As we all know, condensing pipes are experimental devices that are used to promote condensation, and generally consist of two glass tubes, one inside and one outside. One of the smaller glass tubes penetrates the larger glass tube. It is understood that it is a glass instrument that uses the exchange principle to condense condensed fresh gases into liquids. So, what are the types of condensers? In fact, knowing some common sense about condensing tubes can not only increase our knowledge, but also solve some of the problems in life! Let's take a closer look at the types of condensing tubes . !
Reflux condenser
When the liquid reactant is easily volatilized, in order to avoid the consumption of reactants and to fully use the raw material, a condensation reflux device of the device design must be generated so that the substance can be recovered from the gaseous state after condensation, thus achieving the effect of reflux and collection. It is understood that labs can install long glass tubes or condensate return tubes at the time of installation.
2. Straight condenser
The straight condensing tube is composed of a combination of straight glass inside and outside, and is generally used for distillation operation, but the distillation temperature must not be higher than 140 degrees, and at the same time, it cannot be refluxed. There are connection fittings on the upper and lower sides of the outer tube, which serve as inlets and outlets. The specific method of operation is to connect the plastic pipe at the lower end to the faucet and use it as the water inlet. Because the water temperature at the inlet is not high, but the water heated by the steam, the water temperature is higher. The hotter water, because of its low density, eventually causes the temperature to rise automatically, so it helps the circulation of the cooling water.
3. Air condensation tube
Both the air condenser and the straight condensate are used when distilling off the product (including distillation and fractionation). When the distillation boiling point exceeds 140 degrees Celsius, an air condenser can be used. Its main purpose is to avoid condensation. The water cooling of the pipe leads to a large temperature difference between glass and burst.
4. Spherical condenser
Inside the spherical condensation tube is connected by a plurality of glass balls, which can help the preparation of the reflux, more suitable for reflux of various boiling points. When you use a spherical condenser for a long time, the rust in the casing can be washed away with hydrochloric acid. However, its disadvantage is that the condensed liquid is very easy to get stuck in the glass ball after solidification. Because the inlet water pressure is relatively high, it is easy to cause the hose to fall off, so when it is used, it should be tied with wire.
Conclusion of the article: What are the types of condensers ? I believe that after reading the above, everyone knows what they think! In fact, different types of condensers have different ranges of use, and their prices are also very different. Therefore, everyone should find the type of condenser they need to buy based on their own needs.
At present, waterproof roof coating and Bridge Deck Waterproofing mostly use a combination of polyurethane waterproof coating and waterproofing membrane. Although it can achieve a certain waterproof effect, there are still many problems.
UMS-AUPT polyurea elastomer waterproof coating replaces other traditional waterproof layer, not only solves the problem of poor adhesion between polyurethane waterproof coating and waterproofing membrane, lap joint between coils, sealing of waterproof coating and long construction period And technical problems such as environmental pollution caused by waterproof coatings during construction.
The Roof Waterproof Coating and bridge preservation waterproof. And UMS-AUPT brushed polyurea waterproof coating system can be used to complete the durable waterproofing easily and efficiently.
UMS-AUPT polyurea elastomer waterproof coating has excellent performance:
1. It has strong adhesion, can be attached to almost any substrate and is easy to apply. It can be used on different substrates such as concrete, metal, wood and plastic.
2. UMS-AUPT brushed polyurea elastomer jointless coating system for Waterproof Roof , the tensile strength is large, and the most chaotic parts such as roof margin, skylight and air conditioning well can also be used.
3. The construction speed is fast, the whole waterproof layer can be integrated into one body, completely preventing the immersion of harmful media, and greatly prolonging the service life of the concrete structure.
4. It has good weather resistance, excellent UV resistance, high process tolerance in outdoor low temperature environment, and can close concrete cracks up to 10 mm.
5. Good environmental adaptability, no VOS emission during construction, and solve technical problems such as environmental pollution during construction.
The two majestic constructions of Astana, the new capital of the Republic of Kazakhstan, are excellent, for example, including the largest mosque in Central Asia. This magnificent building can accommodate more than 5,000 people in the main hall, the dome is 40 meters high, and there are four minarets. Polyurea Roof Coating, which can taste the cold test of minus 50 °C.
A similar solution was chosen for the opening and closing of the Astana Stadium. The stadium covers an area of 10,000 square meters and can accommodate more than 30,000 spectators. The two special construction projects are intended to be a complete success, and it is abundantly proven that polyurea coatings can remain stable even under extreme climatic conditions, and this coating system will continue to open up new uses.
