Objects are coated in a layer of chrome through a process known as hard chrome plating. Chrome plating helps minimize the wear and tear of industrial or engineering parts and can increase their life span.
The hard chrome plating process is an electroplating process in which chromium is deposited from a chromic acid solution. Chroming tanks house these chemical reactions, which can be hazardous to humans and can lead to environmental concerns if not properly contained.
Unfortunately, the harsh chemical reactions in hard chrome plating tanks can easily dissolve tank liners and render them ineffective. As a result, it can be crucial for you to find tank liners that can withstand the chrome plating process and protect the surrounding area from harmful leakages.
3 types of trusted liners for chroming tanks
Because the chrome plating process is highly oxidizing, it can degrade certain liner materials over time. Therefore, chroming tank owners need to know which tank liners are safe to use for the hard plate chroming process. The following tank liners are trusted for use in chroming tanks:
- PTFE Teflon — Teflon is a versatile plastic that is often used as a coating and can function up to 260 degrees Fahrenheit. It is also highly resistant to strong chemicals and does not react with oxygen exposure. LFP CrossFilm is a type of patented Teflon material that is manufactured to be much stronger than regular Teflon. Overall, however, Teflon liners can effectively protect tanks during the chrome plating process, lasting for a long period of time and requiring minimal maintenance costs.
- Kynar (PVDF) — Tanks made from PVDF material can withstand temperatures of up to 300 degrees Fahrenheit. Its high chemical resistance and durability make it ideal for industrial processes like chrome plating.
- Koroseal PVC liner — You can line your chrome plating steel tank with a Koroseal PVC liner, one of the most cost-effective liners on the market. This type of liner has a unique formulation that resists corrosives and can function at 200 degrees Fahrenheit. It is therefore often used for chrome plating tanks. For extra protection, you can use an LFP CrossFilm (made out of PTFE Teflon — see above) material as a skirt around your PVC liner. Skirt liners are especially used in chrome plating tanks because the chemical reactions can be especially corrosive at the upper and lower levels of the tank.
