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.

With the use rate of 200L large plastic barrels getting higher and higher, more and more old plastic barrels begin to appear gradually, including some plastic barrels that are broken during transportation, so we specially talk about how to repair the cracks on the plastic barrels. Now 200L plastic drums basically contract the transportation of chemical products, and the cost of plastic ton drums is also very high. If the old and damaged ton drums are replaced with new ones, the cost is too high. So let's talk about the repair of plastic buckets. Plastic buckets are indeed carriers for transporting chemical products, even dangerous plastic buckets, but they are not irreparable. The glue specially used to repair the plastic bucket is AB glue, which is composed of two kinds of glue liquids, one is hardener and the other is the glue. The combination of two liquids can achieve good bonding effect of zui, and the temperature must be appropriate. Although the use conditions are harsh, the bonding effect of the plastic bucket is extremely good. The 200L plastic bucket we usually use is always transported on the truck, and damage is inevitable during long-distance transportation. So many enterprises using plastic ton buckets will prepare sufficient AB glue.

Bubbles sometimes appear in the production of plastic barrels. What will the production personnel do? Let the plastic bucket wholesale to answer for you. After the plastic bucket is filled with liquid, screw the vent cap, lie on the side for 1 minute, make the permeable film soak the liquid, and then store the plastic bucket vertically for 3-7 days or longer. The specific test time needs to be determined by oneself, and the temperature should follow the temperature under the practical application state (the bucket is placed in the oven after the liquid is filled). The storage temperature of the plastic bucket is generally 40-50 ℃. When the expected time is up, check whether the bucket expands. If there is slight swelling, the demander will decide whether to use it; If there is serious bulge, it is determined that this ventilation cover is not applicable.

The method to distinguish the quality of plastic drums: whether there is a relevant production license, such as the national license for dangerous goods packaging products. For the raw materials selected for the plastic bucket, brand new materials are preferred; Look at various performance indicators of the product. Such as mechanical strength, heat resistance, and solvent resistance. Now, many enterprises will first consider the price and then the quality when choosing plastic buckets. This seems reasonable, because the profit and cost are placed there. Everyone is willing that the lower the cost, the better, and the higher the profit, the better. Many large and powerful enterprises will have their own proprietary departments to analyze the possible profit and loss risks of their products, which must include costs and profits. Now plastic buckets are indispensable in all major industries, because they can store goods more efficiently. However, the barrier performance of different quality plastic buckets to oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times. Therefore, when selecting plastic buckets, we must pay attention to that the quality of plastic buckets cannot be judged only by their appearance, but the basic characteristics of plastic containers. When selecting plastic containers, be sure to fully understand the relevant properties of plastic. Plastic barrels are generally made by molding. Different molding methods often have a great impact on the performance and cost of products.

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 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.
