Sanding Belt
Abrasive
belt is a belt-shaped tool that can be ground and polished, which is made by
bonding abrasives to flexible materials such as paper and cloth with a binder.
It is a main form of coated abrasives. Its basic composition is: base material,
abrasive and binder, collectively called the three elements of abrasive belt.
Abrasive belt is the main tool of the sanding process. Abrasive belt grinding
is a soft grinding method, which is a compound processing abrasive tool with
multiple functions of grinding, grinding and polishing.
Abrasive
tools are tools for grinding, grinding and polishing. Most of the abrasives are
artificial abrasives made of abrasives and bonding agents, and natural
abrasives are also directly processed from natural ore. In addition to being
widely used in machinery manufacturing and other metal processing industries,
abrasive tools are also used in the processing of non-metallic materials such
as food processing, paper industry and ceramics, glass, stone, plastic, rubber,
and wood.
Abrasives
are divided into natural abrasives and artificial abrasives. All materials that
can be used for grinding or grinding in nature are collectively referred to as
natural abrasives.
Natural
abrasives mainly include: natural corundum and garnet
Artificial
abrasives mainly include: white corundum, brown corundum, silicon carbide,
zirconium corundum, synthetic diamond, cubic boron nitride.
How
to choose a suitable abrasive belt and further improve the smoothness and
flatness of sanding is a very important issue in the use of abrasive belts. Due
to the differences in the three major components of abrasive belts and various
characteristic factors, abrasive belts can be divided into many varieties
according to different grinding objects, grinding conditions and grinding
requirements. The following is the classification of abrasive belts according
to abrasives. Different abrasive belts are suitable for different products. The
following types of belt operations are: automatic grinding, mechanical hand
grinding, desktop grinding, and manual tool grinding.
Types
of abrasive belts (according to abrasives):
1:
Accumulated abrasive belt
Application:
Widely used in polishing various non-alloy, low-alloy and high-alloy steel,
stainless steel, brass, bronze and other non-ferrous metals. Good
self-sharpening, long service life, uniform grinding volume and uniform surface
roughness.
2.
Brown corundum belt
Application:
Widely used in metallurgy, machinery, shipbuilding, wood, building materials,
textile printing and dyeing industries. Grinding and polishing of bamboo and
wood products, decorative panels, stainless steel, non-ferrous metals and other
complex surfaces. Fast cutting, heat resistance, long service life, efficient
wear resistance.
3.
Ceramic abrasive belt
Application:
Widely used in grinding chromium steel, chromium-nickel steel, stainless steel,
high-alloy steel, nickel-based alloy, titanium alloy, brass and bronze, etc.,
with good self-sharpening, strong grinding, and large removal of grinding
materials.
4.
Silicon carbide belt
Application:
Widely used in the grinding and polishing of brass, bronze, titanium alloy,
aluminum alloy, glass, ceramics, minerals, stone, rubber, and synthetic
materials. The sand surface is sharp, with very high strength and grinding
ability, suitable for grinding medium and high density plates. The bucky has
strong tension and ultra-wide sub-tension, which can be used for ultra-large
abrasive belts.
5.
Zirconium corundum abrasive belt
Application:
Widely used in the grinding and polishing of steel, alloy steel, cast iron and
non-ferrous metals, medium load or heavy load powerful grinding. The rigid
polyester fabric is resistant to strong tension and impact, has high abrasion
resistance, and has excellent comprehensive cost performance.

Recently, Chongqing Boao Mg-Al Metal Manufacturing Co., Ltd. has issued 6 containers to Europe and other places.
In the container, there are Volvo's middle control parts, Ford's instrument panel, Chrysler's support frame, Nissan's front water tank bar, and the steering wheel of the 43 global cars. They are exclusively provided by Boo!
The person in charge of the Chongqing Municipal Science and Technology Commission said: With Boao and other enterprises as representatives, Chongqing's traditional advantageous industries have begun to transform from "manufactured in Chongqing" to "created in Chongqing".
From monograph production to independent design of world-famous auto giants, why did they not co-opt with Boao?
The answer is: These "Chongqing made" magnesium alloy products are not only light weight, good performance, and the cost is only 1/3 of similar products.
It is understood that as early as 2005 or so, new materials for magnesium alloys in Chongqing were born. Although the application of magnesium alloys in the international market was already alive and well, it was still a new thing in the domestic market, so it was either a "hardware." Such as low-grade products, or simply follow the production, for the local motorcycle supporting the simple replacement of parts and components.
