Meishen Technology Company
As the paper
industry is affected by environmental factors, manufacturers have carried out
transformation and upgrading, change the previous production process, so
magnesium oxide in the paper industry is more and more popular with customers,
below we will have a detailed understanding of the papermaking magnesium oxide
related matters.
Magnesium
oxide was used to replace ammonia water in ammonium sulfite pulping. Magnesium
oxide is used as alkaline buffer, and the indexes of slurry can reach the level
similar to that of ammonia water method. Magnesia as a buffer, pulp is easy to
bleach, can promote the process of distillation of lignin, reduce pollutant
emissions, help to protect the environment, but also can reduce costs.
Magnesium oxide is used in pulp bleaching. Compared with the traditional
bleaching process, magnesium oxide can replace caustic soda. At the same time,
magnesium oxide can improve the viscosity of the slurry, maintain the
brightness of the pulp, and reduce the content of COD and production costs.
In
the process of hydrogen peroxide bleaching pulp, magnesium oxide can replace
caustic soda, to reduce the content of iron, manganese ions in the slurry role,
but also to avoid the presence of excess iron and yellow, improve the quality
of slurry. At the same time, magnesium oxide has a buffering effect and easy to
control the pH value.
If
combined with phosphate, silicate and other inorganic complexing agents will be
better. Magnesium oxide can be used as a wetting agent to improve pulp deinking
operations. The traditional sulfite pulping process can be improved to make
magnesium sulfite pulping process. After the improvement, wood of lower quality
can be used as raw material. The paper pulp produced can be used for news
printing paper. In this way, many ecological and economic problems in
traditional sulfite pulping operations have been solved for paper mills.
Meishen
is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide
of magnesium, an ionic compound. It is a white solid at room temperature.
Magnesium oxide exists in the form of periclase in nature and is a raw material
for magnesium smelting. Magnesium oxide is white or light yellow powder,
odorless, tasteless, this product is insoluble in water and ethanol, melting
point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory
insulation properties. It can be converted into crystal by burning at a temperature
above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or
sintered magnesia.
Magnesium
oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia
bricks, refractory materials and moisturizing materials. It is also widely used
in rubber, rubber sheet, rubber products, pharmaceutical industry, food
industry, plastic sheet accelerator, glass fiber reinforced plastics and
Surface coating of silicon steel sheet, paper production, steel ball polishing,
leather treatment, insulation materials, grease, dyes, ceramics, desiccant,
resin, flame retardant, etc.
Hebei
Meishen Chemical Technology Group is the main magnesium oxide producer in the
world. It is also the largest magnesium salt producer in China and has won the
ISO9002 quality system certification. It also has GMP-Certification.
With
rich experience in the research, development, production, management and
