As the name suggests, water-based cutting fluid is a liquid used for metal cutting, grinding and abrasive machining. Due to its good cooling properties, lubricating properties, anti-rust properties, degreasing and cleaning functions, anti-corrosion functions and easy dilution lubrication, most of these cutting fluids are made of various super-functional additives through scientific blending and formulation. Other characteristics, can be used to cool and lubricate tools and machined parts, is a commonly used liquid in industry. Water-based cutting fluids contain a large number of surfactants, so there are always various foam problems in use. Therefore, it is necessary to use a water-based cutting fluid defoamer. Adding it in the process of use can play a significant anti-foaming effect. Our technicians combined with many years of experience in defoaming, developed and produced aqueous cutting fluid defoamer. The defoamer is made of special modified polyether and fluorine-containing raw materials mixed by a special process, and it dissolves quickly. It can defoam and inhibit foam under high temperature, strong acid and alkali, high shear and high pressure conditions, and has many excellent properties: 1、Excellent resistance to high temperature, acid and alkali, no floating, no floating oil;. 2、It can eliminate and inhibit the foam of all kinds of bad systems in a wide temperature range. 3, it has good diffusivity and permeability, can be fully compatible with oil and cutting fluid, in acid, alkali, salt, electrolyte and hard water can play a stable role.

In the water crisis continues to erupt now, water resources have become a very precious resource, water used in all aspects of life, people's daily life has been inseparable from the water, human beings to carry out water treatment has been quite a number of years of history, the way of water treatment, including physical treatment and chemical treatment, mainly for the treatment of sewage and drinking water, and in the sewage treatment works, due to the easy generation of bubbles, it needs to be used to sewage treatment defoamer. Use to sewage treatment defoamer. The purpose of water treatment is to improve the quality of water to meet certain water quality standards. Water recycling can save water to a large extent, in the process of sewage treatment, will encounter a large number of biochemical pools produce a large number of foam, and if stationary, it will overflow from the pool, causing serious contamination of external equipment outside the pool wall, so that the operating conditions deteriorate, seriously affecting the surrounding environment. Water treatment defoamer can well control or clean up the foam generated in the process of sewage treatment, with the continuous development of the defoamer industry, sewage treatment defoamer a wide range of types of sewage treatment defoamer for different sewage there are different defoamer for sewage, such as: domestic sewage treatment defoamer, aquaculture wastewater treatment defoamer, plating wastewater treatment defoamer and so on. The recycling of water after sewage treatment meets the requirements of contemporary socio-economic development and environmental protection. Along with the water resources crisis, the process of sewage reuse has also become a point of concern, in order to improve the water quality and change the environment, the technology of sewage treatment will continue to develop and innovate.

One of the major issues facing participants in the Brazilian containerboard market at the moment is the impact of the floods in Rio Grande do Sul on demand in the country. Although difficult to estimate, especially in light of the downward revision of gross domestic product (GDP) forecasts, we still believe that the floods will have a limited impact on demand for paper products in 2024, as the negative impact should be offset by a positive outcome. The industry consensus is that Brazil's 2% GDP growth forecast could be revised down by 0.3-0.4 percentage points, as Rio Grande do Sul accounts for around 6.5% of the country's GDP, but has a higher share of industrial production (~8%) and agriculture (~13%). The federal government estimates that the state, which has a population of 10.8 million, will need about $10bn to rebuild. Several pulp and paper mills were directly or indirectly affected by the tragedy. It's worth noting that, according to estimates from economists at Valor Media Group, the average GDP of affected countries fell by about 1.5 percentage points following other similar disasters around the world. So what does this mean for paper product consumption? For ease of explanation, we will discuss this in two time frames: the short term (next 1-3 months) and the medium term (next 4-12 months). Short-term impact: more difficult to assess In the short term, it is expected that existing mills in the state will experience lower start-up rates, which will reduce production and raw material consumption. However, other mills across Brazil may be able to temporarily increase their start-up rates to offset the loss of production at the Rio Grande do Sul mill. The state is home to CMPC's Guaíba mill, which has the capacity to produce 2.3 million tonnes of pulp per year, or about 7.9% of the country's total pulp capacity. There are also at least seven household paper producers there, with annual production of 90,000 tonnes, or 3.7% of Brazil's household paper capacity; printing and writing paper production of about 77,000 tonnes per year, or about 3% of Brazil's total capacity; and boxboard capacity of about 107,000 tonnes and other industrial packaging paper capacity of about 24,000 tonnes, or 1.7% and 0.9% of the country's capacity, respectively. Thus, at first glance, the tragedy should have had little impact on the production side, regardless of the type of paper. However, the consumption of paper products by the local industry will decline as manufacturers partially or completely stop production during the disaster. The main impact on packaging paper consumption will come from containerboard, although this is largely produced out of state, and the animal protein and food industries, which have reported double-digit losses and production losses due to rationing of animal raw materials for the major beef and food industries. Exports are also expected to decline in the near term, thereby reducing packaging paper consumption. However, consumption o...

