Weathering steel screen share rusting agent solid rust agent instructions?

Rust potion different methods can make different effects, at the bottom of the peer published the potion instructions, can also be used as a reference. The solution is much the same, (weathering steel screen manufacturers will try to do packaging, logistics, and excellent service) the choice of steel plate material and the cleanliness of the steel plate determine the final effect. In addition, we have not tried the effect of the three-way catalytic converter and other special galvanized materials, but it is reported that they can rust after being burned.

Construction precautions:
1. Tools: plastic watering can, rolling coating,
The effect of rust is affected by climatic conditions
1, climate conditions have a great impact on the effect of rust, to try to avoid in the strong wind, dry, sun exposure conditions to do rust construction.
2, air humidity is the key factor restricting the effect of rust, general air relative humidity is greater than 80% of the condition of rust, will get a better rust effect.
3, in the air relative humidity is less than 60% of the conditions to do rust, easy to lead to insufficient rust, steel plate into blue green, it will take a long time オ will be further transformed into red brown.
(1) If rust must be done under the condition of air dry operation, the rust effect can be ensured by artificially increasing the air humidity:
① Before rust construction, a large amount of wine will be consumed on the ground of the construction site, moisture volatilization, and air humidity will be increased;
② After spraying wine rust reagents, spray wine mist in the surrounding air with a sprayer to increase air humidity.
(2) If the air humidity is not artificially increased in the early stage, when the steel plate is found to be blue-green after rust and cannot be converted into reddish-brown, the surface of the steel plate can be washed with water, dried, and then the air humidity is artificially increased according to the above method, and the rust operation is re-performed.
Second, the reagent can fully react with the steel plate to obtain a better rust effect
If the steel plate is sandblasted and de-oxidized, the reagent will fully contact the steel plate, and the rust effect is fast and uniform, and the effect is the best.
If the steel plate is not sand and other surface cleaning treatment, there will be some attachments (grease, oxide, etc.) on the surface, and the reagent must have sufficient concentration and sufficient amount to dissolve and remove these attachments. The degree of spraying reagent to the surface of the steel plate is not enough; The upper part is sprayed more, the lower part is not sprayed or less sprayed, and it is not possible to think that the reagent will flow from above to below, because the reagent sprayed in the upper part of the process of downward seepage, the concentration of the effective component is getting lower and lower, and the lower part of the steel plate basically does not work. Therefore, the steel plate is placed vertically, the upper middle and lower parts are evenly sprayed with wine reagents, and the test dose should be enough, and it is normal for the reagent to flow along the steel plate to the ground in large quantities after the reaction. In order to obtain the ideal effect of rust, it is necessary to operate according to the amount of reagents and the method of use in the instructions.
It takes a certain amount of time for the steel plate to rust completely, two to three days after rust can achieve a stable rust effect, before achieving a stable effect, it is prohibited to rub the surface of the steel plate.
