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.

At present, there are many kinds of packaging products on the market, among which plastic packaging barrels are more common. With more and more types of plastic packaging barrels, the market pressure also increases, and the brands and product characteristics of various manufacturers are also diverse. Now let's talk about the performance of plastic packaging barrels. 1. Corrosion resistance: the plastic bucket with corrosion resistance shall not have any crack, blister or deformation after being immersed for 48 hours in the corrosive chemicals with temperature maintained at 75 ℃. 2. Aging resistance: ⑴ Material aging resistance: aging time (h) Impact strength change rate after artificial aging 6000 ≤ 40% ⑵ Inject high-quality UV resistant raw materials, color pigment 5%, and ensure 8 years (outdoor) without fading. 3. Hardness index: ≥ 65. 4. Cold and heat resistance: working temperature: - 30 ℃~50 ℃. Destructive test: - 30 ℃~110 ℃ (softening temperature). Detailed description: The plastic bucket will be refrigerated at - 18 ℃ for 12 hours at first, and then a 65mm diameter and 5kg weight iron pillar will be used to drive down from 1m height to the injection point of the plastic trash can for three consecutive times. After the low temperature test, the plastic bucket body should not be cracked or deformed. 5. High temperature resistance: put the plastic bucket into a room with a temperature of 90-95 ℃ for 3 days. After cooling, the surface of the plastic bucket shall not be damaged, blistered or deformed. The moisture absorption of raw materials is less than 0.01 to ensure that the box structure will not become brittle and deformed. 6. Lifting and dumping: place in the calibration environment for more than 12h, add 120kg load, and continuously lift, dump, and drop for more than 2000 times without cracks. In addition, the static test shall be carried out on the empty and loaded plastic drums on the inclined surface with an inclination angle of 100, and the plastic drums shall not be dumped. 7. UV protection and hardness test: from the perspective of engineering plastics, the UV protection components in raw materials are closely related to the hardness of plastic drums. In addition, the intensity of ultraviolet light in every corner of the world is different. And in the same place, different colors have different reactions to ultraviolet rays. 8. Barrel wall thickness: from the perspective of engineering plastics, the barrel wall thickness is not the main reason for determining the toughness of the barrel. The raw materials used, UV protection ingredients, molds and injection molding equipment are all related. For most customers, the quality of the plastic bucket does not depend on the wall thickness but whether the plastic bucket can pass different test conditions. The wall thickness depends on the design of each mold.

For the newly bought plastic bucket, put two pieces of fresh lemon into the cup, put the quilt in the bucket, and then cover it for a few hours; Wipe the inner wall of the plastic bucket with soaked tea, and wash it with clean water to remove the peculiar smell in the bucket; In addition, use a few milliliters of salt dipped in water to scrub inside the bucket to remove odor. Through the above tips, you can effectively remove the odor of newly bought plastic barrels. As an enterprise specializing in the production of various plastic barrels, we are very cautious in the selection of raw materials, in order to reduce the impact of the odor of plastic barrels on purchasing judgment. If there is anything that consumers do not understand about the removal of odor from plastic barrels, they can contact us, and we are happy to serve you.

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!
