A STUDY ON DROPLET IMPACT BEHAVIOUR OF MODIFIED BIOPOLYMER ON UREA SURFACE
Controlled release fertiliser gained lots of interests because the coated layer on urea granule would control the nutrient release to reduce the nitrogen loss into the soil and optimise the nutrient uptake by plants. Biopolymer coating material is favourable as the coated material because it may...

description |
Controlled release fertiliser gained lots of interests because the coated layer on
urea granule would control the nutrient release to reduce the nitrogen loss into the soil
and optimise the nutrient uptake by plants. Biopolymer coating material is favourable
as the coated material because it may degrade and harmless to the environment. The
polymer matrix of tapioca starch-urea-borate (SUB) has potential as a controlled
release formulation. Three types of fillers which are lignin (SUB-Li), nanoclay
-b^ntojm^^SrMMTLand^nanoclay halloysite (S-HNT) were added to improve the
wettability and mechanical properties of the coating material by reinforced into SUB
matrix. In urea coating process, the wetting stage plays an important phase where
coating material spreads on urea surface to form a thin film layer which determines
the coating uniformity of coated urea. The droplet impact behaviour studies the
wettability properties of the liquid on urea surface. |
