LT-JJ39 1 cubic meter formaldehyde climate chamber
| 1 | Background concentration inside the cabin | TVOC≤0.02mg/m ³, benzene ≤0.5mg/m ³, formaldehyde content ≤0.006mg/m ³, single VOC≤ 0.002mg/m ³ |
| 2 | Cabin environment | Cabin temperature range: 10℃ to 40℃ can be set. The humidity range inside the cabin: 20% to 80% RH can be set. Temperature fluctuation inside the cabin: ±0.5℃ Cabin temperature deviation: ±1.0℃ Humidity deviation inside the cabin: ± 3.0% RH; The time for the cabin temperature to rise from 10℃ to 40℃ is within 30 minutes. Cabin cooling time: Within 60 minutes from 40℃ to the rated extreme low temperature. Temperature and humidity regulation method: BT (H) C balanced temperature (humidity) regulation method; Operating ambient temperature: 5℃ to 35℃ |
| 3 | Airtightness | The pressure inside the test chamber relative to the outside: 10±5Pa. Sealing performance: Static leakage rate: At a relative pressure of 1kPa, the gas leakage volume ≤0.5% of the chamber volume /min. Air change rate: 0.2 to 3 times /h. Automatic servo control, stepless adjustment |
| 4 | Cabin dimensions | Net capacity inside the cabin: 1m ³ |
| 5 | Air purification system | Adjustable external air volume: 0-3 m ³ /h; Intake air temperature and humidity: 10℃ to 30℃, 40-80%rh; Purification method: Fresh air is first subjected to high-temperature degradation, then adsorbed and filtered through an oxide film, and then subjected to temperature control. Humidity adjustment: All the treated air enters the cabin for exchange to ensure the accuracy of the test. |
| 6 | Cabin material | Inner wall of the cabin Welded with ≥1mm mirror-finish stainless steel plates, the inner box body is reinforced with stainless steel profiles on the inner and outer sides of the inner wall. The welding area and its surrounding area are polished to prevent deformation. The edges and corners are all rounded or bevel. It can be cleaned with water. There are no rubber or adhesive materials that may interfere with the test. The sealing materials and other devices that come into contact with the air inside the test chamber do not adsorb organic matter or formaldehyde. Condensation or water droplets must not form inside the test chamber. |
| 7 | Cabin air flow velocity control system | Ensures that the air flow velocity on each surface of the samples inside the cabin is 0.1 to 0.3m/s, which is adjustable |
| 8 | Gas collection device | Formaldehyde absorption sampler: 1 set, in compliance with Appendix A of GB50325-2001 |
| 9 | Controller operation interface | Color LCD touch screen |
| 10 | Attachments | One atmospheric sampler, two sampling bottles. |
| 1 | GB 18587-2001 “Limit of Formaldehyde Emission from Carpets, Carpet Underlays and Carpet Adhesives for Interior Decoration and Renovation Materials” |
| 2 | GB18580-2001 “Limit of Formaldehyde Emission from Wood-based Panels and Their Products for Interior Decoration and Renovation Materials” |
| 3 | GB18584 “Limit of Hazardous Substances in Wooden Furniture for Interior Decoration and Renovation Materials” |
| 4 | LY/T1980-2011 “Volatile Organic Compounds (VOC) and Formaldehyde Emission Detection Box” |
