1. zinc oxide uses

1.1 in the ceramic industry in the application

Zinc oxide is an important chemical flux of ceramic raw materials, building ceramics, tiles, glaze, enamel materials and low temperature in the amount of more artistic ceramic glazes. Zinc oxide in the glaze has a strong fluxing action, to reduce the expansion coefficient of the glaze, improve the thermal stability, and can increase the luster and white glaze, improve the flexibility of the glaze. At the same time expanding the scope to increase the melting glaze glory.

1.2 In the electrical and electronic industry applications

our ongoing "West to East" a major project in the large transmission lines, you need to install arresters, to achieve safe power transmission purposes. New development at home and abroad to meet the MOA needs.

zinc oxide can be made transparent conductive film, a transparent electrode, with a certain method for producing zinc oxide semiconductor thin film having a light emitting characteristics, but also A zinc oxide varistor may be used as sensors.

1.3 in the plastics and rubber industry applications

active zinc oxide as a reinforcing agent in rubber and accelerators, rubber products to improve wear resistance, anti-aging, anti-friction ignition, longer life, etc., and to decrease the amount of rubber 3 to 7 percent. Zinc oxide whiskers can be made, such as an epoxy resin composite material has the effect of damping and enhanced performance. Using special methods, zinc oxide can also be made semi-conductive powder, paste and filling agents , can be made electrically conductive plastics and rubber products. Active zinc oxide can also be applied in the tire.

1.4 in the coatings industry in the application < / p>

< font size = "3"> zinc oxide is white, also known as zinc white, odorless and tasteless, in the natural environment is relatively stable, can be used as a substitute for the expensive titanium dioxide. Meanwhile, the zinc oxide also has the ability to absorb ultraviolet light in the coatings industry has been a certain degree of application.

1.5 in commodities and application < / p>

< font size = "3"> ZnO with anti-IR, UV and bactericidal function, has been widely used type of sunscreen, antibacterial and UV resistant new functional fiber, antibacterial self-cleaning glass, ceramic, anti-infrared, ultraviolet shielding materials, sanitary ware, wastewater treatment and photocatalytic materials and other products. In addition, in the field of environmental protection zinc oxide also has a special significance.

2. Project Features

micronized zinc oxide production in recent years the rise, yields small. ZnO powder is still in development and small batch production. Main preparation methods are: chemical vapor deposition method, gas-liquid reaction synthesis method, a laser-induced method, high-frequency plasma pyrolysis method and sol - gel method. Preparation is the key to the purity of the powder, particle size, morphology, surface properties and dispersion and so on. Preparation of zinc oxide powder with zinc carbonate precursor, basic zinc carbonate, oxalate, zinc hydroxide. This project can be combined with the characteristics of regional resources, production of zinc oxide according to market conditions.

2.1 small investment, you can use industrial waste

This project zinc oxide with various existing production technology, compared with the following characteristics:

( 1) simple equipment, without calcination, acid, dust collection systems, smaller investment;

< span style = "LINE-HEIGHT: 150%; FONT-FAMILY: Arial; mso-font-kerning: 0pt; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: Arial"> (2) low cost, has occupied the market price advantage;

(3) high product quality, product quality and stability, dominate the market quality advantage;

(4) tailings and refractory mineral raw materials can be used, also can use a variety of industrial waste fluid and waste, improve enterprise efficiency and protect the environment, sulfur is recovered in the form of sulfur in the market selling;

(5) process operation is relatively simple, easy to grasp;

(6) workshop better working conditions, no environmental pollution.

2.2 good quality products

from zinc sulfate, zinc chloride and other basic zinc carbonate precursor was prepared , using calcination post-treatment processes. Particles made of high purity, with a specific function while maintaining the characteristics of nano-powder, high temperature calcination process to overcome the growth disadvantage nanoparticles; loose powder prepared simultaneously, to facilitate further handling and use. Through a special process, the powder surface treatment, increase surface activity.

3. raw material sources

3.1 tailings and refractory mineral < / p>

< font size = "3"> After a lead-zinc ore mined minerals, concentrates sold to overseas smelters, but also produce many tailings. Meanwhile in the screening process, there is a certain amount of refractory lead-zinc. For zinc ore tailings and difficult, because there is no suitable method of treatment and recovery process, only stockpiling. Enterprise efficiency and the environment against adverse effects.

3.2 all kinds of industrial waste

use of zinc-containing waste can be recycled and the pharmaceutical industry and to prepare high-quality basic zinc carbonate. Machinery factory emissions of zinc chloride-containing waste, which can be recycled and prepare basic zinc carbonate. Rayon plant waste can also be recycled and prepare basic zinc carbonate.

3.3 < span style = "LINE-HEIGHT: 150%; FONT-FAMILY: Arial; mso-font-kerning: 0pt; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: Arial"> zinc processing generated from the metal scrap, zinc scrap, waste catalyst linking alcohol, sub-acid leaching of zinc oxide waste, waste zinc oxide desulfurizer (such as nitrogen fertilizer plant waste zinc oxide desulfurizer), waste batteries, etc. and can be recovered in both the preparation of basic zinc carbonate.

4. Market and benefits forecast

domestic market better senior zinc oxide , 2007 In ordinary zinc oxide The price of 2.5 ten thousand yuan , high purity zinc oxide prices 3.5 million. High purity zinc oxide high activity higher prices.

The new annual output of 1000 t grade zinc oxide plant, equipment investment, including leaching, purification, finished, power (capacity 200kW ), water ( 100t / d ), boilers ( 2 ~ 4t ), tools, vehicles, etc. about 300 million, working capital 300 million. Economic efficiency: the annual output value 2500 < / span> million (zinc oxide + Senior sulfur powder products), product cost 1500 yuan, annual profit of about 800 million in equipment investment payback period less than one year, significant economic benefits. Such as the use of existing chemical transformation, better efficiency.

5. Project Features

R & D staff of the project respond to national call, the use of green chemistry concepts and methods of recycling economy, the production process does not pollution, no emissions, waste, waste water and other waste. In the use of industrial waste produced ZnO can also make use of other chemical wastes, can produce a variety of important chemical raw material, high value-added products, the plant's economic efficiency, ability to withstand market risks.
