In addition, when the plastic bucket is exposed to light, there will be temperature changes, which can be regarded as heating. The increase of temperature will accelerate the dispersion of oxygen, and then increase its oxidation rate, which will lead to thermal bonding and cracking. In addition, touching the oxygen in the air and even ozone, over fire bonding or molecular chain cracking can accelerate aging, and there are other elements such as water, high-energy radiation The media, etc. Therefore, try not to expose to the sun when using plastic buckets daily. These are the reasons why plastic drums are easy to age summarized by the manufacturer of plastic drums. Plastic buckets can be seen almost everywhere in life. Although their price is not expensive, people should also pay attention when using them. Plastic is a kind of aging material, especially under ultraviolet radiation, its aging speed will be greatly accelerated. Therefore, plastic buckets need to be carefully stored to avoid long-term storage under high temperature, direct sunlight and other environments.

The grain size of the plastic in the plastic bucket is very harmful. The relativity of optical rotation is small or no optical rotation. The surface energy of the plastic bucket is low, which will harm the adhesion of all coatings. Because plastics are not conductive conductors and insulators in China, we cannot immediately carry out different coating on the surface of plastic barrels according to a set of electroplating process technical processing process design standards. Therefore, before the problem of information resource management on the surface of plastic barrels, it should be solved before social development, In order to better improve the bonding property of commercial coating and provide a conductive layer with excellent bonding property in coating solution. The front solution includes plastic product surface degreasing, vegetable oil cleaning, film remover, and active plastic product surface to improve coating adhesion. (1) Degrease the plastic bucket. Degreasing similar to metal manufacturing, and degreasing of plastic products can be cleaned with solvent or partial alkaline solution containing surface surfactant. Solvent degreasing is suitable for cleaning paraffin, liquid paraffin, body fat and other organic chemical stains on the surface. Commonly used solvents can not dissolve, solubilize or crack plastic products, with low melting point, easy volatilization, no toxicity, and nonflammable. Meta alkali solution is suitable for degreasing of alkali resistant plastic products. Because there are anhydrous aluminum chloride, meta alkali salt and chemical substances that carry out specific scientific research on different surfaces in this kind of standard solution. The common surface specific compounds are OP series products, namely alkyl carboxylic acid polyoxyethylene ether, which is not easy to develop into a foam plastic and does not remain on the surface of plastic products. (2) The activity of the surface of the plastic bucket. Some plastic barrels, such as polyethylene goods and ABS goods, can also be immediately coated on the surface of plastic barrels without organic chemical air oxidation. In order to better obtain high-quality coating coverage, air oxidation solution after degreasing can also be carried out for ABS products. Thin chromic acid solution diluent can be used. The typical solution secret is 420 g/L chromic acid and 200 ml/L hydrochloric acid (1.83%). The typical treatment is 65 ℃/five minutes and ten minutes, cleaning and drying. The advantages of chromic acid etching processing: the symmetrical solution of various and complicated plastic products; Defects of chromic acid etching process: actual operation risk.

What causes the temperature to be too high when processing plastic buckets? The reason for the high temperature during the processing of the plastic bucket: the volume of the plastic bucket oil tank is too small, the heat dissipation area is not enough, and the cooling device is too small. The high temperature of climate and operating environment causes the oil temperature to rise. The viscosity of the selected oil is not appropriate, the viscosity is large, the viscosity resistance is large, and the leakage will increase if the viscosity is too small, both of which can cause heating temperature rise. The pipeline of the plastic bucket system is too thin and too long, too much bending, and large local pressure loss and pressure loss along the way. The precision of components is not enough and the assembly quality is poor, and the mechanical friction loss between relative motions is large. The fit clearance of the mating parts is too small, or the clearance is too large after use, resulting in large internal and external leakage, resulting in large volume loss. For example, the volume efficiency of the pump is reduced, and the temperature rises quickly. The constant displacement pump oil supply system of the plastic bucket with the oil pump capacity selected according to the fast forward speed will have most of the excess flow flowing back from the overflow valve and generate heat when working. The unloading circuit in the system fails or the oil pump cannot unload when it stops working because no unloading circuit is set. All the flow of the pump overflows at the bottom, causing overflow loss and heating, resulting in temperature rise.

When it comes to plastic packaging barrels, we are no strangers. Most of its materials are made of polyethylene, polypropylene and other plastics by blow molding and injection molding. They are used for the external packaging of liquid and solid objects in chemical, pesticide, medicine, food, hardware, electronics, electromechanical and other industries, and play an important role in our daily transportation. Now let's introduce the functions and characteristics of plastic packaging barrels. First of all, it has beautiful appearance, smooth inside and outside, seamless without welding, light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and convenient transportation. It has a long service life and can be used for at least one and a half years under normal filling, transportation and loading and unloading conditions. Its product technical parameters are strictly in accordance with national standards, and the appearance design and size of the product can also be customized according to needs. The temperature that can be used for hot filling shall not exceed 60 ℃ generally. After hot filling, the lid and stacking shall be closed after the contents are fully cooled and cooled to room temperature. If the easily dispersed chemicals are contained, the cover with exhaust function can be used to avoid the danger of overpressure during transportation and ensure the sealing performance of the liquid.
