Preparation of water-membrane In preparation of this membrane is water the main objective is to develop the potential of 2 fibers by tissue paper to grinding and improved properties, according to the purpose of use by mixing different types of additives, or according to a defined ratio of this mixture is called the "water culture" or "stock" (stock) membrane that is made of paper of all types must be passed to crush more or less close to the quality of the tissue. Some types of tissue do not need grinding, such as wood pulp grinder and merge. In the preparation of a water membrane contains sections that acts to grind and mix with the sort operation as follows:1. to distribute the fibers so that the tissue distribution (defibering) fibers separated in water by using a device called a Hydra fold perfect (hydrapulper.)2. grind the tissue to tissue (refining) crushed fibers branch to improve the electric potential of a bond between the fibers. The device is used in RI fire Manor (refiner).3. mix the water membrane (blending), become a fill additives into the tissue through the crushing and mixed in to propeller stirring tank tissue is stored in a machine called a chine chet (the machine chest).4. separate the impurities from the water membrane (screening and cleaning) by using a flat screen or a screener to pressure the material fibers are larger, and then passed into the Zen cleaner called click fio cleaner (cleaner chetrifugal) separate another material removed by using specific gravity.5. the concentration of membrane water control (consistency regulator) to control, water constant viscous tissue.
