Description
Alkali lignin ********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: ****2
Moisture: 5.0%max
lignosulphonate: *0%min
Total reducing matter: 4.0% max
2.Main Specification1,Can reduce *0% of water consumption at least
;2, can improve mixture of the concrete;3, Compression strength
improves by more than *5% equally on ***8 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.**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;
