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.
Urea formaldehyde adhesive powder is a type of adhesive that is commonly used in the woodworking and furniture industries for bonding wood and wood-based materials. It is a powdered resin that is typically mixed with water to form a glue-like substance for bonding purposes. Here are some key points about urea formaldehyde adhesive powder:
Composition: Urea formaldehyde adhesive powder is composed of urea formaldehyde resin, which is synthesized by the reaction of urea and formaldehyde. This reaction produces a thermosetting resin that is commonly used as an adhesive.
Powder Form: The adhesive is manufactured in a powdered form for ease of handling and storage. The powder is then mixed with water to form a workable adhesive solution.
Application: Urea formaldehyde adhesive powder is widely used in the bonding of wood and wood-based products, such as particleboard, plywood, and medium-density fiberboard (MDF).
It is suitable for applications where a strong and durable bond is required.
Curing Process: Urea formaldehyde adhesives are thermosetting, meaning that they undergo a curing process when exposed to heat and pressure. This process results in a cross-linked structure, providing a strong and durable bond.
Features: Urea formaldehyde adhesives offer good bonding strength, water resistance, and heat resistance.
They are cost-effective and have been widely used in the woodworking industry for many years.

FH products are Pure nonionic derived the endosperm of guar polysaccharide (Cyamopsos tetragonolobus). The products are unique with ultra-high viscosity with fastest hydration characteristics as shown in Figure 1 below. Also, when added with other drilling components, to seawater, a KCl solution or other aqueous system, the product suspension disperses readily without lumping, even under low-shear conditions generating most of its full viscosity within just a few minutes.
PRODUCT COMPATIBILITY:
FH series of products are compatible with most of the chemicals and auxiliaries used in drilling operations. However, the products are not compatible with Arabic and Crystal gums. Also, in presence of borates they form elastic gel.
PRODUCT APPLICATIONS:
FH series of products are natural, high viscosity, fast hydrating non-Newtonian hydrocolloids with suitable cross linking components in diesel slurries and are versatile for continuous mix applications, where extremely fast hydration and subsequent viscosity development is required. They are excellent viscosifiers, stabilizers, thickeners and suspending agent for use in oil-drilling, workover fluids and several other oilfield applications like hydraulic fracturing, oil well stimulation, mud drilling, oil well capping, flocculent and liquid shoring etc. The product is used as a surfactant; synthetic polymer and deformer ideally suited for all rheological requirements of water based and brine based drilling fluids.

When the temperature of urea is below 20 â?? and the relative humidity is below 70%, it will not only not absorb moisture, but also evaporate water and reduce its water content; When the temperature exceeds 20 â?? and the relative humidity is higher than 80%, it starts to absorb moisture, and becomes paste when it is serious. When the air is dried again, it will re agglomerate, which is only inferior to ammonium nitrate. When the urea aqueous solution is at 80 â??, hydrolysis and decomposition reactions will occur, forming ammonium carbamate, ammonia gas and carbon dioxide respectively. Under acid and alkaline conditions, urea will decompose faster when it is heated. Urea is easy to combine with straight chain carbohydrates to form crystalline additional compounds; It forms a variety of double salts with various inorganic compounds, such as Ca (NO3) 2 �· 4CO (NH2) 2, NH4Cl �· CO (NH2) 2, CaChemicalbookSO4 �· 4CO (NH2) 2, MgSO4 �· 4CO (NH2) 2 �· 3H2O, Mg (NO3) �· 4CO (NH2) 2 �· 2H2O, etc; It is easy to form urea phosphate, dicalcium phosphate and water with monocalcium phosphate, namely Ca (H2PO4) 2 �· H2O+CO (NH2) 2 â?? H3PO4 �· CO (NH2) 2+CaHPO4+H2O; With nitric acid, it is easy to form urea nitrate, CO (NH2) 2+HNO3 â?? CO (NH2) 2 �· HNO3, which combines and relaxes the two; It can combine with formaldehyde to form urea formaldehyde compounds (uric acid rubber shrinks), in which the higher proportion of formaldehyde is urea resin, and the lower proportion is slow-release (effective) urea.
Urea, a nitrogen-rich compound with the chemical formula CO(NH), plays a significant role in the oil and gas industry, Urea, also known as carbamide, is a highly soluble organic compound. It is synthesized on a large scale from ammonia and carbon dioxide and is primarily used in fertilizers, which accounts for about 90% of its global production.
Chemical Properties
Molecular Formula: CO(NH)
Molar Mass: 60.06 g/mol
Appearance: White, crystalline solid
Melting Point: 133C (271F)
Solubility: Highly soluble in water, forming a neutral solution
Industrial Production
The production of urea typically involves the following steps:
Ammonia Production: Sourced primarily from natural gas (methane) through the Haber-Bosch process.
Reaction with Carbon Dioxide: Ammonia reacts with carbon dioxide to produce ammonium carbamate, which is then dehydrated to form urea and water:2 3 2+ 2NH 3 +CO 2 NH 2 CONH 2 +H 2 O
Diesel Exhaust Fluid (DEF): Urea is used to reduce nitrogen oxide (NOx) emissions from diesel engines. DEF, a mixture of 32.5% urea and 67.5% deionized water, is injected into the exhaust stream of diesel engines.
Oil Drilling Fluids: Urea can be used in drilling mud formulations to enhance the efficiency of the drilling process.
Chemical Manufacturing: Urea serves as a feedstock in the production of various chemicals such as melamine and urea-formaldehyde resins.
Desulfurization: It is used in processes to remove sulfur compounds from petroleum products.
Market Dynamics
Demand: The demand for urea is largely driven by its use in agriculture. However, industrial uses, including those related to the oil and gas sector, contribute significantly to its market.
Pricing: Urea prices are influenced by the cost of natural gas, the primary raw material, and global agricultural demand cycles and NEGOTIABLE
Environmental Impact: While urea itself is not hazardous, its overuse in agriculture can lead to environmental issues such as eutrophication.
Handling and Storage: Urea should be stored in a cool, dry place away from moisture, as it is highly hygroscopic. It is considered non-toxic, but proper safety measures should be followed to avoid dust inhalation or skin contact.
Logistics: Efficient transportation and storage solutions are vital to maintain urea quality and manage costs.
Regulations: Compliance with international and local regulations regarding chemical handling, safety, and environmental impact is crucial.
Market Opportunities: Identifying and targeting markets with growing industrial and agricultural demand for urea can enhance profitability.
