We can also use soap to add a small amount of ammonia water mixture for removal, which can also make the shell of the chemical plastic bucket more shiny. You can also use the heating method to soften the residues on the plastic bucket with the hot air of the hair dryer, and the residues can be easily removed when the viscosity of the residues becomes smaller. Of course, we can also use a very familiar eraser for erasing, but the viscosity of the residue is different, so the erasing time is also different. If there is alcohol, it can be used together with alcohol to make the erasing effect better. There are many ways to decontaminate plastic packaging barrels, not only the above, but also the essential balm we often use has a certain decontamination effect. You can refer to the above content when decontaminating.

The common cooling shaping plastic barrel is the later stage of the injection molding process, starting from the freezing of the gate and ending with the demoulding of the product. 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 prevent warping and deformation. The plastic bucket produced by this method has many advantages as well as some disadvantages. If the plastic bucket manufacturer will encounter a series of flow resistance in the injection process, part of the resistance comes from the external friction of the barrel, nozzle, mold gating system and mold cavity surface wall against the melt, and the other part comes from the viscous internal friction generated inside the melt itself. In order to overcome the flow resistance, the injection machine must apply a large injection pressure to the melt through the screw or plunger. This is not a big problem, as long as you pay attention to this problem can also be avoided!

In addition, when the plastic bucket is exposed to light, there will be temperature changes, which can be regarded as heating. The increase of temperature will accelerate the dispersion of oxygen, and then increase its oxidation rate, which will lead to thermal bonding and cracking. In addition, touching the oxygen in the air and even ozone, over fire bonding or molecular chain cracking can accelerate aging, and there are other elements such as water, high-energy radiation The media, etc. Therefore, try not to expose to the sun when using plastic buckets daily. These are the reasons why plastic drums are easy to age summarized by the manufacturer of plastic drums. Plastic buckets can be seen almost everywhere in life. Although their price is not expensive, people should also pay attention when using them. Plastic is a kind of aging material, especially under ultraviolet radiation, its aging speed will be greatly accelerated. Therefore, plastic buckets need to be carefully stored to avoid long-term storage under high temperature, direct sunlight and other environments.

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 grain size of the plastic in the plastic bucket is very harmful. The relativity of optical rotation is small or no optical rotation. The surface energy of the plastic bucket is low, which will harm the adhesion of all coatings. Because plastics are not conductive conductors and insulators in China, we cannot immediately carry out different coating on the surface of plastic barrels according to a set of electroplating process technical processing process design standards. Therefore, before the problem of information resource management on the surface of plastic barrels, it should be solved before social development, In order to better improve the bonding property of commercial coating and provide a conductive layer with excellent bonding property in coating solution. The front solution includes plastic product surface degreasing, vegetable oil cleaning, film remover, and active plastic product surface to improve coating adhesion. (1) Degrease the plastic bucket. Degreasing similar to metal manufacturing, and degreasing of plastic products can be cleaned with solvent or partial alkaline solution containing surface surfactant. Solvent degreasing is suitable for cleaning paraffin, liquid paraffin, body fat and other organic chemical stains on the surface. Commonly used solvents can not dissolve, solubilize or crack plastic products, with low melting point, easy volatilization, no toxicity, and nonflammable. Meta alkali solution is suitable for degreasing of alkali resistant plastic products. Because there are anhydrous aluminum chloride, meta alkali salt and chemical substances that carry out specific scientific research on different surfaces in this kind of standard solution. The common surface specific compounds are OP series products, namely alkyl carboxylic acid polyoxyethylene ether, which is not easy to develop into a foam plastic and does not remain on the surface of plastic products. (2) The activity of the surface of the plastic bucket. Some plastic barrels, such as polyethylene goods and ABS goods, can also be immediately coated on the surface of plastic barrels without organic chemical air oxidation. In order to better obtain high-quality coating coverage, air oxidation solution after degreasing can also be carried out for ABS products. Thin chromic acid solution diluent can be used. The typical solution secret is 420 g/L chromic acid and 200 ml/L hydrochloric acid (1.83%). The typical treatment is 65 ℃/five minutes and ten minutes, cleaning and drying. The advantages of chromic acid etching processing: the symmetrical solution of various and complicated plastic products; Defects of chromic acid etching process: actual operation risk.
