The acceptance of rough houses is a link that many owners have neglected. The acceptance of rough houses is of utmost importance. Do not neglect the simple and necessary acceptance of the entire room because you are too happy with the new house keys or other reasons. The acceptance will directly influence whether or not the decoration company after you can smoothly carry out and complete the high quality. 1. Electricity—In the construction inspection and acceptance of the house, it is necessary to check whether each room has electricity. Each room has a simple light bulb to see if they are all normal. The outlets in each room must not be forgotten. It is not very expensive to sell simple electroscopes on the market. We can use test pencils to test whether each outlet has electricity. If you don't have a test pencil, you can use the soil method and use a mobile phone charger or hair dryer. 2. Water—In the rough room, toilets and kitchens are well-routed water lines, but most of them do not have water taps. We can take a bucket of water and pour it into the pipeline to see if the water is blocked or not. If you hear the sound of the water, you can say that the water is very happy. The floor of the bathroom should be well waterproofed, but it is impossible to do a water-blocking test because of the conditions during the inspection. Therefore, we must let the decoration company do a water-blocking test before the renovation and look for water leakage after 24 hours. 3. Ventilation System—The ventilation system is a big issue that is easily overlooked during inspections. Flues and exhaust ducts are places that are easy to leave hidden dangers for daily life. 4. Doors, Windows—The door is the most easily forgotten place. The owner is pleased to open the door with the key. The main concern is to see what the house looks like, and what the door looks like and how it looks. After being left behind, such a process is absolutely undesirable. Now the houses are installed with anti-theft doors. After opening the door, you should carefully observe and touch the surface of the door by hand to see if it is flat and there are no scratches or areas that have been impacted. Look at the door frame visually, because the door frame is not correct. Will directly affect the use of your actual life in the future, but also should try to lock back and forth to see if the normal opening, closing, if you encounter problems to timely reflect the property to be replaced. 5. Wall and floor—In the inspection and acceptance of the rough house, the wall and the ground are the largest and most critical areas. We must check whether the walls of all rooms are flat or whether the floor of the kitchen or bathroom is empty. If the unevenness of the wall will cause a lot of trouble for the decoration in the future, the unevenness of the ground will also affect the later paving or laying of the floor. If there is a hollow area in the wall of the bathroom and the kitchen, it will be easy to fall off after the decoration is attached to the tile. In order to avoid and early detection of these problems, we can use some lively, easy-to-use methods of earth testing to find a longer bar on the wall and see if the bar is attached to the wall, if there is 1 - The error of 2mm is within the scope of the national standard. If the error is large, the property must be hired to pick up the worker to rehash the wall. We can also take the book and use one of the 90-degree right angles against the corner to see if it is perpendicular to the 90-degree angle of Yin Yang. To see if there is an empty drum on the wall, you can use a small hammer to test and judge whether there is empty drum on the wall by sounding when you tap.

Winter house decoration teaches you how to minimize the risk of paint
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
