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.

In addition, when the plastic bucket is exposed to light, there will be temperature changes, which can be regarded as heating. The increase of temperature will accelerate the dispersion of oxygen, and then increase its oxidation rate, which will lead to thermal bonding and cracking. In addition, touching the oxygen in the air and even ozone, over fire bonding or molecular chain cracking can accelerate aging, and there are other elements such as water, high-energy radiation The media, etc. Therefore, try not to expose to the sun when using plastic buckets daily. These are the reasons why plastic drums are easy to age summarized by the manufacturer of plastic drums. Plastic buckets can be seen almost everywhere in life. Although their price is not expensive, people should also pay attention when using them. Plastic is a kind of aging material, especially under ultraviolet radiation, its aging speed will be greatly accelerated. Therefore, plastic buckets need to be carefully stored to avoid long-term storage under high temperature, direct sunlight and other environments.

The volume of the plastic bucket oil tank is too small, the heat dissipation area is not enough, and the cooling device has too small capacity. The high temperature of climate and operating environment causes the oil temperature to rise. The viscosity of the selected oil is not appropriate, the viscosity is large, the viscosity resistance is large, and the leakage will increase if the viscosity is too small, both of which can cause heating temperature rise. The pipeline of the plastic bucket system is too thin and too long, too much bending, and large local pressure loss and pressure loss along the way. The precision of components is not enough and the assembly quality is poor, and the mechanical friction loss between relative motions is large. The fit clearance of the mating parts is too small, or the clearance is too large after use, resulting in large internal and external leakage, resulting in large volume loss. For example, the volume efficiency of the pump is reduced, and the temperature rises quickly. The constant displacement pump oil supply system of the plastic bucket with the oil pump capacity selected according to the fast forward speed will have most of the excess flow overflowing from the overflow valve under high pressure and generate heat during operation. The unloading circuit in the system fails or the oil pump cannot unload when it stops working because no unloading circuit is set. All flow of the pump overflows under high pressure, causing overflow loss and heating, resulting in temperature rise.

Although plastic buckets can be seen everywhere, do you know how they are packaged? What technology is there for packaging? 1. Plastic packaging barrel packaging: Fieldbus technology. The use of fieldbus technology has mainly "liberated" most of the hardware, simplifying the cumbersome device links; In the practical process of production and use, convenience and flexibility become more and more obvious; It can integrate fieldbus skills with the ERP system, so that the management can easily access and analyze operating data through the ERP system, understand the production practice and immediate situation, and monitor the operation of the workshop. Fieldbus technology is widely used in large food processing enterprises in China, which facilitates the unmanned operation of the entire production line and the seamless connection of transmission, detection and other processes. 2. Sensor plastic packaging barrel packaging technology. In the food processing and packaging machinery profession, the use of sensors is complex, and sensors are used in the monitoring of food and beverage storage tanks, filling and packaging, mixing and processing, cooling and heating, cleaning, packaging and other processes. The gap in the market for the use of this skill has become a must for many automation manufacturers. 3. Drive operated packaging barrel packaging technology. The use of transmission products in packaging machinery is mainly to adjust the main process speed and control the periodic change of motor speed in the production process. But for most packaging machinery, frequency converter is not a necessary electrical product. The application rate of frequency converter in this profession is low, and there is a large space for development in large standard machines and packaging production lines.

Plastic barrel modification equipment What are the processing equipment for plastics? Plastic barrel modification equipment Plastic modification involves four aspects: raw and auxiliary materials used, processing equipment, modification technology and effect, and specific application. According to the plastic modification process, the processing equipment can generally be divided into four categories: primary mixing, melt mixing, pelletizing and drying. The corresponding equipment is introduced as follows: primary mixing equipment. Primary mixing equipment refers to the equipment used for mixing materials in the non melting state. The equipment used for primary mixing is almost intermittent. There are many types of primary mixing equipment, such as rotary drum mixer, double cone mixer, spiral belt mixer, Z-shaped kneader high-speed mixer, etc., but at present, the two types of widely used plastic mixing processes are Z-shaped kneader and high-speed mixer. Z-shaped kneader Z-shaped kneader, also called double arm kneader, is mainly composed of rotor, mixing chamber and driving device. The rotor is installed in the mixing chamber. The mixing chamber is a steel trough with a W-shaped or saddle shaped bottom. The upper part is provided with a cover and a feeding port, and the lower part is generally provided with a discharge port. The steel trough is jacket type, and heating and cooling medium can be fed into it. Some high-precision mixing chambers are also equipped with vacuum devices, which can discharge moisture and volatile matter during the mixing process. There are two types of rotor installation in the mixing chamber, one is tangential installation and the other is intersecting installation. In tangential installation, the movement traces of the outer edges of the two rotors are tangent; In the intersecting installation, the movement traces of the outer edges of the two rotors are intersecting. During tangential installation, the rotor can rotate in the same direction or in different directions, and the speed ratio between rotors is 1.5:1, 2:1 or 3:1. The rotor installed in intersecting mode can only rotate at the same speed because the outer edge movement traces intersect. The clearance between the outer edge of the rotor installed in an intersecting way and the wall of the mixing chamber is very small, generally about 1mm. In such a small gap, materials will be strongly sheared and squeezed. This effect can be physically modified by filling and blending.
