Introduction of Drywall Screws, Gypsum Screws
Drywall screws are a kind of self tapping screws that used to install the drywall on walls or ceillings which are generally wood or metal framing members. For wood walls or ceillings, always using the coarse thread drywall screws, and for sheet metals or plasterwood walls, normally using fine threaded drywall screws ordrywall tek screws (with a drilling point).
Why need a drywall screw to install drywalls on a wood/metal walls or ceilling?
Firstly we shall know Drywall is a type of building material that made from gypsum and other minerals pressed between sheets of heavy paper. Using a drywall screw, there is no need to pre-drill holes, with its counter sunk head design (always in Phillips drive), the screw lies flush with the surface of the sheet, creating a smooth and even finish. It can minimize dimpling on the face of the walls while other nails may leave small holes in or divots in the drywall, and even goes loose over time. Drywall screws are threaded to grip both the drywall and the framing members tightly, and provide a much more secure and long-lasting installation over time. The countersunk head also helps prevent the drywall screw from breaking the paper surface. Drilling a drywall screw must have a tool known as drywall dimpler, which has an adjustable nose that can avoid tearing the paper on each sheet. After all the screws have been installed, the walls are finished using joint compound which is spread over both the screw holes and the joints between each sheet. Once the compound dries, the walls can be sanded smooth and painted.

Drywall screws are always come with black phosphated or zinc coated which helps to minimize rusting and corrosion as the screws are exposed to wet joint compound or paint.

Oxide Ceramics Powder

Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.

Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.

Some common types of oxide powders used in thermal spray include:

1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.

2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.

3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.

4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.

These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
