Mould On Tires Mechanical Cleaning

Jun 24, 2016

Molds are an important tool used in tire vulcanization. Mould on Tires During the course of use, the mold is inevitably subjected to the integrated deposition of the release agent (main pollutants such as sulfide, 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, 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, Mould on Tires widely used by the tire industry. The method has the advantages of simple and easy operation, 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, Stomatal work is very large; must be removable mold, resulting in high labor intensity, long cleaning cycle.

Chemical cleaning methods include: 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; the same time, these pharmaceutical raw materials pollute the environment, damage the health of operators, must have a complete means of labor insurance and pollutants Processing equipment. At present, the law is mainly used for small rubber products business.

With the continuous development of science and technology, Mould on Tires 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, 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 technology in many fields with its own many advantages.

Laser cleaning technology refers to the use of high-energy laser beam irradiation surface of the workpiece, so that the surface of the dirt, rust or coating instantaneous evaporation or stripping, high-speed and effective cleaning surface cleaning objects or surface coating, so as to achieve a clean process. It is a new technology based on the interaction between laser and material. Mould on Tires Unlike traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning (wet cleaning), it does not require any organic solvent that destroys the ozone layer, No noise, harmless to the human body and the environment, is a "green" cleaning technology.

Laser cleaning uses a clean substrate (also known as the parent) and the surface attachment (dirt) for a certain wavelength of laser energy, with a very different absorption coefficient. Radiation to the surface of the laser energy, most of the surface attached to the absorption, Mould on Tires so that heat or vaporization evaporation, or instantaneous expansion, and by the surface of the steam flow to drive, from the surface of the object, to clean the purpose.

(Sulfur, inorganic oxide, silicone oil, carbon black, etc.) to absorb a lot of energy, is instantaneous expansion, Vaporization, away from the mold surface, so as to achieve the effect of cleaning.
