濾布與濾芯的差異解析 Filter Cloth vs. Filter Cartridges: Key Differences in Industrial Filtration
在工業過濾領域中，「濾布」（Filter Cloth）與「濾芯」（Filter Cartridge）是兩種最常見的過濾介質。
In the field of industrial filtration, “Filter Cloth” and “Filter Cartridges” are two of the most commonly used filtration media.
它們雖然同屬於固液分離技術，但應用場景、結構設計與性能表現卻存在顯著差異。
Although both belong to solid-liquid separation technologies, they differ significantly in application scenarios, structural design, and performance.
什麼是濾布？
What is Filter Cloth?
濾布是一種由聚丙烯（PP）、聚酯（PET）、尼龍（PA）等纖維織造而成的過濾材料，廣泛應用於壓濾機、真空陶瓷壓濾機等設備。
Filter cloth is a woven material made from fibers such as polypropylene (PP), polyester (PET), or nylon (PA), widely used in filter presses and vacuum ceramic filters.
它主要依靠纖維間的孔隙來攔截懸浮顆粒，並形成可脫落的濾餅。
It primarily relies on the pores between fibers to trap suspended solids and form a detachable filter cake.
什麼是濾芯？
What is a Filter Cartridge?
濾芯通常為圓柱狀結構，由摺疊式或熔噴纖維組成，安裝於壓力容器或過濾殼體內，用於精密過濾。
A filter cartridge usually has a cylindrical structure, made of pleated or melt-blown fibers, and is installed in pressure vessels or filter housings for precision filtration.
濾芯能有效過濾細小顆粒與雜質，適用於高純度要求的工業場合，例如製藥、食品飲料與電子行業。
Filter cartridges effectively capture fine particles and impurities, making them ideal for high-purity industries such as pharmaceuticals, food & beverage, and electronics.
濾布與濾芯的主要差異
Main Differences Between Filter Cloth and Filter Cartridges
| 項目 Aspect | 濾布 Filter Cloth | 濾芯 Filter Cartridge |
|---|---|---|
| 應用設備 Applications | 壓濾機、真空陶瓷壓濾機 Filter press, vacuum ceramic filter | 過濾器殼體、精密過濾裝置 Filter housings, precision filtration systems |
| 過濾精度 Filtration Accuracy | 一般為 1–50 微米 Typically 1–50 microns | 可達 0.1 微米甚至更低 As fine as 0.1 micron or lower |
| 固液分離效率 Solid-Liquid Separation Efficiency | 適合高濃度漿料、形成濾餅 Suitable for high-solid slurries, cake formation | 適合低濃度懸浮液、精密去雜 Best for low-solid suspensions, fine impurity removal |
| 維護與更換 Maintenance & Replacement | 可清洗重複使用，壽命長 Washable and reusable, long lifespan | 一次性或有限次使用，需定期更換 Disposable or limited-use, requires regular replacement |
如何選擇合適的過濾介質？
How to Choose the Right Filtration Medium?
若工廠的工序產生高濃度固液混合物，例如陶瓷、石材、玻璃行業的切割與打磨廢水，濾布與壓濾機的組合是最佳選擇。
If your factory generates high-solid slurries, such as cutting and grinding wastewater from ceramics, stone, or glass, filter cloth combined with filter presses is the best solution.
若需要高純度液體，或應用於製藥、食品飲料生產，則應使用濾芯過濾系統，以確保水質或液體純度。
If you require high-purity liquids, or operate in pharmaceuticals or food & beverage production, filter cartridge systems should be used to ensure purity.
