No more than 3 days. Food grade plastic buckets are made of PC and can store water for up to 3 days. After three days, bacteria and parasites will reproduce in the water, causing harm to the human body. The materials of plastic drums are mainly made of polyethylene, polypropylene and other blow and injection molded plastic products. Shanghai plastic products are used for outer packaging of liquid and solid items in chemical, pesticide, pharmaceutical, food, electronic equipment, electromechanical and other fields. Industries.
You can hold boiling water, but boiling water in this type of bucket is not drinkable.
Plastic itself contains certain chemicals. Some of the organic polymer structures in plastic will break down into small organic molecules.es. Boiling water will undoubtedly speed up this process. Small molecular organic substances are distributed in water, so they are always dangerous and hygienic. Do not use it to contain boiling water.
In daily drinking water, bottled water such as mineral water should not be placed at high temperatures or in areas exposed to direct sunlight for a long time. The high temperature inside will also dilute the harmful substances out of the bottle. so this Seed water should be stored in a room temperature or low temperature environment.
At high temperatures, industrial plastics will dilute various harmful or even toxic substances depending on their composition, causing indoor water pollution. If people drink it, it will affect their health and even cause harm. . Cause serious consequences such as poisoningent. To store boiling water, choose a container made of 5pp material, which is relatively safe.
Detailed information:
The main performance characteristics of engineering plastics are:
(1) Compared with general plastics, it has excellent heat and cold resistance, excellent mechanical properties in a wide temperature range, and is suitable for use as structural materials;
< p>(2) Good corrosion resistance, less affected by the environment and good durability;(3) Compared with metal materials, it is easy to process, has high production efficiency, can simplify procedures and reduce costs;
(4) It has good dimensional stability and good electrical insulation;
(5) It is lightweight, has high specific resistance and features exceptional friction reduction and wear resistance.
