Background technology
Water reducer is indispensable material and the core technology manufacturing modern concrete.Fast development along with China's capital construction
And gradually the popularizing of commerical ready-mixed concrete, the demand of water reducer is increased year by year, at present, the market of China's water reducer product holds
Amount reaches nearly ten million ton.
The production of water reducer includes that mother solution produces and finished product compounds two main process, wherein, the quality of water reducer mother solution
It it is the deciding factor affecting end properties.On market, the water reducer mother solution of main flow includes polycarboxylic acids, sulfonated acetone formaldehyde condensation polymer
Thing, naphthalene sulfonic acid formaldehyde condensation polymer, the water-soluble polymer such as sulfamic acid phenolformaldehyde condensate and melamino-formaldehyde condensation polymer.
During water reducer factory continuous prodution, need water reducer mother solution and finished product are carried out performance detection, tradition
Detection method be by mixing concrete, measure water-reducing rate.But, there is a lot of drawback in the method: one is mixed concrete
Needing 3～5 people's cooperatings, labor intensity is big, poor working environment.The raw materials such as two is to consume a large amount of cement, sandstone, have tested
Finish and produce again substantial amounts of concrete rubbish and be difficult to process.Three is that testing result can be unstable because of material quality fluctuation.
The yield produced due to water reducer is huge, and human and material resources and Environmental costs that the problems referred to above cause are very important
's.It would therefore be highly desirable to develop the most feasible a kind of novel water reducer method for testing performance.
Summary of the invention
For prior art exist deficiency, the present invention provide a kind of simple viscosity detecting device being applicable to water reducer and
Its using method, uses this device can realize the quick detection of water reducer mother solution performance.Use the inspection of device of the present invention
Survey method has efficiently, environmental protection, high reliability.
The simple viscosity detecting device being applicable to water reducer of the present invention, its structure includes apparatus main body and outer layer jacket
Pipe；Outer layer sleeve is thermostatted water sleeve pipe；
Described apparatus main body is provided with reservoir 3 and packing groove 4, has middle siphunculus road to connect reservoir 3 and packing groove 4；In logical
Pipeline one end extension becomes charge door 1, and the other end is discharging opening, and discharge outlet is provided with discharge valve 7；Upper Fang Zhongtong at reservoir
Pipeline is provided with fluid level scale 2-1, is provided with lower fluid level scale 2-2 on the middle siphunculus of the centre of packing groove 4 and reservoir 3,
Middle siphunculus below packing groove 4 is provided with filler supporting plate 6.
It is placed with filler 5 in packing groove 4；
Thermostatted water sleeve pipe 8 wraps up reservoir 3 to packing groove 4 position；Thermostatted water sleeve pipe 8 is arranged over water outlet at reservoir 3
Mouthful, below packing groove 4, it is provided with water inlet.
Described filler 5 is divided into upper and lower two-layer, the particle size range of upper strata filler 5 5～10mm, the particle diameter of lower floor's filler 5
Scope is 2～5mm.
In principle, any absorption or the inert substance of chemical reaction is not occurred to can serve as filler with water reducer mother solution
5。

The test philosophy of apparatus of the present invention is: equipped with filler 5 granule of particular design in apparatus of the present invention packing groove 4, when
When sample is by packing groove 4, by the flow resistance by filler.The flow resistance that the sample of different viscosities is subject to is different,
Viscosity is the biggest, and flow resistance is the biggest, and the corresponding delivery time is the longest.Test obtains delivery time data, i.e. reflects tested
The viscosity of sample.
For taking into account mobility and discrimination, the described filler 5 voidage in packing groove 4 is 30～70%, suitably tests
Water reducer mother solution mass concentration scope 5～20%；
The definition of described filler 5 voidage is:
When filler 5 voidage is too low or water reducer mother liquid concentration is too high, sample poor fluidity in a device, during outflow
Between long, even can occur block packing groove 4 risk；Otherwise, when voidage is high or concentration is too low, device is to different viscosities sample
Discrimination can decline.
The production of water reducer mother solution is by polyreaction by monomer, obtains the mistake with the polymer of certain molecular weight
Journey.Both there are some researches show, its performance is played vital impact by the relative molecular mass of water reducer, typically at certain a part
In amount is interval, water reducer performance can reach optimum, and too high or too low molecular weight all can damage water reducer performance.Additionally, for
The water reducer sample of one fixed structure, under identical solution concentration, its solution viscosity can reflect molecular size range.In factory
Under the conditions of continuous prodution, formula for a product and production technology determine that, its maximum variable affecting properties of product is i.e. molecule
Whether amount reaches design load.For this situation, use the delivery time of apparatus of the present invention test water reducer sample, it is possible to table
Levy its molecular weight ranges whether having reached manufacturing technique requirent, then evaluate its performance the most qualified.
Apparatus of the present invention are through particular design, by plant bulk ratio reasonable in design, double-deck filler 5 structure and suitable
In filler 4 voidage and filler 5 granular size so that different viscosities routine water reducer mother solution product can be in apparatus of the present invention
The differentiation effect that middle acquisition is good, is particularly well-suited to its viscosity measurements.
When using this device, thermostatted water passes in and out from the intake-outlet of warm water sleeve pipe.
The using method of apparatus of the present invention is: first, is disposed vertically apparatus of the present invention, and thermostatted water sleeve pipe 8 bottom in and top out is led to
Enter the thermostatted water of 25 DEG C, close discharge valve 7；Then, detected sample is added from charge door 1 so that it is be full of packing groove 4 and storage
Liquid bath 3, liquid level is concordant with upper fluid level scale 2-1；Finally, open discharge valve 7, make detected sample naturally flow out, use the second
Table record liquid level is down to the time of lower fluid level scale 2-2 from upper fluid level scale 2-1, is the delivery time of this detection sample.
The concrete operation method that device of the present invention quickly detects water reducer mother solution performance in continuous prodution condition is:
1. selection standard certified products.Standard certified products should be that factory produces recently, through concrete water-reducing ratio experiment inspection
It is qualified to survey, and the equivalent of products more than 20 batches of same model uniformly mixes, and represents the average behavior water of factory's certified products
Flat.
Test detection sample and the solids content of standard certified products the most respectively.
3. dilution detection sample is with standard certified products to identical mass concentration, makes the mass concentration scope after dilution 5
～20%.
4. use this device to test detection sample and the delivery time of standard certified products respectively.
5. whether judge sample passes according to delivery time relative standard deviation values, " │ delivery time relative standard deviation values │
3.0% " time, it is determined that sample passes, " │ delivery time relative standard deviation values │ 3.0% ", it is determined that for failed sample, wherein:
