soda pulping technical

First manufacture of pulp from wood, using the soda process (England)

It is made in great quantities in the soda process, by the action of sulphuric acid on common salt.

It is manufactured in large quantities as an intermediate step in the "soda process," and also for use in glass making.

AMS is used as a catalyst in production of alkaline pulping in the soda process.

Sodium carbonate is used in softening of water by lime soda process, due to this some sodium carbonate maybe left behind in the water.

In the soda process, invented by M. Meliner in France in 1865, the chips from spruce and poplar logs are boiled under pressure in a strong solution of caustic soda.

The soda process gives pulp with lower tear strength than other chemical pulping processes (sulfite process and kraft process), but has still limited use for easy pulped materials like straw and some hardwoods.

In this Chapter "kraft paper and paperboard" means paper and paperboard of which not less than 80% by weight of the total fibre content consists of fibres obtained by the chemical sulphate or soda processes.

All ordinary newspapers, as well as some of the cheaper grades of book and wrapping paper, are made entirely from wood, the sulphite or soda process supplying the fiber, and ground wood being used as a filler.

As with most parts of the Canadian forest products sector, Canada lagged by a decade or more in implementing new techniques such as the production of groundwood pulp and the use of a soda process for chemical pulping.

Historically soda pulping was the first successful chemical pulping method.

Soda pulping is a chemical process for making wood pulp with sodium hydroxide as the cooking chemical.

Soda pulping is another specialty process used to pulp straws, bagasse and hardwoods with high silicate content.

Soda pulping was one of the first chemical pulping methods and was invented in 1851 by Burgess (USA) and Watts (England).
