Product Description Product DescriptionIntroduction of Test chamberAt present, the main component of plastic runners in China is toluene diisocyanate (TDI), whichis composedofpolyether, polyurethane material, rubber particles, EPDM (ethylene propylene diene monomer) particlesorPU(polyurethane) particles, pigments, additives and so on. Its toxicity mainly comes from the use of toxic toluenediisocyanate,plasticizer, chlorinated paraffin and so on. TDI polyurethane runway, which is widely laid, contains a varietyof toxicandharmful chemicals in its raw materials, which will release toxic gases when exposed to temperatures above20degreesCelsius or ultraviolet radiation. The main component of plastic runway is polyurethane. At present, the possible toxic pollutants of inferiorplasticmainly come from three parts: 1. The solvent used in plastic runway volatilizes toxic toluene and xylene, whichhasirritatingodor and can cause skin itching, dizziness and other symptoms. 2. Low-quality plastic runway contains leadsalt, aheavymetal drier, which can promote runway solidification and fixation, but heavy metal lead will cause permanent pollution. Afterlong-term contact between children's skin and the plastic runway, lead penetrates into the body, causingbloodleadtoexceed the standard, that is, lead poisoning. 3. The most harmful is the poisonous plasticizer used in therunway. Itcanincrease the elasticity of the inferior runway and make its elasticity up to the national standard. Phthalate ester plasticizersare the most common plasticizers. Overuse may even lead to sterilization of boys. The test box provides a clean enclosed space to accurately control the temperature, humidity, backgroundconcentration, wind speed, relative pressure and ventilation rate in the cabin. It is used to simulate the pollutant release process of products under specific environment. It is used to test whether the plastic runway materials canmeet the requirements of T/310101002-C003-2016 "Limit of harmful substances on plastic surface of school sports ground".Applicable standardsGB 36246-2018-Playground of Synthetic Material Surface in Primary and Secondary SchoolsT/310101002-C003-2016The Limit of Hazardous Substances on Plastic Surface of School Sports GroundsASTM D 5116-97Standard Guidelines for the Determination of Organic Releases from Indoor Materials andProductsinSmall-Scale EnvironmentsASTM D 6007-02 Standard Test Method for Determining Formaldehyde Concentration in Wood ProductsReleasedGases in Small Environmental BoxASTM D 6330-98Standard operation for determination of VOCs (except formaldehyde) release fromwoodpanelsinsmall environmental chambers under specified test conditionsISO 16000-9 EN 16516 IntroductionMain box body : high strength carbon steel shell, stainless steel cabin, polyurethane insulationlayerTemperature Control SystemIndirect Temperature Control Method in Constant Greenhouse (4 workingcabinsinconstant temperature cabins)Humidity Control System : Proportional Control of Dry Gas and Wet Gas (Independent Control of EachCabin)Background concentration control: High cleanliness working cabin, high cleanliness ventilation systemAir exchange and fresh air purification system: Oil-free clean gas source, multiple filtration (special polar and non-polar compositefiltration)Sealing and Positive Pressure Maintenance System: Special sealing technology and positive pressure maintenance in cabintopreventpollutants from enteringMulti-function on-line monitoring and protection function: omni-directional monitoring and remote control, comprehensive system protection functionEach cabin has independent temperature, humidity, pressure and flowsensors.Product Parameters Studio volume60LStudio300×500×400mm(width x depth x height)×4Exterior1.8×0.98×1.75m(width x depth x height)Temperature range15~70oC★Meet the requirements of plastic surface testing(60oC,5%R.H.)Temperature fluctuation≤ ±0.5oCTemperature uniformity≤±0.5oCTemperature resolution0.1oCTemperature controlIndirect temperature control method in constant temperature roomHumidity range3~80 % R.H.★Meet the requirements of plastic surface testing(60oC,5%R.H.)Humidity fluctuation≤ ±2% RHHumidity uniformity≤ ±2 % RHHumidity resolution0.1 % RHHumidity controlDry and moisture proportional control method (external)Formaldehyde background value≤0.006 mg/m3Individual VOC background value≤0.002 mg/m3TVOC background value≤0.02 mg/m3 Detailed Photos Company InformationFAQ1.Q :How to provide after-sales service?A:If customers need our engineers to come to the site for service, we will send out engineers to provide repair service for you.2.Q: Can we visit and study in your factory?A: Welcome to visit and study in our factory, we will show you our R&D and production capacity.3.Q :Can I install and commission the calibration equipment on site?A: Yes, we can send technicians and engineers to the customer's site for installation, commissioning and calibration.4.Q: What are the transportation methods?A :Air freight, sea freight, railroad transportation, all transportation methods according to the customer's needs.5.Q : What are the packing methods?A: Standard export wooden box packaging, solid and firm.6.Q :How do you calibrate the equipment?A: We have our own calibration and third-party calibration.7.Q :What are the payment methods?A :The payment methods are T/T, CIF, Paypal, L/C, VISA and so on.8.Q :How long is the warranty period?A :Warranty is 1 year, lifetime free service.9.Q :What is the delivery time for your company's products?A :This depends on the actual product you order, usually at least 30 days.
