Description :

　　Yangmufang, a commonly used wood in the north of Shuyang County's Xingxing Wood Processing Factory, has fine and soft texture, stable properties, and is inexpensive and easy to obtain. Often used as an accessory for elm furniture and as a base material for lacquer furniture in ancient furniture. This is the so-called poplar, also known as "small leaf poplar", which often has a humorous luster, so it is also called "satin poplar", not the kind of Soviet poplar, big leaf poplar, Populus euphratica introduced in the mid-20th century. Yangmu often has a "pungent smell" and is lighter and softer than birch. Birch wood has a slight fragrance and often has very fine brownish black water soaked lines. This is the difference between the two.

　　Pre treatment of high yield chemical pulp with DTPA before lignin removal using poplar NS-AQ method

　　High yield chemical pulp delignification with DTPA pretreatment using poplar NS-AQ method - The results show that DTPA pretreatment has a certain impact on pulp properties. Within the pH range of 1, as the pH increases, the whiteness of the pulp decreases. The suitable conditions for DTPA pretreatment are: pH: 3, time: 30 minutes, temperature: 40~C, slurry concentration: 15%, dosage: 2.5%. Pre treatment improves the selectivity of oxygen delignification reaction, reduces kappa number by 12%, increases viscosity by 4.7%, and increases whiteness by 5.4%
