Supplier From China
Jul-31-21

Product description

To satisfy the requirement for quick measurement of DC resistance of transformer, our Company has developed three-channel, DC resistance tester aiming at YN connection winding. The tester can fulfill functions such as simultaneous energization on three phases, independent current sampling, voltage sampling, as well as simultaneous measurement and display of three-phase resistance value and three-phase unbalance rate, thus can significantly reduce test time for DC resistance of transformer, solve the problem of long test duration for DC resistance of each tapped winding of electric power transformer. It requires only 1/3 of the time required by traditional method

Commodity: Synthetic Cryolite
Formula: Na3AlF6
M.W.: 209.95

Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Specifications:
Appearance white powder
F 52% min
Al 12% min
Na 33% max
SiO2 0.36% max
Fe2O3 0.08% max
CaO 0.5% max
P2O5 0.03% max
SO4 0.6% max
H2O 0.4% max
Loss on ignition 2 % max

Uses: Its mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for resin and rubber-boned abrasive wheels.

We are supplier and exporter of Hematite Powder.

Hematite Powder is a mineral, coloured black to steel. It is mined as a main of iron ore and used as a weighting agent in oil drilling. It is the mineral form of iron(III) oxide (Fe2O3). Fluids weighted with API Hematite Powder contain fewer solids by volume than, making higher mud fluids possible. API Grade Hematite Powder is applicable in all types of drilling fluids, including freshwater, seawater and oil-base muds. It is used as a density increasing product, used as a weighting agent and in the paint industry. Hematite is also a harder mineral than Barite so it is more resistant to particle size degradation.

High Density Hematite Powder API Grade -SG = 5.19 - 5.47 -Fe2O3 = 96.70% -Fe = 71.82% -SiO2 = 0.89% -Mesh Size (passing at 98%) = 325

Ethanol alcohol distillation column
1. It is standard 95-96% alcohol equipment. Also it can distill pure water.
2.The distillation system has  three columns  and  continuous  distillation  process.The process is the  same as industrial(large scale) alcohol equipment.
 Mash distillation  column distills  fermented  mash or light alcohol  to 50% alcohol ethanol .
It has red copper bubble cap trays, standard design. It auto continuously feeds material liquid, auto continuously produces 50% alcohol ethanol and auto continuously discharges waste,  ethanol discharge in waste 0.05%, better than international standard requirements.
The first rectification distillation  column  increases  alcohol degree  to 70-75% ,  separates  fusel oil and high boiling point  Impurities.  It auto discharges waste water,  ethanol discharge in waste 0.05%, better than international standard requirements.
The second rectification distillation  column  increases alcohol degree to 95%,  separates low boiling point  impurities  like acetaldehyde and methanol .
3.  The rectification system uses  industrial(large scale) standard process, but the whole set alcohol equipments are installed in one frame, like integration  module, even  you can run it by a button.

Formalin

$100
MOQ: 100  Metric Tonnes
 
Formalin is a solution of formaldehyde gas dissolved in water. Formaldehyde is a colorless, strong-smelling gas that is commonly used in a liquid form, as formalin, for various industrial applications. Here are some key points about formalin:
Chemical Composition: Formalin is typically a 37% aqueous (water-based) solution of formaldehyde. The remaining percentage is water.
Uses:
Preservation: Formalin is widely used as a preservative for biological specimens. It helps to prevent decay and decomposition, making it essential in laboratories, museums, and medical facilities for preserving tissues and specimens.
Disinfectant: It has antimicrobial properties, and as such, formalin solutions are sometimes used as disinfectants and biocides.
Textile Industry: Formalin can be used in the textile industry for wrinkle-resistant finishes on fabrics.
Health and Safety Concerns:
Formalin is a strong irritant and can be harmful if inhaled, ingested, or comes into contact with the skin.
Prolonged or repeated exposure to formaldehyde can cause respiratory irritation and may be associated with certain health risks.
Proper ventilation and personal protective equipment are recommended when working with formalin.
Regulation:
Due to its potential health risks, the use and handling of formalin are subject to regulations and guidelines in many countries. These regulations aim to ensure safe practices and protect workers and the environment.
