The salt spray test is a test that artificially simulates the salt spray environment. Compared with the exposure test under atmospheric conditions, it has significant advantages. The corrosion environment can be controlled and the environment has good reproducibility, which greatly saves the test time and human material resources. The salt spray corrosion test chamber can be used to evaluate the ability of materials and their protective layers to resist salt spray corrosion, and to compare the process quality of similar protective layers. It can also be used to evaluate the ability of certain products to resist salt spray corrosion. Salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume of space-the salt spray test box, using a manual method in its volume space to create a salt spray environment to evaluate the product's salt spray corrosion resistance quality The material used to manufacture this equipment is corrosion-resistant imported PVC plastic sheet, which does not affect the test results. In the design work of this equipment, the internal and external pressures are balanced, and the salt spray will not directly spray on the sample. And the design takes into account the top of the device, the inner wall and other parts will produce condensed water, therefore, during the test of this device, the condensed water will not drip on the sample and affect the test results. Large Health Industry, Rehabilitation Equipment lifting column is a kind of lifting column, It is usually used for furniture and Equipment such as writing desk, Table Lifting Equipment workbench, Lifting Table Customization, display cabinet, etc. It can be adjusted as required. It can be used for Health Equipment Customization. Improve work efficiency and comfort. According to different use needs and structural forms, lifting columns can be divided into the following categories: Lifting Column,Electric Lifting Column,Lifting Columns Telescopic,Telescopic Lifting Columns Suzhou Herstar Medical Technology Co., Ltd. , https://www.hosunherstar.com
1. Electric Lifting Column: The electric lifting column is a lifting column driven by a motor and its height can be adjusted by button control. Electric lifting column speed, good stability, easy to operate, suitable for frequent adjustment of the height of the occasion.
2 manual lifting column: manual lifting column is a kind of column by manually rotating the screw to achieve height adjustment, has the advantages of simple, reliable, economic, suitable for some occasions do not need to adjust the height frequently.
3. Pneumatic lifting column: pneumatic lifting column is a kind of column to achieve height regulation through air pressure. It has the advantages of fast speed, low noise, simple maintenance and so on.
