PPS fiber has high temperature resistance, complete strength retention, and inherent chemical resistance, which can maintain good filtration performance in harsh environments and achieve ideal service life. PPS fibers have poor antioxidant capacity at high temperatures and cannot be used in situations with high oxygen content. PPS filter felt is an ideal high-temperature filtration material, with a lower price than high-temperature filter media such as Metas, making it an ideal substitute for Metas filter media.<\/p>\n
Our factory imports Japanese Toray PPS fiber and produces PPS needle punched felt with all indicators meeting international standards. In response to the excellent thermoplasticity of PPS fibers, our factory uses imported fully automatic hot melt technology to produce PPS hot melt bags. The bottom, sides, and collar connections of the filter bags are all welded by hot melt method, avoiding the leakage problems caused by pinholes and uneven materials in traditional seam filter bags, as well as fiber detachment problems, which are all solved by this fully hot melt welded filter bag. The high-precision wireless seam filter bag adopts digital same position multi-point welding equipment to ensure that the welding at each point remains the strongest and most consistent.<\/p>\n
PPS needle felt characteristics<\/strong>:<\/p>\n 1\u3001 The working temperature is 170 \u2103, the short-term working temperature is 232 \u2103, the melting point is 285 \u2103, and the ultimate oxygen index is 34-35. PPS fiber has excellent thermoplasticity, and PPS filter bags can be made into hot melt bags.<\/p>\n Application:<\/strong><\/p>\n PPS needle punched felt is currently one of the main filter materials used for pulse cleaning bag filters in coal-fired power plant boilers. PPS filter felt is an ideal filtering material in pulse cleaning dust collectors for filtering coal-fired boilers, garbage incinerators, and power plant fly ash. According to different requirements of working conditions, our company can perform various functional treatments on PPS needle punched felt, such as water and oil repellent, PTFE impregnation, coating, film covering, etc.<\/p>\n Air permeability (L\/\u33a1\/S)<\/p>\n (m3\/m2\/min)<\/p>\n<\/td>\n 150<\/p>\n 18<\/p>\n<\/td>\n 200<\/p>\n 15<\/p>\n<\/td>\n 250<\/p>\n 12<\/p>\n<\/td>\n 200\uff5e300<\/p>\n 8-15<\/p>\n<\/td>\n<\/tr>\n PPS fiber has high temperature resistance, complete str…<\/p>\n","protected":false},"featured_media":367,"comment_status":"open","ping_status":"closed","template":"","meta":[],"class_list":["post-438","product","type-product","status-publish","has-post-thumbnail","product_cat-needle-punched-filter-felt","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/product\/438","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/comments?post=438"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/media\/367"}],"wp:attachment":[{"href":"http:\/\/weiruifu.tz128.com\/index.php\/wp-json\/wp\/v2\/media?parent=438"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
2. Suitable for situations with an oxygen content of 15% or less.
3. The sulfur-containing oxides in fuel or flue gas have been proven to be fibers with strong resistance to acid and alkali corrosion and chemical resistance.
4. In situations where there is moisture in the flue.
5. Under industrial and mining conditions with temperatures ranging from 190 \u2103 to 232 \u2103, PPS filter bags have excellent performance records when used for online cleaning with an air to cloth ratio of up to 5:1 and offline cleaning with an air to cloth ratio of 6:1.<\/p>\n\n\n
