The renovated room can't be checked in immediately. It should be ventilated and scented as much as possible, but it can't open all the doors and windows to ventilate, because it may bring disadvantages to the wall top paint just after construction, make the wall top quickly dry, prone to cracks and damage the appearance. . So, how to effectively remove the newly decorated paint smell in the room?
1, you can go to the market to select some high-tech smelly detergent, it can remove the harmful gases emitted by newly renovated rooms, new furniture. According to relevant sources, these astringent detergents are generally imported products, which use chemical reaction of ammonia compounds with harmful substances, thus playing a role in cleansing. In the newly renovated room, the astringent detergent can be poured into the tray, and the trays are placed in each room, and combined with the scrubbing method, the unpleasant smell can be effectively removed after several days.
2, the most affordable and landscaping method is of course to put the right flowers at home. Plants that can absorb formaldehyde are cactus, spider plant, gerbera (also known as gerbera), reed, ivy, iron tree, chrysanthemum and so on. The flowers and plants that eliminate xylene include ivy, iron trees, and chrysanthemums.
3, to quickly remove the residual paint smell, citric acid soaked cotton balls, hanging indoors and wood furniture.
4. Two bowls of salt water can be placed indoors, and the paint smell will be quickly eliminated. If it is the smell of paint from wood furniture, it can be scrubbed several times with tea, and the paint smell will be eliminated faster.
5, the container is filled with cold water, then add the right amount of vinegar in a ventilated room, and open the furniture door. In this way, the amount of water can be evaporated to protect the top coating surface, and the residual odor can be absorbed.
6, placed in the room with orange peel, lemon peel and other items, is also a very effective way to taste, but they will not be very effective.
7, newly renovated houses often have a variety of pungent chemical raw materials such as Tianna water, a broken open jackfruit (a tropical fruit shaped like durian, but not a durian!! Put durian can be bad !!) In the house, because the jackfruit is large (usually as big as watermelon), the aroma is very strong, and the odor can be absorbed in a few days.
8, buy some pineapples in each room put a few, large rooms can put more. Because pineapple is a crude fiber-like fruit, it can absorb the smell of paint and achieve the clear fragrance of pineapple, speed up the removal of odor, and achieve the best of both worlds.
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.
