Description
Technical field
The invention belongs to the processing technology fields of rice paper black liquor, and in particular to a kind of rice paper black liquor pretreatment agent.
Background technology
Pulping and papermaking industry is one of the industry of current serious pollution water environment, and pollution sources are straw pulp black digestion liquids, are produced
Raw CODcr accounts for about the 70% of paper industry, and the raw materials such as stalk of paper making raw material contain cellulose, lignin and half fiber
Cellulose therein (accounting for about 40%) is only taken in plain (glycan class) three parts of dimension, papermaking, and wherein account for about 25% lignin with
Account for about the objects such as 28% hemicellulose and xylose, potassium, nitrogen, phosphorus, then it is discarded with black liquor.In recent years, around wastewater black liquor
It handles this difficult point and has carried out many-sided research, lignin therein and hemicellulose are efficiently separated, it could be to obtained material
It is effectively treated respectively, therefore how to detach lignin and hemicellulose in black liquor is the problem of needing research at present.
Application No. is 201510645504.3 to disclose a kind of rice paper black liquor pretreatment agent, includes the group of following parts by weight
Point：20-35 parts of bodied ferric sulfate, 8-15 parts of aluminium chloride, 6-10 parts of poly- phosphorus aluminium chloride, 8-15 parts of ammonium polyacrylate, 2- miaows
2-4 parts of oxazolidone, 1-3 parts of dimethyl silicone polymer, 2-4 parts of modified polyamide epichlorohydrin resin, hydroxyl poly dimethyl silicon
0.2-0.6 parts of oxygen alkane, 0.4-1.2 parts of bi-imidazolidinyl urea, 0.1-0.2 parts of methylene-bisacrylamide, 1-8 parts of PH conditioning agents,
Surplus is water.The present invention has the following advantages compared with prior art：Pretreating agent in acid condition, passes through solution in the present invention
The action breaks down cellulose of middle modifying agent and hemicellulose, lignin link, and make polymer adsorption lignin, cellulose and half
Cellulose, is allowed to reach with other substances in black liquor and detaches, easy to operate, is easy to promote, but the product acid of invention manufacture
Property it is too strong, manufacturing process be easy operator is damaged, it is most important that, especially pollute environment.
Invention content
The purpose of the present invention is the problem of how detaching lignin and hemicellulose in black liquor be directed to, a kind of rice paper is provided
Black liquor pretreatment agent.
The present invention is achieved by the following technical solutions：A kind of rice paper black liquor pretreatment agent, including following parts by weight
Component：A kind of rice paper black liquor pretreatment agent, which is characterized in that include the component of following parts by weight：20-35 parts of bodied ferric sulfate,
8-15 parts of aluminium chloride, 6-10 parts of poly- phosphorus aluminium chloride, 6-7 parts of ammonium polyacrylate, 2-4 parts of 2- imidazolidinones, poly dimethyl silicon
1-3 parts of oxygen alkane, 2-4 parts of modified polyamide epichlorohydrin resin, 0.2-0.6 parts of hydroxyl dimethyl silicone polymer, double imidazolidines
0.4-1.2 parts of base urea, 0.1-0.2 parts of methylene-bisacrylamide, 3-5 parts of PH conditioning agents, surplus are the ammonia of a concentration of 2%-3%
Aqueous solution.
As further improvement of these options, modified polyamide epichlorohydrin resin is by adipic acid, thiocarbamide, diethyl
Alkene triamine is with 5:4:8 composition by weight ratio is heated to 160-200 DEG C, is kept for 3-4 hours, to polyamine epichlorohydrin resin
It is modified.
As further improvement of these options, the PH conditioning agents include alkaline conditioner and acid regulator, alkali
Property conditioning agent be potassium hydroxide, sodium hydroxide, sodium bicarbonate, one or more of sodium dihydrogen phosphate mixture；Acidity is adjusted
Agent is one or more of citric acid, hydrochloric acid, adipic acid, phosphoric acid, tartaric acid mixture.
As further improvement of these options, the preparation method of black liquor pretreatment agent is：
(1) polymerization iron sulfide, aluminium chloride and poly- phosphorus aluminium chloride are added in the sealing container for filling ammonia spirit,
It is warming up to 55-65 DEG C, dimethyl silicone polymer is added and hydroxyl dimethyl silicone polymer stirs 20-40 minutes；
(2) ammonium polyacrylate and methylene-bisacrylamide are added in step (1) acquired solution, is warming up to 80-90 DEG C,
Reaction 1-3 hours；
(3) solution PH is adjusted to 7-9 with PH adjustment agent, surplus stock is added, is kept for 70-80 DEG C, it is small to be stirred to react 1-2
When, obtain product.
The present invention has the following advantages compared with prior art：(1) sealing strip of the pretreating agent in close neutrality in the present invention
Under part, is linked by action breaks down cellulose and the hemicellulose of modifying agent in solution, lignin, keep polymer adsorption wooden
Element, cellulose and hemicellulose, are allowed to reach with other substances in black liquor and detach, easy to operate, are easy to promote；(2) it pre-processes
Agent is greatly reduced to pollution caused by environment, and safety coefficient improves, and prevents caused by operator close to neutrality
Damage.

Embodiment 7
Paper-making black liquid quantitatively detects the content of fiber substance in black liquor with spectrum analysis in experiment, by embodiment 1-
Reagent is added by the 3% of black liquor parts by weight in black liquor in 3, stands 2 hours after stirring evenly, precipitation is filtered out, is detected again black
The content of fiber substance, detection data are as follows in liquid：
Table 1
It can be seen from the data in Table 1 that being removed obviously using cellulose substances in the invention, rate of deposition averagely reaches
91%, although relative to technical solution disclosed in documents, have dropped, the present invention is more environmentally friendly and safer,
Obviously still in acceptable range, wherein component ratio effect is preferable in embodiment 2, by the fiber substance after black liquor pretreatment
It is directly further processed with black liquor, is that black liquor processing is more efficient convenient.
Without using ammonia spirit, effect almost all loses.
Without using sealing container, it is sealed operation, but naked dew operates, also almost all loses effect.
