| 应用领域 | Uses: Used to maintain viscosity in hydraulic fracturing fluids、[HSDB]、Petroleum Production and Refining [Category: Industry]、Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base、which includes alcohol-water mixtures and low strength acids、make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development、crosslinkers for viscosity enhancement、pH control chemicals、gel breakers for polymer degradation following the treatment、clay stabilizers、alcohol、bactericides、fluid loss additives and friction reducer.、Hydraulic fracturing、Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow、increasing resource production. ... Chemical Name: Potassium metaborate、Chemical Purpose: Maintains fluid viscosity as temperature increases、Product Function: Crosslinker.、Industry Uses: Corrosion inhibitor、Cleaning agent、Processing aids、specific to petroleum production、Processing aids not otherwise specified、U.S. Production: 2023: 100、000 - <250、000 lb、2022: 250、000 - <400、2021: 250、2020: 100、Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: Boric acid、potassium salt. Aggregated National Production Volume: 1 to < 10 million pounds.、General Manufacturing Information: Petroleum Refineries、Fabricated Metal Product Manufacturing、Oil and Gas Drilling、Extraction、and Support activities、Boric acid (HBO2)、potassium salt (1:1): ACTIVE |
