Gypsum plaster retarder how to use
How retarders work on gypsum plaster
Plaster retarder is mainly used for gypsum building materials made of plastered gypsum, bonded gypsum, gypsum putty, gypsum products, etc. It is mainly used to reduce the setting speed of gypsum. At present, there are three main types of retarders: organic acids and their soluble salts, alkaline phosphates, and protein retarders.
The surface of the new phase has a strong active effect on gypsum particles and hydration products. Adsorbed on gypsum particles, the surface retards the gypsum and slurry structure to form a retarder, and often forms an intolerant film on the surface of gypsum particles, which acts as a barrier to the hydration of gypsum particles and hinders the normal hydration of cement. As a result, the hydration rate of gypsum is slowed down and the setting time of gypsum is prolonged.
If you are looking for your nearest gypsum retarder seller.
Then you are likely to search for an e-commerce site like Amazon, or search for your local construction chemical dealer.
Of course, there is no problem buying it through an e-commerce website or a dealer.
But the premise is that you don't use much and don't care about the price.
Why do I say that?
Because if you use a large amount, I still recommend that you buy directly from the manufacturer.
This has three benefits:
First, the price will be very favorable, and there will be no middleman markup.
Second, the quality of the gypsum retarder will be good.
Third, a stable supply guarantee can be obtained.
Building gypsum powder: In the process of decoration and painting, it is necessary to prolong the setting time of gypsum powder. However, the way to slow down the solidification speed of gypsum is to use cold water with a lower temperature when adding water to the gypsum powder. The colder the water, the slower the solidification speed, and the hot water will be faster. If you think this method does not work, you can also add citric acid or mix putty powder in gypsum powder first, mix 108 glue white latex and cellulose in water, and then reconcile.
The amount of gypsum retarder added is determined according to the initial setting time of the gypsum powder itself. If the initial setting time is long, the amount of retarder needs to be added, otherwise, the amount of retarder should be reduced.
The addition amount of gypsum retarder is determined according to the proportion of gypsum powder in gypsum mortar. If the proportion of gypsum powder is large, the amount of retarder needs to be added, otherwise, the amount of retarder should be reduced.
The recommended dosage of this product is 0.5-3‰ of the system, and the dosage needs to be determined by experiment.
Hebei Yida has been engaged in the production of gypsum retarder for 16 years. The gypsum retarder we produce is sold to more than 40 countries around the world.
