DBNPA is widely used in industrial circulating water systems, large air-condition, and large centers of sewage treatment to eliminate microorganisms and algae and shuck off clay. DBNPA is also used in the process of paper making to prevent reducing the quality of paper by the generation of microorganisms. DBNPA is suitable for metal cutting of cooling liquor, recovery system of oil, latex, and ply-woods as anti-spy biocides. DBNPA has the following advantages: easy to handle; no unusual oxidation hazards; similar performance and safety in paper and oilfield applications; used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria. DBNPA has exhibited outstanding efficiency against bio-films and a broad spectrum of bacteria, fungi, and yeasts.
Additionally, DBNPA series products are used in the short-term preservation of coatings and coating additives such as latex, starch, and mineral slurries. DBNPA is a fast-acting/quick-kill biocide that is broad-spectrum and does not contain or release formaldehyde.

Rolling grinding steel media ball,grinding hot rolled ball China
Welcome to buy rolling grinding steel balls from Huamin steel ball company,which is one of the best and largest rolling grinding steel ball manufacturers and exporters in China.
**Specification of rolling grinding steel media ball:
Origin:China
Trademark:Huamin
Package: barrel or ton bags
Shipment: sea
Size:20mm-150mm
**Parameter of rolling grinding steel ball:
**Brief introduction of rolling grinding steel ball:
Grinding steel ball is a kind of forged or rolling product,which can be used for ball mill.The grinding steel ball has good surface quality,impact toughness,wear-resistance,through forged and rolled by heat treatment equipment and forging and pressing devices.
**Application
The Huamin steel grinding ball is widely used in large mines, gold, copper, Alumina ore, iron ore, aluminum ore, nonferrous metal ore, colorless metal and non metal ore mill and rare metal precious metal ore, metallurgical and mining, cement, thermal power, flue gas desulfurization, magnetic materials, chemical industry, coal water slurry, pellet, slag and ultrafine fly, fly ash, calcium carbonate, quartz sand and other industries and rod mill equipment
**Features of forging grinding steel media
1.precision size
2.high roundness and high hardness
3.wear-resistant and not easily broken
roduct Description
1 > High Hardness: Surface hardness: HRC57-67 HRC, volume hardness HRC56-64.
2 > High Impact Toughness: The impact toughness of our grinding balls is more than 12 J / cm2.
3 > Low Broken Rate: the actual broken rate is not higher than 1%.
4 > Good wear-resistant and lower wear rate.
Product Feature
1)High quality
High quality comes from every working procedure for the control . Grinding ball have no great
differences in appearance, but in the actual effect of grinding efficiency is different, this is because
the raw material, heat treatment process, equipment automation level and other factors can lead to
the steel ball steel ball lapping efficiency differences, and ultimately affect the user cost of grinding .
Every working procedure we always follow the details of the accused, by providing more wear-
resisting of grinding ball to help customers to reduce the cost of grinding.
Product Specification / Models
1 > Raw material contrast
Ordinary company : directly using the scrap or various steel grades production, traditional little
involvement in the high rate of grinding materials research and development.
houde : have a deep cooperation with The Chinese academy of sciences and steel plant , according
to different industry standard have in-depth research and development, developed raw material
with higher grinding performance.
Application
2 > Heat treatment of contrast
Ordinary company : Usually use pure water cooling quenching with insulation barrels of tempering ,
the heat treatment method is easy to cause uneven hardness, the lack of resilience, steel ball high
broken rate in practical use.
houde : Closed cooling tower for effective control of quenching temperature within the scope of the
standard, the composite heat treatment technology can improve the internal organization of steel ball,
the ball while guarantee the hardness have sufficient toughness are less likely to break.
Other Information
3 > Production craft contrast
Ordinary company : degree of automation is less than manual intervention, there is no guarantee
that the stability of each batch steel ball.
houde : Fully automated production lines, greatly reduced the manual intervention, to ensure the
stability of different batch grinding steel ball quality.
