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
corrosion inhib... hiện toàn bộ

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.

A new ‘Z’ Blade Extruder Mixer with the benefits of electric drive joins the
range of hydraulically driven ‘Z’ blade extruder mixers from Winkworth Machinery
Ltd. The EMX machine is of robust construction, yet requires less floor space
and offers cost savings in applications where the heavier duty features and
automatic variable speed of the hydraulically driven machines are not required.
Mr M. F. Kooistra (54) is now president of FATIPEC for 1979–80. Currently
chairman of the Nederlandse Vereniging voor Verftechniek—NVVT, Ir. Mart F.
Kooistra took his degree as a chemical engineer in 1950 at Delft Technical
University. In the same year he joined Sikkens Paint Company at Sassenheim,
Holland, and has been connected with coatings research ever since.
This topic covers a range of pigments and powders primarily developed to give
lustre and brightness, and yet which have additional properties that enhance
their appeal for a wide range of applications. They can be produced in many
colours which are based on either nickel, aluminium, bronze or stainless steel.
