As far as I know, many chlor-alkali companies use FRP chambers for chlorate decomposition, but these chambers leak due to their inability to withstand high temperatures. So, what material do experts recommend for chlorate decomposition chambers? ， ， -
Ours doesn’t leak; it’s made of FRP. What are your temperature and pressure settings?
When using FRP, as long as the operations are carried out as required, there are generally no problems； Using titanium might not be good, as it is not resistant to hydrochloric acid
Titanium can be used, as well as fiberglass!
We use titanium material, and as long as it is handled properly, it should not be corroded by hydrochloric acid
Some manufacturers use titanium for the material of chlorate decomposition tanks, while others use FRP; each has its advantages and disadvantages. Titanium is not resistant to acids, and acid is required in the chlorate decomposition process, so it can be corroded if not used properly. There are many types of FRP available on the market, and due to the significant variations in the quality of fiberglass materials in China, even products of the same model can differ in quality. Therefore, special attention must be paid when making purchases. There is a type of FRP called D470, which performs relatively well. The fiberglass material used for chlorate decomposition tanks must meet strict requirements.
It is recommended to use titanium, as chlorates have a high corrosive strength. Using titanium material prevents corrosion. The problem of hydrochloric acid corrosion can be solved by fitting a PTFE lining over the pipe through which the acid is introduced.
Some manufacturers use titanium, while others use FRP for the materials in chlorate decomposition tanks; personally, I think titanium is the better choice, although it is more expensive.
Reply to 1# Qilian Mountain: Both fiberglass and titanium materials are acceptable. When using fiberglass reinforced plastic, attention should be paid to the type of resin selected
Chlorates have a high corrosive strength; it is recommended to use titanium materials. Although the cost is higher, it is still a worthwhile choice in the long run. At room temperature, as long as the hydrochloric acid concentration does not exceed 10%, titanium can be used effectively. The key is to strictly control the process of adding acid!
