[0019] Material formula (master batch):

[0020] Polypropylene: 71.5%

[0021] Polyvinylidene fluoride: 4%

[0022] Nano calcium carbonate: 3%

[0023] Glass fiber: 20%

[0024] Antioxidant (1010): 1.5% addition

[0025] The packing structure is a flat plate, which is prepared by extrusion calendering process at 180℃

[0027] Material formula (master batch):

[0028] Polypropylene: 77.5%

[0029] Polyvinylidene fluoride: 6%

[0030] Nano calcium carbonate: 5%

[0031] Glass fiber: 10%

[0032] Antioxidant (1010): 1.5% addition

[0033] The packing structure is corrugated board, which is prepared by extrusion calendering process at 180℃

[0034] Through the application of flat plates, corrugated plates and egg trays made of polypropylene modified coalescing materials to the application of coalescing oil from oily sewage at the Tuoyi Joint Station of Shengli Oil Production Plant of Shengli Oilfield, significant effects have been seen.

[0035] The experiment on coalescing and degreasing of oily sewage in the oil field was carried out at the Tuo Yi Joint Station of Shengli Oil Production Plant. The produced water of Tuoyi Station contains more polyacrylamide, so oil-water separation is more difficult. The oil-water separation device for coalescence test is 200cm long, 40cm wide, 70cm high, and its effecti...

Abstract

The invention relates to a coalescence material. The technical scheme is that: a polypropylene coalescence material is modified by polyvinylidene fluoride, nano-calcium carbonate, glass fibers and a 1010-antioxidant and the modified formula is formula a or formula b. According to the formula a, the mass part ratio of polypropylene, polyvinylidene fluoride, nano-calcium carbonate, glass fibers and 1010-antioxidant is 71.5%: 4%: 3%: 20%: 1.5%. According to the formula b, the mass part ratio of polypropylene, polyvinylidene fluoride, nano-calcium carbonate, glass fibers and 1010-antioxidant is 77.5%: 6%: 5%: 10%: 1.5%. According to the above formula a or formula b, the coalescence material is prepared by the steps of mixing the above components according the mass part ratio in the above formula a or formula b; mixing the raw materials uniformly at the temperature of between 50 and 80 DEG C; granulating the raw materials in a granulation machine; and drying at the temperature of between 50 and 95 DEG C after granulating so as to prepare a granular master batch of a polypropylene-modified coalescence material, wherein the working temperature of the granulation machine is between 165 and 185 DEG C; and the grain size is less than 3 mm. The coalescence material is better in balance between hydrophilic and lipophilic performances and is beneficial to the coalesce separation of oil droplets in the water.

Description

1. Technical Field [0001] The invention relates to a coalescence material and a preparation method, which solves the problems of low oil removal efficiency of the existing coalescence material and poor crude oil coalescence effect. 2. Background technology [0002] At present, most of the treatment processes used for degreasing oily sewage are three-stage methods, namely degreasing-coagulation sedimentation-filtration. The commonly used degreasing method is a two-stage degreasing method, that is, one-stage gravity degreasing and two-stage coagulation degreasing. The suspended solids in the water can be removed at the same time as coagulation, or through a filtration process. At present, most countries and enterprises in the world still tend to adopt physical methods for the treatment of oily sewage. Compared with other treatment methods, coalescing oil removal has the advantages of simple process, small area, high treatment efficiency, and low cost. The oil removal process does ...
