Tile stone is more common in decoration, so it is very affecting the appearance when it is yellowed in use. How to deal with the yellowing of tile stone in the ordinary practice? Let's take a look at the four tricks of Xiaobian.
The decoration of the kitchen and bathroom of the modern family generally uses ceramic tiles or some stone materials. It is not only simple and generous, but also can make rational use of the only space, and make the storage cabinets on the inner wall. However, from the technical level of the current decoration industry, after the ceramic tile stone has been used for a period of time, it will appear loose and fall off. The main technical reason is that the viscosity of the cement mortar is not enough. Moreover, the kitchen is often eroded by greasy and rust, and the bathroom is in a humid environment for a long time, facing the erosion of rust and scum, and the tiles and stone are prone to yellowing. In order to keep the porcelain surface clean without damaging the porcelain surface, you can use a multi-purpose decontamination cream to clean.
As for the gap between the tiles, you can use a brush to remove a little dirt to remove the dirt, and then brush a waterproof agent in the gap, so that it can not prevent water seepage and prevent mold growth. It is worth mentioning that the cleaning and disinfecting agents used in large quantities in the home contain chemical substances such as acid and alkali that have a great influence on natural stone, which adversely affect the color and internal mineral composition of the stone. What is especially serious is that most detergents must react on the surface of the stone for at least five minutes to have an effect. However, during this time, the cleaning agent is already destroying the stone, so the surface of the stone for cleaning the bathroom should be neutral. detergent.
The acidic cleaner removes the limestone, cement stains, scales and the intractable urine stains and oxidized metal stains commonly found in the bathroom, such as acidified cleaners. Alkaline cleaner removes all kinds of animal and vegetable grease stains and mechanical oils, and removes the wax layer on the ground. Such as special strengthening oil cleaner; strong waxing water. If the acid-alkaline cleaner is used improperly, it will cause the waste of the detergent, and it will damage the surface of the cleaning object to varying degrees, and may even cause damage to the skin or eyes of the user.
Therefore, we should pay attention to the following points when using acid-acid detergents:
1, to be clear about its use and contraindications, should read the instruction manual before use, or consult the supplier for detailed instructions.
2. Before use, make a small sample experiment in an inconspicuous place, confirm that it will not cause damage to the cleaning object. Use a clear dilution ratio to dilute the cleaning solvent. Wear work gloves when working, and wear eye mask if necessary.
3. Avoid contact with the skin or eyes. The cleaning agent should not stay too long on the surface of the cleaning object. After use, clean it with clean water.
4, can not be used on the surface of objects sensitive to acid and alkali, such as some cleaners for Dali
Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
