The 21st century will be called “century of water”

Water is required in order to maintain a life. The quantity of the water which exists on the earth is called about 1,400 million km３. The amounts of fresh water which 97.5% of it is occupied in sea water, and can actually use are 0.8% of only water on the earth, such as groundwater and lakes-and-marshes water. And the amount of fresh water on the earth is fixed, and does not increase. A global water shortage, and water quality and the fountainhead pollution are advancing from the influence of development of industry, urbanization, the increase in population, etc., and safe drinking water reservation is very important towards the future. Human beings have the responsibility which uses limited resources water effectively.

In ｔhe present society, drainage from the household or the industrial drainage which be caused environmental pollution cannot be directly discharged to river.

The water treating agents of SENKA processes this pollution water in advance, and we wish environment maintenance of river.

Optimum coagulants for pollution water

SENKA DECOLORATION SYSTEM

The colored wastewater discharged from dyeing house, dyestuff factory and ink factory does not directly discharge to river because it is caused water pollution. It should be settled the colored matters and organic substance in wastewater before discharging to river. Make it possible by SENKAFLOCK series.

SENAFLOCK SERISE

(1)   De-coloration system for Dyeing Mill. and Ink manufacture

Test 1.Decoloration test of model dyes solution:
*Inorganic coagulant：P.A.C, Aluminum sulfate, Ferric sulfate.
*pH adjuster：sodium hydroxide or Slaked lime(Optimum pH：6~8)
*Senkaflock Z series：Z-150(50~200)
*Anionic high polymer coagulant：Senkaflock DS-1720A(2~5ppm)

REPELLENT F-2000 Granules

Solid form Fluorocarbon resin for solvent based Water & Oil repellent

REPELLENT F-2000 is a solid form Fluorocarbon resin to prepare solvent based Water & Oil repellents under local dilution process.

REPELLENT F-2000 (RESIN POWDER)

Appearance      :     Pale brownish white powder
Component       :     Perfluoro Alkylacryllate resin
Solubility      :     Soluble into 1.1.1.-Trichloroethane, Trichloro-Trifluoroethane, Perchlene, Toluene, 
                         ineral Turpentine(slightly cloudy)

PREPARATION OF REPELLENT F-2000 Solution

• Recommendable Dilution Formula:

          REPELLENT F-2000(RESIN POWDER)     12kgs
          1.1.1. Tri-chloroethane                              70kgs
          Ethyl Acetate                                          18kgs
         ___________________________________________
          Total                                                       100kgs

Dilution procedure:

1.Charge 70kgs of 1.1.1. Tri-chloroethane into dilution tane with heating as well as cooling device, and
   heat it up to 70’C.

   Since boiling point of 1.1.1. Tri-chloroethane is 74’C, it is recommendable to use deep bottom shape
    vessel to avoid over-flow of the solution by boiling or foaming.

2. Add 12kgs of REPELLENT F-2000(RESIN POWDER) gradually under slow stirring.

3. After REPELLENT F-2000(RESIN POWDER) dissolve completely, cool it down under 40’C and add
    Ethyl acetate at room temperature and mix them well.

Note: Ethyle Acetate is highly inflammable and so, it should by added at room temperature(25C’) with
          proper ventilation. Then, seal Cap of container tightly.

4. Filter the solution to remove insoluble matters and pack into closed seal container. 

Remark:
Since diluents are inflammable solvents, non-explosive machinery is required and handle to be care in whole dilution process.

Storage of diluted solution to be in dark/cool place and catching the fire.

General properties and Application for Solvent based Water & Oil Repellents prepared with REPELLENT 2000 (Solid resin) :

REPELLENT F-2000 Solution is a solvent based Fluorocarbon resin Water and Oil repellent for textile finishing, leather coating etc.

Properties :
Appearance      :     Pale yellowish transparent/semi-transparentliquid
Main component     :     Fluoro-polymer derivatives
Solubility      :     soluble in hydrocarbons like Benzene,Toluene, Xylene and Mineral Turpentine Oil.  

Features :

1. REPELLENT F-2000 Solution is suitable to give water/oil repellency to the substrates, which can not
    be treated with aqueous type water/oil repellents as well as treated material can not have heat as
    curing.

2. REPELLENT F-2000 Solution is giving good water and oil repellency to textile as well as leather
    products and so on.

3. REPELLENT F-2000 Solution has good compatibility to conventional solvent type resin solution like
    Acrylic or Polyurethane resin solution and coated surface with REPELLENT F-2000 Solution will have
    good water/oil repellency.

Application:

• Dosage for general water oil repellent finishing;
