Problems solved by technology

Although the papermaking industry can bring people the paper they need, but vulcanization is required in the papermaking process, chlorine dioxide and some other harmful odorous substances will be produced, and the waste water produced by the papermaking industry will also have a strong odor, and the manufacturer must carry out decontamination Smelly
[0005] Deodorant is a deodorizing substance commonly used in the paper industry. Although the existing deodorant has a certain deodorizing effect, the deodorizing effect is not good. It is necessary to use a large dose of deodorant to achieve the deodorizing effect. Increased production costs for manufacturers

Abstract

The invention discloses a deodorant for the papermaking industry and a preparation method thereof, and aims to solve the problem caused by a large use dosage of a deodorant in the existing paper making industry. The product comprises the following raw materials by weight: 35-44 parts of ferrous sulfate, 22-27 parts of ammonium persulfate, 25-30 parts of ammonium sulfite, 2.4-3.5 parts of zinc chloride, 0.4-0.65 part of sodium tripolyphosphate, 0.6-1.1 parts of carboxymethyl cellulose and 2.8-5.5 parts of magnesium sulfate. The product is wide in raw material source and simple in preparation process; through the synergistic effect of various raw materials, the prepared finished product has a good deodorization effect and low usage amount, the production cost is reduced, environmental pollution caused after a large number of deodorants are used is also reduced, the environmental protection requirement is met, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a deodorant for the papermaking industry. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. Paper does not exist naturally, but is made by people. [0003] Papermaking includes both machine-made and manual forms. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing, and then dried into paper. By hand, a frame with bamboo screens, polyester nets or copper nets is used to copy the fibers dispersed and suspended in water into wet pape...
