Hydrochloric Acid

Hydrochloric acid is a solution of hydrogen chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid. Hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic.

Sodium Hydrosulfide

Sodium hydrosulfide is a useful reagent for the synthesis of organic and inorganic sulfur compounds. It is a colorless solid that typically smells like H2S due to hydrolysis by atmospheric moisture. Its main uses are in paper manufacture as a makeup chemical for sulfur used in the Kraft process, as a flotation agent in copper mining where it is used to activate oxide mineral species, and in the leather industry for the removal of hair from hides.

Properties Suppliers
Sodium Hypochlorite

Sodium Hypochlorite is an alkaline, corrosive, light yellow solution. It is formed when caustic soda (NaOH) and chlorine (Cl2) react. It is widely used for its bleaching, disinfecting and oxidizing properties. Sodium Hypochlorite shows, as well as chlorine, a very high reactivity and oxidizing power, but as a solution it is much easier to handle than chlorine. Sodium hypochlorite reacts with hydrochloric acid to release chlorine gas. It decomposes when heated to form sodium chlorate and sodium chloride. Sodium hypochlorite reacts with most nitrogen compounds to form volatile chloramines, dichloramines, and nitrogen trichloride. Sodium Hypochlorite is used as bleaching agent for textile fibers and paper,surfactant, swimming pool disinfectant, drinking and process water disinfectant,oxidizing agent and in production of cleaning and disinfecting agents.

Properties Suppliers
aluminium sulfate

Aluminium sulfate is an industrial chemical used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. It is used as a mordant in dyeing and printing textiles. Aluminium sulfate is the active ingredient of some antiperspirants. It is usually found in baking powder, where there is controversy over its use due to concern regarding the safety of adding aluminium to the diet. In construction industry it is used as waterproofing agent and accelerator in concrete. Another use is a foaming agent in fire fighting foam. It is also used in styptic pencils, and pain relief from stings and bites. It can also be very effective as a molluscicide, killing spanish slugs.

Oxidized starch Technical 98%

Oxidized starch For Papermaking

oxidized starch from natural corn starch by oxidation technology and the latest, afterwashing and dehydration drying fine screening - packaging process. Mainly used in paper surface sizing of paper, board.

 

1 Character

1 The paste viscosity, good fluidity, strong adhesion, high stability. Do not use a long timecaused by fluctuation of viscosity is too large or the system pressure increases.

1 the finished film, film flexibility, abrasion resistance, excellent transparency.

1 The product has high whiteness, impurity content is very bottom, hydrophilic particlesincreases, lower gelatinization temperature, energy saving.

1 Product viscosity in user requirements within the scope of the special processing; other indicators can be processed according to user requirements.

1 At the same time, the oxidized starch is used in the textile, food industry.

 

1 How to use.a.     under the condition of stirring, the product is added in the cold water, transferred into the 10% suspension emulsion concentration, heating to 90 deg. C, heat 15-20 minutes to fully gelatinization, add water to dilute the standby.

1 Mixed in with other sizing agent, should be added in the process of dilution of gelatinization.

1 In use, the reflux liquid to be filtered, reflux tank should be kept clean, paste temperatureto maintain stability.
