About This Product
Features
■Convenience
V-T-i tablets, as the name suggests, are tablets, so they are very convenient to handle and do not stain the product like conventional volatile rust inhibitors.
■Economical
By adding Daipan to Daikan, it provides 10 times more protection than conventional volatile rust preventives (powder) with the same amount.
■Long term
In other words, officially speaking, one V-T-i tablet (approximately 0.5 gs) protects over 1 c.ft and is guaranteed for 5 years.
■Rust prevention mechanism
It is generally believed that the rust prevention mechanism of V-T-i tablets is that the metallic H in HNO2 in the organic nitrite molecule replaces iron. It is said that V-T-i tablets vaporize and then adhere to the iron surface to prevent iron from rusting, but iron originally does not rust unless liquid water acts on its surface, and it does not rust when exposed to air. Unless liquid water is used, the iron surface is covered with a thin layer of invisible ferrous oxide and will not rust or react with the properties of V-T-i tablets.
All volatile rust inhibitors, including these V-T-i tablets, begin to dissolve in liquid water and exhibit their rust prevention function. In other words, it is thought that a substitution reaction with the metal hydrogen in the V-T-i tablet molecules forms a water-insoluble and invisible film on the iron surface, which prevents the iron from turning into rust.
■Steam pressure
Compared to the vapor pressure of conventionally commercially available volatile rust inhibitors of 0.1 mmHg x 10^-3 at 70°F (21°C), V-T-i tablets have a vapor pressure of 4.0 mmHg x at 70°F (21°C). It has been proven that it is by far as high as 10^-3. This means that the initial rust prevention results are very good.
Impact on nonferrous metals, etc.
■Impact on non-ferrous metals
As is generally known, V-T-i locks work perfectly on iron, cast iron, steel, aluminum, tin, nickel, chrome, silver, zinc die-casting, duralumin, anodized aluminum, etc., but on copper, brass, It is said to be somewhat inferior to bronze etc. However, please note that good results cannot be expected with galvanized galvanized materials, lead, cadmium, magnesium, etc.
■Effect on non-metals
Among non-metallic substances, it has no effect on polyethylene, rubber, leather, textile products, paints, etc., but has an adverse effect on chlorine rubber, and discolors vinyl chloride and phthalate resin paints. Therefore, it is necessary to test it in advance.
