What are the lining of electromagnetic flowmeter? This is the point that we must consider when purchasing the instrument, because it directly affects the price and service life of electromagnetic flowmeter. Let's learn about the lining of electromagnetic flowmeter together!

各类电磁流量计内衬的优缺点

Advantages and disadvantages of lining of electromagnetic flowmeter

1、普通橡胶，天然橡胶，软橡胶，硬橡胶。

1. Ordinary rubber, natural rubber, soft rubber, hard rubber.

优点：运行温度60℃，其特点就是富有弹性并且拥有不错的耐磨性能，一般用于城市供排水等领域。

Advantages: the operating temperature is 60 ℃, which is characterized by elasticity and good wear resistance. It is generally used in urban water supply and drainage fields.

缺点：耐腐蚀性就相对较差。

Disadvantages: relatively poor corrosion resistance.

2、聚四氟乙烯，也叫PTFE，也叫F4。

2. Polytetrafluoroethylene, also known as PTFE, also known as F4.

优点：比较常用的内衬材质之一，因为其化学性质稳定，所以一般用于卫生级液体或强腐蚀液体，如浓酸浓碱等。

Advantages: one of the commonly used lining materials, because of its stable chemical properties, it is generally used for sanitary liquid or strong corrosive liquid, such as concentrated acid and concentrated alkali.

3、聚全氟乙丙烯，也叫F46。

3. Perfluoroethylene propylene, also known as F46.

优点：电磁流量计此种材质与PTFE类似，但耐磨性能强于PTFE材质，同样介质温度最高可达100℃。

Advantages: this material of electromagnetic flowmeter is similar to PTFE, but its wear resistance is better than PTFE. The temperature of the same medium can reach 100 ℃.

4、聚氟合乙烯，也叫Fs。

4. Polyfluoroethylene, also known as FS.

特点：性价比高，成本较F4材质低。

Features: high cost performance, low cost compared with F4 material.

缺点：与F4材质类似的特性但承受温度稍差了一些，一般介质温度不超过80℃。

Disadvantages: similar to F4 material, but the bearing temperature is slightly worse, and the medium temperature generally does not exceed 80 ℃.

5、氯丁橡胶，也叫CR，也叫Neoprene。

5. Neoprene, also known as Cr, or neoprene.

优点：耐磨性能好，且弹性非常出色，一般用于供排水、污水处理等领域。

Advantages: good wear resistance, and excellent elasticity, generally used in water supply and drainage, sewage treatment and other fields.

缺点：耐腐蚀性能稍差，不耐氧化是它的缺点。

Disadvantages: corrosion resistance is slightly poor, oxidation resistance is its disadvantage.

6、聚氨酯橡胶，又叫Polyurethane。

6. Polyurethane rubber, also known as polyurethane.

优点：电磁流量计拥有极好的耐磨性能。

Advantages: electromagnetic flowmeter has excellent wear resistance.

缺点：腐蚀性就显得能力不足了，且温度不得超过80℃，一般用于对耐磨要求比较高的工矿环境，如矿浆煤浆等介质的测量。

Disadvantages: the ability of corrosivity is insufficient, and the temperature should not exceed 80 ℃. It is generally used for the measurement of medium such as mineral slurry, coal slurry and so on.

7、陶瓷材质

7. Ceramic material

特点：陶瓷无疑是所有材质中比较好的产品。

Features: ceramics is undoubtedly the better product of all materials.

缺点：价格不接地气，制作过程复杂，对工艺要求比较苛刻，售价也高。

Disadvantages: the price is not grounded, the production process is complex, the process requirements are more stringent, and the price is also high.
