观色，即仔细观察耐酸碱橡胶软接头的颜色，很多冒牌货由于采用的是低端、质量次的橡胶，所以生产出来的球体颜色往往特别灰暗，为了避免有经验者一眼识破。 Introduction: Look at the color, that is, carefully observe the color of acid and alkali resistant soft joints. Many counterfeit goods are made of low-end, low-quality rubber, so the color of the spheres produced is often very dark. In order to avoid those who are experienced at a glance.
As market competition intensifies, some small acid and alkali resistant rubber soft joint
manufacturers often use acid and alkali resistant rubber in the inner rubber layer of the sphere in the production process in order to reduce costs, while the skeleton layer and outer rubber layer still use ordinary rubber. What's more, only real rubber is used on the layer passing through the medium. How to ensure the quality and performance of this type of acid and alkali resistant soft joints, I would like to remind our customers in Shanghai to buy acid and alkali resistant rubber. When the flexible joint is used, it must be purchased from a large manufacturer to ensure the quality.
Observe the color, that is, carefully observe the color of the acid- and alkali-resistant rubber soft joints. Because many counterfeit goods use low-end, low-quality rubber, the colors of the spheres produced are often very dark. Most of them will polish and polish the black shoe polish before leaving the factory to make it look black and shiny. However, the soft acid-resistant rubber joints produced by genuine acid-resistant rubber have a pure color and a slight fading. Not very bright or very dark.
Taste is actually the best way to judge. Because rubber contains olefins, rubber has a pungent smell that normal people feel. But acid- and alkali-resistant rubber is a polymer of ethylene and propylene, and is a highly filled material. Therefore, the acid- and alkali-resistant rubber after vulcanization and filling does not have the pungent smell of ordinary rubber, but replaces an aromatic the taste of. So as long as users pay attention, it is not difficult to judge the real good.
The touch, that is, you carefully rub the inner layer of the rubber ball, you will have a smooth feel, because the authentic acid and alkali resistant rubber is excellent in texture and expensive. Therefore, the soft acid-resistant rubber joints produced are particularly smooth to the touch, while ordinary rubber feels much worse to the touch, and it will feel the touch of rough skin.
