Stainless steel screen stainless steel screen mesh we how to detect stainless steel screen 1, different levels of
stainless steel screen mesh antirust function is different, the product is the stand or fall of antirust function according to the testing data to distinguish between different stainless steel screen mesh.
Using the method of the determination of liquid drop a drop in information appearance, not to electricity.
2, stainless steel filter nickel content in about 1% of the 200 series stainless steel screen mesh, the drops of parts will be in 5 seconds into a dark red.
3, nickel content in about 4% of the 202 stainless steel screen mesh, the drop location will not occur red in 10 seconds, the electricity for 5 seconds, when we remove the battery after 30 seconds into a brick red.
4, nickel content in about 6% of the 301 stainless steel screen mesh, droplet parts in red does not occur for 10 seconds, the electricity for 5 seconds, when we remove the battery after 6 minutes into a pale red brick.
5, stainless steel filter most of nickel content in about 8% of the 304 stainless steel screen mesh, drop by the site does not occur red for 10 seconds, the electricity for 5 seconds, when we remove the battery does not change color after 15 minutes.
6, chromium content in about 11% of the 409 and 410 stainless steel screen mesh, when the drop site in 5 seconds into deep brick red.
7, chromium content in about 16% of the 430 stainless steel screen mesh, when the part does not occur red in 10 seconds, the electricity for 5 seconds, when we remove the battery after 1 second immediately into deep brick red.
8, stainless steel filter chromium content in about 21% of the 443 stainless steel screen mesh, when the drop does not occur red parts of 10 seconds, the electricity for 5 seconds, when we remove the battery after 15 minutes.
Therefore, antirust function, the worse of the data, the faster the red, the deeper the color;
As antirust function better at red speed slower, color is more shallow.
As for 200, 300 and 400 series stainless steel screen mesh available magnetic strength to difference.
200 series, 300 series stainless steel screen mesh for non-magnetic or weak magnetic, 400 series stainless steel screen mesh is strong magnetism.
Stainless steel filter note 1, before the test we want to measured data first appearance of dust, dirt, grease, water wipe clean.
2, the determination of liquid drops is best into small round bead around 3 mm, so as to facilitate electricity.
When electricity cathode don't run into steel, make sure there are meet the power battery.
3, this product when there is a slight corrosion, stick on the skin must be washed with water.
4, when we use don't will determine the cap swaps, liquid using the back cover good cap and prevent failure.
5, when measured again test of steel, it should be in a local or wipe clean the original test points.
When now through electric battery cathode wires will wipe clean after use, to prevent trouble.
6, the above test results must be as the approximation, when the same brand of stainless steel screen mesh data due to the arrangement, the condition of appearance affect antirust function elements such as have change the phenomenon may be slightly different.
Other when the environment temperature is higher, also can improve the corrosion of reagent, accelerate the reaction rate, led to the phenomenon is slightly different.
