dc.description.abstract | U radu su prikazani rezultati ispitivanja mehaničkih osobina PVC (polivinil hlorid) mešavine koja sadrži krečnjak sa kalcitom, kao osnovnim mineralom, modifikovanim stearinskom kiselinom 'suvim' i 'mokrim' postupkom. Ispitivano je: čvrstoća pri zatezanju, izduženje pri zatezanju, čvrstoća pri kidanju, izduženje pri kidanju i temperatura omekšavanja po Vikat-u. Rezultati su pokazali da PVC mešavina koja sadrži kalcit modifikovan 'mokrim' postupkom ima bolje mehaničke osobine od one koja sadrži kalcit modifikovan 'suvim' postupkom u uslovima kada je postignut najveći stepen obloženosti od 99.90%. Uzorak PVC mešavine koji sadrži kalcit modifikovan 'mokrim' postupkom sa 1.5% stearinske kiseline ima čvrstoću pri zatezanju 54.20 MPa i čvrstoću pri kidanju 38.20 MPa, dok uzorak koji sadrži kalcit modifikovan 'suvim' postupkom sa 3% stearinske kiseline ima čvrstoću pri zatezanju 53.20 MPa i čvrstoću pri kidanju 37.90 MPa. . | sr |
dc.description.abstract | This paper presents the results of mechanical properties testing of the PVC (Polyvinyl Chloride) mix containing limestone with calcite, as a basic mineral, modified by stearic acid using wet and dry procedures. The following testing was conducted: ultimate tensile strength, tensile elongation, breaking strength, elongation at break, and Vikat softening temperature. The results showed that the PVC mix containing calcite which was modified by wet procedure had better mechanical properties than the PVC mix containing calcite modified by dry procedure in conditions when the highest degree of coating of 99.90% was achieved. The PVC mix sample containing calcite modified by wet procedure with 1.5% of stearic acid had ultimate tensile strength of 54.20MPa and breaking strength of 38.20MPa, while the sample containing calcite modified by dry procedure with 3% of stearic acid had ultimate tensile strength of 53.20MPa and breaking strength of 37.90MPa. . | en |
