Operation method capable of quickly measuring pulp beating degree of wastewater in furniture factory

Abstract

The invention discloses an operation method capable of quickly measuring the pulp beating degree of the wastewater in a furniture factory. The method comprises the following steps: adjusting the placement position of an instrument to enable a copper net to be kept horizontal, pouring water into a water filtering cylinder to check whether a cone-shaped cover leaks water or not, and cleaning the instrument; and thoroughly cleaning a separation chamber and the water filtering cylinder, mounting the water filtering cylinder on the separation chamber, putting the cone-shaped cover at a closed position, pouring distilled water or ion exchange water at 20+ / -1 DEG C into the water filtering cylinder to adjust the temperature of the instrument, lifting the cone-shaped cover until the water is discharged completely, placing an SR measuring cylinder below a side flow pipe, putting 1000+ / -5mL of prepared pulp suspension into the measuring cylinder, stirring the suspension uniformly, then pouring the suspension into the water filtering cylinder immediately, lifting the cone-shaped cover after five seconds, discharging filtered water passing through the copper net from bottom holes and a lateral flow pipe respectively via the separation chamber, and reading a degree value of SR, namely a measured result. According to the method, the pulp beating degree of a sizing agent in a pulp can be accurately measured, the pulp beating quality is enabled to meet requirements, and meanwhile, useless work is avoided, the quality of subsequent products is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method, in particular to an operation method capable of rapidly measuring the beating degree of slurry in wastewater from furniture factories. Background technique [0002] Slurry is an organic substance with general colloidal properties. It can dissolve or swell in water and become a viscous and plastic paste. It can be used as a transfer agent for bringing dyes and other chemicals to fabrics. After printing and color fixing are completed, finally is washed away. The paste itself does not participate in a series of chemical reactions in printing, but only acts as a medium. The slurry should be completely uniform, and there should be no coarse particles of undissolved matter, yarn ends, fluff, etc., and no hard sand or metal debris left in the slurry. Therefore, pre-filtering and accelerated stirring should be performed before printing. There are many kinds of rubber materials, including pulp, also known as paper material. ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above problems that the degree of beating of the existing slurry is judged by the operator based on experience, resulting in uncontrollable quality, waste of resources, and high production costs. The operation method of the beating degree of the material, the method can accurately measure the beating degree of the slurry in the slurry, so that the beating quality meets the requirements, and at the same time avoids useless work, improves the quality of subsequent products, reduces production costs, and solves the problem of existing slurry The degree of beating is judged by the operator based on experience, resulting in uncontrollable quality, waste of resources, and high production costs
