Mould on Tires Long Cleaning cycle

Yantai Wonray Rubber Tyre Co.,Ltd | Updated: Nov 06, 2017

The use of manual emery cloth or steel wire physical grinding and dry sandblasting, Mould on Tires according to the need to choose different combinations of cleaning.

Mechanical cleaning method is a mature technology, Mould on Tires widely used in tire industry. The method is simple and convenient for the equipment, tool requirements are not high, but there are insurmountable defects: the mold will cause mechanical damage, shorten the die life; Mould on Tires sandblasting treatment easy to plug the mold of the exhaust hole, sandblasting after cleaning the exhaust hole of the workload is very large;

Laser cleaning technology, a new cleaning technology developed rapidly in recent 10 years, has gradually replaced traditional cleaning technology in many fields with many advantages.

Laser cleaning technology refers to the use of high-energy laser beam irradiation on the workpiece surface, so that the surface of dirt, rust or coating occurs instantly evaporation or stripping, high-speed and effective cleaning object surface attachment or surface coating, Mould on Tires so as to achieve a clean process.

It is a new technology based on the interaction effect of laser and matter, unlike traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning (wet cleaning process), it does not require any organic solvents that destroy the ozone layer, no pollution, no noise, Mould on Tires no harm to human body and environment, and is a kind of green cleaning technology.

Laser cleaning in the mechanism of its use in the mold cleaning, is to use a clean substrate (also known as the matrix) and surface attachment (dirt) to a wavelength of laser energy has a significant difference in absorption coefficient. The laser energy radiated to the surface is absorbed by the surface attachment, Mould on Tires which is heated or vaporized, or instantaneously inflated, and is driven by the steam flow formed by the surface, which is removed from the surface of the object and achieves the cleaning purpose.

Specifically for the tire mold cleaning, the mold absorbs the specific wavelength of the laser, the energy is very small, will not cause damage, mold surface dirt (sulfide, Mould on Tires inorganic oxides, silicone oil, carbon black, etc.) absorb a large amount of energy, be instantaneous expansion, vaporization evaporation, with the surface of the mold, so as to achieve

Dry Ice cleaning technology is a dry ice hockey granule that is made into a certain size (2-14mm diameter) by a liquid CO2 through a dry ice preparation machine (Granulator). Mould on Tires With compressed air as a power source, the dry ice hockey particles are sprayed on the surface of the cleaned object at a higher speed through a jet cleaning machine, which is similar to the principle of sandblasting process. Dry ice particles not only on the surface of the dirt grinding, impact, and more importantly, the low-temperature effect of dry ice particles and sublimation of the dirt quickly frozen brittle, and its contact with the material produced by different cold contraction effect,Mould on Tires so that the dirt reduces the surface of the material adhesion, coupled with the grinding and impact of dry ice particles, Compressed air blowing sweep cut, so that dirt from the cleaned surface in solid form was stripped, to achieve the purpose of cleaning dirt.
