Precautions for storing rubber hose

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…

Introduction to rubber vulcanization

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…

Rubber molding properties

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.…

Reasons and protection of rubber aging

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…

Change in the process of aging of the rubber

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…

Differences between teflon and stainless metal hose

Is Teflon tube different from stainless steel metal hose? Teflon and metal hose are often mistaken for the same material because of there are many features in common, such as: high temperature, corrosion resistance, wear resistance. And in the electrical, chemical, mechanical, metal surface treatment, pharmaceutical, medical, food, metallurgical smelting and other industries are widely…
