The 2-amino-5-nitrothiazole properties are a colorless liquid. It has a very unpleasant smell. It can be miscible with ethanol and ether and easily soluble in water. The relative density (d154) is 0.950. Melting point -70℃. Boiling point 128 ~ 129℃. Refractive index (n20D)1.501. Flash point 29.4℃. Flammable. Vapor can form an explosive mixture with air, with an explosion limit of 1.4% to 8.6% (by volume). Low toxicity, median lethal dose (rat, oral)790mg/kg. It's irritating.
Emergency treatment of leakage
Quickly evacuate contaminated areas to safe areas, and quarantine, strictly restrict access. Turn off the heat. Emergency personnel are advised to wear self-contained positive pressure breathing apparatus and protective clothing. Do not touch spills directly. Cut off the source of leakage as much as possible. Prevent water from entering restricted Spaces such as sewers and flood drains.
Small leakage: absorbed by sand, vermiculite or other inert material. They are collected and transported to open areas for burial, evaporation or incineration.
Large leakage: pyridine manufacturers are introduced to receive dikes or pits. Cover with foam to reduce steam hazards. Transfer to tank truck or special collector with explosion-proof pump for recycling or transport to waste disposal site.
Operation, disposal and storage
Operation precautions: closed operation, pay attention to ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear a filter gas mask (half mask), chemical safety glasses, rubber protective clothing, and rubber oil-proof gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid exposure to oxidants and acids. Loading and unloading should be done lightly to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may contain harmful residues.
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Warehouse temperature does not exceed 37℃. Keep the container sealed. Should be stored separately from oxidizer and acid, do not mix. Use explosion-proof lighting and ventilation facilities. Do not use mechanical equipment and tools that cause sparks. The storage area shall be equipped with emergency leakage treatment equipment and appropriate storage materials.

The operating mechanism of a dust extraction arm supplier is that dust particles are filtered after the dust-containing gas is filtered through the filtering data. The coarse dust collected by the filtering data mainly depends on the effect of inertia bumping, while the fine dust collected mainly depends on the effect of dispersion and screening. The dust layer of filter material also has filtering effect. With the accumulation of dust on the surface of the filter material, the power and resistance of the dust extraction arm supplier will increase accordingly. When the pressure difference between the two sides of the filter material is very large, some fine dust particles attached to the filter material will be kneaded to reduce the power of the dust extraction arm supplier.
How does a dust extraction arm supplier deal with hot and humid gases? Below, give you a detailed introduction:
1. The dust removal function of the dust collector producing paste bag fails, the resistance is too large, and the operation condition is good. To prevent the dust extraction arm supplier from forming dew paste bags, it is necessary to keep the body temperature 25~35℃ above its dew point.
2. When the dust collector is used to deal with high temperature and high humidity gas, a temperature detection and alarm device shall be installed at the entrance for monitoring, and rock wool and other insulation materials shall be installed outside the shell for insulation.
3. The dust collector should be strictly sealed and the air leakage rate should be less than 3%. Welding quality is important during equipment installation. All welding shall be carried out in accordance with the corresponding codes and standards. After welding, kerosene and phosphor shall be used for leakage inspection, and the air leakage shall be re-welded.
4. When a dust extraction arm supplier deals with high temperature and humidity gas, if the gas temperature is lower than the dew point during operation, the water vapor will condense and make the filter bag damp. A large amount of dust will adhere to the surface of the filter bag and block the pores of the filter bag.
V. The dust extraction arm supplier usually works under negative pressure. If the equipment leaks, it will inhale a large amount of external air and rain, which will cause the filter bag to be damp and harden and increase the operation resistance.
Six, before the dust removal system stops running, it is necessary to discharge all the wet gas in the dust collector and replace it with dry air to prevent condensation. That is to say, after the production equipment stops running, the dust removal fan should be extended for a period of time before stopping.
The dust extraction arm supplier's compressed air device includes gas tank, air compressor station, pneumatic triplet of pipeline, etc. For the dust extraction arm supplier, there is also air separator, spray pipe, etc. The dust extraction arm supplier's dust removal power source comes from compressed air. The compressed air equipment usually uses oil-free compressors or ordinary compressors for refueling and dehydrating. However, in order to determine the quality of the compressed air, the design of the compressed air station should be as close to the dust collector as possible to avoid condensation in the pipeline. In addition, compressed air station is used as far as possible to determine the stability of compressed air pressure for large pulse precipitator.
If it is not possible to design the air compressor station or the air compressor station is not near the dust collector, the compressed air tank should be set near the dust collector equipment, so that the pressure of the compressed air source can be stable. On the other hand, the condensed water generated on the compressed air pipeline can also be discharged regularly through the valve at the bottom of the compressed air tank, so as to determine the quality of the ash source of the pulse dust collector.
dust extraction arm supplier is suitable for all kinds of vertical dust generation points, flexible and convenient, local dust collection, local treatment, can achieve air cleanliness. The basic structure is composed of dust removal box, centrifugal fan, filter bag (filter cylinder), dust collector and microcomputer controller, etc. The dust is sucked into the dust collector box by the negative pressure of the fan through the suction pipe, and the coarse dust is initially filtered by the filter and directly drops to the dust collector by gravity. The fine dust is captured by the filter on the outer surface. The clean gas flows into the clean room after filtration, decomposition and purification through the filter element, and is discharged from the outlet by the fan.
