1st line add another national invention patent

Recently, the process and device of multi-point positioning method for repairing worn shaft of 1st line company obtained national invention patent certificate. Up to now, 1st line company has obtained 11 national invention technology patents, and is in the leading position of polymer composite technology application, innovation and development.

At present, traditional repair methods for shaft wear in China mainly include welding, electric-brush plating, thermal spraying and other technologies. These technologies are often inadequate when facing to complex working conditions, with long repair cycle and high cost. At the same time, it is easy to cause parts deformation or fracture, resulting in serious waste of various resources of the enterprise, which is not conducive to enterprise healthy development.

Multi-point positioning method repairing technology developed by is 1st line company and increasingly improve new repair technology, which principle is use of polymer composite materials make its permeability formation of intermolecular forces and repair parts form excellent adhesion, through the multi-point positioning method can realize online repair of wear & tear, improve service life of the equipment. Meanwhile, repair shaft surface and bearing contact close to 100%, which can better to carry equipment run time in all kinds of forces ,this technology  make up makes up the fact that traditional repair method unable to carry out on-site repair and has strong limitations. It improves equipment repair efficiency, extends the service life of the equipment, and greatly reduces the impact of equipment loss on the enterprise.

In recent years, 1st line company timely adjust, improve and develop a number of technology(such as metal forming intelligent spray system, mould positioning repair method, protective coating composite organic coating, hand mould protective coating, scale cleaner) intent to insufficient during equipment repair process, and apply in steel, cement, manufacturing, machinery and other fields, These patent technological achievements not only enhance the core competitiveness of fortune 1st line technology and provide technical support for company development, but also become a source of power for fortune 1st line to build a scientific and technological innovation group and set foot in the emerging technology industry.

1ST Line new Polymer coating successfully solved high temperature corrosion resistance problem of rotary kiln

Recently, application of new type polymer coating successfully solved high temperature alumina rotary kiln outer wall surface corrosion problem in the high temperature corrosion field. This coating technology has excellent adhesion and corrosion resistance, can be applied in the rotary kiln and the sink surface, especially quick repair corrosion damage of weld parts, greatly improve  rotary kiln corrosion resistance.

The high temperature alumina rotary kiln is made from rolled steel sheet and welded automatically. The cooling device of rotary kiln is circulating cooling water, which is directly sprayed on the surface of kiln body with the temperature over 200 degrees. Long-term spraying operation results in rusting corrosion on the surface of kiln body, thickening rust layer, reduction heat exchange efficiency, thinning kiln walls and shortening equipment service , causing hidden trouble to safety production. However, traditional repair process has no effective solution to deal with this problem, so the whole equipment can only be replaced, which increases maintenance cost.

The successful application of this technology provide a good guarantee for high temperature alumina high quality production provides a good guarantee. So 1st line anti-corrosion technology under high temperature further enhance. The superiority and professional of 1st line polymer technology has been well known by various industrial enterprises, and provide service many years for chemical, oil, manufacturing, rubber, etc an-ti corrosion field. 1st line will continue to carry out product research and development through our own scientific research strength, and integrate the world’s cutting-edge technologies to benefit domestic industry long-term development.
