Plastic Injection Molded Connector Accessories
Mechanical properties of injection connector fittings as far as connection functions are concerned, insertion and extraction forces are important mechanical properties. Plug force is divided into insert force and pull out force (pull out force is also called separation force), the requirement of both is different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which indicate that, from the point of view of use, the insertion force should be small (hence the structure of LIF with low insertion force and ZIF without insertion force), and if the separation force is too small, it will affect the reliability of contact.

The water in the floor heating pipe is accumulated for a long time, and a large amount of microorganisms in the water will produce a large amount of biological slime under suitable conditions. The slime adheres to the inner wall of the floor heating pipe. Over time, it will affect the heating temperature of the floor heating system, which will lead to a drop in the indoor temperature. According to relevant data, during the operation of the water-heating system, the thickness of the inner wall of the floor heating pipe is increased by 1 mm to reduce the indoor temperature by 6 degrees Celsius. This not only affects the normal heating effect, but also causes a great waste of energy. In addition, under the high temperature conditions for a long time, a large number of bacteria will grow on the inner wall of the floor heating pipe, which will cause harm to the user's physical health and living environment.
Floor heating worthy of attention
In addition, excessive accumulation of biological slime in the floor heating pipe may also cause partial blockage in the floor heating pipe. If it continues to be used, it may cause blockage in the floor heating pipe. Once this happens, it can only damage the ground, remove or replace the floor heating system to solve this problem. This will not only bring inconvenience to the user's life, but also cause serious economic losses to the user.
Therefore, the dirt in the floor heating pipe must be removed in time. Since the filter at the front end of the water collector can only prevent large particles of pollutants from entering the piping system, it will not be able to filter scale, sludge, and bacteria and algae. Therefore, the fundamental method to solve the fouling problem of the floor heating pipe is to clean the floor heating pipe periodically. Under normal circumstances, the water floor heating system should be regularly cleaned and maintained for more than two years.
The floor heating time can be before heating, during heating, or after heating. Cleaning before heating can completely remove the biological slime impurities in the tube, so as to ensure the normal use of the floor heating during heating, so that the indoor reaches the optimal temperature. When cleaning in heating, you can intuitively feel the change in temperature rise. Cleaning after heating is the most important. Because of the poor water quality during heating, individual heating companies will add dyes and other substances to the heating water to prevent users from stealing water. This substance will cause water quality to decline and promote the deposition of impurities. At this time, if the above substances are not completely removed, a large number of bacteria will seriously harm the user's physical health. Therefore, regular cleaning and maintenance of the water heating system is very important.
Because few people will remind users to warm the water floor heating system in time, and the current floor heating industry has not yet formed a scale, most users' water heating systems are in a state of letting go. At present, there are three main methods for the cleaning of floor heating pipes: chemical soaking, projectile cleaning, and pulse wave physical cleaning.
Chemicals soaked and cleaned. This cleaning method can fully dissolve the slime adhered to the pipe wall. The high-quality food grade raw material used by it does not cause corrosion to the floor heating pipe and is thoroughly cleaned. The disadvantage of this cleaning method is that some market speculators often use low-cost strong acid formulations, which can cause corrosion of piping and related components.
Shooting bomb cleaning. This cleaning method utilizes the friction between the cleaning bomb and the pipe wall to remove the slime adhered to the pipe wall and does not damage the warm pipe, so the cleaning is thorough. The disadvantage of this cleaning method is that the floor heating pipe needs to be removed. If the underground pipeline has a joint, the construction is very inconvenient and it is easy to get the cleaning bomb stuck in the pipeline. In addition, it may also cause secondary damage to the relevant parts of the original manifold, valves, etc.
Pulse wave physical cleaning. This cleaning method does not require chemicals, does not remove the warm pipe, cleaning more thoroughly. Its unique cleaning principle can simultaneously clean the manifold and valve of the floor heating manifold, avoiding long-term fouling and valve blockage. The disadvantage of this cleaning method is that it is limited by space during construction, and in particular, some users' floor heating manifolds are installed in shelters, and the distance between the two ends of the manifold is too close to the wall, which makes construction more difficult.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, which is called mechanical operation in GB5095. It is based on a cycle of one insert and one pull, and whether the connector can normally complete its connection function (such as contact resistance) after the specified plug cycle. The plug force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the contactor structure (positive pressure size) and the dimensional accuracy (alignment) of the contactor.
The three most effective methods of inventory cleaning
As floor heating knowledge becomes more and more popular, more and more floor heating homes pay great attention to the cleaning of floor heating coils. Floor heating cleaning can prevent the decrease of heating effect and the service life of remote floor heating, but the floor heating methods are also very numerous. That method is the best and most effective method. The professionals who have warmed up the new scenery will count the three most effective ways to clean the floor.
