• PAPER SIZING CHEMICALS

    DİPER has entered into the paper and board industry with internal sizes in the 1980’s. We are the first and the only company which produces and exports a wide range of paper sizes in Turkey. We serve our clients by producing and supplying acidic, neutral and alkaline sizes depending on the customer’s machine requirements and also by providing technical support.

    The Topsize dispersions series developed at our R&D laboratory, which is the first rosin dispersion in the world stabilized with a polymer, is a very successful example of innovation.

    Wet-End Sizes

    Dispersion Type : Topsize Series

     

    Synthetic Sizes (Alkyl Ketene Dimer)

    Starch-Based AKD : DR Size CS Series

    Polymer-Based AKD : DR Size CP Series

     

    Surface Sizes

    Anionic Surface Sizes : Dipol Series

    Cationic Surface Sizes : Persize Series

  • RETENTION AND DRAINAGE CHEMICALS

    The quality of recycled paper which deteriorates from day to day has caused paper producers to search for solutions that will improve retention, provide better formation, enable faster drainage and result in better runnability. In order to meet such requirements, suitable solutions to the varying needs of individual plants are tested together at the customer’s laboratories. In this way, the chemicals which perform the best in a given system is determined, and the results obtained on the machine is followed up by our technical team.

    Based on our experience which exceeds 42 years, we obtain optimal results in retention systems by feeding various chemicals, either individually, or in combinations  of two or three of these products.

    Anionic Trash Catchers (ATC)

    DIPFIX Series

    Provides and increases the retention of fines and the anionic trash on the paper thus keeping the system clean.

    Polymers

    DIPRET Series

    Increases retention by forming bigger flocs.

    Colloidal Silica

    RITCHO MP Series

    Forms tighter and smaller flocs, and increases drainage speed.

    Advantages:

    • Fast drainage
    • Higher ash retention and total retention
    • Better formation
    • Better runnability
    • Cleaner system
  • FELT - WIRE CONDITIONING AND CLEANING CHEMICALS

    The contamination that comes via recycled paper, as well as the fillers and chemicals used in the system, clogs the wires and felts over time thus causing stoppages for cleaning. The following are our chemicals used to minimize such effects:

    DR CON Series : Felt and wire conditioning chemicals that form a protective film on the surface through continuous use during paper production. 

    DIPFELT Series : Felt and wire cleaning chemicals used during short-term stoppages of the machine.

  • STICKY CONTROL CHEMICALS

    When used continuously, RITHCO CLEAN PI is an effective product for preventing formation of stickies in pulp tanks, lines and machines.

    Advantages :

    • Better runnability on felts and wires
    • Less breaks
    • Cleaner cylinders in the drying section
    • Cleaner paper
    • Reduced use of biocides
    • Less bacterial spots
    • 100% biodegradable according to MITI-Test (OECD 302 B)
  • TISSUE CHEMICALS

    • Wet-Strength Resins
    • Dry-Strength Chemicals
    • Softeners
    • Deinking Chemicals
    • Anti-dusting Agents
  • PAPER DYES

    Send samples of your raw materials and the desired color, and let DİPER work out the optimal for you.

    Our products :

    • Basic Dyes
    • Direct Dyes
  • DEFOAMERS

    The whole range of defoamers for internal and surface applications, and for pulp preparation:

    • Water-based Defoamers
    • Oil-based Defoamers
    • Silicone-based Defoamers
  • RİTHCO PAPERTECH EKİPMANI

    The Airjec-System is a hydrodynamic solution for the integration of micro-bubbles of air into a liquid.

    The RITHCO technology employs a diffusor which produces a broad range of bubble sizes, and the different bubble sizes function selectively in the flotation of fibers, ashes, residual and broke fibers, stickies, resins and other components. The advantage of the Airjec Technology is providing more dissolved air than conventional aeration systems.

    You can reduce your costs with Airjec Technology via energy savings

    • In Flotation (DAF) Units
    • In Waste Water Treatment;

    and by Using the patented RV-System in Deinking Process for effectual floating of   fibers which results in several important savings and advantages such as:

    • Better/cleaner fibers
    • Reduction of microstickies
    • Reduced costs due to higher whiteness obtained even when using lower quality raw materials.

    Our technical sales and applications engineers can inform you on the RITHCO system which is being used with great advantage at nearly 300 mills (close to 430 units) in about 25 countries.
