Purpose– The purpose of this paper is to investigate the inhibitive properties
of black pepper extract (BPE) for aluminium in 1M hydrochloric acid (HCl)
medium.Design/methodology/approach– Gravimetric, electrochemical impedance
spectroscopy, galvanostatic polarization, scanning electron microscopy with
energy dispersive X-ray examinations (SEM-EDX) techniques were used to study the

Purpose– The purpose of this paper is to investigate the synthesis of
calcium-based group of mixed metal oxide (MMO) pigments. The evaluation of these
pigments as heat and corrosion resistant was also
explored.Design/methodology/approach– Two simple synthesis techniques, namely,
co-precipitation and solid-state calcination method, were used to synthesise
nanosized MMO pigments. And then the physic... hiện toàn bộ

Fillers with different chemical properties were used to study their effects on
poly(vinyl acetate) (PVAc) emulsion wood adhesives. The elastoplastic behaviour
of the filler treated PVAc emulsions was studied using differential scanning
calorimetry and dynamic mechanical thermal analysis. The results show that the
glass transition temperature (Tg) of the polymer is not changed significantly by
the ... hiện toàn bộ
Calcium carbonate was used as a filler for polyvinyl acetate emulsion for its
application as wood adhesive. Different formulations with variable % of filler
were prepared and the shear strength of the applied adhesive on wood was
measured. It was concluded that after 24 hours the adhesives develop a
reasonable strength. It was also recommended to use the filler in the range of
10–20% by weight of ... hiện toàn bộ

PurposePoly(ethylene terephthalate) (PET) waste from soft drink bottles was
incorporated into palm olein alkyd to produce new polyol for use in polyurethane
resins as surface protection on metal surfaces.Design/methodology/approachAlkyd
was prepared from palm olein, glycerol and phthalic anhydride. PET underwent
simultaneous glycolysis and transesterification reactions with the alkyd.

Although as long ago as 1870 Adolf Bayer referred to a resinous substance formed
from reacting phenols with aldehydes, with pyrogallol and benzaldehyde used in
his experiments, this Bayer research attracted little or no interest even though
in 1891 in the journal Annalen a paper by Kleeberg described a reaction between
phenol and formaldehyde, two raw materials then becoming available in commerce.... hiện toàn bộ
PurposeThe purpose of this paper is to evaluate effects of different contents of
composite ferrotitanium pigment on corrosion protection performance of epoxy
resin coatings.Design/methodology/approachDifferent contents of composite
ferrotitanium pigment were added to the epoxy resin coatings and the corrosion
performance of the coatings were investigated by electrochemical test (in 5 wt.%
