With the use rate of 200L large plastic barrels getting higher and higher, more and more old plastic barrels begin to appear gradually, including some plastic barrels that are broken during transportation, so we specially talk about how to repair the cracks on the plastic barrels. Now 200L plastic drums basically contract the transportation of chemical products, and the cost of plastic ton drums is also very high. If the old and damaged ton drums are replaced with new ones, the cost is too high. So let's talk about the repair of plastic buckets. Plastic buckets are indeed carriers for transporting chemical products, even dangerous plastic buckets, but they are not irreparable. The glue specially used to repair the plastic bucket is AB glue, which is composed of two kinds of glue liquids, one is hardener and the other is the glue. The combination of two liquids can achieve good bonding effect of zui, and the temperature must be appropriate. Although the use conditions are harsh, the bonding effect of the plastic bucket is extremely good. The 200L plastic bucket we usually use is always transported on the truck, and damage is inevitable during long-distance transportation. So many enterprises using plastic ton buckets will prepare sufficient AB glue.

What causes the temperature to be too high when processing plastic buckets? The reason for the high temperature during the processing of the plastic bucket: the volume of the plastic bucket oil tank is too small, the heat dissipation area is not enough, and the cooling device is too small. 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 flowing back from the overflow valve and generate heat when working. The unloading circuit in the system fails or the oil pump cannot unload when it stops working because no unloading circuit is set. All the flow of the pump overflows at the bottom, causing overflow loss and heating, resulting in temperature rise.

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.

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.
