Product Introduction
Product Details
Production method:
Zircon ramming material: with high density, high temperature resistance, resistance to glass liquid erosion, glass liquid extremely low pollution of unshaped refractory material, it mainly with zircon sand as aggregate, the main content of zirconia and silica. The use of different positions, different zirconium content ratio, the general zirconium content is divided into Zr≥ 50%,Zr≥ 60%,Zr≥ 63%,Zr≥ 65%. Mainly used for: the protective layer of the upper pool wall of the glass furnace, the flow hole, the working pool and the material channel. It is also usually used in cold repair and hot repair of pool furnaces.
Method of use:
1. Adhesive preparation
The adhesive is aluminum dihydrogen phosphate, already prepared and packed in plastic bags. The rammed mixture shall be packed in polythene bags of 25kg each.
2. Mixing and stirring
A) Put aluminum dihydrogen phosphate in enough water for attenuation (metal containers should be avoided), then mix it with the tamped mixture, and mix it with a machine or manually.
B) Place the mixture for about 10 hours or longer for mixing and aging.
C) Judge whether the mixture is suitable for use. If it is too dry, add water and stir until it is suitable for use.
3. Construction
A) The construction site should be cleaned to avoid any impurities, and air hammer or manual compaction can be used.
B) The ramming movement shall be carried out in one direction without rest. Each ramming surface should cover another 1/3 of the area, and each layer of material should also cover another layer to avoid ignoring the space.
C) The thickness of the base mixture is 40-60mm, which shall be compacted to 1/2 of the thickness of the base after compaction. The surface of the compacted mixture shall be kept rough for the next compaction process to be continued until the required thickness of the mixture is achieved.
D) After the compaction process starts, it should be stopped immediately. If stopping cannot be avoided, the surface of the mixture should be kept rough and covered with plastic film to avoid delamination and induration.
E) When the entire process is completed
