Q: How to choose the right product for filtration?
Here are the factors to consider:
Application.
Particle size to be selected.
Filter cloth working temperature.
Filter cloth working pH value.
Type of filter machine.
Q: What is particle size?
Particle size is the diameter of fine particles in the filtrate, determined by the choice of filter cloth.
Q: What is pH value and why consider it?
pH is a measure of acidity, on a scale that ranges from 0 to 14, from strong acid (lower value) through neutral (7) to alkaline (higher value). The pH affects the choice of filter cloth material. For example, PP works across the range but PES is recommended only from pH=3 to pH = 9.
Q: What is fabric? What are the main ways to make it?
Fabrics are flat and soft pieces made up of slender and flexible objects that are crossed, knotted and connected.
Mainly classification:
Weaving: made up of yarns with cross-relationship.
Knitting: made up of yarns with knot-relationship.
Non-woven: made up of yarns and fibers with connection-relationship.
Q: What are the types of yarn?
Yarns consist of staple fibers (e.g. cotton, polyester staple) or filaments(e.g. multifilaments, monofilaments). Spun yarns consist of staple fibers, which are held together by twisting the fibers during spinning.
Monofilament consists of a single filament yarn, a fiber obtained by continuous spinning.
Multifilament yarns consist of slender filaments and a bundle of slender monofilaments. (Bolian multifilaments 0 twist)
Twisted yarns are two or more yarns twisted together into one twisted yarn.
Q: What is industrial filter cloth? What are the main materials?
Industrial filter cloth is a filter media woven from natural fibers and synthetic fibers, belonging to industrial textiles. Main materials are Polypropylene, Polyester, Nylon, Vinylon, Aramid, Full-Cotton, etc. Among them, polypropylene and polyester are more commonly used. Plain, twill, satin, and non-woven needles are main weaving methods.
Q: What are the main applications of industrial filter cloths?
Industrial filter cloth is mainly applied to liquid-solid separation and gas-solid separation. Liquid-solid separation is widely used in mining, chemicals, metallurgy, non-metallic minerals, food, medical and other fields. Gas-solid separation is mainly used in ironworks, steelworks, ferroalloy factories, refractory factories, foundry and other flue gas dust removal systems and flue gas filtration.
Q: What is the definition of breaking strength?
Breaking strength: the maximum force in the process of pulling off the specimen.
Breaking elongation: the breaking elongation is calculated according to the elongation at the maximum force during the stretching process and initial length.
Breaking time: the time corresponding to the breaking elongation. (The stretching speed is constant.)
