3. Test results from professional institutions

4. Analysis of the Five Major Reasons for the Explosion of Poker Cards

1.chemical residue: Low-quality inks and bleaches may produce flammable gases that can accumulate in confined spaces.

2.Special workmanship defects: Some magic pokers have built-in electronic components or chemical coatings that pose safety risks.

3.extreme environmental factors: High temperature (>60℃) or high humidity (RH>85%) environment may cause material degeneration.

4.static electricity buildup: Rapid shuffling in a dry environment may generate electrostatic voltage exceeding 15kV.

5.mechanical stress concentration: Special folding methods may cause local stress to exceed the tensile strength of the paper (usually 40-60N).

5. Consumer Safety Guide

6. Opinions of Industry Experts

Li Ming, deputy director of the China Cultural and Educational Supplies Quality Supervision and Inspection Center, said: "Recent random inspections found that about 18% of commercially available playing cards do not meet national safety standards. It is recommended that consumers look for the GB/T 3038-2021 mark when purchasing and avoid products with pungent odors."

Professor Wang from the School of Materials at Beijing University of Chemical Technology pointed out: "In order to reduce costs, some Sanwu products use recycled pulp and industrial dyes. These materials may indeed undergo exothermic reactions under certain conditions. It is recommended that playing cards be stored in a cool place below 25°C."

7. Forecast of future trends

As the incident continues to unfold, the e-commerce platform has removed 37 problematic products from the shelves. The National Standardization Administration Committee plans to revise the playing card production standards and add 6 new safety testing indicators. It is expected that the price of compliant playing cards may increase by 10-15% in the next three months, but security will be significantly improved.
