Wear-resistant ceramic coatings use phosphate solution as a binder, with corundum aggregate, corundum powder, α-Al2O3, SiC micropowder, ultrafine powder and a variety of additives. After the construction is completed, it can be directly ignited and produced. A new type of wear-resistant and refractory coating material. It has the advantages of strong adhesion, wear resistance, chemical corrosion resistance, peeling resistance, short curing time, and can be combined with various refractory materials.
1. Packaging
Wear-resistant ceramic coatings are packaged in 25kg/bags, with a small plastic bag of coagulant (to adjust the initial setting time of plastic), and barreled phosphate solution as a binder, with an addition amount of about 12% of the bagged powder.
2. Storage
Wear-resistant ceramic coatings must be stored in a dry warehouse, not exposed to rain or moisture, and the shelf life is 12 months.
3. Construction instructions
1. Mixing preparation: Use a forced mixer to mix, all mixing tools must be clean, and must not be mixed with mud, lime, silicate cement and other debris.
2. Add the coagulant. According to the construction environment temperature, choose the appropriate amount of coagulant. When the temperature is less than 20℃, the coagulant can be added completely; when it is greater than 20℃, the amount of coagulant can be adjusted appropriately according to the construction time requirements.
3. Stirring: It is advisable to add 4-6 bags of 100-150 kg of wear-resistant ceramic coating each time, then add the coagulant and dry mix for 2 minutes, and then add about 12-18 kg of phosphate solution, stir into a "dough shape", and put the material in when it is plastic.
4. Construction: Clean the construction site, and the inner wall must not be sticky with debris and dust. First, clean the floating objects on the tortoise shell net or the nails, clean the dust and debris on the construction work surface, and then apply the wear-resistant ceramic coating by hand. The construction site can be flattened and smoothed with tools such as iron plates, and the interface must be tight. For construction areas with a large area or a thickness greater than 50mm, anchors should be welded, and the spacing should not exceed 50mm.
5. After the wear-resistant ceramic coating is initially solidified, the construction site can be moved after 24 hours of natural curing, and it can also be ignited for production.
6. The wear-resistant ceramic coating can be closely combined with various castables and refractory bricks.
7. This material must not be mixed with any other castables. The initially solidified wear-resistant coating cannot be stirred with glue and should be discarded.
8. After the wear-resistant ceramic coating is initially solidified, it does not need to be cured or baked, and can be directly ignited and heated for use, and its performance will not be affected.
