Neenah Gessner GmbH reported a high precision Fuel Water Separator Composite Paper manufacture methods,the composite structure is designed to be spun bonded nonwoven fabric, melt blown nonwovens and wood pulp paper. Including optimization PBT melt blown nonwovens.
Purolator Filters NA LLC also reported a high precision, high life composite liquid filter, which also uses PBT.PBT is a crystalline thermoplastic polyester, melting point 225 ℃, has fast crystallization rate, heat resistance, oil resistance, chemical corrosion resistance of prominent characteristics, initially reported for modification of blood filtration.
At present, the mainstream products in the market are manufactured by European and American manufacturers, such as Neenah Gessner GmbH, Ahlstrom, H&V, etc.The product is divided into two layers and three layers, the two layers are the direct melt and wood pulp paper.Three-layer composite is protected by a spun-bonded layer above the spray layer.because of melt blown nonwoven fiber bonding force between the layers is relatively poor, spun bonded layers can prevent the spray layer destroyed in the process of transportation, processing and use.The viscose layer of the composite filter material is mainly protective, and it will also increase accommodate the dust . The melt layer is to separate the oil and water, increase accommodate the dust and improve the filtration precision.Wood pulp paper support, meet the physical performance index and pleating requirements, also determine the final filtering precision.
High precision Fuel Water Separator Composite Paper is divided into ultrasonic spot welding compound, adhesive compound or both.
Our pruduct such as FS1006, PL420 etc is High quality Fuel Water Separator, uses this high precision Fuel Water Separator Composite Paper to achieve good efficiency.
