How to properly control the selection of waste plastic additives?

In order to improve the quality of recycled products as much as possible, it is necessary to re-add a certain amount of additives in the process of remanufacturing to improve the molding processing, mechanical and thermal power generation of waste plastics. The finished additive can not only play a neutral and efficient role, but also increase the value of waste plastic components to achieve the purpose of comprehensive utilization. We should pay attention to the choice of additives.
So how to properly control such additives? In fact, nothing more than waste plastic additives to control a certain amount, but also should take into account the plastic composition, which is relatively simple, but it requires us to fully understand the knowledge of waste plastics, so that it is good Add and use. Here, China Plastics Network summarizes the following principles for the selection of waste plastic additives:
The choice of additives is determined according to the variety of plastics and the degree of aging, etc., the choice of additives:
1. Polyolefin new materials generally only add a small amount of additives during processing and molding, such as antioxidants, UV absorbers, etc. When the waste is recycled, generally only a small amount of coloring agent can be added, so the formula is not difficult to determine. Unless such plastics are severely aged, hard and brittle, the composition of the ingredients needs to be determined on a case-by-case basis.
2, the composition of PVC plastic is relatively responsible, especially soft polyvinyl chloride, containing a wide variety of additives, plasticizers, stabilizers, UV absorbers, lubricants and pigments, among which plasticizers Mainly, the most used. The products are affected by climatic conditions such as light and heat during use. The plasticizer gradually oozes out, and the product hardens, especially its physical properties are greatly reduced, gradually aging, and can not meet the requirements of use and become waste. When recycling such waste products, a sufficient amount of plasticizers and other auxiliaries must be added to maximize the recovery of mechanical properties, because it is important to determine the formulation reasonably.
3. The amount of plasticizer added is mainly determined by the hardness required for recycled polyvinyl chloride products. Therefore, the ratio of hard and soft in recycled PVC waste products should be considered. The amount of plasticizer in soft products such as PVC film, artificial leather and wallpaper is very different from that in rigid pipes and profiles. Therefore, as long as the hard and soft recovery rates are mixed with each other, adjustment is made. By blending the two, it is possible to produce a recycled product of the required hardness, which can reduce the amount of plasticizer, even without plasticizer.
Use additives:
1. Because of the lower price of waste plastics and recycled products, the additives used are also cheaper.
2. Because waste plastics are often a mixture of various color wastes, dark colorants are generally added during reprocessing, so the appearance and color of the selected additives are not high.
3. The additive should meet the certain performance requirements of the recycled product.

The Tinhy's Geocell of geosynthetic cellular confinement system is a matrix of lightweight, expandable and flexible thermoplastic strips that are ultrasonically bonded to form a strong, dimensionally stable and inert honeycomb structure.

The  geocell is honeycombed three-dimensional grid structure which is welded by high-strength HDPE sheet. The  geocell is easy to stretch. It can be folded up when transport and opened to fill the earth or concrete when use it. It will constitute a strong lateral and large stiffness of the structure when use it. In the geotechnical engineering, soil, sand, stone, concrete and other fill together constitute a different cohesion, different reinforcement strength, different depth of the cushion. The cushion can be placed in the required position accordance with the requirements of the project for Reinforcement of roads, railways and soft soil foundation, slope protection, green structure, the construction of retaining walls and so on. The most important feature is can solve and complete a variety of difficult problems which can`t be dealed with use conventional method in geotechnical engineering,such as bridge jumping, soft base subsidence, fouling, landslides and desert subgrade.
