Air Conditioner Thermal Insulation NBR&PVC A/C Insulation Rubber Foam Pipe/Sheet Production Line

20-Year Professional Nitrile Rubber Foam AC Sponge Thermal Insulation Pipe Making Machine

Qingdao Huashida Machinery Co., Ltd. is specialized in the production of rubber extruders, air conditioner thermal insulation pipe equipment, rubber-plastic foam insulation pipe equipment.

The screw of Huashta's rubber and plastic foam insulation pipe/sheet production line is divided into feeding section, compression section, throttling section, exhaust section and extrusion section. The throttling section adopts shallow groove equal distance equal depth thread, which can make the rubber material obtain higher shear and stable conveying process, and also improve the exhaust effect. Therefore, the production line has the advantages of fast extrusion speed, high degree of automation, excellent safety performance, advanced technical advantages in modeling, structural performance, vulcanization quality, etc., to ensure the quality of products.

Rubber and Plastic Sponge Insulation Material

This insulation material is made from high-quality nitrile rubber and polyvinyl chloride, combined with premium auxiliary materials and processed through a special foaming technique. It is a soft, energy-saving insulation material that contains no chlorofluorocarbons.

Key Properties:

Soft and Flexible: Bending resistance for various applications.
Temperature Resistance: Effective cold and heat resistance.
Flame Retardant: Enhances safety in use.
Waterproof: Protects against moisture.
Low Thermal Conductivity: Provides excellent insulation.
Shock and Sound Absorption: Reduces noise and vibrations.

These features make it an ideal choice for effective thermal insulation solutions.

The automatic control system has been successfully applied to the rubber and plastic foam insulation pipe production line, and this achievement has further spawned the birth of new rubber and plastic foam foam technology and new process, which is very important to improve the technical level and operation process of rubber and plastic foam insulation pipe production. Once launched, it has brought a huge surprise to the market, and has also attracted the attention of the majority of customers, and the industry has generally reflected well. Rubber extrusion and foaming applied vacuum adsorption process, compared with the previous equipment, the production speed and quality have been greatly improved, its commendable place is to achieve high-speed and stable production. The conveyer belt cutting method can realize multi-tube cutting at a time, neatly retracting, reducing labor and saving production costs. The key is to achieve high-speed production of the pipe at the same time, the foam hole is fine and uniform, the surface is smooth, the texture is soft, and the quality is high. The product not only has a good appearance, but also has the characteristics of low density and light weight, which gives the product a strong market competitiveness.

Application:

Thermal insulation of pipes, vessels and other technological containers in industrial installations.

For cold and hot water supply and heating systems;

Coating of bodies and machine parts to reduce noise and vibration.
