The impact of the COVID-19 on the global economy and how will paper industry going? Covid-19 is still in the stage of global spread As of the evening of May 2, according to relevant statistics of the International Health Organization, there have been more than 3.27 million cases of new coronary pneumonia diagnosed globally, including a total of 230,000 deaths. The United States currently has the most confirmed cases of infection, with a cumulative total of more than 1.06 million cases. The total cumulative cases in Europe are more than 1.49 million cases, of which Spain, Italy and the United Kingdom have cumulative cases of 210,000, 200,000 and 170,000 cases, the three countries with the largest number of infections in Europe. The number of newly confirmed cases per day in Spain and Italy has shown a slowing trend. Brazil is the country with the largest cumulative number of confirmed cases in Latin America, reaching 85,000 cases, exceeding the current cumulative number of confirmed...

Is silicone oil safe? From a physiological point of view, polysiloxane is one of the polymers with the lowest known activity. The results of toxicological studies suggest that dimethyl silicone oil, which removes low-boiling substances, is non-toxic and can be used in large amounts in food, cosmetics, and pharmaceuticals. The LD50 value (50% lethal amount) of the lethal dose of dimethyl silicone oil is more than 35g/Kg. This value is classified according to the toxicity of the American Industrial Hygiene Association, which is equivalent to non-toxic; it also has no chronic poisoning problems and will not be absorbed by the digestive system. No irritation to the membrane; low viscosity dimethyl silicone oil has slight irritation to the cornea, but no harm. Safety data of silicone oil as follow: Types of silicone oil Viscosity (25 °C /mm 2 Ÿ s) Skin irritation (human) Chronic toxicity (rat, 6 ...

The global papermaking chemicals market will exceed 42 billion US dollars in 2025 Relevant data show that the global papermaking chemicals market will exceed 42 billion US dollars in 2025. Papermaking chemicals as follow: process chemicals, functional chemicals, pulping chemicals on the other hand by type, they can be divided into special chemicals, commodity chemicals, etc. Papermaking chemicals are specifically used to change paper properties, including color, strength, recycling performance, basis weight, quality, and related attributes. In order to obtain specific functions, the paper undergoes various processes such as bleaching, beating, strengthening and sizing. In order to further improve paper quality and improve multiple functions, people in the industry continue to improve the performance of paper, and it is expected that the scale of the chemical industry will be further promoted in the next few years. Why does paper chemicals has been increasing? As the pursuit of paper fi...

How should we select defoamers / antifoams for paper pulp? Pulp and paper antifoaming agents is very necessary in papermaking, because a lot of foam will be generated in the process of papermaking and pulping, the surface tension of the generated saponification is less than the surface tension of black liquor produced by cooking materials, making it It exists in the surface layer of black liquor and forms a thin film, which forms foam under the mixing action of air. The papermaking process is mainly divided into two major steps,  Washing pulp Papermaking No matter which step inevitably produces foam, so you need to use defoamers/antifoam for paper industry, there are many types of defoamers, the following is for everyone Introduce the characteristics of papermaking defoamers. Excessive foaming will result in the loss of fibers and raw materials. Further, the presence of air in the wet paper web can affect the filtration rate of paper in the paper making pulp defoamers is a better s...

Invely-3180 defoamer for paper pulp（black liquor） It is well known that pulping is the process of separating fiber materials from plants to obtain pulp. In the pulping process, a large amount of foam will be produced, affecting the production efficiency and the quality of the pulp board. The role of defoamers in the pulp industry is very critical. It is used to prevent various problems caused by foam during the pulp washing process, such as slurry overflow tank, reducing the efficiency of the pump, the formation of deposits on the paper, pulp water filtration Problems, etc. Invely defoamer 3180 uses innovative silicone chemistry to achieve superior foam suppression. It can be used in black liquor without depositing on paper, improving water filtration performance and effectively helping pul p mills Improve efficiency. Invely-3180 improves production efficiency while reducing total operating costs. Invely-3180 is specially designed for pulp and is also recommended for industrial cleanin...

Why should use defoamer for liquid detergent? Detergent is a new laundry detergent after detergent and soap. I believe many people have misunderstood laundry detergent. They think that the foam in laundry detergent is getting better and better. Actually it is not, whether it is laundry detergent or detergent. It is not to determine the cleaning ability by looking at the amount of foam, and too much foam, not only clothes are difficult to clean, but the foam that is discharged is also difficult to be decomposed by nature, so the laundry liquid produced by general manufacturers will use laundry liquid defoamer. The difference between laundry detergent and washing powder: ²   The surface active ionic components are different, the laundry detergent is non-ionic, and the laundry powder is anionic surfactant ²   The PH value is different. The laundry detergent is neutral, while the detergent is alkaline. Foam introduction of laundry liquid: The cleaning ability of the ...

2018 Silicone Oil Price Trend Silicone prices skyrocket At the beginning of 2018, silicones continued to upgrade with an unstoppable rise. In the second quarter, they rose to the highest price in the past eight years. The whole industry is in full swing and the scenery is infinite. Individual enterprises, silicone oil, 107 rubber, raw Glues, rubber compounds,and cracking materials companies are all full of pots. There are several factors in the skyrocketing factors: First： There is no new capacity in the installation, everyone is happy to watch the 2018 market all the year; Second： The overseas demand is strong, the export market continues to be good; Third： The high market, prompting all the upstream and downstream personnel to enter the bargains Mode, hope to share a piece of this good market. The phenomenon of foaming has gradually become prominent in the rapid rise in prices. Silicone prices plummeted After July 2018, the domestic silicone market began to show a ration...

As we all know, compared with the developed paper-making countries in Europe and America, due to the shortage of land resources in China, especially the shortage of forest resources, we must protect limited forest resources. Therefore, the urgent issue that chinese paper industry must be face is : how to use artificial fast-growing forests to produce short fibers and recycled fiber/waste paper, by the way, using fine chemicals can help paper workers effectively alleviate and solve this problem. So here let us learn what exactly is fine chemicals? Fine chemicals mainly refer to chemicals used in the wet-end flow system of paper machines. Everyone knows that the wet end of the paper machine is a study of the various materials in the paper stock (slurry circuit and slurry circuit) in the process of water filtration, retention, forming and white water circulation, water, fiber and other additives. The science of interaction and action law; it is also a science to study the interaction...
