Gypsum board ceilings are popular among consumers because of their low price, varied shape and flexible form. It is a common type in home decoration ceiling decoration. However, some owners found that there was such a problem in the gypsum board ceiling after the check-in. Xiaobian selected four questions with high probability of occurrence, and found a professional to answer, let's take a look!
Question 1: What should I do if there is a large area collapse of the gypsum board ceiling? What is the reason?
Experts answer: The collapse of the large surface of the ceiling is a problem with the keel connector. The collapse of the ceiling is mostly because the main keel does not sink, and the secondary keel sinks. The most fundamental reason is that the connection between the main keel and the auxiliary keel is small, and the installation method is not proper when the construction personnel are installed, resulting in the keel connection not being in place.
Question 2: What is the cause of the water ripple after the plasterboard ceiling and the putty paint?
Experts answer: There are three reasons why this phenomenon can occur after the plasterboard ceiling is painted:
1. The flatness of the wall surface is not up to standard, and the unevenness of the bottom surface after the painting is applied affects the surface.
2. The quality of the latex paint used is unqualified, the adhesion of the fake and shoddy latex paint is insufficient, the fluidity of the paint surface is increased, and water ripples are formed during the drying process.
3. In the case of no problem with the product and the wall surface, the paint surface forms a water ripple. It can only be said that the latex paint is not evenly mixed or the proportion of water is not correct during the watering process.
Question 3: In the south, is the living room ceiling covered with cement or gypsum board?
Experts answer: The air in the south is humid, the gypsum board ceiling itself is not moisture-proof, but it is not impossible to make a gypsum board ceiling. Just put a waterproof putty on the gypsum board, or buy a waterproof gypsum board with oil. Putty can play a moisture-proof effect. Keep in mind that the gypsum board ceiling cannot be used for the ceiling of the bathroom, because the water vapor in the bathroom is too large and exceeds the moisture limit of the gypsum board. The cement board is generally used as a partition wall material in the bathroom, and is not suitable as a material for the living room ceiling.
4: How can the home improvement gypsum board ceiling completely eliminate cracking? Is it better to use good kraft paper than kraft paper?
Experts answer: There are many reasons for the cracking of the ceiling. For example, the selected position of the expansion bolt of the fixed lifting rib is incorrect, the false point of the lifting point and the hanging node is abnormal, the spacing of the self-tapping nail of the fixed plasterboard is too large, or some self-tapping screws are falsely received. It is also possible that there is a problem in the construction process of the caulk and the adhesive tape.
As for the use of kraft paper or a good cloth to prevent cracking, this depends on the specific circumstances. Kraft paper is to increase the rigidity of the gypsum board, and the good cloth is to increase the flexibility of the gypsum board. The most important thing is the process of applying the cloth or paper. How to cut the gypsum board and how to fill the putty is the key point.
Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
