Polyurethane high pressure foaming machine is a special equipment for pouring foaming of polyurethane foam. 

As long as the performance index of polyurethane component raw material (isocyanate component and polyether polyol component) meets the formula requirements. 

Through this equipment, we can produce uniform and qualified foam products. 

It is prepared by chemical reaction foaming with polyether polyol and polyisocyanate in the presence of foaming agent, catalyst, emulsifier and other chemical additives. 

Polyurethane high pressure foaming machine can be used for automobile interior decoration, thermal insulation wall spraying, thermal insulation pipe manufacturing, bicycle and motorcycle seat sponge processing. 

How to buy imported polyurethane foaming machine? 

1. Fully understand the type of foaming machine: the basic principle of polyurethane foaming machine is to introduce gas into the aqueous solution of foaming agent, but different types of foaming machines introduce gas in different ways. 

For example, the low speed stirring type is based on the slow rotating blade to introduce gas, the bubble yield is small, the foaming efficiency is low. 

The high-speed impeller is driven by the high-speed rotating impeller, the bubble diameter can not be controlled, and the foam is uneven. 

The bubble formation rate of high pressure and medium and low pressure is fast, and the bubble with high efficiency is uniform and fine. 

2. Understand the basic parameters of polyurethane foaming machine: 

A. Production: production is the bubble volume, must be slightly higher than their own bubble volume 20%, to leave room for bubble production should be the following limit for the approved calculation and not the upper limit. 

B. Installed capacity of polyurethane foaming machine: installed capacity is the total installed power, which is of great significance to calculate the adaptability of electrical circuits to total electricity consumption. 

C, polyurethane foaming machine size and foam diameter range. 

Polyurethane foaming machine. 

The price of polyurethane high pressure foaming machine is more expensive than that of low pressure foaming machine, and it also has perfect precision number in manufacture. The precision number of low pressure foaming machine is lower, and the mixing efficiency of high pressure foaming machine is better than that of low pressure foaming machine. 

Foam cell structure is stable and uniform, good insulation performance and other aspects of the perfect system. 

The high pressure foaming machine is easy to manage and start, and the surroundings are always clean. 

Polyurethane foaming agent is environmentally friendly, has no peculiar smell, does not cause pollution to the environment, and brings good quality to life. The performance of high-pressure foaming machine is also very durable. The intelligent operation of high-pressure foaming machine is used in automatic production line. 

The above advantages, it can be proved that the low-pressure foaming machine and high-pressure foaming machine is still very different. 

Polyurethane high-pressure foaming machine in the production process often appear some small problems, which requires users to often carry on the maintenance and maintenance, below we take a look at the high-pressure foaming machine common problems and solutions. 

1. The black material tank is not heated, so it is necessary to thoroughly clean the liquid level and the black material pump filter screen in the black material tank. 

2. The water cooler does not cool down, so it is necessary to thoroughly clean the dust cover inside. 

3. When mixing with high voltage, the mixing pressure is too small. The setting of pressure setting time in electrical control cabinet F10 should be 3 seconds, and the setting of holding pressure time should be 3 seconds. 

4. The piston of the high pressure mixing head is stuck, the oil pressure is too low, adjust the upper and lower limit of the oil pressure, thoroughly clean the piston and replace the hydraulic oil after production.
