Example Embodiment

[0029] Example 1

[0030] like Figure 1-2 As shown in the figure, a method for measuring the coverage rate of a composite phase change material is carried out as follows: Step 1: Sampling: Weigh the composite phase change material for testing, and record it as mass M0; Step 2: Prepare a test sample: take Step 1: Obtain the composite phase change material and press it into a cylindrical shape, wrap it with degreased filter paper, and obtain a test sample 10; Step 3: Weigh once: weigh the test sample 10 obtained in step 2, and record it as mass M1; Step 4: Extract the phase Change core material: use the leaching method to remove the phase change core material in the test sample; step 5: secondary weighing: weigh the test sample 10 processed in step 4 and record it as mass M2; step 6: calculate: use the formula (M1 -M2) / M0, the coverage of test sample 10 is calculated.

[0034] Example 2

[0035] like Figure 1-3 As shown in the figure, a method for measuring the coverage ratio of a composite phase change material in this embodiment, the test process is the same as that in Embodiment 1, the difference is that a pretreatment step is also set before the step 1: rinse the composite phase change material, use To remove the phase change core material adhering to the surface of the composite phase change material.

[0036] In a method for measuring the coverage ratio of a composite phase change material in this embodiment, the composite phase change material is repeatedly washed by setting a pretreatment step before step 1 to remove the phase change core material adhering to the surface of the composite phase change material, The results of the measured coverage rate all come from the phase change core material coated inside the composite phase change material, so that the test results are more accurate. Composite phase change material, another gr...

Abstract

The invention relates to the field of building energy-saving detection technology, in particular to a method for measuring the coating rate of a composite phase change material, which is carried out as follows: step 1: sampling: weighing the composite phase change material for testing, and record it as mass M0; step 2: Preparing the test sample: the composite phase change material obtained in step1 is pressed into a cylindrical shape, wrap it up with the degreased filter paper to prepare a test sample; step 3: primary weighing: weighing the test sample obtained in step 1, and recording it asmass M1; step 4: extracting the phase change core material: removing the phase change core material in the test sample by the leaching method; step 5: secondary weighing: weighing the test sample process in step 4, and recording it as mass M2; step 6: calculating : using the formula (M1*M2)/M0, the coating rate of the test sample is calculated. The principle is simple and easy to understand, the equipment is easy to operate, the test is convenient and fast, the test cost is reduced, the test result is accurate, and the composite phase change material can be truly reflected as to its storage heat and temperature regulation performance.

Description

technical field [0001] The invention relates to the technical field of building energy-saving detection, in particular to a method for measuring the cladding ratio of a composite phase-change material. Background technique [0002] Phase change materials refer to substances that change the state of matter with temperature changes and can provide latent heat. When the temperature of a phase change material reaches its phase change temperature during the process of rising and falling in the ambient temperature, the phase change material will absorb or release heat, thereby affecting the environment. Due to the temperature change of the environment, pure phase change materials are prone to segregation in building energy-saving applications, so it is necessary to encapsulate or wrap the phase change materials to obtain composite phase change materials. The key performance of composite phase change materials is in the application The storage and release of heat and temperature ad...
