A rapid determination method for aluminum, calcium and silicon content in solid surface products

Abstract

The invention discloses a quick measurement method for the aluminum, calcium or silicon content of a solid plane material product. The filler component content of the solid plane material is measured by using a handheld X-ray fluorescence spectrum technology, so that the quick detection method for the chemical components of the solid plane material is determined. Compared with the prior art, the method has the advantages that the problem of on-site quick detection of the class and content of fillers of the solid plane material is solved, the filler composition of a test sample is measured by constructing an X-ray fluorescence spectrum working curve formed by the fillers of the solid plane material, and on-site quick measurement of the content of the fillers of the solid plane material is realized.

Description

technical field [0001] The invention belongs to the technical field of solid surface materials, and in particular relates to a rapid determination method for the content of aluminum, calcium and silicon in solid surface material products. Background technique [0002] The filler part of artificial stone mainly has three types: silica, aluminum hydroxide and calcium carbonate. The type and content of filler materials play a very important role in product performance. For example, the solid surface material whose filler is natural stone (mainly composed of calcium carbonate) has far lower mechanical properties such as compression and bending than quartz stone. The shortcomings of natural stone such as radioactivity and poor gloss have gradually attracted people's attention. However, due to the low cost of raw materials for this type of product and relatively high price competitiveness, some unscrupulous manufacturers pretend to deceive consumers one after another. In view of ...

Problems solved by technology

The type and content of filler materials play a very important role in product performance. For example, the solid surface material whose filler is natural stone (mainly composed of calcium carbonate) has far lower mechanical properties such as compression and bending than quartz stone. The shortcomings of natural stone such as radioactivity and poor gloss have gradually attracted people's attention. However, due to the low cost of raw materials and relatively high price competitiveness of such products, some unscrupulous manufacturers pretend to deceive consumers in turn.

In view of the development history and experience and lessons of solid surface materials in the domestic market, the government and relevant industry regulatory authorities expect to promote the healthy development of the solid surface material industry by strengthening the supervision of production, distribution, sales and other links. However, the current determination of the type and content of fillers in solid surface materials The method is very lacking, and the existing relevant detection method uses thermogravimetric analysis to determine the composition and content of solid surface material fillers. This method cannot accurately determine the type and content of fillers, and the detection of filler types is also very limited. At the same time Difficult to achieve rapid on-site detection
