For flooring, the general view of everyone is that solid wood flooring is more environmentally friendly than laminate flooring. However, if the floor covering is not environmentally friendly, even if a solid wood floor with excellent environmental performance is selected, the result will be indoor pollution. So, what kind of floor covering process is considered environmentally friendly?
With the improvement of people's environmental awareness, people are increasingly aware of how important a healthy living environment is. Therefore, in the process of home decoration, environmental protection has naturally become a topic requiring special attention. From the environmental protection indicators of the decoration materials to the environmental protection grades of furniture furniture have become people's "preparatory compulsory courses." In fact, the purchase of environmental protection items is just a beginning. What we need to do afterwards is to introduce environmental protection technology into the decoration process.

Professional floor covering technicians stated that the currently popular floating floor paving method is regarded as a more environmentally friendly floor paving method because of its no glue paving, convenient repair and disassembly.
According to the supervision of the floor pavement, the biggest advantage of the floating paving method is that it does not use glue to fix the floor on the floor, and the floor can also be used without glue, so you don't have to worry about the formaldehyde contained in the glue. Indoor pollution is caused; secondly, the laying process is simple and fast. Since the floors are all spliced ​​on the ground, the local panels can be easily repaired and replaced when they are accidentally damaged from the joints or parts; after the moving or accidentally running floor is immersed, the dried floor can be removed and the second floor can still be paved. The equipment is very cost-effective. At present, this glue-free suspension floor pavement method is a more scientific, economical and environmentally friendly pavement method, but it is only to remind consumers that if they are going to use this kind of pavement method, they should try their best to choose flooring. Select those floors where the tongue and groove are tight and the bottom seam is small.
Before laying the floor, the ground surface, that is, the base level, is first processed, usually to check the flatness and moisture content of the base layer. The flatness of grassroots is higher, and it should be less than 2-3mm, and the moisture content should not exceed 20% in general. If geothermal heating is used, the moisture content should not exceed 10%. Otherwise, the floor cannot reach the standard after laying. In addition, the paving technician of the living floor said that if the floor is laid on the ground floor of the building or the bungalow, the waterproof layer must be treated on the ground floor.
After checking the standards at the basic level, it is necessary to carry out the laying of cushions (the solid wood floor can also be sprinkled with some insect powder on the ground to protect the floor). There are many kinds of cushion materials, you can use a kind of foam pad called the moistureproof pad, the approximate thickness is about 3mm, with plastic film, butt laying, plastic interface. You can also choose to make a mat, generally choose 10-12mm thick, butt laying, plastic interface. In addition, you can choose high-quality multi-layer plywood mat. The main purpose of the mat is to play a role in moisture protection, of course, it can also help increase the sense of foot.
After everything is ready, the floor can be paved. If it is a solid wood floor, then before the formal paving, the floor used in a space should be roughly laid out for color separation, and the colors of the floor should be assembled together as much as possible. . In addition, wood wedges should be placed between the floor and the wall to allow for expansion joints. During winter paving, the interior should be relatively dry and the expansion joints should be kept small. In summer, the air is more humid and the expansion joints must be larger.

The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings are available as full complement (no cage) or with cages made from PTFE, PEEK or 316 stainless steel.
These are non magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial clearance for full ceramic bearings is C0 but other clearances can be supplied to order.
ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.
The Description of Ceramic Bearings:
Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.
Firstly, they can be used in corrosive environments. Compared to stainless steel bearings, hybrid and all Ceramic Bearing lasted three and twenty times longer respectively. It is presumed that water readily adheres to silicon nitride and forms a better lubrication film, leading to extended bearing life.
Secondly, they can be performed in corrosive agents. Generally, silicon nitride has excellent corrosion resistance. However, corrosion resistance varies depending on the type and quantity of sintering additives, and certain corrosive agents decrease in hardness and flexural strength. In such situation, it is can be proved that the carbide-based ceramic bearings are the most effective.
Thirdly, they can be used in high-temperature vacuum. An all-silicon nitride Ball Bearing with a self-lubricating laminated cage (mainly composed of MoS2) and with MoS2-coated rings and balls proved superior in durability in a high-temperature vacuum environment. Compared with the hybrid bearings, the all-ceramic bearing was superior in both dynamic frictional torque and life.
Fourthly, they can be performed with poor lubrication. As ceramics are extremely hard and have outstanding wear resistance, they outperform other materials in bearing life without lubrication. According to a test, the steel bearing seized within a short period while the hybrid and all 627 Ceramic Bearings, though sustaining wear, did not. And the all-ceramic bearing sustained considerably less wear than the hybrid bearing, indicating that its endurance life is much longer.
