簡介 INTRODUCTION

粉末燒結過濾材料(包括管式和板式)是以金屬粉末為原料，朝篩' 成型，燒結而成的微過濾元件。 過濾精度高，透氣阻子，機械強度高，材料利用率高，適宜較高的工作熊和耐熱沖擊。廣泛用于醫 藥工業、水處理工業、食品工業、生物工程、化學工業、石油化工、冶金工業及氣體凈化領域。因而 粉末燒結過濾材料以其高科技材料組成和特殊成型工藝，使題有獨有的優良性能，是一種具有廣泛 發展前景的新型過濾材料。

Powder sintered filter material (including tube type and plate type) is made of metal powder as raw material, through sieve, molding, sintering and into the micro filter element. The filter has high filtering precision, good air permeability, high mechanical strength, high material utilization rate, and is suitable for high working temperature and heat shock resistance. Widely used in pharmaceutical industry, water treatment industry, food industry, biological engineering, chemical industry, petroleum and chemical industry, metallurgy industry and gas purification field. Therefore, the powder sintered filter material is made of high technology materials and special forming process, so that it has excellent properties and is a new type of filter material with wide development prospect.

特性 CHARACTERSTICS

?耐高溫，在500攝氏度以下正常使用。

-過濾精度高，孔隙穩定，能有效去除懸浮物和微粒等，過濾精度優異，凈化效果好。

-透氣性好，壓力損耗小。孔隙率高，孔徑均勻，初始阻力小，易于反吹，可在線再生，易清洗，再生 能力強，使用壽命長。
