Problem 1 wire installation socket fever When installing electric sockets, switches and lamps, electricians do not wire according to construction requirements. In particular, when consumers use some electric appliances such as water heaters and air conditioners that consume large amounts of electricity, the switches and outlets are heated and even burned, causing great losses to consumers. Reminder: In the construction supervision of the electrician in strict accordance with the operating procedures for construction, after all switches, sockets installed, be sure to look at whether these parts have a fever. Problem 2 Paving Problem Tiles Falling Paving tiles are a highly technical process. If you cut corners, the most likely problems are the emptying of tiles, the use of cement and adhesives for paving tiles. If the mix is ​​unreasonable, there will be problems such as shedding. Reminder: The “Quality Acceptance Criteria for Family Room Decoration Projects†requires that tile and floor tile should be flat and firm, with clear patterns, no dirt and no traces, and the same surface color, uniform joints, no cracks, missing corners, and missing edges. Hollowing must not exceed 5% of the total number. Problem 3 Wall Slotted Wall Cracking The buried pipeline must be slotted on the wall and ground in order to bury the pipeline. A few workers perform barbaric construction during the grooving operation, which not only damages the building load-bearing structure, but also may cause damage to other nearby pipelines. Reminder: Before construction, we must reconfirm the direction and location of the pipeline with the construction team leader. For different wall structures, the requirements for slotting are not the same: the walls of the load-bearing wall in the house are not allowed to be slotted, and the wall with the insulating layer is easy to cause cracking on the surface after being slotted, and on the ground Slotting, but also be careful not to damage the floor, causing trouble to the residents downstairs. Question 4 Ground Leveling Hazards to Buildings Some houses are not well-grounded and need to be renewed Leveling. If the workers are not careful or intentionally sloppy, it will cause the problem of “more and more unevennessâ€, and the cement mortar used in construction will also greatly increase the ground load, causing hidden dangers to the safety of the building. Reminder: Before ground leveling, ground surface treatment must be done first, and then use cement mortar to level the ground. After the cement is dry, determine the flatness of the entire floor using a dedicated level ruler, and then proceed to the next step. Question 5 Electric hazards caused by wearing electric wires In home renovation construction, almost all wires are put in PVC pipes and buried in the walls. If the worker is not careful in the operation, it will cause the wire to kink in the tube, causing electricity hazards. If workers intentionally cut corners, they would use wire with connectors or put several wires in the same PVC pipe. Reminder: It is best for consumers to purchase the wires themselves, and then supervise the operation of the workers at the site. After the installation is complete, a power-on inspection is required to allow the decoration company to leave a “pipeline diagramâ€. When the electrician had just buried the wires in the wall, he could number the walls and draw a floor plan. Then he used the strokes to draw the direction of the wires and the specific location of the wires, indicating the position on the floor, the ground and the adjacent wall. In particular, the position of the joints of the pipelines should be marked so that in the event of a fault, the line position can be found immediately. Question 6 facet processing easy to leave dead corner The so-called “small face†is a small place that some consumers can't see and don’t pay much attention to, such as the upper edge of the door, the underside of the window sill, the inside of the heating cover, and so on. Some workers will cut corners here and there, even Without any treatment, it is easy to form a pollution corner. Reminder: Any object has 6 planes. Don't ignore any details when checking quality. Problem 7 seam decoration paint peeling off In some places where the wall meets the door and the window, and where the two different colors of paint meet, it is also where the workers often perfunctory. You will often see mixed paints between latex paint and wood, and various problems such as paint peeling at joints. Reminder: It is very important to deal with joints. You must supervise the workers to do serious construction. If there are two colors of paint on the wall facing each other, it is necessary to apply adhesive tape on the edge of the first color during construction, and then apply another color of paint on it, so that the construction is completed. After tearing off the tape, the entire seam can be very neat. Problem 8 Substrate Treatment Wall Color Difference Before applying latex paint and applying tiles, be sure to handle the substrate. Some workers cut corners and cut materials in this regard during construction, and the unevenness caused uneven wall surface. After the paint is applied, there is a color difference. When the paint is applied, the paint is discolored and peeled off, or the ceramic tile is not firmly bonded. Reminder: In the paving construction of tiles, you should pay attention that the tiles can not be directly laid on the surface of lime mortar, lime paste, paper lime plaster, hemp stone mortar and latex paint. layout. Bonding pastes used between tiles and substrates should be formulated in strict accordance with the construction standards and proportions, using the specified grades of cement and adhesive materials, and they cannot be randomly deployed. When applying latex paint, be sure to pay attention to whether the application of the wall putty is even and smooth, whether the sanding and roller coating are in place. Also pay attention to whether the latex paint is properly proportioned. Entrance decoration Children's room Decoration Paint Lacquer Paint Cement Socket Floor tile Tile Floor tile Inconel, when heated, forms a thick yet stable oxide layer that protects its outer surface from further attack. This makes it the ideal choice for extreme temperature and pressure applications, where steel and aluminum would succumb to thermal creep. Available in numerous grades, the Inconel alloys exhibit shifting characteristics with slight variations in their chemistry.

In its more basic form, typical applications would include the food industry and heat treatment components. When alloyed with other elements, however, further strengthening and stiffening permits its use in the more demanding areas of the marine, aerospace and chemical processing industries. Alloyed to its peak performance, Inconel then becomes the material of choice in the most critical environments of turbine blades, rocket engines and key nuclear industry components.
Said that the decoration market, the water is too deep, a lot of friends reflect the renovation, until the decoration half he found that building materials to buy expensive, decoration team to find the wrong, the construction progress is too slow. In order to build a warm home for oneself, one can only work as a supervising person, decorate it during the study, and find quality problems in the decoration. However, there are some decoration problems he did not find, that is, decoration workers cut corners caused by cutting corners, unclear television signals and other quality problems to bring a lot of inconvenience to life. The following author will introduce you to some of the problems often encountered in the decoration process, friends plan to advance to prevent it!
