1. The rubber tube is stored in a relaxed state as much as possible. Generally, the hose with an inner diameter of 76 mm or less can be stored in a coil. 2. During the storage of the rubber tube, it is strictly forbidden to stack heavy objects on the pipe body and prevent external…
Under heating conditions, the raw rubber in the rubber compound reacts with the sulfide, and the crosslinking process of the macromolecule of the rubber from a linear structure to a three-dimensional network is called vulcanization. The vulcanized rubber is called cooked rubber. After vulcanization, the physical, mechanical properties and other properties of the rubber compound…
1. Molecular structure of rubber: Rubber is also a polymer compound with a relative molecular mass of several hundred thousand. The molecular size of the polymer compound is not fixed, and the so-called relative molecular mass refers to its average relative molecular mass. The relative molecular mass has a great influence on the rubber strength.…
Cooling water pipe. For irrigation, gardening, construction, fire, equipment and tanker cleaning, agricultural fertilizers, manure, industrial wastewater drainage and so on. Insulating material to PVC, EPDM majority. Made up of natural rubber , some specific hose with steel wire skeleton, high pressure, abrasion resistant, oil resistant , weather resistant . Picture: Steel wire spiral skeleton…
Rubber hose classification – 2. Hot water and steam hose High pressure steam pipe hot water and steam hose. Used for cooling equipment, cooling water, engine hot and cold water, food processing, especially dairy products, hot water and saturated steam. Insulating material to EPDM mostly. High temperature resistant , made up of rubber material with…
Rubber aging reasons: 1. Internal causes: The molecular structure of the rubber Chemical structure (or chain structure): The basic structure of rubber such as natural rubber unit isoprene, there are double bonds and active hydrogen atoms, so easy to participate in the reaction. Molecular chain structure: rubber macromolecular chain weak bond, the weak part of…
Rubber aging refers to the rubber or rubber products in the processing, storage and use of the process, due to a variety of external factors, and gradually lost the original excellent performance, resulting in the final loss of the use value. The aging process is an irreversible chemical reaction, accompanied by changes in appearance, structure…
