Name the application first when comparing this treated calcium carbonate. The material is industrial surface-coated activated CaCO3, described as white superfine powder with stated purity ≥98.5% and a 1500 Mesh model designation.
Give the formulation or process a clear acceptance brief
Paint, plastic, rubber, paper making and building are the named assessment areas. Describe the particular system and the properties that will decide whether the proposed sample is acceptable. A conclusion for one formulation does not establish suitability across the other uses.
Match treatment and particle evidence to the sample
Request the coating chemistry and treatment information for the grade being proposed. Ask how those properties were established rather than inferring an agent, treatment level or compatibility from activated or surface-coated wording.
- Obtain the particle-distribution or sieve report behind the 1500 Mesh designation.
- Confirm the purity threshold with current composition and impurity analysis.
- Request numerical whiteness or other physical tests where the brief requires them.
Use representative results to complete the comparison
The mesh designation is not a measured micron distribution, and white appearance is not a numerical optical result. Agree the conditions used to evaluate the actual sample and retain observations against the acceptance criteria. No dispersion improvement, reinforcement, coating performance or universal addition ratio follows from the treatment name alone. Keep the material reference with current technical, analysis and safety reports so the qualification remains linked to the powder and system assessed.
