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.

The main features of the chemical plastic bucket are as follows: the product color is bright and round: the imported food grade color masterbatch is used to make the product dyed evenly and the appearance more bright and round; 2. The wall thickness of the whole barrel is uniform and symmetrical: 360 points of wall thickness control skills make the wall thickness of each barrel very uniform; 3. The appearance of the product is clean and smooth: people rely on clothes and horses rely on saddles - each one has a specialist to recheck to ensure that there are no black spots, strains, ribbons, deformation, etc. on the surface of the barrel, so as to improve the beauty; 4. Humanized planning of the whole barrel: each barrel shape fully considers the humanization at the beginning of the planning, making the products more comfortable to carry and more convenient to pour; 5. Diversified sealing methods: aluminum foil induction seal, inner plug seal, chemical foaming seal ring seal, WAKE silicone seal, EPE seal; 6. Excellent chemical stability and anti drop test: ensure the safety of product transportation, especially the transportation of hazardous chemicals; 7. High beauty of the can body: high cost performance and strict control of concave convex deformation, which conforms to the beauty of international review; 8. The first article test of the batch includes: high temperature stacking test, hydraulic leakage test, air tightness test and drop test.

The common cooling shaping plastic barrel is the later stage of the injection molding process, starting from the freezing of the gate and ending with the demoulding of the product. At this stage, feeding or backflow will not continue, and the plastics in the cavity will continue to cool, harden and shape. When demoulding, the plastic parts have enough rigidity to prevent warping and deformation. The plastic bucket produced by this method has many advantages as well as some disadvantages. If the plastic bucket manufacturer will encounter a series of flow resistance in the injection process, part of the resistance comes from the external friction of the barrel, nozzle, mold gating system and mold cavity surface wall against the melt, and the other part comes from the viscous internal friction generated inside the melt itself. In order to overcome the flow resistance, the injection machine must apply a large injection pressure to the melt through the screw or plunger. This is not a big problem, as long as you pay attention to this problem can also be avoided!

The wholesale of plastic drums with polar groups will make the materials hygroscopic. If stabilizers, plasticizers, fillers and other additives in plastics contain hydrophilic groups, polar groups, etc., they will also increase the rate of moisture absorption of materials. The rate of moisture absorption of plastics from the air is also related to the specific surface of materials. The feeding state of plastic materials is mostly granular (thermoplastic) (thermosetting plastic molding powder, some thermoplastic resin powder), with large specific surface area and fast moisture absorption rate from the air. Long term stored plastic is easy to achieve moisture absorption balance and contains more water. Before molding, it must be fully dried, otherwise there will be surface silver filaments, internal bubbles and other defects during the molding of products, and some plastics will be hydrolyzed and degraded, which will cause the hygroscopicity of plastic products under mechanical properties to affect the performance of products, Inhalation of moisture inside the products often acts as a plasticizer, which significantly reduces the wholesale of plastic barrels, changes the mechanical properties, and the plastic with obvious moisture absorption also has an impact on the size of plastic parts.
