1. The drying time of plastering mortar on the wall The drying time on the wall is mainly related to four aspects: the degree of water absorption of the wall, the water retention of the mortar, the setting time of the mortar, and the ambient humidity. 1. The wall humidity is normal and the air
In the actual application process of the external walls internal insulation system. There are also some shortcomings that are widely criticized by everyone. For example: condensation (condensed water on the inner surface), mildew problems. Almost as soon as internal insulation is mentioned, everyone subconsciously thinks of the above two keywords. But is this problem really
Redispersible polymer powder(RDP) is a water-soluble redispersible powder, which is a polymer of butadiene and vinyl acetate, and uses acrylic emulsion as a maintenance colloid solution. Therefore, RDP is very popular in the construction industry sales market, and the inappropriate use of RDP leads to unsatisfactory actual effects of engineering construction. The use of suitable
Hydroxypropyl methyl cellulose for construction needs to avoid the infiltration of water into the wall, and the appropriate amount of water is retained in the mortar, which can make the cement fully produce good performance and perform the effect of water and water. Hydroxypropyl methyl cellulose The viscosity of the base cellulose in the mortar
When using Sodium Carboxymethyl Cellulose in the food production process. It is necessary to dissolve the CMC first. There are two usual methods— 1. Mix CMC with water directly to prepare a paste-like glue. Then use it for later use. When configuring Sodium Carboxymethyl Cellulose paste, first add a certain amount of clean water to
For a long time, the reactive dye printing paste is mainly sodium alginate. With the rising price of sodium alginate and some defects exposed in the process of rotary screen and flat screen printing. Some other natural polysaccharide pastes or synthetic pastes have emerged as alternatives to sodium alginate. This article mainly compares sodium carboxymethyl
What is the ash content of hydroxypropyl methylcellulose? Ash, also known as scorch residue, is simply understood to be the impurities contained in the product. It occurs naturally during the production process. After the product has come out of the etherification reactor, it enters the neutralisation kettle, where the pH value is first adjusted to
Causes and solutions of blistering putty(1) 2. Solutions for blistered putty 1. For large blistered putty surfaces, use a spatula to directly crush the small bubbles and re-scrape the blistered surface with a suitable putty. 2. For particularly rough walls, generally choose a coarse putty for the base material if possible. 3. Clean up the
Putty is the basic material for wall decoration and is mainly used to level the wall surface so that the paint can show its perfect decorative effect. However, the process of puttingty construction can lead to phenomena such as blistering of the putty layer if the details are not handled properly. This causes uneven application
Many people may not understand why putty powder is used for decoration. Putty powder is simple to use and can be used by simply adding water and mixing. It is mainly used to treat the wall when painting to make it smooth for the paint job. Not only is putty powder simple to use and
