Case overview: polyurethane material is a new organic polymer material, known as "the fifth largest plastic", because of its excellent performance, it is widely used in many fields of national economy. The application fields of products include light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation, etc.
Overview of polyurethane materials:
Polyurethane is the abbreviation of polyurethane, whose English name is polyurethane. It is a kind of polymer material. Polyurethane is a new organic polymer material, known as "the fifth largest plastic", because of its excellent performance, it is widely used in many fields of national economy. The application fields of products include light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation, etc.
Polyurethane material dryer:
SZG double cone vacuum dryer is a new generation of drying device developed by our factory in combination with the domestic similar product technology. The double cone vacuum adopts the belt chain two elastic connection mode, so the equipment runs smoothly. The specially designed process fully embodies the good concentricity of the two shafts. The heat medium and vacuum system adopt reliable mechanical seal or rotary joint of American technology. On this basis, we developed szg-a, which can not only stepless speed regulation, but also constant temperature control.
As a professional drying equipment manufacturer, our products are available from high temperature heat transfer oil as heat medium, medium temperature steam and low temperature hot water. When drying sticky materials, our factory will specially design a "copy board" mechanism or set ball bearings in the tank for you.
Principle of polyurethane material dryer:
SZG double cone rotary vacuum dryer is a double cone rotary tank body. The middle of the equipment is cylindrical, and both ends are conical. One end of the conical top is designed as an open feeding (also as a manhole), and the other end is a butterfly valve discharge. There are three layers inside and outside the tank. The heating medium of the jacket in the middle can be steam, circulating hot water or heat transfer oil, and the insulation layer is medium alkali ultra-fine glass wool, which consumes little energy; materials are put into the inner layer. The proper drying temperature can be selected according to the different physical properties of materials. Generally, variable temperature drying method can be used. In the early stage of drying, the temperature is low, and the temperature is gradually increased to increase the drying rate. When vacuum pumping and heating are started, the drying speed is slow. When the material is heated to the vaporization temperature of water, the drying speed will be suddenly accelerated. The material will be heated to the vaporization temperature under the corresponding pressure within the allowable temperature range, and a large amount of vaporization will be vaporized. At this time, the material temperature will remain unchanged, and the heat added will be used for the heat of vaporization and various heat losses. The vacuum system will continuously discharge the vaporized steam and keep it The pressure difference between the evaporation surface and the space makes the drying continue. When the moisture content of the material is reduced to a certain extent, the water evaporated from the material is reduced.
Advantages of polyurethane material dryer:
Heat energy (such as hot water, low-pressure steam or heat transfer oil) is introduced into the closed interlayer, and the heat is transferred to the material to be dried through the inner shell.
Driven by power, the tank rotates slowly, and the materials in the tank continuously mix, so as to achieve the purpose of strengthening drying.
The material is in a vacuum state, and the water (solvent) on the surface of the material is saturated and evaporated due to the drop of vapor pressure, which is discharged by the vacuum pump in time for recovery. The moisture (solvent) in the material continuously permeates, evaporates and discharges to the surface, and the material achieves the drying purpose in a short time.
The solvent (water vapor) evaporated after heat absorption of wet materials is extracted by vacuum pump through vacuum suction pipe. In order to achieve the purpose of recovery, the production cost is saved, the working conditions of vacuum pump are improved, and the environmental pollution is reduced.
