Introduction of Concrete Additives

Concrete additives are chemicals and materials blended into the cement to alter its performance. Additives provide a specific benefit for a particular job. Liquid additives used during cement grinding improve the strength of the cement. Concrete bonding additive bonds old concrete to new for interior and exterior jobs like wall capping and resurfacing. Color additives give concrete a stylish look. Whatever the job, concrete additives help get it done.

Cold weather concrete has superior properties to concrete placed in hot weather. At low temperatures, though, concrete sets and gains strength more slowly because the cement doesn't hydrate as fast. Setting time is increased about one-third for each 10 degree decrease in concrete temperature down to 40 degrees Fahrenheit. Accelerating admixtures can help to offset these effects of low temperatures on setting and strength gain. They should meet the requirements of ASTM C 494, Standard Specifications for Chemical Admixtures for Concrete.

Sinofloc provides concrete additives for cold weather and concrete additives for waterproofing, which can be widely used in Construction.

Sinofloc Polyacrylamide Flocculants for Water Treatment

Treatment of natural water and sewage is closely linked to preservation of the environment and is thus an actual present day problem. During the last decades there have been noticed substantial increase of the content of heavy metals, mineral oil, poorly-oxidable organic compounds, synthetic surfactants, pesticides and other pollutants from insufficiently treated effluents of industrial and municipal enterprises in open water reservoirs. In spite of the great number of elaborations reported in literature, the problem of natural water and sewage treatment has not yet been solved. Hence, the technology of water treatment needs further perfection which mainly includes the ways of intensive use of reagents, in particular flocculants. For these purposes water-soluble high-molecular compounds among which the most widespread and universal are polyacrylamide flocculants are used. As a result of their application the efficiency of removal of heavy metals is increased by 95%, compounds of phos

Product Selection Of Sinofloc Polyacrylamide

Sinofloc has developed a wide range of polymers , both in dry powder and liquid emulsion forms, to cover the vast majority of existing conditions within the various industries (water treatment, mining processing, oil & gas etc.). Sinofloc polyacrylamides range from cationic to non-ionic and anionic in nature, and the selection of the best product depends on several parameters. General guidelines regarding typical product selection for a given application used in a specific industrial can be found on the individual product technical data sheets, as well as in the sections regarding the industries we serve. However these are not to be taken literally. In order to select the optimum product for a specific application, it is essential that laboratory testwork followed by plant trials are carried out. Initial laboratory testwork will give an indication of the best product and approximate dosage, which will then need to be confirmed with more accuracy by running plant trials

Sinofloc Polyacrylamide Used As Oil Field Additives

Sinofloc polyacrylamide flocculants has good performance in thickening, flocculation, and fluid rheology modifiers, which is widely used in drilling, plugging, water acidification, fracturing, wash well, completion, drag reduction, scale and drive oil . Currently many oil fields have entered the field of secondary, tertiary recovery, reservoir depth of 1000m above generally in some reservoir depth of 7000m, heterogeneity and offshore oilfield in oil production operations to the proposed more stringent conditions, deep oil and offshore oil corresponding to PAM also raised new demands to shear resistance, high temperature (above 100 ℃ up to 200 ℃), resistance to calcium ion, magnesium ion, seawater degradation. Our products show a good performance in Enhanced oil recovery (EOR). Partially hydrolyzed polyacrylamide (HPAM) is often used as drilling adjusting agent, which consists of polyacrylamide hydrolysis. Its role is to regulate the rheology of the drilling fluid to carry c
