- Reconstruction of old cement concrete pavement.Domestic most of the original road pavement structure of cement concrete panel, this kind of structure joints and cracks easily, eventually lead to diseases such as fault sets, escapes, pavement damage, and influence the comfort of driving.Product & Technology March 23, 2018
- China Concrete admixtures Polycarboxylate superplasticizer PCEWhat are Admixtures ?They are natural or manufactured chemicals which are added to the concrete before or during mixing.Commonly used are Air-entraining agents, Water reducers, Water-reducing retarders and Accelerators.Why are they Used ?They are used to give special properties to fresh or hardenedProduct & Technology March 22, 2018
- Propylene Oxide POpolyols, propylene glycols and propylene glycol ethers are three main derivatives markets of polypropylene oxide (PO)major part of propylene oxide is produced by chlorohydrin propylene oxide (CHPO) process; other technologies include propylene oxide/styrene monomer (POSM), propylene oxide tertiary bProduct & Technology March 22, 2018
- China Surfactant Alcohol Ethoxylates (AE or AEO)Alcohol Ethoxylates (AE or AEO) are a major class of non-ionic surfactants.Fatty Alcohol Ethoxylates are produced by reacting natural fatty alcohol with Ethylene Oxide (EO). Regarding chemical structure of alcohol ethoxylate, the more the ethylene oxide groups added to the fatty alcohol, the higherProduct & Technology March 22, 2018
- The price trend of ethylene oxide (EO)The agency has investigated the recent trend of ethylene oxide in nine production companies and 11 downstream users. Three of them think the price of ethylene oxide will fall this week, accounting for about 15%.There are 12 users who believe that the price of ethylene oxide will be stable this week,Product & Technology March 22, 2018
- Concrete Admixtures And Cement AdaptabilityCommercial concrete, especially high-strength and high-performance concrete with large flowability and low water-to-cement ratio, has an excessive loss of slump due to poor adaptability of admixtures and cement during transportation and construction. It not only affects the construction of concrete, construction quality, and even the inability to pump construction, but also will affect the quality of hardened concrete, thus proposed a variety of methods to improve the admixture and cement adaptability to control the concrete slump loss.Product & Technology March 22, 2018
- Haisen Surfactant chemicals for paint industrySurfactants affect a wide array of physical properties in paints. Surfactants affect the behavior of a paint not only during the lifetime of the formed coating but also the initial aggregation and film formation of the paint. Surfactants are also used to stabilize the dispersion of polymer particlesProduct & Technology March 19, 2018
- Effect of Calcium Nitrate, Triethanolamine and Triisopropanolamine on Compressive Strength of MortarsChemical admixtures are used in concrete for various purposes such as water reducing, plasticizing, air entraining, bonding, viscosity modifying, colouring, corrosion inhibiting, permeability reducing, accelerating or retarding the initial setting time, and shrinkage reducing. The use of chemical adProduct & Technology March 19, 2018
- Polyurea Waterproofing Material Uses Polyetheramines(PEA)Polyether amine (PEA): a class of polymer with polyether structure with the terminal active functional group as an amine group. Has been widely used in the production of large composite materials, spraying polyurea and epoxy resin curing agent and automobile gasoline detergent etc.Product & Technology March 19, 2018
- Haisen Concrete admixtures for construction chemicalsAdmixtures are those ingredients in concrete other than portland cement, water, and aggregates that are added to the mixture immediately before or during mixing . Admixtures can be classified by function as follows: 1. Air-entraining admixtures 2. Water-reducing admixtures 3. Plasticizers 4. AccelerProduct & Technology March 19, 2018
