Phosphate ester flame retardants are humanmade chemicals added to consumer and industrial products for the purpose of reducing flammability. Phosphate ester flame retardants are composed of a group of chemicals with similar properties but slightly different structures. Phosphate esters are typically liquids at room temperature; however, some are solids.

May 25, 2017· These products are called Deers. Deers are needed in the concrete when the thickening agents cause air to be trapped inside creating the . Common deformers used for this situation are Tributyl Phosphate (TBP). The thickening agent and deer (TBP) have a direct relationship in terms of usage ( more thickening agent used the ...
Tributyl phosphate (TBP) is an organophosphorous compound, manufactured by esterification of orthophosphoric acid with nbutanol. This colorless and odorless liquid is used in many different industries as extracting solvent, deing agent, flame retardant and plasticizer.
Concrete reinforced with wt% MWCNTs with SDS as surfactant and tributyl Phosphate deer. Comparing the SEM micrographs (Figures 4 and 5 ) demonstrates that the elimination of the deer in the concrete mixing process results in a lot of unwanted air bubbles and may decrease the mechanical properties of concrete.
Tributyl phosphate is also used in the making of plastics and in cement casings for oil wells. EXPOSURE: Exposure to tributyl phosphate can be from ingestion, inhalation, or skin or eye contact. This exposure will most often happen from occupational use of hydraulic fluid.
Information on: tributyl phosphate Indication of possible carcinogenic effect in animal tests. Experiences in humans: According to experience, the product is considered to be harmless to health if used in the correct manner. Other Information: The product has not been tested. ...
Dec 30, 2014· Microfibers (such as steel, glass, polymeric or carbon) have been extensively used to reinforce cement and concrete in the past decades. They have relatively large aspect ratios ranging from 10 to 1000 and their material properties are presented in Table fiber is commonly used in the construction industry for retrofitting steel and concrete structures owing to its considerable elastic ...

The present invention is directed to a deing agent for use with polycarboxylate based admixtures for concrete. The deing agent is comprised of tributyl phosphate, an alkylaryl sulfonic acid metallic salt and a modified alkylpolyalcoxy ester. Tributyl phosphate is a phosphate ester based deer and the modified alkylpolyalcoxy ester is an air detraining agent.
Dibutyl phosphate, waterinsoluble alcohols, waterinsoluble esters of carbonic and boric acids as well as silicones may also do the job. Obviously they must be used judiciously for the concrete to end up with the right amount of air. Tributyl phosphate, silicones, water insoluble alcohols are the most used airdetraining admixtures.

Application of Tributyl phosphate TBP 1) Tributyl phosphate TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate. It forms stable hydrophobic complexes with some metals; these complexes are soluble in organic solvents as well as supercritical CO2. 2) The major uses of Tributyl
The present invention is directed to a deing agent for use with polycarboxylate based admixtures for concrete. The deing agent is comprised of tributyl phosphate, an alkylaryl sulfonic acid metallic salt and a modified alkylpolyalcoxyester. Tributyl phosphate is a phosphate ester based deer and the modified alkylpolyalcoxyester is an air detraining agent.
Triisobutyl phosphate is a very strong solvent used for liquefying concrete, textile auxiliaries, paper coating compounds, etc. Tri iso butyl phosphate (TiBP) is a very strong, polar solvent. It is mainly used as an antiing agent in various aqueous systems where it has the ability to both destroy and act as a inhibitor.

Brief description The alkyl phosphates family consists of a group of different phosphoric esters. They are used as highly polar solvents for different extraction processes, serve as deers for paints or concrete additives for example, are used as flame retardants or perform tasks in a variety of chemical synthesis processes.
Typical concrete slab track designs consist of a concrete track slab placed on top of a concrete bed, with a cushion layer in between to help dampen the system (Fig. 1).
Jul 01, 1973· The most widely used airdetrainer is tributyl phosphate. Dibutyl phosphate, waterinsoluble alcohols, waterinsoluble esters of carbonic and boric acids as well as silicones may also do the job. Obviously they must be used judiciously for the concrete to end up with the right amount of air.
As the deing additives used mineral reference to ha oil is a mixture of Slorm substance 99,6%, density 898 g/l, which represents the viscous liquid amber, iridescent colors or tributyl phosphate (TU ), which is a viscous liquid and ensuring the uniform application of the composition, and precluding the formation of in the ...
Jun 30, 2006· The coarse aggregate used is crushed diabase with diameter of 5–25 mm. UNF waterreducing agent (one kind of βnaphthalene sulfonic acid and formaldehyde condensates, China) is employed to aid the dispersion of nanoparticles in concrete and achieve good workability of concrete. The deer, tributyl phosphate (made in China) is used to ...
Mainly used as a flame retardant in aircraft hydraulic fluid, which can contain 25 to 75% TBP; Also used as a solvent (rare earth extraction and nuclear fuel cycle), plasticizer, carrier for fluorescent dyes, and anti agent (cement casings for oil wells); [ACGIH] Used as an antiing agent (concrete, textile, and paper industries); [HSDB]
Our main product is planned to be Tributyl Phosphate (CAS number: which is odourless liquid, mainly used for purification of Water, Phosphoric and Nitric acid, Rare earth metals extraction, special concrete admixtures, brake fluids etc. Main characteristic of TBP is that it bonds hard metals and impurities, so then they can be removed from ...
