How to improve the tensile strength and elongation of rubber products

Improve the tensile strength and elongation of rubber products, high tensile strength formulations using natural rubber products, neoprene products, chlorinated yellowing polyethylene rubber products and other crystalline rubber. The rate of rubber content can reach 60% to about. In addition, the use of excellent reinforcing filler such as carbon black, silica and make it evenly dispersed.

What drilling tools are available and the function of the drilling tools

Drilling tools There are mainly wellhead tools and downhole drilling tools. Wellhead tools are tools for lifting and unloading drilling tools, such as lifting pliers, lifting clamps, tiles, etc. Lifting pliers are used for loading and unloading all kinds of downhole drilling tools. Lifting card is used to hang, lift and lower the drilling column. The chuck is used to hold the drill column and hang it on the turntable.

What are the categories of rubber seals? What are the roles of seals?

Rubber seal is a ring-shaped cover composed of one or several parts, fixed in the bearing of a ring or gasket and in another set of ring or gasket contact or form a narrow labyrinth gap to prevent the leakage of lubricating oil and foreign objects invasion.

Ozone aging and protection of rubber products

The activation energy of the reaction between ozone and unsaturated rubber is very low, and the reaction is easy to carry out until the double bond of the rubber is consumed, at which time a silver-white film of loss of elasticity is generated on the surface of the rubber, and as long as there is no external force to crack the film, the rubber will not continue to be ozonated.

The coupling depends on what the two shafts of the reducer are connected to

To see what type of equipment is connected to the two shafts of the reducer, coupling reducer selection coupling is the main consideration of the required transmission shaft speed of high and low load size, the installation progress of the two parts connected, the smoothness of rotation, price, etc., and according to the characteristics of various types of couplings, choose a suitable coupling type.

Couplings change rotational inertia to avoid resonance

Coupling in the work, the periodic load is a more typical form of load in mechanical transmission, the coupling cycle load change frequency and the transmission shaft system to stagger the inherent frequency. Generally by changing the inherent frequency of the shaft system to achieve the purpose of not resonating, and change the inherent frequency of the shaft system is generally to change the rotational inertia or stiffness of the shaft system, the rotational inertia and mechanical structure related to
