Description
【Technical field】
The invention belongs to unbleached paper preparing technical fields, and in particular to a kind of secondary pretreatment immersion liquid B and its numb preparing
The application of bamboo true qualities paper pulp.
【Background technology】
The production method of paper pulp includes mainly the productions streams such as chemical method, semichemical method, Mechanical Method and chemical mechanical pulping at present
Journey.Wherein chemical pulping is occupied an leading position among current numerous pulping process.Claim by paper pulp made from chemical method boiling
For true qualities paper pulp, true qualities paper pulp limits its application since whiteness is relatively low, and true qualities paper pulp will could generally give birth to after bleaching
Produce the paper kind of higher level.If the whiteness of true qualities paper pulp can be improved in pulping process, the fiber crops of following bleaching can be saved
It is tired, simplify production procedure, reduces production cost, and improve the use value of true qualities paper pulp.
In the production process of true qualities paper pulp, for wood raw material, carried out using sodium hydroxide and vulcanized sodium in pulping process
The sulfate process of boiling is main pulping process, and small part uses sulfite pulping, but these use sulfur-bearing chemicals
The method of boiling there are the problem of be exactly can environmental danger.For non-wood material, soda processes or burning are mainly used at present
The problem of soda-AQ qulping, this pulping process is difficult to recycle presently, there are waste liquid.In addition, either sulfate process, caustic soda
Method or alkali-AQ pulping, since the lignin in raw material is condensed in digestion process, the true qualities pulp brightness of gained is all
It is relatively low, therefore development of the free of contamination novel high whiteness true qualities paper pulp manufacturing technique for paper industry is sought with important meaning
Justice.
A kind of patent document " true qualities method of manufcturing paper pulp (Authorization Notice No. improving pulp brightness：CN103924470B)”
A kind of production method for the true qualities paper pulp improving bamboo paper pulp brightness is disclosed, this method includes locating bamboo raw material SODIUM PERCARBONATE in advance
After reason, then with the mixed organic solvents of formic acid, acetic acid and acetone boiling is carried out, the paper pulp after boiling uses formic acid and hot water wash
It washs, finally prepares true qualities paper pulp, however gained bamboo paper pulp yield and whiteness are still relatively low.
With the continuous expansion of paper industry, constantly opening up for pulp applications is wide, originally the wood as main paper making raw material
Gradually supply falls short of demand for material, and forest is caused excessively to be cut down, and influences ecological environment, therefore, it is necessary to seek new raw material substituent.
Sinocalamus latiflorus (Dendrocalamus latiflorus Munro) is that south China cultivates most wide one of bamboo kind, is standing grain
Undergraduate course (Poaceae) Bambusoideae (Bambusoideae) Dendrocalamus (Dendrocalamus) large-scale sympodial bamboo kind, is distributed mainly on
The provinces and regions such as Fujian, Taiwan, Guangdong and Guangxi Provinces, Yunnan, Hainan, Sichuan, the Guizhou middle and south, for edible, timber-used, Ye Yong, water and soil conservation, greening
The multipurposes bamboo kind such as ornamental, to produce bamboo shoot or do based on pulpwood.Sinocalamus latiflorus growth is fast, the bamboo shoot phase is long, yield is high, bamboo shoot are of fine quality good, sinocalamus latiflorus
Fast growing, widely used, primary plant utilizes for many years, is that a kind of economic value is high, excellent calculation material profitable on ecology is dual-purpose
Bamboo kind, economic benefit, ecological benefits and social benefit Three benefits are notable.
Therefore be conducive to avoid result in forest and excessively cut down as substitution wood raw material using artificial growth sinocalamus latiflorus, influence
Ecological environment.

Can it is found that being not added with percarbamide, amino carboxylic acid, vanadic anhydride in secondary pretreatment immersion liquid B by comparative example 1-4
Paper pulp yield and whiteness are reduced, this is because percarbamide can slowly release hydrogen peroxide, the hydrogen peroxide released and wood
Element reaction is conducive to improve paper pulp yield and whiteness；Amino carboxylic acid can play chelation；Vanadic anhydride plays the work of catalysis
With；Understand that percarbamide, amino carboxylic acid, vanadic anhydride add by the paper pulp yield and whiteness of example 3 and comparative example 1-4 simultaneously
Add and play synergistic effect, improves paper pulp yield and whiteness.
By comparative example 5-7 it is found that being once not added with alkyl phenol polyoxyethylene ether, triethanolamine, tristearin in pretreatment immersion liquid A
Acid, oleic acid, lauric acid can reduce paper pulp yield and whiteness, this is because alkyl phenol polyoxyethylene ether, triethanolamine are moistening
Agent plays good humidification；Stearic acid, oleic acid, lauric acid play sinocalamus latiflorus piece surface-active action；Simultaneously by example 3
With the paper pulp yield and whiteness of comparative example 5-7 known to alkyl phenol polyoxyethylene ether, triethanolamine, stearic acid, oleic acid, lauric
Addition plays synergistic effect, improves paper pulp yield and whiteness.
In addition, by with upper table it is found that paper pulp yield and whiteness made from the preparation process of the present invention be significantly above it is existing
Paper pulp yield made from technology and whiteness.
