Fluorocarbon surfactants- A class of substances that can significantly reduce the surface tension of a solvent at very low concentrations . Fluorocarbon surfactants are the most important species of specialty surfactants, which means that the hydrogen atoms in the hydrocarbon chains of the hydrocarbon surfactants are totally or partially replaced by fluorine atoms, that is, the fluorocarbon chains replace the hydrocarbon chains. Therefore, the surface The non-polar groups in the active agent are not only hydrophobic but also oleophobic.

The Natural Phenol polyethoxylates ,made from natural extract and EO ,could be Used in health and personal care products.

Ethoxylated Natural Phenolic lipids is a natural surfactant made from natural extract and EO (Ethylene Oxide) which very easy degrade in natural environment. The Ethoxylated Natural Phenolic lipid have good wetting, dirty remove power being used in various sectors of industries frequently.

Due to the special efficacy of renewable raw material production and green environmental protection concept, Natural Phenol Polyoxyethylene has attracted more and more attention recently. This series are made of natural plant material, which are environmental without nonyl phenol after biodegradation. They have no effect to the endocrine system and will not cause harm to the ecological. Ethoxylated Natural Phenol Liquids 10 EO 7810 and Ethoxylated Natural Phenol Liquid 7815 are highly biodegradation and environment friendly type of non-surface-active agents and can be widely used in the industry or civil detergent industry.

Safe and efficient use of polycarboxylate superplasticizer must pay attention to the some problems, like the dosage and the proportion of the materials and avoid to use polycarboxylate superplasticizer with some admixtures, do more research on the polycarboxylate superplastcizer application is a must.

Our fluorosurfactant additives could effective help fire fighting foam form a uniform, aqueous film that quickly spreads over the surface of burning polar solvents and hydrocarbons. Application Features: 1.Application for Rapid extinguisher 2.effective reduced risk of burn-back 3.The fire fighting Foam will maintains thermal and chemical stability while in contact with hydrocarbons. 4.Increased stability of fire fighting foam for polar liquids 5.effective form a physical barrier against flammable vapors

Our country stipulates that the average daily outdoor temperature for 5 days in a row stable below 5 ° C under the conditions of concrete construction, that is, the construction of concrete in winter. Concrete winter construction additives used are: early strength agent, antifreeze agent, water reducer and air entraining agent, can play early strength, frost resistance, procoagulant, water reduction and reduce the role of freezing point. This is an effective method of concrete construction in winter.

With low molecular weight (n=1000~4000) of PEG solution dipping wood, make lumber fully swelling. After drying, PEG with waxy retained in the cell wall, make the cell wall in the expansion state, thus improve the wood dimensional stability.

Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction.Concrete slump test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. The slump test i

IntroductionImportant limitations of mineral trioxide aggregate for use in clinical procedures are extended setting time and difficult handling characteristics. The removal of gypsum at the end stage of the Portland cement manufacturing process and polycarboxylate superplasticizer admixture may solv
