The formation of the foam for polyurethane foaming machine must have both the blowing agent aqueous solution and air, both of which are indispensable. Next, Hightop Machinery will analyze why the polyurethane foaming machine produces foam indispensable for these two points!
The liquid film surrounding the gas will not form and there will be no bubbles. And without gas, only the foaming agent aqueous solution, bubbles can not be formed. In the bubble formation system, the foaming agent aqueous solution is the dispersion medium, and the gas is dispersed in the liquid to form bubbles, and then numerous bubbles form the foam. The basic principle of the foaming machine is to introduce gas into the foaming agent aqueous solution in a certain way. The change of different models is that the way of introducing the gas is different. According to the way of introducing gas, the foaming machine can be divided into four types: low-speed stirring type, high-speed impeller type, high pressure and medium and low pressure type.
The above briefly describes the necessary conditions for the production of foam by the polyurethane foaming machine. For more information on polyurethane, please continue to pay attention to the polyurethane manufacturer Hightop Machinery.
Polyurethane high-pressure foaming machine is a special equipment for infusion and foaming of polyurethane foam. Polyurethane high-pressure foaming machines are essential in many production areas. Polyurethane high-pressure foaming machine is a kind of precision equipment. In the actual operation pr
High-pressure foaming machine, also known as foam generator, the product of the foaming machine is foam, and what we need in the production process is also foam. In the work, polyurethane foaming has to go through two stages of foaming and curing.The high-pressure foaming machine will present variou
As a common product, high-pressure foaming machine has widely appeared in our real life, and the development trend is increasing:1. Polyurethane products are made of isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retar
The high-pressure foaming machine works for a long time, it is easy to heat up too high, what are the ways to cool down?Today, I will talk to you about the temperature reduction of the high-pressure foaming machine.Large flow box type high pressure foaming machineWhen using a high-pressure foaming m
Because foaming relies on heat, if there is no heat, the foaming agent in the system cannot evaporate and foam plastic cannot be formed. The heat comes from two aspects, one is the heat produced by the chemical reaction, and the other is the heat provided by the environment. The heat of chemical rea
A considerable part of auto parts, especially interior parts, are polyurethane foam products. The polyurethane raw material storage system, polyurethane raw material pre-mixing system, high-pressure foaming machine and molded foaming production line used in the production of polyurethane foamed auto
In order to meet the requirements of epidemic prevention and control, on the afternoon of February 6, Hightop Group held its 2020 annual summary and commendation meeting with the theme of "Gathering Strength and Breaking the Convention" at the headquarters of Hightop Group.

Polyurethane foaming machine is a large-scale equipment, which is used in many production enterprises. The emergence of polyurethane foaming machine production line provides companies with a lot of convenience, and the performance of this equipment is also very good in all aspects. Many people are m
The high-pressure precision foaming machine is carefully designed by the designer according to the user, and there are many models of it. Users can choose the model that suits them according to their needs to purchase. The high-pressure precision foaming machine in the market is economical. It is ve
1. Raw material system. The pressure of the raw material tank should be dry air, and nitrogen should be used as much as possible. Before starting the machine every day, turn the turntable of the raw material filter to the left or right a few times, and remove 200~300ml of raw material from the botto
