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
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:
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.
When used continuously, RITHCO CLEAN PI is an effective product for preventing formation of stickies in pulp tanks, lines and machines.
Advantages :
Send samples of your raw materials and the desired color, and let DİPER work out the optimal for you.
Our products :
The whole range of defoamers for internal and surface applications, and for pulp preparation:
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
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:
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.
