polyurethane ( abbreviation PU) It is composed of polyisocyanate and polyether polyol or polyester polyol or / And small molecule polyols, polyamines or water and other chain extenders or cross-linking agents and other raw materials. By changing the type and composition of raw materials, the shape and properties of the product can be greatly changed, and the final product can be obtained from soft to hard. Polyurethane products are soft, semi hard and hard Foam plastic Elastomer (polyurethane elastomer is referred to as TPU ）、 paint coating , adhesives, sealants, synthetic leather coating resins, elastic fibers, etc., are widely used in automobile manufacturing, refrigerators, manufacturing, transportation, civil construction, footwear, synthetic leather, fabrics, electromechanical, petrochemical, mining machinery, aviation, health, agriculture and many other fields.

Production mode can be selected for this equipment
Indirect type: module board mode, crushing, granulation and production.
Continuous type: direct injection double shaft extruder, granulation and production.
Thermoplasticity TPU Elastomer is a high molecular weight polymer formed by addition polymerization of polyisocyanate and polypolyol.
Therefore, the metering system and mixing effect must meet certain accuracy requirements in order to produce superior products and achieve stable quality.
Functions and features:
Imported PLC Program control processor, color screen interface, monitor the whole equipment control system.
In case of abnormality, it will automatically judge, diagnose and alarm, and display abnormal factors.
Mixing head: special structure, anti inversion design, uniform mixing, easy maintenance.
Imported metering pump, high precision, good wear resistance, high temperature resistance, accurate metering.
Imported mass flowmeter is used to provide high precision and high repeatability 0.2%
The quality of the mass flowmeter is not affected by pressure, temperature, density, conductivity and viscosity.
The whole pipeline insulation system is controlled by hot kerosene insulation from raw material tank → metering system → mixing head reflux part.
A device for vacuuming and deaeration is provided.
PU Low pressure filling machine
characteristic:
This equipment is a ISO System, two POLYOL System.
This equipment can switch to different colors or different densities of the same product.
The function of one machine is equal to the structure of two machines, which is not limited by the plant and space, and conforms to the economic efficiency of production.
Function:
Mixing head: even mixing, easy maintenance.
metering PUMP: Special metering pump is used for metering, with stable quality.
Raw material mix ratio: wide adjustment range.
Attached twelve Setting timers.
Equipped with temperature, pressure, rotation, filling and cleaning system.
Stirring: the mixing head can fully stir both high viscosity and low viscosity stock solutions.
Device for preventing counter flow of raw liquid: it can be completely sealed.
Application:
Self leather, high rebound, slow rebound, hard foam, car seat cushion, pillow, steering wheel, bumper, bicycle seat cushion, toys, carved door materials, fitness equipment, car filter, cold storage, insulation.
PU Low pressure (four component) filling machine
characteristic:
It is a specially developed model, which can switch different colors and different densities of the same working object in an instant.
Ladbrokes B400 Type, one ISO Department and three POLYOL Systematically combined.
If it is necessary to produce products of multiple colors or densities every day on the same production line due to the space constraints of the plant, choose B400 Type A is more economical, practical and versatile.
The design of the mixing head is relatively light and easy to operate.
The function of one machine is equal to the structure of three machines.
It is not subject to the design of plant space and meets the production conditions.
It is a master control system, which can be selected two － forty Injection time control.
