Ceramic Fiber Hydrophobic Board

Introduction

The ceramic fiber hydrophobic board is made of ceramic fiber cotton, inorganic filler and a small amount of organic binder and water repellent as raw materials. It is a plate-shaped fiber product that is continuously processed by the fourdrinier printing process. The ceramic fiber hydrophobic board has good water repellency. The hydrophobic rate can reach more than 98%. At the same time, the ceramic fiber hydrophobic board has low thermal conductivity, non-combustibility, moisture resistance, and good sound absorption, and the board includes 6 levels: 1050℃, 1260℃, 1350℃, 1430℃, 1600℃, 1700℃ and 1800℃. Hengrui ceramic fiber hydrophobic board can resist the scouring of airflow for its high strength, so it can be the material of internal linings.

The usability of hydrophobic ceramic fiber hydrophobic board is really good under the condition of high moisture. Hengrui ceramic fiber board has excellent hydrophobicity after processing by specific techniques.
