What is the role of industrial chillers in the vacuum coating process? Vacuum coating works at a high temperature membrane surface evaporation falling crystals. As the air for evaporation of the membrane molecules will produce resistance caused by collision to make crystals become rough dull, it must be under high vacuum in order to make fine crystal bright, if not high vacuum will lose luster crystal bonding force is very poor. Early vacuum coating is to rely on natural evaporation body scattering, combined with low gloss poor poor ergonomics. Now add frequency magnetron sputtering target magnetron target shooting film of precursor molecules will evaporate under the influence of an electric field to accelerate the bombardment target, a large number of target atoms sputtered, neutral target atoms (or molecules) is deposited a film on the substrate, can not be solved in the past natural evaporation process of membrane species, such as titanium zirconium oxide and the like. IF equipment cooling water must be added, because of its high frequency current is large. Currents flowing in a conductor skin effect, the charge will be gathered in the conductance have surface area, so that the conductance heat pipes do so using the hole conductors middle water cooling. (Mainly cylindrical target) Why should water cooling? Magnetron sputtering target at launch will generate heat will deform a gun, so it has a water jacket for cooling a gun. At the same time there is an important reason may magnetron sputtering coating technology is considered one of the most prominent achievements. It sputtering rate, the substrate temperature is low, the film - substrate with good adhesion. From a deeper study the movement of electrons in a non-uniform electromagnetic field and to explore the more general principle of magnetron sputtering and transverse magnetic field inhomogeneity and symmetry is the essential reason for magnetic confinement. Magnetron sputtering coating can be considered one of the most outstanding achievements of technology. It sputtering rate, the substrate temperature is low, the film - a good base bonding force, stable performance of the device. Protection of open industrial chillers: protection system devices are: compressor delay start protection, overload protection, high and low voltage protection, temperature control switches, antifreeze switch, fuse plug, electronic time protect the safety valve, compressor overheating protection, compressor frequent start protection and abnormal indicators, to ensure the normal operation of the unit. Open chiller control system: the company has developed intelligent PLC, PC class computer control system, can do remote monitoring and control, with automatic loading and unloading, the timer switch and record the cause multiple functions; simple, host and power supply connection. Low failure rate, high safety factor, simple installation, system control instantly adjusts, intuitive and reliable. Hot and cold machine using the main features of the highest in Europe and America imported compressor head brass welding method using anaerobic heating power switching function RS485 communication function for automated management (optional) electrical use OMRON, FUJI, TE, LG, MOELLER, ABB temperature control range: water temperature + 5oC-98oC stainless steel integrated pipelines for less pipe resistance and rust using imported components, life is long control mode: imported for the computer or PLC (optional) Perfect safety protection, fault indication, maintenance, maintenance without professional high efficiency evaporator, can save more energy than 30% C-10 uses two compressors used independently or together.
