In the market, there are many miscellaneous barrels (all kinds of recycled waste plastics may contain dirty PC materials, which are toxic and carcinogenic); pet barrels are mainly used in supermarket channels, and they are disposable packaging containers like ordinary beverage bottles, and the National Quality Supervision Bureau does not allow them to refill water; in a real sense, PC barrels are now less and less, belonging to pure drinking water, Ideal can container for environmental protection and economy.
Polycarbonate material is colorless, transparent, heat-resistant, impact resistant, flame retardant, and has good mechanical properties at ordinary temperature. Compared with polymethylmethacrylate, polycarbonate has good impact resistance, high refractive index, good processability, and UL94 V-0 flame retardancy without additives. However, the price of polymethylmethacrylate is lower than that of polycarbonate, and large devices can be produced by bulk polymerization. High quality polycarboxylate is a high-end product in the product series of raw material suppliers such as Bayer, and the price is relatively high.
Genuine PC barrel: the appearance is relatively transparent and smooth, the can body is light blue and has a faint blue light, without impurities and black spots, the sound of tapping the can wall with fingers is crisp, and the toughness is strong. The damage life is at least 3 years.
Poor quality water bucket: the appearance is light blue or milky white, the color is dim, the transparency is poor, there are impurities and many black spots on the tank wall, the sound of knocking the tank wall with fingers is dull, the falling performance is poor, and the toughness is poor. It is easy to crack and deform in the process of use, and there is no manufacturer’s logo on the bottom of the tank. When filling with poor quality bottles, the taste is poor and there is peculiar smell.
In order to save the cost, the black heart manufacturers use recycled waste materials (including waste optical discs, medical waste, and recycled dirty buckets, etc.) and color masterbatch additives, brightener, etc., and then thermoplastic again. Recycled materials can be used to make industrial products, but once again thermoplastic will produce a lot of toxic carcinogenic impurities, which can not be used to make food and beverage packaging containers, especially the additives themselves are highly carcinogenic. What’s more, some factories recycle medical waste and waste optical discs and other materials to make inferior drinking water buckets.
The 3-5-gal bottled water filling machine is a full-automatic filling equipment for 3-Gal and 5-Gal buckets in pure water plant or mineral water plant. The equipment is easy to operate and can be operated by only 1-2 workers. It integrates disinfection, washing, capping, capping and delivery. It adopts three-phase AC 380V power source, and is widely used in cities and towns, industrial and mining enterprises and individual units.
The equipment adopts the microcomputer control system and pneumatic control system with reliable performance, simple operation and simple maintenance. It can effectively prevent the secondary pollution of purified water or mineral water in the filling process and achieve the real aseptic filling. It is the ideal pure water / mineral water filling equipment in China at present.
