Before using flame-retardant high-molecular-weight polyethylene boards, proper installation is crucial and cannot be overlooked; it is also a vital prerequisite for enhancing the value of wear-resistant coal storage lining boards. Generally, the method for fixing wear-resistant coal storage lining boards on steel structures is by welding bolts. The reason for using this method is that the expansion coefficient of the wear-resistant coal storage lining boards is 2×10^-4/°C. In cases where there are significant changes in operating or environmental temperatures, the fixed form of the flame-retardant high-molecular-weight polyethylene boards must consider its free expansion or contraction. This allows for variations in length, forming a smooth plastic plane within the storage bin, which is conducive to material flow and ensures the board's full functionality.
Let me explain the performance of our flame-retardant high molecular weight polyethylene boards in industrial applications:
Flame-retardant high molecular weight polyethylene sheets have superior mechanical properties compared to standard high-density polyethylene. They exhibit outstanding impact resistance, stress-crack resistance, high-temperature creep resistance, low friction coefficient, and self-lubricating properties. The flame-retardant high molecular weight polyethylene sheet manufacturers also offer excellent chemical corrosion resistance, noise damping, and radiation resistance.
Use temperature: 100-110°C. Excellent cold resistance, can be used at -269°C. Density: 0.985 g/cm³, molecular weight: 2 million. The product has a tensile strength at break of 40MPa, elongation at break of 350%, flexural modulus of elasticity of 600MPa, and cantilever beam notch impact is not broken. Wear rate (MPC method): 20mm.
High molecular weight polyethylene lining plate, which is polyethylene with a molecular weight above one million; I assume most of you are familiar with this. So, how much do you know about the fixed lining plate technology? Let's analyze it.
Tapped steel bolts with locknuts (anti-loosening).
(2) Shock screws with washers, flame-retardant, ShanghaiHigh molecular weight polyethylene plates, by hammering threaded screws into steel plates, nuts can be omitted. In both cases, a substantial amount of drilling work is required, which means increased labor and tool wear costs, leading to higher installation expenses.
