Let me share with you the advantages of using plastic buckets! In terms of convenient use of plastic buckets, the first is the plastic buckets with small capacity and light packaging weight. The main body of this kind of plastic bucket packaging is the function scheme of the handle. It is an important part of the demand thinking of the plastic bucket scheme to make the handle more labor-saving and convenient to use. There is a need for more thoughtful ideas about large capacity plastic buckets. For example, some large plastic waste barrels loaded with wheels are very convenient to push, pull and use. The second is the use of plastic buckets. Plastic barrels are usually quoted at a higher price, and they have been used. For example, many migrant workers use paint plastic buckets to hold clothes, rice and pickles. From the perspective of convenient use, we think that it is necessary to think about convenient cleaning and disinfection of plastic buckets. After all, the recycling rate of plastic drums is also a demand driven direction. Nowadays, recycling of plastic drums is very low. The recycling of plastic bottles involves recovery, equipment and other aspects, and the demand is promoted step by step.

The method to deal with bubbles in plastic bucket production is to increase injection energy, pressure, speed, time and material amount, and increase back pressure to make the mold full. Increase material temperature and flow smoothly. Reduce the material temperature and shrinkage, and advance the mold temperature properly, especially the part of mold temperature that constitutes the vacuum bubble. The gate is set at the thick part of the workpiece to improve the activity of the nozzle, runner and gate and reduce the consumption of pressing. Improve the mold exhaust condition. The uneven movement of plastic in the mold makes the air trapped in it. When the plastic enters the warm air workshop, the moisture will condense on the cold plastic. The recommended remedy is to dry the plastic. Store the polymer in the workshop for at least six hours before injection molding. The plastic bucket is used to store all kinds of liquids. When we install the liquid and screw the vent cover, we need to lie on the side for one minute first, so that the vent film can be stored vertically after soaking the liquid. The storage temperature of the plastic bucket should also be noted, which is generally about 40~50 ℃. After a certain period of storage, check whether there is expansion. If the bulge is serious, it means that the ventilation cap is not applicable

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.

Plastic barrel modification equipment What are the processing equipment for plastics? Plastic barrel modification equipment Plastic modification involves four aspects: raw and auxiliary materials used, processing equipment, modification technology and effect, and specific application. According to the plastic modification process, the processing equipment can generally be divided into four categories: primary mixing, melt mixing, pelletizing and drying. The corresponding equipment is introduced as follows: primary mixing equipment. Primary mixing equipment refers to the equipment used for mixing materials in the non melting state. The equipment used for primary mixing is almost intermittent. There are many types of primary mixing equipment, such as rotary drum mixer, double cone mixer, spiral belt mixer, Z-shaped kneader high-speed mixer, etc., but at present, the two types of widely used plastic mixing processes are Z-shaped kneader and high-speed mixer. Z-shaped kneader Z-shaped kneader, also called double arm kneader, is mainly composed of rotor, mixing chamber and driving device. The rotor is installed in the mixing chamber. The mixing chamber is a steel trough with a W-shaped or saddle shaped bottom. The upper part is provided with a cover and a feeding port, and the lower part is generally provided with a discharge port. The steel trough is jacket type, and heating and cooling medium can be fed into it. Some high-precision mixing chambers are also equipped with vacuum devices, which can discharge moisture and volatile matter during the mixing process. There are two types of rotor installation in the mixing chamber, one is tangential installation and the other is intersecting installation. In tangential installation, the movement traces of the outer edges of the two rotors are tangent; In the intersecting installation, the movement traces of the outer edges of the two rotors are intersecting. During tangential installation, the rotor can rotate in the same direction or in different directions, and the speed ratio between rotors is 1.5:1, 2:1 or 3:1. The rotor installed in intersecting mode can only rotate at the same speed because the outer edge movement traces intersect. The clearance between the outer edge of the rotor installed in an intersecting way and the wall of the mixing chamber is very small, generally about 1mm. In such a small gap, materials will be strongly sheared and squeezed. This effect can be physically modified by filling and blending.

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.

Three points are summarized for you, hoping to help you choose high-quality plastic chemical barrels. 1. Look at the material: the material of plastic determines the basic characteristics of plastic containers. Plastic packaging containers with the same or similar shapes may have extremely large differences in use performance due to different materials. The price of plastic barrels is different for different materials. 2. Look at the model: different specifications of plastic barrels have different capacities and bear different pressures, depending on the needs of your own products. 3. Look at the thickness: the thickness is very important under the same capacity, which is mainly determined by the materials in place.
