Use of a compound, microarray chip substrate, microarray chip and use and method thereof. The present application provides use of a compound, or a geometric isomer, tautomer, isotopically labeled, hydrate, solvate or salt thereof in chip surface modification. Also provided is a microarray chip substrate modified by the compound, and a microarray chip comprising the microarray chip substrate. The microarray chip substrate of the present application can greatly improve the surface modification function by surface modification, improve nucleic acid synthesis yield, amplify detection signal, and avoid non-specificity and cross-talk. It has a wide application prospect.

This utility model discloses a lead-acid battery electrode plate processing device, including a transmission component, a spraying component, an air-cooling component, and a collection box. The transmission component is suitable for sequentially hoisting and transporting lead-acid battery electrode plates one by one. The spraying component includes a drive mechanism and a nozzle. The nozzle is connected to sulfuric acid to form a spray. The input end of the drive mechanism is connected to a sulfuric acid source, and the output end is connected to the nozzle. The air-cooling component is configured to supply air to the surface of the electrode plate after the electrode plate receives the sulfuric acid spray. The collection box is located below the electrode plate and is suitable for receiving dripping sulfuric acid. This solves the problem of floating powder on existing electrode plates posing a health hazard to workers.

The invention belongs to the technical field of agriculture, and discloses a preparation method and application of an environment-friendly full-biodegradable mulching film, and the preparation method of the environment-friendly full-biodegradable mulching film comprises the following steps: S1, preparing raw materials; s2, mixing the raw materials; s3, adding an auxiliary material; step S4, mixing and plasticizing; s5, extruding to form a film; step S6, cooling and traction; and S7, rolling and packaging are conducted. The full-biodegradable mulching film prepared by the invention has good mechanical properties and heat-preserving and moisture-preserving effects, can be quickly degraded in a natural environment, and does not cause negative effects on the environment; meanwhile, the raw materials of the mulching film are from renewable resources, so that waste recycling is realized, and the requirement of sustainable development is met.
