HBzhan Content Introduction: The plastic water tank adopts a one-time rotation molding process for one-time molding, and the whole is demolded. The barrel body is like a glass bottle, without any welds. The PE water tank is made of LLDPE food grade corrosion-resistant raw material (linear low-density polyethylene) from Hyundai Company in South Korea, with a milky white granular color. It is then ground into a powder like environmentally friendly raw material during production. The appearance color of plastic water tanks can be made into white, orange, black, blue, etc.
　　
At present, there are numerous PE rotational molding products in the mainland market, with uneven product quality. Each manufacturer claims that their product quality is good and what materials are used for production, which can be said to be exaggerated. However, the country has not yet issued relevant rotational molding product quality system standards, and coupled with a lack of understanding of plastics in the past, it is easy to confuse the public and consumers often cannot control their consumption trends. How can we distinguish between such a vast amount of information, which is good and which is added by merchants? Or simply put, how can I buy a suitable PE water tank or rotational molding product. The following methods can serve as reference standards for purchasing PE products and rotational molding containers.
　　
Purchase rotational molding products, whether they are large or notPE storage tankMedium tonnage water tanks, water towers, dosing tanks, other turnover boxes, drums, etc. You must purchase products from large manufacturers with strong capabilities, such as "Haiqiang Plastic".
After selecting a reputable manufacturer, you also need to have a detailed understanding of the product's raw materials, origin, production location, and detailed parameters such as thickness, weight, diameter, etc. Only by understanding these can you make a reference to which manufacturers are telling the truth and which are deceiving you. (If the manufacturer tells you that imported raw materials are used, please have a detailed understanding of which country, company, and model they are from. Currently, the raw materials are very chaotic, and some countries' raw materials are not as good as domestically produced materials, such as Mexico, which is owned by Hyundai Motors of South Korea.)
　　
All of this is done well, and the only thing you can do is wait for the manufacturer to deliver the goods to you. After you receive the goods, you can check if they match what you previously discussed, and follow the testing steps
　　
Check if the outer packaging is intact and if there are any scratches on the product. If there are slight scratches, it is normal wear and tear on the goods, and there is no need to investigate. If it is serious, you should contact the shipping company
　　
Measure the detailed parameters of the product, mainly whether the size, thickness, and weight are within the range agreed upon before shipment
　　
Check the condition of the product. Products made from brand new materials are generally milky white and belong to the new category. If you want to test the type of raw material, you need to go to the corresponding testing company for testing.
　　
Smell the product odor and see if there is a smell of plastic glue. If there is, then it is notPE materialIt was done. At least it's not made of pure PE material.
