【摘要】：伴隨著我國(guó)經(jīng)濟(jì)的迅猛發(fā)展,能源問(wèn)題日益突出,節(jié)約能源已成為實(shí)現(xiàn)可持續(xù)發(fā)展的關(guān)鍵環(huán)節(jié)。08年以來(lái)我國(guó)建筑行業(yè)迎來(lái)了發(fā)展高峰,過(guò)多的高能耗建筑將使建筑能耗超越交通、工業(yè)等行業(yè)而最終居于社會(huì)能耗的首位,達(dá)到30%左右。圍護(hù)結(jié)構(gòu)的熱工性能差是建筑物高能耗的主要原因,因此,改善圍護(hù)結(jié)構(gòu)的熱工性能,是解決建筑物高能耗的主要途徑。燒結(jié)保溫空心砌塊作為新型墻體材料,具有防火、與建筑物同壽命、保溫性能好等優(yōu)良性質(zhì),是理想的新型墻體保溫材料。本文主要通過(guò)在實(shí)驗(yàn)室研究燒結(jié)保溫空心砌塊的性能,探索添加造孔劑對(duì)材料熱工性能的影響,通過(guò)實(shí)驗(yàn)室得出的結(jié)論聯(lián)合工廠實(shí)地生產(chǎn)29排孔加造孔劑燒結(jié)保溫空心砌塊,根據(jù)實(shí)際產(chǎn)品的力學(xué)及熱工性能,分析其在建筑物節(jié)能上應(yīng)用的可行性,最后將產(chǎn)品成功應(yīng)用于示范建筑上面,滿足建筑節(jié)能的標(biāo)準(zhǔn)。首先,對(duì)原料及造孔劑的物理化學(xué)性能進(jìn)行分析,結(jié)果表明:新疆頁(yè)巖的化學(xué)及礦物組成適宜制備燒結(jié)保溫空心砌塊,頁(yè)巖的燒成溫度范圍為850~1050℃,最佳燒成溫度為950℃;鋸末和污泥的燒矢量大,分別達(dá)到98%和50%,適合做為造孔劑使用。其次,向頁(yè)巖中加入不同比例的造孔劑制備燒結(jié)保溫空心砌塊,測(cè)試其抗壓強(qiáng)度、顯氣孔率、體積密度和熱工性能,結(jié)果表明:造孔劑摻量對(duì)于制品的性能有顯著的影響。隨著造孔劑摻量的增加,試樣的顯氣孔率、干燥收縮與燒成收縮、燒矢量逐漸增加,體積密度、抗壓強(qiáng)度逐漸減小。當(dāng)鋸末添量為6%時(shí)試樣成型順利,導(dǎo)熱系數(shù)為0.1901W/(m·k),相比純頁(yè)巖下降了57.87%,在保證材料強(qiáng)度的前提下,添加鋸末造孔劑可顯著的提升了材料的保溫性能;當(dāng)污泥添量為15%時(shí)試樣成型順利,導(dǎo)熱系數(shù)為0.2031 W/(m·k),相比純頁(yè)巖下降了下降了54.99%,在保證材料強(qiáng)度的前提下,添加污泥造孔劑可顯著的提升了材料的保溫性能。綜合考慮兩種造孔劑的性能后,優(yōu)選出鋸末作為前期工廠試驗(yàn)造孔劑。首先,針對(duì)示范生產(chǎn)線的實(shí)際生產(chǎn)情況,對(duì)生產(chǎn)線生產(chǎn)工藝進(jìn)行優(yōu)化調(diào)整,提高生產(chǎn)效率,加大產(chǎn)能。其次,制備出29排孔加鋸末燒結(jié)頁(yè)巖保溫空心砌塊,并測(cè)試其力學(xué)性能、砌塊和砌體熱工性能,結(jié)果表明:加鋸末29排孔燒結(jié)頁(yè)巖保溫空心砌塊的抗壓強(qiáng)度等級(jí)達(dá)到MU10,符合國(guó)家標(biāo)準(zhǔn);砌塊傳熱系數(shù)為0.447W/(m2·K),遠(yuǎn)遠(yuǎn)低于同樣規(guī)格的實(shí)心磚;砌體傳熱系數(shù)為0.35W/(m2·K),比純頁(yè)巖實(shí)心磚墻體的傳熱系數(shù)降低66.35%,比加6%鋸末頁(yè)巖實(shí)心磚墻體的傳熱系數(shù)降低27.08%,符合嚴(yán)寒及寒冷地區(qū)的建筑節(jié)能要求。最后,成功將29排孔加鋸末燒結(jié)頁(yè)巖保溫空心砌塊應(yīng)用于嚴(yán)寒地區(qū)示范建筑上,實(shí)現(xiàn)單一材料滿足建筑節(jié)能的要求。
[Abstract]:With the rapid development of China's economy, the energy problem is becoming increasingly prominent. Energy conservation has become the key link to achieve sustainable development. Since 2008, the construction industry in China has ushered in a peak of development. Too many high energy consumption buildings will make the building energy consumption exceed traffic, industry and other industries and eventually occupy the top of the social energy consumption, reaching about 30%. The thermal performance of the enclosure structure is the main reason for the high energy consumption of the building, therefore, the main reason for the high energy consumption of the building is the poor thermal performance of the enclosure structure. Improving the thermal performance of the envelope structure is the main way to solve the high energy consumption of the building. As a new type of wall material, the sintered hollow block has excellent properties such as fire resistance, same life with the building, good insulation performance, etc. It is an ideal new type of wall insulation material. This paper mainly studies the properties of sintered insulating hollow block in laboratory, and explores the effect of the addition of pore-making agent on the thermal properties of the material. The conclusion obtained from the laboratory is that 29 rows of hole additive sintering hollow block is produced in the field in the factory. According to the mechanical and thermal properties of the actual product, the feasibility of its application in building energy saving is analyzed. Finally, the product is successfully applied to the demonstration building to meet the building energy saving standards. Firstly, the physical and chemical properties of raw materials and pore-making agents are analyzed. The results show that the chemical and mineral composition of Xinjiang shale is suitable for the preparation of sintered hollow block, the firing temperature range of shale is 850 ~ 1050 鈩，
