Precautions when polyetheramine is used in construction

Containers for amino-terminated polyethers can be made of steel, aluminum, polyethylene or polypropylene. The storage temperature should not exceed 70°C. To prevent moisture absorption and oxidation, it is recommended that the container be filled with nitrogen. We generally pack them in clean, dry, sealed, leak-free galvanized iron drums. Avoid sunlight, rain and fire sources during storage. Not subject to storage regulations for flammable liquids, but should avoid entry into ground or surface water as it is not readily biodegradable.

Generally, the toxicity of amino-terminated polyethers when ingested into the mouth or in contact with the skin, eyes, and mucous membranes is negligible, so personal protective measures are not required during use. However, because the alkalinity can irritate the skin and eyes, protective equipment such as safety glasses and gloves should be worn during operation.

When polyetheramine 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 understand Next, what are its construction techniques?

A. Grinding: When grinding the new terrazzo floor to a medium-sized grinding disc, you can clean up the remaining slurry and water on the surface; let the ground dry naturally for use.

B. The chemical penetration reaction of polyetheramine: brush the crystal surface agent material on the dry terrazzo surface, and quickly use the polishing black pad of the crystal surface refurbishment machine to polish it back and forth repeatedly until the surface is rubbed and heated and dry.

C. Repeat one more time of potion: After the last polishing and drying for more than 2 hours, you can use the black pad on the crystal face refurbishment machine to put the material and rub it dry and polish it; until the surface is dry and the crystal is polished to a bright effect.

D. Maintenance and use of polyetheramine: It can be put into use immediately after construction, but it still needs to be dried and maintained for 24 hours before it can be mopped on wet ground. Daily use should avoid or reduce the probability of sharp objects in contact with the ground.
