Retractable Window Screen

What Is a Retractable Window Screen?

A retractable window screen is a screen that can be installed on windows or doors and is capable of opening and closing.

It is used to block insects and dust from entering while allowing natural airflow into the interior. Typically, it is mounted on the frame of windows or doors and can be retracted as needed. Retractable window screens can be manually retracted when opening or closing windows or doors, allowing them to be used only when necessary. This allows for neat storage when not in use or when the screen is desired to be closed, preserving an unobstructed view of the outdoors.

They are used not only in residential settings but also in office buildings, commercial facilities, hotels, stores, and more.

Pressure Sensitive Adhesive

What Is a Pressure Sensitive Adhesive?

Pressure sensitive adhesive, also known as PSA, is the adhesive applied to adhesive tapes.

It is a special adhesive that exhibits adhesive strength when pressure is applied. Generally, it provides sufficient adhesion with just a touch, and it does not require additional processing such as heat or solvent, making it convenient to use. PSAs are used in adhesive tapes, labels, stickers, Post-it notes, and more. These products contain pressure sensitive adhesive thinly coated on substrates such as paper or film, allowing them to be quickly applied by applying pressure when needed.

Pressure sensitive adhesives are composed of a combination of polymers such as acrylic polymers, rubber-based polymers, and silicone-based polymers, as well as additives such as plasticizers to improve flexibility and elasticity, antioxidants, UV stabilizers, and thickeners.

Preamplifier

What Is a Preamplifier?

A preamplifier, also known as a preamp, is a device used to amplify or convert audio signals or electrical signals.

It is also referred to as a preamplifier or head amplifier. It performs functions such as signal amplification, which involves receiving low-level signals and boosting them to larger signals, signal selection from multiple input signals, and frequency adjustment to emphasize or attenuate specific frequency bands to adjust acoustic characteristics and improve sound quality or correct specific bands.

Preamplifiers are used in audio equipment such as home audio systems, professional audio equipment, instrument amplifiers such as guitar amps or bass amps, as well as integrated into studio mixers and audio interfaces.

Powercon

What Is a Powercon?

A Powercon, short for Power Conditioner, is a device that converts electricity generated by solar panels from direct current (DC) to alternating current (AC).

Electricity generated by solar panels is typically in the form of DC, whereas households and general power networks use AC power. Therefore, to use the DC power obtained from solar power generation for household purposes, it needs to be converted from DC to AC. This is the role of a Powercon.

The Powercon receives DC power from the solar panels and converts it into AC power suitable for households or power networks. In this process, the inverter controls parameters such as voltage, frequency, and phase to adjust the power obtained from solar power generation into a form suitable for the normal power supply network.

Planetary Gearbox

What Is a Planetary Gearbox?

A planetary gearbox is a device used to amplify or decrease the torque, which is a physical quantity representing the force to rotate an object.

It consists of three main components: the sun gear, the planet gear, and the ring gear. The sun gear is a gear positioned at the center, surrounded by planet gears, which mesh with both the sun gear and the ring gear. The ring gear is the outer gear with which the planet gears mesh and is responsible for power transmission to the exterior. These components interact to create multiple power transmission paths, allowing for changes in rotational speed and amplification or reduction of torque.

Planetary gearboxes are used in applications such as robot arms, conveyor belts, and automotive transmissions.

Pipe Inspection Camera

What Is a Pipe Inspection Camera?

A pipe inspection camera is a specialized camera used to visually inspect the interior of pipes or conduits.

These cameras are typically employed in industrial applications and construction sites to verify the condition and detect abnormalities within the interior of pipes. They feature flexibility to be inserted into both flexible and rigid pipes and can capture high-definition images of the interior. Additionally, they are inserted into the pipe under inspection and can transmit real-time images.

They are used for various purposes such as drain inspection to inspect foreign objects or damages inside sewer or drainage pipes, gas pipe inspection to visually inspect the interior of gas supply pipes for leaks or damages, and vent pipe inspection to examine the interior of building or facility vent pipes for blockages or damages.

NEMA Enclosure

What Is a NEMA Enclosure?

A NEMA enclosure is a standardized case or housing designed to protect electrical equipment and control devices.

NEMA enclosures are primarily a standard used in North America and are utilized to protect electronic equipment from external environments across various industries and applications. To accommodate different purposes and environmental conditions, there are various types and grades such as waterproof, dustproof, corrosion-resistant, and explosion-proof.

The types and characteristics of enclosures are based on standards established by NEMA. For example, NEMA 1 enclosures are suitable for general indoor applications and provide dustproofing but not waterproofing. NEMA 4X enclosures are suitable for outdoor or high-moisture environments and offer waterproofing, dustproofing, and corrosion resistance.

Horn Antenna

What Is a Horn Antenna?

A horn antenna is an antenna used for receiving or transmitting electromagnetic waves such as radio waves or microwaves.

Named for its shape, which typically resembles a horn or cone with flared sides or a widened tip, it is known as a horn antenna. Its horn-shaped structure allows it to efficiently receive or transmit electromagnetic waves and focus them in a specific direction. Key features include the ability to process signals over a wide bandwidth and high directivity, meaning it can strongly concentrate the reception or transmission of electromagnetic waves in a specific direction.

Horn antennas are primarily used in the microwave region and find applications in fields such as communication, radar, satellite communication, and wireless communication.

High Temperature Tape

What Is a High Temperature Tape?

High temperature tape is a specialized tape intended for use in high-temperature environments.

These tapes are made from materials with high heat resistance, capable of withstanding high temperatures. When used in high-temperature processes or environments, these tapes are expected to function without degradation. They are used in industrial applications for protecting high-temperature machinery components and piping, as well as for insulation and protection in environments where high temperatures are generated, such as electronic devices and automobile engines.

These tapes are typically made from heat-resistant materials such as silicone, fiberglass cloth, or aluminum. The heat resistance temperature of typical high temperature tape starts at over 300 degrees Celsius and can reach over 1000 degrees Celsius in some cases.

Flexible Pipe

What Is a Flexible Pipe?

A flexible pipe is a conduit or piping made of a material that is flexible and easily bendable.

It possesses elasticity and bendability, making it suitable for use in tight spaces or areas with many bends. It is utilized in household and industrial water supply and drainage systems, particularly as supply or drainage pipes buried inside walls or floors. Additionally, it is used for gas supply pipes for gas or propane where pressure resistance and flexibility are required, as well as in-vehicle fuel supply pipes, medical equipment, and industrial machinery.

Flexible pipes are typically made from materials such as metal, plastic, or rubber, and the appropriate material and specifications must be chosen based on the environment and purpose of use.
