Description
Technical field
the present invention relates to a kind of solid deinking agent for deinking and its preparation method and application.
Background technology
increase due to plant resources worsening shortages and to the requirement of environment protection, the recycling of regenerated fibre have received the very big attention of countries in the world.The most significant steps of waste paper recycling is deinking step, and the printing-ink using good Deinking Technology to remove paper is the key of waste paper recycling.The mode that current domestic waste paper deinking mainly adopts flotation process and washing method and both to combine, because washing method can expend more paper making water, floatation and ink removing is subject to parent and looks at.
because various waste paper more or less all can through printing treatment, especially old and useless newspaper, post consumer printing papers etc. are through the waste paper of printing containing ink, because the ink in pulping process is not easily removed, and improvement or the lifting of paper strength and optical property is unfavorable for containing the paper pulp that ink is more, so need to carry out necessary deinking process in pulping process, the paper waste quality made after deinking process and optical property will be greatly improved, and its paper waste just can copy raw material as joining of good quality paper.But in deinking process, deinking agent is critical product, excellent deinking agent can reduce production energy consumption and carry high product yield and class, energy-saving and cost-reducing for producing; Simultaneously waste paper deinking agent itself is nontoxic, can natural degradation, and environment friendly is obvious.
for existing various de-inking method, its major technique comprises alkaline deinking, neutral deinking and Enzymatic Deinking.For using anion surfactant and the composite deinking agent of nonionogenic tenside, the soil removability that this kind of deinking agent is good because anion surfactant has, foaminess is good, and foam is thin and stable, especially cheap price; Nonionogenic tenside has abundant species, and good dispersion and emulsion effect, also can have good deinking efficiency under low concentration, and in addition, nonionogenic tenside has good consistency, can be composite preferably with anion surfactant.
because the kind of current printing-ink and quality are updated, a lot of existing deinking agent can not meet the deinking requirement of various waste paper, therefore, develops a kind of cheap and to adapt to the deinking agent of various ink significant.
Summary of the invention
for the problems referred to above, the object of this invention is to provide a kind of solid deinking agent and its preparation method and application, good, the convenient transport of the deinking performance of this solid deinking agent and storage, can be applicable to deinking.
