新型建材──泡沫铝近年来美国、日本、欧洲正在加紧研制一种新型建筑材料－－泡沫铝。目前，泡沫铝的制造，大多采用直接发泡法，即在熔融的铝液中加入发泡剂和增粘剂，以强力搅拌使之混合均匀，恒温使发泡剂分解，放出气体，经冷却后便可得到气泡尺寸均匀、质地优良的泡... New Building Materials - Foamed Aluminum In recent years, the United States, Japan, and Europe are stepping up the development of a new type of building material - aluminum foam. At present, most foam aluminum production uses direct foaming, ie adding foaming agent and tackifier to the molten aluminum liquid, mixing it with strong stirring to make it evenly mixed, decomposing the foaming agent at constant temperature, releasing gas, cooling Afterwards, bubbles with uniform bubble size and fine texture can be obtained...
