Next, the plastic bucket manufacturer will tell you how to prolong its service life as much as possible. As a widely used container, plastic bucket has been recognized by more people, and its use is very convenient. However, attention should be paid to how to extend its service life. Pay more attention during the storage of plastic buckets, so that they can be used longer. The chemical reaction of plastic bucket exposed to the sun is caused by many factors. First, ultraviolet radiation, the leading element of photochemical reaction, can directly cause the cracking of molecular chains. In all the light, the shorter the wavelength and the greater the energy, the faster the aging of the plastic bucket. Because rubber and plastic materials will produce free groups when absorbing light energy, and then cause and accelerate some adverse chain reactions.

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 it in the calibration environment for more than 12h, add a 120kg load, and continuously lift, dump, and drop it 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.

The advantages of chemical barrel! Chemical barrel is mainly composed of extrusion and blow molding, so it is generally called blow molding in the industry. The products produced by this process are made of plastic particles that pass through the hopper mouth, melt them through the heating of the cylinder in the three-stage heating zone, form them through the filter screen, clamp the parison into the petal closing mold to be blown when it is hot, blow it with compressed air, reach the mold cavity body, and open the petal closing mold after cooling and shaping under the condition of maintaining a certain time and air pressure, Then you can see the chemical barrel products. The volume of the oil tank of the chemical drum is too small, the heat dissipation area is not enough, and the capacity of the cooling device is too small. The high temperature of the climate and operating environment causes the rise of the oil temperature. The viscosity of the selected oil is improper. The viscosity is large, and the resistance of viscosity is large. If the viscosity is too small, the leakage will increase. Both conditions can generate heat and temperature rise

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.

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.
