Active zinc oxide

没有此类产品
Description

  Application in the rubber industry

  It can be used as a functional additive such as a vulcanization activator to improve the performance of rubber products such as smoothness, wear resistance, mechanical strength and anti-aging performance, reduce the use of ordinary zinc oxide, and prolong the service life.

  Application in the ceramic industry

  As a enamel glaze and flux, it has excellent performance in reducing sintering temperature, gloss and flexibility.

  Application in the defense industry

  Active zinc oxide has a strong ability to absorb infrared rays, and has a large ratio of absorption rate to heat capacity. It can be applied to infrared detectors and infrared sensors. Active zinc oxide also has the characteristics of light weight, light color and strong absorbing ability. Effectively absorb radar waves and attenuate them for use in new types of absorbing stealth materials;

  Application in the textile industry

  It has good UV shielding property and superior antibacterial and antibacterial properties. It can be added into fabrics to impart functions such as sun protection, antibacterial and deodorization.

  Application in the feed industry

  As a nano-material, active zinc oxide has the characteristics of high biological activity, high absorption rate, strong anti-oxidation ability, safety and stability, and is currently the most ideal zinc source. Replacing high zinc with active zinc oxide in feed can not only solve the zinc demand of the animal body, but also reduce the pollution to the environment. The use of active zinc oxide can play the role of antibacterial and antibacterial, while improving animal performance;

  Applications in coatings, cosmetics and other applications

  Metal oxide powders such as zinc oxide, titanium dioxide, silicon dioxide, aluminum oxide, magnesium oxide, etc., when these powders are made into nanometer scale, the size of the particles is equivalent to or smaller than the light wave, and the conduction band is caused by the size effect. As the interval between the valence bands increases, the light absorption is significantly enhanced. Various powders have different differences in light shielding and reflection efficiency. When zinc oxide and titanium dioxide are compared, when the wavelength is less than 350 nm (UVB), the shielding efficiency is similar, but at 350-400 nm (UVA), the shielding efficiency of zinc oxide is significantly higher than that of titanium dioxide. At the same time, the refractive index of zinc oxide (n=1.9) is smaller than that of titanium dioxide (n=2.6), and the diffuse reflectance to light is low, which makes the fiber transparent and facilitates dyeing and finishing of textiles.

  Active zinc oxide can also be used to make materials for far-infrared reflective fibers, commonly known as far-infrared ceramic powder. The far-infrared reflective functional fiber absorbs the heat emitted by the human body and radiates far-infrared rays of a certain wavelength range to the human body, in addition to increasing the blood flow in the subcutaneous tissue of the human body, promoting blood circulation, and shielding infrared rays. The heat loss is reduced, so the fiber is more thermally insulated than the general fiber.
