I. Overview: The salt spray test is specially designed for the surface of various materials. After the anti-corrosion treatment of paint, coating, electroplating, anodizing, anti-rust oil, etc., the corrosion resistance of the product is tested. It is widely used in hardware, electroplating, electronics, chemical, automotive, aerospace, aerospace, communications and other industries to simulate the corrosion of marine materials in the materials and coatings of the products, so as to analyze the performance of the samples under specific environmental conditions. And evaluation. Second, touch screen salt spray machine properties: 1 , characteristics: 1. The local control system is controlled by a 6.5-inch LCD touch screen, and the screen display is beautiful and clear. 2, all digital circuit design, temperature control for PID automatic calculation , temperature accuracy to 0.1 °C, continuous   Touch more than 200,000 times , the test function is complete. 3, the work interface dynamic display, using the man-machine dialogue interface, and there is a buzzer alarm to indicate the working condition. 4. The instrument adopts ergonomic design, beautiful appearance and convenient operation. 5. Regardless of the lack of water in the test room or pressure tank, the water level at the corresponding position will be automatically added to ensure the experiment.   Continuous, reliable and safe. 6. When the water level in the laboratory is replenished, the delay water replenishment function will be activated, and the automatic water inlet valve will      The laboratory is supplemented with water for 6 to 10 seconds to prevent frequent activation of the electronic valve due to water consumption.      Extend the working life of the electronic valve.    7, intelligent over-temperature protection system, when the test chamber exceeds the set temperature or the pressure tank 5 ℃, dynamic touchscreen       Prompt, and will automatically cut off the circuit, the heating tube is no longer powered, 8, with power-off time memory function, if the instrument suddenly power off or directly shut down in the middle, salt spray machine       After the power is turned back on, the last tested data and setting data will be retained, and will not cause the test.       The waste between them will save the operator a lot of time and effort. 9 , precision glass nozzle (PYREX) 5000 hours to ensure no crystal blockage. 10 , with double over-temperature protection, on the basis of the touch screen over-temperature protection, we also installed the laboratory       An EGO (over temperature protection device) to ensure that even in the worst case, the machine can still be safe       Fully stable . 11, the test cell with titanium heating tube is heated, its corrosion resistance of stainless steel heat pipe is 8       Up to 10 times or more, the steam directly enters the test chamber, and the heating rate is fast, and the standby time is shortened. 1 2 , spray tower conical dispersion, with guiding fog, adjust the amount of fog and even fog. 1 3 Compared with the ordinary salt spray machine, all the function keys of the touch screen salt spray machine are integrated on the screen, which makes the operation more convenient. All lines adopt integrated circuit and modular structure, which greatly reduces the incidence of failure. 1 4 , when the time is set, when the temperature and water level reach the setting requirements, the spray will be started automatically, without manual guard. 15. Innovative lock screen function, the operator can lock the screen when leaving, to prevent unrelated operators from mishandling the test. 16. The second-generation touch screen of Jingzhuo Instrument further enhances the treatment of waterproof and anti-fog. 17. Jingzhuo Instrument is the direct development manufacturer of this touch screen, and masters the complete core technology of touch screen. 2, the use of materials: Laboratory: A grade PVC gray impact plate, thickness 5mm, and three-dimensional reinforcement technology, the machine structure is more firm. Constant temperature water bath: The A-level gray PVC impact resistance plate, a thickness of 5mm, along with automatic water level control, eliminating the inconvenience of artificial water. Laboratory cover: transparent acrylic, thickness 5mm Reagent filling bucket: concealed design, PVC gray impact resistant board, thickness 5mm, integrated with the appearance of the machine. Laboratory rack: A grade A PVC gray impact resistant board can be used. ~30. The angle can be adjusted at will (the machine rack can be loaded with heavy objects and can be customized according to customer needs). Saturated air bucket: It is pressed and molded with imported PVC plate and equipped with automatic water level controller, which is inconvenient for artificial water addition. Large base: Concealed design to avoid dripping salt water corrosion and neat appearance. Salt spray collection cup: The hidden design can effectively avoid the damage of the glass measuring cup caused by accidental touch . 3, the use of temperature: According to the standard parameters such as CNS, JIS, ASTM, etc.: Brine test method:  1. Laboratory: 35. C+1. C        2. Saturated air bucket: 47. C+1. C Third, the structure of the introduction: 1 , touch screen panel map: Note: 1. Actual laboratory temperature: This is the actual temperature of the heating tube heating laboratory. The current temperature is automatically recorded and cannot be adjusted. 2 , set the temperature: each bit can be adjusted, use a finger to press one of the numbers, when the number is flashing, you can use the lower right arrow to adjust the temperature required for the experiment. 3 , the time required for the experiment: can not be adjusted, record the time spent in the current experiment. 4 , set time: adjustable, set according to the experiment, the setting method is the same as the set temperature. 5 , test cumulative time: can not be adjusted, record the total use time of this machine. 6. Pressure tank temperature: It cannot be adjusted and changes according to the temperature inside the pressure tank. 7. Pressure barrel setting temperature: It can be adjusted. The adjustment method is the same as above. According to the actual test setting, please set the setting too high. Refer to “Usage Temperature†for details. 8 , spray accumulation time: adjustable, only record the spray time. 9. Time to stop accumulation in the middle: adjustable, used for cycle test, such as spraying for 5 hours, stopping for 1 hour, the spray time is set to 5 , and the fog stop time is set to 1 . 10 , laboratory water level: When the laboratory is short of water, this mark will flash, if there is an automatic water inlet pipe, then the water will automatically start to increase until the flashing stops. 11. Brine room water level: When the salt water chamber is short of water, this mark will flash. At this time, it is necessary to manually add appropriate amount of salt water to the salt water tank. The flash will stop soon. 12 , pressure tank water level: When the pressure tank is short of water, this mark will flash, when the automatic water is added, the water switch will be automatically turned on, or you can manually add water until the mark stops flashing. 13. Switch on and off: Press and hold this button for 5 seconds, the machine will start. Press and hold the switch button for 5 seconds, the machine will stop running. 14. Work pause: press this button, the spray will pause, the actual test time and spray time will be suspended, long press this button to clear the actual test time. If the set time, press this button, when the temperature reaches the set requirements, the machine will automatically sprayed. 15. Spray pause: Press this button , the spray will pause, but the actual test time and spray time will not be suspended. 16. Defogging: Press this button to defogg the laboratory and the spray stops. 17. Adjust button: When the desired adjustment number is flashing, the up and down arrows are used to adjust the flashing digital size; at the same time, press the two buttons 2S to lock the screen to prevent the person from accidentally pressing when leaving. Welcome to inquire: There are many ways to design stone carvings, among which the sink carving, also known as "line carving", is an artwork using the "water mill sink flower" carving method. This kind of carving method absorbs traditional techniques such as Chinese painting and meaning, overlapping, line modeling, scattered point perspective, etc. After the stone is polished by plane processing, it traces the pattern text, and then carves lines according to the drawing, with the thickness and depth of the lines, using shadows to reflect the three-dimensional sense. Most of these products are used for exterior wall surface decoration of buildings, with strong artistry.
