Purchase knowledge of entering the door
1. Check the process quality:
Special attention should be paid to check whether there are welding defects, such as open welding, unwelding, missing welding, etc. Check whether the fit between the door leaf and the door frame is dense, whether the gap is uniform, whether the opening is flexible, whether all joints are dense, the surface of the door panel should be anti-corrosion treatment, generally painted and plasticized, the surface of the paint layer should be bubble-free and the color is uniform. Most doors also have rubber sealing strips embedded in the door frame, so there will be no harsh metal collision sound when closing the door.
2. Door body thickness:
The thickness of the steel plate of the qualified entrance door frame should be above 2mm, and the door body thickness is generally above 20mm. The weight of the door body should be checked, generally above 40kg, and the internal structure of the door body can be checked by removing cat eyes, doorbell box or lock handle. The thickness of the door body should be above 1.0mm, and there are several reinforced steel bars inside, so that the front and rear panels of the door body are organically connected together to enhance the overall strength of the door body. It is best to have asbestos and other materials with fireproof, thermal insulation and sound insulation functions as fillers in the door. Knocking the door body with your hands makes a "dongdong ”" sound. Consumers should open and close the door with their hands.
3. Lock inspection:
Qualified entry doors generally use special anti-theft locks that have been tested by the public security department. At the same time, steel plates with a thickness of more than 3.0mm should be protected at the locks. Many of the anti-theft special locks are multi-directional locks. The advantages are that not only the door locks can be locked, but the upper and lower cross bars can be inserted into locks to fix the door. The door's anti-plitting performance is greatly increased. The "GA/T73—94 Mechanical Anti-theft Lock" issued by the Ministry of Public Security clearly stipulates that mechanical thief anti-theft door locks are divided into ordinary protection levels and advanced levels, expressed as A and B levels. A Class A lock refers to a lock with an anti-destructive opening time of no less than 15 minutes and an anti-technical opening time of no less than 1 minute. A Class B lock refers to a lock that prevents damage opening time of no less than 30 minutes and an anti-technical opening time of no less than 5 minutes (Anti-technical opening refers to the lock resistance to the ability of professional and technical personnel to use special tools to open the lock using operating methods). And in the same situation, the safety performance of Class B anti-theft lock is 5 times that of Class A lock. Finally, you have to weigh the weight of the entrance door. The weight of the regular entrance door is generally more than 70 kg.
Cleaning of entry doors
Daily cleaning of door panels can be wiped with soft and dry cotton cloth. If there is serious stain on the door panel of the inner door, you can use neutral cleaning agents or furniture-specific cleaning agents to clean the stain first and then dry wipe it; if the door panel is made of resin or metal sheets to remove slight scratches on its surface, you can use a soft cloth to dip in a small amount of toothpaste for repeated wipes; if the door panel is made of wood or painted boards, regular waxing is an effective way to keep the surface bright and bright; glass or resin sheets do not need to be waxing. Replastic steel plate products should protect the replastic film to avoid scratches; plastic sprayed steel plate products should avoid being stained with water or other difficult-to-remove scaling or corrosive substances to extend the service life of the anti-theft door. It is recommended to cover the protective film on the plastic board after decoration, or cover the plastic spray board with a layer of film.
Maintenance of entry doors
Nowadays, many families have installed security doors, some have a long installation time, while others have a short installation time. It takes a long time to install it. If you don’t pay attention to the correct usage method, and if you don’t take care of it normally, you will be more or less dissatisfied with it now. The correct way to use it is: when entering and exiting the door, do not use too much force to close the door, and do not use violence to hit the door. Use the key to open and close the door. The security door you are using must be maintained once a year.
If the anti-theft door has been used for more than one year, the various pins and contact points of the anti-theft door may rust. You can use good lubricating oil and apply each pin and contact point to increase the lubrication effect. Remember not to apply oil to the holes.
