Introduction
In-depth interpretation of national standards for natural stone protective agents
| Standard dimensions | Technical requirements | Scope of application | Testing methods |
|---|---|---|---|
| Term definitions | Clarify key concepts such as protective agents, white bloom, water spots, and rust spots. | Applicable to all natural stone products. | Verify term consistency through tests. |
| Classification and naming | Classified by dispersion medium (water-based, solvent-based), function (waterproof, oil-proof) and use site (facing, bottom). | Guide product development and application. | Unify the naming method through labeling standards. |
| Technical requirements | Surface protective agents must meet indicators such as color stability, pH range, water resistance and stain resistance; bottom protective agents must meet impermeability and cement bonding strength. | Applicable to stone decoration and construction applications. | Verify technical parameters through test methods. |
Explanation of professional terms and actual cases
White Mark refers to the white powder formed when the soluble substances inside the stone reach the surface through capillary action and dry. In building exterior walls or decoration projects, the white mark phenomenon often causes damage to the appearance of the stone.
Water Mark is a mark left by water that has penetrated into the stone and has not completely evaporated. It is common in humid environments or improperly protected stone surfaces.
Background of Standard Formulation and Analysis of Technical Evolution
GB/T32837-2016 standard is formulated based on the actual needs of the stone industry, aiming to improve the durability and decorative performance of natural stone. With the improvement of the construction industry's requirements for stone protection, this standard has added a number of technical indicators on the original basis and refined the test methods.
Implementation Suggestions
- Manufacturers should strictly follow the standards for raw material screening and quality control.
- Construction parties need to select the appropriate type of protective agent according to the type of stone and follow the correct coating process.
- Users should conduct sample tests before use to ensure that the protective effect meets expectations.
