The visual appeal of fiberglass steps should not be underestimated
The use of corrosion-resistant FRP has been extensive in infrastructure, particularly in bridges, pipelines, and storage tanks. Its lightweight yet high-strength characteristics allow for easy installation and reduced maintenance costs. In the chemical industry, FRP is used for containment vessels, piping systems, and equipment, ensuring safe and efficient operation without the risk of material degradation In the chemical industry, FRP is used for containment vessels, piping systems, and equipment, ensuring safe and efficient operation without the risk of material degradation

It's also added directly to food; mainly for coloring, but also as a thickener and to keep some powdered food, like confectioner's sugar, from clumping.
- When the pH of titanium dioxide deviates from the optimal range, its properties and performance may be compromised. For example, at low pH levels (acidic conditions), titanium dioxide particles tend to agglomerate and form clusters, leading to poor dispersion and reduced whiteness. On the other hand, at high pH levels (alkaline conditions), the stability of titanium dioxide can be compromised, resulting in decreased opacity and color performance.
- Furthermore, we are dedicated to responsible sourcing and production practices. We work closely with our partners to ensure that our titanium dioxide is produced sustainably and ethically. By doing so, we not only contribute to the longevity of our industry but also minimize our impact on the environment.
- Growing use of Lithopone in the plastics processing industry
- Chemical products manufacturers are the unsung heroes of modern society, playing a crucial role in every aspect of our daily lives. From the soap we use to clean our hands to the fertilizers that help grow our food, these companies produce a vast array of chemicals that are essential for our well-being and comfort.
- It is white because it does not absorb visible light
Production
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
Uses
The FDA and certain others say titanium dioxide is safe to use in foods and personal care products. The FDA provides strict guidelines on how much can be used in food. The limit is very small: no more than 1% titanium dioxide.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.[1]
Preparation of Lithopone:
Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.
Looking ahead to 2023, titanium dioxide will play a key role in various industries. The growth potential of this chemical is huge, and companies like Hebei Caiqing Material Technology Co., Ltd. are well positioned to meet the changing demands of the market. With its individual customization services and dedication to research and development, the company is well-positioned to meet the growing demand and contribute to the advancement of titanium dioxide applications worldwide. Whether in coatings or plastics, titanium dioxide brings innovation, protection and improved product performance to a wide range of customers around the world.
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
