moulding sands with water glass, carried out in ester technology. Investigations are continuation of works connected to hardener based on carbonic acid’s esters, that significantly upgrades the abili...
Adding coal dust and organic carriers of the lustrous carbon to bentonite-bonded moulding sands in amounts justified by the technological regime and the use of cores and protective coatings based on o...
Adding coal dust and organic carriers of the lustrous carbon to bentonite-bonded moulding sands in amounts justified by the technological regime and the use of cores and protective coatings based on o...
The surface tension of foundry binders is a very important parameter affecting the properties of a sand-binder system. Combined with other parameters, its value determines an outcome of the process of...
The article discusses the results of an investigation carried out on the chemically bonded and CO2 blown moulding sands using selected, modified inorganic binders. The investigations make an important...
The article is devoted to the description of a new integrated system for processing and reclamation of moulding and core sands using the equipment developed by Foundry Research Institute in Krakow. Th...
A mathematical 3D model is presented, fully describing the impulse compaction process of moulding sands. The model is based on the models of the impulse head dynamics as well as of the deformation and...
The article concerns a trial of explaining the mechanism of improving the knock-out properties of moulding sands with water glass made in ester technology after using the new additive called Glassex. ...
The work presents results of research on changes of elasticity and durability properties of moulding sands with a hydrophilic binder. The research concerns the surface layer of a mould. The presented ...
The article focuses on the topic of improving the knock-out properties of moulding sand with water glass and ester hardener. It is settled that the cause of worse knock-out properties of moulding sand...
Binders used in moulding sand have the differential properties. One of the main parameters influencing on moulding sand properties is wettability of the sand grain by binding material.
