What are the effects of alumina on the properties of ceramic fiber paper? Recently, many customers contacted us and asked us about the problems they encountered during the use of ceramic fiber paper. I hope we can help. Today, I will share with you the knowledge about ceramic fiber paper. Let’s discuss it together, hoping to bring inspiration and help to our customers and friends, and let everyone have a deep understanding of ceramic fiber paper. Alumina used in ceramic fiber paper is divided into liquid alumina and colloidal alumina. Alumina in different states has different effects on the properties of ceramic fiber paper, but what will be the impact of specific alumina on the properties of ceramic fiber paper. Let me explain it through the experimental data.
The tensile index of ceramic fiber paper increases from time to time. When the amount of colloidal alumina is 20%, the tensile index of ceramic fiber paper is 0.82n? M / g. with the increase of the amount of colloidal alumina. When the dosage of colloidal alumina increased to 25%, the tensile index was 0.91n? M / g, which increased by 11.0%. When the dosage of colloidal alumina increased from 25% to 40%, the tensile index changed from 0.95n? M / g to 1.92n? M / g, and the increased percentage was 13.7%, 55.6% and 14.3% respectively. It can be seen that with the increase of the amount of colloidal alumina, the tensile index of ceramic fiber paper increases at a low rate at first, then increases rapidly, and finally decreases gradually.
With the increase of the amount of colloidal alumina, the loss on ignition of ceramic fiber paper is also increasing. The dosage ranges from 20% ~ 40%, which can be seen at the same time. The loss on ignition increased by 23.1%, 29.1%, 7.3% and 6.7% respectively. The curve rose rapidly at the beginning, and the rising range gradually decreased with the continuous increase of the amount of colloidal alumina.
From the above analysis results, it can be obtained that the tensile index of ceramic fiber paper increases with the increase of the amount of colloidal alumina. The rate of increase is small first, then large, and finally gradually reduced. The change of loss on ignition also increases from time to time with the increase of dosage, but the increase range will gradually decrease.
