- Allyl Polyoxyethylene Ether (APEG)：It is non - toxic and has good water solubility, and will not deteriorate by hydrolysis. It is a main raw material for synthesizing polycarboxylic acid - based cement water - reducing agents, and can react with double - bond - containing substances such as acrylic acid to synthesize high - performance water - reducing agents. For example, APEG1200 is a white to slightly yellow solid, and APEG2400 is in the form of white to slightly yellow flakes.
- Methylallyl Ether (HPEG)：It is non - toxic, non - irritating, and has good water solubility, without hydrolysis deterioration. It is the most widely used raw material for synthesizing polycarboxylic acid - based cement water - reducing agents. Using high - activity catalysts and special synthesis processes, the product has a light color and good quality, with a high double - bond retention rate and higher double - bond activity than products synthesized by ordinary processes.
- Isoamyl Alcohol Polyoxyethylene Ether (TPEG)：It is non - toxic, non - irritating, and has good water solubility, and will not deteriorate by hydrolysis. TPEG series products have a high double - bond retention rate, and the molecular structure is comb - shaped with great freedom, which can be designed for molecular structure. Through a relatively simple synthesis process, high - performance water - reducing agents can be prepared. The product has the advantages of low dosage, high water - reducing rate, good fluidity and fluidity retention of concrete mixtures, low slump loss, great potential for strength - enhancing effect, and low shrinkage.
- Main Performance Indicators：Taking methylallyl polyoxyethylene ether as an example, using the internationally advanced outer - circulation spray ethoxylation (propoxylation) addition device and catalytic technology, it has the characteristics of high double - bond retention rate, stable quality, narrow molecular weight distribution, low impurity content, and high polymerization activity. The appearance is flaky, with good water solubility and stable aqueous solution properties. The hydroxyl value is 21 - 26 mgKOH/g, the unsaturation is ≥0.385 mmol/g, and the pH value of a 5% aqueous solution is 4.0 - 7.0.
- Application Fields：Mainly used in the synthesis of polycarboxylic acid high - performance water - reducing agents, widely used in high - speed railways, nuclear power, water conservancy and hydropower projects, subways, large - scale bridges, highways, port terminals, and various industrial and civil construction projects. By carrying out free - radical initiation copolymerization with double - bond - containing substances such as acrylic acid, polycarboxylic acid water - reducing agents with different performances can be formed to achieve high water reduction, high slump retention, early strength, and other properties.
- Packaging and Storage：Usually packaged in 25 - kg woven bags. The product is non - toxic and non - flammable, and can be handled according to the regulations for general chemical transportation. It should be stored in a dry, cool, and ventilated place. During transportation, avoid direct sunlight and rain, and the storage and transportation temperature should not be higher than 40℃. Under the specified storage and transportation conditions, the shelf life is generally one year.
