What are the processes for the configuration of raw materials for rubber parts? Many people ask how the rubber molding is like? The aging phenomenon of rubber is also asked by many customers. Next, rubber parts manufacturers will talk about these three questions!

The preparation of rubber raw materials can be divided into three basic processes:

1. Plasticizing: Plasticizing is to cut the raw rubber, plasticize and homogenize the raw rubber, and help the mixing operation of the compounding agent. The effect is to improve the dispersion of the medicine, prevent the frictional heat generated during the operation, and cause the scorch of the rubber, thereby changing the processability of the rubber.

2. Kneading: Kneading is to evenly mix the compounded drug into the raw rubber completed by mastication, and the quality of mixing directly affects the quality of the product. The drug is unevenly dispersed, the molecular structure cannot be completely cross-linked, and the rubber cannot achieve the desired physical properties.

3. Extrusion: After mixing the raw rubber, the excess air contained in the rubber compound will be extruded through the extrusion operation, and the required thickness will be completed, so as to facilitate the molding operation in the mold.

Molding of rubber:

The molecular structure of raw rubber is an elastomer with unsaturated long bonds, so in the molding elements, there must be appropriate drug additives and external environmental factors (such as time, temperature, pressure, etc.) Combined as a saturated bond and with the aid of a vacuum, the contained air was completely forced out. Only in this way can the molded rubber exert its proper characteristics. If there are any defects in the molding process (such as wrong formula, insufficient time, improper temperature, etc.), it can cause loss of physical properties, release of excess drugs, deformation, accelerated aging, and various serious adverse phenomena.

The rubber accessories manufacturer will introduce the aging phenomenon of rubber to you:

According to the environmental conditions of the rubber products, with the passage of time, the phenomenon of cracking or hardening, and the deterioration of the physical properties of the rubber is caused, which is called the aging phenomenon. The causes of aging include external factors and internal factors:

1. External factors: External factors include oxygen, oxides, ozone, heat, light, radiation, mechanical fatigue, lack of processing, etc.

2. Internal factors: Internal factors include the type of rubber, the molding method, the degree of bonding, the type of compounded drugs, and the factors in processing engineering.

To prevent the aging phenomenon, focus on the correct selection of rubber species and formula design, plus a rigorous production concept. Only in this way can the lifespan of rubber products be increased and the special functions they should have.

The most common problem of rubber is aging. Sidi Rubber Electronics adopts imported raw materials and non-toxic and non-polluting additives.
