Where can Nitrocellulose be Applied?

As a Nitrocellulose Manufacturer, share with you.

Applications of Nitrocellulose

Coatings

As a base material for coverings, will remain to be indispensable-- nitrocellulose lacquers as well as varnishes are specifically useful for accentuating timber grain.

Publishing Inks

Printing inks having Nitrocellulose Solution completely dry extremely quickly. An additional really vital advantage, especially with food packaging, is that the solvents evaporate totally.

Leather Surfaces

In natural leather surfaces-- e.g. for shoes-- the high versatility of nitrocellulose is a substantial property.

Nitrocellulose Structure

Nitrocellulose utilized for manufacturing inks as well as coverings consists of cellulose nitrate with a nitrogen content of less than 12.6 per cent. It has a damping agent-- either water or alcohol-- in a quantity of not less than 25 per cent by weight, as called for by regulation, or a gelatinizing plasticizer in an amount of not less than 18 per cent by weight. Various other kinds of nitrocellulose are not produced by and also are consequently not managed in the adhering to.

Characterisation of Nitrocellulose

Nitrocellulose as well as NC-Chips grades are qualified by their Nitrogen web content (degree of alternative) thickness (molar mass) and also.

Phlegmatiser/ stabiliser (wetting/damping representative or plasticiser).

Thickness.

The viscosity of Nitrocellulose or NC-Chips depends on the molar mass (molecular weight) of the nitrocellulose. As establishing the molar mass is much more complex than figuring out the thickness, and also as the thickness of the remedy is significant in useful terms, a thickness index is mentioned and the thickness of the nitrocellulose in a details solvent mixture is specified.

Phlegmatisers/Stabilisers.

A further grading feature of Nitrocellulose and NC-Chips is its damping agent web content as well as the sort of damping agent. Industrial nitrocellulose is required by law to contain a minimum of 25% damping agent (e.g. alcohol, water) or 18% plasticiser.

The objective of damping representatives or plasticisers is to phlegmatise or stabilise the nitrocellulose in order to deactivate the harmful properties of completely dry nitrocellulose (high flammability, high burning prices). The nitrocellulose grades supplied by damped with at least 30% alcohol or water, or when it comes to NC-Chips phlegmatised with 20% plasticiser.

The difference between Nitrocellulose as well as NC-Chips is the sort of phlegmatizer utilized (alcohol or plasticizer). The obvious difference is just their physical form as well as the approach of handling them. Within the mean thickness showed, the nitrocellulose in both Nitrocellulose as well as NC-Chips is the same.

Production.

Nitrocellulose is produced by creating cellulose to respond with nitrating acid (a blend of nitric acid and also sulfuric acid). Adhering to complicated washing as well as supporting phases, damping agents (alcohols or water) or plasticizers are added to the nitrocellulose which is then marketed as Nitrocellulose or NC-Chips.
