raw material

Including main raw materials and auxiliary raw materials. The former refers to the introduction of raw materials such as the oxides that form the network structure of the glass, the intermediate oxides and the oxides outside the network; the latter can accelerate the melting of the glass or make it obtain certain necessary properties.

Outstanding thermal shock and chemical stability
Drawn tube and bar products are manufactured using the latest technology to produce pristine surfaces that are smooth, non-porous, fully transparent and corrosion-resistant.
Borosilicate glass tubes, rods, profiles and capillaries are used in the production of laboratory glassware, glass fiber optic ferrules, NMR tubes, IVF pipettes, gas chromatographs, industrial instruments, process piping, solar thermal collectors and lamps.

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

Borosilicate glass has a longer service life at temperatures exceeding 100°C, and its electrical resistance exceeds that of many metals and other materials. Borosilicate glass has a longer service life at temperatures exceeding 100°C, and its electrical resistance exceeds that of many metals and other materials. However, borosilicate glasses also have their limitations. They are not resistant to hydrofluoric acid, concentrated phosphoric acid, and strong bases, especially at high temperatures (>100°C). "Glass corrosion occurs, the glass surface wear.

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

Batch preparation

First of all, 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 should be 0.25 ~ 0.5 mm. Particles that are too coarse are not easy to melt sufficiently, and the remaining powder forms stones or silica-rich nodules in the glass; Particles that are too fine tend to disperse or aggregate. The raw material is precisely weighed according to a certain formula according to the particle size, and then mixed with a drum, stirring paddle, or disc.
Molten glass is batch melted and refined to form uniform, bubble-free, rock-free molten glass at high temperatures. The melting temperature of glass batching varies with the composition, usually between 1300 and 1600°C. The batch undergoes a series of physicochemical reactions that gradually melt completely at high temperatures. With the increase of temperature, the viscosity decreases obviously, and a large amount of gas and raw air escape, in which the melt decomposes and clarifies. The chemical composition of molten glass tends to be uniform when bubbles are removed at high temperature. Use mechanical stirring if necessary. Upon completion of clarification and uniform cooling, the glass uniformly reaches the desired viscosity suitable for molding.
