What Is The Working Principle Of The Pastillator Cleaning?

Shanghai Rebo Granulator Co.,Ltd | Updated: Aug 14, 2017

What is the working principle of the Pastillator cleaning?
When the negative or positive electrode strip passes through the spindle slot, the strip becomes the positive or negative pole of the Pastillator. In the process of the ingot, there is a small amount of hydrogen or oxygen on the surface of the strip, which has the effect of promoting the stripping of the dirt from the surface of the cleaned strip. In the use of the ingot degreasing is the use of sodium hydroxide, sodium carbonate and other alkaline aqueous solution, the presence of these strong alkali inorganic ions, increasing the conductivity of water, but also to promote the removal of dirt. Because the lye on the lipid oily dirt has a strong dispersion of the role. However, the addition of alkaline substances such as sodium hydroxide to the mineral oil and other dirt dispersion is weak, so in the solution by adding sodium metasilicate and a small amount of surfactants to facilitate the dispersion of mineral oil dirt removal.
When the color coated substrate is zinc or aluminum, due to poor alkali resistance, the use of sodium silicate and other weak base as the ingot, sodium metasilicate on the non-ferrous metal corrosion resistance has a significant improvement. When the aluminum anode polishing Pastillator when the wax (that is, the defatted metal aluminum and the spindle Pastillator battery power positive connection, in the process of metal ingot as the anode in the anode gold surface aluminum surface precipitation of anhydrous silica gel film, protection Aluminum is not shouted when the added surfactant has excessive foaming properties that are detrimental to degreasing, using low foaming surfactants or daytime to support the amount of surfactant.
The method of degreasing the Pastillator is classified into a cathode degreasing and anodic degreasing according to the case where the degreased substrate is used as an electrode. The degreased substrate and the negative power supply connected to the cathode called degreasing. As the process of the ingot, the hydrogen generated in the cathode is twice the oxygen produced by the anode, so the hydrogen produced by the cathode on the substrate surface dirt stripping effect is better. However, if the treatment is excessive, in the cleaning object that is the surface of the strip will form a powder material, at this time to be post-acid treatment to remove these substances. Another time when the steel electrode cathodic degeneration will produce hydrogen and will be absorbed to cause brittle nature, this phenomenon known as hydrogen embrittlement. The occurrence of hydrogen embrittlement with a variety of high, low carbon steel and metal zinc most obvious. And the brittleness is proportional to the amount of hydrogen absorbed. Therefore, the steel substrate is usually not the use of cathode screw Pastillator degreasing and more use of anode degreasing.
