Abstract
The invention provides a defoaming agent for printing and dyeing wastewater. The defoaming agent is obtained by stirring and emulsifying a mixture which consists of simethicone, monoglyceric stearate and sodium carboxymethylcellulose and serves as an active substance and a non-ionized surfactant, a dispersing agent and a solvent carrier which serve as auxiliary materials. The mass ratio of the simethicone, the monoglyceric stearate to the sodium carboxymethylcellulose is (1-5): (1-3): (1-3); the non-ionized surfactant is a span type surfactant or a tween type surfactant; the dispersing agent is hydrophobic silica; the solvent carrier is water.
Description
Technical field
The invention belongs to water conditioner field, be specifically related to a kind of defoamer, relate in particular to a kind of defoamer for dyeing waste water.
Background technology
Dyeing waste water is dyeing residual liquid, the rinse water that fabric produces in dyeing or stamp process, and pre-treatment (as: scouring of wool, silk retting, destarch etc.), the composite waste of the waste water that rear arrangement produces.Due to the dyestuff, auxiliary agent that use need not, in the factory effluent of each factory discharge, pollutent character and quantity are also different, textile printing and dyeing wastewater can be divided into following a few class: woolen industry waste water, cotton industry waste water, silk textile industry waste water and flax spinning industry waste water.This requirement to cotton spinning printing and dyeing defoamer is very high, and cotton spinning dyeing waste water belongs to compared with the waste water of refractory reason.
Along with the development of printing and dyeing industry, increasing foamer (as washing composition, detergent, permeate agent, scouring agent, levelling agent etc.) is added in each procedure of dyeing and finishing processing, the effects such as this foamer can soak in each operation, washing, dispersion, level dyeing, bring good treatment effect to dyeing and finishing processing, but the dyeing and finishing process of fabric is the process of fabric cyclic motion in gas-liquid two-phase, foamer can produce a large amount of foams.The generation of a large amount of foams can take processing space, reduces working (machining) efficiency, increases the consumption of auxiliary agent and resource, causes the generation of waster, even makes to produce normally to carry out, and therefore must eliminate foam with defoamer, ensures normally carrying out of producing.
According to the difference of froth breaking actives, defoamer can be divided into animal oil type, mineral oil origin, polyether-type and 4 kinds of main Types of organosilicon, most widely used with organosilicon emulsion defoaming agents.Froth breaking actives mainly comprises vegetable and animals oils, mineral oil, fatty acid amide, fatty acid ester, fatty acid metal soap, phosphoric acid ester, silicone oil, silicon polyethers, ethylene oxide propylene oxide segmented copolymer, saturated and unsaturated fatty acids, alpha-sulfonated fatty acid, higher alcohols etc.
Summary of the invention
The invention provides a kind of defoamer of the high temperature resistant highly basic for treatment of dyeing wastewater, take built reactive material as main froth breaking material.
For achieving the above object, the present invention adopts following technical scheme:
A kind of dyeing waste water defoamer, take the mixture of dimethyl silicone oil, stearic acid monoglycerides and Xylo-Mucine as active substance, is aided with emulsifying agent, dispersion agent and solvent carrier, at high temperature after stirring, emulsification, obtains.
In the preferred technical scheme of the present invention, described dimethyl silicone oil, stearic acid monoglycerides and Xylo-Mucine be (1 ~ 5) in mass ratio: (1 ~ 3): (1 ~ 3).
In the preferred technical scheme of the present invention, described nonionic emulsifying agent is this dish class tensio-active agent or Tweens tensio-active agent.
In the preferred technical scheme of the present invention, described dispersion agent is water drain silica.
In the preferred technical scheme of the present invention, described solvent carrier is water.
The effect of emulsifying agent is to make activeconstituents to be dispersed into small-particle, is convenient to be dispersed in water, and improves infiltration and the diffusibility of defoamer, better plays froth breaking, presses down bubble effect and make defoamer be easy to infiltrate between foam, and come in the diffusion of foam surface rete.In the preferred technical scheme of the present invention, described emulsifying agent is the one in this dish-40, this dish-60, tween 20, Tween-60, tween-80.
The effect of solvent is the combination with bubbling system, makes activeconstituents be easy to be distributed in bubbling system, and both are combined, and the surface tension of itself is low, contributes to press down bubble, and can reduce costs.In the preferred technical scheme of the present invention, described solvent is water.
The effect of dispersion agent is the surface tension reducing between defoamer suspension and processed liquid, makes defoamer spread in fluid surface with form of film.In the preferred technical scheme of the present invention, described tensio-active agent is water drain silica.
Based on technique scheme, defoamer provided by the invention divides composed of the following components by quality:
Than prior art, the beneficial effect of defoamer provided by the invention:
(1) defoamer provided by the invention good dispersity in aqueous systems, antifoaming speed is fast, but the bubble time is long, except available in printing and dyeing, much needs the occasion of froth breaking all must be able to use at other, is a kind of universal industrial defoaming agent;
(2) defoamer provided by the invention has under high temperature highly basic that anti-high-shear, consumption are few, not breakdown of emulsion, the feature of floating oil not, and froth breaking power is stronger than normal temperature on the contrary;
(3) BOD on waste water, COD and the TOD of defoamer provided by the invention almost do not affect.
