Effectiveness of wax emulsions in die-cast ceramic blank systems
In the production process of ceramic products, maintaining the strength, compressive properties, bending strength and fracture strength of ceramic blanks is closely related to the effect of the binder, because in the ceramic injection moulding process, the wax emulsion as a ceramic binder can be evenly mixed with the powder, heated to play the role of lubrication, so that the powder has good fluidity, injection molding a complete blank, while the wax emulsion can play a role in maintaining the shape of the blank after injection moulding and degreasing This is why wax emulsions can be used as an alternative to waxes. This is why wax emulsions can replace clay as a ceramic binder.
With the increasing quality requirements of ceramic products, water-based wax emulsions, which are organic polymer binders, are gradually being used in the production of ceramics. As the wax emulsion has the characteristics of non-volatility, good dispersion, uniform film laying, good lubrication, good fluidity and permeability, adhesion, no metal impurities, etc. The application of wax emulsion in the production process of ceramics can not only improve the fluidity of the powder and the release of the injection pieces, but also improve the denseness of the injection pieces and the strength of the raw billet.
Among all wax emulsion malaysia products, paraffin emulsion has low molecular weight, low viscosity, good wettability with powder and no chemical reaction between them, simple degreasing process, minimal residue after degreasing, no environmental pollution, more effective as a binder and also enhances the strength of ceramic blanks and improves the performance of ceramic products after sintering.
Water-based wax additives are a very important part of leather finishing agents, which can effectively improve the feel of the leather and enhance the overall performance of the leather. Compared to polyethylene wax emulsions, oxidised polyethylene wax emulsions form paint films with higher gloss, higher density, higher hardness, better feel and excellent durability, which can replace expensive animal wax emulsions and are widely used in leather, flooring, automotive, furniture, paper, textiles and other fields.
Oxide polyethylene wax emulsions can be used without heating and melting or dissolving with organic solvents. They form a uniform film, have good coverage, are water resistant and lubricious in common, have anti-adhesive, brittle, tough, honourable and glossy properties and are easy to compound with aqueous solutions or emulsions of other substances.
In addition, Wax emulsions are a very important part of the water-based varnish system. Wax emulsion types mainly include paraffin wax emulsions and polyethylene wax emulsions, which can effectively enhance the abrasion resistance of water-based varnishes, prevent sticking and give the printed product a skin feel.
