The invention discloses a method for preparing inorganic mineralized microcapsules based on droplets obtained after crystal nuclei in ethanol are dissolved in water. The method is as follows: 1. Sodium carbonate or dipotassium hydrogen phosphate is configured into a saturated aqueous solution, and the saturated solution is injected into the ethanol solution and vigorously stirred for 3 to 12 hours until the crystals of sodium carbonate or dipotassium hydrogen phosphate are evenly distributed in the ethanol ; 2. Dissolve calcium iodide in ethanol to form a calcium iodide-ethanol solution; 3. Take 1-4 mL of ethanol solution of sodium carbonate or dipotassium hydrogen phosphate crystals and mix with 1-4 mL of ethanol solution of calcium iodide , Add 2~10mL of water to form a precipitate; 4. Use natural sedimentation or centrifugation to wash the precipitate to obtain calcium phosphate or calcium carbonate microcapsules. The method is simple, highly repeatable, and has loose requirements on experimental conditions, and can realize drug loading and pH-regulated release.

The invention discloses a bromine-free bread and a production method thereof, which is prepared by compounding enzyme preparation, emulsifier, vitamin C, calcium iodide, thickener and filler. In this formula, vitamin C and calcium iodide are used to replace potassium bromate, which reduces the potential safety hazard in production, and at the same time, there is no harm to the human body caused by residual potassium bromate in bread. The invention can effectively improve the operability of the dough, improve the softness of the bread during bread making, increase the nutritional value of the bread, and supplement the intake of human vitamins and iodine.

The invention discloses a wear-resistant PVC hose, which consists of the following components in parts by weight: 30-60 parts of PVC resin; 2-5 parts of polytrimethylene terephthalate; 4-5 parts of calcium iodide; 2-4 parts of potassium phosphate; Turpentine 0.4-0.6; silicone rubber compound 2-5; styrene-butadiene rubber 10-15; carbon black 1-3; paraffin 1-2. The high-toughness polyvinyl chloride pipe of the present invention uses silicon carbide whiskers, which can effectively strengthen the internal structure of the pipe, and improve the mechanical strength and toughness between the pipes. In addition, it improves the aging resistance of the pipe; the lubricant can make the material more uniform during the production process, improve the smoothness of the extrusion, and also play a role in enhancing the internal structure. The prepared polyvinyl chloride pipe has the characteristics of high toughness and high mechanical strength.

The invention discloses a solution-based method for growing cesium iodide single crystal flakes. The solubility of cesium iodide in dimethyl sulfoxide (DMSO) tends to decrease as the temperature rises. Heating the cesium solution can obtain the seed crystal, and then put the seed crystal into a special glass device to grow to obtain a cesium iodide single crystal flake with better quality. The invention has the advantages of convenient operation, low raw material cost, and high-quality cesium iodide single-crystal flakes can be precipitated from the cesium iodide solution. The invention adopts the combination of the solution precipitation method and the mold constraint control method, and can prepare the cesium iodide single crystal flake with controllable size, excellent light transmittance and light extraction efficiency. The cesium iodide single crystal flake grown by the present invention has high quality, high transparency and unique photoluminescent performance. The single crystal flake prepared by the preparation method can be matched with a silicon-based photodiode to produce a flat-panel X-ray detector with excellent performance. device.
