When it comes to plastic barrels, I believe everyone is quite familiar with them! Plastic barrels are everywhere in our lives, which shows their wide application. They are highly regarded for their durability and ease of use. So, how well do you understand the characteristics of plastic barrels? Let's take a look at the detailed introduction provided by the plastic barrel manufacturers!

Plastic barrels are mainly used for packaging solid and liquid products and have good characteristics. They are not easy to break, do not rust, are lightweight, and have excellent oil resistance and strong corrosion resistance. They are often used for packaging hazardous materials that require insulation, moisture-proofing, pressure resistance, and corrosion resistance.

The materials for plastic barrels are mostly made from polyethylene, polypropylene, polyester, and other plastics through blow molding, injection molding, vacuum forming, and rotational molding. They are widely used to hold liquids and solids in industries such as chemicals, pesticides, pharmaceuticals, food, hardware electronics, and electromechanical. Specifications range from 1L to 25L for open and closed plastic barrels, which can be used for storage or transportation.

Plastic barrels do not leach harmful substances. PC polycarbonate, PP polypropylene, and block copolymers are inherently harmless materials, and their melting points are all above 200 degrees. They do not decompose when boiled in water. However, many additives are added during the molding process, such as enhancers, toughening agents, anti-aging agents, antioxidants, and plasticizers. These additives are also not toxic, and the content requirements for food-grade plastic barrel additives are strict, making them relatively easy to volatilize.

The inner liner of the plastic barrel is marked with capacity height. When customers use ton barrels to fill materials, they can clearly see the filling height through the transparent inner liner for accurate control. The inner liner is made from high-density polyethylene raw materials, pure materials, without any recycled materials, ensuring the strength and toughness of the product. Plastic barrels come in various colors, with white being the standard ton barrel, while blue and black are light-blocking barrels that can resist ultraviolet rays and are resistant to light aging.

The materials for plastic barrels are mostly made from polyethylene, polyester, and other plastics through blow molding. They are commonly used to hold acetic acid, tert-butyl peroxide, petroleum-based hazardous materials, and strongly corrosive acidic and alkaline drugs. They have outstanding characteristics, such as being unbreakable, rust-resistant, lightweight, and having good oil resistance and strong corrosion resistance. Plastic barrels can be classified into thermosetting and thermoplastic types, with the former being non-recyclable and the latter being reusable.

Plastic barrels are often used for packaging hazardous materials. They are unbreakable, rust-resistant, oil-resistant, corrosion-resistant, and provide insulation and moisture-proofing. They are commonly used to hold acetic acid, tert-butyl peroxide, and other hazardous materials, as well as strongly corrosive acidic and alkaline drugs.

200L plastic barrels are commonly used, but after a period of use, their brightness may not be very noticeable. What factors affect this? Next, our staff will briefly introduce some related knowledge.

Mold issues: 1. The mold cooling system leaks water, and long-term operation of the mold leads to corrosion and damage of the sealing system. Water leakage occurs at certain positions of the mold, causing water to flow into the mold, resulting in dull barrel walls. The sealing rubber strip needs to be replaced to address the leakage issue.

2. The mold exhaust system is poor, causing excessive gas to remain in the mold during production, leading to a lack of gloss. Therefore, it is necessary to check and repair the mold exhaust system in a timely manner.

Raw material issues:

1. First, understand the material properties and reasonably adjust the process formula. For example, if the flowability of the gel is poor after heating the material, it will lead to a lack of brightness on the outer wall of the 200L plastic barrel. Adding a small amount of low-pressure resin and increasing the temperature of the material can help address the issue.

2. If the material is significantly affected by external moisture, a large amount of water vapor generated during production can cause the walls of the 200L plastic barrel to appear dark and dull. Secondary drying of the material is required to resolve the issue.

3. If recycled materials are added in large proportions during the production of plastic barrels, it can lead to a decrease in the brightness of the barrel's appearance. Reducing the proportion of recycled materials and appropriately adding low-pressure resin can help solve this problem.

This concludes our introduction to the factors affecting the brightness of plastic barrels. We hope the above content can be helpful to you.

As a medium for storing items in our daily lives, plastic barrels indeed provide us with great convenience. Plastic barrels are lightweight and easy to use, making them very popular. Frequent users may find that plastic barrels are not easy to break. Why is that? Let us explain in detail.

