The bricks and tiles that were transformed in the village of the city and the old city were transformed into energy-saving technology and transformed into new environmentally-friendly building materials. A few days ago, the reporter learned from Henan Xulong Recycling Resources Co., Ltd. that the company has made comprehensive use of various types of construction waste to make new building materials. After more than two years of innovation and development, it has explored the experience of recycling construction waste.
Henan Xulong Recycling Resources Co., Ltd. and Taiwan Emperors Co., Ltd. carry out technical cooperation and quote world advanced technology. Into the production workshop of Xulong Company, four storage tanks have been placed in the middle of the aggregate sorting workshop and the brick making workshop. The forklift continues to send construction waste to the crusher in the sorting workshop, and a large amount of construction waste is crushed. After dustless treatment, it is conveyed through the conveyor belt to the screening machine for screening and separation of impurities. The criss-crossing conveyors kept running. Under the control of fully automated microcomputers, the ends of the conveyors flowed out of four kinds of building aggregates: coarse, medium, fine, and powdery. The continuously flowing aggregates piled up in a cone shape. A small amount of cement is mixed with these aggregates through mixing, and then mixed into a raw material warehouse for making bricks. The fully automated computer digitally controlled pallet conveyor and mold press machine work in coordination and cooperation. The blanks of the molded products are transported from the molding machine; they are sent to the solar conservation kiln by the process vehicle. After a few hours of maintenance, the colorful floor tiles, bricks, and permeable bricks are neatly placed in the delivery of the forklift. Surrounded by shaded freight yards.
"Each piece of solid brick produced can consume more than 4 pounds of construction waste." Zhu Yulong, chairman of the company, told reporters that the ground hardening products produced after the recycling of construction solid waste mainly include square bricks and Dutch bricks. Permeable bricks, etc.; wall materials are mainly self-insulating brick composite materials, the entire process does not need to be fired, does not produce sewage, smoke, can effectively prevent air pollution and other issues. It is understood that the standard bricks, floor tiles, and perforated bricks produced by the company are inspected by the quality inspection department and are in compliance with the standards. No radioactive contamination, bulk density and water absorption rate are better than ordinary concrete porous bricks, between the sintered bricks and the non-fired bricks. The structural properties of raw materials of production methods have not changed, and their shrinkage and thermal conductivity are smaller than those of ordinary concrete products, which is very beneficial to construction.
Xulong Company expects to clear 3 million tons of construction waste every year. It can produce 280 million blocks of pervious concrete blocks, 500,000 cubic meters of wall materials, 500,000 cubic meters of recycled aggregate, roadbed materials, and 200,000 cubic meters of backfill. Soil, recultivated soil, 300,000 cubic meters of machine-made sand, 500,000 tons of special micro-powder and other new building materials, the annual disposal of construction waste can save nearly 300 acres of land.
