Product description: Alkali lignin 8068-05-1 Alkali lignin is A type of lignin produced by treating the black liquor from the soda process with acid; used as an extender in the negative plates of storage batteries, in asphalt, and in paperboard products. Alkali lignin is one of lignosulphonate series, which can be widely used in construction, ceramic, carbon black etc.. areas. The spec. are as below: Appearance: Brown powder PH Value: 10-12 Moisture: 5.0%max lignosulphonate: 50%min Total reducing matter: 4.0% max 2.Main Specification1,Can reduce 10% of water consumption at least ;2, can improve mixture of the concrete;3, Compression strength improves by more than 15% equally on 3-28 days;4, Can reduce the initial stage of the cement heat of hydration by a large margin;5, Have no function of corroding on the reinforcing bar.4.operation methods :1. 0.2-0.5% of mixing amount in concrete (with cement weight), users can adjust the mixing amount through the test ;2. Can use after mixed liquid , also can put with cement , aggregate into mixer to use at the same time too, need lengthen time properly;3. the result is more obvious after mixing with high-efficient naphthalene department water-reducing agent. User can determine the suitable dosage according to the result that cement variety, aggregate situation, naphthalene department type of water-reducing agent are tested fixing;
