Main frame: aluminum alloy profile frame is adopted, column is φ 50mm * 2mm aluminum alloy round pipe profile, cross beam is 34mm * 34mm * 2mm aluminum alloy square pipe profile, and connector is high-strength nylon plug-in of special laboratory for mold development. The surface shall be treated with anti-oxidation treatment, and then the epoxy protective layer shall be sprayed with electrostatic powder for anti-corrosion surface treatment. The adhesion of the sprayed epoxy protective layer shall pass the falling object impact test; the static bearing capacity of the frame shall be more than 150 kg; the frame structure shall be reasonable, flexible, and stable, and can be combined according to the customer's requirements; the main steel frame can be directly suspended from the cabinet without damaging the laboratory Walls and floors.

Table top: a. the physical and chemical veneer adopts 25mm thick domestic high-quality environmental protection type medium fiber board as the base material, and the imported 0.9mm-thick Chemsurf physical and chemical board with pressure and acid-base resistance is adhered on the surface. The cross-section around the table top is treated with domestic high-quality 2.0mm-thick PVC edge sealing and water-proof, with beautiful and smooth appearance. The solid psychological board adopts 12.7mm imported solid psychological board, the surrounding edge is thickened to 25.4mm, and the edge is rounded and polished, which conforms to the ergonomic design, and has the characteristics of acid and alkali resistance, corrosion resistance, impact resistance and toughness. The 13 mm thick Trespa laboratory panel imported from Holland is adopted for Qiansi board. The edge around it is thickened to 26 mm. The edge is rounded and polished. It conforms to the ergonomic design and has the characteristics of anti impact, acid and alkali resistance, corrosion resistance, scratch resistance, easy cleaning, UV resistance and static resistance. The epoxy resin board is made of epoxy resin, quartz sand, curing agent and pigment by one-time die pressing. It is resistant to high temperature and strong corrosion for 24 hours. It is absolutely moisture-proof and repairable. The more severe the experimental conditions are, the more outstanding the performance is.
