Flame retardant and antistatic blanking mouth buffer strip Underground mining buffer strip (special for underground buffer bed)
1. What are the structural components of the buffer strip?
From top to bottom are polymer polyethylene wear-resistant plates, buffer rubber, metal parts, and special bolts.
2. How many types of buffer strips are there?
Classification of buffer strips: Flame-retardant buffer beds (used underground, in flammable and explosive places) and non-flame-retardant buffer strips (used above mines, power plants, cement plants, factories)
3. Buffering What are the specifications of the strips?
The width and thickness of the buffer strip are fixed (width, thickness), but they are divided into lengths, general specifications and sizes,
Advantages of the buffer strip
. The buffer strip effectively prevents surface contact of the conveyor belt No damage to the conveyor belt
. The conveyor belt is evenly stressed at the blanking port, which greatly reduces daily repair and maintenance costs
. Effectively eliminates material splashing and damage caused by uneven stress on the conveyor belt. Leakage
. The smooth surface of ultra-high density polyethylene reduces the friction of the conveyor belt during operation.
. The arc-shaped design on the surface of the polyethylene layer ensures the smooth operation of the conveyor belt
. The ultra-high elasticity special rubber layer can absorb the impact force of the material to the maximum extent
. Each part of the buffer strip The parts are connected using a hot vulcanization process, making them compact and firm
. The design of the underlying structure makes disassembly and assembly easy and fast
Analysis of problems with the use of buffer strips
The quality of the buffer strip, the core component of the buffer bed, is directly related to the quality of the buffer strip. It affects the quality of the buffering effect, but some dealers blindly pursue profits regardless of the quality of the buffer strips, because inferior buffer strips cause the following problems
The buffer strip is smashed
The buffering of the buffer strip The quality of the rubber layer is poor. The use of inferior waste rubber as the buffer layer results in higher rubber hardness (some unscrupulous merchants even provide buffer rubber with a Shore hardness greater than that). The indicators of resilience and elongation at break are poor, making the buffer strip The impact force cannot be fully absorbed, resulting in the buffer layer of the buffer strip being unable to rely on rubber's softness to overcome stiffness to decompose the stress, resulting in the buffer strip being smashed earlier
(For example, the same material drop height and particle diameter media are different from one piece of rubber Under the same impact conditions as stone rubber, it is easy to conclude that stones are more likely to be smashed). The quality of many manufacturers is far from their advertised quality. Users also do certain tests to ensure the quality of buffer strips.
The buffer strip wears out quickly
The ultra-high molecular weight polyethylene material is commonly used at home and abroad for the wear-resistant layer. This material has a low friction coefficient, high wear resistance, good self-lubricating properties and non-stick properties. From another perspective, the higher the molecular weight, the better the wear resistance and the smoother the surface. It is due to the characteristics of this special material that some manufacturers cannot solve the bonding problem between ultra-high boards and buffer layer rubber, so they choose low-molecular weight ultra-high boards or Other materials are used to solve bonding problems and reduce costs. Of course, there are certain principles and general rules for selecting ultra-high molecular weight and thickness of the wear-resistant layer of buffer strips. Many manufacturers do not understand the working conditions for ultra-high molecular weight and thickness of boards. If the technical requirements are not met, the wear-resistant layer of the buffer strip will wear out quickly.
Buffer strip channeling problem
Various buffer strips
It is often found that buffer strips often have channeling problems. After our on-site analysis, we found that most of the channeling strips do not have aluminum alloy flat connection methods. This Compared with the galvanized steel structure, this connection method accounts for a larger proportion of the buffer strip. The relative rubber content of the buffer layer is less, which reduces the buffering effect of the buffer strip. The bolt and flat connection method cannot effectively decompose the oblique cutting force, which can easily cause channeling and stripping. Affects the service life of the buffer strip.
