Abstract
The present invention belongs to paper making technology, particularly to a method for producing rust preventing raw paper by using waste ramie, which uses waste ramie as a raw material. The waste ramie is cut off, treated by dust removal, preliminarily dipped, and placed into a spherical boiler to be boiled. A boiling agent is urea and sodium hydroxide, and a catalyst is sulfur. The present invention uses the waste ramie as the raw material for producing the paper, sufficiently makes use of regenerating resources, and is helpful for reducing the production cost. The industrial waste liquid of the present invention belongs to the nitrogenous fertilizer, is easy for biochemical treatment and can be used for preparing a compound fertilizer. The present invention is helpful for environmental protection, and the comprehensive economic benefit is high.
Description
The invention belongs to paper technology, more precisely is a kind of method of utilizing waste ramie to produce anti-rust base paper.
Waste ramie refers to useless gunnysack, the useless rope made of hemp, industry or the discarded gunny products of life, and these discarded objects are generally done garbage disposal, and in fact this also is a kind of waste of resource.Chinese large-sized iron and steel enterprise year needs 30,000 tons of volatile rust preventive papers at present, and the raw material of this paper almost all adopts needle timber, and the needlebush speed of growth is slow, is a kind of Limited resources.And waste ramie is a kind of raw material that can make anti-rust base paper.
Given this, the object of the present invention is to provide a kind of method of utilizing waste ramie to produce anti-rust base paper, by the anti-rust base paper intensity height that the present invention produces, comprehensive good physical and chemical properties, cost is low.
Purpose of the present invention is achieved through the following technical solutions: a kind of method of utilizing waste ramie to produce anti-rust base paper, with the waste ramie is raw material, waste ramie is cut off, soak, drop into rotary spherical digester through dedusting, son, carrying out boiling handles, digestant is urea and caustic soda, and catalyst is a sulphur, and wherein each medicine to the percentage by weight of waste ramie is:
Urea 6-10%
Caustic soda 4-2%
Sulphur 0.5-2.5%
Conditions of cooking is: liquor ratio: 2.3-3.4
Heating-up time: 0.45-1.30 hour
Holding temperature: 140-165 ℃
Insulation: 1.30-3 hour
Afterwards, gained paper pulp is produced anti-rust base paper by paper machine.
Embodiment gets 100 kilograms of grain depots and scraps gunnysack, through dedusting, give and soak, drop into rotary spherical digester, carries out boiling and handles, and digestant is urea and caustic soda, and catalyst is a sulphur, and each medicine to the percentage by weight of waste ramie is:
Urea 8%
Caustic soda 3%
Sulphur 1.5%
Conditions of cooking is: liquor ratio: 3
Heating-up time: 1 hour
Holding temperature: 150 ℃
Insulation: 2 hours
Afterwards, gained paper pulp is produced anti-rust base paper by paper machine.
These useless fiber crops are paper making raw material with the waste ramie, make full use of regenerated resources, help reducing production costs.Urea among the present invention is main digestant, helps preventing the carbon steel equipment corrosion, for having positive effect the service life that prolongs equipment; its industrial wastes belongs to nitrogenous fertilizer, is easy to biochemical treatment, and can produce compound fertilizer; help environmental protection simultaneously, the overall economic efficiency height.
