Product Description
Deinking agent at room temperature
Product structure and performance
The deinking agent at room temperature, using state-of-the-art development and production of transgenic technology. A new product designed for washing and flotation deinking. High temperature, acid and alkali, high activity, the amount is small, fast response, short duration of action, small ink granule, washing ability, good deinking effect. Can be used directly added without the need to change the current process and increase equipment investment, simple and easy to use.
Second, the technical parameters
The appearance of brown liquid evaporation rate and water
Proportion of 1.0-1.1 Vapor Pressure (20 ° C) with water
Water-soluble soluble boiling point (0 ℃, 780mmHG) 100-105
Third, the range of applications
For office paper, newsprint, magazine paper, books, paper and waste paper deinking flotation washing.
Fourth, the use of process conditions
Add points pulper deinking dosage (%) 0.1-0.2
Applicable PH 9-10 the alkali dosage (%) 1-2
Reaction time (min) 20-30 applicable temperature (° C) at room temperature
Use (as an example to deinking one ton of old newsprint)
1. Weighed 1-2 kg of deinking agents, caustic soda (96%) of 15-20 kg, 15-20 kg of sodium silicate, hydrogen peroxide, 30 kg of waste paper one ton spare.
2. In Hydrapulper into the clear water, and put into deinking agent, caustic soda, starting the pulper, the mix of drugs.
3. Boot put into waste paper, keep pulping 20-30 minutes, the pulping time must be increased the Frothing ineffective pulper, ensure mixed and pulping effect.
4. To ensure that the deinked pulp have a certain degree of whiteness, in the de-inking is completed in 3-5 times in the pulper to add hydrogen peroxide, bleaching.
5. Detection deinking quality, to achieve complete removal of ink particles can put the pulp into the washing and flotation process.
Effect analysis
With this product without changing the original de-inking equipment and technology, just off the ink no longer warm, at room temperature to complete the de-inking process, save a lot of heat, so that the de-inking lower cost, significant economic benefits. The deinking agent price quite ordinary deinking agent, the amount of more provinces, especially the protection of the fiber strength, increase pulp yield is unmatched by ordinary deinking agent.
Seven, packaging, storage and transportation
25kg plastic drum. Transport without special requirements. Below 40 ℃ under non-refrigerated conditions, the storage time for one year. Difficult to burn, do not pollute.
8 Note: comply with routine operating procedures should be used to avoid the pollution of the environment.
