Coloured silicone sheet is a kind of silicone sheet with special colours, which is widely used in printing, advertising, decoration, handicrafts and other fields. The production of coloured silicone sheets is achieved by adding pigments or dyes to the silicone, and different pigments or dyes can produce a variety of coloured silicone sheets. The following is an introduction to the production of coloured silicone sheets and the method of colouring.
Production of coloured silicone sheets
The production of coloured silicone sheet is mainly divided into the following steps:
1. silica gel raw materials preparation: first of all, you need to prepare the silica gel raw materials, the quality of silica gel raw materials and the quality of silica gel sheet is closely related, so we need to choose high-quality silica gel raw materials.
2. Processing: Silicone raw materials into the processing machine for processing, processing should be based on different uses and requirements to choose a different processing technology.
3. Adding coloring agent: coloring agent is one of the main components of coloured silica gel sheet, the choice of coloring agent has a great impact on the quality and colour of silica gel sheet. Different colouring agents should be selected according to different requirements.
4. Mixing: Mix the colouring agent with the raw material of silica gel, and make the colouring agent evenly distributed in the silica gel by stirring or other methods.
5. Forming: Put the mixed silica gel into moulds to form, and make it solidify and form by heating or other methods.
6. Processing: After moulding, the silicone sheet needs to undergo subsequent processing techniques, such as cutting, engraving, printing, etc., to meet different needs.
Colouring method of coloured silicone sheet
1. Mechanical mixing method: add the colouring agent to the silica gel raw material, disperse the colouring agent evenly in the process of mechanical mixing, and then carry out the moulding.
2. static mixing method: put the colouring agent and silica gel raw materials into the moulding machine at the same time, make the colouring agent evenly distributed by mixing in the static state, and then carry out moulding.
3. Spray colouring method: the colouring agent is evenly sprayed on the surface of the silicone sheet through a sprayer, and then moulded.
All the above three methods can be used for colouring the coloured silicone sheet, choose the appropriate method according to different needs and requirements.
Summary
The production of coloured silicone sheet and the colouring method is a complicated process, which requires different raw materials and processes to be selected according to different requirements and demands. Therefore, it is necessary to pay attention to quality management and implement strict production standards during the production process in order to produce high-quality coloured silicone sheets. Through continuous R&D and innovation, the application fields of coloured silicone sheet will be more extensive, bringing more convenience and innovation to our life and work.
