Description
Technical field
The present invention relates to a kind of for the deinking agent in paper industry deinking, particularly a kind of environmental type washing method waste paper deinking agent being applicable to flotation process deinking technique.
Background technology
Along with the enhancing day by day of people's environmental consciousness, the recycling of waste paper also more and more comes into one's own, and the benefit of reducing investment outlay, the aspect such as to reduce costs particularly brought after waste paper utilization more brings huge impellent to the reuse of waste paper.Therefore, utilize waste paper to produce paper and paperboard and not only have a great economic significance, and there is very important social effect.
Main source the blank sheet of paper limit having printing house to cut and the printed matter scrapped of waste paper; Periodical, magazine that publisher is expired; The waste and old books and periodicals of machine-operated, industrial and commercial enterprises and institutions, newspaper, printing material and various packing carton, carton etc.; Various old newspapers, waste and old books, magazine, Packaging Box etc. that residential households uses.In order to the waste paper printed being processed into the blank sheet of paper slurry meeting production requirement, deinking agent must being added in repulping of waste paper process and processing, stick to ink on fiber and pigment because of printing to remove.The process of this process is just called deinking.
The ink of printing is mainly dispersed in the particles such as carbon black, pigment and some weighting agents in sticking agent (comprising plant or mineral oil, rosin and sizing material etc.), and these particles stick on paper fibre by printing.Some high-quality ink also can form one deck varnish film at fiber surface.Deinking is exactly be to destroy the adhesive power of these particles to fiber, need to add a little pharmaceutical chemicals and by mechanical external force at a proper temperature for this reason, above-mentioned sticking agent saponification is dissolved, ink and pigment are separated from fiber.Whole process roughly can be divided into following three phases: 1. discongest separated fiber (completing elementary deinking).2. adding chemical makes ink depart from from fiber.3. the ink particle separated is separated from slurry.The ink particle be dispersed in after deinking in paper waste must be removed as early as possible.The at present method having washing method, flotation process and washing flotation to combine that generally adopts of the deinking of waste paper in the world.
Flotation process was used widely in the 1950's, its objective is that ink particle is adsorbed onto on bubble and in company with the bubble of rising to be removed.Flotation ratio juris utilizes the wetting properties of the compositions such as fiber, filler and ink different, and make ink particle be adsorbed on air filled cavity with flotation machine, float on slurry face and remove, fiber and filler are still stayed in slurries.Ink sorptive after separation is on air filled cavity, and foam is formed at the top being raised to groove, then by overflow device, mechanical skimmer or the vacuum suction apparatus skim foam with ink.
Floatation and ink removing can be divided into 4 micro-treating processess:
(1) ink particle disperseed is close to air filled cavity;
(2) in bubble surface slip absorption;
(3) bubble, ink particle and liquid three contacts and reaches balance;
(4) bubble and ink particle stable bond, until removing.
Flotation process is more effective de-inking method, is specially adapted to the scope (being also the scope that most of ink particle is assembled) that ink particle is 10 ~ 15um, and when being less than 10um, flotation process effect is poor.
The advantage of flotation process is that fiber loss is less, and yield is high, pharmaceutical chemicals and water consumption less, pollute few.Shortcoming is the whiteness comparatively low 3% ~ 4%ISO of washing method, and cost of equipment is higher, and processing condition require strict, and power consumption is larger.The larger investment of flotation process floor space is higher, but net effect is better than washing method, saves time, water-saving, province's gas, economize chemical, and the yield of Deinking Pulp is higher, and being comparatively applicable to large-scale paper plant, is the developing direction of deinking.
Nineteen fifties, colonial utilizes flotation process to remove marking ink in waste paper and other objectionable impuritiess.Through the research and development of decades, rapidly, the throughput of Deinking Pulp and quality achieve the development of advancing by leaps and bounds for deinking technology and the development of relevant deinking equipment.
The deinking chemicals adapted with it there has also been very large development.Organic additive is developed into from initial inorganic assistant agent; Develop into compound auxiliary from single auxiliary agent, develop into close to neutral process from the basic treatment that pH is higher, present deinking agent, except will considering good deinking efficiency, also will consider the protection to environment.
But, existing conventional floatation deinking agent, have because of emulsifying property and/or disperse anti-deposition properties bad and cause the ink on waste paper to be not easy to elute, also have because of suds suppressing properties bad, produce too many foam in operation and affect operation.And, existing floatation deinking agent, contain the disagreeableness composition of environment in many kinds, as polyoxyethylene alkylphenol ether (APEO), sodium alkyl benzene sulfonate (ABS) etc., these materials are all prohibited in many countries, they are not only not easy biological degradation, and in use can produce a large amount of foams.
