Summary Report on the Production of Modified Materials Using Recycled Materials

Thread Content

This is my work summary report for over a year; due to technical confidentiality reasons, only part of it can be made public. Those who are interested can communicate with me privately. Starting from last July, under the pressure of market price competition, we began conducting feasibility research and development tests using recycled materials for all our products. By August of this year, all three phases of testing, prototype development, and mass production had been completed. The products in question ranged in weight from 20 grams to 7 kilograms, and their dimensions varied from 200*150 to 2000*700. A total of 270 tons of recycled materials were used, without any quality issues arising. As is well known, among various types of recycled materials, PP material has relatively poor stability; therefore, the risk associated with using it to develop and produce modified materials is quite high. Especially when used to produce high-performance materials. I will now write down some things that could be considered experience; perhaps they will be useful to those who need to do something similar to what I do. Please forgive me, but I cannot write down the specific technical methods here. 1. Selection of recycled materials: When it comes to choosing recycled materials, people generally prefer those with relatively high overall performance, stable color, and a low number of recycling cycles. Our choices differ to some extent; when making decisions, we never considered the performance, color, or number of times the recycled material has been reused, as these factors are extremely difficult to control. We simply chose a reliable supplier and asked them to provide us with all the recycled materials. 2. The mindset toward choosing recycled materials: As the saying goes, greed leads to trouble; reason is more important when making choices. A small act of greed can make the use of recycled materials extremely difficult. Make choices with your reason to carry out your work smoothly. 3. Selection of modifiers: In fact, there’s not much to say about the selection of modifiers – there are only a few types available in total, and it’s always the same ones over and over again. The key issue is whether one can break away from the mindset of using existing raw materials and think creatively to develop new ways of utilizing them. 4. Selection of additives: I remember that one of the first difficulties encountered at the beginning of the R&D process was related to additives – certain additives that were completely unknown to the company’s existing technical staff and procurement personnel. It was very difficult to discuss these additives, to the point where the procurement department refused to purchase them. By combining various additives in appropriate ways, we were able to improve the overall performance of the materials. 5. Formulation design: When designing the formulation for the recycled material, considerations include the extent to which the overall properties of the recycled material can be adjusted, the likelihood that additives or modifiers will participate in chemical reactions, and the ratio of various materials used, which may go beyond conventional approaches. The series of formulations we ultimately developed have overall performance that is virtually identical to that of the modified materials produced using raw materials, yet the material cost has decreased significantly.
