It has been widely used in petroleum engineering, paper making and the environmental protection, become a very important material and additives in many industrial sector. During a series of contrast experiments, it’s come to the conclusion that BLS has a certain degree of anti-temperature performance, salt-resistant properties and acid-fast performance, the specific circumstances are followed:(1)At room temperature, viscosity of the solution which contains 0.8% BLS thickener can reach 63.5mPa?s, so BLS has a good thicken capacity;(2)At 80℃, viscosity of the solution which contains 0.8% BLS thickener can reach 26.0mPa?s, so BLS has a certain degree of anti-temperature performance;(3)At 80℃, viscosity of the solution which contains 0.8% BLS thickener and 6.0% Sodium chloride can reach 22.0mPa?s, so BLS has a good salt-resistant properties;(4)At 80℃, viscosity of the solution which contains 0.8% BLS thickener and 3.0% Calcium chloride can reach 23.5mPa?s, so BLS has a certain degree of calcium-resistant properties;(5)At 70℃, viscosity of the solution which contains 0.8% BLS thickener and 13.0% Hydrochloride can reach 22.5mPa?s, so BLS has a certain degree of acid thickening;(6)At 70℃, viscos
