application

Acid rain, bird droppings, fuel, antifreeze, and many other environmental factors can damage the paint on car surfaces Especially in summer

Some substances are destructive and cause serious damage, so car paint manufacturers and car manufacturers need to find out what kind of impact different environments have on coatings

It is very important to evaluate the temperature range and temperature for the construction of baking paint systems and quality inspection of ovens,

Correspondingly, the composition of the paint formula (the inherent characteristics and quality of the entire product) will change Typical examples are the yellowing of adhesives and the discoloration of pigments.

For baking paint in industrial production, control the corresponding baking process, meet the quality requirements and ensure its stability

crucial. Due to various reasons, the actual situation may not necessarily be consistent with the preset conditions, and in bad cases, it may result in a serious scrap rate.

The gradient oven 432 provides a possibility for optimizing the process based on the needs of problematic products

The actual temperature condition of the oven in the production line can be measured in advance by a furnace thermometer, which can simulate the corresponding temperature gradient as needed, achieving a nearly 1:1 perfect simulation of the oven situation, saving time and cost for laboratory level equipment.

working principle

Gradient oven 432 is a device used to evaluate the baking and drying characteristics of products, and its detection objects include paint and

Powder coatings, resins, plastics, and similar products

By programming the heating speed, baking temperature, and time, the actual production process can be simulated

The gradient oven helps accelerate product development, save time and costs. The oven has * repeatability, which can very accurately determine the current limit value.

The coating test temperature is 320 ° C. Using a dual coating machine, two coatings can be applied simultaneously on one sample

Different coatings This makes it easier to save time and material costs The gradient oven testing process in paint quality control is much faster than traditional convection ovens.

In standard testing, five different chemicals can be tested on one sample, such as sulfuric acid for simulating air and acid rain, sodium hydroxide for car cleaning agents, * (bird droppings), brake fluid, and resin.

Liquid paint can be coated using a coating machine and coating device After covering the edges and back of the sample, it can also be coated by spraying

Powder coating can cover the sample or cover it with a magnetic strip, and then apply the coating through electrostatic spraying After coating the sample, bake it according to the specified process conditions

Place approximately 0.05 milliliters of this type of reagent onto the sample at regular intervals using a pipette, with a spacing of 2-3 centimeters between the reagents

Then program the gradient oven to set the linear gradient range to 35 ° C to 80 ° C

When evaluating the sample, first bake it at high temperature, then rinse it with running water, dry it, and visually evaluate it The evaluation should be conducted 1 hour later and observed again 24 hours later for the presence of other corrosion points.

Record the temperature when the appearance begins to change and break

The gradient oven 432 is equipped with a microprocessor controlled heating platform and 45 insulated heating elements, which can generate linear temperature gradients or gradients Linear gradient "means that the temperature remains constant throughout the entire testing process. Linear gradient can be horizontal, such as the same temperature on the left and right sides of the sample. Of course, the temperature can also be low on the left and high on the right, with a large temperature difference of 100 ° C

Ladder Degree ": Three steps can be provided to automatically divide the sample into 2, 3, and 4 identical parts (temperature gradient) Some heating elements are not heated between temperature gradients to maintain the set temperature for each gradient These heating elements will be recorded or set to display a temperature of 23 ° C in the report.

Gradient Oven 432 is a laboratory bench top instrument that can be placed in non hazardous locations with normal ambient temperature (approximately 18 ° C to 25 ° C) and humidity (<85%)

The instrument is operated and controlled through a menu, with operating languages including English, French, and German, and a built-in alphanumeric keyboard. All functions can be displayed on the screen with corresponding menus.

The gradient oven has three interfaces Two of them are used to start the printer and transfer data to the computer the third interface

Used for connecting furnace thermometers/data loggers for data exchange The software for data exchange has been installed The configuration includes a special glass panel for isolating heating elements and testing samples, as well as special testing samples.

There is a louver installed in front of the oven, and for safety reasons, the louver must be closed before and after heating during the transfer of the sample holder.

The gradient oven meets the Level 1 safety standard All ovens undergo strict quality testing in accordance with DIN VDE 0700
