Abstract
The present invention announces the method that laboratory quickly prepares chromatics paper.Will honed slurry, liquid dyes and auxiliary agent mix after stir, colored wet cake is filtrated to get, by squeezing and drying obtains chromatics paper.This operating process simple and fast, the laboratory that is particularly suitable for use in paper dyestuff relatively.
Description
Technical field
The present invention relates to laboratory field of papermaking, more particularly, to a kind of method of quick internal dying manufacture chromatics paper.
Background technology
When carrying out application assessment to paper pulp, auxiliary agent or papermaking dyestuff, it is necessary to be dyed in laboratory to paper pulp
Processing, to test the performance into paper.Need to heat up mostly during current preparation method dyeing, and also need to use handsheet machine,
Squeezer, paper drying plant etc., the whole manufacturing process time is long, costly and paper is easily deformed etc. and asked when drying be present
Topic, therefore, it is necessary to optimize and innovate for technology at this stage, to find a kind of quick and cheap method.
The content of the invention
The present invention is intended to provide a kind of easy, quick and inexpensive laboratory prepares chromatics paper method.
The present invention, which adopts the following technical scheme that, realizes above-mentioned purpose.
(1) the slurry of milled is weighed, adds water to carry out dissipating slurry after stirring, obtains uniform slurries；
(2) above-mentioned slurries are taken, and the concentration for adding water regulation oven dry stock is 0.1-5wt%, is added under stirring equivalent to over dry
0.1-10wt% liquid dyes are starched, stirring 1-10 minutes are stand-by；
(3) auxiliary agent is continuously added, 1-10 minutes is stirred, chromatics paper wet cake is obtained with filtered on buchner funnel；
(4) wet cake is dried after squeezing on polisher, obtains chromatics paper.
When dissipating slurry, the ratio of over dry slurry and water is 1:20~1:50, slurry can be chemical pulp, mechanical pulp or waste paper
Recovery slurry.The slurries dissipated need to now do current, and the general same day is finished, in order to avoid go mouldy and dehydration.
Selected liquid dyes are obtained after Powder dye dissolves, or the liquid dyes that synthesis directly obtains；Dyestuff
Kind be direct dyes, reactive dye, acid dyes or the dye of positive ion.
Dyestuff and auxiliary agent corresponding to different slurry needs selections, conventional kind of dyes are as follows：Direct dyes, activity dye
Material, acid dyes and the dye of positive ion.The time stirred is added after dyestuff in 1-10 minutes.
The purpose for adding auxiliary agent is chiefly to facilitate the colouring of dyestuff, keeps the characteristic kept with paper of fiber, Ke Yiwei
The combination of single variety or multi items, it is alternative to have：Aluminum sulfate, aluminium polychloride, aldehyde-free colour stabilizer, poly- third
Acrylamide, starch, tannic acid etc..The time stirred is added after auxiliary agent in 1-10 minutes.
The purpose squeezed to colored wet cake is in order that filter cake is more smooth, while also removes part water in filter cake
Point, to save the time that next drying is used.Squeezing can use special squeezer, can also use the modeling of normal office
Envelope machine, but need filter cake to be clipped among the plastic sheet of smooth surface, then by plastic packaging machine, may be reused after plastic sheet washing.
The time dried with polisher is generally 10-20 minutes, need to select that the polisher of temperature and time can be controlled, with
Convenient operation.
At present, the technology of making in laboratory paper substantially also uses paper machine, although can also obtain preferable paper,
It is that the price of paper machine make it that the cost of experiment is very high, and operating process is also relatively long, what a paper machine can be done every time
Paper is limited.This method is easy to operate, efficiency high and cost are low, is adapted to the handsheet process of routine experimentation room, is particularly suitable for use in pair
The detection of paper dyestuff performance, by practice for many years, it was demonstrated that the method can substitute the result of handsheet machine.
