Berson Rizhao City, Shandong Province Building Materials Technology Co., Ltd. (www.cnbsfs.com) is located in Rizhao City, Shandong Rizhao Rizhao City, a new urban Jinan City Garden Road 17-A, Contact: Lin Dong Process Step: The leveling layer Emery when leveling the ground is dry warehouse processing, will be spread evenly on aggregate screed; Step two: reinforced corners, polished floor; Third step: in place sawing concrete warehouse floor joints do processing, and fill it up with fillers; Step 4: roller coating with transparent sealant Shandong warehouse ground handling, smooth power trowel, trowel, received light, maintenance indicators technical indicators to detect non-metallic items compressive strength ( MPa) ≥ 58.1 ≥ 58.1 flexural strength (MPa) ≥ 12 ≥ 12 rebound hardness value impact 0.19j0.19j 4545 general concrete floor with non-slip concrete floor with the general ground firing ground fire resistance and oil resistance angry intensity unchanged for three years , oil seepage 0.03mm rust resistance 5 ℅ Nacl solution soak for 2 years and 3 months of rust many factories laying on the ground floor of the emergence of aging, cracking and other phenomena, it is because destroying the external environment, it is itself a qualitative change occurs ? Actually, the reason these two areas have warehouses ground processing factory, and even the human factor. Sunshine Emery floor damaged some of the external environmental factors factory floor is laid in the open space environment, which makes it vulnerable to the effects of wind and sun, thus exacerbating the ground aging.
