The material of PP filter characteristics

PP filter material characteristics of the

PP filter is made of food-grade polypropylene melt-blown PP material, it is colorless, odorless, own spotlessness, no pollution to water quality. The chemical reagents such as acid, alkali and organic solvent corrosion. PP melt-blown filter strength, when filtering import and export pressure difference of 0. 4 mpa, the filter is not out of shape. By having good filtering performance of the textile fiber yarn refined precision winding in the porous skeleton. Winding through the control of yarn winding firmness and dilute density, can be made into different precision of filter element. Can remove the suspended solids in the water and impurity particles, etc. Adopt the internationally used diameter gradient process, after heating molten, traction, receive shape and made of fiber formation in the process of thermal bonding three-dimensional micro pore structure, pore aperture by a gradient distribution outside introversion, integrating surface, deep thick fine filtration. Characteristics of

( 1) Filtration efficiency and filtration precision, filter aperture uniform density, filter efficiency of more than 99%.

（ 2) Filtering resistance is small, large flow, carrying capacity, long service life, this product in the production process of fiber diameter and clearance is adjustable, outer filter pore lining small to big, increased traffic and environmental carrying amount, the filter element is not easy to block, prolong service life.

（ 3) Own spotlessness, water pollution-free, acid and alkali and organic solvents, corrosion.

（ 4) Poor strength, import and export pressure filter more than 0. 4 mpa filter will not deformation, the temperature over 90 ℃, the filter efficiency will not decrease.

（ 5) This process has extremely high hydrophilic modification of polypropylene, can absorb ten times the weight of water, thus can be used in the oil/water separation.

PP filter can effectively remove all kinds of impurity particles in the water, because of its depth of multi-layer structure, on the carrying amount, very good, use the time will not very short, the filtering flow at work is bigger, the pressure difference is small, on the other hand it is very reassuring in safety, it does not contain any chemical agents, not only ensure the security and guarantee the health. Moreover its excellent chemical stability, on the question of cost price is very reasonable, when changing extremely handy. Finally has a large flow, corrosion resistance to high pressure, low cost, etc.
