In modern society, as people’s requirements for quality of life improve, the demand for silent materials is also growing. Silent EVA Block, as an efficient sound insulation material, has been widely welcomed by the market due to its excellent silent performance and good processability. This article will introduce in detail the material selection, production process, production process, characteristics and application fields of the silent EVA Block, and explain it with the relevant parameter values.

　　1. Selection of silent EVA Block materials

　　The key to selecting silent EVA Block material lies in its sound insulation performance and stability. A high-quality silent EVA Block should have a high-density sound insulation layer that can effectively absorb and isolate sound and reduce the spread of noise. At the same time, the physical properties of the material such as hardness, wear resistance, impact resistance, etc. are also factors that need to be considered when selecting.

　　When choosing a silent EVA Block, you need to ensure that the selected material meets relevant industry standards and quality requirements to ensure its silent effect and durability in practical applications.

　　2. The production process of silent EVA Block

　　The production process of silent EVA Block mainly includes the steps of raw material preparation, adding silent agent, mixing, molding and post-processing.

　　In the raw material preparation stage, high-quality EVA raw materials and mute agents need to be selected. The type and amount of muting agent have a crucial impact on the muting performance, so precise proportioning and testing are required.

　　In the mixing stage, the EVA raw materials and the muting agent are fully mixed through professional mixing equipment to ensure that the muting agent is evenly distributed in the EVA.

　　In the molding and processing stage, the mixed silent EVA material is processed into the required shape and size through injection molding, extrusion and other processes. This process requires strict control of parameters such as temperature and pressure to ensure stable performance of the material.

　　The post-processing stage includes inspection and packaging of finished products to ensure that the quality and performance of the silent EVA Block meet the requirements.

　　3. Silent EVA Block production process

　　The production process of silent EVA Block is as follows:

　　Raw material preparation: Select EVA raw materials and mute agents that meet the requirements.

　　Mixing and stirring: Add the muting agent to the EVA raw material according to a certain proportion, and mix the two thoroughly through the stirring equipment.

　　Melting and molding: Heat the mixed silent EVA material to a molten state, and then process it into preset shapes and sizes through molding equipment.

　　Cooling and solidification: Cooling and solidification in the mold make the material reach the predetermined hardness and stability.

　　Inspection and packaging: Perform performance inspection on the silent EVA Block to ensure that it meets the silent performance requirements before packaging and warehousing.

　　4. Silent EVA Block Features

　　Silent EVA Block has the following notable features:

　　Excellent mute performance: By adding mute agent, the material has good sound insulation effect and can effectively reduce the spread of noise.

　　Good physical properties: Silent EVA Block retains the original excellent physical properties of EVA, such as hardness, wear resistance, impact resistance, etc.

　　Easy to process: It has good plasticity and processability, and can meet the needs of different shapes and sizes.

　　Safety and environmental protection: The selection and use of mute agents comply with environmental standards and will not cause harm to the human body or the environment.

　　5. Silent EVA Block application fields

　　Silent EVA Block is widely used in the following fields due to its excellent silent performance and good processability:

　　Construction industry: used in building materials such as floors and wall panels to improve the sound insulation performance of buildings and improve the living and working environment.

　　Transportation: Interior materials and sound insulation components used in vehicles such as cars and trains to reduce the impact of noise on passengers.

　　Electronic products: Used for sound insulation treatment of computers, audio and other equipment to improve the user experience.

　　Household products: Used to make household products such as soundproof mats and soundproof panels to reduce the interference of household noise on daily life.

　　6. Introduction to related parameter values of silent EVA Block

　　The following are some key parameter values of the silent EVA Block, which can be used as a reference for selection and use:

　　Sound insulation effect: Usually a higher sound insulation level can be achieved, and the specific value varies according to factors such as material thickness, density and type of mute agent.

　　Density: According to application requirements, the density of Silent EVA Block can be adjusted within a certain range to achieve the best sound insulation effect.

　　Hardness: Shore hardness can be selected within a certain range according to specific application scenarios to meet different usage needs.

　　Wear resistance: After special treatment, the silent EVA Block has good wear resistance and can maintain stable performance for a long time.

　　These parameter values can be adjusted and optimized according to specific needs to meet the requirements of different application scenarios.

　　In summary, silent EVA Block, as an efficient sound insulation material, has broad application prospects in the construction industry, transportation, electronic products, and household products. By rationally selecting materials, optimizing production processes and processes, and strictly controlling relevant parameter values, silent EVA Block products with stable performance, safety and environmental protection can be produced, providing strong support for improving people’s living environment.
