The salt spray corrosion test chamber is one of the "three preventions" (damp heat, salt spray, mold) test equipment for artificial climate environment. An important test equipment. The salt spray corrosion test chamber must pay attention to the following items during installation: 1. Installation of water supplement system for salt spray corrosion test chamber 1. Water quality requirements: install filters for industrial water or tap water (the pH of the filtered water is between 6.5 and 7.2) or purified water (mineral water contains minerals and cannot be used) 2. Pressure requirement: The water pressure is 1 ~ 3 kg to ensure the normal water supply. 3. Interface requirements: The water supply port of the equipment needs to be connected with a hose and fixed with a sealing ring to prevent leakage. Second, the salt spray corrosion test box power supply system requirements 1. Power requirements: single-phase AC 220V 50Hz 2. Current requirement: Max 15 A 3. Protection requirements: need to install an independent leakage protection switch 3. Installation of the air intake system of the salt spray corrosion test chamber 1. Pressure requirements: air compressor or air supply pipe pressure ≥ 3 kg, and dry and clean 2. Interface requirements: The equipment uses quick connectors to facilitate disassembly and maintenance 3. Time requirement: when the equipment is working normally, the gas source must be supplied for a long time without interruption. 4. Requirements for the exhaust system of the salt spray corrosion test chamber 1. Material requirements: PVC polyethylene material (corrosion resistance) must be used 2. Interface requirements: The exhaust port of the equipment should be connected by a hard tube, and sealed with a sealant to prevent air leakage. 3. Drilling requirements: the equipment is naturally exhausted, and the height of the wall opening must be slightly higher than the exhaust hole to ensure that the gas flows back to the laboratory after condensation 5. Installation of drainage system for salt spray corrosion test box 1. Drilling requirements: the equipment is naturally drained without pressure, and the height of the wall opening must be lower than the drain to ensure normal drainage 2. Interface requirements: hoses or rigid pipes should be used to connect the equipment drains, and use sealing rings to prevent leakage. Attachment: Cautions for site installation of the salt spray corrosion test chamber: no precision instruments in the laboratory, flat ground, no direct sunlight, and indoor ventilation. Concealer that is too light or too dense will make your makeup look unnatural. Therefore, you should choose different concealer according to your skin type to make your skin appear healthy. Paste and strip concealer have better covering effect, but the operation is more difficult; The concealer with low concealing ability can make the makeup natural because of its fresh texture. Generally, concealer is solid, but its viscosity is different. According to your own needs, you can choose to use large areas or local products.
