How does a balloon production plant make colorful balloons out of natural latex?

<>. First, the worker poured the white natural latex into the raw material tank, and then added the pre-prepared mixture to it. This is made from zinc oxide.

Dyes made with more than 10 kinds of excipients such as pigments and antioxidants.

Not only can the latex be activated to prevent premature solidification, but it can also add a variety of colors to the balloon. When the raw materials in the tank are thoroughly stirred, the high-pressure nozzles on the assembly line will first clean the balloons of different sizes, and then the machine in front will soak the surface of the balloon with a thin layer of coagulant. The purpose of this is to make the latex perfect for the garment on the balloon in the next step of the glue feeding process.

<>. Second, the next latex raw material grass filled with different colors will be soaked in a layer of glue liquid after drying the coagulant balloon at the same time, and then through the drying and shaping, you can follow the conveyor belt to the automatic curling line, here, the rollers on both sides of the machine will roll out a familiar blow port for the film while the mold passes. Next, in order to make the finished balloon flexible and less likely to burst, the formed balloon is filled with calcium carbonate.

The solution is soaked for 30 minutes, until the texture of the balloons is vulcanized, and then they can be sent to the demoulding line.

<>. 3. At this time, the nozzle under the jurisdiction of the track will blow up the sphere passing here, and the two rollers at the top will quickly demould the balloon while the balloon is close. In this process, partially damaged or failed balloons are manually removed, while the balloons that are fully demolded are collected along the discharge pipe and then transferred to offset printing.

In the assembly line, workers print various festive patterns or words on the surface of the balloon according to different customer needs. Now after the completion of the printing process, the balloon needs to pass a variety of different items of strict sampling, in order to remove the local thinness and defective products with bubbles or traces, and finally put into the professional cleaning equipment, rinse with 70 degrees of hot water for 20 minutes, until the surface of the balloon becomes smooth and not easy to stick, it can be packaged and shipped.

They just compressed the natural latex, then poured a little nitrogen into it, and then used a robotic arm to shape it into a balloon.

Grinding, embossing, grinding and embossing, that's how it became such a shape, it's simple.

Rubber Balloons Natural latex is a white, milky liquid. They are usually transported by tanker from the producing country to the United States, where they are transported by train or truck to the balloon factories. The raw materials for the manufacture of balloons include hardeners, catalysts, greases, dyes and water, etc., all of which are mixed in large open-top cylinders and then transported to the balloon production line below.

At present, almost all balloon production lines are produced by metal die immersion method. For example, the mold used to produce a round balloon is like a small light bulb. However, before the metal mold is immersed in latex, the metal mold must be immersed in a coagulant mixture made of calcium nitrate, water and oil, and when the coagulant is dry, the balloon production process can begin.

The second step of the process is to immerse metal molds of different shapes into an open-top vat containing latex. Because the top-to-bottom immersion method is used, it is common to see the top of the balloon being the thickest and the neck being the thinnest. When the latex dipping process is complete, the rudimentary latex film is rolled up into the shape we normally see by a row of rotating brush heads.

This process is carried out without the latex film cured.

Now, the almost-finished balloon is rinsed with hot water along with the metal mold to remove the remaining calcium nitride, and then placed in a roaster at 200-220 degrees Fahrenheit to harden the latex film for 20-25 minutes. After hardening, the balloon is removed from the metal mold for printing or packaging shipment, and the metal mold is used repeatedly.

Answer]: 25 (.)

This product is a kind of inflatable balloon, which seems to be classified as 9506 62 "inflatable ball", but the balloon does not belong to sporting goods and cannot be classified in Chapter 95, but should be classified in Chapter 40 rubber and its products according to its constituent materials. Latex is a kind of Hedan Hall Xincheng rubber, which should be classified as 4016 "other products of vulcanized rubber (except hard rubber)". As a mold wheel type inflatable products, they are classified as other inflatable products".

Add up the 8 digits to get 25. Therefore, the correct answer to this question is 25 (.
