A flame arrester (also spelled arrestor), deflagration arrester, or flame trap is a device that stops fuel combustion by extinguishing the flame.
A flame arrester (also called a deflagration arrester) functions by absorbing the heat from a flame front traveling at sub-sonic velocities, thus dropping the burning gas/air mixture below its auto-ignition temperature: consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element. These channels are chosen and measured as the MESG (Maximum Experimental Safe Gap) of the gas for a particular installation. These passages can be regular, like crimped metal ribbon or wire mesh or a sheet metal plate with punched holes, or irregular, such as those in random packing.
Principle
Flame arresters are passive devices with no moving parts. They prevent the propagation of flame from the exposed side of the unit to the protected side by the use of metal matrix creating a torturous path called a flame cell or element. All detonation flame arresters operate on the same principle: removing heat from the flame as it attempts to travel through narrow passages with walls of metal or other heat-conductive material, but unlike flame arresters, detonation flame arresters must be built to withstand extreme pressures that travel at supersonic velocities, 1,500 psi (10 MPa) at 2500 m/s is not uncommon with a group D Gas.
Sintered metal flame arresters are designed to prevent the propagation of flames in gas or vapor handling systems. They are typically composed of cylindrical housing with a sintered metal element inside. The element is made up of multiple layers of metal powder that are compressed and sintered (heated without melting) to form a porous material with precise pore sizes and distribution.
When a flammable gas or vapor mixture passes through the flame arrester, the element acts as a filter, allowing the gas or vapor to flow through while trapping any flames or sparks. The porous material of the element also provides a large surface area for heat dissipation, making it difficult for any trapped flames to ignite the surrounding atmosphere.

Features
Effective flame arrestation: The porous material of the sintered metal element acts as a filter, allowing gas or vapor to pass through while trapping any flames or sparks. This helps to prevent the risk of fire or explosion in industrial settings where flammable gases or vapors are present.
Precise flow control: The pore size and distribution of the sintered metal element can be tailored to control the velocity and direction of gas or vapor flow. This allows for precise flow control, which is important in many industrial applications.
Durable and long-lasting: Sintered metal flame arresters are made from high-quality materials that are designed to withstand harsh industrial environments. They are typically very durable and long-lasting, providing reliable flame arrest for many years.
Low maintenance: Sintered metal flame arresters require minimal maintenance, making them a cost-effective solution for many industrial applications. Regular inspections and cleaning can help ensure that the porous element remains free of debris and in good working condition.

Application
Oil storage tanks are commonly used to store crude oil, refined petroleum products, and other flammable liquids. In order to prevent the risk of fire or explosion, flame arresters are often installed on the vents of these tanks.
When the tank is filled or emptied, a mixture of air and flammable vapors is released through the vent. If a flame were to ignite this mixture, it could cause a catastrophic explosion. However, by installing a flame arrester on the vent, the flammable vapors are filtered through the sintered metal element, preventing any flames or sparks from passing through.
In addition to storage tanks, sintered metal flame arresters are also commonly used in pipelines that transport crude oil, refined petroleum products, and other flammable gases or vapors. They can be installed at various points along the pipeline to prevent the propagation of flames in the event of a fire or explosion.

Low Melting Point Polyester Chip for Hot Melt Yarn Masterbatch
Extrusion Grade Polymer for Hot-melt Adhesive Glue Coating
Description:
Generally speaking, the low melting point polyester chip refers to one specialty polymer with a melting point between 90 and 220.
The melting point of polyester is the temperature at which a solid crystalline substance changes from a solid state to a liquid. So it reflects the purity of polyester. Generally speaking, pure polyester is a partially crystalline polymer with a melting point of 265. But during actual production, some impurities exist in the polyester due to various side reactions. At the same time, the defects of polymer crystals and the difference in crystallinity will also affect the melting point. The common type of low melt polymer is 110. But we can also offer a melting point of 90, 120, 160, and 180.
Application:
Low-melt polyester chips can produce low-melting point fiber, low-melting point synthetic fiber, and thermal-melting mucilage. Its primary usage is acting as bonding fiber in nonwoven fabrics. The end usage lies in clothing, articles for bed, shoe uppers, sleeping bags, sofas, and hygiene products.
LM PET Chip is also the main raw material of masterbatch carriers. That is, low-melt PET chips, conventional chips, and dyes are mixed to produce the polyester color masterbatch according to a certain proportion. The production of this product is the introduction of polyester macromolecules into the modified copolymer unit. And its melting point is in the range of 100-120. Commonly used modifiers are phthalic acid, adipic acid, and trimethylolpropane.
Recently, LM Polymer is also extruded into the back coating of nonwoven, automotive interiors, foam, injection molding, PET sheets, and hot-melt adhesive/glue.
Low Melt Yarn is also called hot melt yarn or fusible yarn. There are sheath-core low-melt bicomponent yarn and full low-melt polyester yarn.

-White Charcoal, also known as Binchotan, is a type of hardwood charcoal that has traditionally been produced in Japan. It is called White charcoal because of its light color and unique benefits that create economic value compared to traditional black charcoal.
-Binchotan is the purest charcoal on earth by the highest carbon proportion (more than 92%) and is completely odorless, and smokeless when burning. White Charcoal is more difficult to ignite than black charcoal; however, it burns hotter and longer.
When hitting the pieces together, it gives a light metallic sound. The white charcoal doesnot break into small pieces while burning.
USAGES
Food grilled over white charcoal retains its natural flavor and moisture because it burns cleanly and without flames. It is popular in high-end restaurants and mostly in Korea and Japan. In addition, binchotan has many uses such as water purification, exhaust filter, deodorant, skin care, metallurgy, used in battery manufacture...
