How to distinguish the quality of the Sn-salt electrolytic coloring additives

According to our company's years of experience in the industry and customer feedback, we have learned that there are some problems in many Sn-Salt Electrolytic Coloring Agent in the market:

1.Many Sn-salt coloring additives contain benzene, which is a first-grade carcinogenic substance. The long-term use of Sn-Salt Electrolytic Coloring Additives containing benzene has great harm to the operating technical workers in the workshop. Severe coma, convulsions, and circulatory failure leading to death.

2. Poor stability and turbidity of tank liquid.

3. Coloring tank coloring background color is not stable. After the profile coloring, it is easy to have problems such as Yin and Yang and color unevenness.

The Sn-salt electrolytic coloring agent produced by our company is a new environmental protection product. It has avoided the common problems and has been well feedback by new and old customers.

1.Our company's formula absolutely does not contain benzene harmful substances.

2.This product is especially stable for tin sulfate and stable for pigmentation. It is the purest blue and yellow color system in the market, which is very clear and easy to grasp.

3.The color tank is colorless and transparent, as clear as water. Low cost, good quality, high yield. The tank is well maintained and the production wastewater is easy to be treated.

Our company is mainly engaged in the research, development, production and marketing of wastewater treatment chemical products (such as:Polyacrylamide,Alkali Aluminium Chloride,Chrome Removal Agentetc) and aluminum surface treatment chemical products (Neutralizing Agent,Sealing Agent etc)We use chemical reactions to decompose the pollutants in sewage, and always abide by the management concept of "Honesty first, Customer first, Quality first". We are always ready to do our best for you!

Principles for selection of sewage treatment processes

1. The main technical and economic indexes of process selection include: treatment of unit water investment, reduction of unit pollution investment, treatment of unit water consumption and cost, reduction of unit pollutant power consumption and cost, occupation of land, operation performance reliability, management and maintenance of the degree of difficulty, overall environmental benefits and so on.

2. Urban wastewater treatment technology should be selected according to the treatment scale, water quality characteristics, environmental functions of the receiving water body, local actual conditions and requirements, and selected after comprehensive technical and economic comparison.

3. It is necessary to determine the influent water quality of sewage, optimize the parameters of process design, and make a detailed investigation or determination of the current water quality characteristics of sewage, and make a reasonable analysis and prediction. The composition of water quality is complex. When special, the dynamic test of sewage treatment process should be carried out, and the pilot study should be carried out if necessary.

4. The new process should be adopted actively and prudently. For the new process that is applied for the first time, it must pass pilot test and production test, and provide reliable design parameters before application.

5. In the construction of the same sewage plant by stages, the same process should be adopted in each stage, and the construction scale of each stage should be the same as possible.

Technology of waste Water Recycling and treatment in Printing and dyeing Industry

Printing and dyeing industry uses a large amount of water.Usually,the water consumption of 1 ton of textile for each printing and dyeing process is 100 ~ 200 tons, of which 80% of the dyeing wastewater discharged. Commonly used printing and dyeing wastewater treatment methods are recycling and harmless treatment.

Recycling is divided into three aspects:

1. The wastewater can be recycled according to the characteristics of water quality, such as bleaching and cooking wastewater and dyeing printing wastewater can be recycled separately, the former can be used for convection washing.

2. The recovery and utilization of alkali liquor is usually recovered by evaporation method. If the amount of alkali liquor is large, it can be recovered by evaporation. The amount of alkali liquor is small and can be recovered by evaporation of film.


3. The recovery and utilization of dyestuffs, such as the acidizing of the sulphide acid, colloidal particles, suspended in the residual solution, and recovery and utilization after precipitation and filtration.


There are three different methods for the innocuous treatment of printing and dyeing wastewater:

1. Physical treatment including precipitation and adsorption, and so on. The precipitation method is mainly used to remove the suspended matter in the wastewater, and the adsorption method is mainly used to remove the dissolved pollutants and decolorization.

2. Chemical treatment including neutralization, coagulation and oxidation, etc. The neutralization method can adjust the PH of wastewater and reduce the chroma of wastewater。The coagulation method is to remove disperse dyes and colloids from wastewater.The oxidation method is to oxidize the reducing substances in waste water and precipitate vulcanized dyes and vat dyes.


3. Biological treatment including activated sludge, biological turntable, biological drum and biological contact oxidation, etc. In order to improve the effluent quality and meet the discharge standards or recovery requirements, it is often necessary to adopt several methods of combined treatment.

How SCR technology works?

AdBlue  DEF is a consumable that must be used in SCR technology.

SCR technology uses a catalyst system can effectively reduced the emission of nitrogen oxides and solid particles produced by diesel engines into nitrogen and water.The main components of the SCR system include the catalyst, the AdBlue injection unit, the urea tank and the AdBlue dose controller.

Process of SCR technolog : the urea tank automatically ejects the AdBlue (diesel exhaust fluid ) when nitrogen oxides are found in the exhaust pipe and the oxidation-reduction reaction of AdBlue and nitrogen oxides in SCR catalytic reaction tank produces non-pollution nitrogen and water.

With the intelligent control of SCR system, the car will be unable to start when the AdBlue in the urea tank is insufficient .In order to ensure the normal running of the vehicle, there should be sufficient AdBlue for the vehicle.

TRIS, Bis-Tris, Tricine, TES, TAPS, What is the difference in application?

TRIS(Tris(Hydroxymethyl)Aminomethane), Bis-Tris, Tricine, TES, TAPS are buffers commonly used in biochemical experiments and molecular biology experiments, and they all contain the structure of TRIS. Then what are the differences in application between these buffers?

We hope that the following table could solve your doubts.

Table 1. The application of TRIS, Bis-Tris, Tricine, TES, TAPS

In specific use, buffers containing the TRIS (CAS：77-86-1) structure will form a strong or weak complex with a variety of metal ions, so the stability constant should be taken into account. In addition, the buffer range and the appropriate type of experiment also should be considered in order to obtain the best experimental results.
