Embodiment is being to implement under the prerequisite with the technical solution of the present invention, has provided detailed embodiment and concrete operating process, and embodiment will help to understand the present invention, but protection scope of the present invention is not limited to following embodiment.
Method therefor is ordinary method if no special instructions among the following embodiment.
The high integrity container of embodiment 1-6 is as shown in table 1 with composition of raw materials and the preparation technology parameter of sealing material and comparative example:
The high integrity container of table 1 embodiment 1-6 is with composition of raw materials and the preparation technology parameter of sealing material and comparative example
Prepare the high integrity container of embodiment 1-6 with the method for sealing material and comparative example, can may further comprise the steps:
1) takes by weighing cement, sand, water reducer, swelling agent by the weight proportion in the table 1, it is mixed;
2) compound in the step 1) is added in the mechanical mortar mixer, start stirrer, (addition sequence of polymer emulsion, water and solidifying agent is variable to add polymer emulsion, water and solidifying agent according to quantity successively, but polymer emulsion and solidifying agent can not add simultaneously), stirring velocity is 140-285rpm, churning time should be no less than 3min, makes to stir back degree of mobilization 〉=130mm, reaches from the levelling effect.Obtain high integrity container perfusion sealing material thus.
Performance Detection
, the high integrity container of the present invention is detected with sealing material with reference to the method for testing performance among the DLT5126-2001 " polymer-modified cement mortar testing regulation " with sealing material specified performance index request according to the high integrity container shown in the table 2.
The high integrity container of table 2 sealing material specified performance index request
1 listed material tests result is as shown in table 3 for his-and-hers watches.
The high integrity container of table 3 embodiment 1-6 is poured into the performance test results with sealing material and comparative example
Table 3 data presentation: in the comparative example 1, undesirable because of the type of polymer of using, and do not add solidifying agent, cause radiation resistance defective, the loss of γ irradiation intensity is up to 30%, and physical strength, freeze-thaw resistance, sulphate attack simultaneously also descends to some extent than embodiment 1; Because not using swelling agent, cause contraction too big in the comparative example 2, do not meet≤300 * 10
-6The m/m requirement; Do not have water reducer in the comparative example 3, water consumption will increase, cause degree of compactness descend (show on the performance nitrogen gas permeability can be defective and mechanical strength index, freeze-thaw resistance, sulphate attack also than embodiment 1 corresponding decline).And the high integrity container of the inventive method preparation all meets index request with sealing material, has high compact (with reference to nitrogen gas permeability and infiltration index), high-adhesion (with reference to the drawing bonding strength), high-strength (with reference to the physical strength index), anti-(with reference to contraction of indices), high anti-irradiation (with reference to anti-γ radiation property index) and the high-durability energy (with reference to freeze-thaw resistance and sulphate attack index) of shrinking.And have high fluidity (with reference to stirring back degree of mobilization index), can satisfy the control requirement of material instillation process.
In table 2 and the table 3, anti-γ radiation property index, freeze-thaw resistance and several indexs of sulphate attack are that sample accelerates experimental result.Table 3 data also satisfy simultaneously at material under the prerequisite of physicals and physical strength index, are used for the integral sealing container with reference to table 2 standard by the sealing material of calculating the preparation of explanation the inventive method, and service life can reach 300 years.And comparative example 1 anti-γ radiation property index exceeding standard, not anti-irradiation, As time goes on, the irradiation of nuke rubbish can slowly corrode sealing material, causes nuclear leakage; Comparative example 2 contraction of indices are too big, and cracking phenomena appears in sealing material, and stopping property lost efficacy; Comparative example 3 nitrogen gas permeability indexs are defective, and degree of compactness descends, and nuke rubbish can ooze out, and can not guarantee 300 years.
As seen, sealing material of the present invention and high integrity container are complementary with mechanical performance of concrete, advantage with high-adhesion energy, radioresistens particle irradiation, service life can reach 300 years, adapt to environmental protection concept, to play a great role in nuclear waste disposal, building structure reparation field, have a extensive future.
