether it is a flame-retardant buffer strip or an anti-static buffer strip or a double-resistance buffer strip, it is mainly for wear-resistant layers and rubber.
A flame retardant or antistatic agent is added between the two, so that the color of the buffer strip can only be black, so for safety reasons, it is best to choose a manufacturer that can test the experiment, such as Rita rubber.
Really ensure the quality of its buffer strips;
5, the quality of the wear layer
In fact, the wear-resistant layer mainly refers to the ultra-high molecular weight polyethylene plate, the molecular weight affects the expiration performance, and the different molecular weight affects the wear resistance and impact resistance. A suitable molecular weight also affects.
To the performance of the buffer strip, the flame retardant antistatic buffer strip Rita uses a specific material suitable for underground use, which is different from the general manufacturer, so the quality is better.
There are two main production processes. The first type micro-prism-type body reflective logo, mainly using a high-quality, durable micro-prism structure of the reflective material. The structure for the reflecting marking quality requirements of the demanding high reflectivity, its pure, bright color to improve the significance of the day marked.
The second process is made of sealed capsule type reflective material, the width for the logo is 50mm, the surface color is white (150mm).Red interval. In which, white is reflective material natural color, red ink printed on the surface film by silk-screen printing.The surface of the material has a regular hexagonal embossed reflective material structure. Including transparent surface film, air film, glass beads, support layer, resin layer, gum and paper.
