S&L's Role in Crafting Heating Pads: From Mixing to Market

Unveiling the Heating Pad

What exactly is a "Heating Pad"? As its name suggests, it serves as a heating tool, often also referred to as a warm sticker. The raw material layer of a heating pad has a remarkable property. Once exposed to oxygen, it can continuously emit heat for a span of 12 to 20 hours. The underlying mechanism involves the conversion of chemical energy into heat energy, which is the fundamental working principle. To ensure that the heat persists for an extended period, mineral vermiculite is employed as an insulating material.

How does a Heating Pad work?

When you examine the components of a heating pad, you'll find dark brown solids, which include toner, NaCl solids, Fe₂O₃ solids, and magnesium-aluminum salts. Given that no reaction should occur before the heating pad is put to use, its packaging design is quite unique. It consists of a raw material layer, a gelatin layer, and a non-woven fabric bag.

The non-woven fabric bag is crafted from a micro-porous breathable film, and it is encased in a conventional airtight bag. To activate the heating pad, one simply removes the outer package, exposing the non-woven bag to the air. This allows oxygen to penetrate through the permeable film.

The release duration and temperature of the heat are regulated by the oxygen permeability rate of the permeable film. This precise control ensures a consistent and reliable heating experience.

A Prominent Heating Pad Manufacturer: KobaXXXXX Pharmaceutical Co. LTD

KobaXXXXX Pharmaceutical Co., LTD. is an esteemed company with a rich history spanning over 130 years. It is primarily engaged in the research, development, production, and sales of a diverse range of products, including drugs, medical devices, daily necessities, and food. In 1998, the company established its first production base in China. This base mainly supplies products such as heating pads, ice stickers, and aromatic agents.

Our Long-Standing Partnership with KobaXXXXX

Our association with KobaXXXXX dates back to 2006. In that year, S&L received its first purchase order from KobaXXXXX, which was a 4000L double-screw conical mixer (DSH-4). Subsequently, S&L went on to supply three more mixers of the same specification to their factories in Japan and the USA.

The conical screw mixer DSH plays a crucial role in the production of heating pads. It is mainly utilized for mixing solid raw materials like iron oxide and vermiculite. Additionally, it is used to spray liquid additives during the mixing process, and the final mixture serves as the raw material for heating pads.

In 2021, with the aim of expanding production, KobaXXXXX planned to add a new mixing machine to its Hefei plant. This move not only boosted their production capacity but also solidified their leading position in the Chinese market.

Features of the Equipment

Material Compatibility: All parts that contact with the raw materials are made of high-grade stainless steel, such as SUS316L. This ensures the durability and hygiene of the mixing process.

Speed Control: A Variable Frequency Drive (VFD) control is essential for regulating the rotation speed of the mixer, allowing for precise control over the mixing process.

Feeding and Discharging: Typically, the mixer features manual feeding and pneumatic discharging, which provides convenience and efficiency in the operation.

Liquid Spraying System: A liquid spraying system is also a necessary component, enabling the even distribution of liquid additives during the mixing.

The Working Principle of the Mixer

The conical mixer (DSH) is composed of a conical vessel, two internal screw agitators, and the driving parts. The agitators, while rotating on their own axes (rotation), also perform a planetary motion (revolution) along the inner wall of the conical vessel. This is achieved through the rotation of the screw arm around the center of the container.

Through the rotation of the screws, the equipment repeatedly lifts the material, creating shear, convection, and diffusion movements within the vessel. These actions ultimately lead to the achievement of uniform mixing of the materials.

Advantages of the Mixer

Versatile Applications: The mixer can be used in a wide variety of applications, making it a flexible choice for different production needs.

Large Capacity: With its large volume, it can handle substantial amounts of materials, increasing production efficiency.

Minimal Temperature Rise: The design of the mixer minimizes the temperature rise of the materials during the mixing process, preserving the integrity of the ingredients.

Complete Discharging: It ensures complete discharging of the mixed materials, reducing waste and improving productivity.

Energy-Efficient: The mixer is designed to be energy-efficient, helping to reduce operational costs.

In conclusion, our partnership with KobaXXXXX in the production of heating pads has been a successful one, thanks to the quality and functionality of our S&L mixers.