1. Plastic barrels are high molecular organic compounds.

2. They can exist in various forms, such as liquids, solids, colloids, and solutions.

3. They have a wide range of uses and can be presented in various forms through different processing methods.

4. They come in various types due to the different monomers that make up the plastic barrels.

5. Plastic barrels have different properties and can be molded.

Plastic barrels are a popular storage container. However, plastic barrels can become deformed. How can we prevent this from happening? Let us explain in detail.

1. When transferring and handling plastic barrels, as well as during daily use, be careful to handle them gently.

2. During storage and transportation, the ground should be level to prevent the barrel from tilting and avoid contact with sharp objects that could puncture the barrel. When filling and sealing, it is advisable to use a rubber mallet weighing less than one pound. First, press tightly on the tear strip opening, then evenly tap down the lid along the outer circumference of the barrel top. The tapping force should not exceed 8KG, and the contact between the rubber mallet and the barrel lid should be parallel and not tilted; otherwise, it may easily break the lid.

3. During storage, plastic barrels should be placed with the opening facing up.

4. In containers, they should be stacked tightly and securely or have sufficient support and reinforcement. A layer of thin boards should be placed on top of every two layers of plastic barrels before stacking to avoid shaking during transportation. A layer of thin boards should be placed on top before stacking to prevent excessive localized stress on the barrels, which could lead to unnecessary losses.

The pre-treatment of the molding materials conducted by the 200L plastic barrel manufacturers before production includes analyzing and inspecting the quality of the molding materials and preheating and drying them.

1. Analyze and inspect the quality of the molding materials according to the requirements of the process characteristics for injection molding. Inspect the moisture content, color, fineness, uniformity, and the presence of impurities in the materials, and test indicators such as thermal stability, fluidity, and shrinkage rate. If problems arise during inspection, timely measures should be taken to resolve them.

2. Preheating and drying: For hygroscopic plastics such as nylon, polycarbonate, and ABS, sufficient preheating and drying should be carried out before molding according to the moisture content requirements allowed by the molding process to remove excess moisture and volatiles from the materials to prevent bubbles and silver streaks from appearing in the molded parts, and also to avoid water degradation during injection.

In injection molding production, to facilitate the easy release of plastic parts from the mold, some mold cavities or cores need to be coated with a release agent. Common release agents include zinc stearate, liquid paraffin, and silicone oil. For soft products containing rubber or transparent products, it is not advisable to use release agents, as this will affect the transparency of the products.

If it is necessary to change the type of plastic, replace materials, or change colors during production, or if thermal decomposition or degradation reactions are found during the molding process, the injection machine's barrel should be cleaned. Generally, for plunger-type injection machine barrels, the barrel must be disassembled and cleaned. For screw-type barrels, the empty injection method can be used for cleaning. When using the empty injection method to clean screw-type barrels, if the molding temperature of the plastic to be replaced is lower than the molding temperature of the residual material in the barrel, the temperature of the barrel and nozzle should be raised to the molding temperature of the plastic to be replaced, the power should be cut off, and the recycled material of the plastic to be replaced should be added, and continuous empty injection should be performed until all residual material is expelled.

People usually stack plastic barrels after filling them to reduce storage space, which requires the plastic barrels to have sufficient strength to withstand a certain amount of weight. Therefore, many people pay attention to the strength of plastic barrels when purchasing them. So, what factors affect the strength of plastic barrels? Below, professionals from the 200L plastic barrel Manufacturer will introduce this to us.

Factor 1: Temperature

For plastic barrels, controlling the temperature is very important. This is because temperature has a significant impact on the performance of plastic extrusion and the properties of the molded blanks. Increasing the temperature of the extruder can reduce the viscosity of the melt, improve the fluidity of the melt, reduce power consumption, and increase the screw speed without affecting the mixing and plasticizing effect of the plastic. To achieve this purpose, we can use electronic temperature control instruments to stabilize the process temperature while significantly saving energy.

Factor 2: Relative Humidity Inside the Barrel

Humidity affects the drying speed of plastic barrels, which is relatively easy to understand. Therefore, the relative humidity inside the plastic barrel is also a major factor affecting product quality. When the relative humidity inside the barrel is low, the pressure difference of water vapor between the surface and the drying machine is large, resulting in a fast drying speed; conversely, it is slow.

Factor 3: Melt Pressure

High melt pressure promotes better plasticization and uniform mixing and coloring, especially for blends of high-density polyethylene and low-density polyethylene, and reduces the crystalline spots and cloudy patterns on the molded blanks. Therefore, we will adopt increasing the screw speed to increase the melt pressure.
