The construction process of polyether amine is very simple, as long as you master its operation steps, and then further improve it on this basis. The above introduction is expected to be helpful for your future use.

Containers for amino terminated polyethers can be made of steel, aluminum, polyethylene or polypropylene. The storage temperature should not exceed 70 ℃. In order to prevent moisture absorption and oxidation, it is recommended to fill the container with nitrogen. We usually use clean, dry, sealed and leak free galvanized iron drums for packaging. Keep away from sun, rain and fire during storage. It is not subject to the storage rules for flammable liquids, but it should be avoided to enter groundwater or surface water, because it is not easy to be biodegradable.

Generally, the toxicity of amino terminated polyether in oral cavity or in contact with skin, eyes and mucous membrane can be ignored, so there is no need for personal protection measures in use. However, because its alkalescence will irritate the skin and eyes, wear safety glasses, gloves and other protective equipment during operation.

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

A. Grinding: when grinding the new terrazzo floor to medium mesh grinding discs, the residual slurry and water on the surface can be cleaned; And let the ground naturally cool and dry for use.

B. Penetrant reaction of polyether amine coating agent: paint a layer of crystal face agent material on the dry terrazzo surface, and quickly use the crystal face refurbishing machine to install the polishing black pad to repeatedly polish until the surface is rubbed, heated and dry.

C. Repeat the last dose: after the last dose is polished and dried for more than 2 hours, the crystal face refurbishing machine can be used to install the black pad, place the material, and polish, dry and polish; Until the surface is dried and the crystal is polished to a bright effect.

D. Curing and putting into use of polyether amine: it can be put into use immediately after construction, but it still needs to be dried for 24 hours before the wetland can be used for mopping. The probability of contact and friction between sharp objects and the ground shall be avoided or reduced in daily use.
