Description
Technical Field
The invention relates to the technical field of preparation methods and devices of papermaking defoaming agents, in particular to an intelligent preparation method of a papermaking defoaming agent.
Background
The foam in the white water of the papermaking is mainly derived from a plurality of chemical auxiliary agents added into a pulp chest in the pulping process, such as filter aid, retention aid, wet strength agent, sizing agent and the like, which are easy to generate air bubbles in the pulping and white water closed circulation processes, because the pulp contains very fine fibers, pigment fillers and the like, the solid matters provide carriers for the adsorption of the air bubbles, according to the difference of the fibers, the solid matters are adsorbed on the surfaces of the fibers, are penetrated into the fibers, and simultaneously the fine pigments and the fillers are easy to agglomerate on the surfaces of the air bubbles, so that the strength of the foam is enhanced, certainly, a plurality of fine air bubbles are not queued to be dispersed in the pulp, when the content of the air bubbles in the pulp is high, the air bubbles are easy to be combined and large to be combined, the large air bubbles are easy to float on the liquid surface due to small density, namely the liquid surface foam which is usually seen by us, compared with the fine foam adsorbed on the fibers in the pulp, the foam on the liquid surface is large, and the foam on the liquid surface can also be factors such as foam generated by mixing a large amount of air into water due to the factors of unclean slurry washing, incomplete fiber swelling, falling of the slurry in a waterfall shape, air leakage of a slurry pump and the like;
the papermaking defoaming agent is designed aiming at the foaming characteristic of the papermaking process in the papermaking industry, can effectively control the overflow of paper pulp and foam and improve the papermaking quality by using the papermaking defoaming agent, is widely applied to defoaming of papermaking systems, and is used in the pulping production: the defoaming agent used in pulp washing mainly comprises a hydrocarbon defoaming agent containing hydrophobic particles and an organic silicon defoaming agent, and has a good defoaming effect on high-temperature and high-alkalinity black liquor. Among them, silicone antifoaming agents are rapidly developing. In the papermaking process: the defoaming agent for papermaking needs to have better degassing and defoaming performances, and also needs not to have adverse effects on the quality of finished paper, particularly the effect on the sizing agent effect. The main active components comprise alcohols, alcohol epoxide addition products, fatty acid (ester) and the like, and more used high-carbon alcohols and the like are emulsified into an O/W type water-based defoaming agent and a PEG series oil-based or non-oil-based defoaming agent, and the organic silicon defoaming agent is not suitable for being used; in the production of coated paper: the defoaming agents added in the coating process are: fatty acid esters, mixtures of fatty acid esters and polyethers, stearic acid amides and dispersions of fatty acids in mineral oils, and the like. In the treatment of circulating water and sewage in paper mill, defoaming agent is also added for defoaming, so that the defoaming agent can also be used for defoaming in paper-making sewage treatment, antifreezing solution and distillation system.
On the other hand, the production of papermaking defoaming agent is mostly put into the agitator tank that has heating function with several kinds of raw materials and stirs, through accomplish stirring work promptly with raw materials stirring, and there is certain impurity in the raw materials usually, therefore need carry out filter work to the defoaming agent after the stirring is accomplished, filter work can be accomplished to traditional defoaming agent agitator tank, but inconvenient change work that carries out filtering component, change process trouble very, but if filtering component in time changes, influence filterable effect and speed very easily, agitator tank that has now simultaneously mostly can only carry out stirring work, and can not be fine when the stirring cut the raw materials, thereby make the inefficiency very of stirring work, be not suitable for the high-speed production of modernization.
