Italian research found that spiders spraying carbon materials can spit out super spider silk

Italian researchers have discovered that spraying ordinary carbon nanotubes with carbon nanomaterials can produce super strong filaments that are 3.5 times stronger than the most known spider silk.

Nicholas Pugno of the University of Trento and his team collected 15 spiders, which sprayed 5 of them a mixture of graphene and water, and 10 of them used carbon nanotubes and water. The mixture was sprayed and used as a comparison group to observe the effects of the two materials. If you are concerned that the nanomaterial coating will threaten the life of the spider, you are right - four of the spiders will die immediately. Among the surviving spiders, several of the spit silks were of poor quality, while others briefly spit out the silk containing the spray material after a short adjustment. These cobwebs, which are infused with carbon, are super tough, and the silk spit from a spider sprayed with carbon nanotubes is stronger than the current silkworm toughness record holder. 3.5 times.

In theory, when a spider is silking, it will find suitable materials (whether eaten or absorbed) from the environment, and people can control the texture of the spider silk by controlling the external environment. Researchers don't know which form of graphene and carbon nanotubes are incorporated into the spider silk, but the carbon-containing spider silk is actually produced from the spider's belly. One possibility is that the carbon is wrapped directly on the outside of the wire, but Pugno believes that it is not enough to enhance the toughness of the wire. Instead, he firmly believes that spiders sweep the material in the environment and incorporate it into the spider silk during the silking process.

Limited experience means that follow-up research and replication activities are based on well-defined mechanisms. Researchers believe that this super-strong spider silk can only be produced in small batches, and the specific use is still unknown, but "this method can be extended to other animals and plants, which can lead to a new class of biomimetic materials. application".

Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).

Main use of graphite

Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.

Graphite classification

1. Raw and broken. It is a raw blank that is not qualified after molding.

2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.

3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
