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.

Briefly describe the repair method of the damaged packaging barrel: first remove the external dirt on the damaged part of the packaging barrel, first wipe off the dirt with a rag, and then scrape out new debris with a knife. If there is any oil stain, first use hot alkaline water to remove the oil, then wash the alkaline solution with clean water, and then use a knife to scrape the surface. When patching cracks, it is necessary to cut a plastic sheet of the same type that is slightly longer and wider than the crack, and has no aging, and treat the appearance. Then, at the place where the packaging barrel is broken, all of them are glued in order, and wet cloth is used to press them to make the bonding more tight. The packaging barrel is beautiful in appearance, smooth in appearance, seamless in appearance, light in weight, good in strength, impact resistant, non-toxic and tasteless, convenient in transportation, and has a long service life. Under the conditions of normal filling, transportation, loading and unloading, the warranty period is 1.5 years. The technical parameters of the product should strictly comply with the standards, and the product appearance design and product dimensions can also be customized according to the needs. Hot filling can be used, and the general temperature should not exceed 60 ℃. The lid and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature. Chemical packaging barrels are mostly made of plastic, commonly known as plastic chemical barrels or plastic chemical barrels. They are developed and blown with scientific formulas. They are beautiful and generous in appearance, prevent leakage, and will not deform. They are ideal for long-distance transportation of packaging materials for chemical products. The chemical packaging barrel has good anti-corrosion performance, and a variety of raw material "O" type sealing rings are selected to meet different filling requirements. The residual amount after dumping is small, and it can be used more than 20 times under normal filling, transportation and loading and unloading conditions. It not only saves energy but also reduces the cost of use.

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.

The plastic bucket will leak after a long time of use. If we find a small hole after inspection, we can use adhesive to repair it. If the hole is relatively large, this method is not feasible. At this time, we can find some special tools for plastic welding to repair. Or use some suitable plastic buckets to weld to the leaking place. The above methods are aimed at the non serious water leakage phenomenon, so these methods are relatively simple and not applicable to those with serious water leakage. If it is a very serious water leakage, even if the welding method is used, it will work for a while, but it will still leak after a period of use. In this case, we recommend that you use a new plastic bucket to avoid serious water leakage. In addition, to prevent people from using plastic buckets, In the process of use, everyone should pay attention to the maintenance of the plastic bucket. Do not break it in use, which will shorten the service life of the plastic bucket.

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.
