New trend of construction of cement sleeper mine track.

The cement sleepers are suitable for 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg rails, with 600mm, 900mm, 762mm gauge for metal mines and 1435 gauge for railways. Explain how much the rail is and what the gauge is.

The advantages of cement sleepers are good stability, long service life, and low cost for maintenance and repair; the disadvantages are heavy weight, poor elasticity and insulation performance, and cushion insulation cushions must be provided at the bottom of rails.

The cement sleepers are demoulded with steam, the surface is smooth and hard, and there are multiple high-strength steel bars as skeletons, which greatly increase the strength of the cement sleepers. We use C30, C40, C60 cement to ensure the quality of the sleepers from the choice of materials. Steam stripping, natural curing in the later period has greatly strengthened the hardness of the sleeper.

The concrete sleepers have basically replaced the wooden sleepers in the first stage. Its advantages are good stability, long service life, and maintenance and maintenance costs. The cement sleepers are divided into U-rings and bolt pressers according to usage. The price is different. Please specify when purchasing.

Rubber Damper, also known as Shock Absorber, Isolator, and NBR grommet, NBR is a unsaturated rubber copolymer with polar unsaturated carbon chains, which is copolymerized by propenenitrile and butadiene, according to propenenitrile content from low to high, the higher the resistance to oils but the lower the resistance to cold. Oil resistance is the greatest advantage of NBR elastomer so it has excellent resistance to petroleum base oils and non-polar solvents but poor resistance to polar oils and polar solvents.
Nitrile rubber (NBR, Buna-N) grommet provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
