What is the role and mechanism of water

We often see concrete used on construction sites and in home improvement. However, you may not know that adding a water-reducing agent to concrete is a very important step. So, why do we need to add a water-reducing agent to concrete, and what is the function and mechanism of this additive? Next, we will reveal the answers for you.

First of all, let us understand what is water water-reducing agent.

Water reducing agent is a chemical additive, and the main component is a surfactant. It can greatly reduce the amount of water required for concrete, thus improving the strength and durability of concrete. Using this additive can save the amount of cement, reduce the cost of concrete, and improve the quality of construction.

So, what's the purpose and function of the water-reducing agents?

Particularly, they include the following elements:

1. The effect of surfactants on water is reducing The surfactant that is contained in this water reducing ingredient may be applied to the surface of cement particles, causing them to become more dispersed, thereby reducing the demand for water in the concrete.

2. Dispersing effect Water-reducing agents will make the water within the concrete spread more uniformly, which can prevent the possibility of drying locally and settling.

3. Reduced water-water absorption: These agents reduce the amount of pores present in concrete, thereby improving its permeability and endurance.

The development history of water-reducing agents:

1. The first generation of water-reducing agent

Ordinary water reducing agent (water reduction rate 8%), also known as plasticizer; the main representative of the lignosulfonate system (sodium lignosulfonate, calcium lignosulfonate, magnesium lignosulfonate, etc.).

2. The second generation of water-reducing agent

High-efficiency water-reducing agent (water reduction rate 14%), also known as superplasticizer; the main representative of the naphthalene system, melamine system, amino sulfonate system, and aliphatic system.

3 .Third generation water reducing agent

High-performance water-reducing agent (water reduction rate 25%); the main representative of polycarboxylic acid water-reducing agent, which can be divided into early-strength type, standard type, and slow-setting type.

In short water-reducing agent play an important role in concrete. It will not only increase the durability and strength of concrete, but also reduce concrete needed and cut costs. This is why water-reducing agents are an essential chemical ingredient in construction.

Boron's energy gap of 1,50 to 1,556eV is greater than that of silicon or germanium. It transmits parts of infrared. At room temperature, boron is not as good a conductor of electricity. Boron is available in crystalline boron or amorphous form. Boron is odorless and tasteless. Amorphous Boron is a brownish powder. Crystalline boron, on the other hand, is black in color and is extremely hard. (roughly 9.5 Mohs' Scale) It is also a poor conductor when at room temperatures. boron lies between the non-metal and metal series in the periodic table. Boron's chemical properties are active due to many of its characteristics. These include a strong electronegative charge, low atomic size, and a centralized nuclear charging. Similarly, boron's non-metal property is that of silicon. At high temperature, boron may react with sulfur, oxygen, nitrogen or halogen. Boron remains stable at room temperature. However, it becomes oxidized and then burns when heated up to 300°C. Boron is easily combined with many different metals in order to produce metal boride. High purity boron can be crystalline. The boron trichloride and tribromide can be reduced to crystalline boron by heating filaments with hydrogen in the vapor phase.

Micro-porous PVC-SiO2 Separator for Gelled Lead-acid Battery

PVC and SiO2 Separators PVC separators that are made by wet processing are mostly used in lead-acid sealed gel batteries. PVC-SiO2 Separators have higher porosity and more uniform pore sizes than sintered PVC Separators, as well as better puncture and compressive resistance, greater toughness and better compression strength than glass fibre separators. It has better chemical stability and oxidation resistance than polyethylene PE.

PVC and SiO2 Separator Properties:

1. The PVC/SiO2 separator is characterized by high porosity, a small maximum pore, and high liquid absorption. These characteristics allow the separator to retain the electrolyte easily, and have a rapid penetration rate.
2. The wet elastic is strong and can provide electrolyte to the plate while keeping the ion conductivity unblocked.

3. The "acid-strategization" phenomenon can be effectively prevented by a battery with strong liquid transfer abilities.

4. Based on the glass fiber. By adding organic fibers, the PVC/SiO2 separation is enhanced in terms of tensile strength and other performance indicators.

