The gradient oven supplied by Wewon Environmental Chambers Co., Ltd. permits scientists and quality examiners to perform synchronous testing of coatings, crude materials and synthetic compounds at various temperatures in a similar advance. It understands that the testing steps reproduced in the lab can be replicated to the real creation measure (box type or chain type open hearth). What’s more, the adaptability of the temperature setting of the gradient crystal oven can program a temperature that recreates an ideal explanatory inclination change, giving ascent, fall or other temperature reenactment conditions.

Acid rain, bird droppings, fuel, antifreeze and many other environmental factors can damage a car’s finish. Especially in summer, certain substances can be very corrosive and cause serious damage. Therefore, both automotive paint manufacturers and automobile manufacturers need to find out how different environmental phenomena will interact with the paint system. Concerning the subject of prepared coatings inside mechanical creation conditions, the precise control of the comparing measures is of essential significance to accomplish and ceaselessly keep up/ensure the predetermined subjective attributes of the covering. Because of various reasons, the really existing conditions don’t generally compare precisely to the preset cycle run which in the “thinking pessimistically” may cause seriously high non-similarity costs.
Compared With the laboratory oven, The gradient-oven offers the chance of a necessities based enhancing of the cycle for the item being referred to. The “actual condition” in the oven plating creation line, previously controlled by methods for a broiler temperature recorder, can be reenacted at the best by means of a necessity orientated setting of a proper slope and subsequently permits an almost ideal 1:1 recreation of the particular stoving condition, anyway on the ideal research facility scale saving time and costs.
For a variety of reasons, the actual conditions that exist don’t always correspond exactly to the preset process, In a “worst case” scenario, this could result in significant nonconforming costs. Gradient ovens offer the possibility of requirement-based process optimization for the product in question. The “actual conditions” in the furnace enamel production line determined in advance by the oven temperature recorder can be best simulated by appropriate demand-oriented gradient settings. Thus, a perfect 1:1 simulation can be achieved. However, on the desired laboratory scale, the respective baking conditions save time and expense.

Compared With The Laboratory Oven, What Are The Advantages of Gradient Oven ?
● Test Device’s Test Area Is Fully Heated: The test floor is fixed on the glass bed outside the transparent cover and automatically smoothed to the appropriate position. Once the test baseplate reaches the heating zone, a special magnetic yoke exerts downward force on the baseplate, resulting in more thermal contact between the baseplate and the heating zone.
● Gradient Oven With Accurate Test Data: The control of the infrared heater is very precise, but the temperature transmitted to the test board itself is an uncertain factor. This problem is solved by an integrated temperature sensor that detects and controls each in-yoke heater. The current reference temperature is taken from the test board itself, which ensures that the test results are true and reliable, regardless of the shape or material of the test board itself.

● Test Equipment’s Diversified Functions: The gradient oven produced by Wewon Tech has an ultra-wide temperature range. It can vary from room temperature to approximately +350°C and can be set for up to 30 independent zones. Its ultra-wide temperature range combined with flexible programming and ultra-fast heating makes it suitable for a wide variety of tests.
Depending on the type of gradient oven, the coating can be tested at temperatures up to +300°C. By using the duplex frame coater coating system, Two different coating systems can be applied simultaneously on the same panel. This makes it easier and saves application time and material costs. In quality control tests of baking coating systems, gradient ovens produced repeatable results many times faster than conventional convection laboratory oven. In standard tests, five different chemicals can be tested on a single panel, such as H2SO4, which mimics the atmosphere and acid rain, NaOH for car washing detergents, trypsin, brake fluids and tree resins.
The liquid coating is applied through a film applicator and film applicator. Once the sides and sides of the test panel are covered, they can also be applied by spraying. The powder coating is applied to a mask plate or a magnetic strip-covered panel by means of static electricity. The panels are coated and baked under specified processing conditions. Droplets of these various materials (approx. 0.05 mL) are placed on the test plate at appropriate intervals using pipettes. Repeat this length down the panel with an interval of about 2-3 cm.
