Balloons symbolize innocence, freedom, peace and happiness.

For as long as we can remember, balloons have been our means of play.To a little bigger we began to resist the balloon, that only naive people would touch this thing, I do not know the day, see the TV qi put peace balloons, just understand the balloon is not as simple as we imagine;Later, when we got married, the balloons in the bridal chamber made us very happy.Balloons - you're not easy.

Today we'll take a look at how balloons are made.

Production of raw materials

Balloons don't grow on trees, but they do come from trees, because you can't make balloons without the milk of a latex tree.Latex is a malleable substance, but it needs to be made into rubber to give the balloon enough elasticity to inflate up to five times its original size.

The balloon was originally in liquid form, the milky white milk of the rubber tree. A powdery dye can change the color of the milk.The mixture is then heated and activated to convert the latex into latex.

Production tools

The instruments are rows of porcelain that look like small light bulbs, the mold used to make balloons.

Preproduction preparation

One. Before production, the mold shall be soaked in citric acid and all surface impurities shall be burned off.Any impurities in the mold may defect the balloon

Two, in order to make the latex in the mold to adhere to the uniform mold is not sticky, mold need to be coated with calcium nitrate.Calcium nitrate is a coagulant that allows the latex to adhere to the mold.The next step is to dry the mold, leaving only a thin film of calcium nitrate.

The balloon shape

Next, it is the sticky mold stage of latex. The assembly line will send the processed mold to the pre-prepared latex bucket. The bucket rises slowly and completely covers the mold, forming the shape of a balloon.

  • Balloon formation

The formed balloon is heated in the oven for five minutes to make the skin firmer.Once the balloon is firmly heated, it can be rinsed to remove any remaining material from the surface.

After cleaning, the nozzle of the balloon needs to be processed

Two nylon brushes on the assembly line roll down the warm top of the balloon, which is still soft enough to be rolled into a balloon nozzle.

When the balloon even under the high temperature of 170 ℃ after baking, the balloon can be converted into elastic rubber.

High temperature activates the sulfur and zinc oxide in the milk mixture to strengthen the molecular bonds between milk molecules. It is also because of the strong molecular bonds between the molecules that the balloon is so elastic and malleable that it can be hard to break after being inflated.

Balloon release: spray water between the ceramic mold and the balloon to loosen the skin.Use a row of carpet MATS, one row at a time, to peel the balloons from the mold.


The last step is the inspection of the balloon, which is also a key step: check whether the balloon is broken, damaged, and impurities.
