Three Elements of Stainless Steel Door Installation

1. before installation

Please use glass glue in the welding position of the back mounting hole, main lock body, auxiliary lock, reaming hole, 45 degree angle and 30 wrap edge.

2. installation time

A. Dry grouting, not wet grouting, top frame blowing foam;

B. Strip installation as far as possible and avoid punching installation holes.

3. after installation

A. Inspect immediately whether the cement slurry water penetrates into the surface of the board. If you have any, tear off the protective film at the first time, let the air circulate, remove it immediately, and avoid alkaline substances such as cement slurry corrosion to the surface of the board. Pay special attention to the bottom of the door frame near the ground, which is vulnerable to pollution and corrosion.

B. Wash it with clean water in time and dry it with dry cloth.

C. For example, after the door is installed, other parts, such as the outer wall, are not fully completed. Pay attention to the protection of the later decoration process, such as wall wash water should not be touched on the door panel, etc.

Common sense of daily maintenance: "There are ways to prevent rust and magic tricks to remove rust"

1. Keep the board clean and prevent the board area from gathering too much dirt. Please clean the board surface with clean water from time to time or after typhoon. When residual oily substances or daily detergents are attached to the board surface, please wipe it with a soft and clean cloth, and then wash it with neutral detergent or ammonia solution or special detergent. It is forbidden to use acid and alkali detergents and clean the back frame in time after sticking bricks.

2. For the coastal residents, because of the high salt content in sea breeze, the surface of the color plate will change color when it is rusted by standing order, and the effect is not good. Clean the plate with clean water at least once a week to prevent the sea water from eroding the surface. If the rust is serious, we can use sandpaper to surface the rusty color board door, then use automobile paint (according to the color of the paint) and air compressor spray paint treatment.

3. Rainbow lines on the surface of stainless steel are caused by excessive use of detergent or oil, which can be washed away with warm water or neutral detergent.

4. Rust caused by stainless steel surface contaminants can be washed with 10% nitric acid or abrasive detergent.

5. In the ordinary use process, the door should be opened and closed slowly, so as to avoid the damage of stainless steel door protective layer caused by collision with other sharp and sharp things.

6. When using stainless steel doors in humid environments, attention should be paid to the accelerated oxidation and rusting of stainless steel doors due to long-term dampness. Because of the high humidity in this environment, it is easy to accumulate dirt and mildew.

Taboos in Processing and Manufacturing

1. When WEDM, the cutting oil should be cleaned in time.

2. Avoid the second stamping when stamping the sheet. When the worker is not skilled enough, it will lead to cracks or rupture of the sheet at the bending point.

3. Bishun uses fingerprint-free process, because fingerprint-free oil will form an excellent protective layer on the surface of the plate, which can effectively isolate various environmental pollution and erosion.

4. The normal width of the edge plate is less than 1219 mm, and the edge part can not be used.

5. Industry process problems, there will be color difference between different panels of the color plate, the operation of the folding plate must be before the color can be cut, and the same board from different angles will also exist different colors, pay attention to the same direction when butting the plate, that is, the horizontal and vertical alignment.

6. When shearing and pressing, avoid the hydraulic oil remaining on the board, and clean it in time. Because of the strong permeability of hydraulic oil and the limited anti-permeability ability of the protective film, hydraulic oil can easily penetrate into the plate surface through the protective film, causing rust or discoloration.

7. Store finished products (such as well-made doorframes), pay attention to check whether the protective film is damaged, timely sealing, to avoid the surface exposed by the outside wet air infiltration, corrosion plate surface, causing discoloration. The ground for storing finished products should be kept dry to avoid discoloration caused by long-term contact with the ground and moisture infiltration into the floor.

Notes on Processing, Installation and Use of Stainless Steel Color Series Plates

1. Do not tear, scratch or scratch the surface protective film before processing and installation to prevent damage to the plate surface without fingerprint oil film, resulting in color change due to oxidation.

2. After processing and installation, please tear off the protective film in time. If it is found that there is slight gel loss or surface contamination, it is strictly forbidden to wipe with chemical agents such as toluene, acetone, alcohol, Tiannashui, diluent, etc. in order to prevent chemical reactions between chemical agents and fingerprint-free oil film, resulting in serious consequences such as discoloration and oxidation discoloration. In such cases, only a clean towel soaked in clear water can be gently wiped.

3. In the process of installation, when cement and glass glue must be used as little as possible or not, they must be gently wiped with a wet towel before the cement is dried and solidified. It is strictly forbidden to scrape back and forth during the wiping process to prevent cement sand from scratching and scratching the surface causing serious consequences. If the cement has been solidified, do not use hard knocking, stabbing and other violent ways to deal with, as long as timely and even tore the protective film together. When using glass glue on color plate, do not tear off the protective film, but put the glass glue on the protective film. When there is glass glue on the outer surface of the board, gently wipe it off with a clean dry towel before the glass glue is dry.

4. The stainless steel plate of color series can not be directly welded or cut by high temperature tools such as oxygen welding, argon arc welding and electric welding. After the protective film is torn off, a layer of fingerprint-free glossy oil film is sprayed around the hole to protect against oxidation.

5. After the finished stainless steel plate of color series is made, in the process of transportation, handling, installation and use, if the surface of the plate is damaged, please immediately spray with fingerprint-free oil film to protect it.

6. For example, in the processing, installation and use of stainless steel sheets of color series
