The reason why the plastic bucket is not broken is that it is a high molecular organic compound? Although it is called plastic bucket, and the material is also plastic, plastic can also be divided into several kinds of plastics. For example, plastic buckets are mainly made of polyethylene, polyester and other plastics by blow molding, which are mostly used to contain glacial acetic acid, tert butyl peroxide, petroleum dangerous goods, acid and alkali corrosive drugs, etc. It has outstanding characteristics, such as non fragile, non rusting, light weight, and excellent oil resistance and strong corrosion resistance. Plastic barrel plastics can be divided into thermosetting and thermoplastic. The former can not be re described and used, while the latter can be produced repeatedly. Plastic barrels are mostly used for packaging dangerous goods, which are not fragile, rustproof, oil resistant, corrosion resistant, heat preservation and moisture proof. It is mainly used to contain dangerous goods such as glacial acetic acid, tert butyl peroxide and petroleum accumulation, which are highly corrosive drugs such as acid and alkali. Plastic buckets are folded, stacked, stored, transported, stacked and canned, which greatly saves space and data in the whole process. Light weight, cold resistance, corrosion resistance, pollution reduction, super clean, meet the requirements of medical testing.

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 surface degreasing of plastic products, 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.

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 manner 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.

When the surface of the plastic bucket is labeled, the labeling surface should be flat. A "frame" can be designed on the surface of the plastic bottle, so that the label can be positioned accurately without movement. During blow molding, the first contact part of parison inflation always tends to be the first hardened part. Therefore, the wall thickness of this part is also larger. The edge and corner are the parts where parison inflation contacts, and the wall thickness of this part is small. Therefore, the edges and corners of plastic bottles should be designed as rounded corners. The rigidity and bending resistance of plastic bottles can be improved by changing the surface shape of the plastic bottle, such as making the middle of the plastic bottle relatively thin, and increasing the circumferential grooves or ribs on the surface of the plastic bottle. The longitudinal grooves or stiffeners can eliminate the deviation, sagging or deformation of plastic bottles under long-term load. The printing surface of the plastic bucket is where consumers focus their attention. The printing surface shall be flat and continuous; If the plastic bottle contains a handle, a groove, a reinforcing rib and other structures, attention should be paid not to inconvenience the printing operation during the design. The elliptical plastic bottle has high rigidity, but the manufacturing cost of the mold is high. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to selecting materials with high rigidity, it is also necessary to enhance the rigidity and load resistance strength of the plastic bottle through the shape design of the plastic bottle.

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.
