The main features of the chemical plastic bucket are as follows: the product color is bright and round: the imported food grade color masterbatch is used to make the product dyed evenly and the appearance more bright and round; 2. The wall thickness of the whole barrel is uniform and symmetrical: 360 points of wall thickness control skills make the wall thickness of each barrel very uniform; 3. The appearance of the product is clean and smooth: people rely on clothes and horses rely on saddles - each one has a specialist to recheck to ensure that there are no black spots, strains, ribbons, deformation, etc. on the surface of the barrel, so as to improve the beauty; 4. Humanized planning of the whole barrel: each barrel shape fully considers the humanization at the beginning of the planning, making the products more comfortable to carry and more convenient to pour; 5. Diversified sealing methods: aluminum foil induction seal, inner plug seal, chemical foaming seal ring seal, WAKE silicone seal, EPE seal; 6. Excellent chemical stability and anti drop test: ensure the safety of product transportation, especially the transportation of hazardous chemicals; 7. High beauty of the can body: high cost performance and strict control of concave convex deformation, which conforms to the beauty of international review; 8. The first article test of the batch includes: high temperature stacking test, hydraulic leakage test, air tightness test and drop test.

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 method to distinguish the quality of plastic drums: whether there is a relevant production license, such as the national license for dangerous goods packaging products. For the raw materials selected for the plastic bucket, brand new materials are preferred; Look at various performance indicators of the product. Such as mechanical strength, heat resistance, and solvent resistance. Now, many enterprises will first consider the price and then the quality when choosing plastic buckets. This seems reasonable, because the profit and cost are placed there. Everyone is willing that the lower the cost, the better, and the higher the profit, the better. Many large and powerful enterprises will have their own proprietary departments to analyze the possible profit and loss risks of their products, which must include costs and profits. Now plastic buckets are indispensable in all major industries, because they can store goods more efficiently. However, the barrier performance of different quality plastic buckets to oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times. Therefore, when selecting plastic buckets, we must pay attention to that the quality of plastic buckets cannot be judged only by their appearance, but the basic characteristics of plastic containers. When selecting plastic containers, be sure to fully understand the relevant properties of plastic. Plastic barrels are generally made by molding. Different molding methods often have a great impact on the performance and cost of products.

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!

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.

Plastic barrels are the most widely used container products nowadays. Generally, plastic barrel manufacturers have a variety of processing methods. Plastic barrels are made of PE, mainly ethylene, and some propylene and hexene are used as copolymers. Then, under the action of catalyst, some polymerization processes are used to produce plastic buckets. The production methods of plastic buckets include extrusion, blow molding, injection molding, rotational molding, etc. Blow molding, extrusion molding and injection molding are commonly used. Now let's get to know. First choice, extrusion mode: extrusion mode is also called extrusion blow molding, which is a plastic molding process. Extrusion is to heat the plastic raw materials to make them appear viscous flow, then pressurize them, and then cool them through the extrusion mold. Extrusion is a method of manufacturing hollow thermoplastic parts, which is generally used for bottles, barrels, cans, boxes and other containers. The common extrusion material is high-density polyethylene. The process of extrusion process is: solid plastic plasticization, molding, and shaping. According to the physical state, the extrusion method can also be divided into dry extrusion and wet extrusion. In addition, the compression method for plastic is also different, including continuous extrusion and gap extrusion. The extrusion mode has the following advantages: continuous, high productivity, low investment, low cost, simple operation, easy process control, and uniform quality.
