Embodiment

[0022] The anti-corrosion self-lubricating screen cloth of the oilfield mud shale shaker is made of corrosion-resistant self-lubricating paint on the stainless steel mesh cloth. The corrosion-resistant self-lubricating paint is composed of α-crystalline composite alumina and nano-composite ceramic slurry at a ratio of 1.5:1. than mixed.

[0023] Nano-composite ceramic slurry is prepared from nano-carbon black with a mass fraction of 3.5%, 17.5% nano-ceramic powder and 89% absolute ethanol, and nano-carbon black is added to absolute ethanol to make a single-phase nano-carbon black suspension , and then adding nano-ceramic powder into absolute ethanol to make a single-phase nano-ceramic suspension, mixing the two parts of the suspension and ball milling for 8 hours.

[0024] The production steps of anti-corrosion self-lubricating screen cloth for oilfield mud shale shaker are as follows:

[0025] (1) Degrease, degrease and decontaminate the finished stainless steel mesh cloth, ...

Abstract

The invention discloses anticorrosion self-lubricating bolting cloth of an oil field mud vibrating screen and a manufacturing method thereof. The anticorrosion self-lubricating bolting cloth is made by coating stainless steel screen cloth with anticorrosion self-lubricating coating, and the anticorrosion self-lubricating coating is formed by mixing alpha-crystal form composite aluminum oxide and nano-composite ceramic slurry according to a mass ratio. The nano-composite ceramic slurry is prepared from nano carbon black, nano ceramic powder and absolute ethyl alcohol according to a mass ratio; finished bolting cloth is naturally dried after being deoiled, degreased and descaled, and the dried screen cloth is subjected to spraying, brush coating and dip coating so that a coating can be completely attached to the screen cloth; the screen cloth coated with the coating is placed into a non-pollution drying room for continuous constant temperature drying, and then placed into the natural environment for natural ceramization; and the vibrating bolting cloth of the standard specification is directly manufactured. The bolting cloth is high in abrasion resistance, surface hardness and hydrophobicity, free of water and resistant to acid, alkali and corrosion, and the service life of the bolting cloth is prolonged by 50% or above.

Description

technical field [0001] The invention relates to the field of oil field equipment, in particular to an anti-corrosion self-lubricating screen cloth of an oil field mud vibrating screen and a manufacturing method thereof. Background technique [0002] The existing oil well shale shaker is a high-frequency sieving mechanical equipment, which sieves drilling cuttings and then classifies and disposes of pollutants and wastes. The sieve cloth is the core part of the sub-sieve, which mainly classifies different types of stones, sand, chemical reagents, water, etc. The screen cloth is ordinary stainless steel mesh cloth without anti-corrosion and self-lubricating treatment. It is easily corroded by alkaline drilling fluid during use. The pumped mud directly acts on the screen cloth with a certain pressure. In addition, the gravel has sharp edges and corners. Once the screen cloth is corroded Afterwards, it is easy to be directly penetrated by the gravel, and the large-grain debris ...
