brief introduction
graphene nanoribbon
Graphite cloth is a kind of antifriction material developed in China on the basis of foreign samples on 90s, because of the widespread use of sander. It is also called carbon cloth abroad, and is also called Graphite Ribbon and graphite band in china.
Graphite cloth is a simple process, manual production began, after years of research and development has become a clear classification, application of mature products, at present, can replace foreign products, and have been exported abroad.
classification
Graphite cloth, as a solid lubricating material, with blankets and temperature resistant foam pad applied to the sanding machine, to reduce friction between the steel plate and the belt sander sanding belt protection, improve the quality of.
Can be divided into: GC and HD, ultra-thin, backing, self-adhesive type.
Type GC and type HD
GC graphite cloth Graphite, Coated, Canvas - Standard, Type (GC) is the main raw material using 99.99% natural flake graphite. Flake graphite is dipped in coated liquid glue (which makes it easier to immerse graphite scale after heating), enters water, solidifies, dries, and finally cuts into customer size. GC graphite cloth has high lubricity, and is suitable for all kinds of light ordinary sanding machines.
The characteristics of GC type of stone Mobu:
In the selection of graphite, GC graphite cloth all use lubricating best natural flake graphite, with flexible glue, made into a flexible graphite coating and lubrication, good cheap, can apply to various sanding machine, compared with heavy graphite cloth, only used in the heavy sanding machine, because heat resistance is weak, so life is short.
HD type
HD graphite cloth Graphite, Coated, Canvas - Heavy, Duty (HD) is the main raw material using solid graphite particles and 99.99% natural flake graphite. First, the adhesive is applied on the base cloth, and the graphite particles are permeated into the adhesive by extrusion to dry. The final cut is made to the size required by the customer. HD graphite cloth has a strong abrasion resistance, and high temperature resistance, long service life, suitable for sanding, particleboard, MDF heavy sanding machine.
The friction coefficient of HD graphite cloth is GC type graphite cloth, therefore, does not recommend the use of ordinary sand machine type HD graphite cloth.
The characteristics of HD type of stone Mobu:
In the selection of graphite materials, using the technology of flake graphite and graphite particle composite, graphite particles due to expensive and complex production process is difficult, so the cost is high, the high price of the HD graphite cloth, HD graphite cloth in the production process, the use of high temperature resistance and higher bonding strength of glue, therefore, this type of the product is especially suitable for heavy sanding machine, also can be applied to other kinds of sanding machine.
Ultra-thin
Ultra-thin stone Mobu is mainly applied to the requirements of sanding surface finish.
Backing adhesive type
Backing adhesive is mainly used in simple flat sander.

Carbon Fiber Cloth
According to the carbon fiber material , carbon fiber cloth can be divided into: PAN based carbon fiber cloth, rayon based carbon fiber cloth and pitch based carbon fiber cloth, wherein PAN based carbon fiber cloth accounted for more than 90% of the market, so we talk about PAN based carbon fiber cloth mainly.
In accordance with the specifications of carbon fiber cloth, it can be divided into: 1K carbon fiber cloth, 3K carbon fiber cloth, 6K carbon fiber cloth, 12K carbon fiber cloth, 24K and above large tow carbon fiber cloth, the number of single carbon fiber tow, 1K=1000 (root), 3K=3000 (root), 6K=6000 (root), 12K=12000 (root).
Carbon fiber cloth according to the woven pattern, it can be divided into: plain weave, twill, satin, the former two are the most common.
The plain carbon fiber cloth, the characteristics of plain weave is the warp and the weft up and down according to the rule of interleaving. The plain fabric density can not be too high, relatively thin, good wear resistance, good air permeability, and it is opposite the same cloth uniform. The fiber bundle of the carbon fiber cloth has been in a state of ups and downs, the bending point of the fiber is more, and the elongation at break is higher in the process of drawing.
The twill carbon fiber cloth , the twill weave fabric has the diagonal lines with a certain angle with the fiber arrangement direction, the ridge orientation does not exist on the fiber bundle, but because fiber warp knitting, warp or weft fibers over two zonal or meridional fibers in knitting. This kind of diagonal appearance has a very strong sense of three-dimensional, it is used to make car modification products, such as panels, hood, exhaust tube, etc.
The satin carbon fiber cloth, the satin weave has separate, discrete by interlacing points (or weft intersection points) evenly distributed regularly in the organization in circulation, this form is called satin weave. This kind of weaving structure makes the fabric density higher, so the fiber cloth is more thick. This satin cloth surface is smooth, even, soft, shiny or slightly lower than the strength of grain, plain and twill.
