The sharp rise and fall of papermaking has long been the norm in the papermaking industry. On the one hand, it is based on the demand of the market, on the other hand, the more critical issue is the cost. Blistering is a typical example, and it brings a series of troubles that directly affect the process of paper production and processing, thus increasing the cost burden. To solve this problem, the use of paper-making defoamers is perfect.
We all know that there are two reasons for the increase in the cost of papermaking, the price increase of raw materials in the market, and the extra budget due to improper production and processing. Of course, the price increase is out of our control as stipulated by the market, so it is reasonable and practical to find the reason from ourselves. Let’s take a look at the hazards of excessive foam in paper production and processing:
1. Too much foam will affect the degree of bonding between papers during papermaking, which will directly lead to a great reduction in the quality of paper
2. Foam will cause high air bubble content in the slurry, which will not only affect the dehydration of the wire part, cause paper defects, reduce machine speed, and cause paper breakage, but also easily reduce the operating efficiency of the pump and increase energy consumption
3. Too much foam will make the entire flow delivery system unstable, and even cause tripping and shutdown of the sizing pump, which will reduce papermaking efficiency and increase papermaking costs
The paper defoamer is specially designed for the foam in the papermaking process in the papermaking industry. The foam problem of the product must be solved during the papermaking process, otherwise it will seriously affect the stability of production and the quality of paper. So what is the reason for choosing a paper-making defoamer, and what advantages does it have to deal with the paper-making foaming problem?
1. Strong defoaming power, long-term foam suppression, less dosage, no worry about affecting the performance of the foaming system
2. Good dispersion performance, no uneven surface defects such as fish eyes and shrinkage cavities
3. It is composed of high-efficiency defoaming ingredients such as high-fatty alcohol and polyether, does not contain silicon, and will not appear silicon spots
4. Add before and after foam generation to achieve the effect of foam suppression and defoaming respectively. According to different systems, the amount of addition is 0.1%~0.3% of the total system, and the specific test shall prevail
5. It can be used directly or after dilution, but please pay attention to the dilution method according to the manufacturer's method, so as to avoid delamination and demulsification, which will affect the product quality.
