Read： 594 Time：12months ago Source：Transform the World with Simplicity

High resilience polyether is an important raw material widely used in the field of chemical production, especially in the field of soft furniture, car seats, packaging materials and other fields have a wide range of applications. This article will detail the manufacturing method of high resilience polyether.

1. manufacturing principle

high resilience polyether is made by polymerization. The polymerization principle is mainly through the ethylene oxide and polyol in the role of the catalyst under the addition polymerization reaction, to produce high molecular weight polyether. By adjusting the type of polyol, the amount of ethylene oxide and reaction conditions, high resilience polyether with different properties can be prepared.

2. Manufacturing Steps

1. Raw Material Preparation

The main raw materials for manufacturing high resilience polyether include polyol, ethylene oxide and catalyst. Glycerin, pentaerythritol and the like can be selected as the polyol, and ethylene oxide is in a gaseous state and needs to be introduced into the reactor using special equipment. The catalyst can be selected from basic catalysts, such as potassium hydroxide, sodium hydroxide, etc.

2. Feeding reaction

The polyol and catalyst are added into the reactor, and after heating to a certain temperature, ethylene oxide is introduced to carry out polymerization reaction. In order to ensure the smooth progress of the reaction, it is necessary to control the reaction temperature, pressure and the feed rate of ethylene oxide.

3. post-treatment

After the reaction, the product is post-treated, including neutralization, decolorization, filtration and other steps, in order to remove impurities such as catalyst and pigment, and obtain pure high-rebound polyether.
Precautions in the manufacturing process of

1. Control reaction conditions

In the process of manufacturing high resilience polyether, it is necessary to strictly control the reaction temperature, pressure and the feed rate of ethylene oxide to avoid the occurrence of side reactions and ensure the quality and performance of the product.

2. Prevent catalyst residue

catalyst residue will affect the quality and performance of the product, so the catalyst needs to be completely removed during the post-treatment process.

3. Ensure the safety and
of equipment The process of
manufacturing high resilience polyether involves high temperature, high pressure and other risk factors. Therefore, it is necessary to ensure the safety and reliability of the equipment and avoid safety accidents.

4. applications and market prospects

high resilience polyether as an important chemical raw material, widely used in upholstered furniture, car seats, packaging materials and other fields. With the continuous improvement of people's requirements for quality of life and comfort, the market demand for high resilience polyether is also increasing. At the same time, with the continuous progress and application of science and technology, the performance and application fields of high resilience polyether are also expanding, and the market prospect is broad.

5. conclusion The manufacturing method of

high resilience polyether involves the principle and manufacturing steps of polymerization reaction, and the reaction conditions and post-treatment process need to be strictly controlled to ensure the quality and performance of the product. At the same time, high resilience polyether has a wide range of application prospects and market demand in the field of chemical production, which is of great significance to improve people's quality of life and comfort.
