polycarboxylic acid superplasticizer is a concrete admixture that can reduce the consumption of water for mixing without essentially changing the concrete slump.
Most of them are anionic surfactants such as lignosulfonate, naphthalenesulfonate formaldehyde polymer.
After adding the concrete mixture, it can disperse cement particles, which can improve its workability, reduce unit water consumption, and improve the fluidity of the concrete mixture.
Or reduce unit cement consumption and save cement.
Appearance morphology is divided into liquid and powder. The solid content of water is generally 20%, 40% (also known as mother liquor), 60%, and the solid content of powder is generally 98%.
Depending on the polycarboxylic acid superplasticizer / enhancing capacity of the water-reducing agent.
It is divided into a normal polycarboxylic acid superplasticizer (also called a plasticizer and a water-reducing rate typified by lignosulfonate of 8% or more) and a high-performance water-reducing agent (also called a high-performance water-reducing agent).
Will be. , Naphthalene, melamine, sulfamate, aliphatic, etc. are represented by a water reduction rate of 14% or more, and a high-performance water reduction agent (water reduction rate of 25% or more, including polycarboxylic acid).
It can be divided into water reducing agent), early strength type, standard type, and retard type.
It can be divided as follows according to the constituent materials.
Polycarboxylate High Performance Water Reducer is a high performance water reducer for concrete with the world’s most advanced technology, highest technology content, best application prospects, and best overall performance.
polycarboxylic acid superplasticizer are a composite product of carboxylic acid grafted multi-element copolymers and other effective additives.
Performance comparisons with similar products at home and abroad show that polycarboxylic acid superplasticizer have reached the current internationally advanced level in terms of technical performance indicators and cost performance.
There are also some problems with polycarboxylate high performance water reducing agents:
Polycarboxylate high performance reducing agents are suitable for prefabricated and cast-in-place concrete, reinforced concrete, and prestressed concrete in the construction of high-speed rail, passenger lines, industrial and private buildings, roads, bridges, ports, airports, etc.
Especially suitable for projects with long construction periods and high demand for concrete slumps, such as nuclear power plants.

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.
