Among all Weas' inventions, the most famous is the plastic soda bottle. In modern society, beverage bottles made of plastic are so common that people do not realize that they have any special place at all. However, the products that are now commonplace were very strange at that time, and even a bit of weird ideas. People usually say: "Plastic bottles can not be carbonated drinks, or it will be broken." Weiss does not believe this. So he tried to do the experiments at home, but he found that the results were indeed what people said. Plastic bottles are so thin that they do not withstand much pressure. Different from others, Weiss did not give up the idea of ​​using plastic to make beverage bottles.
Wess started researching plastics. He found that when casting plastic objects with a mold, some parts of the plastic should appear solid; if injection molding is used, that is to melt. This article comes from the plastic injection molding mold made of China's largest plastic bottle trading website. This situation is even more obvious. As a result, Weiss began to think: Why can't we get the overall strength evenly? If this assumption can be achieved, plastics that are cheap, light, and strong enough can be made out of less plastic.
While thinking and researching individually, Weiss fully noted the work of nylon inventor Carothers on nylon. As Wess said, "Invention is not an art of loneliness." Communication with others leads to "certain hints that break some of the illusions of long-cherishing thoughts ... that can help and help you do what Franklin says" to avoid sticking to rules. "'. In the same way, Carothers' work has also lightened the direction of the study for Weiss.
When Carloss studied nylon, it was found that stretching the fibers during the production process allowed the molecules to be regularly arranged to make the product more robust because the molecules were arranged in the direction of stretching. This inspires Weiss, who can stretch a plastic bottle and align its molecules in one direction to obtain a product of sufficient strength to hold a carbonated beverage.
However, the work Wys wants to do is more complicated than it thinks, because in the fiber, it is only necessary to align the molecules in one direction to obtain a product with sufficient strength; and to obtain a uniform plastic bottle, it must be simultaneously Consider the circumferential and axial arrangement.
Wess started to experiment according to his own ideas, but not everyone understood Weis' ideas and work. When Weas first told colleagues about his idea of ​​designing stretch plastic bottles, some of them told him that he was "wasting time." Wess was not frustrated. Instead, he found that those who opposed him gave him more incentives. In the early years of making the first toy, Weiss learned to use the negative reaction as the driving force for advancement. At that time, my father always praised his son's work with sincerity, pointed out the flaws very gently, and made Wei Si understand his own deficiencies.
Wess tried his own hard tests again and again. At the beginning, the bottle always breaks when stretched. After numerous observations, he finally found that only by pressing the bottle in the direction of the cross stream can it increase its strength without breaking. After replacing the original polypropylene with a more elastic material polyethylene, Weiss finally made a strong and beautiful plastic soda bottle. Now, this product is being produced from factories around the world at a rate of millions per day.
