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.

When wholesaling plastic buckets, you must pay attention to the choice of plastic materials! The wholesale orientation of plastic drums can only be carried out in the viscous flow state. Both chain segment orientation and whole chain orientation are thermodynamic non-equilibrium states. When the external force is released, the chain will be in a random state again due to the thermal movement of molecules, which is called solution retrieval. Only when the chain segment or molecular chain after removal is rapidly cooled to the glass transition temperature can the removal space be retained. This "frozen" orientation is only relatively stable, and it will also be slowly de oriented. As the material temperature increases, the recovery will rapidly advance ˉ The orientation of molecular chains will be produced in the melting process of plastics, such as injection and extrusion. The effect of orientation on the product is the anisotropy of properties. The strength and modulus in the orientation direction increase significantly, and the strength and modulus perpendicular to the orientation direction decrease significantly. This is because the atoms of the molecular chain in the orientation direction are bound by chemical bonds, while the force between the molecular chains perpendicular to the orientation direction is the van der Waals force.

We can also use soap to add a small amount of ammonia water mixture for removal, which can also make the shell of the chemical plastic bucket more shiny. You can also use the heating method to soften the residues on the plastic bucket with the hot air of the hair dryer, and the residues can be easily removed when the viscosity of the residues becomes smaller. Of course, we can also use a very familiar eraser for erasing, but the viscosity of the residue is different, so the erasing time is also different. If there is alcohol, it can be used together with alcohol to make the erasing effect better. There are many ways to decontaminate plastic packaging barrels, not only the above, but also the essential balm we often use has a certain decontamination effect. You can refer to the above content when decontaminating.

When the surface of the plastic bucket is labeled, the labeling surface should be flat. A "frame" can be designed on the surface of the plastic bottle, so that the label can be positioned accurately without movement. During blow molding, the first contact part of parison inflation always tends to be the first hardened part. Therefore, the wall thickness of this part is also larger. The edge and corner are the parts where parison inflation contacts, and the wall thickness of this part is small. Therefore, the edges and corners of plastic bottles should be designed as rounded corners. The rigidity and bending resistance of plastic bottles can be improved by changing the surface shape of the plastic bottle, such as making the middle of the plastic bottle relatively thin, and increasing the circumferential grooves or ribs on the surface of the plastic bottle. The longitudinal grooves or stiffeners can eliminate the deviation, sagging or deformation of plastic bottles under long-term load. The printing surface of the plastic bucket is where consumers focus their attention. The printing surface shall be flat and continuous; If the plastic bottle contains a handle, a groove, a reinforcing rib and other structures, attention should be paid not to inconvenience the printing operation during the design. The elliptical plastic bottle has high rigidity, but the manufacturing cost of the mold is high. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to selecting materials with high rigidity, it is also necessary to enhance the rigidity and load resistance strength of the plastic bottle through the shape design of the plastic bottle.

Three points are summarized for you, hoping to help you choose high-quality plastic chemical barrels. 1. Look at the material: the material of plastic determines the basic characteristics of plastic containers. Plastic packaging containers with the same or similar shapes may have extremely large differences in use performance due to different materials. The price of plastic barrels is different for different materials. 2. Look at the model: different specifications of plastic barrels have different capacities and bear different pressures, depending on the needs of your own products. 3. Look at the thickness: the thickness is very important under the same capacity, which is mainly determined by the materials in place.
