摘要： PURPOSE: A urethane foaming device for both high and low temperatures is provided to enhance the flame retardancy and compressive strength of a urethane foam by adding gas and functional powders for raw materials into the urethane foam. CONSTITUTION: A urethane foaming device for both high and low temperatures comprises a high-pressure foaming head and a low-pressure foaming head(9). The high and low pressure foaming head are respectively formed in one side and the other side. A crude liquid passage(13) connects the two heads. Crude liquids firstly mixed in the high pressure foaming head are transmitted to the low pressure foaming head through the crude liquid passage. The low pressure foaming head comprises an inlet port of powdered raw materials and an injecting port of foaming gases. The powdered raw materials and the foaming gases are added and mixed again in addition.

摘要： An environmentally friendly PU foaming apparatus and a method thereof according to the present invention comprise a raw material insertion step, an emulsification stage and a foaming step. The present invention lowers the specific gravity of a hydroxide containing OH by causing an emulsification reaction on the hydroxide containing OH by mixing the hydroxide containing OH with harmless gas, forms a mixture by mixing the hydroxide containing OH and an isocyanate polymer containing NCO under ambient pressure environment and forms a PU foam by allowing foaming action to be caused in the mixture when the harmless gas is escaped from the mixture. Accordingly, the present invention is able to accomplish environmental protection effects since PU foaming is able to be directly performed without using HCFC and water and is able to guarantee the quality of PU foam by preventing hydrolysis reaction from being caused.
