keel
The materials used for the suspended ceiling are divided into wooden keel and light steel keel.
1. Wooden keel: also called wooden square, generally used for gypsum board ceiling and plastic steel plate ceiling.
2. Light steel keel: According to the different models, specifications and uses, there are T-shaped, C-shaped, U-shaped keels, etc., which are generally used for aluminum gusset ceilings and integrated ceilings.
Water pipe fittings
1. PPR pipe: PPR pipe has outstanding physical properties. It is non-toxic, light, pressure-resistant, and corrosion-resistant. It is not only suitable for cold water pipes, but also for hot water pipes, and even pure drinking water pipes. The interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together, so once the installation pressure test is passed, it will not exist for a long time to age and leak like the aluminum-plastic pipe. In addition, the price of the PPR pipe is low and the installation is convenient, so it is currently widely used as a home improvement water supply pipe.
2. Inner wire and outer wire: connectors for connecting faucets, water meters, and other types of water pipes.
3. Angle valve: Also called stop valve, it is a water component used to control the water output between the water outlet point on the wall and the soft connection.
4. Soft connection: also known as hose, a water piece used to connect between the faucet and the water outlet.
Various types of glue
1. Glass glue: It is used to bond cabinet countertops and kitchen walls, fix basins and toilets, etc., as well as caulk and fix in some places. The categories include acid glass glue, silicic acid neutral structural glue, silicone stone glue, neutral anti-mold glue, bathroom anti-mold special glue, etc. Consumers should choose glass glue according to specific purposes.
2. Styrofoam: When the material is sprayed from the aerosol can, the foamy polyurethane material will expand rapidly and react with the air or the moisture in the contacted substrate to form a foam. The cured foam has multiple effects such as caulking, bonding, sealing, heat insulation, and sound absorption, and can be applied to sealing and plugging, filling gaps, fixing bonding, heat preservation and sound insulation.
Ceramic tile accessories
1. Pointing agent: also called caulking agent, specially used to fill the gap between tiles. Grooving agent is a dry powder material composed of white cement as the main material, adding a small amount of inorganic pigments, polymers and trace antibacterial agents.
2. Jointing agent: an upgraded product of jointing agent, its composition is polymer and pigment, which has the characteristics of anti-penetration and waterproof.
3. Tile locator: Also known as a cross, it is an auxiliary tool used to fix the size of the tile gap.
