Description:
We can also supply various kinds of composite material with regenerated
resin as per customers' drawings
and specifications instead of ductile
iron and grey
iron castings, such as
water meter tank cover.
The
product is cast by mould, with composite material of regenerated resin.
Compared with the similar
products with
cement or steel, it has better capability
of anti impact
and anti causticity,
and more
light in weight for easy handle,
and can be in different colors. The material can not be used for 2nd time
and no one
will steal it. It is widely used in the checking well of cables, waist water, electrics, gases pipes underground.
Features:
1) Endurable, anti rust, anti aging
and with more life span
2) With more loading capacity, it has as much strength as
steel products3) It has more tenacity, it will not brake into pieces
4) Suitable for any temperature (put it into oven at 60 centigrade for 16 hours,
then put it into cold
storage at -40 centigrade for 2 hours, the features of it
will not be changed)
5) Less noise when
cars or
trucks go by
6) Different colors available
7) Temperature endurance: put sample into oven at 60 centigrade for 16 hours,
then put it into cold
storage at -40 centigrade for 2 hours, the result is: expand
rate: ≤0.2%; shrink rate: ≤0.09%
8) Anti causticity: under usual temperature, puts it into liquid with rust material
for 2 hours, the result is: no chap, no expand
and no blanch on surface
9) Friction modulus: grits lid with its base directly for 5 hours, modulus is ≥0.35
10) Anti aging: puts it into a temperature
and wet equipment, uses Xenon
light at
60 centigrade ±≥5 centigrade
and rain for 500 hours
and its anti
refraction strength is ≥3
