Product Details A method for using lignin as a rubber reinforcing agent belongs to the technical field of lignin application in rubber industry. The main point is to add formaldehyde to the concentrated papermaking waste liquid to make lignin formaldehyde resin, and then add sulfur, zinc oxide, stearic acid, vulcanizing agent, vulcanization accelerator, vulcanization activator and rubber in proportion to vulcanize at a certain temperature. At the same time, the vulcanized rubber does not fly dust and pollute the environment during vulcanization, and the papermaking waste liquid is harmful to benefit, and has great social and economic benefits. The main uses of sodium wood are widely used in various industries due to its adhesion, dispersibility and chelation properties to improve its physicochemical properties, save costs and improve rates. 1 The reinforcing agent plays the role of water reduction, plasticization, flocculation, etc. in the production of refractories and ceramic products. It can also be used in the foundry industry. 2 Ore powder binder The smelting industry mixes ore powder with it to make ore powder balls, which are dried into kilns to improve the smelting recovery rate, and can also be used as a beneficiation agent. 3 When the mixing amount of concrete water reducer is 0.2%-0.3%, it can reduce the water consumption during concrete mixing by 10%-12%, reduce the water-ash ratio, save about 10% of cement, improve the ease, fluidity and anti-permeability of concrete, improve the strength and compactness of concrete, have an early strength effect, shorten the setting time, improve the compressive strength, and reduce the loss of concrete slump. 4 Scale inhibitors and corrosion inhibitors are used in industrial containers and pipelines to prevent scale and corrosion, and improve the service life of windows and pipes5 Coal water slurry dispersants are used in thermal power plants and other enterprises that use coal slurry. As dispersants, they improve the dispersion capacity of coal, increase the calorific rate and utilization rate of coal combustion, greatly reduce the coal content in fly ash, and reduce bypass and caking, and improve the life of the furnace body. 6 In addition, this product can be used as a chemical agent for tertiary oil extraction, a diluent for oilfield drilling mud, and for sealing wells. In addition, it can also be used as asphalt emulsifier, feed binder, refining aid, etc. It is also widely used in pesticide processing, briquette production, tanning leather filler, carbon black granulation and soil, sand dune, fan gel control, etc.
