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.

When it comes to plastic packaging barrels, we are no strangers. Most of its materials are made of polyethylene, polypropylene and other plastics by blow molding and injection molding. They are used for the external packaging of liquid and solid objects in chemical, pesticide, medicine, food, hardware, electronics, electromechanical and other industries, and play an important role in our daily transportation. Now let's introduce the functions and characteristics of plastic packaging barrels. First of all, it has beautiful appearance, smooth inside and outside, seamless without welding, light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and convenient transportation. It has a long service life and can be used for at least one and a half years under normal filling, transportation and loading and unloading conditions. Its product technical parameters are strictly in accordance with national standards, and the appearance design and size of the product can also be customized according to needs. The temperature that can be used for hot filling shall not exceed 60 ℃ generally. After hot filling, the lid and stacking shall be closed after the contents are fully cooled and cooled to room temperature. If the easily dispersed chemicals are contained, the cover with exhaust function can be used to avoid the danger of overpressure during transportation and ensure the sealing performance of the liquid.

Chemical plastic bucket has good heat resistance and cold resistance, good hardness, tensile strength, electrical insulation performance and toughness, and good chemical stability. It is almost insoluble in any organic solvent at room temperature, resistant to corrosion of various acid, alkali and salt solutions, and has excellent resistance to environmental stress cracking and thermal stress cracking. Its surface hardness is high, Good dimensional stability. Chemical plastic bucket is easy to use, economical and durable. With the development of internationalization, plastic bucket has gradually become the mainstream product of liquid packaging. It can contain Class II and III dangerous goods. The liquid density for Class II dangerous goods is 1.5g/cm3, and the liquid density for Class III dangerous goods is 1.8g/cm3. The product structure is reasonable, firm and solid, which can be directly loaded and unloaded by forklift, and can be stacked and stored. The plastic container is light and not fragile. Chemical plastic buckets, plastic pots and bottles for daily food storage are mostly made of polyethylene or polypropylene, of which polyethylene is more common. PVC can also be made into containers such as barrels and basins, but like film, it cannot hold food, especially oil and wine. There are also pulse formaldehyde plastics commonly known as "Dianyu" and melamine formaldehyde plastics commonly known as "melamine". The raw materials contain formaldehyde. In the production process, if the polymerization is not good, free formaldehyde may appear in tableware. Formaldehyde is a highly toxic substance. If it is mixed with food, it will seriously damage human health. Therefore, good quality "electric jade" and "melamine" tableware and containers must be used. For inferior products, the relevant departments should strictly check to prevent them from coming out of the cage. Although polyethylene container can be used to hold food, it should also be noted when it is used to hold oil. Because polyethylene is soluble in oil, if it is stored for a long time, the color and taste of edible oil will also change, and even cannot be eaten, which is harmful to health.

For chemical drums, it is very important to master the temperature. Because temperature has a significant impact on the function of plastic extrusion and parison, improving the extruder temperature can reduce the viscosity of the melt, improve the fluidity of the melt, and improve the screw speed without affecting the mixing and plasticization of plastic. To achieve this goal, we can use electronic temperature controller to make the process temperature stable and save energy significantly. It must be well understood that humidity will affect the drying rate of chemical drums. When the relative humidity in the bucket is low, the pressure difference between the surface and the water vapor in the dryer is large, and the drying speed is fast. The isolation function of chemical drums from oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times, and the basic characteristics of plastic containers should be grasped. Therefore, when selecting plastic containers, it is necessary to fully understand that plastic related functional chemical barrels are generally made by molding. Different molding methods often have a great impact on the function and cost of products.

What are the functions of resin in plastic bucket production? In the same kind of plastics, when the filler content is high or the inorganic filler in the filler is increased, the shrinkage rate is small. The mold structure that is conducive to improving the molding pressure, increasing the plastic mold filling fluidity and making the plastic part dense can reduce the shrinkage rate of the plastic part. Any process factor that can make the plastic part dense and overflow the low molecular volatile matter before molding can reduce the shrinkage of the plastic part, such as preheating and pressurizing the phenolic plastic before molding. After heating, compacting and mixing in the barrel of the injection machine, the process of transforming loose powder or granular solid into continuous homogenized melt is called plasticization. Homogenization includes four aspects, that is, after the material is plasticized, the composition, density, viscosity and temperature distribution in the melt must be uniform. Metering refers to the preparation work that can ensure the injection machine to discharge the plasticized melt out of the barrel at a constant temperature, pressure and quantity through the plunger or screw, which needs the injection machine to control the plunger or screw during the plasticizing process.
