Talcum powder mixed in floor coating is a silicate mineral belonging to the talc group, mainly composed of hydrated magnesium silicate (Mg3Si4O102), which is produced through processes such as crushing, hydrochloric acid treatment, water washing, and drying.
The role of talcum powder mixed in floor coating mainly includes the following aspects:
Cost reduction:
Talc powder has a relatively low price, and adding it to epoxy floor paint can significantly reduce material costs.
Increasing the amount of filler added:
Talc powder can increase the amount of filler added without significantly increasing the viscosity of the coating, ensuring the leveling of the coating during construction.
Improving construction performance:
Talc powder has good fluidity and can improve the leveling of coatings, ensuring uniformity and flatness during construction.
Reduce volume shrinkage rate:
The sheet-like geometric structure of talc powder can significantly reduce the linear shrinkage rate of the coating and improve the stability of the coating.
Improving wear resistance and chemical resistance:
Talc powder contains silicon dioxide, which can enhance the wear resistance and chemical resistance of coatings.
Improving mechanical strength and volume resistivity:
Adding talc powder to epoxy resin sealant can enhance its adhesive strength, mechanical strength, volume resistivity, and heat resistance.
Improving comprehensive performance:
The chemical properties of talc powder are stable and do not affect the chemical resistance and other comprehensive properties of the coating film.
Easy to color matching:
Talc powder has high whiteness, is easy to match, and has a high overall cost-effectiveness.
In summary, the application of talcum powder mixed in floor paint coating not only reduces costs, but also significantly improves the construction performance, physical properties, and chemical stability of the coating.
