Briefly describe the repair method of the damaged packaging barrel: first remove the external dirt on the damaged part of the packaging barrel, first wipe off the dirt with a rag, and then scrape out new debris with a knife. If there is any oil stain, first use hot alkaline water to remove the oil, then wash the alkaline solution with clean water, and then use a knife to scrape the surface. When patching cracks, it is necessary to cut a plastic sheet of the same type that is slightly longer and wider than the crack, and has no aging, and treat the appearance. Then, at the place where the packaging barrel is broken, all of them are glued in order, and wet cloth is used to press them to make the bonding more tight. The packaging barrel is beautiful in appearance, smooth in appearance, seamless in appearance, light in weight, good in strength, impact resistant, non-toxic and tasteless, convenient in transportation, and has a long service life. Under the conditions of normal filling, transportation, loading and unloading, the warranty period is 1.5 years. The technical parameters of the product should strictly comply with the standards, and the product appearance design and product dimensions can also be customized according to the needs. Hot filling can be used, and the general temperature should not exceed 60 ℃. The lid and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature. Chemical packaging barrels are mostly made of plastic, commonly known as plastic chemical barrels or plastic chemical barrels. They are developed and blown with scientific formulas. They are beautiful and generous in appearance, prevent leakage, and will not deform. They are ideal for long-distance transportation of packaging materials for chemical products. The chemical packaging barrel has good anti-corrosion performance, and a variety of raw material "O" type sealing rings are selected to meet different filling requirements. The residual amount after dumping is small, and it can be used more than 20 times under normal filling, transportation and loading and unloading conditions. It not only saves energy but also reduces the cost of use.

For chemical drums, it is very important to master the temperature. Because temperature has a significant impact on the function of plastic extrusion and parison, improving the extruder temperature can reduce the viscosity of the melt, improve the fluidity of the melt, and improve the screw speed without affecting the mixing and plasticization of plastic. To achieve this goal, we can use electronic temperature controller to make the process temperature stable and save energy significantly. It must be well understood that humidity will affect the drying rate of chemical drums. When the relative humidity in the bucket is low, the pressure difference between the surface and the water vapor in the dryer is large, and the drying speed is fast. The isolation function of chemical drums from oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times, and the basic characteristics of plastic containers should be grasped. Therefore, when selecting plastic containers, it is necessary to fully understand that plastic related functional chemical barrels are generally made by molding. Different molding methods often have a great impact on the function and cost of products.

The analysis and inspection of the quality of the molding raw materials shall be based on the requirements of the process characteristics of the injection molding raw materials. The water content, fineness, impurities, uniformity, color and luster of the raw materials shall be inspected, and the fluidity, thermal stability, shrinkage and other indicators shall be tested. If problems occur in the inspection, measures shall be taken in time to solve them. Preheating and drying: For plastics with strong moisture absorption, such as polycarbonate, ABS, nylon, etc., before molding, according to the moisture content requirements allowed by the molding process, fully preheat and dry them to remove excessive volatile matter and moisture in the materials, so as to prevent bubbles and silver filaments in the molded plastic parts, and also to avoid water degradation during injection. In injection molding production, in order to make the plastic parts easier to come out of the mold, some also need to coat a layer of release agent on the mold cavity or mold core. The commonly used release agents are silicone oil, zinc stearate, liquid paraffin, etc. For soft products or transparent products containing rubber, it is not recommended to use release agent for demoulding, otherwise the transparency of the products will be affected. In production, if it is necessary to change the type of plastic, change the color, change the material, or find that thermal decomposition or degradation reaction occurs in the molding process, the barrel of the injection machine should be cleaned. The barrel of plunger injection machine must be disassembled for cleaning. The spiral charging drum can be cleaned by air injection method. When the air injection method is used to clean the spiral carbon cylinder, if the molding temperature of the plastic to be replaced is lower than the molding temperature of the residue in the cylinder, first raise the temperature of the cylinder and nozzle to the molding temperature of the plastic to be replaced, cut off the power supply and add the return material of the plastic to be replaced, and then continue air injection to remove all the residue. Usually, after the plastic buckets are filled, they are stacked to reduce the storage space, which requires that the plastic buckets can also bear a certain weight.

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.
