Problems solved by technology

[0004] (1) The products produced by the existing injection molding material melting process are easy to degrade or are easily changed by external interference, which cannot meet the needs of producers
[0005] (2) The drying time of polybutylene terephthalate is longer, which reduces the drying rate and increases energy consumption
[0006] (3) In the polybutylene terephthalate spectrum peak-finding method, commonly used methods are simple comparison method, first-order derivative method, second-order derivative method, third-order derivative method, symmetrical zero-area transformation method, etc.; wherein The simple comparison method can only be used to find simple peaks, not suitable for finding heavy peaks
The first-order derivative method is also not suitable for the resolution of heavy peaks, the sensitivity of the second-order derivative method is not enough, the third-order derivative method is easy to identify false peaks, and the transformation width of the symmetrical zero-area transformation method is not easy to confirm

Abstract

The invention belongs to the technical field of polymer materials, and discloses a method and system for melting injection molding materials, and an information processing terminal, including: drying: drying polybutylene terephthalate with a mass percentage of 70% at 150°C . Melting: melting the polybutylene terephthalate at 230-240°C. Annealing: Use a hot liquid medium such as hot water, hot mineral oil, hot glycerin, etc., to heat the product to a temperature 20-35°C higher than the product's service temperature or 25-35°C lower than the heat distortion temperature of the product, and put the product in Perform annealing treatment. Ingredients: 30% by mass of high-density polyethylene is added at 240-250°C. The injection molded product produced by the process of the invention has stable chemical properties and prevents degradation.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a method and system for melting injection molding materials, and an information processing terminal. Background technique [0002] At present, the processing technology of molding or casting can obtain parts of the same size in large quantities, so it plays an important role in the field of processing and manufacturing. The development of the automobile industry is inseparable from the development of the molding process. Since the automobile industry needs to manufacture parts of the same specification in large quantities, it relies heavily on the molding process. With the development of technology and the change of people's ideas, many non-metal parts appear in auto parts. Among them, the dominant material of non-metal parts is plastic parts, which are easy to process, easy to install and light to use, so they are more and more favored by the automobile in...
