Borosilicate Glass Tubing Acidic Oxide Raw Materials

raw material

Including main raw materials and auxiliary raw materials. The former refers to the introduction of raw materials such as oxide, intermediate oxide and outer oxide of the glass network structure. The latter can accelerate the melting of glass or enable it to obtain certain necessary properties.

Excellent thermal shock and chemical stability
The tube and rod products are produced with the latest technology, with smooth surface, no hole, full transparency and corrosion resistance.
Borosilicate glass tubes, rods, profiles and capillary tubes are used in the production of laboratory glassware, fiberglass fiber cassettes, nuclear magnetic resonance tubes, in vitro fertilization pipettes, gas chromatographs, industrial instruments, process pipes, solar collectors and lamps.

ACI not only offers replacement glass cylinders and their own tube - mirrors and level gauges, but also supplies components for glass tubes, glass cylinders and DURAN® borosilicate glass 3.3 as well as SIMAX® glass tubes.

Boron silicate glass at more than 100 ° C temperature has a longer service life, its resistance than many metals and other materials. Borosilicate glass has a longer service life at temperatures over 100°C and its resistance exceeds that of many metals and other materials. The borosilicate glass has its limits, however. They are intolerant to hydrofluoric acid, concentrated phosphoric acid and strong bases, especially at high temperatures (> -100 °C). "Glass corrosion occurs

s, the glass surface wear.

It mainly includes the steps of batch preparation, melting, forming, annealing and post-processing.

Batch preparation

Firstly, the pretreatment of raw materials includes the crushing of bulk materials, the drying of pre-wet materials and the treatment of iron-containing materials except iron. The particle size after crushing is 0.25 ~ 0.5 mm. Too coarse particles are not easy to melt, fully formed in the residual powder on the glass stone or nodules that are rich in silicon; Particles that are too fine tend to disperse or aggregate. The raw material is accurately weighed according to a certain formula according to the particle size, and then mixed with a drum, paddle or disc.
Molten glass is a uniform, bubble-free, rock-free molten glass, which is refined by melting in batches at high temperature. The melting temperature of the glass of which it is composed varies depending on the composition, usually between 1300 and 1600 ° C. This batch process undergoes a series of physical and chemical reactions, gradually melting completely at high temperatures. With the increase of temperature, the viscosity decreases significantly, and a large number of gases and original air escape, in which melting decomposition clarified. At high temperature, the chemical composition of molten glass tends to be uniform except for bubbles. Use mechanical stirring if necessary. After clarification and uniform cooling, the glass uniformly reaches the required viscosity before it is suitable for molding.
