The invention combines the advantages of various modified starches, has the advantages of strong size film strength, transparency, good water absorption, good dispersion, good gliding property, low gelatinization temperature, strong paste liquid bond force, good adsorbability, easy dissolution, good film forming ability, weak retrogradation, good elasticity, smoothness, flexibility, tough and elastic size film, nontoxicity, tastelessness, safe use, convenient operation, large production scale, little investment, low energy consumption, less pollution, high productionefficiency, stable and reliable product quality and the like and is widely applied to gypsum products.

The invention provides a clean preparation method of layered composite metal hydroxides (LDHs), which uses metal hydroxides, metal soluble salts and metal basic carbonates as reaction raw materials, and directly synthesizes high-purity, Regularly structured layered composite metal hydroxides. Since only metal hydroxides, metal soluble salts and metal basic carbonates are used as reaction raw materials in the reaction process, NaOH or NaOH or NaOH commonly used in traditional processes are not used. 2 CO 3 Alkaline raw materials can greatly reduce the alkalinity of the reaction product, avoid multiple washings with a large amount of water, save a lot of water resources, and protect the environment; The method is a clean preparation method in which a substance or an oxide is used as a reaction raw material, the reaction temperature of the method is lowered, the reaction time is shortened, the reaction condition is mild, the production cost and energy consumption are low, the requirements for the reaction device are low, the equipment investment is small, the process flow is simple, and basically no Environmental pollution is an environmentally friendly process.

The invention relates to a composite material injection molding forming technology. An existing injection molding forming technology is optimized and improved, metal powder of Ti, Mg, Al, Ni, Mo and other components and matrix resin are utilized as composite material raw materials, the multi-sprayer intermittent injection molding manner is adopted, under the technology conditions of the injectionmolding pressure, the temperature, the time and the like obtained through repeated tests, finally-obtained plastic products have good mechanical performance, and the technical characteristics that fewsurface defects exist, the glossiness at 60 DEG C is larger than 80%, and cost and energy consumption are low are achieved.

The invention provides an oil displacement composition, a multi-element thermal fluid oil displacement composition containing the same and a displacement method. The oil displacement composition comprises the following components in percentage by weight: 10-45% of ammonium hydrogen carbonate, 0.3-10% of high-temperature foaming agent, 0.2-5% of high-temperature oil displacement agent and the balance of water. The multi-element thermal fluid oil displacement composition provided by the invention comprises the oil displacement composition and water vapor, wherein the mass ratio of the oil displacement composition to the water vapor is 1:(20-100). The multi-element thermal fluid displacement method provided by the invention comprises the following step of: injecting the multi-element thermal fluid oil displacement composition into a heavy oil reservoir through an injection well in an injection-production well group. The multi-element thermal fluid oil displacement composition provided by the invention has low preparation cost and lower energy consumption; a replacing technology after vapor injection into the heavy oil reservoir is formed by combining the displacement technology; and the replacing technology has synergistic effects such as displacement control, quick supplement of stratum energy, improvement of underground seepage capability of fluid and the like so as to improve the crude oil recovery rate.
