 Damp process active Zinc oxide
The company adopts Taiwan wet method new technics. The product gets obvious performance cost advantages.
Features:
Inorganic compound zinc oxide is hard to disperse in rubber, plastic, paint and other industrial products. The activity of zinc oxide, because of its small size, large surface area has a good affinity with the organic compounds, it is easier to evenly scattered, hence in rubber and other related industry is both a good performance distributed activator, also enhanced rubber Thermal conductivity and other products, the best heat transfer agent, be received Yijianshuangdiao achievements.
Activated zinc oxide is 1.5-3 larger than inorganic zinc oxide for PH value.
To maintain acid-base balance of rubber to prevent the phenomenon of spit cream.
Reduce toxic substances and the first optional additive for transparent and semi-transparent rubber, paint, electronic, pharmaceutical, daily chemical and other industries.
Reduce dosage and production cost and increase product grade
Modern Applications and prospect
Chemical Industry: Zinc oxide is widely used as a catalyst, desulfurization agent, such as synthetic methanol as the catalyst, when ammonia desulfurization agent; the surface of zinc oxide catalysts with high activity can increase the choice of performance and efficiency, with a wide range of potential applications.
Coatings Industry: In addition to zinc oxide and color strength and hiding power, the preservative is paint and light-emitting agent; also excellent ultraviolet shielding ability of zinc oxide to the coating of anti-aging and so have a more prominent feature.
Medical and health and food industry: zinc oxide with Sida, bleeding, myogenic function of convergence, but also raw material for plaster, but also has helped promote the intellectual development of children; zinc oxide for the food needs of the health sector is gradually expanding, However, more stringent product requirements, especially the harmful heavy metals may not excessive.
Glass ceramics industry: zinc oxide in glass used in special; in the ceramic industry, zinc oxide used as a flux. Because zinc oxide fine particles and high activity, can reduce the sintering temperature of glass and ceramics, in addition to use of zinc oxide ceramic glaze is more clean preparation has antibacterial, antifungal, deodorizing effect.
Dyeing and printing industry: zinc oxide used to prevent dye.
Optoelectronics Industry: Zinc oxide varistor is the main raw material is magnetic, optical materials such as the main additive. Prepared using zinc oxide varistor, not only has a low sintering temperature, but also improve the performance of pressure-sensitive resistor, such as the flux, the nonlinear coefficient. Application of zinc oxide in the optical devices will be with the optical properties of ZnO-depth study will be a breakthrough.
It can be predicted, as people continue to explore for zinc, it will play for the progress of human civilization better catalyst.
