Chemical
properties:Melamine presents alkalescence,
can react with various acidums to generate melamine salt.
In strong acid or strong alkali liquor, melamine will hydrolyze---amido
group will be slowly replaced by hydroxyl, thus generate ammeline,
Cyanuric Acid and Ammelide. It can react with aldehydes to
produce addition compounds . Among them, the reaction of melamine
and formalin is the most important part.
Packaging: Net
weight 25kg, 500kg, and 1,000kg in polypropylene woven bag
and inner low-pressure PE plastic bag. Also we can provide
other type packaging according to customer's requirement.
Storage: Kept
in shady and ventilative places. Don't be stored or transported
together with acid or oxidizer.
The application state of melamine
Melamine is a semi-finished product in organic chemicalindustry
with even structure and vast applications; it is mainly used
as the material to produce melamine formaldehyde (MF) colophony.
Owning the abilities of fire-resistant, water-resistant, hot-resistant,
age-preventing, electric arc resistant, bearing chemical corruption,
perfect  insulation capability, gloss grade, and machinery
intention, and good thermal-setting capacity, it is
widely used in wood, plastic, dope, paper-making, textile
industry, leather, electric, and medicine, etc.
The actual applications are:
1, decorative veneer plywood.
2, coating
3, moulding powder
4, paper
5, Mixed with other materials, melamine formaldehyde (MF)
resin also can be used to produce fabric finished agent, tannage
agent of leather, glazing agent, waterproof agent, rubber
adhesive, high efficient water reducing agent of cement (naphthalene
as material), and nitridizing agent of steel. |
