2000年,大学毕业的任宗汉经常出差,他发现在发电厂门口常堆放着大量粉煤灰等废弃物。从小就喜爱发明的他经过了上千次的反复实验,终于在2004年研制成功了能把废弃物变废为宝的新型无机材料强力发泡专利技术。该技术是利用石粉、矿渣、尾矿砂、粉煤灰、河沙、建筑垃圾等任一种废料为主料,加入部分胶凝材料和助剂等混合搅拌后简单快速化学发泡,在常温下向自制模具内浇注后自然固
In 2000, Ren Zonghan, a graduate of the university, often traveled on business. He found that a large amount of waste such as fly ash was often piled up at the gate of the power plant. He loved to invent an early age after thousands of repeated experiments and finally developed in 2004 to transform the waste into a treasure of new inorganic materials powerful foam patented technology. The technology is the use of stone powder, slag, tailings sand, fly ash, river sand, construction waste and other waste materials as the main material, adding some cementitious materials and additives, such as mixing simple rapid chemical foaming at room temperature After pouring into the homemade mold natural solid
