Engatto zaffe ezisukkulumye n’engatto za kapiira zijja kwambala nnyo era zifuuke nga zikutuse era nga nnyangu okukutula. ekintu kino kiyitibwa okukaddiwa kwa kapiira. Okukaddiwa kwa kapiira kizibu kizibu nnyo. okutwaliza awamu, okufuula omukka, omusana n’ebbugumu eringi bisobola okuleeta omupiira okukaddiwa.
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 wa kapiira. mu kukola kapiira, nga kwotadde n’okugattako ekirungo ekikuba envubu, ekirungo ekikuba langi, ekirungo ekigonza, ekirungo ekinyweza, ekijjuza, ekiziyiza obuwuka obuleeta obulwadde, n’ebirala ebiringa ebyo byongerwako.
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 Elasticity ne intermolecular bond, kale enjatika eyonoonebwa.
Therefore, when you pass the overshoes and rubber shoes, wash them immediately, put them in a dark and ventilated place to dry, do not expose to the sun or bake at the stove, and do not touch kerosene and gasoline, because oil The molecules of the class will be drilled into the rubber molecules, which will expand the rubber molecules and cause the rubber shoes to swell and deform.
