At our coal preparation, metallurgy, chemical industry, environmental protection and other industries using the disc vacuum filter, vacuum drum filters, centrifuges, belt filter and a plate and frame filter press for suspension of solid-liquid separation, large Most multifilament woven cloth and 90 years before the introduction of foreign equipment manufacturers of non-woven filter blanket acupuncture were separated. But the international community, since the 1990s began to use silk fabric solid-liquid separation efficiency improved significantly. However, due to imports of silk fabric is expensive, only a handful of domestic high technology solid-liquid separation unit only requires the use of imported silk fabric. 2 monofilament filter cloth performance silk fabric with synthetic fiber as raw material, made of nylon (PA), polyester (PET), polypropylene (PP) and ethylene (PE) monofilament woven. Ordinary silk fabric weaving technology is not complicated, general domestic industrial fabric manufacturers can produce, but to produce a solid-liquid separation process to meet the requirements of high-density special silk fabric, only Wuxian City, Jiangsu Province Quartet special fabric Ltd.. The company produces Z53 monofilament nylon cloth in 1996 by Suzhou City Textile Quality Supervision, CMA measured breaking strength of the product, elongation, thickness, ventilation volume, wear rate and bursting force of the main technical parameters are leading on similar domestic products. China University of Mining experts analysis that: the level of product technology closer to similar imported silk fabric. 3 Performance comparison of several commonly used multifilament filter cloth woven cloth due soon at the solid-liquid separation medium abrasion fluff, so life is very short. Acupuncture non-woven filter mat made of polypropylene fiber layer, inner layer plus a nylon woven wire reinforcing mesh, in a laminated surface to form a thin film by hot pressing, increase the intensity ratio of multifilament yarn woven fabric, improve dialysis and smoothness, which to some extent, improve the dewatering effect and cloth filter life, but the use of the material to form a blocking motion The author analyzes the designers conceived, because no more than two aspects:? First, from machinery aspect. Using angle without the use of flat steel, it is nothing more than increase the strength of the pressing plate. According to my experience that the probability is very small plate fracture; the second is from the process effectiveness analysis. Attempts to increase the resistance movement screen surface materials, reducing material layer velocity to improve screening efficiency of dehydration, but less so in actual production. Since the material layer is too thick, dialysis weakened, but screening efficiency deteriorates.
