Main properties and characteristics of plastic barrels ① A few plastic packaging barrels have poor high temperature resistance and become brittle under high temperature; ② Good resistance to attack and attack, will not produce serious repercussions; ③ It has good general formability and colourability, and low processing cost; ④ Good insulation and low thermal conductivity; ⑤ Good transparency and wear resistance; ⑥ Most plastic packaging barrels have poor heat resistance, high shrinkage rate and are easy to extinguish; ⑦ Poor dimensional invariance and easy deformation; ⑧ Most of the plastic packaging barrels are light in weight, chemical properties remain unchanged, and will not breed serious reverberation and rust during operation; ⑨ Plastic packaging barrels are prone to aging, which will affect the operation efficiency and price in the long run; ⑩ Some plastic packaging barrels are easily soluble in solvents, and will melt when touching certain solvents.

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.

The forming time of the barrel has a great impact on the size of the mold! Plastic part structure The shape, size, wall thickness, presence or absence of inserts, the number and distribution of inserts have a great impact on the shrinkage. Generally speaking, plastic parts are complex in shape, small in size, thin in wall, with inserts, a large number of inserts and symmetrical distribution, and their shrinkage is small. The cooling and shaping process starts from the freezing of the gate to the demoulding of the product, which is a stage of the injection molding process. At this stage, feeding or backflow will not continue, and the plastics in the cavity will continue to cool, harden and shape. When demoulding, the plastic parts have enough rigidity to avoid warping and deformation. As the cooling process proceeds, the temperature continues to drop, and the plastic shrinkage pressure in the cavity drops to a lower value (but not necessarily equal to the outside atmospheric pressure) when the mold is opened.

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 not proper. The viscosity is large, and the resistance is large. If the viscosity is too small, the leakage will increase. Both conditions can generate heat and 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.
