The working principle of double-layer glass reactor:
Double-layer glass reactor is a commonly used laboratory instrument, which is widely used in modern fine chemical, biopharmaceutical, scientific research, and experiment industries. It can be used for concentration, distillation, back distillation, and separation under constant speed, constant force, and constant temperature conditions. , Purification reaction, is an ideal equipment for teaching, experiment, pilot test, and production. The product can be combined with circulating water vacuum pumps, diaphragm vacuum pumps, low temperature circulating pumps, circulating coolers, high-temperature constant temperature circulators, low temperature cooling liquid circulating pumps, closed refrigeration and heating circulation devices (also known as high and low-temperature circulation devices) and other supporting system devices.
Why should the double-layer glass reactor be made of high borosilicate glass?
The double-layer glass reactor uses 3.3 high borosilicate glass (GG-17 glass) as the raw material. Its surface is smooth, clear, and transparent. It has good physical and chemical properties and anti-corrosion functions. The mechanical strength, compressive strength, and impact force of the finished product are all Meet the requirements of anti-corrosion technology for chemical equipment. Its chemical stability is better than any other known materials, and it is very stable in water, acids, salt-soluble substances, organic matter, and halogens such as chlorine and bromine.
The performance of GG-17 glass is in full compliance with ISO3583. It is high borosilicate glass with good physical and chemical properties; due to its low thermal expansion coefficient, it can better withstand higher temperature differences and has good flame processing performance. It is an excellent material for manufacturing heating vessels and various glass instruments with complex structures.
The physical and chemical properties of the glass reactor are as follows:
Silicon content above 80%; processing temperature 1220℃; strain temperature 520℃; linear expansion coefficient (0～300℃) 3.3*10-6k-1; annealing temperature 560℃; water resistance level 1; softening temperature 820℃ Emergency temperature change (glass method) 300℃.
If the instrument made of GG-17 glass needs to be heated and pressurized for a long time, its safe operating temperature should not exceed the strain temperature (520℃). When it is heated to the annealing temperature, it is not easy to deform. If it is placed on a suitable support and the internal pressure is not applied, it can be heated to 600°C in a short time. In this case, the instrument should be cooled slowly to reduce The degree of stress generated.
