Zinc oxide is a compound of gender, through its alkaline and acid can be combined. In combination with low acid index, zinc oxide zinc produced soap, paint the increased wettability, so that is more easily dispersed, at the same time to paint and to reduce the viscosity of a slight increase of precipitation. In the high-acid index of the adhesive, the container will be extremely thickening.

Zinc oxide general overview: product traits: white powder, the density of 5.606, melting point of 1975 ℃ is a gender-oxide, do not dissolve in water or alcohol-soluble acid-base solution. Temperature when the yellow and white after cooling. Application: 1, Low coefficient of expansion for the ceramics with good heat out of action and mechanical vibration. 2, surface area, very good hiding power and strong resolve of feed at the end of the color of color on the surface of ceramic products. 3, less iron and other elements in the raw materials used Seyou, so that the ceramic products of small color difference
The main danger mark use of paint used for paint and rubber filler. On the system for medical ointment, zinc paste, plaster, etc.



The application of zinc oxide
      Zinc oxide rubber and tire industry is essential additives, also used for natural rubber, synthetic rubber and latex curing the active agent and reinforcing agent, as well as coloring agents. If the general made of zinc oxide nano-zinc oxide used in rubber, you can give full play to promote the curing effect in enhancing the performance of rubber, the amount of zinc oxide only general 30% to 50%. Zinc oxide surface area of research is very important, zinc oxide surface area BET testing data is only used to detect the result is a true and reliable, there are a lot of domestic equipment can only do a direct comparison method of detection, are also being eliminated. At present, domestic and specific surface area test unified multi-point BET method, at home and abroad to develop specific surface area measured by the standard testing methods are based on BET-based, reference is made to our national standards (GB / T 19587-2004) - gas adsorption BET principle Determination of solid material surface area. Detection of specific surface area is relatively time-consuming work, as the absorption capacity of the sample, some of the test samples may need to spend a full day, if the test did not achieve a fully automated process, and that testers can not leave on time and to A high degree of concentration, observation instrument panel, the control knob, a little inattentive when the testing process will lead to the failure of this test would be a waste of a lot of staff time. F-Sorb 2400 surface area analyzer is able to achieve real BET method of detection equipment (both direct contrast) and, more importantly, F-Sorb 2400 surface area analyzer is so far the only fully automated intelligent than the surface area of detection Equipment, the test results with the international high consistency, stability is also very good at the same time to reduce human error and improve the accuracy of test results.
     In the chemical industry, zinc oxide is widely used as a catalyst for desulfurization agent, such as methanol synthesis catalyst when, when ammonia desulfurization agent; nano-zinc oxide on the surface of highly active catalyst to increase the choice of catalyst performance and efficiency, with a wide range of potential Application of the market.
     In the coatings industry, with zinc oxide in addition to color and hiding power, is in the paint preservatives and light-emitting agent; In addition, ZnO excellent ultraviolet shielding its ability to paint in the anti-aging, and so has a more prominent Characteristics.
    In medicine and health food industry, with zinc oxide Sida, to stop bleeding, myogenic convergence of function, but also plaster for raw materials, but also for the promotion of children's mental development has helped; nano-zinc oxide used in health food industry's demand to gradually To expand, but the product requirements more stringent, particularly the harmful heavy metal elements.
    In the glass industry, zinc oxide used in specialty glass products; in the ceramic industry, zinc oxide used as a flux; in the printing and dyeing industry, zinc oxide used to prevent dye; nano-zinc oxide particles because of small, high-activity, Glass and ceramics to lower the sintering temperature, in addition to the use of the preparation of nano-zinc oxide ceramic glazed more bright and clean, and has anti-bacterial, anti-enzyme, such as the effectiveness of deodorant.
The role of zinc oxide added:
     In the electronics industry, zinc oxide varistor is the main raw material is also magnetic, optical materials such as the main additive. Preparation of the use of nano-zinc oxide varistor, not only has a lower sintering temperature, and pressure-sensitive resistors to improve performance, such as the ability to flow, such as coefficient nonlinear. Nano-zinc oxide in optical devices in the application of the optical properties of nano-zinc oxide as an in-depth study will be more breakthroughs.
Zinc oxide is a white or yellow microstrip fine powder, easily dispersed in rubber and latex, natural rubber, synthetic rubber reinforcing agent, curing agents and agent activity, but also the white rubber filler and coloring agent. Rubber activity by adding zinc oxide, rubber can have good wear resistance, tear-resistant and flexible. For the paint, ink, rendering the varnished cloth, printing and dyeing industry of anti-dye printing, in the match industry and the glue used in the acid to increase the effectiveness of glue, adhesive plaster used in the pharmaceutical industry's raw materials, as well as for Zinc chrome yellow paint, zinc acetate, zinc carbonate, zinc chloride, such as the manufacture of synthetic methanol as a catalyst, the ammonia desulfurization agent, glaze and glass production, fine particles of zinc oxide activity (diameter of around 0.1um) can be used Polyolefin and PVC plastic, such as optical stabilizer, zinc oxide is also used to pressure-sensitive, photocatalytic, photovoltaic very, paint, color imaging and other fields.
     Zinc oxide for white paint. As the activity of zinc oxide has a good performance activated in the rubber has been more widely used, such as the V-belt can not only replace the equivalent of an ordinary zinc oxide, and can reduce the 1/2-1/3 Amount, so that the rubber of a variety of performance and stability, curing properties will not be affected, reducing production costs. The fine zinc oxide can be used as pharmaceuticals. Zinc oxide as a result of UV absorption capability, there is growing emphasis on zinc oxide in the application of cosmetics, such as the development of the 0.01-0.04um size of the particles of zinc oxide, the UV absorption rate than that of transparency has been used in titanium dioxide particles.
      Transparent zinc oxide coating can be done to effectively prevent discoloration coating. In addition to zinc oxide such as cosmetics, but also can be used as car paint, furniture, building materials, ink, paint raw materials, can also be used for rubber, plastic Anti-aging agent. The recent development of transparent food packaging film is transparent zinc oxide in the coating of polyethylene film, plastic film will help enhance the ability of anti-ultraviolet radiation, but also to protect the quality of the food. With the high-tech development, it is being developed as the use of metal, ceramic materials, the reinforcement of zinc oxide whiskers and ceramic materials, plastics film filtration materials, gas sensors, electromagnetic shielding materials and a large majority of the surface area of zinc oxide materials
