The tatami platform is mainly composed of fork plates (also called solid wood plates) and blockboards (also called big core plates). There are also technical masters who use cement blocks. Here are some of the materials that can be used to make a tatami floor: fir, high-grade wood board, solid wood, pine, pine and oak. 
Although fir pine is also a solid wood, the price is very cheap, but it is not recommended under geothermal conditions. Because the pine material is loose, the strength is small, the smell is great, and the nail holding power is poor. 
Oak oak is not an ideal material for tatami platforms. Because of the thermal expansion and contraction of the two types of plates, the cover of the ground platform will not expand well in the summer, and there will be gaps and cracks in winter. Basically after a year or two, There will be problems. And these solid wood floors often have to be made on site and then painted with a varnish. After the lids are covered with lids, it is difficult to completely disperse the taste and it is not environmentally friendly. 
Pinus sylvestris Pinus sylvestris has a high price and soft texture. It is very resistant to scratches. Friends with limited decoration budget must choose carefully. 
Xiao Bian suggested that Xiao Bian suggested using solid wood particle board or ecological board, not only from environmental considerations, but also because of the following reasons: 
1, solid wood particle board holding nail force is very good, you can repeatedly hit nails, you can nail round nails, screws. These machinability performances are significantly better than those of the density board; the density of the wood particle board is higher, the wood fiber particles in the board are larger, and the nature of the natural wood is retained more; the warp and deformation of the wood particle board is small, the dimensional stability is good, and the strength is high Stiffness is good, not easy to bend. 2, the ecological board This kind of plate can be recycled, but also non-flammable, does not contain formaldehyde, toluene and other harmful substances, waterproof, anti-corrosion, pest control, anti-mildew features readily available. In addition, the color of the plate can be arbitrarily matched, and the installation is very simple, and it can be directly used without painting, and the plate color is also long-lasting without fading.

PPE insect screens are usually made of high-quality materials such as polyester, fiberglass, and aluminum. These materials are strong, durable, tear and abrasion resistant, making them ideal for continuous use in different environments. The screen is also coated with a special layer to increase its resistance to UV radiation, heat and chemicals, thus prolonging its lifespan. Additionally, PPE insect screens are designed to provide excellent visibility and airflow while protecting workers from insect bites, dust and debris. This makes them indispensable personal protective equipment for industrial workers who may be exposed to insects and other airborne particulate hazards.
