The orientation will also cause the difference of shrinkage and refractive index between the two directions of the product. In the production process of injection products, orientation is often used to improve the mechanical properties of the product in a certain direction. The orientation will also have an adverse effect on the product, making the product change its size, produce deformation or even crack in the direction perpendicular to the orientation due to the process of de orientation in the working process). In view of this situation, necessary treatment such as heat treatment should be carried out in advance after the molding of the work in progress, to create the necessary conditions for the reorientation of the oriented molecules, and to avoid the "freezing" of the molecular chain orientation in the work in progress, which brings about the above drawbacks during the injection, extrusion and other molding processes, the material molecular chain only produces uniaxial orientation. Uniaxial orientation has been fully applied in the production of plastic single fiber and film, which is used to improve the strength of single dimensional length direction and the strength of film in a certain direction. Biaxial orientation can improve the strength in all directions of the film plane, and also can improve the strength of the plexiglass plate. 5) Hygroscopicity Hygroscopicity refers to the tendency of plastic materials to absorb water from the air. Some plastics, such as polyamide and phenolic plastics, have an obvious moisture absorption tendency due to the hydrophilic group of resin molecular chain 1.

What factors will affect the performance of the plastic bucket? At present, plastic buckets are common to us, and everyone will use them. The performance of plastic bucket is very advantageous. You can choose different plastic buckets according to different liquids. The production process of the seemingly simple plastic bucket is not so simple. When producing plastic buckets, the manufacturers of plastic buckets still need to pay attention to some small problems that will affect the performance of the finished plastic buckets, which will greatly reduce the sales rate of plastic buckets. 1. The blowing speed determines the performance of plastic bucket products. 2. The cold temperature time determines the performance of plastic bucket products. 3. The expansion rate determines the performance of plastic bucket products. 4. Uneven longitudinal wall thickness of plastic bucket products determines the performance of products. 5. The performance of plastic bucket products is determined by the uneven horizontal wall thickness. 6. Plasticizing temperature and time determine the performance of plastic bucket products.

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.

How to deal with the liquid container after use? The used liquid packaging barrels are not allowed to be thrown randomly, and must be disposed properly, otherwise it will cause environmental pollution. Pay attention to the following points when handling: 1. First, ensure that the vehicles transporting liquid packaging barrels are in good condition. 2. Construction waste: waste oil drums, waste paint drums, waste fire extinguisher cans, waste plastic cloth, waste chemical materials and their packaging materials, waste glass fiber cloth, etc., shall be disposed according to relevant regulations, and shall not be discharged at will, otherwise serious harm will be caused. 3. Try to recycle the waste and do not cause secondary pollution. According to the requirements of relevant national laws and regulations, the waste paint bucket in the liquid packaging bucket belongs to hazardous waste. Recycling can only be done by a qualified waste disposal company. However, there are a large number of waste paint buckets, each of which is 1.5kg-2k. If hazardous waste is treated, a lot of treatment costs will be incurred.

Use characteristics of plastic barrels: plastic packaging barrels are mostly used for the packaging of liquid and solid products. They have good performance and quality. They are not easy to rust and break, light in weight, and have excellent oil resistance and strong corrosion resistance. It is mainly used for packaging dangerous goods that need moisture-proof, waterproof, heat insulation, pressure resistance and corrosion resistance. Its material is plastic, such as polyethylene, polyester, etc., which is made by blow molding, injection molding, blistering and roll molding. It is mostly used to contain liquid and solid articles in chemical, pesticide, medicine, food and other industries. The specifications range from 1L-25L open and closed plastic barrels, which can be used for goods storage, transportation and turnover. It will not dissolve harmful substances. PP polypropylene, PC polycarbonate and block copolymer are harmless in themselves, and their melting point is more than two hundred degrees. They will not decompose when boiled. However, many additives will be added in the molding process. In order to enhance toughening, anti-aging and anti-oxidation, they are not toxic in themselves, and the content of food grade additives is strictly required, It is also easy to volatilize. Because the tank is engraved with a capacity height, the filling height can be clearly seen through the transparent tank when filling materials in ton barrels, and the filling amount can be accurately controlled. The tank is made of first-line authentic high-density polyethylene raw materials, and the strength and toughness of the products are purchased.
