The electronics industry is the largest user of ODS solvents. Many vacuum electronic components, small and micro-precision metal parts are cleaned and degreased (degreased) using TCA, CFC-113, CCl4 and other ODS solvents, which not only endanger the health of operators, but also destroy the atmospheric ozone layer , Causing great harm to human living environment, so seeking high-precision cleaning technology to replace ODS has become an urgent task at present. To this end, we designed a set of control system that combines PLC, human-machine interface and intelligent control module to replace the non-ODS water agent cleaning machine application of TCA degreasing process according to the cleaning process characteristics of pins and anode caps for CPT / CDT. Control system function The concentration, working temperature and cleaning time of the liquid cleaning solution are important technical parameters of the non-ODS liquid cleaning process.
Considering the technical requirements of anode caps and pins for CPT / CDT and the process flow of water agent cleaning, we require the control system to have the following functions: (1) Automatic compensation of cleaning solution concentration (automatic addition of cleaning agent) function. The cleaning agent (concentrate) and deionized water can be added automatically according to the concentration set by the process to ensure the concentration required by the process. (2) Automatic temperature control function of each process tank. The heating system can be started or interrupted according to the process temperature setting. When the temperature ≤ the set process temperature lower limit or ≥ the process temperature upper limit, the cleaning system cannot enter automatic operation. (3) The automatic control function of the cleaning time (operating program and time of the robot arm), set the rotating speed of the basket according to the cleaning process requirements, the program and time of the robot arm lifting, lowering, left and right running. ) In the tank, the ultrasonic generator starts at the same time. (4) Automatic control function of rinsing water flow rate and resistivity. Determine the flow rate of countercurrent rinsing water (pure water) according to the requirements. When the water quality (resistivity) and flow rate do not meet the process requirements, the system will alarm and stop automatic operation. (5) The setting, modification and parameter storage function of each technological parameter.
Filter mesh refers to small aperture metal mesh or other materials with smaller apertures for a variety of different filtration, dust removal and separation requirements. They are widely used in shower panel, sanitary pipe systems, purifiers, electronic components, to remove contaminants or in applications, such as coffee machine, soya milk machine, to extract a filter cake. Because the metal mesh filters are one of the most durable filter media available, the material is mainly made of copper, iron, steel, nickel, stainless steel, alloy. It is acid resistant, alkali resistant, temperature resistant and wear resistant.
We customize diverse patterns metal microporous mesh with drawings provided by customers. We are equipped with professional metal etching equipment and exposure development equipment. Chemical metal etching filter mesh is a double-sided and simultaneous processing technology, which can make the product surface (positive and negative) smooth, without bumps, pits, burrs, warps, and flat mesh without deformation. Below are the advantages for customized metal filter mesh:
Flow Rate
One of the most significant advantages metal mesh has over most filter media used today is its ability to deliver an adequate flow rate. This is achievable as the wire diameter and mesh opening can be customized to perfectly match the contaminants you are filtering out, providing you with an enhanced level of filtration surface area.
Durability
300 series stainless steel is predominantly used. This helps create a filter that can withstand a wide range of impurities, pressure variations, and extreme temperatures without hindering the filter's accuracy. In addition, stainless steel is a very pliable material, allowing the filter to be formed to fit your filter system and hold its shape after several uses.
Accuracy
The weaving process used to construct mesh filters is heavily monitored from start to finish. As a result, the pore openings of the filter are exact and uniform throughout the filter. These precise pore opinings ensure that the end product, whether a filtered substance or a filter cake, is consistent and complies with industry standards.
Clean ability
As metal mesh features accurate pore openings, blinding and plugging are significantly reduced. This, combined with the enhanced flow rate, means system operators can clean the metal mesh easily. These two properties allow the mesh filter to be backflushed and purged of any unwanted debris with minimal pressure.
