【Polypropylene liquid filter bag】

Polypropylene (PP) polypropylene has good wearability and high resilience. It is an excellent thermoplastic fiber. Polypropylene felt is often used in low-temperature pulsed filter bag and chemical and pharmaceutical plant pulse bag. Under the operating temperature of 130 C, the heat resistance is less than polyester. But polypropylene fiber has good chemical stability. Besides being corroded by concentrated sulfuric acid and concentrated nitric acid, it is stable for all kinds of chemical reagents and has good anticorrosive effect. But the low molecular weight of fatty hydrocarbons and aromatic hydrocarbons can soften and expand the PP. The filtering precision is in the range of 1-200um.

Product application

Food and beverage; bioengineering and medicine; petrochemical and chemical industry; automobile manufacturing; oil and gas; electronic and electroplating; paint, paint, ink; nuclear and thermal power and waste water filtration; photographic film production process of liquid liquid and gas filtration; daily chemical purification; mechanical processing and refrigeration industry all kinds of cooling liquid filtering; all kinds of textile, printing and dyeing, papermaking industry liquid purification.

Ring material

The ring mouth can have stainless steel ring mouth, PP ring mouth and PE plastic ring mouth, including a variety of different bag bottom, bag top design.

Production process:

1. hot-melt: using the most advanced ultrasonic welding, hot-melt welding to ensure that the filter bag has the best bonding strength, to prevent leakage.
2. seam: my company's filter bag sewing is very strict, five line edging, firm and durable, the car joint sealing effect into full play. The pure car sewing thread does not contain any lubricant ingredients such as silicone oil, which evade the two pollution problems of the ordinary seams filter bag.

Filter precision, micron (m) level:
1、5、10、25、50、75、100、150、200
