用于過(guò)濾器常用的主要過(guò)濾材料大致有以下幾種：
The main filter materials commonly used in filters are as follows:
1、混合纖維素酯
1. Mixed cellulose esters
常用來(lái)制成圓形的單片平板濾膜，用于液體和氣體的精過(guò)濾；
It is often used to make circular monolithic flat filter membrane for fine filtration of liquids and gases.
2、聚丙烯
2. Polypropylene
做成折疊式，常用于筒式過(guò)濾器，有較大的孔徑，其具有親水性，屬粗過(guò)濾材料；
Made of folding type, often used in cylindrical filters, with larger aperture, hydrophilic, belonging to the coarse filter material;
3、聚偏二氟乙烯
3. Polyvinylidene Difluoride
屬精過(guò)濾材料，耐熱和耐化學(xué)穩(wěn)定，蒸汽滅菌承受性良好，可制成親水性濾膜，較廣泛應(yīng)用于制藥工業(yè)無(wú)菌制劑用水及注射用水的過(guò)濾；
It is a fine filtration material with heat and chemical stability, good steam sterilization tolerance, and can be made into hydrophilic membrane. It is widely used in the filtration of sterile preparation water and injection water in pharmaceutical industry.
4、聚醚砜
4. PES
做成折疊式，常用于筒式過(guò)濾器，耐溫耐水解性能好，親水性材料，用于精度較高的溶液的精過(guò)濾；
It is made into folding type and is often used in cylindrical filter. It has good temperature resistance, hydrolysis resistance and hydrophilic material. It is used for fine filtration of solution with high precision.
5、尼龍
5. Nylon
做成折疊式，常用于筒式過(guò)濾器，親水性材料，常用作液體的精過(guò)濾；
Made into folding type, often used in cylindrical filter, hydrophilic material, often used for liquid fine filtration;
6、聚四氟乙烯
6. Polytetrafluoroethylene
做成折疊式，常用于筒式過(guò)濾器，疏水性材料，其是使用相當(dāng)廣泛的一種材料，耐熱耐化學(xué)穩(wěn)定，常用于水、無(wú)機(jī)溶劑及空氣的精過(guò)濾。
Made of foldable, often used in cylindrical filters, hydrophobic materials, it is a widely used material, heat-resistant and chemical stability, often used in water, inorganic solvents and air fine filtration.
另外，過(guò)濾材料按與水的關(guān)系分為親水性（水可浸潤(rùn)的）和疏水性（水不浸潤(rùn)）兩種。
In addition, filter materials can be divided into hydrophilic (water can be infiltrated) and hydrophobic (water does not infiltrate) according to the relationship with water.
親水性的過(guò)濾材料主要應(yīng)用在水或水/有機(jī)溶液混合的過(guò)濾和除菌過(guò)濾；疏水性過(guò)濾材料是通過(guò)水被截流或“引導(dǎo)”進(jìn)入濾膜，主要應(yīng)用在溶劑、酸、堿和化學(xué)品過(guò)濾，罐/設(shè)備呼吸器,工藝用氣,發(fā)酵進(jìn)氣/排氣過(guò)濾。
Hydrophilic filter materials are mainly used in water or water/organic solution mixtures for filtration and bactericidal filtration; hydrophobic filter materials are mainly used in solvent, acid, alkali and chemical filtration, tank/equipment respirator, process gas, fermentation intake/exhaust filtration through water interception or "guide" into the filter membrane.
