PA6 or PA66 Filter Meshes?

SHARE has been approached by clients from different industries, asking for filter meshes from us for their particular applications. As saying goes, there is no bad material, only bad material for particular application. Here we would like to have a small talk on the most important filter material: Polyamide 6 and Polyamide 66. PA 6 […]

Principles of Filtration

Chemical Compatibility Chemical Compatibility indicates the ability of the filter media to maintain its structural integrity and function with exposure to certain chemical(s). This means that the filter will not exhibit pore-structure impairment, the media will not shed particles or fibers, and extractables will not be present in the filtered sample. In addition to filter material, […]

Felt Filter Bags vs Monofilament Mesh Filter Bags

When referring to the selection of filter bags, several critical principles have to be followed, such as chemical compatibility, hydrophilic or hydrophobic, filter rating, binding, extractable, thermal stability, flow rate and throughput. Here we will talk about two major filter media: Felt Filter and Mesh (Mono-fialment) Filter. Felt Filter Media: Felt is made from synthetic […]

How to control mesh quality

When checking the quality of filter meshes, we will need to take tensile strength, mesh count, thread diameter as well as open area into consideration, other than these parameters, surface treatment is also measured when meshes are selected for specific filtration application. Yarn Inspection Raw material for filter mesh is the yarn (monofilament or multifilament), […]

How to select a proper filter bags

To make the filter bags perform to the optimum at the vessel, you need to know how to choose the right filter bags for the filtration system. Filter Fabrics Polypropylene, Polyester, Nomex and Nylon are the four major synthetic fiber-made filter media used for making filter bags, which are able to be made of needle-punched […]

Screen Printing Mesh Brief Introduction

Mesh materials  The two most popular mesh materials in use today are polyester and stainless steel. In the past other materials were used, among them silk, which is why so many uninformed sources still insist on referring to screenprinting as “silkscreen printing.” For many years, nylon also enjoyed considerable popularity as a screen material and […]

Chemical Resistance of Major Fibers in Filtration Field

When comes to the selection of filter meshes or molded plastic filters, the first thing coming out of our mind is the micron rating, because we need filters/strainers to sift our particles from entering into fluid that we need to purify. However, sometimes, due to plastic resin’s chemical properties, we cannot just take micron rating […]

How a synthetic woven mesh is made

To weave a precison woven mesh (open mesh with square mesh holes) will go through several procedures as below: Step 1: Yarn ispsected and tested in terms of strength, overall thickness, surface properties (Core Yarn) Step 2: Warping and Sizing Step 3: Drawing in heddles and reeds Step 4: Weaving Step 5: Washing Step 6: […]

Major Parameters of Filter Meshes

Major Parameters of Woven Filter Meshes 1). Yarn Diameter Nominal dnom: The diameter dnom is measured on the thread before weaving 2). Mesh Count n [n/cm]: The mesh count n stands for the number of threads per centimeter or per inch. 3). Weave Type: Open Mesh major two weaving types are PW (Plain Weave 1: […]

Surface Filtration VS Depth Filtration

Surface Filtration implies that particles are intercepted mostly on the surface of the media, forming a layer of material “filter cake” that increases the efficiency or fineness of particles retained.  Generally speaking, this type of filter media is referred to as having a “nominal retention”; perhaps initially being 60% to 70% efficient at retaining the targeted […]
