The Ultimate Guide: Choosing the Right Filter Cloth
终极指南：选择正确的滤布

The Filter Cloth is the most critical consumable in your dewatering system. It is the only barrier between “sludge” and “clean water”.
滤布是您脱水系统中最关键的易耗品。它是“污泥”和“清水”之间的唯一屏障。

Many factory owners make the mistake of buying the cheapest cloth available. This leads to frequent clogging, tearing, and poor filtration results. At Porvoo, we help you match the cloth to your specific sludge.
许多工厂老板犯了购买最便宜滤布的错误。这导致频繁堵塞、撕裂和糟糕的过滤效果。在波尔沃，我们帮助您将滤布与您的特定污泥相匹配。

1. Material Matters: PP vs. PET vs. Nylon
材质很重要：PP vs. PET vs. 尼龙

• Polypropylene (PP / 丙纶):
  Best for: Ceramic, Chemical, and Mining industries.
  Pros: Excellent acid and alkali resistance (pH 1-14). Smooth surface for easy cake release.
  适用：陶瓷、化工和矿山行业。优点：优异的耐酸碱性。表面光滑，易于卸饼。
• Polyester (PET / 涤纶):
  Best for: Stone processing, High-temperature filtration.
  Pros: High strength, good heat resistance (up to 120°C).
  适用：石材加工，高温过滤。优点：强度高，耐热性好（高达 120°C）。
• Nylon (PA / 锦纶):
  Best for: Abrasive sludge (Mining).
  Pros: Extremely durable and abrasion-resistant.
  适用：磨损性污泥（矿山）。优点：极其耐用且耐磨。

2. Weave Type: Multifilament vs. Monofilament
编织类型：复丝 vs. 单丝

• Multifilament (复丝): Like cotton. Catches very fine particles but can clog easily if not washed.
  像棉花一样。能捕捉极细颗粒，但如果不清洗容易堵塞。
• Monofilament (单丝): Like fishing line. Excellent water permeability and the cake drops off automatically. Great for sticky sludge (like Quartz/Resin).
  像鱼线一样。透水性极佳，滤饼自动脱落。非常适合粘性污泥（如石英石/树脂）。

3. Common Signs You Using the Wrong Cloth
使用错误滤布的常见迹象

• Cloudy Filtrate: The pore size is too big. You need a tighter weave.
  滤液浑浊：孔径太大。您需要更紧密的编织。
• Wet Cakes: The cloth is clogged (blinded). You need a monofilament cloth or better washing.
  湿滤饼：滤布堵塞。您需要单丝滤布或更好的清洗。
• Frequent Tearing: The material cannot handle the chemical acidity/alkalinity.
  频繁撕裂：材料无法承受化学酸碱度。
