Do you think that the flatter the ceiling looks, the better it will be? In fact, if the decoration only look at the surface, decoration knowledge is also hearsay, then you are very easy to enter the error zone, and today Xiao Bian will take you to find out, what are the common errors in the acceptance of the ceiling! Misunderstanding 1. The flatter the ceiling is, the finer the construction, the better. Many people believe that the smoother the ceiling, the better the standard for the construction of the ceiling. This is not the case. In fact, the flatness requirement of the ceiling ceiling is different from the flatness requirement of the floor surface. Although the ceiling should be stable and firm, generally speaking, considering that the keel is sagging in the future, the center of the keel should be erected from the short side by 1/200 as a standard. Misunderstanding 2, good reflective ceiling represents its quality Some homeowners believe that a good reflective ceiling represents good quality. When it comes to acceptance, the requirements for the lightness of metal ceilings are often greatly increased. This idea is a misunderstanding of ceiling acceptance. In fact, the ceiling buckle plate only needs to be firmly installed, and no flaw on the surface is enough. There is no need for too much glossiness, and a ceiling that is too smooth and highly luscious is not good for indoor space. Third, only pay attention to the ceiling surface, stability, quality, etc., ignoring the cleanliness of building materials In fact, there are a lot of stains in the construction may not be cleared, so when the acceptance of the ceiling should also pay attention to whether the clean end of the ceiling decoration work is in place, do not because the decoration workers say "after finishing a decoration step, how to reunification "There is no problem with scrubbing." Tips: More practical decoration knowledge, real scene with the shoot, please pay attention to the palm of this site (micro signal: mall_jia). Ceiling new house acceptance considerations
Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.
