| 针刺无纺布加工程序 Processing procedure of needled nonwoven fabric 是以涤纶、丙纶原料制造，经粗梳、精梳、预针刺，主针刺。中心加网布夹层，再经双道核理，气流成网针刺复合成布，后压滤布具有三维结构，经热定型，烧毛后，在表面最经化学油剂处理，使滤布外表光滑，微孔分布均匀，从表面看该产品的密度好，两面表面光洁和透气程度较好，在板框压缩机上过滤使用证明，可使用高强压力，过滤精度高达4微米以内，可根据用户需要提供丙纶和涤纶两种原料。实践证明无纺过滤布在板框压滤时性能更好：例选煤厂的煤泥处理，钢铁厂废水处理。在啤酒厂、印染厂废水处理。如用其他规格滤布都会出现滤饼压不干，又难以脱落的问题，用无纺滤布后，滤饼在滤机压力到达10kg-12kg时就相当干燥，而滤机开框时滤饼会自动脱落。用户在选择无纺滤布时，主要根据透气量，过滤精度、伸长率等来考虑不同厚度、质量的无纺滤布，产品参数请点涤纶针刺毡和丙纶针刺毡，规格品种均可制定。 It is made of polyester and polypropylene raw materials, and is mainly needled by carding, combing and pre needling. The center is interlayer with net cloth, and then through the double channel core, the air flow is formed by the net needle, and the back pressure filter fabric has three dimensional structure. After heat setting, the surface is smoothed and the micropore is evenly distributed. The surface of the product is good, the surface of the two surfaces is smooth and good in air permeability. It is proved that the high strength pressure can be used on the plate and frame compressor. The precision of the filter can be as high as 4 microns. The two kinds of polypropylene and polyester fiber can be provided according to the needs of the user. Practice has proved that non-woven filter cloth performs better in plate and frame pressure filtration: coal slurry treatment in a coal preparation plant and wastewater treatment in iron and steel works. Wastewater treatment in the brewery and printing and dyeing plant. If the filter cake is not dry, and it is difficult to fall off, the filter cake is dry when the filter pressure reaches 10kg-12kg, and the filter cake will fall off automatically when the filter is opened. When users choose non-woven filter cloth, the non woven filter cloth with different thickness and quality is considered mainly according to the air permeability, filtration accuracy and elongation. 针刺无纺布系列产品是经过精细梳理成型，多次精密针刺或加以适当热轧处理而成。在引进国内外二条高精度针刺生产线的基础上，选用优质纤维。通过不同生产工艺配合，以及不同材料的配搭，目前市场上流通数百种不同的产品，其中主要有：土工布、土工膜、戟绒布、音箱毯、电热毯棉、绣花棉、服装棉、圣诞工艺品，人革基布、过滤材料专用布。 Needle punched nonwoven fabrics are made by fine carding, precision needling or hot rolling. Based on the introduction of two high-precision needle punching lines at home and abroad, high quality fibers are selected. Through the combination of different production processes and different materials, there are hundreds of different products in the market, including geotextiles, geomembrane, halberd flannelette, sound box blanket, electric blanket cotton, embroidered cotton, garment cotton, Christmas crafts, human leather base cloth and filter material special cloth. |
