13530-50-2 Dihydrogen Phosphate High Temperature Binder

The most comprehensive application of dihydrogen phosphate high temperature binder

1. Property:

As a high-temperature adhesive, aluminum dihydrogen phosphate has the characteristics of strong chemical bonding, hardening at room temperature, high temperature resistance and erosion resistance under high temperature conditions. As early as the 1980s, the foundry industry began to use aluminum dihydrogen phosphate as a binder for the shell-making process. In recent years, some experts have conducted research in this area.
Industrial products are divided into liquid and solid states.
The liquid is a colorless, odorless, viscous syrup, and the solid is a white powdery crystal.
Material grade aluminum dihydrogen phosphate has good room temperature adhesion, high temperature cementation, high temperature resistance, shock resistance, corrosion resistance, and airflow resistance. It is an ideal chemical bond.

2. Usage:
Solid aluminum dihydrogen phosphate: mixed with refractory aggregates, hardeners, etc. at room temperature to form high bonding strength at a constant temperature of 90-110°C for 4-24 hours. After drying at 350-500°C, it has high resistance Flexibility, compression resistance, and hydration resistance, even if it is soaked in water or boiled, it will not become soft Used in refractory spray coatings, fire mud, castables, ramming materials, and phosphate bricks.
Liquid aluminum dihydrogen phosphate: AP135; P2O5%>=33; AL2O3%>=8; specific gravity 1.30-1.50; use refractory spray paint, fire mud, castable and bonding agent for foundry industry, mainly used for corundum in refractory industry , Chromium corundum nozzle, production of chromium aluminum zirconium corundum brick for coal water slurry gasifier. Easy to mix and shape, especially suitable for on-site construction.
