The suspended ceiling is composed of decorative panels, keels, suspension wires and other materials, which can be replaced frequently as needed. This is a very convenient household item. According to the different materials of the decorative board, the ceiling can be divided into gypsum board ceiling, metal board ceiling, glass ceiling, 4x8 pvc foam board ceiling and so on. Gypsum board is relatively cheap, followed by PVC board, and metal board is the most used but the price is higher. At present, aluminum gusset ceiling is the main application in home improvement.

But pure aluminum is relatively soft, so the aluminum gussets on the market are actually suspended ceilings made of aluminum alloys, including aluminum-magnesium alloys and aluminum-manganese alloys. The aluminum-manganese alloy gusset has high hardness, and the aluminum-magnesium alloy increases the hardness while also increasing some brightness. Good texture and strong decorative function. High-quality aluminum-manganese alloy gussets are commonly known as stainless steel aluminum due to their good corrosion resistance. PVC board manufacturers
Special note: There are some defective substrates on the market, which are made of scrap aluminum, secondary aluminum or mixed aluminum. Products are easily deformed and oxidized, and some are recycled aluminum, containing chromium, lead, mercury and other harmful substances. This aluminum buckle base material is low in price, high in hardness, and has a certain thickness, which is very deceptive.
PVC board production value and consumption. PVC board use
The output value and consumption of PVC sheets are 1.4 million tons, and PP sheets are being produced and used in the entire international plan at a rate of 4%. In recent years, polyvinyl chloride plastics have been added many times in Southeast Asia. This is due to the urgent need for infrastructure construction in Southeast Asian countries. Polyvinyl chloride plastic board is the most suitable material for producing three-dimensional outer coating film. PP sheet specific gravity: 1.38 g/cm3, molding shortening rate: 0.6-1.5%, molding temperature: 160-190℃. PVC board strength
Pvc board features: excellent mechanical properties, excellent electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. It is suitable for manufacturing thin plates, wire and cable insulation layers, seals, etc.
