Qingdao Sunaswan Industry Co., Ltd. is a leading national supplier of lignin-based binding/dispersing serial products. We produce and trade mainly with lignosulphonate technical powder sodium, calcium and magnesium.
For years of devotion to innovation and development, we have gained a good reputation in the industry. And become the market-leader in some key segments that we represent.
In recent years we focus on the research and development of advanced technology for producing sodium lignosulfonate (SLS) by using corncob as a single raw material. About 12% sodium sulfite is added to the production process for cooking, boiled solution is separated by chromatography after mechanical vapor compression and then reconcentrated to produce SLS aqueous solution WS-2 (sugar content is more than 10%). while WS-1 (sugar content less than 10%) was obtained after reducing sugar and modification. SLS powder was obtained by spray drying of the liquid.
We are engaged in manufacturing and delivering value-added, high performance, environment friendly lignin-based products to our customers, our expertise enable us to servicing industries in construction, carbon black, ceramics, textile, agriculture, leather tanning, oil drilling and so on.
Besides selling, our company provides engineering solutions to help our clients cut product development costs, extend capacity and maximize profitability. Our professional team consists of R&D center and Sales crew take part in the process of developing-producing-marketing, provides ongoing service with regular status updates on your orders. The target is to make sure the products can meet the specific requirements of our customers. For this, we always at unremitting efforts and continuously pursue to provide not merely the products but also essentials to creation of our customers at home and abroad.
Outline use for lignosulphonates
lignosulfonates, or sulfonated lignin, (CAS number 8061-15-6) are water-soluble anionic polyelectrolyte polymers, they are byproducts from the production of wood/natural plants pulp using sulfite pulping. Lignosulfonates have a wide variety of applications in the fields of agriculture & forestry, petroleum, metallurgy, colorant, cement, concrete and polymers industry. Act as plasticizers in making concrete , where they allow concrete to be made with less water (decrease water consumption by 10-15% so as to giving stronger concrete) while maintaining the ability of the concrete to flow.
used during the production of cement, where they act as grinding aids in the cement mill and as a raw mix slurry deflocculant (that reduces the viscosity of the slurry).used for the production of plasterboard to reduce the amount of water required to make the stucco flow and form the layer between two sheets of paper. The reduction in water content allows lower kiln temperatures to dry the plasterboard, saving energy.
The ability of lignosulfonates to reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho or needle wood.To be used to disperse pesticides, dyes, carbon black, and other insoluble solids and liquids into water. They are used in tanning of leather, ceramics, mineral powder, textile, refractory, rubber reinforce agent, They are also used to suppress dust on unpaved roads.
We are committed to the R&D and utilization of cob-made sodium lignosulfonate, not only for the benefit of the company, shareholders and employees, but also for the welfare of farmers and communities at the same time. Most of the corn cobs and stalks in the country go to burn on the spot after the corn harvest, and our company bought the "waste" from farmers at a relatively high price, excavated the commercial value of the corn cob, and eliminated the air pollution caused by burning. Therefore, this project is a multi-benefit sustainable development of the green biomass industry.
In addition to lignin, there are two other components, cellulose and hemicellulose exist in wood and plant straw, of which account for about 55% and 11.5% respectively (lignin 30%).
So our business scope also includes: Xylose and L-arabinose are produced from hemicellulose. Using cellulose to produce multiporous cellulose for friction materials, and graphene, a new material of glabal hot-spot, its applications in functional fibers, anticorrosive coatings, new energy batteries, composite new materials are developing. The remaining residue can be used to produce organic fertilizer. All products will be published on this website one after another.
