Misconception One: The higher the titanium content in titanium dioxide, the higher the whiteness?
Truth: Whiteness is a comprehensive indicator, not determined solely by titanium content.
Titanium content is one of the influencing factors, but impurity control, particle size, and surface treatment are equally crucial. Titanium dioxide achieves higher whiteness and coverage efficiency in downstream application scenarios through different refined process controls based on reasonable titanium content, avoiding cost waste caused by blindly pursuing high content.
Misconception 2: Does titanium dioxide make paper fragile and reduce paper quality?
Truth: Paper strength is influenced by multiple factors, not just titanium dioxide.
Because using White Powder Titanium Dioxide as a filler will occupy the fiber bonding space, which to some extent affects the strength of the paper, but other factors such as the dispersion uniformity of the filler, fiber state, and drying process have a more significant impact. Therefore, the key lies in selecting titanium dioxide with good dispersibility, controlling the addition amount reasonably, and matching suitable processes, so as to improve the optical properties of the paper while maintaining its physical strength and toughness, and achieve the optimization of comprehensive quality.
Misconception 3: Will titanium dioxide react with the components in paper to produce harmful substances?
Truth: Titanium dioxide has stable chemical properties, and its safety depends on purity and compliance.
Titanium Dioxide Pigment has extremely stable and inert chemical properties, and will not undergo harmful chemical reactions with cellulose, other fillers, chemical additives, etc. in paper. The key is to select high-quality titanium dioxide that meets relevant safety regulations and ensure that its application process complies with specifications. Titanium dioxide strictly adheres to product safety and compliance standards, never introduces harmful substances, and can be safely used in the production of various paper products.
Misconception 4: The more titanium dioxide used, the higher the opacity?
Truth: There is indeed an increase, but it follows a diminishing marginal effect.
Initial addition can significantly improve opacity, but excessive addition slows down the effect growth, increases costs, and affects paper performance. Within a reasonable range of additions, we help customers achieve their target opacity with low usage through the high coverage of our products, achieving cost reduction and efficiency improvement.
Misconception 5: Can titanium dioxide cause decorative paper to turn gray after being pressed and exposed?
Truth: High quality titanium dioxide is actually the key to anti graying.
The paper exposure gray change is closely related to the dispersion uniformity, impurity content, and surface treatment of titanium dioxide. Adding high-quality, well surface treated (such as inorganic and organic coating) rutile titanium dioxide not only does not cause the decorative base paper to turn gray after being pressed and exposed, but is also a key component in resisting gray transformation, ensuring paper whiteness and coverage. Titanium dioxide BLR-852 adopts rutile crystal structure and special coating process, with good dispersibility, low impurities, high retention rate, and high blue wool index, which can effectively maintain paper whiteness and cover stability, avoiding the phenomenon of gray transformation after the original paper is pressed and exposed.
Summary: Choosing the right titanium dioxide results in better paper quality
In the papermaking process, there is no "unique standard", only the "most suitable combination".
