Technical parameters of plastic lining plate:
| ITEM | DATA | REMARK |
| Wear rate(10-7cm3/Kgm) | 1.0 | 3 times than wood |
| Corrosion degree(g/m3) | ≥±2 | 3 times than wood |
| hardness(Shao's D) | 70~84 | |
| Martin heat resistance(℃) | 0~65 | |
| density(g/cm3) | 0.97~0.99 | General wood density is 0.85 |
| Impact strength(kg.cm/cm2) | 7.1~9.5 | |
| Compressible strength(MPa) | 68.5 | Wood bearing stress is 6 |
| Bending strength(MPa) | 61.5 | Wood bending strength was 6 |
| Water absorption rate(%) | 0.01 | |
1. The mechanical strength is high, and the service life is long.
The compressible strength is 7~10 times higher than that of the
wood lining, no crushed, and rope groove rubbed phenomena etc. The
service life is 5 times higher than that of the wood liner.
2. Wide range of application
Sun-crack and moisture resistance, no Sun-crack or decay of wood
liner,especially suitable for mine drench water and corrosion
resistance and being used in high corrosive harsh environment and
down-hole conditions.
3. The proportion is light, and no water absorption
The proportion is 0.98, which is lighter than the wood lining after
water absorption.So it will not increase the reactive power and
rotational inertia of the equipment.
4. Compression molding, smooth rope groove surface
The installation is convenient. The wire rope are arranged in
alignment. And the phenomena of rope skipping or bitten rope will
not occur, which greatly extends the service life of the steel wire
rope.
The product after more than ten years in the drum diameter 0.8 m -
6 m the various types of single rope mine hoist and testing show
that the use of plastic lining compared with wood liner has the
following features:
1. High mechanical strength, long service life.
Compressive strength of 7 ~ 10 times higher than the wood liner,
there will not be crushed, rope groove rub inequality, more than 5
times higher than that of wood liner service life.
2. Not bibulous, light-weight.
Proportion is 0.98, are less than a wood liner after water
absorption, so as not to increase the moment of inertia and the
reactive power equipment.
3. The moulding, rope groove surface is smooth.
Easy installation, wire rope neatly, there will be no bite the
phenomenon such as rope, rope skipping, greatly extend the service
life of wire rope.
Wooden plate seriously affect the service life of wire rope, has to
be eliminated;The other is a wooden plate on the drum surface
installation, but due to the wood grain of lining board of the
nature and direction of the copper wire rope rope is the same, very
Easy to rub flat convex wooden line pull.Arrange disorder resulting
in copper wire rope, and a bit rope, rope skipping.In the early
ninety s, our factory has developed resistant engineering plastic
plate, and
Wooden plate than has the following advantages:
1, long service life, higher than that of wood liner tested the
useful life of more than 5 times,
2, the allowable contact pressure is big, there will be no lining
crush, rope groove rub equality.
3, resistance to dry, wet resistance performance is good,
especially to mine used under the bad environment.
4, light weight, not bibulous, does not increase the equipment move
inertia and reactive power.
5, die forming, smooth surface, size precision, easy installation,
save time and effort.Steel wire rope neatly, there will be no rope
"bite", "skip" wait for a phenomenon.Comparable to the installation
of the wood liner
Less than half of the workload and production time.
