Polycarboxylate superplasticizer is used primarily in cement concrete to act as a dispersant. It is composed of polymers containing sulfonic acid group (-SO3H) and carboxyl groups (-COOH) or derivatives of them and features high efficacy, environmental protection, and security.
A new high-performance, slump-retaining polycarboxylate superplasticizer has been developed. It contains isopentenyl and free radical polymerization. This is the Polycarboxylate superplasticizer for high-slump retention type TR-JS28 A high slump retaining polycarboxylate type superplasticizer. This is a new type of polycarboxylic Acid type high-performance hydro reducer. It contains isopentenyl, polyoxyethylene ether, and small monomers through free radical polmerization. These can greatly in
HPEG is most commonly used for the production superplasticizer products of polycarboxylic Acid. HPEG2400 1. Scope of HPEG2400 1. HPEG is most commonly used for the manufacturing of superplasticizer polycarboxylic acid products. 1. Mix the oil directly with water until you get the right amount. The redox initiation condition allows for the production of superplasticizer polycarboxylic acids below 60. The product description for HPEG HPEG 2400 is the new macromonomer of an innovative polycar
Today's concrete superplasticizers These are made from a combination of various materials like polycarboxylate water–reducing mother liquor and/or polycarboxylate shrink-preserving mother liquor. It is the most important role for water-reducing mothers in superplasticizer. Although it is possible that the quantity of the mother solution may change with the changes in concrete, I've never seen water-reducing mothers added to superplasticizer. Perhaps because the sand quality is too high. The a
Polycarboxylate ether superplasticizer, as known as concrete water reducer, is a new generation of polycarboxylate superplasticizer made of polyoxyethylene ether macromonomer, unsaturated acid and sulfonic acid group monomer by radical polymerization. The
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the
Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in ro
The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Touri
A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet com
Concrete is an indispensable raw material in the construction of construction projects. In the process of preparing concrete, in order to improve the performance of concrete, it is necessary to add water reducing agent after adding water, stone, sand
There are no requirements for the site, the high ground is dry, and water and electricity are sufficient. Normal temperature, heating, and normal pressure production processes are all possible.
In modern concrete, the commonly used superplasticizer admixture for concrete mainly include polycarboxylic acid series, naphthalene series, fatty acid series and other water reducers. Different water reducers have their own advantages and disadvanta
White odorless amorphous powder, insoluble in water, soluble in acid. When exposed to the air, it is easy to absorb moisture and carbon dioxide in the air and deteriorate. It is a highly alkaline oxide that can react with carbon dioxide to f
Apple said it will abandon its plan to crack Face ID on independently repaired iPhones.When unauthorized iPhone 13 screen replacements began to cause the Face ID system to malfunction, the often disputed relationship between the company and
What is graphite?Flexible graphite – expanded or exfoliated graphite – is produced from purified natural graphite flakes. In manufacturing, the flakes are mixed with a highly oxidizing acid to produce graphite intercalation compounds. A sudden application of high temperature expands these. The resulting product expanded graphite, is mechanically compressed into shaped products, mainly graphite foil. Although still showing the unique properties of natural graphite, e.g. its excellent conductivity
