In the pulp and paper industry, environmentally friendly and efficient additives are the key to improving production quality. Yuanlian Chemical's green chelating agents, including tetrasodium glutamate diacetate (GLDA-Na), methylglycine diacetate trisodium (MGDA-Na), Tetrasodium Aspartate Diacetate (ASDA-Na) and imino disuccinate tetrasodium (IDS-Na), with their biodegradable properties, have become an ideal substitute for traditional EDTA and DTPA, and play an important role in the pulp and paper industry.

Pulping hydrogen peroxide bleaching stabilizer

This type of chelating agent for pulping has a strong ability to capture and disperse metal ions. It can chelate with polyvalent metal ions such as calcium, magnesium, zinc, and iron in a wide pH range to form more stable water-soluble complexes. This property can effectively avoid the problems of precipitation and scaling caused by metal ions during the bleaching process, failure decomposition of bleach agent, and yellowing of pulp. At the same time, it can also protect the pulp fibers and improve the dispersion of bleach.

its advantages are significant: First, it can effectively inhibit the catalytic decomposition of metal ions on hydrogen peroxide, hypochlorous acid and other bleaching agents, improve bleaching efficiency, save the amount of bleaching liquid, and reduce the cost of bleaching; Second, it has a strong capture and dispersion ability for Fe ions, which can prevent it from reacting with phenol groups in the pulp to form dark compounds, protect fibers, improve pulp whiteness, and reduce pulp yellowing; Third, it can prevent metal ions such as calcium and magnesium from chemically reacting in the pulp bleaching process to form deposits, thereby preventing system equipment and pipeline scaling, and can gradually remove the original scaling of the rinsing system; Fourth, it has a certain dispersion ability, which can improve the dispersion of sodium silicate; Fifth, it can protect pulp fibers and avoid damage to fibers due to the peeling reaction of NaOH; Sixth, it can be used with Compared with traditional DTPA, this kind of green degradable chelating agent has better environmental performance.

Papermaking Auxiliary

In the production of household paper, the wrinkling process is a common way to make paper soft, and the wrinkling agent is the core of the process, which is mainly composed of two parts: adhesive and peeling agent. The function of the adhesive is to make the wet paper web reach the surface of the Yanke dryer and adhere to its surface. During the wrinkling process, if the viscosity or rewettability of the adhesive is insufficient, it will often lead to paper tearing, paper jams, uneven wrinkling, etc., and yellow edges will appear on both sides of the surface of the dryer. The green chelating agent of Yuanlian Chemical is applied to the crescent paper machine, which can be made into an adhesive by the wrinkling control process of soft tissue paper. For conventional paper machines, it can show excellent cylinder sticking performance. Spraying it on the Yankee dryer provides an excellent dryer protection base coating and adhesion properties, which helps the paper sheet to adhere tightly to the surface of the dryer, and the formed soft coating can ensure the smooth operation of the wrinkle scraper, avoiding the accumulation of hard coatings and the resulting vibration traces. Yuanlian Chemical's green chelating agent brings environmentally friendly and efficient solutions to the pulp and paper industry, helping the industry achieve high quality and sustainable development.
