Description
Technical field
The present invention relates to a kind of method of utilizing the coarse tall oil separated and refined slag modification to produce concrete admixture.
Background technology
Thick tall oil is one of byproduct of kraft pine pulp mill, though the composition variation range is bigger, but main content that it is generally acknowledged thick tall oil is resinous acid (having another name called sylvic acid), lipid acid, with a small amount of neutral substance and make oil have dark-coloured oxide compound, be widely used in making soap, lubricant, flotation agent, sizing agent, emulsifying agent, caking agent and paint, printing ink industry etc.
In kraft process, grease in the timber and resinous principle owing to the effect of alkali becomes soap, are dissolved in the black liquor, and neutral oil also is drawn out of and is dissolved in the soap lye simultaneously, Here it is sulfate soap.When black liquor was concentrated to finite concentration, sulfate soap just floated over above the black liquor.The sulfate soap of separating is the chocolate semi-fluid, the oil slick of oil-containing 50～55%wt, with saponified after the storagetank standing separation, and washings (with caustic soda, saltcake, salt or the like preparation) is sent to rinse bath together, alkaline washings can remove effectively saponified in 60～80% lignin and about 50% fiber and impurity.Washed saponified in the rinse bath with steam direct heating to 70 ℃, be sent to the acidifying system again, decompose with acid (sulfuric acid, nitric acid or hydrochloric acid etc. all can), saponified and sour after reacting in the reactor, resolve into components such as thick tall oil, lignin, fiber and gypsum, discharge H simultaneously
2S and CO
2Gas, these gases are sent to washer and wash, then the mixture after the acidifying is sent to subsider separator standing sedimentation, because thick tall oil and xylogen density difference are little, separate fully than difficulty, collect the upper strata oil reservoir and can obtain the higher tall oil of purity, also be referred to as tall oil or Tall oil or Yatall MA, tall oil mainly is the mixture by resinous acid, lipid acid, neutrals and impurity.The content of each composition is different because of the difference of seeds, weather, the age of tree, conditions of cooking, separation condition.Thick tall oil of part and xylogen are then contained in the middle layer of separating, because thick tall oil and lignin separation be difficulty, general enterprise separates periphery is sold in the back with very low price little chemical enterprise with this part, reclaim wherein remaining oil, if amount is few, then generally go out of use as rubbish, wasted resource, economic benefit is low.Orlop is a spent acid in three layers, after the separation, it is delivered to the spent acid groove, waits to add behind the alkali and uses for wash crude sulfate soap next time.
Air entrapment agent was applied to concrete existing more than 70 year.Air entrapment agent is a kind of tensio-active agent, can introduce many smallly and independent distribution is stable and lockedin air space in the concrete whipping process, plays dispersed and wettability effect, thereby improves concrete workability, raising freeze-thaw-weather resistance and anti-permeability performance.Bubble structure in the concrete directly influences workability and freeze-thaw-weather resistance.The bubble that the high-quality air entrapment agent is introduced is spherical in shape, about 20～200 μ m of diameter, and spread ratio is less than 200 μ m.Usually, the concrete that starting material and water cement ratio are identical, air content is about 1.5% when mixing air entrapment agent, and number of freezing and thawing has only 15～25 times; And mix the concrete of high-quality air entrapment agent, and when aggregate size is 20～80mm, air content 3%～6% o'clock, number of freezing and thawing can reach more than 200 times.Micro-bubble plays lubrication as ball, its absorption again once more after also isolated water mud pellet disperses effectively, and cut off capillary channel in the maturing, thus improved concrete workability, improve pumpability.In addition, bleed type water reducer can also further improve the water-reducing rate of concrete or mortar, reduces water cement ratio, remedy loss of strength and reduce the slump through the time loss.
The high-quality air entrapment agent can not only with compound uses such as multiple water reducer, frostproofer, pumping agent, and can and silica flour, flyash, ground slag, zeolite powder, swelling agent etc. are common uses, reach the further purpose of improving concrete performance. present domestic air entrapment agent commonly used is broadly divided into two types:
1. rosin based air entrapment agent
The rosin based air entrapment agent mainly is that sylvic acid saponification thing and rosin become the ester class with condensation reactions at a certain temperature such as phenol, sulfuric acid, sodium hydroxide, become than macromole through further polycondensation, pass through sodium-hydroxide treatment again, become the polycondensate of sodium salt, i.e. colophonium pyrolytic polymer.This class air entrapment agent existing more than 70 year so far is widely used in pavement concrete, water conservancy project and polyacrylonitrile fiber concrete and some have the concrete works of antiseepage, freeze proof requirement.It is to improving concrete workability, water-retentivity, and it is remarkable to improve the weather resistance effect.But be difficult to dissolving, need heat, add alkali during use,, also need improve with shortcomings such as other admixture consistencies are relatively poor.
2. non-rosin based tensio-active agent
From the sixties in 20th century, begin development and use non-rosin based air entrapment agent, as air entrapment agents such as sulfo group benzene sulfonic acid sodium salt, OP emulsifying agent, soap English powder, modified form anion surfactant 801,901A.The chemical structure characteristics of this class air entrapment agent are to introduce hydrophilic group on the nonionic surfactant-based plinth, make it soluble in water, and whipability is good, and foam is thinner, and can be compound with other kind admixtures preferably, successfully are applied in the concrete for hydraulic structure engineering.Aniorfic surfactant such as sodium alkyl benzene sulfonate, soluble in water, easily bubble, but its foam is bigger, easily disappear.In addition, the oxyethylene affixture of nonionic surface active agent alkylphenol the bleed effect is also arranged, but price is higher.With three withered saponin(es is the air entrapment agent of main component, also is applied in some engineerings in recent years.
Use more air entrapment agent mostly to be some anion surfactants in the Chinese commodity concrete construction, principal item has rosined soap, colophonium pyrolytic polymer air entrapment agent, three obedient saponin(e air entrapment agents (is raw material with the plant Chinese honey locust), alkylsulfonate (mainly being sodium lauryl sulphate), sodium alkyl benzene sulfonate and polyethers and kinds of surface promoting agent mixture, acrylic acid epoxy ester resin synthesis type air entrapment agent, polysiloxane concrete air-entrainer, high-performance sulfuric ester salt concrete air-entrainer and polycarboxylic acid concrete air-entrainer etc.
Alkali lignin and sulfonate thereof are a kind of anion surfactants, have diminishing, slow setting, foaming and dissemination, obtain using more widely in commerical ready-mixed concrete, pump concrete, water-proof concrete, concrete for hydraulic structure, road concrete, high-strength concrete (needing the control volume) as ordinary water-reducing agent usually.
Residue acid number behind the thick tall oil separation and purification is 120～140mg KOH/g, and resinous acid content is 44%～50%, and fatty acid content is 25%～30%, and unsaponifiable matter content is 11～15%, and alkali lignin content is 5.0%～8.0%.Utilize behind the thick tall oil separation and purification residue modification to produce concrete admixture and realized that not only thick tall oil oil refining separates the comprehensive utilization of back residue resource, solve the feedstream pollution problem of becoming estranged simultaneously again, and can reduce production costs, improve profit.The coarse tall oil separated and refined slag that utilization contains alkali lignin prepares concrete admixture; it is abundanter to have raw material sources; cheap and product does not need process to separate the characteristics that just can directly use; in actual production, have broad application prospects; to promoting energy-saving and emission-reduction and resource to make full use of, protection environment and realization Sustainable development have than important social and economic implications.
