Chemical Applications For Paper
Handan Fengfeng Refractory Co., Ltd. Fuxin Mining Meng Niu Yun is pleased to introduce engineers yesterday: they developed black granulation Additive Due to help enhance strength and uniformity of carbon black particles, reducing carbon emissions and carbon black company much sought after products have been in short supply. There are also exciting Weihe River in Shaanxi and Henan Science and Technology Co., Ltd. Anyang auxiliary loop, the two companies, and they produced CWS and very teas sell all kinds of dispersants.
Teas sell the products of these enterprises are lignosulfonate products. The relevant parties understand that these products are easy to manufacture, papermaking waste water by chemical neutralization, precipitation, condensation, drugs floating, flotation and membrane separation comprehensive treatment, the lignin can be obtained with high purity sulfur calcium lignin sulfonate and other products. Can be said is turning waste into wealth Competition. Currently, coal Chemical industry Lignosulfonate in areas such as increasing demand for such products, to promote the rising prices, to stimulate more business from the papermaking waste water, “Gold Rush”, paper making enterprises to mobilize the enthusiasm of wastewater treatment, and then promote the build Paper Energy conservation.
As a cheap high-quality dispersant, lignosulfonate has widespread applications, and with the improvement of its quality and performance, the current applications are still expanding. Among them, carbon black, coal-water slurry additives, cement water reducer, lignosulfonate emulsion is the most potential applications.
Weifang, Shandong, according to Cologne than willing Chemical Co., Ltd. General Manager Wang blunt description: wet granulation process, each ton of carbon black, need to add 1.5% to 2% calcium lignosulfonate. 2010, China’s carbon black production capacity will reach 5 million tons, the demand on calcium lignosulfonate of about 50,000 tons. To “12 5” end of the carbon black industry’s demand for calcium lignosulfonate more than 100,000 tons.
Order to increase the mobility of high concentration coal-water slurry, coal-water slurry is usually required to add 0.5% to 3% of the lignin sulfonate. At present, China has reached the CWS gas plant processing raw materials on the scale of 30,000 tons of coal, the annual needs of about 150,000 tons of lignin sulfonate, is expected in the field of coal chemical industry such as lignin sulfonate dispersant demand will average increase of 15% or more, to “12 5” end of the field of lignin in sodium consumption will reach 250 thousand tons.
In Furniture Areas with concentration of 80% to 90% of lignosulfonate colloids replace the current 40% general Phenol ? Formaldehyde resin adhesive, not only low cost, and good adhesive effect, the product sound Environmental protection . The next few years the demand for the area of lignin will reach 100,000 tons.
In the cement, the cement production in China is the world’s first consumer, as long as the cement with 0.5% lignin, can significantly improve the performance of cement, even if only 1 / 3 of the cement adding lignin sulfonate calcium, one-year demand will more than two million tons.
To “12 5” at the end, only the four areas on an annual consumption will reach 3 million tons of lignin sulfonate, together with other areas, the total demand is expected to more than 3.5 million tons. At present the country’s total annual capacity planning lignosulfonate 500,000 tons, a huge development potential.
Huge market means that lignosulfonate treatment of papermaking wastewater, water resource utilization to achieve, by the paper companies have to meet increasingly stringent state environmental regulations and corporate survival requirements upset and become profitable business practices. To account for 65% share of China’s Papermaking, for example, because of its wastewater COD, BOD, total suspended solids and a variety of metals, non-metallic ion content, the component complexity of dealing with difficult, high cost, has been affected enterprises wastewater treatment initiative. But the straw pulp wastewater is very high lignin content, usually from 6% to 8%. Enterprises by domestic wastewater straw pulp production capacity (mainly black water, gray water and white water) 15 ~ 20 tons / ton calculated that if all the recycled paper business and its extract lignin sulfonate per ton of finished product is paper waste generated can be extracted from 1 to 1.5 tons of high purity calcium lignosulfonate product.
