How do you make polycarboxylate superplasticizers?

Polycarboxylate superplasticizer is extensively utilized in cement concrete to act as a dispersant. The process of making it can be broken down into the steps below:

synthetic macromonomer

When performing this procedure, it is important to be aware of variables like reaction temperature and the time and quantity of oxidant used to ensure the polymerization process's efficiency as well as the quality of the product.

Post-processing

After the polymerization reaction is complete, post-treatment is needed. The post-treatment process involves dissolving the water and polymer to the ratio specified, adding acidic compounds for neutralization, adjusting the pH that the solution has, and then the addition of a protective colloid as well as other components to produce the final superplasticizer made of polycarboxylate. It is essential to regulate the amount of solution, the pH value, the kind and amount of protective colloid, and other variables to guarantee the quality and effectiveness of the solution.

Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. The cement problem: Some workers in construction will privately add more water for a more fluid concrete. However, this will result in an increase in water-cement, resulting in a hardening of concrete strength that is insufficient, and the cracking phenomenon.

2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in the future. Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation rates of the concrete are accelerated. This results in cracking on the surface. Concrete constructions are most likely to crack in the winter or summer because of the temperature difference.

Add an anticracking agent. A variety of inorganic composite materials can prevent cracking more than 80% foam concrete. Add 2-3 kilograms of anticracking agent per cubic meter.

What is Zinc Sulfide ZnS Product?

Overview of Zinc Sulfide ZnS Powder

Zinc sulfide is an inorganic compound with the chemical formula ZnS. It is a white or yellowish powder that darkens when exposed to sunlight. It is stable in dry air, and will gradually oxidize into zinc sulfate in humid air for a long time. It is usually formed by the action of hydrogen sulfide and zinc salt solution. Zinc sulfide has excellent fluorescence effect and electroluminescence function. In particular, nano-zinc sulfide has a unique photoelectric effect and exhibits many excellent properties in the fields of electricity, magnetism, optics, mechanics, and catalysis.

Physical and chemical properties of zinc sulfide ZnS powder

The chemical bond between Zn and S of zinc sulfide tends to be a covalent bond. The crystal has three different configurations: low temperature type, that is, sphalerite structure, abundant in nature, colorless cubic crystal, Zn, S coordination number is 4, relative density is 4.10. 1020 ℃ High temperature type; high temperature type, namely wurtzite structure, colorless hexagonal crystal, Zn, S coordination number of 4, relative density 3.98, melting point about 1700 ℃. High temperature stable structure of zinc sulfide; high pressure type, namely chloride In the sodium structure, the coordination number of Zn and S is 6, and the relative density is 5.21. There is also a water-based compound, ZnS·H2O, which is a white powder with a relative density of 3.98 and a melting point of 1049 °C. Zinc sulfide is insoluble in water and dilute alkali, insoluble in acetic acid, but soluble in low-concentration strong acids such as hydrochloric acid, releasing hydrogen sulfide. The solubility product of zinc sulfide is similar to the K1·K2 value of hydrosulfuric acid, so the following equilibrium exists in dilute acid:

Zn2+H2S=2H+ZnS

It can be seen that in the strong acid zinc salt solution, the hydrogen sulfide gas cannot obtain zinc sulfide precipitation. Passing hydrogen sulfide gas into the zinc salt solution can get zinc sulfide precipitation, but the precipitation is not complete. Using ammonium sulfide solution as precipitating agent, the zinc ions in the zinc salt solution can be completely precipitated into zinc sulfide. Since the ammonium sulfide solution is alkaline, the acidity of the system can be reduced. In industry, the above method should be used to isolate the air. White zinc sulfide darkens when exposed to light, and is easily oxidized to zinc sulfate in the air. Zinc sulfide can be used alone as a white paint pigment or in combination with zinc oxide. Pure zinc sulfide does not emit light. If a trace amount of manganese, copper, and silver are added to the zinc sulfide crystal as an activator, it can emit different colors of fluorescence after being illuminated, called phosphor powder, which is used to make fluorescent screens and luminous paints. Zinc sulfide is also used in leather, enamel, rubber, dye and other industries.

Zinc sulfide is corrosive and toxic. It can irritate the skin. Operators should wear work clothes and protective equipment. The workshop should be well ventilated.

Application of Zinc Sulfide ZnS Powder

1. It can be used as analytical reagent, phosphor matrix, photoconductor material; or used in the manufacture of dyes, coatings, pigments, glass, curing oil, etc.

2. Zinc sulfide is widely used in the production of infrared windows, fairings, and infrared optical components. It has the characteristics of high purity, insoluble in water, moderate density and easy processing. Zinc sulfide has good refractive index uniformity and consistency. It has good image transmission performance in the 8-12μm band, but some parts start to absorb after 10um. In the mid-infrared, transmission is higher, and absorption and scattering increase with shortening of wavelength. Zinc sulfide is highly resistant to harsh environments, with twice the hardness and breaking strength of zinc selenide.

Robust front optics for zinc sulfide thermal imaging systems in the infrared window and thermal band (8 to 14 μm).

Single crystal zinc sulfide is available, but not common. In the usual spectral range, the scattering is very low. It can be used as a high-power laser device under the condition that the bulk absorption and internal structural defects of the material are strictly controlled, and the polishing technology with minimal damage and the coating technology with the highest optical quality are used.

Zinc sulfide oxidizes significantly at 300 ℃, plastic deformation occurs at about 500 ℃, and dissociation occurs at about 700 ℃. For safety reasons, zinc sulfide windows should not be used in normal environments above 250°C.

3. For optical coating targets, X-ray screens, luminous dials with trace amounts of radium or neodymium salts added, TV screens, and paint pigments.
