Second, the paint of the security door has fallen off. How to fix it?
Repair the paint that falls off the security door, wasting materials and manpower!
You just need a little paint! The specific construction points are supplemented as follows:
1. polyester paint must be used for painting.
2. The color should be the same as that of the original security door after mixing, painting and drying. Otherwise, readjust the colors until they are consistent.
3. Dry after repeated brushing, and smooth with sandpaper. Until the paint film is flat.
Third, the security door paint repair steps
The details are as follows: 1. Check whether it is a refurbished old door. One trap to avoid when buying security doors is that some small shops selling security doors on the street will recycle some old security doors and then renovate them and sell them again. To check whether it is a refurbished old door, you can pay attention to the turnkey process. Under normal circumstances, the packaging of new security doors is intact. The installer should pack it in front of the customer, and the key should be in the package. The packaging of the key should also be complete. The lock core should be installed in front of the customer, and then give the key to the customer. But if the packaging of the door itself is damaged and the key is in the pocket of the worker, it is possible to renovate the door. Second, it is incredible to check whether the security door made of paper is made of paper. Some security doors use steel plates on the surface, but the fillers in the interlayer are filled with paper. According to a dealer, the country originally stipulated that paper can be used as filler, but this paper must be honeycomb paper. But now there are some manufacturers in the market who do use ordinary paper shells as fillers. Although honeycomb paper can be used, it is generally used for low-grade doors because it does not sound insulation and heat preservation. The standard filler is foaming agent, which can keep warm and sound. The disadvantage is that the fire protection performance is poor, but it can realize theft prevention. Even better is the cotton residue.
Test method: check what filler is used. You can have a look at the security door when you install it. Usually you can see what's inside by unscrewing the cat's eye from the door. If some cat's eyes are already installed and can't be unscrewed, you can look at them when you lock the door. In addition, it is best for the manufacturer to indicate what kind of filler is used when signing the contract, so that if there is a problem with the filler during installation, it can be discussed with the manufacturer accordingly. In addition, you can also see if there is an anti-theft keel lining in the security door. Theft-proof keel generally has two kinds: grid shape and S shape. S-shape saves material, but its strength is not as good as that of grid. Look carefully when you buy it. If there is no anti-theft keel inside, the anti-theft performance will be greatly reduced. Third, check the thickness of the steel plate. It is understood that the surface of the security door on the market is made of steel plate, but some manufacturers have tampered with the steel plate. And because ordinary consumers can't tell the quality of steel plates, writing articles is more hidden. One is to make a fuss about the thickness of steel plate. According to the national regulations, the thickness of the steel plate of the security door should be above 1 cm, but the thickness of the security door made by some small workshops can not be reached at all. Some are as thin as snowflake boards made of chimneys, and the thin boards lose the meaning of anti-theft and can be pried open with hard objects. The second is to use hot-rolled plate instead of cold-rolled plate. The steel plate of the security door should be cold rolled. Because cold-rolled sheet has good ductility and toughness, but the price is more expensive, some manufacturers switch to hot-rolled sheet in order to save costs. A good security door steel plate should also be galvanized or phosphatized inside, not just painted on the surface, so that the steel plate is not easy to be corroded.
Remedial measures for paint scratches on security doors can refer to the information compiled by Xiaobian above for everyone. We can either go to the related stores to buy ordinary color automatic paintings for reprocessing, or take simple and practical methods such as buying interesting and suitable stickers to remedy them. Of course, the choice of different ways needs to refer to the actual scene. If it can't be solved, you can also turn to professionals and refer to the methods and measures provided by maintenance personnel or after-sales service for a series of operations.
