There are two things you can try:
1. Put the two buckets in a basin larger than them, soak them in water, and open them the next day.
2. First pour boiling water, preferably freshly boiled, into a bucket (preferably more than half), pour it out at a speed after 1-2 minutes, and then pour cold water, it is best to add ice cubes, so that the temperature of the water is as low as possibleWater (preferably ice) can be smoothly separated shortly after that.
The main raw material for the production of plastic barrels is polyethylene (PE), referred to as PE, which is a polymer organic compound formed by the addition of ethylene. Polyethylene is recognized as the best material for food contact in the world, which is non-toxic, tasteless, odorless, and meets the hygiene standards of food packaging.
Polyethylene film, light and transparent, has moisture-proof, anti-oxidation, acid resistance, alkali resistance, general air tightness, excellent heat sealability and other properties, known as the "flower of plastic", is the most important material for plastic packaging printing.
Characteristics of plastic barrels
Exterior features: The soft plastic barrel is beautiful, light weight, good strength, impact resistance, corrosion resistance, foldable, non-toxic and odorless, and easy to transport. The product is suitable for the packaging of various salted liquid foods, condiments, medicine and health products, wine and fine chemical products. Features::
It is acid-resistant, alkali-resistant, high-temperature resistant, non-toxic, sterile, odorless, and has excellent stretch resistance and impact resistance.
Product advantages: folding, stacking, warehousing, transportation, stacking, canning, the whole process greatly saves space and materials. Lightweight, cold-resistant, corrosion-resistant, reduced contamination, ultra-clean, and meets the requirements of medical testing.
Product use: food packaging: sauce, oil, vinegar, condiments, milk, lactic acid and other packaging.
Beverage packaging: wine, sake, fruit wine, mixed wine, fruit juice, mineral water, etc.
Chemical packaging: fine chemicals, liquid fertilizers, pesticides, treatment agents, cleaning agents and other packaging.
Medical packaging: packaging of medical reagents, disinfectants, developers, setting solutions, distilled water, etc.

Fill hot water first, heat it for a few minutes and change it to cold water, and that's it. The principle of thermal expansion and cold contraction. Use hot water to swell the outside bucket, change the cold water to quickly shrink the bucket inside, and it will automatically disengage.
-
The principle of thermal expansion and contraction Use enough hot water to place the bucket that needs to be pulled out in hot water, overflow the lower third of the barrel, and touch the outer barrel to be soft, and you can easily pull out the bucket inside. Welcome.
-
You can put two buckets in a larger basin filled with warm water, put the junction of the two buckets in the basin and go around, and then slowly turn it up, I have been doing it for a long time before, and many methods have been tried, and then use this method to rotate up, you can also try it.
-
Pour hot water to heat and expand the air between the barrels, so that it is easy to take down.
-
The kettle boils water, scalds the outer barrel, the outer barrel expands when heated, and then it can be broken with force. But be careful not to burn.
-
Put some cold water in the middle and turn the bucket to lift it up.
-
Pour boiling water around the outside bucket and cold water on the inside.
It depends on how you position the two lenses.
If the distance between them is greater than the sum of their focal lengths, it is equivalent to a Galilean telescope, which can increase the angle of view of the object, that is, it appears to be close. >>>More
