During the process of retrieving the alkaline from the paper making black liquid, due to the high temperature, high

alkalescence, high content of silicon, magnesium, calcium, ox and other solid material as well as the high viscosity, severe

scale formation is caused in the evaporator, which is even blocked. People have to stop to wash it, which not only raise the

cost but also affect the normal production and is regarded as a difficult problem in alkaline recovery.

The anti-scale specially used in black liquid evaporator in papermaking is composed of surface active agent, dispersant,

viscosity depressant etc.when put into the black liquid, the viscosity depressant in the anti-scale will have chemical

reaction with silicon, oxalate and all kinds of sugar in the black liquid to let it loose the viscosity, floating in the black liquid.

Surface active agent and the dispersant will disperse the calcium, magnesium, silicon ion in the black water to the

maximum extent, enhancing its anti- precipitability and liquidity. As a result, they will not scale in the surface of evaporator

but instead keep it clean without scale. Dispersant will have chemical reaction with the scale on the surface of evaporator

to dissolve it and make it break off and in this way, the old scale will be rid of.The low viscosity of the black water will

prevent the new scale formation. The purge of the old scale enhance the speed of the heat conductivity and accordingly

the speed of the water evaporation is increased, which shorten the time of black water evaporation. All these make the

alkaline recovery more efficient and save the cost with more profits gained.



Dosage: 30-50g/MT black liquor

Dilute the product in the mixing tank, and then though dosage pump to the evaporator together with black liquor according

to scale. The product should not been stored for long time after being diluted. It should be diluted when needed.

boiler, open the handhold, remove the visible scale deposit to prevent conduit blockage, then, the boiler may turn into normal

operation again. It would be better if the condense index of boiler water was controlled within 10. Other parameters may refer to

related regulations (boiler water pH10-12, for example). pH value should not be lower than 7.

The material of medicate tank should be in plastic, concrete tank should be pretreated by anticorrosion method, otherwise. It will

be eroded by the medicine, and the hardness will be increasedmuch high.

Total hardness of boiler make-up water should be lower than 200mg/l. Once too high hardness is countered, lime or other

methods should be used to lower it.

little contents of ca2+ and mg2+ ions in soft water, the corrosion inhibition is a difficult question for soften water system. Through

exposure to uv to form ammonia, hydrogen, and nitrogen, which may be explosive with a blue flame when catalyzed by metal

oxides and some metals such as platinum or raney nickel. It has dibasic and very reactive properties. It is used as a

component in jet fuels because it produce a large amount of heat when burned. It is used as rocket fuel.it is used as an oxygen

scavenger for water boiler feed and heating systems to prevent corrosion damage. It is used as a reducing agent for the

recovery of precious metals. It is used as a polymerization catalyst and a chain extender in urethane coatings. It is used as an

auxiliary in photographic industry to prevent discolouration. It is used as an intermediate for pharmaceuticals, stabilizers and

water treatment chemicals.

It and its derivatives are versatile intermediates. They have active applications in organic synthesis for agrochemicals,

pharmaceuticals, photographic, heat stabilizers, polymerization catalysts, flame- retardants, blowing agents for plastics,

explosives, and dyes. Recently, hydrazine is applied to lcd (liquid crystal displays) as the fuel to make faster thin-film

YBASD-200 is used for RO, NF and UF system. It can effectively inhibit scaling on membrane surface, improve water quality

and reduce operation cost. It has the following properties:

(1) Original liquid is 11 times concentrate, 90% transportation cost and storage space is saved.

(2) Prevent pollution from inorganic salt, metal scale and some organic substances;

(3) Not flocculate with ferric oxide, aluminia oxide or silica oxide to form suspended substance;

(4) Effectively control the pollution of ferric, aluminium and heavy metal;

(5) No content of any phosphate of phosphorous;

(6) Used in RO CA, TFC, NF and UF membranes;

(7) Good solubility and stability;

(8) Stable in extreme ph and temperature;

(9) Due to YBASD-200 special molecular structure. It is safe to membrane. even high medicine input (equipment trouble, for

example) will not lead to its deposit, crystallization or adsorption on membrane surface and lead to membrane blockage.



Mix with RO outflow or desalted water. The dosage should be determined by water quality and referred to suppliers. A dosage of

3ppm is preferred.


Original liquid is 11 times concentrate, 5 gallon per barrel (22.7kg); after dilution by 11 times, it turns to 250 kg standard liquid.

(1) Suitable for all aromatic polyamide membranes;

(2) Low froth formula;

(3) Diluent pH 1.0-3.0;

(4) Liquid chemicals, mix well;

(5) Can be used repeatedly.

YB-260 is an acid liquid formula. It can remove metal hydroxide, calcium carbonate and other types of scales.

DosageDosageDosageDosage ::::

Dilute to 1-3% (1:45)



(1) Check water box, pipeline and filter, change the filter material if needed.

(2) Input q.v. RO effluence to water box.

(3) Input q.v. YB-260 to water box, mix the solution with water pump, measure pH.

(4) Clean the system repeatedly, measure pH for 5-20 minutes.After pH rise to 4, input q.v. YB-260 or acid,

till pH not rise, meaning cleaning is end.

(5) If pollution is serious, sometimes the first batch detergent should be evacuated and the next batch

should be required.

(6) Pay attention to solution temperature, don’t exceed the required temperature.

The operation stability of RO system is determined by the pretreatment of original water quality. For any RO system, it would be

polluted after operation for 3-12 months, thus chemical cleaning is required. YB-261 is an alkali detergent designed for removal

of oil, organic substances and bio-mucosa. It has the following properties:

(1) Suitable for all aromatic polyamide and acetate acid membranes;

(2) Effectively remove oil, organic substances and bio-mucosa from membrane surface;

(3) Temperature increased, the effect will be better;

(4) Diluent pH 10.5±0.5;

(5) Liquid chemicals, mix well;

(6) Can be used repeatedly.
