Film slitter blade selection material change

In recent years, the emergence of ceramic knives, which are made from a nanomaterial called zirconia, has begun to transform the way people think about cutting tools. After being calcined at high temperature and polished by diamond, it becomes the finished ceramic knife.

As the product of modern high technology, ceramic blade has the advantages that traditional metal cutting tools can not compare with. It is a new type of blade made by high-tech nanotechnology, and its sharpness is more than ten times that of steel knife. Therefore, ceramic knife has the characteristics of high hardness, high density, high temperature resistance, magnetization, oxidation resistance and so on.

Nowadays, in many industries, ceramic knife is used, such as the film industry, ceramic splaying blade is used to complete the splaying of the film. You must know that the film is a product with strong toughness and compression resistance. Generally, it takes a long time to pull it off, and after tearing, the face of the product is completely different. It is very ugly, so it is necessary to carefully consider how to cut the film.

The emergence of thin film cutting blade soon occupied the film cutting industry, because the blade is fast enough, sharp enough, can quickly achieve the cutting, this is the film cutting effect.

This blade belongs to one of the ceramic knives. Because of its high quality performance, it has been widely used in recent years. Many businesses will produce it, leading to a mixed ceramic knife market.

First, look at the blade: high quality ceramic knife blade line bright fine, uniform and consistent. The cutting line of the ceramic knife with low quality is thick and wide, uneven and discontinuous.

Two, look at the details: the real ceramic knife pays great attention to the details, in its back, tip, head have been carefully polished and rounded treatment, effectively avoid the use of hand injury phenomenon.

Three, look at the surface: high-quality ceramic knife surface is smooth, its light can be seen, no defects, fine grain, comfortable feel, high toughness, thick blade. Poor quality ceramic knife surface stains, gray spots, cracks, pinholes, feel rough, the blade is thin.
