The manufacturing method of basic metal-wound gasket consumption process, the present creation discloses a tooth-shaped gasket consumption process, comprising the following process: mixing rubber, graphite powder and accelerator in a 5:2:2 weight formulation of equal value; putting the mixture into the mould, then putting it into the heating furnace with the mould, entering the furnace temperature control below 200°C, raising the temperature to 500°C and insisting on 3-4 hours.


The shaped metal wound gasket continues to be heated up to 1200-13000°C and adhered to for 2-4 hours, the furnace is cooled to 750°C and the stable heat treatment in argon environment is stopped; the pressed sheet is removed and placed in the vulcanising machine at a temperature of 300-350°C in conditions of rolling sulphur for 30-40 minutes; after removal the dip washing is terminated with tap water and then the drying is terminated with induced air equipment. The gasket consumed by this manufacture is not easy to be damaged and is strong and durable.


This creation touches the sealing material range, in detail, especially touches a kind of metal tooth-shaped gasket with outer ring consumption process, sealing material cited is to be able to accept the seam offset in order to reach the air-tight, water-tight purpose and placed in the building seam material called sealing material. Sealing materials include metal materials (aluminum, lead, indium, stainless steel, etc.) Non-metallic materials (rubber, plastic, porcelain, graphite, etc.) The most common materials used are rubber-based elastomers and elastomers.


However, it is the rubber-based elastomer materials that are used more often. The existing gasket fibers are not high in wear resistance and corrosion resistance, weak in flexibility, and the consumed gaskets are not resistant to wear and tear and have a short service life. In order to solve the above problems, the purpose of this creation is to solve the deficiencies in the prior art and provide a tooth-shaped gasket consumption process
