Scope

Scope: This document specifies the term definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and sales and service requirements for zeolite air purification particles. This document is applicable to zeolite air purification particles prepared from natural clinoptilolite as raw material, which are used to purify formaldehyde, benzene, ammonia, nitrogen, sulfur dioxide, volatile organic gases (TVOC) in the air, as well as heavy metal ions such as lead and mercury in the air. They can be used as additives in tobacco and filter tip materials, effectively reducing the nitrosamine content in smoke. Main technical content: Physical and chemical requirements shall comply with the requirements in Table 1. Table 1 Item Indicator Superior Grade First Grade Ammonia Adsorption Value/ (mg/100g) ≥ 150 ≥ 120 ≥ 100 Specific Surface Area/ (m2/g) ≥ 1000 ≥ 800 ≥ 600 Particle Size a/ (μm) ≥ 0.2 - 0.5 ≥ 0.8 - 0.5 ≥ 2.0 - 5.0 Particle Size b Passing 0.5mm - 1.0mm sieve/ (%) ≥ 98 Passing 1.5mm - 2.0mm sieve/ (%) ≥ 98 Passing 2.0mm - 3.0mm sieve/ (%) ≥ 98 a The particle size of the powder material obtained after purification and modification of natural clinoptilolite ore can be used directly in special application scenarios. b The granular material processed from the powder material is suitable for different application scenarios.
