Why is the chemical barrel deformed? 1. In actual use, the chemical barrel will be deformed due to the great difference in the thickness of the barrel wall. However, the machines used to make chemical barrels in China are relatively backward, and there are fewer control points for wall thickness, which results in the asymmetry of the barrel body. Therefore, when formulating the standards for chemical barrels, they are also relatively loose. In some cases, the two relatively symmetrical wall thicknesses are about 2:1. The chemical barrel with uneven wall thickness is often judged as qualified when dissecting. 2. According to relevant people, the ambient temperature is the main factor causing the deformation of plastic chemical barrel. We should control the ambient temperature of plastic chemical barrel to prevent it from deformation. The plastic chemical barrel can carry a high heat of 108 degrees, and a low heat of 70 degrees below zero. Therefore, in general, the temperature of the liquid carried by the plastic chemical barrel should be 40 degrees below zero to 60 degrees below zero. If this value range is exceeded, when the chemical plastic bucket device weighs more or the temperature is higher, protective measures should be taken for the plastic chemical bucket to avoid deformation of the plastic chemical bucket. 3. After the chemical drum is filled with liquid goods, after the lid is tightly rotated, because it is airtight, when the liquid inside is cooled, the pressure inside the drum becomes smaller, while the external pressure is larger, forming the pressure difference between the surface and the inside of the drum, causing the deformation of the chemical drum. The inspection procedure for chemical drums clearly stipulates that they should be sealed and airtight. If the liquid inside is dangerous goods, the chemical drums for Class I dangerous goods should be able to accept a pressure of 30Kpa/cm2, and the plastic drums for Class II and III dangerous goods should also be able to accept a pressure of 20Kpa/cm2.

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.

1： Measurement of the overall height of the plastic bucket. The overall height of the plastic bucket refers to the vertical distance from the bottle mouth to the bottom of the bottle. The measurement method is to place the plastic bucket on a horizontal plane, contact one end of the vernier caliper with the extreme high point of the bottle mouth, rotate the bottle body 360 degrees, read the maximum and minimum values respectively, and compare the data with the size of the design drawing to see whether they are consistent. If the specification of the plastic bucket is 40-60ml, its height should be controlled within ± 0.5mm. 2： Measurement of the outer diameter of the plastic bucket mouth. For the measurement of this part, the method is to span the scale of the measuring tool across the center of the bottle mouth, avoid the position of the mold closing line of the bottle body, rotate the circular bottle mouth 360 degrees with the main shaft close to the thread of the mouth, measure the maximum and minimum values, and compare with the bottle design drawings. The external diameter error should be controlled within ± 0.1mm. 3： Measurement of the overall diameter of the plastic bucket. For the measurement of this part, the method is to use the measuring surface of the vernier caliper to contact the measuring position of the maximum outer diameter of the bottle body, close the vernier caliper, rotate the plastic can body 360 degrees, and read the maximum and minimum values. The error of its overall diameter should be controlled within 0. 1mm. 4： Measurement of the wall thickness of each part of the plastic barrel. For the pharmaceutical plastic barrel with a circular revolving body, cut the measuring area of the symmetrical part with a knife, so that the measuring tool can enter the detection point where each part of the bottle can be measured. Strictly measure the symmetrical part of the thickness of the plastic barrel mouth, shoulder, body, and bottle bottom, and read the maximum and minimum values, Compare with the design drawing data, and check whether the tolerance of thickness dimensions of each part of the plastic bucket is within the standard range.

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.
