AI Technical Summary

Problems solved by technology

However, the pre-impregnation effect of wood chips and straw fibers is not good, which will increase the power consumption of refining and reduce the strength of pulp.
Under the conditions of high torque, high tearing, and high concentration of biological enzyme chemicals, the loss of wood chips and straw fibers will increase; at the same time, the wear of the screw shaft, blades, screen frame, and anti-skid strips will increase, and the service life will be shortened.

Abstract

The invention discloses a special softener for bio-enzyme pulping, which is prepared from the following components: a penetrant BS; sodium diethylhexyl sulfosuccinate; isomeric alcohol ethoxylate; peregal O; fatty alcohol-polyoxyethylene ether; alkyl sodium sulfonate; coconut diethanol amide; sodium hexametaphosphate; sulfamic acid; sodium citrate; and water. The softener ensures that wood chip and straw fibers are easy to mill, reduces the energy consumption of pulping, prolongs the service life of a mill, reduces the dosage of bio-enzyme, reduces the discharge of COD (chemical oxygen demand)in wastewater, and not only can bring economic benefit, but also has environmental protection benefit. The invention further discloses a preparation method for the softener. The manufacturing processis simple, paper products with higher physical strength can be produced, moreover, yield pulp is high, the softener has wider applicability, and can replace more chemical pulps for papermaking, and more resources can be saved; furthermore, the loss of wood chip and straw fibers is reduced, the pulping yield is higher, the COD content in wastewater is reduced, and the invention is of great significance in saving energy, reducing discharge and saving resources.

Description

Technical field [0001] The invention relates to the technical field of biological enzyme pulping, in particular to a special softener for biological enzyme pulping and a preparation method thereof. Background technique [0002] Biological enzyme pulping is a type of pulping method developed in the 1990s. Its basic feature is to use a small amount of biological enzymes to pre-impregnate the raw materials to soften the biodegradation of the fibers, and then grind them into different properties by grinding. pulp. Because only a small amount of biological enzymes are used in the process, the utilization rate of the fiber raw materials in the biological enzyme pulping is much greater than that of the chemical pulping (the yield can reach more than 90%), and at the same time, it produces less pulping wastewater and lower The pollution load; its application range is wider, and it can even be used to replace chemical pulp in some paper types to reduce the production cost of paper produc...
