Melting method and system for injection molding materials, and information processing terminal

Abstract

The invention belongs to the technical field of high polymer materials, and discloses a melting method and system for injection molding materials, and an information processing terminal. The melting method comprises the steps that drying is conducted, specifically, polybutylene terephthalate with the mass percentage being 70% is dried at the temperature of 150 DEG C; melting is conducted, specifically, the polybutylene terephthalate is melted at the temperature of 230-240 DEG C; annealing is conducted, specifically, hot liquid media of hot water, hot mineral oil, hot glycerin and other liquidare heated to the temperature which is 20-35 DEG C higher than the product using temperature or the temperature which is 25-35 DEG C lower than the heat distortion temperature of products, and the products are put into the hot liquid media to be annealed; and batching is conducted, specifically, high-density polyethylene with the mass percentage being 30% is added at the temperature of 240-250 DEGC. The injection molding products produced through the melting method have the stable chemical properties, and the degradation phenomenon is prevented.

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...

AI Technical Summary

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