Electroplating is the process of coating a thin layer of other metals or alloys on certain metal surfaces. When it comes to electroplating, it is naturally associated with electroplating solution. It refers to a liquid that can expand the cathode current density range of metals, improve the appearance of coatings, and increase the stability of solution oxidation resistance. Through the electroplating process, products with different metal glosses can be obtained, which are more popular in the market. Therefore, the electroplating process is very important. However, in the actual process application, the electroplating process will also produce foam, which requires the use of electroplating defoamer. In production and application of electroplating, due to the excessive organic substances in the bath, too high concentration of pickling solution, too much impurities. And there is still an oxide film on the surface before entering the plating bath, the electroplating solution will produce a large number of foam. Bad consequences of too much foam： 1. It will lead to increased costs. 2. Cleaning agent has Excessive loss. 3. It will affect the quality of electroplating. 4. It will affect the normal operation of the machine. After systematic research and on-site testing, defoamer used in the electroplating solution is refined from a specially modified organic polymer, belonging to high stability products with excellent defoaming function, will not cause emulsion breaking, oil floating, oil bleaching, precipitation and other phenomena, and has no obvious impact on the production of subsequent processing.

With the rapid development of the automotive industry, the usage of automotive coating is also constantly increasing. Automotive coating mainly include primer, intermediate coat, and topcoat, among which the topcoat is further divided into natural color paint and metallic flash paint. The water-based process of automotive coating is gradually carried out from bottom to surface. At present, more than 90% of the primer has been water-based coating, and 88% of the automotive intermediate coating have also adopted water-based technology. The application of water-based metal flash primer has exceeded 65%. The successful application of water-based coating in the automotive industry mainly benefits from the following aspects: First, water-based coating is low-carbon and environmentally friendly.Compared to traditional oil-based car coating, the emission of harmful substances VOC in water-based coating is reduced by 70% compared to oil-based coatings. This is beneficial for protecting the environment and conforms to the trend of low-carbon environmental protection. Second，water-based coating itself has excellent performance. In terms of vehicle painting, water-based paint has better leveling, adhesion and wear resistance, which makes the topcoat more vivid and full, and is resistant to stone impact and scratches.Using water-based paint for touch-up paint has a similar color and luster. The functions are closer to the quality of the original factory, and more in line with the consumption needs of car owners. Third，the application of water-based coating helps to reflect the social responsibility of automobile companies and enhance their corporate image.Water-based automotive coating has good performance and is low-carbon and environmentally friendly. They can not only improve the service quality and image of automobile companies, but also have positive significance for environmental protection and help shape the image of companies assuming social responsibility. Fourth,the application of water-based coating provides a safer and healthier environment for auto painting workers. Water-based coating contains a lower proportion of harmful substances, which helps to protect the health of paint workers.

A delegation composed of South Korean experts and others inspected the first nuclear power plant on the 23rd, focusing on the treatment water discharge into the sea plan of TEPCO Fukushima Daiichi Nuclear Power Plant. The inspection plan lasts until the 24th. The inspection team confirmed the multi nuclide removal equipment (ALPS) for purifying water contaminated with radioactive substances, the equipment for measuring tritium activity in treated water, and the equipment for discharging into the sea. After his inspection on the 23rd, the Chairman of the South Korean Atomic Energy Safety Commission, Liu Guoxi, who served as the head of the delegation, gave an interview to the media and said, We have seen all the equipment we want to see. It is said that the inspection team focused on the structure of measuring the activity of radioactive substances before discharging the treated water into the sea. The delegation to Japan was agreed up at the Japan-South Korea summit meeting on the 7th. The delegation consisted of 21 experts in the fields of nuclear power and radiation, and stated that "the safety will be evaluated based on scientific evidence."

Suzano SA, the world's largest producer of hardwood pulp, is considering selling its products to China in RMB, further indicating that the US dollar is gradually losing its dominant position in the commodity market. Walter Schalka, chief executive of Suzano SA, said in a previous interview that RMB was becoming increasingly important and some customers in China were also willing to trade in RMB. Currently, the US dollar still dominates global trade settlement, the speed of switching to RMB in various commodity contracts from oil to nickel is accelerating. Schalka said he believes that the US dollar will become less important in the future, but he also pointed out that the renminbi still needs further transformation. He believes that the tense geopolitical relationship between China and the United States is the main concern of the company, as it may suppress demand and prices of pulp for a long time. According to public information, Suzano SA is the world's largest producer of hardwood pulp, headquartered in Brazil, with a share of approximately 15% in the global hardwood pulp market in 2020. China is the largest commodity buyer and also accounts for 43% of Suzano's pulp sales.  

Plasma coating was applied to the wings of metal butterflies, and it was this insect that sparked the research. Researchers at the University of Florida in the United States drew inspiration from butterfly wings to develop a new energy-saving paint that is natural and environmentally friendly.This coating is not made of pigments, but uses the nanoscale structure of colorless materials such as aluminum and aluminum oxide to produce color, making it very environmentally friendly. This alternative to pigment colorants can help save energy and slow down global warming. By arranging them at the top of the oxide coated aluminum mirror in different ways, the scattering, reflection, or absorption of light can be controlled. The rich colors of butterfly wings follow a similar principle. Debashim Chanda, University of Central Florida Nanoscience and Technology Center professor said, because the pigment gradually loses its ability to absorb photons,the normal color fades.But structural paint is not limited by this phenomenon, and once applied, it should remain for centuries. According to the scientists' calculations, it takes only 1.4 kilograms of plasma paint to cover the surface of a Boeing 747. Conventional commercial paint requires at least 454 kilograms to get the same effect.This means that it can significantly reduce the greenhouse gas emissions generated by aviation coatings. In addition, plasma coating absorbs less heat, its undersurfaces are cooler than those covered by commercial coating.     Plasma paint is light.This is due to the large area-to-thickness ratio of this coating, which achieves full coloration at a coating thickness of only 150 nanometers, making it the lightest coating in the world. The paint is still a long way from mass production.
