Coal Mining Industry Special Nitrogen Making Machine

Nitrogen Gas Fire Extinguishing Principle:
Nitrogen injection goaf oxidation zone within the essence of fire prevention is to infuse a flow of nitrogen or fire area and the oxygen levels fall below 7% or 3%, to achieve the purpose of fire prevention, its role is to eliminate the gas explosion danger; Avoid the natural heat and spontaneous combustion of coal; Reduce the intensity of combustion, prevent the airtight air leakage.
Nitrogen Generator Equipment Characteristics:
1. The patent process, compared with the same purity and flow rate of nitrogen, equipment to reduce energy consumption of 15-20%.
2. Adopt humanized man-machine interface, intelligent control, nitrogen production button.
3. The unique carbon molecular sieve compaction technology, high efficiency, long life; Installation is simple, no special foundations, leveling the ground; High reliability, low operation cost.
4. Low maintenance costs, on-site service, quick and thoughtful.
Underground coal mines with carbon molecular sieve nitrogen making machine (mobile) features:
1. Can be directly used in the coal mine gas or gas outburst place.
2. Reduce the needed for the underground gas pipeline from the ground, reduce the pressure loss of long pipes to reduce due to loss of a gas pipeline leak and.
3. Adopt humanized man-machine interface, intelligent control, simple operation.
4. Equipment fixed on the flat car is only 0.375 m high, mobile convenience.
5. Complete and reliable protection device to ensure foolproof.
6. High reliability, low running cost, low maintenance cost.

4A molecular sieve

4A molecular sieve is an alkali metal aluminosilicate, which can adsorb water, NH3, H2S, sulfur dioxide, carbon dioxide, C2H5OH, C2H6, C2H4 and other critical molecular diameter of not more than 4A. Widely used in gas, liquid drying, can also be used for some gas or liquid purification and purification, such as the preparation of argon.

Porous materials have been widely used in many fields, such as microporous 4a molecular sieves as the main catalytic materials, adsorptive separation materials and ion exchange materials, and play an increasingly important role in petroleum processing, petrochemical, fine chemical and daily chemical industry. .

Molecular sieve 4a (also known as synthetic zeolite) is an aluminosilicate microporous crystal. It is composed of silicon oxide, aluminum oxide tetrahedron basic skeleton structure, there are metal cations in the lattice (such as Na +, K +, Ca2 +, Li +, etc.) to balance the excess negative charge in the crystal. The type of molecular sieve according to its crystal structure is divided into: A type, X type, Y type.

Application of crankcase vent hose

In the engine work, there is always a part of the combustible mixture and exhaust gas through the piston ring to the crankcase vent hose, the gasoline inside the crankcase to condense the oil will dilute, performance deterioration. Exhaust gas containing water vapor and sulfur dioxide, water vapor condensation in the oil to form foam, damage to oil supply, this phenomenon is particularly serious in the winter; sulfur dioxide water to produce sulfurous acid, sulfurous acid encountered in the air to produce sulfuric acid, these acidic substances The emergence of oil not only metamorphic, but also make parts subject to corrosion. As the combustible mixture and exhaust gas to the crankcase, the crankcase vent hose pressure will increase, the oil from the crankshaft oil seal, crankcase liner, etc. seepage and loss. The loss of oil vapor to the atmosphere will increase the engine of atmospheric pollution. Engine crankcase ventilation device can be avoided or mitigate the above phenomenon, therefore, the engine crankcase vent hose ventilation role is:

1. To prevent oil deterioration:
2. To prevent crankshaft oil seal, crankcase liner leakage;
3. To prevent all kinds of oil vapor pollution of the atmosphere.

Secure Plate Sealing with Easy Sample Access

Aluminium foil plate seals are an ideal solution for securely sealing samples within plate wells, whilst they can be readily pierced with automated or manually-operated pipette tips for easy sample access as required.
Enabling individual well access, eliminates the potential for aerosols and cross-contamination that can result when removing other types of plate-sealing lids.
AlumaSeal foil seals, from Alpha Laboratories, exhibit extreme temperature tolerance, protecting samples down to -80ºC and up to 120ºC. They provide excellent barrier properties with virtually no sample evaporation or drying. Certified DNase-, RNase-, and nucleic-acid-free they ensure no sample contamination or assay interference.

AlumaSeal 96™ is sized to fit inside the rim of raised-rim PCR plates. It has a partial width end-tab for easy removal. AlumaSeal 384™ can be used with any 384 or 96 well plate that doesn’t have a raised edge and it has a single full width end-tab. They consist of 38 μm thick aluminium foil with 38 μm layer of acrylic adhesive

AlumaSeal II™ is a 36 μm soft non-permeable aluminium foil sealing film with a 28μm layer of strong medical-grade acrylic adhesive. It is ideal for PCR and cold storage. Each sealing film measures 82.6 x 146.1mm and offers sufficient sealing area for all PCR plates. Compared to other aluminium foils, AlumaSeal II has less tendency to roll back on itself when removing the backing paper and conforms well to the plate during application. It eliminates the need for heat-sealing devices or mats.
