The country’s support for rural areas is increasing. In rural areas, the sewage treatment facilities for septic tanks and toilets in rural areas are not perfect. Sewage septic tanks and public toilets in farms lead to odor, fecal agglomeration, and partial discharge of sewage. Some higher questions. Hunan Zhongke New Materials produces and manufactures high-quality septic tank products in response to the need for rural toilets to reform, and uses new composite material septic tank products to solve this problem.
Among them, PA has the advantages of excellent mechanical properties, corrosion resistance, oil resistance, heat resistance, high modulus, etc. Its enhancement and flame retardant modification can significantly improve its heat resistance, modulus dimensional stability, and flame retardancy. Used in industries such as automobiles, electrical and electronic, and power tools. The modified PA series materials include laser engraving, flame retardant, abrasion resistance, antistatic, carbon fiber modification, injection molding grade magnetic permeability, wading products, automobile use, etc.
Plastic modification is used, so what is plastic modification?
Plastic modification is the use of general resins through physical, chemical, and mechanical methods to improve or increase their functions, and use them under special environmental conditions in terms of electricity, magnetism, light, heat, aging resistance, flame retardancy, and mechanical properties. Function.
When it comes to plastic modification, many people think of filling, blending, fiber reinforcement, etc., but few people have a comprehensive understanding of plastic modification technology and methods. In fact, the commonly used methods of plastic modification are as follows:
1. Add modification
(1) Add small-molecule inorganic or organic matter
A modification method in which small-molecule inorganic or organic substances are added to the polymer (resin) to obtain a certain expected performance through physical or chemical action. This method is the earliest modification method. Its modification effect is obvious, the process is simple, and the cost is low, so it is widely used. It is believed that all those who have done graduation projects in colleges and universities will come into contact with and understand this method.
(2) Adding polymer substances
This method is also known as blending modification, and its main method is to mix one or more other resins (including plastics and rubber) into a resin to change the original resin properties. Since the blended and modified composite systems are all high-molecular substances, their compatibility is better than the system with small molecules added, and the modification does not have much impact on the other properties of the original resin at the same time. The common polymer alloys are the modified products of this method. Blending modification is the most effective way to develop new polymer materials, and it is also the main way to achieve high performance and refinement of existing plastic varieties.
Reducing the cost of plastics has always been the pursuit of manufacturers, so some modification methods will be used to reduce costs. The main methods include adding fillers and blending cheap resins. Of course, it is hoped that suppliers can reduce costs while not forgetting the need for performance.
