Product Details

Number: GBW (E) 010549

NameZBK404 blast furnace slag

Specification: 100g

This standard substance is applicable for product quality inspection of slag materials, calibration of measuring instruments, evaluation of measurement methods, and assignment of values to materials.

Preparation method:

Raw material selection for slag composition design: Dry E-type crusher, coarse crushing, roller crusher, fine crushing, ball mill, grinding and screening<80 µ m (180 mesh), mechanical mixing, sealing, preservation uniformity, initial inspection, vacuum packaging uniformity, re inspection, mathematical statistics, constant value

Uniformity inspection and stability assessment:

Randomly select 20 bottles from the packaged samples, and use the variance (F) test method to obtain the data. The test result shows that F<F α (0.05), indicating good sample uniformity. Testing method: sulfur infrared absorption method; Silicon dioxide, total calcium, calcium oxide, ferrous oxide titration method; Iron, aluminum oxide titration method, and inductively coupled plasma atomic emission spectroscopy; Magnesium oxide, titanium dioxide, manganese oxide, phosphorus pentoxide, sodium oxide, potassium oxide inductively coupled plasma atomic emission spectroscopy; Fluorine ion selective electrode potential method. Minimum sample size: 0.05g sulfur, 0 for other components 1g。

Traceability:

Multiple laboratories collaborate to set values, with most of the units being qualified nationally recognized units or units with years of experience in developing or measuring standard substances. The instruments used in each laboratory have passed metrological verification, and the reference materials or standard solutions used are all reference materials with confirmed purity or certified standard solutions approved and published by the state. Using accurate and reliable testing methods based on different principles, such as S being determined by gravimetric, infrared absorption, and titration methods, SiO2 being determined by gravimetric and titration methods, Al2O3 being determined by titration and ICP-AES methods,

Packaging, use, and storage:

Bottled, net weight 100gAluminum film sealing. Before use, it should be placed in an oven 105Dry at ℃ 2hTake it out and place it in a drying oven to cool it to room temperature Later use. Immediately tighten the bottle cap after use and store it in a dryer to prevent moisture absorption and oxidation.
