When the temperature drops to 2.18K, the properties of liquid helium will change suddenly, the viscosity is very small, and it becomes a super fluid that can flow upwards along the wall of the container. The thermal conductivity is 800 times that of copper. It becomes a thermal conductor with excellent thermal conductivity. Its specific heat capacity, surface tension, and compressibility are all abnormal. This abnormal liquid is called liquid helium II, and the normal liquid helium is called liquid helium I.

TDI is the abbreviation of toluene diisocyanate. TDI is a polycyanate widely used in industrial production. It is a polyurethane material and an important basic material. Mainly used to make flexible polyurethane foam, polyurethane elastomer, coatings, adhesives, etc.
TDI (toluene diisocyanate) is one of the commonly used polyisocyanate, and polyisocyanate is an important base material of polyurethane (PU). The TDI commonly used in the polyurethane industry is a mixture of 2,4-TDI and 2,6-TDI isomers, including three commonly used grades.
Sulfonated cobalt phthalocyanine is an effective catalyst for removing mercaptan in light oil. Gasoline containing sour crude oil has a relatively high sulfur content.
This product is a white powder with strong hygroscopicity. It is prone to deliquesce when exposed to the air and absorbs carbon dioxide to generate potassium carbonate.
The principle of photocatalysis is based on the oxidation-discount capacity of photocatalysts beneath mild conditions, which can reap the purpose of purification of pollution, cloth synthesis and transformation. usually, the photocatalytic oxidation response makes use of a semiconductor as a catalyst and mild as an power source to degrade organic rely into carbon dioxide and water.
Meta-xylene is an organic compound with a molecular formula of C8H10 and a molecular weight of 106. It is a colorless and transparent liquid with an odor similar to toluene. It is insoluble in water, but miscible in most organic solvents such as ethanol, ether and chloroform. Used as solvent, medicine, dye intermediate, perfume, etc.
According to the data, the domestic xylene market price trend has fallen sharply.The Pengzhou Petrochemical Plant, Urumqi Petrochemical Plant, and Fuhai Chuang Aromatics Plant each run one line. Hengli Petrochemical’s PX plant is overhauled, and other plants are temporarily The operation is stable.
Toluene diisocyanate is combustible in case of open flame and high heat. It can react with oxidants. Reacts violently with amines, alcohols, alkalis and warm water, and can cause combustion or explosion.
