The hometown of rubber is South America, and the local Indians call it the tears of the tree. Because the skin of the rubber tree is cut, white latex will flow out like a tree in tears. At first, people added a little acetic acid to the latex and condensed into a solid substance. This is raw rubber. The molecular structure of the raw rubber is a linear structure like a single chain, and the strength is not high. Although it is elastic, it is easy to break. Especially sensitive to changes in temperature, a heat will become soft and sticky, and a cold will become hard and brittle. In rubber processing plants, people began to use sulfur to revolutionize the appearance of raw rubber. The sulfur atom can connect the rubber molecules to each other, and the linear structure of the rubber molecules becomes a network structure, thereby greatly increasing the strength of the Goma. iti panagproseso ti goma, malaksid ti pannakainayon ti maysa a bulkanizing agent, maysa a pangkolor nga ahente, maysa a pangpalukneng nga ahente, maysa a mangpapigsa nga ahente, maysa a filler, maysa nga antioksidante, ken dagiti kapada ket mainayon..
The sun contains a lot of ultraviolet rays, and in addition to being able to sterilize and cure ultraviolet rays, it is also a "pecker." When it is drilled into the interior of the rubber product, the molecular chain of the rubber is cut. At the same time, the high heat of the sun will separate the sulfur atom from the raw rubber and destroy its molecular structure. As a result, the rubber loses its Ti kinalalaki ken ti intermolekula a singgalut, isu a nadadael ti bitak..
Gapuna, no lumabaska kadagiti overshoes ken sapatos a goma, bugguan a dagus, ikabilmo ida iti nasipnget ken nabentilasion a lugar a pagmagaen, saan nga ibutaktak ti init wenno iluto iti paglutuan, ken saan a sagiden ti kerosene ken gasolina, gapu ta lanaan dagiti molekula ti klase ket ma-drill kadagiti molekula ti goma, a mangpalawa kadagiti molekula ti goma ken pakaigapuan ti sapatos a goma nga agturong iti swell ken deporm{0}}}