Application of the PVC-SiO2 separation in batteries:

1. The positive and the negative plates are placed close to each other, but should not be in direct contact. A separator between the plates is used. The PVC-SiO2 should be porous to allow electrolyte into the separator, and have good acid resistance and alkali tolerance. Wood, microporous Rubber, Microporous Plastic, and Resin-impregnated Paper are all good materials for separation.

2. The battery separator is responsible for carrying the electrolyte containing sulfuric acid in the cell. In the lean state, the separator shares the entire amount of sulfuric acid needed to meet the rated battery capacity with the electrode plate. For this to work, the separator needs to be large enough to absorb the sulfuric acids. Also, the battery must have enough space to accommodate the separator.

3. The PVC-SiO2 separation should provide sufficient oxygen channels to allow the oxygen that precipitates from the positive plate to pass through it to the negative, where it can be converted into oxygen. cycle. The separator must have a reasonably microporous surface, and the acid saturation of the separator must be determined at the time the battery is being designed.

4. The separator is used in lead-acid batteries with valve regulation to prevent the active material from falling off of the electrode plates and to keep the electrode plates from deforming. This prolongs the service life. It is necessary that the separator shrinks after being injected with sulfuric acid.

5. The internal resistance of a battery includes the resistance of a battery separator as well as the resistance that is formed when the separator contacts the plate. It is necessary that the separator has a low resistance and also be put under greater pressure when designing the battery. So, the PVC/SiO2 separation is in contact with the poleplate, and resistance is reduced at this point.

The Characteristics and Application of Quartz Powder

What exactly is quartz powder? It's also called silicon fine powder. Quartz powder is a hard mineral that is known for its chemical stability and hardness. The quartz sand color is white or translucent. It has a hardness of 7, it's brittle and hard with shell-shaped fractures, a glossy oil finish, a chemistry that shows obvious heterogeneity. The product of the quartz mine is referred to by the term below 120 mesh. Quartz powder has more than 120 different products as their destination.
What are the uses of quartz powder?
Quartz is one the most important minerals on the surface of the Earth. Quartz Powder has many uses in industry.

Rich quartz sand used in glass making. Quartz sand plays a key role in the production of instrumentation, flat-sheet, specialty, and fiberglass glass. Quartz can also be used to produce lenses for optical instruments such as telescopes and microscopes. It is also used in prisms, sensors and electronic and scientific instruments.

Quartz Powder as an Abrasive. Because of its high hardness, which is seven on the Mohs scaling, quartz powder is more durable and effective than many other natural substances. Quartz powders and finely ground oxides have many uses, including sandblasting media, scouring cleanser, grinding media, grit, and sanding for sawing and sanding.

Quartz Powder used in the Slab Industry. Quartz Grains and powder are also used to produce artificial marble slabs. Since the very beginning, we are producing the highest-quality products for this industry.

Other Uses for Quartz Powder: You can use quartz powder as a filler when making rubber, putty, or paint. The sized and screened quartz grains can be used for roofing granules or as filter media. Quartz Powder is used to provide traction in the railroad and mining industry. These sands can be found on beaches, golf course sandboxes and volleyball courts.

Quantum Powder for Investigation of the Properties of Engineered Cementitious Composites Reinforced by Fibers
ECC mixes are more workable when they contain quartz powder and silica dust. These materials can absorb water. Water absorption is lower for cement and quartz than silica. Silica fume, however, has a specific area of between 15,000-30,000m2/kg. The use of water is constant in all ECC mixtures. In essence, these conditions may be the cause of the poor workability of ECC mixes. However, by adjusting superplasticizer content (SP) for each mix, a good consistency and working ability of ECC mixes can be achieved.

In the case of PVA fiber-based ECCs, adding quartz powder can improve the average compressive force of 6.85% or average strength ratio of 1,0685 compared to PVA fiber-based samples with no quartz powder. The addition of quartz to steel fibers based ECC can improve the average compressive strengths of 8.09% and the average strength ratios of 1.0809, compared with the steel fibres based ECC samples that do not contain quartz powder. The addition of the quartz powder to the steel fibers and PVA ECC samples led to higher compressive strengths with an average strength of 1.0747 when compared to samples of FR ECC without quartz.
