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.

In many applications, the use of surfactants in combination with conventional surfactants not only reduces the dosage of both, but also reduces the cost of the product and achieving good performance .This is the "synergistic effect" of the surfactant. It will show very good performance when used as a wetting agent, leveling agent in coatings, inks, floor waxes and other products. But fluorocarbon surfactants do not show good performance as well as ordinary hydrocarbon surfactants in reducing the interfacial tension of liquid .

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.

In January 19, all staff attended the Dangerous Chemicals Safety Training in Haisen headquarter meeting room and studied systematically the Dangerous Chemicals’ definition, variety, case and safeguard etc. Haisen Chemical produce AEO, JFC and Peregal series professionally. These series belong to Dangerous Chemicals. So all staff must know the safeguard.

In order to better promote Haisen’s new products in 2018, the network department has been in the brain storm for several days. Haisen Chemical launch four new products this year, including Fluorinated Polyether Siloxane, Fluorine Silicon Oil, Polyetheramine PEA and ASA Film. Welcome to inquiry!

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

As a EO, PO user and producer of isopropanolamine, water reducer and surfactant, Haisen Chemical concerned a lot about the use and storage of chemical products on a daily basis. Personal safety should always be in the first place, chemical companies should pay attention to safe use, production, storage of chemical products.

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
