Reduce water into the concrete mix to reduce the water content in the mix while preserving the softness of the concrete.
Most of them are anionic surfactants such as lignosulfonate, polymer, formaldehyde, naphthalene, sulfonate, etc.
The addition of concrete will affect the cement particles. This will increase processing capacity.
Reduce water consumption in equipment and increase flowability, mix concrete or reduce cement consumption and save special cement Additives significantly reduce the content of the mixture under the same basic condition as concrete.
Damaged cardboard is called supersoft. The admixtures reduce water consumption by at least 15% when the amount of polycarboxylate concrete poured is significantly equal.
Its form is divided into polycarboxylate concrete water and powder.
Water formulations contain 20%, 40% (also known as alcohol) and 60% solids, while powders typically contain 98% solids, depending on the reducing agent’s ability to reduce and improve water.
It is divided into common dehydrating agents.
(referred to as plasticizers Water reduction ratio greater than 8% based on lignosulfonate) High efficiency polycarboxylate concrete
(also known as superplasticizer) Plasticizer Water reducing content 14% or more nephtha Fat, base melamine, sulfate, fatty, etc.
And high performance water reducing agent.
(including aqueous reducing agents containing 25% or more aqueous reducing agents with polycarboxylic acid), initial strength, standard class and slow class.
Depending on the composite material, it is divided into:
Naphthalene plasticizers, aliphatic plasticizers, amine plasticizers, polycarboxylate plasticizers, etc.
Lignosulfonate superplasticizer, naphthalene superplasticizer, melamine superplasticizer, sulfate superplasticizer, acidic superplasticizer, wetting agent, Polycarboxylate superplasticizer.
Superplasticizers have a high diffusive effect on the cement and can increase the fluidity of the cement mixture and cause the polycarboxylate concrete to fall.
While reducing water consumption and improving the durability of concrete. and can cause excessive bleeding.
In principle, superplasticizers do not change the service life of concrete. When the dosage is high (overdose), there is a slight delay in the setting process.
But it will not slow down the initial strength of the hardened concrete.
It can polycarboxylate concrete consumption and increase the strength of concrete for all ages.
By maintaining constant resistance It can contain more than 10% cement, very low chloride ion content and does not corrode steel bars.
It can improve the waterproofing, defrosting and corrosion properties of concrete. and improve the durability of concrete.
How it works after polymerization.
This method consists of first forming the main chain and then adding the side chains.
The problem with this method is that the compatibility between polycarboxylic acids and polyester is very poor.
Water is generated during esterification. Phase separation occurs and esterification activity is difficult.
Therefore, the selection of polymers compatible with polycarboxylic acids is central to the synthesis.
Integration and polymerization in place. In this method, the subsequences are introduced at the same time as the main strand is polymerized.
As a reaction medium for monounsaturated carboxylic acids.
Polyether overcomes the problem of poor compatibility between polycarboxylic acid and polyether.
Chain transfer agent and initiator are added dropwise to the aqueous solution.
About the waxing process of candle machine
1. Follow wax: Add some water to the pot, put the solid paraffin into the pot (can melt the paraffin into wax water), melt it into liquid wax water until the pot is added to the configuration pigment color.
Soy Wax is a vegan wax made from the complete oiling of soybeans. Like honey, it is considered a natural wax, and 100% pure soy wax is often used in containers of soy wax.
Paraffin wax is a hydrocarbon mixture extracted from some distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and it is a white or light yellow translucent solid.
Paraffin is a purified mixture of solid saturated hydrocarbons. Paraffin wax is a flaky or needle-like crystal obtained from lubricating oil fractions obtained by distillation of crude oil through solvent refining, wax freezing crystallization, and press dewaxing to obtain wax paste, and then solvent deoiling and hydrofining.
With the increasing popularity of scented candles, and the diversification of various candles, events need to be held, the atmosphere needs and incense. The demand for raw materials to make candles is also increasing.
refined paraffin wax candle: advantages, disadvantages and differences of other wax candle
Today, you can find all kinds of candles in sales – home furnishing, decoration, seasoning. You can select any shape and color. The composition of the product is also different.
