Surface cleaning is the basic work of daily maintenance of lcb fire-proof core panel in door. In daily use, the surface of the door body is very easy to absorb dust and stains, and even suffer from water stains and oil stains, which will not only affect the appearance of the door body, but also damage the surface coating, thereby affecting its protective performance. Therefore, it is necessary to wipe the surface of the door body with a soft damp cloth. During the wiping process, pay attention to the uniform force to avoid scratching the surface coating due to improper force. For stubborn stains, you can choose a special mild detergent, spray the detergent evenly on the stains, wait for a while, and then wipe it gently with a damp cloth. It should be noted that the detergent cannot contain corrosive ingredients, and during the cleaning process, the detergent should be avoided from penetrating into the gaps of the door body and directly contacting with hardware accessories to prevent corrosion. After cleaning, use a clean dry cloth to wipe off the residual moisture to avoid moisture residue causing the door body to become damp and deformed. Normally, it is recommended to clean the surface at least once a week. If the door is in an environment with a lot of dust and frequent personnel flow, such as commercial places, hospital corridors, etc., the cleaning frequency should be increased to once every 2-3 days according to the actual dirtiness, to ensure that the door surface is always clean and tidy, and to effectively protect the surface coating.
As a key component to ensure the normal use of the lcb fire-proof core panel in door, the performance of hardware accessories directly affects the smoothness and safety of the door opening and closing. The hinge is the core component of the door body for load-bearing and rotation. During daily maintenance, it is necessary to carefully check whether the hinge is loose, deformed or worn. The inspection method is to gently shake the door leaf by hand. If you feel obvious looseness or hear abnormal noises, you need to tighten the hinge screws with a screwdriver immediately, and check whether the hinge shaft needs to be lubricated. As an important device to ensure safety, the door lock should be regularly checked for the flexibility of the lock core. You can test it by inserting the key and gently turning it. If there is a jam during the rotation, you should use a professional lock core lubricant to lubricate it in time to avoid malfunction of the door lock due to rust or dust accumulation in the lock core. The door handle should not be ignored either. Check whether it is firmly connected to the door body. If it is found to be loose, tighten the fixing screws in time. In addition, auxiliary hardware accessories such as door stops and door closers also need to be checked regularly to ensure their normal functions. For the inspection and maintenance of hardware accessories, it is recommended to conduct a comprehensive inspection once a month. For places with large traffic and frequent use, such as shopping malls and office buildings, the inspection cycle should be shortened to once every two weeks to promptly discover and solve potential problems of hardware accessories and ensure the normal use of the door body.
The door body gap and sealing strip are the key factors that determine the fireproof and sound insulation performance of the lcb fire-proof core panel in door. In daily maintenance, it is necessary to focus on checking whether the gap between the door frame and the door leaf, and between the door leaf and the ground is uniform. Under normal circumstances, the gap width should meet the requirements of relevant standards and is generally controlled between 2-4 mm. If the gap is found to be too large, it may cause smoke and flames to leak when a fire occurs, reduce the fireproof performance of the door, and also affect the sound insulation effect. At this time, it is necessary to check whether the door body installation is displaced and whether the door frame is deformed. If necessary, contact professionals for adjustment. The state of the sealing strip is equally important. Check whether the strip is aging, cracking or falling off. Aging strips will lose elasticity and cannot fit tightly to the door body, thus weakening the sealing performance. Once a problem is found with the strip, a new strip should be replaced in time to ensure that the door body can form a good sealing effect when it is closed. It is recommended to check the gaps and sealing strips of the door body once a quarter. When the seasons change, the door body may be slightly deformed due to thermal expansion and contraction due to large changes in temperature and humidity. At this time, it is necessary to strengthen the inspection. If necessary, adjust and replace the strips in time to ensure the sealing and fireproof performance of the door body.
The core function of the lcb fire-proof core panel in door is fire prevention, so the maintenance of its fireproof performance is crucial. Although actual fireproof tests cannot be performed in daily use, they can be evaluated through a series of indirect methods. First, regularly check whether the surface of the door body is damaged, dented or deformed, especially the edges and corners of the door, which are easily damaged by collision during use. Once damaged, the fireproof core board may be exposed, affecting the overall fireproof performance. Secondly, check whether the fireproof mark on the door is clear and complete. The fireproof mark is an important basis for judging whether the door meets the fireproof standards. If the mark is blurred or missing, it is necessary to contact the manufacturer or relevant departments in time for confirmation and processing. In addition, you can also check whether the door is tightly closed and whether there is a large gap that causes obvious air circulation, which may also affect the fireproof effect. For the inspection of fireproof performance, it is recommended to conduct a comprehensive assessment every six months. If the building has special fireproof requirements or is in a high-incidence area of fire, the number of inspections should be appropriately increased according to the actual situation to ensure that the fireproof performance of the door is always in good condition.
