It can protect the eyes from radiation, relieve eye pain, nourish eye nerves, accelerate blood circulation in the eyes, and replenish water. Function, safe and healthy, long-term use will not cause harm, and the preparation process is simple, low cost, easy to use, and suitable for popularization.

The invention discloses an in-situ soil remedying composite material capable of efficiently removing heavy metals. The in-situ soil remedying composite material comprises the following components: 10-20 parts of sodium persulfate, 5-10 parts of sodium polyepoxysuccinate, 1-5 parts of polyvinylpyrrolidone, 1-3 parts of nanocarbon, 1-5 parts of serpentine, 5-10 parts of lignite humate, 1-3 parts ofa surfactant, 4-8 parts of calcium dioxide, 4-8 parts of Chinese herbal residue, 1-3 parts of potassium permanganate, 1-5 parts of red mud particles, 1-5 parts of chitosan dithiocarbamate and 1-3 parts of methacryloyloxyethyl trimethylammonium chloride. The in-situ soil remedying composite material can remedy soil contaminated by various heavy metals (such as Pb, Cd, Cu, Zn, Cr and As) and toxic organic substances (such as chlorinated organic compounds, brominated organic compounds and antibiotics), reduces conditions of strong heavy metal activity and strong bioavailability in the soil, prevents transfer of the heavy metals from the soil to plants, prevents bioenrichment and amplification of the heavy metals, can efficiently remove the heavy metals such as chromium and mercury from the soil, and restores original functions of the soil, so that needs of agricultural development are met, and the ecological safety of crops and other plants is guaranteed, and the ecological risks of the bioamplification and the enrichment of the heavy metals to people are avoided.

The invention discloses an 800-MPa medium-carbon high-silicon cold-rolled galvanized sheet and a preparation method thereof. The method comprises the following steps: hot rolling, cold rolling and galvanizing. The sheet comprises the following components in percentage by weight: 0.16-0.20% of C, 1.6-2.0% of Mn, at most 0.010% of S, at most 0.020% of P, 0.05-0.30% of Si, at least 0.025% of Als, 0.20-0.30% of Cr, 0.010-0.050% of Ti, and the balance of Fe and inclusions within allowable range. The contents of carbon and silicon are properly enhanced, and proper amounts of titanium and chromium are added. Compared with the low-carbon alloy formula by adding molybdenum and chromium, the cost is obviously reduced, and the production difficulty is lowered; and on the premise of enhancing the carbon content and silicon content, the galvanizability of the galvanizing technique is ensured. The enhancement of the contents of carbon and silicon and addition of proper amounts of titanium and chromium mainly aim to enhance the hardenability of steel and lower the Ac3 line, so that the CCT curve of steel shifts rightwards, and the Bs and Ms transition temperature is lowered. The method prevents all austenite from being converted into bainite, and ensures the martensite ratio in the galvanized product to be higher than 15%.
