1. Overview:

This equipment mainly uses TDI and MDI as chain extenders for the casting type polyurethane flexible foam process casting machine.

2. Features

①High-precision (error 3.5~5‰) and high-speed air pump are used to ensure the accuracy and stability of the material metering system.

②The raw material tank is insulated by electric heating to ensure the stability of the material temperature.

③The mixing device adopts a special sealing device (independent research and development), so that the stirring shaft running at high speed does not pour material and does not channel material.

⑤ The mixing device has a spiral structure, and the unilateral mechanism gap is 1mm, which greatly improves the product quality and the equipment stability.

3. Uses:

Mainly used in the production of polyurethane flexible foam products with TDI and MDI as chain extenders. Such as car seat cushions, memory pillows, steering wheels, mattress sofas, etc.

The equipment is composed of raw material tank, metering pump, material pipe and mixing device to form an open-loop flow control system. The raw materials in the tank are automatically metered by a high-precision aviation pump (adjusted by an energy-saving frequency conversion motor), and then enter the pouring head through the raw material pipeline; when pouring, the head motor automatically starts the mixing head, so that the raw materials are uniformly mixed at a high speed in the mixing bin; , the head programmer automatically closes the injection valve and switches to the backflow state. Adjusting the speed of the variable frequency motor can change the flow rate of the raw material output, thereby controlling the size and ratio of the raw material flow. The machine head is suspended by a spring steel 7-shaped boom, which can be freely rotated 180°, and the upper and lower heights can be flexibly adjusted.
