| LH-306
Tripolymer of phosphono-Acrylic Acids |
LH-306, a new kind of copolymer domestically, can be applied as a scale
inhibitor and dispersant. Its characteristics are better than that of T-225 from Japan.
This copolymer is compatible with sodium hexametaphosphate, sodium tripolyphosphate, HEDP,
ATMP, EDTMP, etc. Its combining use with zinc salt and molybdate can improve the corrosion
inhibitation. Under caustic conditions and high temperature, it can tolerate high content
of calcium carbanate and calcium phosphate. It is also a good dispersant of iron scale and
zinc scale.
LH-306 can be used as a scale inhibitor and dispersant for the industrial
recirculating cooling water treatment in the fields of chemical, oil, metallurgy, and
power etc. It also can be applied for oil field water treatment and boiler water
treatment.

| LH-315
2-phosphono-butane-1, 2, 4-tricarboxylicacid (PBTCA) |
LH-315 is an innovative scale and corrosion inhibitor with high effectiveness.
Its excellent characteristics are better at scale inhibition than that of traditional
phosphonic acids, such as ATMP, HEDP, EDTMP etc, specially at scale inhibition to calcium
canbonate and calcium phosphate. LH-315 and its solution have good improve zinc salt
solubility. It also can keep good ability even under alkaline condition (PH=9.5). Hence,
it is possible to make up the formula containing zinc salt under cautic conditions. It is
more tolerant of high temperature,. oxidation and chloridization, than traditional
phosphonic acids. Besides, LH-315 is an effective dispersant for the industrial
recirculating water containing iron or high turbidness.
LH-315 can be applied as a scale inhibitor and dispersant for the industrial
recirculating water treatment in the fields of chemical, oil, power and so on..

| LH-101
Cleaning Agent |
LH-101 is a chemical cleaning agent with well permeating and decontaminating
ability. It is free of corrosive acids and bases. Therefore it does not cause corrosion
over metal equipment. It permeates into the contaminants and wets them making them peel
easily and carried off by the flowing water. If it is used together with precoating agent,
the precoating effect and the ability of corrosion inhibition for metal equipments can be
improved.
LH-101 can be applied in equipment cleaning for industrial recirculating water
system before running. Generally, the cleaning is conducted before precoating, to remove
dirt ,grease, rust and slime etc.
|
| LH-309
Maleic Anhydride polymer |
It is an organic antiscaling agent with high effectiveness. The water is
adaptable to a solvent for the synthesis of Maleic anhydride polymer. The agent can keep
good ability at antiscaling even under alkaline condition (PH=9-11.5) and high temperature
(about 300ìC). It is not volatile with vapouration so that it does not contaminate
the vapour .Better results will happen if it is used together with phosphonic acids or
sulphonic acids.
|
| LH-310
Maleic acid and acrylic acid copolymer |
It is an innovative product domestically. It is a copolymer of Maleic acid and
acrylic acid with water as the solvent. As a highly effective scale inhibitor, it can be
used under the caustic condition, about 300ìC. It is widely used in the treatment
of boiler water and recirculating water systems for oil and fertilizer etc.
