As a storage container, plastic packaging barrels are very popular. But even good quality plastic buckets may be deformed. How can we prevent this? Here are some prevention methods. First of all, we should cherish the use of plastic buckets when using them, and handle them gently when transferring, loading and unloading plastic buckets and in daily use. Secondly, during storage and transportation, the ground should be flat to prevent the plastic bucket from being tilted, and more importantly, to avoid collision between the bucket and sharp objects. When filling and sealing the lid, try to use a rubber hammer less than one pound to press the opening of the tear belt first, and then knock the lid down evenly along the outer circumference of the top of the lid. The knocking force should be less than 8KG. The contact between the rubber hammer and the lid should be parallel and not be tilted. Otherwise, it is easy to break the lid. The plastic bucket mouth shall be placed upward during storage. The containers shall be stacked tightly and firmly or have enough support and reinforcement. A layer of thin plate shall be laid on every two layers of plastic drums before stacking to avoid unnecessary losses caused by excessive stress on the drums due to fluctuations and bumps during transportation. Of course, the above preventive measures play a certain role in preventing the deformation of plastic packaging barrels, but their daily use is also important. On the other hand, it is also related to the quality of packaging barrels. Choosing a high-quality plastic barrel manufacturer has greater benefits for later use

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.

Bubbles sometimes appear in the production of plastic barrels. What will the production personnel do? Let the plastic bucket wholesale to answer for you. After the plastic bucket is filled with liquid, screw the vent cap, lie on the side for 1 minute, make the permeable film soak the liquid, and then store the plastic bucket vertically for 3-7 days or longer. The specific test time needs to be determined by oneself, and the temperature should follow the temperature under the practical application state (the bucket is placed in the oven after the liquid is filled). The storage temperature of the plastic bucket is generally 40-50 ℃. When the expected time is up, check whether the bucket expands. If there is slight swelling, the demander will decide whether to use it; If there is serious bulge, it is determined that this ventilation cover is not applicable.

There are several ways to remove the residue on the plastic packaging bucket: because the plastic packaging bucket is made of PE, after using the plastic bucket, there will be a lot of oil stains on the inner wall of the bucket, and it is also very difficult and troublesome to clean. Now, Shandong Zhongcheng Packaging Co., Ltd. will introduce the method to remove the residue of plastic chemical barrels. When we remove the residue on the chemical barrel, whether using polishing water or vinegar, we should ensure that it is soaked for a long time, so as to ensure that the residue in the barrel can be removed. Find a piece of dry cloth dipped with vinegar to cover it on the chemical plastic bucket with residue. After the impurities on the bucket are soaked, use a hard small slice to easily remove the residue of trade.
