1.printing

Textile dyes and chemicals sodium alginate is mainly uesd in textile printing paste, we are the best manufacturer in China

Sodium alginate was used in Textile dyes and chemicals for an age-old period, that  it was used in starching, packing and printing, mainly in textile print processing as a reactive printing agent with a special property.

In fact  the printing agent mixed with low - viscosity Sodium Alginate is stabler than with the other viscosity, which is the results to produce a super-high content of printing agent

 

 2.welding rods  

Coatings are applied to welding rods or electrodes to act as a flux and to control the conditions in the immediate vicinity of the weld, such as temperature or oxygen and hydrogen availability. The dry ingredients of the coating are mixed with sodium silicate (water glass) which gives some of the plasticity necessary for extrusion of the coating onto the rod and which also acts as the binder for the dried coating on the rod. However the wet silicate has no binding action and does not provide sufficient lubrication to allow effective and smooth extrusion. An additional lubricant is needed, and a binder which will hold the damp mass together before extrusion and maintain the shape of the coating on the rod during drying and baking. Alginates are used to meet these requirements.

3.The quantities of alginates used are very dependent on the type of welding rod being coated and the extrusion equipment being used. For soluble alginates it may be 0.4-1.2% or low-hydrogen welding rods and 0.15-0.25% for acid and organigc types. For the thixotropic alginates, manufacturers often find it more effective to use a mixture of calcium alginate and sodium alginate with a total alginate content of 0.4-0.6% for low hydrogen electrodes.
