De-inking Agent SM-TM-45

De-inking agent SM-TM-45

Feature：

1. Resisted for strong alkali，anti-oxidant；

2. Excellent wetting & emulsification property；

3.The dosage is less 50% then normal de-inking agent.

Technological process：

1,Hydraulicpulper deinking method
(1)  Preparing deinking agent 0.5%,sodium silicate (silicate of soda) 3%,sodium hydroxide 3%, then put these chemical into hydraulicpulper and add warm water(water temperature 800-1000) .Start hydraulic pulper about 3 minutes, then put the wastepaper into it.
(2)   In order to reach the best effect, pulp concentration required 14%-16%(put 140KG-160KG wastepaper into pulper of a ton  volume) ,starting the pulper about 25-35minutes, then stop the pulper and keeping temperature about 10-20 minutes. 
(3)  Concentration and washing should be done immediately after blowing in order to prevent ink redeposited on the fibers.(It will get a good effect if put a spot of deinking agent when water washing)
 

2,The steam-ball deinking method
(1)  Put the following chemicals into the ball in the proportion of 6 KG of paper deinking agent, 20 KG of sodium hydroxide, and 30 KG of sodium silicate. After it is evenly mixed, and then input the water and waste paper at a solid content of 30% to 50%.
(2)  Open steam and make the temperatures to reach 800-1000 and keep 30-40 minutes, then blowing out when the pressure reaches a peak.
(3)  After blowing out, pulping first then washing . The original deinking wastewater can be reused after precipitation and impurity removal.
