At present,with the widespread use of fired bricks,there are more and more fired brick manufacturers in the market,but the quality is also uneven.If we encounter this situation when selecting fired bricks and do not know the quality,we should not blindly choose,but conduct certain quality inspections.So how to conduct purity identification on fired bricks?
1.Fired bricks contain kaolinite,which can be identified from the perspective of kaolinite content.High quality fired bricks contain more kaolinite,while those with poor quality contain less.
2.Identify the content of alumina and silica,and calculate the ratio of the two.The larger the ratio,the higher the refractoriness.Conversely,the smaller the ratio,the lower the refractoriness of fired bricks,and the wider the sintering melting range,the higher the purity of fired bricks.
3.Identify the impurity content in the product,the lower the content,the higher the refractoriness,and the higher the impurity content,the lower the refractoriness.
Our testing of the purity of fired bricks is not only for the purpose of purchasing high-quality materials,but also for the smooth construction and convenient maintenance in the later stage.There are strict requirements in the use of fired bricks.In order to reduce the impact on later construction,the performance,hardness,purity,and other aspects of the brick material should be considered when purchasing fired bricks.Brick materials are the key to the entire building,and once quality issues arise with critical materials,they can have a series of impacts on the stability,safety,and other aspects of the building.So when making a purchase,it is important to seek reputable manufacturers and the buyer should also have knowledge of all aspects of fired bricks.
