[Chinese aluminum industry] Aluminum sulfate has a long history as a precipitant for rosin sizing, but it is only suitable for acidic conditions. With the rapid development of the paper industry, neutral sizing has increasingly shown its unique advantages, and has a tendency to replace acidic sizing. The neutral sizing system consisting of aluminum sulphate instead of aluminum sulphate and anion disperse rosin gum makes full use of inexpensive rosin to achieve neutral sizing without having to...
Thrombosis is a solid substance formed by the deposition, coagulation, and coagulation of blood components in the heart or part of the blood vessels of living animals. It is a small piece of blood flow formed on the surface of the blood vessels in the cardiovascular system where the blood vessels are peeled off or repaired. The incidence of thrombosis is high and even more harmful. According to statistical data, the number of deaths caused by stroke and myocardial infarction with...

Every year, China needs to import 400,000 tons-500,000 tons of chloridized titanium dioxide. Companies in various parts of the country are targeting the market gap and are ready to go. According to the existing data, it is expected that there will be one million tons of domestically-built and proposed project production capacity. Analysts pointed out that in the future, the market will probably fall into the “excess crisis”. According to statistics from the General Administration of Customs of...
[China Aluminum Industry Network] The performance and advantages of polyaluminum ferric chloride mainly include: 1. The hydrolysis rate is fast and the hydration is weak. The resulting pods are compact and have a rapid sedimentation rate. Due to the small influence of water temperature changes, it can meet the requirements of shear force generated during the flow. 2. The solid product is brown, red-brown powder and easily soluble in water. 3. Aluminum ions in the source water and residual free...
It was learned from the Shanghai Municipal Administration for Industry and Commerce that the Shanghai Municipal Administration for Industry and Commerce recently conducted quality monitoring on 38 batches of PVC insulated wire and cable sold in some building materials supermarkets, integrated markets, and professional markets. After testing, there were 10 batches of unqualified products, and the qualification rate was 73.7%, of which 3 batches were suspected of counterfeiting. It is reported...
Recently, a utility model patent—Hydrochloric Chlorine Perchlorate on-line detection device located in Jiaozuo, Henan Province, was granted a patent certificate issued by the State Intellectual Property Office. In the past, the monitoring of excessive free chlorine in the synthesis of hydrogen chloride was manually detected. The analysis time was long and the results were lagging. Continuous, timely, and comprehensive tests could not be performed, and deflagration was easily caused by chlorine....
Russian industry sources revealed that Russia’s First Deputy Prime Minister Igor Shuvalov had decided to hold a meeting recently and that since 2013 potassium chloride will be sold at market prices. 2011-2012 is a transitional period, and the price of potassium chloride will be based on the lowest export price. However, compound fertilizer producers can be compensated for the additional spending on the purchase of potassium chloride. The amount of compensation has been entrusted to the Russian...
Chlorine is the most essential plant nutrient discovered at the latest, but the impact on crop growth, yield, quality, soil and the environment has received great attention. Therefore, proper application of chlorine fertilizer during planting can enhance the quality of crops. With the rapid development and growth of the Alkali Industry, ammonium chloride and potassium chloride and other chlorinated fertilizers are increasing day by day. They are widely used in various crops. The application of...
For the use of heat energy in the synthesis of hydrogen chloride, two methods are currently used in China: one is the use of steel water jacketed hydrogen chloride synthesis furnace to produce hot water. This type of steel synthesis furnace is vulnerable to corrosion at the top and bottom of the furnace and has a short service life. The application of by-product hot water has a limited range of applications; the other is the use of graphite-based hydrogen chloride synthesis boilers that produce...
According to news from foreign media, Belgian and Dutch technicians developed the world's first miniature sensor that can simultaneously measure pH and chloride (Cl-) levels in fluids. This sensor may have better sensitivity, accuracy, and response time, and at the same time much smaller, and later may also be cheaper. Researchers at the Imec and Holst Centers (Leuven, Belgium and Eindhoven, The Netherlands) believe they have the world's first miniature sensor that can simultaneously measure pH...

As the taste fades, the haze on the potash market has not yet been dispersed. The early winter storage was not vigorous. With the start of the spring market, urea rose a bit, and a small amount of nitrogen fertilizer fluctuates. However, potassium chloride is still a bit dead. “Refreshing” seems to be only the share of hope, but how to catch it cannot catch it. . Up to now, no major progress has been made in the new major contracts. Waiting, etc., only saw the low-end CIF value of standard...
After the Spring Festival, the ammonium chloride market experienced another “plunge” since 2012. It is reported that the market price of ammonium chloride in major regions of the country fell from 600 yuan/ton to around 550 yuan/ton from January 2014, and wet ammonium From 500 yuan / ton to about 450 yuan / ton, the actual turnover of ammonium chloride in individual areas fell below 400 yuan / ton. The one-month demand gap period, together with the normal production of upstream alkali companies...
