A precision-casting mold material for ornament consists of hydrogenated microcrystalline wax, paraffin, petroleum resin, high-molecular polymer, mineral wax and animal and vegetable wax. It has better bending strength, surface hardness, thermal stability, fluidity, reutilization and less linear shrinkage rate. It can be used for gold and silver ornaments.

The invention relates to a kind of impregnation enveloping wax combination used for electronic components, which contains petroleum wax, petroleum resin, and adhesion promoter. The impregnation enveloping wax of the invention has the advantages such as high drop melting point, excellent high-temperature property, fine electrical property, low melting viscosity, good adhesivity, fine moisture resistance, and so on. Coil impregnation-enveloping materials for exclusive use to existing technology electronic components all take resin as main materials, and the impregnation-enveloping materials have higher cost. The impregnation encapsulating wax of the invention adapts to the impregnation and envelopment of inductance coil, mid-frequency and high frequency electric coil, and other electronic components.

The invention discloses aeroengine turbine guide vane polishing protection wax and a polishing method. The aeroengine turbine guide vane polishing protection wax is prepared from petroleum wax, abietic resin, hydrocarbon cream, a butylene polymer and the like by mixing processing according to a specific ratio. The aeroengine turbine guide vane polishing protection wax has good plasticity, good adhesiveness, appropriate physical and chemical performances and excellent use performances, is convenient for knife coating, can be removed easily, does not produce corrosion, toxins and pollution, and is environmentally friendly. The polishing method adopting the aeroengine turbine guide vane polishing protection wax comprises the following steps of protecting an air-guiding hole of a turbine guide vane by the aeroengine turbine guide vane polishing protection wax, carrying out polishing processing, and then removing the aeroengine turbine guide vane polishing protection wax. The polishing method can effectively prevent that metal chips block the air-guiding hole in turbine guide vane polishing.

The invention relates to an insulation impregnated coating wax-sealed compound which comprises: petroleum wax, macromolecule wax, malthene and gelatin.

The invention relates to an antique processing technology of an environment-friendly solid wood furniture decorative board, which utilizes raw lime to burn and soak the processed board to complete the coloring and insecticidal sterilization of the board. Specifically, the decorative board is soaked in a warming pool with raw lime and water for boiling. The processed boards can be made of high-grade furniture, decoration materials, indoor wooden doors, and musical instruments by burning and soaking raw lime. The invention is guided by the awareness of environmental protection advocated by the state to protect people's health from damage, so that indoor furniture and decorative materials do not release harmful gases and odors. The board does not change shape, does not crack, and increases the material density. The colors are mostly red, yellow and black, and it is an environmentally friendly new material with the characteristics of the original texture that is getting brighter and brighter.

The invention discloses a processing method of Chinese chestnut treated with sugar water, comprising the following steps of: (1) selecting raw materials; (2) preparing red bean sugar water; (3) soaking; (4) unshelling; (5) cutting with a knife; (6) candying; (7) canning; (8) preheating; (9) can sealing; (10) sterilizing; and (11) storing. In a production processing process of the Chinese chestnut, no chemical additive is added, original taste and nutritional value of the Chinese chestnut are guaranteed, no harm is done to physical health of human; red bean is delicious food and panacea used for treating diseases by doctors, traditional Chinese medicine shows that the red bean is sweet, acid and mild in smell and non-toxic, has the effects of resolving dampness and tonifying spleen, is applicable to people weak in spleen and stomach and is frequently used for treating hypertension, atherosclerosis and edema caused by various reasons as well as relieving summer heat, removing fever, detoxificating and invigorating stomach in food therapy, the Chinese chestnut is cooked in red bean sugar water, taste of the Chinese chestnut is enriched, and nutritional value of the Chinese chestnut is enhanced.
