Have you ever been bothered by the issue that when freezing the water bottles, they just cracked or even broke in the freezer? We will give you a detailed introduction to the relevant information about freezing water bottle explosions, to help you solve this common problem more calmly.
The Dangers Of Exploding Water Bottles
The explosion of the water bottle will lead to a series of adverse consequences. You should be aware of this and take it seriously.
Physical And Psychological Injury
The explosion of frozen water bottles is sudden and powerful, which will cause serious harm to the human body. The sharp objects, such as glass or plastic fragments produced by the explosion, may scratch the skin, eyes, and other parts, resulting in cuts and abrasions. In severe cases, if the fragments enter the eyes, they may also cause vision damage.
In addition, the instantaneous impact force of the explosion will produce a huge sound, causing a strong shock to the user. Especially for children and the elderly, when they meet abrupt explosions, they may develop psychological shadows.
Freezer Damage
The force and splashes generated by the explosion of a frozen water bottle can cause the freezer to break down directly.
The debris of the explosion may hit the door panel, the inner liner, and other core components, which may lead to the freezer shell sagging and breaking. If the fragments get inside the freezer, they may get stuck in the cooling fan, damage the temperature control sensor, and affect the normal cooling function of the freezer.
What’s worse, if it causes serious damage and cannot be repaired, you need to replace the freezer.
Environment Mess
After a water bottle explodes, the ice water inside and the fragments of the broken water bottle will splash everywhere, seriously messing up the environment.
The inside of the freezer and even the floor, etc., will be soaked with ice water. At the same time, glass or plastic fragments may also be mixed in the water, which not only makes cleaning difficult but also easily causes secondary scratches during the cleaning process.
Moreover, the water stains may permeate into the freezer crack and the gaps on the floor. If accumulated for a long time, they can easily breed mold and bacteria, seriously affecting hygiene.
Why Does The Frozen Water Bottle Explode
Limited Space
If the space inside the water bottle is very limited and there is not enough room to hold the ice cubes, it will cause compression on the bottle wall. As the freezing process progresses, the pressure inside will continuously accumulate. When the pressure goes up to the bottle’s tolerance limit, the bottle will expand, eventually causing an explosion.
Bad Bottle Material
The material factor will directly affect the possibility and intensity of the explosion.
Glass and ceramic materials have poor toughness, so they cannot disperse the pressure caused by ice expansion through their own deformation. Once the internal pressure reaches the critical point, the bottle will directly undergo brittle fracture and burst instantly.
Stainless steel has high strength, good toughness, and a strong ability to resist expansion pressure, which makes it a wonderful material. However, if it is a thin-walled sealed type, the pressure created by ice formation and expansion may still exceed its endurance limit, thus causing the bottle body to distort or break.
Food-grade soft plastics like PP have a better elastic performance. The plastic can slightly deform and buffer part of the freezing pressure, which will bring a relatively low explosion probability. However, hard thin plastics lack sufficient toughness and have poor deformation ability, which makes them prone to cracking.
Overfilled Water
The amount of water held can determine the risk of bottle explosion. If you fill the bottle with too much water, there is no room for water to freeze, which can suddenly increase the inside pressure and eventually cause the bottle to explode.
Poor Sealing Performance
The performance of sealing directly affects the pressure release. If you tightly close the lid, the completely sealed internal space would make the pressure generated by the expansion of freezing water hard to release. Instead, it would continuously act on the bottle wall, eventually bringing out an explosion.
Fast Freezing
The rate of freezing determines the rate of freezing, and it can affect the strength of the shock pressure.
If you place the water bottle directly in the freezer with low temperature, the water will quickly freeze, and it will expand rapidly. In a short period of time, a huge instantaneous pressure will be generated inside the bottle, exerting a strong impact on the bottle wall. This can easily overwhelm the water bottle and cause it to explode.
How to Prevent Water Bottles From Exploding When Frozen
Leave Space For Expansion
It is quite important whether there is sufficient space reserved for the expansion of the water.
When filling water, if you leave sufficient reserved space, the part where water freezes and expands can be well accommodated, and the pressure can also be effectively buffered, ultimately significantly reducing the risk of explosion.
Choose The Right Bottle
Since choosing the right material is crucial for preventing explosions, you need to try to avoid high-risk materials.
You must resolutely avoid using glass and ceramics because these materials are very brittle and prone to cracking when freezing water.
Secondly, even if it is made of stainless steel, you should choose a thicker layer because a too-thin layer cannot withstand excessive pressure and may eventually explode.
You’d better choose food-grade soft plastic, such as PP. It is elastic and can cushion pressure without cracking easily. Of course, just in case, it’s best to choose the thicker ones.
Create The Good Freezing Environment
If the freezing process of water is relatively smooth, the impact force brought by expansion can be gradually released, and accordingly, the impact on the bottle will be smaller. Therefore, if you want to avoid the possibility that your water bottle will explode during freezing, please pre-cool it in the refrigerator and then slowly transfer it to the freezer.
Loosen The Lid Before Freezing
If you want to reduce the risk of the bottle exploding, do not tighten the lid before freezing. Because the gap it forms can slightly relieve the pressure of the gas or the water vapor produced by expansion. This can prevent the pressure from accumulating without limit and significantly reduce the probability of explosion.
Choose The Correct Placement Method
A proper placement method can also reduce the risk of the water bottle exploding.
When you freeze water, please place the water bottle flat on the freezer rack instead of standing it upright. Because if it is flat, the ice blocks can be evenly distributed and will avoid excessive local pressure on the water bottle. This can effectively reduce the ice water bottle explosion situation.
FAQ
When Freezing A Water Bottle, How Much Space Should Be Reserved To Ensure Safety?
When water freezes, its volume expands by about 9%. To reserve sufficient space for expansion, it is highly recommended that you fill the bottle with water to 70% to 80% of its capacity.
Is There An Explosion Risk If The Freezing Time Is Too Long?
There is a risk. Once water is completely frozen, although its volume will no longer change, if a water bottle is left in the freezer for a long time, the pressure inside the bottle will remain at a critical state, which will increase the probability of the bottle breaking or exploding. Therefore, after the water is frozen for a long time, you should take it out in time to avoid exploding.
Can Disposable Plastic Water Bottles Be Used To Freeze Water?
It is not recommended to use. The disposable plastic has weak resistance to deformation. When frozen, the bottle body will deform severely and is very easy to break. Moreover, some disposable plastics may release harmful substances in low-temperature environments, thus posing health risks.
Why Are Carbonated Drinks More Likely To Explode When Frozen In A Water Bottle?
On the one hand, when water freezes, its volume expands, which can exert pressure on the bottle wall. On the other hand, in a low-temperature environment, the solubility of carbon dioxide in the liquid will significantly decrease. This results in a large amount of gas that was originally dissolved in the beverage being released, causing the pressure inside the bottle to rise sharply.
What Should You Do If You Find The Water Bottle Is Swollen And About To Explode?
First of all, do not touch, squeeze, or open the bottle lid; Secondly, slowly transfer the water bottle to a room-temperature and cool environment, and let the ice melt slowly. Then, wait until the bottle body returns to normal and the pressure has completely dissipated before processing. Keep a distance throughout the process to prevent sudden breaks from causing injuries.
