2results about How to "Addressing Insufficient Absorption" patented technology

This utility model relates to the field of wind and sand control technology, specifically an ecological environment wind and sand control and greening protection device, including a water storage tank and a matching guide bucket cover. The water storage tank has an inner cavity for water storage, with multiple connection holes. A hollow tube is detachably connected to the inner cavity through these connection holes. A water-guiding part is placed on the outer surface of the hollow tube. One end of the water-guiding part passes through the hollow tube and connects to the root system of the planted sapling, while the other end is placed in the water within the inner cavity. The water-guiding part guides the water stored in the inner cavity of the water storage tank to the root system of the planted sapling. This utility model, by employing multiple connection holes and a hollow tube, can selectively protect a number of planted saplings. Simultaneously, the hollow tube ensures the wind resistance of the sapling trunks. Furthermore, the water-guiding part helps the roots maintain sufficient water absorption during the early stages of sapling planting, when their water absorption capacity is poor due to their inability to adapt to sand.

The invention provides a production method of nickel-chromium alloy nodular cast iron which is QTNi2Cr0.55 and comprises the following chemical components in percentage by weight: 3.65-3.85% of C, 2.6-2.8% of Si, less than or equal to 0.2% of Mn, less than or equal to 0.06% of P, less than or equal to 0.02% of S, 2.0 + / -0.1% of Ni, 0.55 + / -0.1% of Cr, 0.45-0.65% of Mg and the balance of Fe. A high-carbon low-silicon nodular cast iron production process is adopted, nickel supplementation is achieved while nodulizing is completed through a nickel-magnesium nodulizing agent, chromium supplementation is achieved by adding low-carbon ferrochrome into a casting ladle, the characteristics of pretreatment deoxidation of a silicon-calcium inoculant, graphitization of a silicon-strontium inoculant, long-acting inoculation of silicon-barium and the like are fully utilized, one-time bag burying inoculation is achieved, and the production efficiency is improved. And insufficient impact inoculation absorption is avoided, the appearance of carbides is effectively avoided, the pearlite content is greatly reduced, and the comprehensive performance of the casting is improved.
