Common raw materials for making correction fluids

The correction fluid, also known as the correction fluid, is a common stationery item used to modify the wrong text in the daily learning environment of students. Although many different types of raw materials can be used as correction fluids, common correction fluid raw materials are opacifiers, polymer film formers, solvents, and the like.

The clouding agent (also known as clouding agent, opacifier, and turbidity agent) is also the emulsion stabilizer we often say. The opacifier is a key formulation of the correction fluid, which can cover the wrong effect. The most common opacifier is titanium dioxide, which is derived from a variety of titanium ores, which is an opaque material that does not significantly absorb visible light. Different colors can be formulated by processing or mixing titanium dioxide of different materials. Generally, the white correction solution contains 40-60% of titanium dioxide.

The opacifier can be covered on the paper with the wrong content. When the liquid is dry, the opacifier forms a paper film which can be firmly adsorbed on the paper. The paper film is not easy to crack and break. A wide variety of polymer resins are used in, for example, acrylic resins, petroleum resins, chlorinated polyolefin resins, and even synthetic rubbers. This polymer produces the best correction fluid overlay film, typically 5-15% in the formulation.

Controlling viscosity and drying time is a very important condition for making correction fluid. Generally speaking, the correction fluid is made thinner to make it more even and stable during use. The solvent acts as a diluent and a fast evaporation. In addition, the solvent improves the stability of the correction fluid, making it more compatible with other materials. The solvent for the correction fluid must be carefully selected. On the one hand, it needs to evaporate quickly to facilitate fast writing. On the other hand, it cannot evaporate too quickly and solidify in the bottle so that it does not come out.

There are a variety of different ingredients in the correction fluid to stabilize or optimize the performance of the correction fluid, and even some materials can cause unpleasant odors. This is also really criticized by the vast majority of consumers, but it is undeniable that the correction fluid is indeed able to provide great help to consumers. With the gradual development of the stationery industry, the correction tape is increasingly popular with consumers because it can replace the correction fluid without producing an unpleasant smell.
