1. Be sure to check the end of the wooden keel
The unevenness of the ground caused some solid wood floors and wooden keel to be suspended and stepped on it. The solid wood floor was easy to make noises. If the wood keel is not firm, it is easy to produce the same situation, so be sure to check the wood keel after it is finished. You can step on the wooden keel with your feet and check if the wooden keel is firm by shaking your feet.
2 solid wood floor measurement work can not forget
After laying the first row of solid wood flooring, the installer should pull the straight line to measure the level. If it needs to be adjusted immediately, it will affect the laying of the solid wood floor. After laying, it is better to take the ruler upright on the solid wood floor. Look for gaps.
3. Wood keel to do drying and tamping
The moisture content of a generally qualified solid wood floor is 12%. After the wood keel is dried, the wood flooring will not absorb moisture quickly due to a large humidity difference, causing the solid wood floor to arch and the paint surface to burst. The solid wood flooring has good log properties and is prone to worms. Therefore, it is necessary to put swarf into the wooden keel. The standard is to put one kilogram of smashed wood chips per 8 square feet, and be careful to put it evenly.
4. The color difference problem pays attention in advance
The color of each solid wood floor will be different. Therefore, before the formal laying, solid wood floors with similar colors and textures should be selected so that there will not be large differences in the overall pavement effect. It should be noted that when the solid wood floor comes into play, it is best to check the quality of the solid wood floor through hand touch and visual inspection, and to find and exchange any problems in time.
Moisture-proof mat laying pay attention to avoid water vapor 'infection' on the wall to the solid wood floor, in the laying of moisture-proof pad, not only to cover the entire wooden keel, but also pay attention to the moisture-proof pad along the corner to stay up 10CM or so. At the same time, expansion joints should be left between the solid wood floor and the wall. If it is put too close, the solid wood floor will bulge easily after expansion.

Flexible rubber soft joint is also called Rubber Joint, rubber flexible joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a kind of high elasticity, high air tightness, medium resistance and weather resistance. The pipe joint is a hollow rubber product that acts as a flexible connection between metal pipes
The rubber soft joint products take advantage of the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.
Flange for connecting rubber joint: DIN BS ANSI JIS standard
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Material of main parts
Ball body: natural rubber, neoprene, butyl rubber, nitrile rubber, fluorine rubber, EPDM
Inner and outer lining: natural rubber, neoprene, butyl rubber, nitrile rubber, fluororubber, EPDM, PTFE
Main Frame: Nylon Cord Flange: Cast, Forged Carbon Steel (Q235), Stainless Steel (201, 304, 316, 321), Plastic (PVC, PPC)
The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃~120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃~250℃.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
