Wanquan compensator teaches everyone three strokes to distinguish the quality of EPDM rubber joints and true and false

Basic engineering construction for water supply, drainage, sewage treatment, electricity, metallurgy, petrochemical, urban construction, environmental protection, etc.


In recent years, with the increasing progress in the production technology and process of rubber joints, the accompanying fakes and defective products have been unknowingly mixed into the market, so that the majority of customers are also helpless in choosing a regular product. Especially high temperature, oil, acid and alkali resistant EPDM rubber soft connectors.
EPDM (Ethylene-Propylene Diene Rubber) is characterized by ozone resistance, UV resistance, weather resistance and aging resistance, ranking first in general rubber. Its use temperature is about -50 °C ~ +150 °C. Gongyi Wanquan Plant achieves optimal performance through high filling of EPDM rubber and can be applied to work under high compound conditions. Example: Acid and alkali resistance, high temperature resistance, and aging corrosion. So its price is high.
However, on the current EPDM joints on the market, it is common for small manufacturers to use ethylene propylene diene monomer in the inner rubber layer of the spheres in the production process to reduce costs. The skeleton layer and the outer rubber layer Ordinary rubber is still used, and even worse, real rubber is only used on the layer that passes through the media. From this we know that the life of such rubber joints is guaranteed. Gongyi Wanquan Pipeline Equipment Factory--Henan Provincial Contract-honoring and Promise-keeping Enterprise Today, Gongyi Wanquan Pipeline Equipment Factory has summarized several points to judge authentic EPDM rubber joints based on its own industry experience in this industry. The method, so that the majority of users know when the purchase of fire, "authenticity."
First, look at the color of the color, that is, carefully observe the color of the rubber sphere. Many counterfeit goods use low-end, quality rubber. Therefore, the color of the sphere produced is often particularly dark, in order to prevent experienced people from seeing it at a glance. Most of them will be oiled and polished with black shoe polish before leaving the factory, making it look dark and shiny. However, the rubber joints produced by the genuine EPDM rubber are pure in color and slightly faded. Not particularly bright or extremely dark.


Second, smelling the taste is actually one of the best methods to judge. Because the rubber contains ene, the rubber will have a pungent smell that normal people will feel. However, ethylene propylene diene monomer (EPDM) is an ethylene and propylene polymer, and it is a highly filled compound. Therefore, EPDM rubber after vulcanization does not have the pungent taste of ordinary rubber, but instead replaces it. A kind of aromatic taste. Therefore, as long as the user pays attention, it is not difficult to judge the real good goods.


Third, touch it, that is, you carefully friction the inner layer of the rubber ball, there will be a smooth feeling, because of the authentic texture of EPDM rubber is excellent, expensive. Therefore, the rubber joints produced are particularly smooth on the touch, while the ordinary rubbers have a poor touch feeling and may feel rough skin.
Gongyi Wanquan Pipeline Equipment Factory mainly produces flexible rubber joint series, stainless steel bellows compensator series, duct fabric compensator series, pipe expansion joint series products, single ball rubber joints, double ball rubber joints, different diameter rubber Joints, elbow rubber joints, and other products.
