After the printing plate processor is used for a period of time, the internal liquid tank is prone to crystallization and scale formation. This is particularly likely to happen when the water quality is relatively hard. This situation is obviously much better than the previous film processor, but as a tool, during use, it will always require maintenance over time. How to carry out the internal cleaning of the printing plater, the correct method should be like this: Whether it is the basic equipment such as printing plateetters, or other advanced equipment, such as color Doppler imager, C-arm X-ray machine, medical film printer, etc., routine maintenance has conventional methods and professional methods. distinguish. The conventional method of handling crystals inside the plate processor is to rinse with dilute hydrochloric acid. The advantage of this method is that it is easy to operate, and the decalcification effect is thorough; however, the disadvantages are also very obvious: a hydrochloric acid odor stimuli, and second, hydrochloric acid is a strong acid, which easily causes corrosion to the equipment. This is because the conventional method is actually ridiculously scientific, so we are gradually discarding it, and we recommend that customers use more specialized maintenance methods and use special cleaning agents. Diluted the concentrate with water, put it into the developing machine tank and heated it to 30°C, and turned it on for 30 minutes to clean the surface of the colloidal roller crystals in the plate processor, the crystallization of the inside wall of the drug tank, etc., and it is not corrosive. Others include advanced equipment such as color Doppler imager, C-arm X-ray machine, medical film printer, etc. Manufacturers are actively guiding customers to adopt new methods for maintenance, helping to extend the service life of equipment and reduce the cost of customers. It also laid a good foundation for further cooperation between the two parties.
