Paper defoamer - choice of defoamer for paper making / paper machine
The demand for defoamers in the paper industry is mainly divided into the pulp cooking stage and the paper copying stage. The different working environment of these two stages requires completely different types of defoamer. Shenyang Rise Surface Technologies Co., Ltd. in view of many years of experience in the paper industry, summed up the appropriate defoamer selection, but also to reduce the cost of paper industry customers to enhance the quality of a substantial improvement.
This article starts with a recommendation for the right defoamer product from the paper copying process stage.
Why use defoamer?
Paper copying section, due to the pulp process from a total of lignin, fatty acids, resin acid soap, deinking agents and other natural and artificially added foaming surfactants, synthetic polymers, etc., to prevent the fiber components and microfiber bonding, the paper quality has a serious impact, such as poor sizing effect, poor uniformity of quantitative width, paper surface spots or translucent spots, and even cause paper breakage.
One of the recommended products
RISE defoamer products AF2200 in a number of domestic and foreign paper mills after the application of the best results, the defoamer and the water medium tension is low, high spreading coefficient. Defoaming speed is fast, and the lasting power of foam inhibition is strong.
| Model | AF-2200 |
| Appearance | Transparent |
| Additive amount | 0.2-0.8kg/ton paper |
| Features | easy dispersion, high temperature resistance, excellent antifoaming |
| Storage temperature | 0-50℃ |
AF-2200 product advantages
①Fast defoaming, avoiding the formation of holes, reducing paper breakage and avoiding the overflow of pulp storage tank.
②Low dosage of defoamer, easy to use, no side effects, no emulsion breaking and oil bleaching.
③Improve the speed of paper machine and enhance the strength of paper width.
④Improve the one-way retention rate of filler, reduce the filler content in white water and lower the cost.
⑤Reduce the concentration and ash content of pulp web, and extend the life of forming web.
⑥Ensures the loss of fibers and wet-end chemicals, improves the smoothness and opacity of the paper sheet, the paper has a better uniformity, and greatly improves paper quality.
Usage:
Can be added directly to the system to be defoamed using a dosing pump, generally in order to control the amount added, you can add water to the paper defoamer mixed dilution after use.
Paper copying process needs to add defoamer before paper, that is, before the net, you can add the paper defoamer in the high box or white pool, such as these two positions are not convenient to add, you can add the paper defoamer in the pulp pool. It is recommended to add 200-500g of defoamer for every 1 ton of paper produced.
