The invention discloses a test method for measuring plastic concrete permeability coefficient. Six test pieces are manufactured; butter is mixed with coal ash or cement at the mass ratio of 1:2-2.5 to prepare a sealing material for sealing the test pieces and a die trial. The water pressure of a permeameter is added to 0.2 MP once, constant pressure is kept for 6 hours, and the water seepage height is taken by ten moieties by splitting the test pieces. The relative permeability coefficient of the test piece is calculated according to the following formula: Kr=aDm2/2TH. The average value of the relative permeability coefficients of the six test pieces is the permeability coefficient of the plastic concrete. The invention fills the blank of the plastic concrete test method, and effectively overcomes the problem that the test result in the mix proportion design of the existing impermeable wall plastic concrete can not truly reflect the practical impermeable ability, thereby better matching ...

The theoretical plate theory for fractionation is applied in purifying organic luminescent material to obtain high purity material. The organic luminescent material purifier includes one sample area for loading organic luminescent material to be purified; at least one theoretical plate area with several partitioning boards for purifying organic luminescent material; and at least one collecting area for collecting the purified material. The material with high purity can improve the produced organic luminescent element and facilitate operation.
