Polyurethane cold storage insulation precautions

Polyurethane rigid foam in the state before molding is two kinds of liquid, in the molding of these two kinds of liquid mixing, through the polyurethane spraying machine to become a solid raw material, so the construction molding method is more mobile. As long as it is not crushed polyurethane rigid foam since the skin layer of the case, the construction period requirements are not harsh, which is also very good exterior wall insulation construction system, just in the field construction of the gunner's technical requirements, but because of the shortage of skilled workers, will give the large limitations of the promotion of the application of the obstacles, it must be declared here is the polyurethane spraying machine products of the benefits of the product is: no seams as well as the overall performance of a good, for flat roofs For flat roofs, the function of heat preservation and waterproofing is superior to that of polyurethane sheets.

The production efficiency of polyurethane spraying materials is relatively high, especially for large areas or for the treatment of the whole object, the molding speed is relatively fast, the production efficiency is also very high, the ability to paste is particularly strong, can be firmly pasted in many different places and on different surfaces, and their coefficient of thermal conductivity is also very important.

The performance of polyurethane spraying material is also relatively stable, and acid and alkali will not have any chemical reaction. Is a kind of aging resistance, low temperature resistance, corrosion resistance, fatigue resistance, superior performance, at the same time in the process of using with cement or metal, glass building materials, also has a very strong adhesion, with the ability to play to shorten the cycle of the characteristics of the work.

Cold storage insulation construction what need to pay attention to safety matters:

1, the first to figure out the policy production line skills details: foaming machine type, filling flow, filling before the temperature control value, kang road insulation temperature control value and thermal insulation moment, box body filling mouth in which and foam material flow through the road trip, filling after closing the mold sealing hole operation process.

2, to the site operator, quality inspector for inquiry at the time of the current skills, materials, what are the shortcomings and please ask them to put forward what other detailed needs.

3, a, b two kinds of materials are iron barrel packaging, flammable, toxic, storage should be tightly closed, placed in a cool, dry, no strong direct sunlight places.

4、Construction temperature should be above 5℃.

5、If the material is found to have the phenomenon of deposition, it should be mixed evenly and then used to avoid affecting the quality.

6, the construction should pay attention to fire prevention, in those construction personnel should adopt protective methods, in those construction sites need to be ventilated outstanding, in order to prevent solvent poisoning.

7, the temperature and humidity of the environment at that time (work) changes.
