Ceramic harenae sinted pro fornace frigore core arca
Arca frigida methodus refertur ad resinae harenae processum formantem, qui catalyzum/durescit flatu gasi vel aerosol, et statim in cella temperie formatur.Communis methodus est methodus triethylamine, quae resinae phenolico-urethanae utitur et triethylamine flatu gasi induratur.Proprietates huius processus sunt: nucleus arena adhiberi potest diu, forma tractio temporis brevis est, productio efficientia alta est, et humilis vis consummatio.
Diesel dejectiones machinae, ut caudices cylindrici, capita cylindrici, attractio et fistulae, etc., quaedam nuclei implicati figuras habent et particulas in locis crucis-sectionalibus partiales, quae prona sunt in falsis offa, fracturas, etc., vel venae apparent in flatura ob magnam silicae arenae expansionem.Probabilitas defectuum sicut arena viscosa et pori est etiam relative alta.
Utens arena ceramica vel mixtura harenae ceramicae et pro proportione arenae silicae, addita resinae moles per 20-30% minuitur, et praedicta vitia signanter emendantur.Eodem tempore, core arena collapsibilitatem bonam habet, quae inposuit quod purgatio ejiciendi reducit.Quam ob rem, magis ac magis machinamentum Diesel fundorum fusorum assumpsit ceramicam arenam frigidam nucleum thecam technologiam.
