Illustrate technical effect of the invention below with reference to specific experimental data:
One, the measurement of radon, drop radon performance and precipitation rate of radon is hindered:
1, radon efficiency test is hindered:
It makes a side length and is slightly less than the single side opening of plate side length and fill radon case, inside, which is placed, stablizes radon need, top of the box
It is provided with activated charcoal, cabinet side is set there are two opening, and opening installs snorkel, and snorkel is connected with Continuous Instrument for Radon,
To be monitored to internal radon consistence.Using experimental material sealed opening face, after precipitation rate of radon reaches and stablizes, to material table
Face precipitation rate of radon J is measured, and tests schematic diagram such as Fig. 1.
According to formula (1) obtain enclosure space volume be V, surface area and be in the confined space of s balance radon consistence reason
By calculated value Cmax:
Cmax=(J*S)/λ V (1)
λ is the decay coefficient 2.1*10 of radon in formula-6s-1.If the potentiality radon consistence in surrounding medium is C0, then pass through formula
(2) it calculates material and hinders radon efficiency etaHinder radon:
ηHinder radon=(C0-Cmax)/C0 (2)
ηHinder radonSize can the resistance radon effect to material evaluate.
2, radon efficiency test drops:
Using experiment one airtight cavity of board making, set in cavity side there are two opening, for inside cavity radon
The measurement of concentration.Cavity is placed in the small-sized radon chamber that a radon consistence can be adjusted, inside cavity and a continuous survey
The connection of radon instrument continuously measures the radon consistence of inside cavity after small radon indoor radon concentration and temperature and humidity reach and stablize,
Test schematic diagram such as Fig. 2.After inside cavity radon consistence is stablized, the available balance radon consistence in certain condition lower chamber
CIt surveys, it is C in radon indoor radon concentration0Under conditions of, drop radon efficiency eta drop radon can be obtained by formula (3):
ηRadon drops=(C0-CIt surveys)/C0 (3)
It is thick to the anti-radon plate of JDPI-05a type, normalizing operation production 1mm, it is the anti-radon material of JBT-21S type, hand-made
The drop radon effect of the cavity of the anti-radon material production of 2.7mm~3.5mm thickness JBT-21S type is evaluated, and wherein JDPI-05a type is anti-
Radon plate is in 2.25*106(Bq/m3) tested under the conditions of radon consistence, the standardization production anti-radon material of 1mm thickness JBT~21S type
And the hand-made anti-radon material of JBT-21S type is respectively in 1*104(Bq/m3)、2.19*106(Bq/m3) under the conditions of radon consistence into
Row test.
3, diffusion coefficient calculates
Know that C is surveyed at oneself, C0, housing surface product S, volume V, material thickness H, and the solubility factor of radon in the material is seen as
When 1, diffusion coefficient D can be obtained by formula (4):
As D/ λ H2When sufficiently large, formula (4) be can simplify as formula (5):
Substituting into experimental data can be obtained the diffusion coefficient D of experimental material.
Since the anti-radon plate of JDPI-05a type is a kind of composite material, the diffusion of radon in the material is not to be situated between in a certain kind
The process spread in matter, so it is nonsensical for solving diffusion coefficient herein.
The cavity of radon material production anti-for JBT-21S type, the spraying of material is complete by dedicated unit in practical projects
At, there is preferable guarantee in technique, thus it is anti-using the data measurement material that the 1mm thickness cavity made under the conditions of standard operation obtains
Radon ability.It is D=3.83*10 that diffusion coefficient can be calculated according to formula (5)-12(m2/s)。
4, test result
Efficient resistance radon material (embodiment 1) environmentally protective to JDPI-05a type, the environmentally protective efficient resistance radon material of JBT-21S type
The anti-radon ability of material (embodiment 1) two kinds of materials has carried out quantitative assessment, precipitation rate of radon under experimental conditions and in 3m*
Performance such as the following table 1 of two kinds of test materials in the indoor enclosed environment of 4m*5m:
The anti-radon performance of 1 test material of table
From the results, it was seen that test material hinders radon effect and drop radon excellent effect under experimental conditions, meet indoor drop
Radon requirement.
Two, the resistance of JDPI-05a type oxygen wet plate (embodiment 1) plus JBT-21S type oxygen material (glue) (embodiment 1) poison
