Resin usually refers to organic polymers that have a softening or melting range after being heated, and have a tendency to flow under external forces during softening. At room temperature, they are solid, semi-solid, and sometimes liquid. In a broad sense, any polymer compound that can be used as a raw material for plastic product processing is called resin.
The relative molecular weight is uncertain but usually high, and it appears as a solid, medium solid, pseudo solid, or sometimes liquid organic substance at room temperature. Has a softening or melting temperature range, has a tendency to flow under external forces, and often fractures in a shell like shape. Broadly speaking, it refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents. According to their sources, they can be divided into natural resins and synthetic resins; According to their different processing characteristics, there are thermoplastic resins and thermosetting resins.
The RL type melt granulator utilizes the characteristic that the melting point of the material is lower than 250 ℃. Based on the viscosity range of the material in the molten state, a special fabric device is used to evenly distribute the molten liquid on a steel strip that moves uniformly below it. Under the cooling effect of a continuous spray device set below the steel strip, the material is cooled, solidified, and packaged during transportation, thereby achieving the purpose of granulation molding.
This product is a new type of (melting) forming granulator. The work changes from liquid to solid through transportation and cooling, and materials with a melting point range of 50 ℃ to 300 ℃ can be granulated and formed. No dust, improved production environment; And it has certain economic value (energy-saving, packaging container economy), fast product replacement, aesthetically pleasing granular products, uniform nearly hemispherical granular, and no thermal stress; Granular products are easy to package, transport, and store, as well as convenient for users to measure, mix, or remelt, and can be produced continuously. From feeding to packaging, it reduces physical labor, has stepless speed regulation, adjustable flow rate, and easy operation. Widely used in industries such as petroleum and fine chemicals. One machine can be used for making strips, pieces, and sheets; Toxic materials can be sealed in a lump.
