Electrical control components: “Schneider” and “Omron” components are used to better control the temperature, refer to the picture.Science of the Total Environment 671 (2019) xxxĬontents lists available at ScienceDirect Control method: thermal balance temperature adjustment method ĥ. Temperature sensor: PT100 platinum resistance temperature tester Ĥ. Temperature controller: Panasonic PLC, human-machine touch screen adopts Taiwan Weinview ģ. The original imported Japanese Panasonic PLC, ozone concentration controller, matched with the British imported ozone concentration sensor, can accurately detect and control the ozone concentration, and can control the ozone concentration deviation to ≤5% (the national standard requires ≤10%) Ģ.
Heater: stainless steel 316LI fin-type special electric heating tube equipped with four universal runners to facilitate the movement of the box.ġ. The viewing glass has an electric heater to prevent condensation and defrost.Ħ. The box door is equipped with a conductive film insulating glass observation window, and the size of the observation window is 200×300mm. Door locks, hinges and other hardware accessories are imported from Japan “TAKEN”.ĥ. Imported sealing materials and unique silicone sealing structure are used between the door and the door frame, and the sealing performance is good.Ĥ. The insulation material between the inner box and the outer box is high-quality ultra-fine glass fiber insulation cotton, which has a good effect on cold or hot insulation.ģ. According to the temperature requirements of the laboratory, the thickness of the insulation layer is designed as: 100mm.Ģ. The entire box shell is made of 1.2mm cold plate by electrostatic spraying of CNC machine tools, and the color is beige the inner wall material of the laboratory is SUS304 high-grade anti-corrosion stainless steel plate, with reasonable structure design, sophisticated manufacturing process, and beautiful interior and exterior.
Sensor: The ozone concentration sensor imported from the UK can achieve precise controlġ2. Ozone source: ozone generator (using voltage silent discharge tube to generate ozone)ġ1. Sample rack speed: 360 rotating sample rack (speed 1 rpm)ġ0. The ozone produced by this series of test chambers can be used for the aging test of non-metallic materials and organic materials (coatings, rubbers, plastics, paints, pigments, etc.) under ozone conditions.Ģ. Inclined Surface Coefficient Of Friction TesterĮxternal pressure: standard atmospheric pressure.Medical mask protective & clothing testing machines.
