Abstract
The invention discloses a kind of electric toilet seat test standard analog excretas.Selection including the reference substance raw material and preparation process.Calcium carbonate and sodium alginate are the important raw material of two of which.By the selection and the preparation process that strictly control raw material, so that the stability of characteristics such as viscosity, uniformity, density, moisture content of standard analog excreta for preparing, uniform, consistency is good, the repeatability and stability that ensure that test result, so as to the clean-up performance of the electric toilet seat of evaluation of more objective.
Description
Technical field
Present invention design is related to a kind of selection of raw material of electric toilet seat test standard analog excreta and prepares work
Skill.
Background technology
Electric toilet seat refers to cleaning human body residual draining object by water by electric drive, can carry blowing, seat ring heating etc.
Single or multiple functions utensils (hereinafter referred to as " utensil ").Clean rate is an important finger of the electric toilet seat clean-up performance of evaluation
Mark indicates cleaning capacity with the percentage of removal slop.Existing national standard GB/T 23131《Electric toilet seat》Middle use
Weight method measures clean rate：Standard analog faecal samples are applied on load substrate first, weigh the gross mass W of substrate1,
After running cleaning procedure 1min, with blotting paper adsorption surface moisture, substrate is weighed again and remains the gross mass W of loaded article2, clearly
Clean rate calculation formula is as follows：
In formula：
C-clean rate, is expressed as a percentage；
Wo- transparent substrate quality, unit are gram (g)；
W1The gross mass of substrate and dirt load criteria sample before-flushing, unit are gram (g)；
W2The gross mass of-flushing metacoxal plate and remaining dirt load criteria sample, unit are gram (g).
Wherein, the preparation process of simulation faecal samples used is as follows：
A) the 100g calcium carbonate and 1g sodium alginates weighed pours into the same beaker, is stirred at same direction with glass bar
10min；
B) 0.2g methyl blues are weighed, are put into beaker, the distilled water of 76mL are injected thereto, with glass bar stir about
5min；
C) calcium carbonate stirred evenly and sodium alginate mixed-powder are put into a glass container, methyl blue solution is slow
Slowly it uniformly pours into glass container, is stirred with glass bar when pouring into, after liquid is poured into completely, at least with glass bar stirring
30min, until simulation slop color is uniform, surface is smooth.
Producing for standard analog excreta need to strictly control raw material and preparation process, to ensure to test in different laboratory
As a result consistency and repeatability reduce the uncertainty of test, to which science objectively reacts the spatter property of electric toilet seat
The quality of energy.
Calcium carbonate is commonly called as lime stone, marble, calcite, is a kind of inorganic compound, chemical formula CaCO3, there is heavy carbon
The variety classes such as sour calcium, precipitated calcium carbonate, powdered whiting density ratio precipitated calcium carbonate density weight, are prepared using physical method,
Whiteness is relatively low；Precipitated calcium carbonate is prepared using chemical method, and density is light, and whiteness is high, and grain size can be accomplished very thin.According to heavy
Calcium carbonate produces electric toilet seat and surveys tentative standard excreta, it may appear that is difficult to shape, the poor problem of viscosity.
Sodium alginate is the mixture of polyuronide, can be used as additive and is used for increasing vicidity, is widely used in food, spins
The making of fabric, cosmetics etc., sodium alginate are two kinds by two kinds of monomer compositions of mannuronic acid (M) and glucuronic acid (G)
The ratio of monomer is different, and performance is also different.High G/M than sodium alginate combined with calcium carbonate after the gelatinous mass hardness that is formed
It is big and more crisp, cause the standard analog excreta viscosity produced inadequate.
The committed step for preparing the standard analog excreta is that methyl blue solution is poured slowly into calcium carbonate and sodium alginate
Mixture after, be kept stirring at least 30 minutes.If stir speed (S.S.) is unstable during being somebody's turn to do, the standard analog prepared row can be caused
The viscosity for letting out object is inconsistent, to meet the requirement of experiment repeatability and consistency.
Invention content
The purpose of the present invention is to provide a kind of electric toilet seat test standard analog excretas, solve standard analog row
The bad problem of the stickiness of object, uniformity, consistency is let out, ensure that the repeatability and stability of test result, so as to
The clean-up performance of the electric toilet seat of evaluation of more objective.
In order to achieve the above objectives, the technical scheme is that：A kind of electricity toilet seat test standard analog excreta,
It is characterized in that, includes selection and preparation process two parts of raw material.
Further, a kind of electric toilet seat, which is tested, uses standard analog excreta, and the calcium carbonate in raw material selects 200 purposes light
Matter calcium carbonate.
Further, a kind of electric toilet seat, which is tested, uses standard analog excreta, and the sodium alginate in raw material selects low G/M ratios
Sodium alginate.
Further, a kind of electric toilet seat, which is tested, uses standard analog excreta, the control of the mixing speed in preparation process：
After methyl blue solution slowly pours into the mixture of calcium carbonate and sodium alginate, the stir speed (S.S.) for being kept stirring stick is certain, be 55~
60 revs/min.
Due to the adoption of the above technical scheme, the beneficial effects of the invention are as follows：
The present invention is using the precipitated calcium carbonate of 200 mesh as the one kind for making electric toilet seat test standard analog excreta
Raw material, overcomes that powdered whiting density is larger to cause obtained standard analog excreta stickiness inadequate, shapeless, character
With really differ larger problem.Meanwhile calcium carbonate selects 200 mesh, can make its conjugation higher with other raw materials, more accord with
Close truth.
The present invention using low G/M than sodium alginate, the stickiness of standard analog excreta that can be obtained meets the requirements.
After methyl blue solution slowly pours into the mixture of calcium carbonate and sodium alginate, stir speed (S.S.) keeps certain, can make every
The characteristic of secondary standard analog excreta obtained is consistent, and meets the requirement of repeatability, stability.
Description of the drawings
Fig. 1 is a kind of Comparability test data profile of embodiment of the present invention.
Specific implementation mode
Experimental method used in following embodiments is conventional method unless otherwise specified.
The materials, reagents and the like used in the following examples is commercially available unless otherwise specified.
Embodiment 1
A kind of electricity toilet seat test standard analog excreta, selected dispensing are as follows：The precipitated calcium carbonate powder of 200 mesh (divides
Analyse pure) 100g, low G/M than sodium alginate (analysis pure) 1g, methyl blue (analysis is pure) 0.2g, distilled water 76ml.
It configures according to the following steps：
1. the 100g calcium carbonate weighed and 1g sodium alginates are poured into the same beaker, stirred at same direction with glass bar
