alert! Decoration security risks!
Home decoration people often pay attention to the surface of the luxury and beautiful, but the safety of the decoration is easy to ignore, resulting in accidents are not individual. In general, the following points should be noted in the renovation project: >>>Links: The Most Easily Ignored Security Problem in Kitchen Renovation First, do not install marble on the floor of the house. Because marble is dozens of times heavier than floor tiles and wooden floors, if the floor is entirely covered with marble, it can overwhelm the floor. Especially for floors above the second floor, the weight of the floor decoration material must not exceed 40 kg/m2. Second, the balcony, bathroom decoration should try to use a small load of material, to prevent the bearing weight is too large. Third, before decorating the toilet room, first stop the floor drain, put 5 cm deep water, and conduct the watering test. If it leaks, it must be re-made waterproof; do not leak, but also carefully laying the ground in the construction, do not damage the waterproof layer and arbitrarily change the water and heating system. 4. When decorating, do not casually wear holes in the load-bearing walls, and do not remove the walls connecting the balconies and doors and windows, and enlarge the size of the original doors or windows or build additional doors and windows. Because this will cause partial cracks in the building and seriously affect the earthquake resistance, thus shortening the life of the building. Fifth, for the pursuit of luxury, the four walls are covered with plates, and the ceiling is inlaid with two or three layers of three-dimensional ceiling. This practice not only reduces the size of the entire space and creates a sense of repression, but it is not costly for fire protection. 6. When using wires, avoid using aluminum wire with copper wire. It should also be noted that it is not possible to dig trench-embedded wires directly on the walls, and regular bushings should be used to prevent leakage and fire. 7. Care should be taken to avoid holes, holes, hanging ceilings, and installations of art lighting fixtures in concrete slabs. VIII. The decoration shall ensure the safety requirements for gas pipelines and equipment, and the pipelines shall not be arbitrarily dismantled. It should be noted that the net distance between the power line and equipment and the gas pipeline should not be less than 10cm, and the crossover between the wire and the gas pipe should not be less than 3cm. 9. Don't put the gas stove on the wooden cabinet in the kitchen decoration, and you can't wrap the gas valve in the wooden cabinet.

The ease of use of the pipette and the pipette holder also affects the ease of experimental operation.
