Performance Magic
Coating - grade calcined talc works wonders for the performance of coatings. It significantly improves the suspension property of coatings. When coatings are stored, you want all their components to stay evenly distributed. With calcined talc, you can bid farewell to concerns about precipitation and stratification. This ensures the stability and uniformity of
coatings, like a reliable guardian maintaining order in the coating system.
At the same time, it boosts the dispersibility of coatings. Pigments and other particles can be more easily dispersed in the coating system. This leads to more uniform and saturated colors, making your coatings look more vibrant and attractive.
Tough Protection
The physical properties of coatings get a major upgrade with calcined talc. It enhances the wear resistance of coatings, giving them stronger armor against wear and tear. This means your coatings will have a longer service life, able to withstand the test of time and frequent use.
Moreover, it increases the corrosion resistance of coatings. In the battle against external corrosive media, calcined talc acts as a shield, providing coatings with a certain degree of protection and prolonging their lifespan.
Perfect Flow Control
When it comes to rheological property regulation of coatings, calcined talc powder is a great helper. It plays a thickening role, allowing you to adjust the viscosity of coatings with ease. During the construction process, this ensures coatings have excellent leveling and application performance. Say no to run - off or orange - peel - like phenomena after drying. Your coatings will have a smooth and even finish, just as you desire.
Beautifying and Function Boosting
In decorative coatings, calcined talc is like a beautician. It enhances the gloss and smoothness of coatings, giving them a delicate and smooth appearance that catches the eye. And in functional coatings such as fire - proof and thermal - ones insulation, it works in synergy to improve the comprehensive performance of coatings. It is truly an important functional filler in coating production.
Stunning Visual Effects
The optical performance of coatings is also improved by calcined talc. It increases the glossiness of coatings, making their surfaces smoother and more uniform. This creates a visually pleasing effect that can attract everyone's attention. Additionally, it helps reduce the oil absorption of coatings and improves pigment dispersion. As a result, colors become more vivid and pure, bringing your coatings to life.
Cost - Effective Choice
Another advantage of calcined talc is its relatively low price. Without compromising the performance of coatings, it can partially replace some expensive raw materials. This effectively reduces the production cost of coatings, giving your products a competitive edge in the market. Furthermore, it improves the fluidity and leveling of coatings, making them easier to apply evenly during construction. This reduces defects like streaks and ensures better application results, saving time and effort.
Manufacturing Technique
1. Raw material preparation: The raw material for the production of calcined talc powder is mainly natural talc ore, which needs to be preliminary processed, cleaned and selected. First of all, the talc ore is crushed, crushed and other preliminary processing, and then the ore is cleaned to remove impurities, and finally selected to screen out the ore that meets the requirements.
2. Calcination process: The ore after raw material preparation needs to be calcined in order to obtain calcined talc powder. Calcination temperature and time are important factors affecting the quality of calcination, usually calcination temperature between 800ºC-1200ºC, the time is determined according to the temperature, generally takes 2 to 6 hours. In the process of calcination, attention should be paid to the sealing property of calcination furnace and the control of calcination atmosphere.
3. Crushing and screening: the calcined talc ore needs to be crushed and screened to obtain talc powder with appropriate particle size. Under normal circumstances, the use of a grinder for crushing, and then the use of a screening machine for screening, to obtain talc that meets the requirements.
4. Packaging and storage: The talc powder after grinding and screening needs to be packaged and stored. Plastic bags are generally used for packaging, and the net weight of each bag is about 25kg. During the storage process, it is necessary to avoid direct sunlight, humidity, and high temperature, and to prevent mixing with other chemical substances.