In order to ensure that the lcb fire-proof core panel in door opens and closes smoothly in daily use and reduce component wear, it is necessary to lubricate the door opening and closing components regularly. In addition to lubricating the door lock, the door hinges, door closers, pulleys (if any) and other components also need to be paid attention to. When lubricating the hinges, you should use professional lubricating oil, drip the lubricating oil on the hinge shaft and the connection parts, and then gently turn the door leaf to evenly distribute the lubricating oil. This can effectively reduce the friction between the hinges, reduce the degree of wear, and extend the service life of the hinges. For the door closer, according to the requirements of the product manual, add appropriate hydraulic oil regularly to ensure that the door closer can work normally, realize the automatic closing of the door and the closing force is moderate. If the door is a sliding door, its pulley and track also need to be lubricated. You can use lubricant to spray on the surface of the pulley and track, and then push and pull the door leaf repeatedly to make the lubricant fully play its role, reduce the friction between the pulley and the track, and avoid damage to the pulley or poor door pushing and pulling due to excessive friction. Generally speaking, the lubrication treatment of the door opening and closing parts can be carried out once every six months. If the door is used very frequently, such as the entrance and exit doors of large shopping malls, the lubrication cycle can be shortened to once a quarter to ensure that the door opening and closing parts are always in good working condition.
The surrounding environment of the door body has an important impact on the service life and performance of the lcb fire-proof core panel in door, so comprehensive maintenance and management are required. First of all, it is necessary to ensure that the passage around the door is unobstructed. It is strictly forbidden to pile up debris near the door, such as cartons, tools, and building materials. These debris will not only hinder the passage of people, but also may affect the normal opening and closing of the door in an emergency such as a fire, delaying the escape and rescue time. At the same time, the accumulation of debris may also cause collision and extrusion of the door body, causing deformation and damage to the door body. Secondly, pay attention to the condition of the wall around the door and check whether there are cracks, water seepage and other problems in the wall. Cracks in the wall may cause rainwater to penetrate, causing the door body to be damp and deformed, affecting the performance of the fireproof core board; water seepage in the wall may also cause the door body hardware accessories to rust and reduce its service life. If problems are found in the wall, contact professionals in time to repair them to prevent the problem from further deteriorating. In addition, fire-fighting facilities near the door, such as fire extinguishers and fire hydrants, should also be kept intact and easy to use, and should not be blocked or damaged. For the maintenance of the environment around the door body, it is necessary to pay attention to it at any time during daily use, and deal with problems in a timely manner. At the same time, the overall environmental inspection and maintenance of the building can be fully evaluated and rectified once a year to ensure that the environment around the door body is always in good condition.
Although daily self-maintenance can solve most problems, LCB fire-proof core panel in door still needs comprehensive and in-depth maintenance and inspection by professionals after a certain number of years of use. Professional maintenance personnel have rich experience and professional testing equipment, and can conduct more detailed inspection and evaluation of the door body. They can use professional instruments to test the fire resistance of the door body, such as testing the fire resistance limit and smoke penetration of the door body, to determine whether the door body still meets the fire protection standard requirements. At the same time, professionals can also conduct a comprehensive inspection of the structure of the door body, including whether the connection between the door frame and the wall is firm, and whether the fireproof core panel inside the door body is displaced or damaged. For hardware accessories, professionals can perform more precise repairs and adjustments to ensure that their performance is in the best condition. In addition, professional maintenance personnel can also provide targeted maintenance suggestions and maintenance plans based on the actual use of the door body. Generally speaking, it is recommended to invite a professional door maintenance team or manufacturer's after-sales personnel to conduct a comprehensive maintenance and in-depth inspection of the LCB fire-proof core panel in door every year. For doors that have been in use for a long time, are used frequently or are in special environments, the number of professional maintenance should be appropriately increased to promptly discover and solve potential problems, extend the service life of the door body, and ensure its fire resistance and safety of use.
