Introduction of liquid polypropylene pp filter bag

Type #1 #2 #3 #4 #5 liquid polypropylene pp filter bags are used for the following industries;

Sewage, chemical, ceramic and pharmaceutical etc.

Polypropylene PP filter bag is made of polypropylene non-woven fabric. Polypropylene filter is processed by fiber needling (divided into short fiber, filament and mono-filament).

Different types of procedure requirements can produce filter cloth with different precision. Its internal honeycomb structure can effectively filter particles and suspended impurities in liquid solution. It is the best choice for high acid value filter products.

The PP filter bag is made by needling. The fiber structure is loose and the impurity carrying space is increased. It belongs to the compound interception mode. Its internal honeycomb structure effectively removes solid and soft particles as the larger particle impurities are trapped on the fiber surface, while the fine particles are trapped in the deep layer of the filter material. It will not be damaged due to the increase of pressure during use and has high filtration efficiency.

In addition, the outer surface of the product receives high-temperature surface heat treatment of instant singeing technology and calendaring treatment to effectively prevent the fiber from being lost by the high-speed impact of liquid during filtration. This ensures that no fiber is separated and avoid the excessive blockage of filter holes caused by traditional rolling treatment and shorten the life of filter bags. At the same time the pressure difference is small and does not affect the flow rate.

Reasons for Liquid polypropylene pp filter bag

1. PP filter bag is non-toxic and tasteless which can be used in food processing industry.

2. The filtering accuracy of the filter bag is continuously improved which can be applied to a wide range of filtration solutions. It has an excellent accuracy of 0.1-800 microns.

3. It can bear greater working pressure with small pressure loss .Thereby having low operating cost and obvious energy saving effect.

4. Large filtration capacity with small volume and large contaminant capacity.

5. It is convenient and fast to replace the filter bag and the filter is free of cleaning hereby saving labor and time.

6. The filter bag can be reused after cleaning to save cost.

7. It can be widely used in the following industries:

Urban sewage treatment, copper powder recovery, gold recovery, chemical industry, petroleum, bioengineering, pharmacy, electronics, electroplating, industrial wastewater, seawater desalination, printing and dyeing, paper making etc.

Structure type: thread sewing & fully welding

Fully welded liquid filter bags;

Fully-welded construction for high efficiency and bypass-free filtration

• Fully-welded construction with Sffiltech filter bag seal ring provides 100% bypass-free filtration

• The pressure-activated Sffiltech filter seal ring provides a flexible and chemically resistant seal which adapts to any bag filter housing

• Material is free from silicone and crater-forming substances

• Special heat set and polish surface treatment significantly reduces fiber release

• Stable and flexible welded seams that adapt to the restrainer basket

• The handles in the ring make replacing the filter bag quick and easy

• Sffiltech strongly recommends the use of an insertion tool that facilitates the insertion of the filter bag into the bag filter housing and ensures the correct alignment of the filter bag inside the restrainer basket

Competitive Advantage of liquid polypropylene pp filter bag

1. The PP in the filter bag is a non-toxic, tasteless, milky white, highly crystalline polymer which is one of the lightest varieties of all plastics presently. It is particularly stable to water and has water absorption of only 0.01% per 14h . The molecular weight is about 80000 ~ 150000, with good formability and good surface gloss.

2. PP material of the filter bag has high crystallinity and regular structure, so it has excellent mechanical properties. It’s strength, hardness and elasticity are higher than those of high-density PE.

The outstanding feature is the resistance to bending fatigue (7 × 10 ^ 7) times of opening and closing are folded and bent without damage marks. The dry friction co-efficient is similar to that of nylon, but not as good as that of nylon under oil lubrication.

3.PP has good heat resistance with a melting point of 164 ~ 170 ℃ . The product can be sterilized at a temperature above 100 ℃. It does not deform at 150 ℃ without external force .

Embrittlement is - 35 ℃ and will occur below - 35 ℃, but the heat resistance is not as good as PE. However, the liquid polypropylene pp filter bag is a good temperature resistant.

4. Liquid polypropylene pp filter bag has good chemical stability. In addition to being eroded by concentrated sulfuric acid and concentrated nitric acid. It is relatively stable to other chemical reagents and has good anti-corrosion effect. However, low molecular weight aliphatic hydrocarbons and aromatic hydrocarbons can soften and swell PP.

5. Polypropylene material of Liquid polypropylene pp filter bag has excellent high-frequency insulation performance. Because it hardly absorbs water so it’s insulation performance is not affected by humidity and has a high dielectric co-efficient.
