Description
Technical field
The present invention relates to a kind of water-intake rate determinator and method thereof, is the apparatus and method that are used for measuring the water-intake rate of a kind of drought-resistant material and water-loss reducer specifically.
Background technology
The macromolecule water-loss reducer is the strong especially new functional macromolecule material of a kind of water-intake capacity, is being widely used aspect physiological hygiene articles for use, agriculture and garden, medicine and the building.Therefore the height of macromolecule water-loss reducer water-intake rate directly influences its application aspect the physiological hygiene articles for use, to the evaluation of the water absorbing properties particular importance that seems.Water-loss reducer is paid much attention at synthetic and preparation this respect, has 85 more than with regard to various patents of invention of having authorized, and at present the mensuration of water-loss reducer water-intake rate is not had systematic research.
The drought-resistant material generally is wrapped in the surface of fertiliser granulates by the macromolecule water-loss reducer; The macromolecule water-loss reducer can play the effect of preserve moisture and fertility; But the water-intake rate of water-loss reducer and inorganic salt concentration have very big relation; When in water, dissolving the formation ion along with salt, the water retaining function of water-loss reducer significantly descends.The water absorption course of drought-resistant water-intake rate is exactly a dynamic process, and therefore common methods such as mesh bag filtration method just can't obtain correct result when measuring the water-intake rate of drought-resistant material.
The method that macromolecule water uptake property resin is measured water-intake rate at present mainly contains natural filtration method (mesh bag method), flow method, centrifugal separation, paper bag method, slice method, graduated cylinder method and capillary tube technique etc.Natural filtration method (mesh bag method) mainly is that water-loss reducer is put into big water gaging, wait to be swelling to the suction saturated after, with the method for screen cloth with remaining water filtration.General using 200 purpose sieve aperture elimination moisture content, the method that water-loss reducer suction back weight increases is confirmed the water-intake capacity of water-loss reducer.The method is fairly simple, in practical operation, finds, the mesh bag method also is easy to generate error in measuring process, mainly is that the water-loss reducer suction needs the regular hour, and can not dynamically observes the variation of water-loss reducer water absorbing properties.Secondly, the mesh bag method can not be used for measuring the suction multiple of drought-resistant, mainly is that the nutrient ion in the fertilizer runs off from mesh bag with water, thereby can't judges the weight of suction.
Capillary tube technique; Be exactly that water-loss reducer utilizes the effect of capillarity attraction that moisture content is absorbed; Observe the variation of water volume in the kapillary, the defective of this assay method is that diameter capillaceous is less, and the mesh in the Buchner funnel is generally used 200 orders; The water-loss reducer that absorbs moisture content partly is easy to stop up capillary canal, forms fractional wettability.Measure moisture like this and also can cause bigger error.
Summary of the invention
The object of the invention is not enough and design to natural filtration method (mesh bag method) said apparatus and method; A kind of drought-resistant material water-intake rate determinator and method are provided; Solve existing determinator and can't accurately measure the method for drought-resistant material water-intake rate, can not dynamic measurement drought-resistant material in the device of water-loss reducer water-intake rate.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of mensuration drought-resistant material water-intake rate determinator; Comprise iron stand, base buret, acid buret; It is characterized in that: fixedly acid buret and base buret respectively in the iron stand both sides; Described acid buret and base buret link together through transparent band tubing, on the said base buret conical hopper are set.
Described determinator is characterized in that: said acid buret and base buret are fixed on the iron stand with the mode perpendicular to ground, and said acid buret and base buret are positioned at same plane.
Described determinator is characterized in that: the shank of said conical hopper inserts in the said base buret, and said conical hopper shank is with the inwall of soft rubber pipe and base buret port and fits, and scribbles the vaseline sealing on the said soft rubber pipe.
Described determinator is characterized in that: the capacity of said acid buret and said base buret is 50 milliliters.
Described determinator is measured the method for compound fertilizer water-intake rate, it is characterized in that, comprises the following steps:
(1) is ready to used iron stand, acid buret, base buret, conical hopper, transparent band tubing, soft rubber pipe, filter paper, vaseline, drought-resistant material, water-loss reducer and distilled water;
(2) acid buret and base buret are fixed on the iron stand; And the acid buret top is a little more than the top of base buret; Conical hopper is inserted in the base buret; The conical hopper shank is lived with the soft rubber pipe box, is coated with a little vaseline on the soft rubber pipe and reaches sealing effectiveness, and filter paper is converted into taper and is close to the funnel inboard;
(3) distilled water adds from funnel, and regulates liquid level, makes the interior 0 scale liquid level of acid buret equal with conical hopper bottom liquid level;
(4), pour the drought-resistant material into the conical hopper bottom with ten thousand/balance weighing drought-resistant material;
(5) raise the about 20-30 of acid buret centimetre;
(6) treat that liquid level medium drought resistant compound fertilizer is all wetting after; Regulate the acid buret height; Make the base buret liquid level still remain on the conical hopper bottom, close the piston of acid buret, the scale of record acid buret; Through the water absorbing capacity of the drought-resistant material that records, can measure the water-intake rate of water-loss reducer.
Used determinator is simple and easy to assembling, just can assemble in ordinary laboratory.Biggest advantage is to dynamic observe the variation of drought-resistant material and water-loss reducer water-intake rate; Composite fertilizer for macromolecule water-loss reducer parcel; Salinity has very big influence in its water absorbing properties and the composite fertilizer, and at 0.1% o'clock, its water absorbing properties just significantly descended like salt concentration.Described this device can dynamically be observed the variation of drought-resistant material water absorbing capacity, and when salinity overflowed or dissolve, its volume that absorbs moisture content can diminish.
