In order to purchase genuine ceramic fiber paper to avoid economic losses, today I will share with you how to identify high-quality ceramic fiber paper:
1. The weight of a single piece of ceramic fiber paper of conventional product size is about 7 kg, while the weight of counterfeit products is relatively light or heavier.
2. High-quality ceramic fiber paper is more expensive because of its higher cost. And the relatively low price is undoubtedly the inferior product.
3. The original product is relatively pure in color and will not appear variegated, and the color is white, but not particularly white. The color of the imitation product will appear variegated and chaotic, and it is generally yellowish.
4. Look at the content of slag balls. This does not need to be tested by equipment. You can sense how much with your hands. Firstly, touch the surface to see if there is too much powder in the slag balls. Then touch after tearing, how big the slag balls are in the crack, and whether they are pierced or not, etc. The reason for this is that many manufacturers simply apply a layer of glue on the surface in order to look good on the surface or to cover up the fact that there are too many slag balls. In fact, this kind of ceramic fiber paper is the most unusable, because this layer of glue will volatilize when exposed to high temperatures. Only the ceramic fiber is left, then there will be delamination or scattering.
5. The method of burning test is very simple, just use your lighter or gas stove to ignite it directly to see if there is any peculiar smell and smoke during the test, and if it will return to white after a period of burning. After the test, see if the ceramic fiber paper will delaminate or fall apart. Good fiber paper has almost no peculiar smell and smoke, and will not delaminate or disperse after being exposed to high temperatures.
6. The most important point is to try it in your own equipment or objects. After the trial, we will naturally know which is of good quality and which is of poor quality. Of course, you can't just look at the surface, you need to comprehensively consider which is good and which is bad from many aspects.
