Water retention agent

1. IntroductionWater Retaining Agent is a kind of new functional water absorbent polymer that produced
by high-tech . It contains lots of hydrophilic groups and excellent molecule
structure. It can absorb hundred times of water of its own weight in a short
time, and release afterwards slowly and absorb repeatedly. Therefore, it can form
a miniature reservoir around the plant's root, keep a moist environment and develop
water and fertilizer retaining capacity of soil effectively, increase using
rate of water and fertilizer, improve the structure and ventilation of soil,
create a good growing environment for the plant.
The Water Retaining Agent is acrylate/acrylamide copolymer. It is produced by advanced
equipment and unique techniques; therefore the product's capacity becomes
more excellent. The product's absorbing rate is high, and the gel is firm after
absorbing water. It can be used repeatedly under the soil's pressure, and keep the
soil ventilated and keep the soil from hardening. It has super capacity of absorption,
and it can release afterwards, so it can reduce running off, exaltation
the utilization of the fertilizer and agrochemical, and lower the pollution of
the environment. This product can degradable completely. It can be gradually degraded
into carbon dioxide, water and nitrogen etc. after being used in soil for
2-3 years, so it is beneficial and harmless to the soil, and it will improve the
original ecosystem environment.
2. Function and characteristics (1) It has super water absorbing capacity. It can absorb and retain rain and
irrigated water quickly, and release water slowly when the plant needed. Thus it
can guarantee the water that the plant needs for growth, prevent the waste of water
caused by evaporation, seeping, and running off, keep the soil moist for a
long time, and absorb and release repeatedly for the plant. The experiment proves
that the water retained in soil that use Water Retaining Agent is 5-15% more than
that does not use it, and it can economize 50% upwards of water.
(2) Improve the soil's structure. (Granule structure, water permeability, ventilation,
thermal capacity) Iterative contraction and expansion make lots of holes
and space in soil, increase ventilation and water permeability of soil, and improve
the environment around the root, and boost up the activity of microorganism
around the root, quicken the decomposition of organic mineral that advantageous
to root system's absorbency, accelerate the plant's growing, improve the soil's
foundation and prevent the soil become hardened and Stalinized.
(3) It can keep its stability and efficiency in all kinds of soil, for various
plants, and under different conditions of weather.
(4) It can accelerate the plant's growing, and increase the seed's germinating
rate by 5-15%, accelerate the root system's growing, and make it grow deeper and
thicker.
(5) It can economize agrochemical and fertilizer. If mix the agrochemical and
fertilizer with it, it can also retain the agrochemical and fertilizer while it
store the rain and irrigation water, and release afterwards. Thus the agrochemical
and fertilizer will not be waste because of evaporate, seeping and running off,
and increase the utilization of the agrochemical and fertilizer.
(6) It has passed the test of environment inspection organization and the hygiene
epidemic department. It is non-poisonous, harmless and has no side effect.
It makes no pollution to the environment in its using period.
(7) The product application is wide, and it can be used repeatedly, and the period
of validity can be 2~3 years.
