How to prevent the daily occurrence of static electricity in plastic buckets? Static electricity is always present, because we can't see it with the naked eye, so we don't know when the daily static electricity will occur. Any equipment will produce static electricity, even our daily sweaters! How can we prevent this phenomenon? Let's briefly introduce the relevant knowledge points. 1. Check whether the surface resistivity of the surface barrel is less than 1011 Ω to ensure that the surface charge dissipates in time. 2. The liquid metal tube is used for filling. Pay attention not to hang on the wall for filling, otherwise it will easily lead to brush discharge. 3. The metal pipe shall be grounded and the filling speed shall be within 1m/s. If the IBC electrostatic conductive tank is used, the metal pipe shall be bridged with the IBC metal frame and the metal frame shall be grounded. 4. For low conductivity liquid, because the surface area of the insertion tube contacting with the liquid is too small, the static charge in the liquid cannot be derived. It is not recommended to fill the low conductivity liquid. If it is necessary to use it, it can be considered to use it under the nitrogen seal condition. 5. Conclusion: Non antistatic can hold some flammable materials, but its volume is hindered. It is anti-static and can contain flammable liquid with high conductivity. Verify the anti-static capacity of the anti-static bucket.?

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

First, the outer cover needs to be tightened when installing (usually with the help of external force such as wrench). After the installation of the seal ring, it should be close to the contact plane of the barrel mouth to prevent the seal ring from distorting the installation. If the temperature of the filled product is higher than 40 ℃, the cap shall be screwed and stacked after the product is cooled. When stacking, pay attention to ensure the flatness. The upper base layer with large contact area shall be aligned, and the stacking shall not be staggered to avoid deformation of the plastic bucket. The weight or specific gravity of the dangerous goods contained in the chemical barrel shall not exceed the larger weight or specific gravity of the contents that can be carried. It is not allowed to use plastic drums with low hazard class to pack dangerous goods in places where high hazard class packaging is required. If the plastic drum without vent hole is used for shipment, it will release gas during storage and transportation. The single weight or volume of dangerous goods contained in the barrel shall not exceed the high limit of the world rules for dangerous goods transportation. During loading, unloading and transportation, it is necessary to avoid falling and collision with hard and sharp objects. When loading dangerous goods, do not corrode or damage the appearance of the plastic barrel.

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.

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.

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.
