Simultaneous recovery of high-purity copper and polyvinyl chloride
PVC coverings typically contain plasticizers for flexibility. As such, PVC cables become brittle after plasticizer extraction, causing them to be easily crushed by physical impact. Hence, we extracted the plasticizers from the PVC coverings of electric cables using organic solvents, and then crushed the obtained cable samples by ball milling.
Plasticizer for poly(vinyl chloride) from cardanol as a renewable
High purity, small scale esterification was performed in order to study the plasticizing effectiveness of the derived plasticizer, but let us produce no more than 7.5 g of plasticizer. This high purity esterification was obtained using, 7 g of cardanol and 6.57 ml (7.09 mol, 3 equivalents) of acetic anhydride, diluted in 5 ml di pyridine, and held for 2 h at 50 °C.
8042-47-5 - Mineral oil, high purity - J62592 - Alfa Aesar
J62592 Mineral oil, high purity . CAS Number. ... It can be used as a plasticizer, catalyst carrier and pigment dispersant.
Optimization of the tape casting process for development of high
It was shown that the optimized formulation for dispersant, binder, plasticizer/binder ratio and solid loading was 2.22 wt%, 5.90 wt%, 1.0 and 31 vol%, respectively. Alumina ceramics showed improved mechanical properties, with the indentation hardness and fracture toughness as 15.91±0.15 GPa and 4.29±0.06 MPa 1/2 Keywords A. Tape casting

- Which dispersant is used for alumina slurries?
- The preparation of concentrated suspensions with high stability is crucial for tape casting. Dispersant plays an important role in the developing of high solid loading slurries with low viscosity. In this study, castor oil, phosphate ester and castor oil phosphate were selected as dispersants for alumina suspensions.
- What is uniqchem dispersant technology?
- n solvent on their wish. UNIQCHEM dispersant technology enables the production of highly loaded pigments, high stability a
- Does dispersant content influence mechanical properties of as-sintered alumina samples?
- The influence of dispersant content, binder content, plasticizer/binder ratio and solid loading on the green sheet and some mechanical properties of as-sintered alumina samples were also investigated.
- What are dispersing additives?
- at the pigment surface.Dispersing additives, which adsorb on the pigment surface, facilitate liquid/solid interfacial interactions and help to replace the air/solid interface by a liqui medium/solid interface.The grinding process can be regarded as a
- Which type of dispersant is used for different polarity?
- the dispersant is used. Therefore there are different kind of dispersants for different medi polarity available. Solid disper ant on pigment (SOP) =A ladder series of polymeric dosage levels should be evaluated based aroun
- What dispersants are used for stabilizing Al 2 O 3 suspensions?
- The dispersants used for stabilizing the Al 2 O 3 suspensions were castor oil phosphate (Haian Petroleum Chemical Co., Ltd., Jiangsu, China), castor oil (CP, Aladdin Industrial Co., Ltd., Shanghai, China), phosphate ester (PE-1168, Witco Chemicals, USA).
