Is an ideal basic equipment required chemical industry, universities and research laboratories and other units used in the manufacture and analysis of experiments which concentrated, dry recycling. Characteristics of fiberglass: the average person's idea of ??glass as hard breakable objects, not suitable as a structural material, but as it pumped into the wire after, its strength has increased considerably and has flexibility, it gives shape with resin after finally become good The structural material. Glass fibers with a diameter smaller increase its strength. Glass fibers as a reinforcing material has the following features, these features make the use of glass fibers is more extensive than other types of fibers, also ahead of the pace of development of its properties are listed below: (1) high tensile strength, elongation small (3% ). (2) high elasticity, rigidity. Elongation (3) large and high tensile elastic limit strength, impact energy is absorbed so large. (4) inorganic fibers, with non-flammable, chemical resistance. (5) water absorption. (6) scale stability, heat resistance are good. (7) good workability, shares can be made, bunch, felt, fabric, such as different forms of products. (8) Transparent light transmitted through the structure: distillation flask, but a pear-shaped or round-bottom flask with standard ground interface, connected by a serpentine highly reflux condenser and vacuum pump, a reflux condenser and with another opening There is connected to the receiving flask grinding mouth for receiving the organic solvent was evaporated. Between the condenser and the vacuum pump with a three-way cock, and the atmosphere when the system can be distillation flask, then the flask was removed, the transfer of the solvent, when the system communicates with the vacuum pump, the system should be in minus overpressure condition. When used, it should be reduced, and then activate the motor rotates the distillation flask, when completed, should be shut down, and then through the atmosphere to prevent loss in the distillation flask rotation. As a distillation of the heat source, often with a corresponding constant temperature water bath. Electronically controlled rotary evaporator, the flask at the most appropriate speed, constant rotational speed in order to increase the evaporation area. By vacuum evaporation flask in the vacuum state. While the rotary evaporator flask placed in a constant temperature water bath heated solution bottle is heated under vacuum in a rotary evaporator flask diffusion. System may be sealed rotary evaporator under reduced pressure to 400 to 600 mm Hg; solvent distillation flask was heated with a heating bath, the heating temperature of the boiling point of the solvent accessible; but can also be rotated at a speed of 50 to 160 r / min, the solvent to form a film, increasing the evaporation area. In addition, under efficient cooler effect, superheated steam can be rapidly liquefy and accelerate the rate of evaporation. Fiberglass: Fiberglass is an excellent inorganic non-metallic materials. Principle rotovap: rotary evaporator under reduced pressure, mainly used in a large number of volatile solvent continuous distillation. In particular, for distillation receiving liquid extracts concentration and chromatographic separation of the reaction product can be isolated and purified. The basic principle is that a rotary evaporator under reduced pressure distillation, which is under reduced pressure, when the solvent distillation, distillation flask in continuous rotation. English formerly known as: glass fiber. Component is silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide and the like. It is a glass ball or waste glass as raw material of high temperature melting, drawing, winding, weaving and so the process. And finally the formation of various products, glass fiber filament diameter from a few microns to twenty meters microns, a human hair is equivalent to 1 / 20-1 / 5, each bundle fiber precursor, hundreds or even root Thousands of filaments composed of complex materials commonly used as a reinforcing material, electrical insulating materials and insulation materials, circuit boards, etc., it is widely used in various fields of national economy. |
