PVC board ceiling material is made of PVC resin as the base material, adding a certain amount of anti-aging agent, modifier and other additives, through mixing, calendering, vacuum blistering and other processes.
The utility model has the advantages of light material, simple installation, water-proof, moisture-proof, moth proof, and many changes in the color and pattern of the surface, and has the good performance of pollution resistance, good cleaning, sound insulation and heat insulation. In particular, the flame-retardant material is added to the new process to make it more safe to use.
Compared with the metal ceiling plate, the disadvantage is that the service life is relatively short.
Installation and construction technology of PVC board ceiling materials
1. preparation of materials and machines
Material preparation:
Light steel keel, fittings, suspenders, expansion bolts, PVC plates, etc. are qualified in mobilization inspection, and whether there is factory certificate and material quality certificate.
Machine preparation:
Profile cutting machine, electric curve saw, electric hand drill, electric hammer, self tapping screw drill, portable electric sandpaper machine, etc.
Within the required ceiling range, the mechanical and electrical installation has been completed, all pipelines have passed the pressure test, and have passed the concealed acceptance.
The positions of lamp positions, vents and various lighting orifices have been determined. Before the installation of the ceiling cover panel, the wall, ground and wet works shall be completed. Set up the roof construction operation platform frame.
Before large-scale construction of the light steel framework ceiling, a sample room shall be built to carry out structural treatment on the camber, lamp slot, curtain box, air vent, etc. of the ceiling, and large-scale construction can be carried out after identification.
