The internal release agent of water-soluble resin is a special additive that plays a key role in water-soluble resin to ensure that the product can be smoothly demoulded during processing while maintaining the integrity and surface quality of the product.
First, internal release agents work by reducing the adhesion between the water-soluble resin and the mold surface. During processing, when the resin comes into contact with the mold surface, the internal release agent will form a lubricating film between the two, reducing the direct contact between the resin and the mold, thereby reducing the adhesion. This allows the product to be released from the mold more easily after cooling and solidification, reducing resistance and friction during demoulding.
Secondly, internal release agents can also improve the processing properties of water-soluble resins. It can reduce the viscosity of the resin and improve its fluidity, making it easier for the resin to fill the details of the mold during processing and reducing the occurrence of defects such as bubbles and shrinkage cavities. At the same time, the internal release agent can also help adjust the curing speed of the resin to ensure that the product has sufficient strength and hardness after demoulding.
In addition, internal release agents can also improve the surface quality of water-soluble resin products. It can reduce defects and blemishes on the surface of the product, such as cracks, scratches and bubbles, making the surface of the product smoother and more beautiful.
In short, the internal release agent of water-soluble resin plays an important role in the processing of water-soluble resin by reducing adhesion, improving processing performance and improving surface quality, ensuring that the product can be demoulded smoothly and a good finished product can be obtained. quality.
