Quality indicators

　　Corrosion and scale inhibitors a multifunctional water treatment chemical agent specifically used in industrial water systems to prevent equipment scaling and corrosion.This type of preparation effectively controls the deposition of inorganic salts in water through scientific chemical ratios,while inhibiting the corrosion process of metal equipment.As a core chemical in the field of industrial water treatment,corrosion and scale inhibitors play an irreplaceable role in ensuring the safe and stable operation of production equipment,extending equipment service life,reducing energy consumption and maintenance costs.

　　1.Core components and type characteristics

　　Scale inhibitors are composite preparations carefully formulated from various chemical components,and their core components can be divided into two categories based on their functions:corrosion and scale inhibitors and corrosion inhibitors.Common anti scaling components include organic phosphates,polycarboxylate compounds,and sulfonic acid copolymers,which can effectively interfere with the formation process of inorganic salt scale.The corrosion inhibition components mainly include azole compounds,organic phosphonic acids,tungstate salts,etc.,which form a protective film on the metal surface to inhibit the corrosion process.

　　Taking the commonly used high-efficiency corrosion and scale inhibitors in the market as an example,their typical ratio usually includes 45%-60%organic phosphate and acrylic copolymer as the basic chelating component,20%-30%polycarboxylic acid polymer as the dispersion system,and 8%-15%azole copper corrosion inhibitor and tungstate as the corrosion inhibition enhancement component.This scientific ratio ensures that the product can effectively prevent scale formation and provide reliable corrosion protection.

　　According to their chemical composition and application characteristics,corrosion and scale inhibitors can be divided into the following main types:

　　Universal corrosion and scale inhibitor:such as HS-670 corrosion and scale inhibitor,which is made of imported raw materials and reasonably proportioned according to the characteristics of domestic water quality.It is widely used in boiler water and circulating water softening treatment,which can effectively control inorganic scaling,chelate calcium and magnesium ions in water,and prevent crystal growth by twisting the scaling crystals.This type of product will not produce insoluble sediment after exerting its scale inhibition effect,which can extend the system cleaning cycle,prolong the service life of equipment,and reduce operating costs.

　　High temperature and high alkalinity special type:such as JG-630 corrosion and scale inhibitor,its composite formula contains organic phosphate,organic phosphine carboxylic acid,copper corrosion inhibitor and strong dispersant,which is very suitable for cooling water with high temperature,high alkalinity and high hardness,achieving the functions of scale prevention,corrosion prevention and sediment formation prevention.This type of product has a synergistic effect,with organic phosphates and polyphosphate carboxylates forming a"cathodic corrosion inhibitor",which has excellent corrosion inhibition effect on carbon steel and stainless steel metals.

　　High concentration multiple type:such as SGR0806 high concentration multiple scale and corrosion inhibitor,which is a green and environmentally friendly formula water stabilizer containing high-efficiency scale and dispersion agents,multi-component copolymers,high-efficiency corrosion inhibitors,and additives.It is particularly suitable for use in high concentration multiple(more than 5 times)circulating water systems,and can ensure the long-term safe and stable operation of the circulating water system under harsh conditions such as water quality scaling,strong corrosion tendency,and easy growth of bacteria and algae.

　　One dose multi effect type:such as KSH-02 corrosion and scale inhibitor,which mainly uses special chemical components such as imidazoline and has the function of one dose multi effect.It not only provides good corrosion inhibition ability(corrosion inhibition rate≥70%),but also has significant scale inhibition performance(scale inhibition rate≥80%).It is widely used in the anti-corrosion and scale prevention of oilfield produced water systems,thermal pipeline systems,and cooling water.

　　2.Application scenarios of corrosion and scale inhibitors

　　Power industry:In thermal power plants,the cooling water system is a key link to ensure the normal operation of the generator set.During the circulation process,cooling water is prone to scaling on the surfaces of equipment such as condensers and cooling towers,and can also cause corrosion to metal equipment.The use of corrosion and scale inhibitors can effectively prevent scaling and corrosion in cooling water systems,improve cooling efficiency,reduce power generation energy consumption,and extend the service life of equipment.For example,after adding appropriate corrosion and scale inhibitors to the cooling water system of a certain thermal power plant,the end difference of the condenser was significantly reduced,the vacuum degree was increased,and the coal consumption for power generation was significantly reduced.

　　Chemical industry:In the chemical production process,many processes require water as a cooling medium or reaction solvent.Impurities and chemicals in water can cause serious corrosion and scaling problems to equipment.Scale inhibitors can be selected and formulated according to different chemical processes and water quality conditions to ensure the stable operation of chemical equipment.For example,in the production of synthetic ammonia,the use of corrosion and scale inhibitors can prevent scaling and corrosion of equipment such as heat exchangers and pipelines,improve production efficiency and product quality.

　　Oil industry:Water treatment is an important link in the process of oil extraction and refining.Oilfield water injection and cooling water systems in refineries are facing challenges of scaling and corrosion.Scale inhibitors can effectively solve these problems and ensure the normal operation of petroleum production.For example,in oilfield water injection,adding corrosion and scale inhibitors can prevent scaling and corrosion of water injection pipelines and reservoir casings,improve water injection efficiency,and extend the service life of oil wells.

　　Metallurgical industry:During the metallurgical production process,high temperature,high humidity,and highly corrosive environments cause significant damage to equipment.Scale inhibitors can be applied to cooling water systems,acid pickling solutions,etc.in metallurgical enterprises to protect equipment from the effects of corrosion and scaling.For example,in the cooling water system of continuous casting machines in steel enterprises,the use of corrosion and scale inhibitors can prevent scaling and corrosion of equipment such as crystallizers and secondary cooling zones,and improve the quality and production efficiency of continuous casting billets.

　　3.Safe operation of corrosion and scale inhibitors

　　As a chemical agent,corrosion and scale inhibitors must comply with corresponding safety regulations during use,storage,and transportation to ensure personnel safety and prevent environmental damage.The safety risks of different formulations of corrosion and scale inhibitors vary,so it is important to carefully read the product safety technical manual before use to understand specific risk information and protective measures.

　　In terms of usage and operation,most corrosion and scale inhibitors have a certain degree of irritation to the skin,eyes,and respiratory tract,and appropriate protective measures need to be taken.Taking HS-670 corrosion and scale inhibitor as an example,the manufacturer explicitly requires wearing latex gloves,protective goggles,and protective clothing during operation.If it splashes into the eyes,immediately rinse the eyes with plenty of water and seek medical attention promptly.At the same time,it is necessary to prevent the product from overflowing onto the cement floor to avoid corrosion.If it corrodes the floor,please rinse it immediately with clean water.These protective measures,although simple,are crucial for ensuring the safety of operators and cannot be ignored.

　　Scale inhibitors play an indispensable role in industrial water treatment.By selecting and using corrosion and scale inhibitors reasonably,the problems of scaling and corrosion in water treatment processes can be effectively solved,the operating efficiency and service life of equipment can be improved,production costs can be reduced,and environmental pollution can be minimized,providing strong guarantees for achieving sustainable industrial development.
