Iron oxide red is a red-brown industrial pigment that is often used by people to make dyes, paints, etc. With the market competition, there are many fake iron oxide red on the market. Because real pigments and fake ones are nothing from the outside. The difference is that the use effect is directly different. In order not to affect the use effect of the product, we still need to know a few distinguishing methods:
1. Generally speaking, the covering power of iron oxide red is relatively strong. If you paint the wall with real iron red, you can make the wall smoother and more exquisite, the red on the surface is more uniform, and there will be no glare. Produced, but this does not happen for fake ones.
2. The shape and particle size, surface area, and relative density of iron oxide red particles are determined by the preparation method. When producing iron oxide red, there are two preparation methods: wet method and dry method. Everyone still chooses iron oxide red. Can be distinguished based on these.
3. The oil absorption of iron oxide red is a very important indicator. Like other pigment applications, the wetting of iron oxide in the application system is an important part of the entire dispersion process. The quality of the wetting effect depends on the degree of affinity of the dispersion medium and the surface morphology of the pigment, as well as the molecular form of the dispersion medium and the pigment Spatial interaction of agglomerate structures.
The above are the tips to identify iron oxide red. I hope it can help everyone to choose iron oxide red products more smoothly.
