Scope

Scope: This document specifies the terminology definitions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, shelf life requirements, and sales and service requirements for zeolite deodorizing stones. This document is applicable to products prepared from natural clinoptilolite raw materials and having deodorizing functions; Main technical content: Physicochemical indicators shall meet the requirements of Table 1. Table 1 Item Indicator Superior Grade First Grade Ammonia adsorption value a/(mmol/100g) ≥110.0 ≥100.0 Blue adsorption/ (g/100g) ≥45.0 ≥35.0 Volatile organic gases (TVOC) adsorption rate/ (%) ≥88 ≥80 Ammonia adsorption rate/ (%) ≥95 ≥90 Moisture and volatile substances/ (%) ≤12.0 ≤14.0 Solubility/ (%) ≥100.0 ≥95.0 Water absorption/ (%) ≤60.0 ≤55.0 Silica (SiO2)/ (mg/100g) ≥30.0 Alumina (Al2O3)/ (mg/100g) ≥14.0 pH (25℃) 4.5–10.5 a The content of zeolite is linearly related to the ammonia adsorption value. According to industry practice, the zeolite content in the product is determined by measuring the ammonia adsorption value.
