Argentina may ban dichlorvos and trichlorfon

Argentina’s National Service of Health and Food Quality (Senasa) concluded the period of consultation for the proclamation of the resolution that bans the use of dichlorvos (2,2-chlorovinyl-dimethyl phosphate) and trichlorfon during the stages of post-harvest, manipulation, stowage, grain storage and application on facilities, deposit treatment, round-houses or empty warehouses of vehicle transport or stored tobacco.
The fundamentals of the project pointed out that there was a complaint from Japan regarding the maximum limit of dichlorvos to be used on sorghum and corn shipments. The same complaint regarding wheat came from Brazil. In fact, the sunflower oil export from Argentina to the European Union reduced because of the restriction this market imposes on the presence of dichlorvos.
The resolution was very punctilious regarding the reasons for which these two were banned, including that exporters and associations have been, in fact, requesting the measure. One of the most relevant points was that these products needed 120 days to degrade under the limits accepted by importers, while boat transportation of grain requires just more than 35 days.
When established officially, the norm will call for a ban on import, commercialization, and use of active principles dichlorvos/DDVP and trichlorfon, and the formulated products that contain them, for use in grain, including the stages of production, post-harvest, transport, manipulation, stowage, and storage, as well as the facilities for grain storage and tobacco.
As in other cases, a declaration of stocks should be done until the product is totally out of circulation, or 180 days after the norm is published in the Official Gazette. Anhui Sinotech Industrial Co.,Ltd has long provided a variety of chemical products, the main products are Agrochemical Phosphate Fertilizer,Phosphate Fertilizer and so on.

What is silicon carbide whiskers and its application

Silicon carbide whiskers are a kind of single-crystal fiber with a certain length-to-diameter ratio, which has very good high temperature resistance and high strength. It is mainly used in toughening applications where high temperature and high strength applications are required. Such as: aerospace materials, high-speed cutting tools. At present, it has a very high performance-price ratio. Silicon carbide whiskers are cubic whiskers, and diamonds belong to a crystal form. They are the whiskers with the highest hardness, the largest modulus, the highest tensile strength and the highest heat resistance temperature. It is both α-type and β-type, in which β-type performance is better than α-type and has higher hardness (Mohs hardness of 9.5 or more), better toughness and electrical conductivity, anti-wear, high temperature resistance, especially earthquake resistance Corrosion-resistant, radiation-resistant, has been applied to aircraft, missile casings and engines, high-temperature turbi...

We have already used titanium dioxide powder in our lives.

Titanium is a chemical element, chemical symbol Ti, atomic number 22, located in the fourth cycle of the chemical periodic table, group IVB. It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine gas. The most common compound of titanium is titanium dioxide, which can be used to make white pigments. In the past, people used to mine titanium ore, the main purpose is to obtain titanium dioxide. 1.The nature of titanium dioxide Titanium dioxide (chemical formula: TiO2) is a white or bulk amphoteric oxide with a molecular weight of 79.83. Titanium dioxide is a compound of titanium, a pure substance composed of two or more elements (different from elemental matter). A compound has certain properties, different from the elements or ions it contains, and other compounds. Properties of crystal form: TiO2 has three main crystal forms such as rutile type, anatase type and plate titanium type. Optical properties: Since T...

Monopotassium phosphate, MKP

Monopotassium phosphate , MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the acidity at a relatively low level. Single crystals are paraelectric at room temperature. At temperatures below −150 °C (−238 °F) they become ferroelectric. Fertilizer-grade MKP powder contains the equivalent of 52% P2O5 and 34% K2O, and is labeled NPK 0-52-34. MKP powder is often used as a nutrient source in the greenhouse trade and in hydroponics. As a crystal, MKP is noted for its non-linear optical properties. Used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). Also to be noted is KD*P, potassium dideuterium phosphat...
