Description
Technical field
The utility model relates to Ceramic Tiles water absorption rate determination techniques, and in particular to a kind of fully-automatic ceramic brick boiling process water suction
Rate chamber.
Background technique
Ceramic Tiles are one of most important most common decorating and renovating materials, the main performance of Ceramic Tiles include presentation quality,
Dimensional discrepancy, water absorption rate, breakdown strength, wearability and anti-glaze fragility etc., wherein water absorption rate is most important parameter, is to determine pottery
The important indicator of ceramic tile quality good or not.
When usual water absorption rate refers to that Ceramic Tiles unit mass reaches saturation water suction under drying regime, the quality hundred of moisture is absorbed
Divide rate.The foundation that national standard GB/T4100-2015 " Ceramic Tiles " uses water absorption rate to classify as Ceramic Tiles.
The test method of existing Ceramic Tiles water absorption rate mainly has national standard GB/T3810.3-2016 " Ceramic Tiles test method
3 parts: the measurement of water absorption rate, apparent porosity, apparent relative density and bulk density " defined boiling process and vacuum method.Above-mentioned mark
Standard clearly states boiling process suitable for Ceramic Tiles classification and the description of product, and vacuum method is suitable for apparent porosity, apparent relative density
With the water absorption rate measurement in addition to classification.The method for carrying out product classification and quality inspection to Ceramic Tiles should use boiling process.
National standard GB/T3810.3-2016 provides as follows ceramic tile boiling process test process: brick is vertically placed on to Sheng
Have in the heating device of deionized water, brick is made to be not in contact with each other, from the water surface at least 5cm, lower part should be maintained far from the bottom on the top of brick
At least distance of 5cm, and should all keep the water surface to be higher than brick top surface 5cm or more in entire test.It heats water to boiling and protects
Fluidized state 2h is held, heat source is then cut off.There are two types of operations below: it is cooled to room temperature first, being completely sunk in the water brick, and
4 ± 0.25h is impregnated at room temperature；Second, can also after keeping fluidized state 2h, under room temperature deionized water or refrigerator will
Sample is cooled to room temperature, and then impregnates 4 ± 0.25h at room temperature.Finally, requiring to be soaked with one piece and the chamois leather wrung out is put
Every piece of surface turned is lightly dried on platform, and surface water is trippingly wiped using chamois leather for concave-convex or card-cut surface
Point, it then weighs, records the weighing result of every piece of sample, water absorption rate E=(m1-m0)/m0× 100%, wherein m0Indicate ceramics
Dry mass after brick drying, m1Quality after indicating Ceramic Tiles water suction.
Above-mentioned national standard has only simply specified test procedure, and the corresponding test apparatus used is not suggested.Currently, people
Electromagnetic oven etc. is mostly used to boil Ceramic Tiles greatly, and complete ceramics in such a way that manual time-keeping plus cooling water are cooling
The boiling test of brick.Above-mentioned test process whole process needs are artificial on duty, first have to when artificial observation boils, set 2h after boiling
Be then shut off test apparatus, then give sample cooling, finally reset the soaking at room temperature time, although workload is little, it is time-consuming compared with
It is long, it greatly affected the working efficiency of testing crew, since different step interval time is longer, testing crew is very in practice
The problem of hardly possible guards always on side, often will appear too long boiling time or long soaking time causes test result inaccurate.
In conclusion the test apparatus of existing Ceramic Tiles boiling test, greatly affected the test efficiency of testing crew,
And easily lead to test result inaccuracy.
