When polyether amine curing agent is used in construction, we need to further understand its construction technology. Only in this way can we avoid the harm caused by wrong construction methods. So, today, Xiaobian will take you to understand, what is its construction technology?

A. Grinding: When the new terrazzo surface is ground to the medium number of grinding discs, it can clean up the remaining slurry water on the surface, and let the ground dry naturally.

B. Penetration reaction of polyether amine: brush the crystal surfactant material once on the dry terrazzo surface, and polish the black pad back and forth with the crystal surface retreading machine until the surface rubs hot and rubs dry.

C. Repeat the reagent more than once: after the last polishing and drying for more than 2 hours, it can be polished and polished with the black pad on the surface of the crystal retreading machine, until the surface is polished and the crystallization has a bright effect.

D. Maintenance and put into use of polyether amine: It can be put into use immediately after construction, but it still needs 24 hours of dry maintenance before wetland can be used to mop the ground. Daily use should avoid or reduce the probability of contact and friction between sharp objects and the ground.

Polyether amine is obtained by ammoniation of polyethylene glycol, polypropylene glycol or ethylene glycol/propylene glycol copolymer at high temperature and pressure. By choosing different polyalkyl oxide structures, a series of properties such as reactivity, toughness, viscosity and hydrophilicity can be adjusted. Amino groups provide the possibility of reacting with a variety of compounds. 。 Therefore, when we use it, we will use it reasonably according to its excellent properties. Correspondingly, its advantages in some aspects will be more advantageous than similar products, which is why more and more people like to use it as curing agent.

Polyether amines contain special molecular structures, which give them excellent comprehensive properties. At present, the types of polyether amines include a series of products with single, double and triple functions. It has been widely used in many fields, such as polyurea spraying, large-scale composite materials and epoxy resin curing agent. Through the above understanding, we believe that you have a more in-depth understanding of it, and how we use it depends on the specific analysis.
