Description

Technical Field

[0001] The invention belongs to the technical field of anti-static equipment in fireworks and firecrackers industry, and specifically relates to a long-acting anti-static medicine-related rubber plate workbench. Background Art

[0002] In order to prevent the hazards of static electricity during the production of fireworks and firecrackers, the work surfaces of fireworks and firecracker production enterprises have the following anti-static requirements: ① Level 1.1 anti-static workbenches and floors should be used, and the grounding resistance value should be between 5x104Ω-1x106Ω. Level 1.1 transit warehouses and warehouse floors should use anti-static floors, and their grounding resistance value should be between 5x 104Ω-1x 1010Ω. ② Anti-static work surfaces and floors should be flat, smooth, seamless, and dust-free. Anti-static rubber sheets should be seamlessly connected and dust-free. ③ Anti-static work surfaces should be laid with anti-static rubber sheets. The anti-static rubber sheets and grounding wires should be tightly connected by fixing bolts, etc., and the tight connection area should be greater than or equal to 20cm 2 The grounding wire should not be connected to the grounding wire of an independent lightning rod, and the distance between the grounding wires should be kept above 3m.

[0003] At present, most fireworks and firecracker manufacturers use PVC anti-static plastic board work surfaces, which poses a serious safety risk of insufficient and timely discharge of static electricity, and also has the following shortcomings:

[0004] Point 1: The existing PVC anti-static plastic plate workbench has a grounding resistance value of 1x106Ω-1x1010Ω, and its anti-static and static discharge capabilities are not strong, which does not meet the latest national requirements for the anti-static work guidelines for the fireworks and firecrackers industry, which are between 5x104Ω-1x106Ω.

[0005] Point 2: The existing PVC anti-static plastic board workbench has a structure in which the PVC anti-static plastic board and the work surface (wood or cement table) are not connected by adhesive (such as conductive glue), but the PVC anti-static plastic board is directly laid on the work surface without being fixed, and no conductive copper bar or copper foil structure is used in the middle to affect the further static leakage function. During use, the PVC anti-static plastic board and the work surface are prone to movement, and gunpowder is easily accumulated, which affects the safe production of fireworks and firecrackers.

[0006] Point 3: The existing PVC anti-static plastic board workbench table top is made of PVC plastic with conductive materials added and modified through filling. The material has poor rebound. When gunpowder or tools contact the workbench, it cannot effectively buffer and absorb energy, increasing the risk of gunpowder ignition and explosion. The conductive material in the PVC anti-static plastic board will continue to be absorbed over time, and the material's electrostatic conductivity will continue to decline, increasing the probability of electrostatic discharge caused by excessive static accumulation.

[0007] Point 4: The existing PVC anti-static plastic board countertops are affected by specific pharmaceutical processes such as alcohol contact corrosion and daily work surface washing. The PVC anti-static plastic board countertops are prone to physical damage such as surface aging, cracking, and breakage. Their resistance value increases, and their anti-static ability drops sharply. They need to be replaced regularly (generally no more than 3-6 months). Summary of the invention

[0008] The purpose of the present invention is to provide a long-lasting antistatic drug-related rubber plate workbench, which can minimize the risk of explosion of drugs in fireworks and firecrackers caused by static electricity accumulation and discharge.
