Floor maintenance away from bacterial infestation
Investigators have conducted surveys in Beijing and Shanghai. Among the samples of solid wood flooring with three years of 60 years, 12 years, and 3 years, the smallest gap was 0.9 mm, the largest was more than 6 mm, and the average floor space per square centimeter was. There are 4.56 grams of gap waste, and the average number of bacteria is 7 times the minimum standard of the hospital. The main pollutants in the crevices of the indoor floor are mold, dust mites, bioactive substances and inhalable dust. In order to prevent bacteria in the floor from infiltrating our body, we must pay attention to the maintenance of the floor during the use of the wooden floor. To avoid sun exposure near the balcony or windows, it is best to apply thick curtains when the sun is strong. Second, avoid moisture. Do not wipe directly with a wet mop. When water or other liquid food is spilled on the floor, dry it in time. , To prevent excessive moisture penetration into the wood floor, resulting in moldy, rotten, should use a special cleaning agent for wood floors to prevent cracking the floor. Cleanliness is an important step in protecting the health of the living room. In the case of cracks in the floor, it should be cleaned to prevent accumulation of dirt. When cleaning the floor, focus on using a vacuum cleaner to extract dust and debris from the cracked area. If accumulated dirt cannot be sucked out, or where corners and other places are difficult to clean, brush with a small brush, scrub the floor cleaner, or directly on the floor. Clean the disinfectant and pour it on the rag. The traditional installation method of wood floors adopts the keel method. There is an overhead layer between the floor and the floor. The moisture in the keel can infiltrate beverages, milk, and other liquids in a vacuum, and it is easy to breed bacteria and insect pests. The new viscose installation method and metal keel installation method can avoid the disadvantages of the wood keel installation method. The viscose method uses the environmentally friendly floor glue to directly adhere the floor to the cement floor, which can eliminate the potential for dust accumulation under the floor. space. However, it is forbidden to use cement to fix the keel so as to avoid moisture deformation of the floor. Nature floor del floor window cement interior decoration home space
A double-convex lens is compose of two convex surfaces, has a positive focal length. Normally Bi-Convex lenses are most suitable where the object and image are on opposite sides of the lens, and are popular for many imaging applications.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
We supply kinds of plano-convex
