Embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of building block insulation property testing device for heat preservation, comprise heating arrangement 1, temperature testing device 2, building block test casing 3, computer data processing unit (not indicating in figure), described building block test casing 3 left sides are provided with heating arrangement 1, described building block test casing 3 one sides are provided with temperature testing device 2, described temperature testing device 2 and computer data processing unit communication connection, in described building block test casing 3, place test building block 4, described temperature testing device 2 is connected with described test building block 4 points for measuring temperature.
As preferably, described building block test casing 3 is provided with two cavitys, can test two kinds of building blocks simultaneously or test identical two groups of building blocks contrasting.
As preferably, between described heating arrangement 1 and described test building block 4, glass baffle plate 5 is installed, can play the effect of even conduction heat.
As preferably, between described test building block 4, be provided with insulation liner plate 6, can play insulation effect.
Specific embodiment of the utility model is, test building block 4 is positioned in building block test casing 3, test building block hot side 7, huyashi-chuuka (cold chinese-style noodles) 8 and inside cavity side 9 are connected with temperature testing device respectively, heating arrangement to test block surfaces heating 24h after the cooling 24h of normal temperature again, test is not inserted the building block of rice straw board concrete porous brick, inserts rice straw plate and is inserted the Changing Pattern of concrete perforated brick building block hot side, huyashi-chuuka (cold chinese-style noodles) and the inside cavity side medial temperature of rice straw phase change plate respectively.
As shown in Figure 2, in heating process, after insertion rice straw plate and rice straw phase change plate, concrete perforated brick building block hot-face temperature slightly reduces; In temperature-fall period, insert rice straw plate close with former concrete perforated brick building block hot-face temperature pace of change, and insert after rice straw phase change plate temperature, underspeed and slightly reduce, during 48h, hot-face temperature is also slightly high, inserts as seen rice straw plate and rice straw phase change plate and can to a certain degree delay the transmission of heat.
As shown in Figure 3, in heating process, after insertion rice straw plate and rice straw phase change plate, concrete perforated brick building block huyashi-chuuka (cold chinese-style noodles) temperature increases slowly, and huyashi-chuuka (cold chinese-style noodles) temperature is all lower than former concrete segment.Rice straw plate is because coefficient of heat conductivity is lower, and can store certain heat, make the transmission of heat become slow, thereby insert the increase of rice straw board concrete building block huyashi-chuuka (cold chinese-style noodles) temperature slowly, huyashi-chuuka (cold chinese-style noodles) temperature also more former concrete perforated brick building block is low, insert the increase of rice straw phase change plate concrete perforated brick building block huyashi-chuuka (cold chinese-style noodles) temperature more slow, huyashi-chuuka (cold chinese-style noodles) temperature is also minimum.Concrete segment hot-face temperature curve is as Fig. 2, hot-face temperature is 80 ℃ of left and right, huyashi-chuuka (cold chinese-style noodles) initial temperature is under 14.5 ℃ of left and right conditions, inserting rice straw phase change plate concrete perforated brick building block huyashi-chuuka (cold chinese-style noodles), to reach time of 25 ℃ be 17h, than the concrete perforated brick building block and the former concrete segment that insert rice straw plate, extended respectively 6.5h and 9h; And, when being heated, continuing to keep after 5h and 8h, its huyashi-chuuka (cold chinese-style noodles) temperature only rises respectively 1.4 ℃ and 3.9 ℃, and the temperature difference of huyashi-chuuka (cold chinese-style noodles) and hot side is respectively 64.1 ℃ and 61.6 ℃; During heating 9h, the temperature difference is maximum, and the more former concrete segment of huyashi-chuuka (cold chinese-style noodles) temperature is low 6.9 ℃, inserts rice straw board concrete brick low 4.9 ℃.Visible when heating, phase-change material has absorbed a large amount of heats in the process of constantly fusing, and making to insert rice straw phase change plate concrete brick huyashi-chuuka (cold chinese-style noodles) temperature increases slowly; In temperature-fall period, insert rice straw plate close with former concrete segment hot-face temperature pace of change, and temperature reduces slowly after inserting rice straw phase change plate, in the process that phase-change material constantly solidifies, emitted a large amount of heats, make to insert rice straw phase change plate concrete segment huyashi-chuuka (cold chinese-style noodles) temperature and reduce slowly.During cooling rear 48h, the more former concrete brick of its huyashi-chuuka (cold chinese-style noodles) temperature is high 2.3 ℃, inserts rice straw board concrete brick low 2.5 ℃.
As shown in Figure 4, in heating process, after insertion rice straw plate and rice straw phase change plate, temperature more former concrete segment in concrete segment side increases slowly, and side temperature is also lower.Wherein insert rice straw phase change plate temperature variation the slowest, side temperature is minimum.Building block hot side is heated as Fig. 2, side initial temperature is under 14.5 ℃ of left and right conditions, inserting rice straw phase change plate concrete brick body of wall medial surface temperature, to reach time of 25 ℃ be 20.5h, than the concrete brick and the former concrete brick that insert rice straw plate, extended respectively 8h and 10h; And, when being heated, continuing to keep after 5h and 8h, its huyashi-chuuka (cold chinese-style noodles) temperature only rises respectively 0.9 ℃ and 3.8 ℃; Heating during 10h the temperature difference maximum, survey the more former concrete segment of surface temperature low 4.2 ℃, insert the building block of rice straw board concrete low 3.6 ℃; In temperature-fall period, inserting rice straw plate and former concrete segment side temperature underspeeds close, insert rice straw phase change plate concrete segment huyashi-chuuka (cold chinese-style noodles) temperature and reduce slowly, during 48h, the more former concrete brick of its huyashi-chuuka (cold chinese-style noodles) temperature is high 0.4 ℃, inserts rice straw board concrete brick high 0.6 ℃.
Sum up: according to concrete segment heating surface temperature changing regularity, concrete segment huyashi-chuuka (cold chinese-style noodles) temperature changing regularity, inside cavity side temperature changing regularity: the speed of the highest under identical heating condition, minimum temperature, temperature increase is, arrive the asynchronism(-nization) etc. of uniform temp.Can judge: 3 kinds of sample heat preservation and insulations are sequentially: building block (inserting rice straw phase change plate) > building block (inserting rice straw plate) the former concrete perforated brick building block of >.
To sum up, a kind of building block insulation property testing device for heat preservation of the utility model can be measured the heat-insulating property of two kinds of different insulation blocks or identical building block, carries out comparative study.Method of testing is simple, quick, accurate, evaluates fast the quality of building block heat-insulating property, does not destroy building block, reacts really the heat-insulating property of building block, for insulation blocks designs, the research and development of material provide method easily.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modifications that are equal to replacement or make according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, within all should being included in the desired interest field of the utility model.
