Molds are an important tool used in tire vulcanization. During the course of use, the mold is inevitably subjected to the integrated deposition of the release agent (main pollutants such as sulfide, Mould on Tires inorganic oxide, silicone oil, carbon black, etc.) of the rubber, Mould on Tires the compounding agent and the releasing agent used in the vulcanization process. Causing some pattern of pollution dead zone. Therefore, Mould on Tires the mold must be regularly cleaned to ensure the cleanliness of the surface in order to ensure the quality of the tire and die life. In view of this, tire mold cleaning technology development has been the industry's attention.
The use of artificial sand or steel wire physical grinding and dry sandblasting, according to the need to use a different combination of cleaning. Mechanical cleaning method is a mature technology, widely used by the tire industry. The method has the advantages of simple and easy operation, Mould on Tires but it can not overcome the defects: it will cause mechanical damage to the mold, shorten the life of the mold; sandblasting is easy to plug the mold exhaust hole, Mould on Tires Stomatal work is very large; Mould on Tires must be removable mold, resulting in high labor intensity, long cleaning cycle.
Chemical cleaning method mainly includes: organic solvent method, melting method, pickling method, alkali washing method.
These methods are easy to use, low cost, Mould on Tires but long-term use of the above method will cause mold corrosion, which directly affect the appearance and quality of the product; Mould on Tires the same time, Mould on Tires these pharmaceutical raw materials pollute the environment, damage the health of operators, must have a complete means of labor insurance and pollutants Processing equipment. Mould on Tires At present, the law is mainly used for small rubber products business.
With the continuous development of science and technology, some new technologies have been developed and applied. These cleaning techniques will bring "revolution" to the tire mill industry that is of concern. But these high investment technology can be accepted by the market, Mould on Tires need to be tested.
Laser cleaning technology is a new type of cleaning technology that has been developing rapidly in the past 10 years. It has gradually replaced the traditional cleaning process in many fields with many of its own advantages.
Laser cleaning technology refers to the use of high-energy laser beam irradiation of the surface of the workpiece, so that the surface of the dirt, rust or coating instantaneous evaporation or stripping, Mould on Tires high-speed removal of surface cleaning objects or surface coating, Mould on Tires so as to achieve a clean process. It is a new technology based on the interaction between laser and material. Unlike conventional mechanical cleaning, chemical cleaning and ultrasonic cleaning (wet cleaning), it does not require any organic solvents that destroy the ozone layer, No noise, harmless to the human body and the environment, Mould on Tires is a "green" cleaning technology.
Laser cleaning uses a clean substrate (also known as the parent) and a surface attachment (dirt) for a certain wavelength of laser energy, with a very different absorption coefficient. Mould on Tires Radiation to the surface of the laser energy, most of the surface attached to the absorption, so that the heat or vaporization evaporation, or instantaneous expansion, and by the surface of the steam flow to drive, Mould on Tires from the surface of the object to achieve the purpose of cleaning.
