It is not easy to tear when stretched, because most optical glass is used in the production of stretch folding.
It is not easy to drop confetti, and even tiny confetti will not work.
It is divided into several grades according to hardness, and K3 and K4 are mainly used

310+/-10nm；400nm is the flatness of the glass. It is said that the transmittance rate is required. , I should say that it is hardness, this one is a bit vague.

It has specific requirements for optical constants, and has the characteristics of high transmittance in the visible area, no selective absorption and coloring. According to the Abbe number, it is divided into coronal and flint glass, and each type is divided into several kinds according to the refractive index, and is arranged in order according to the refractive index. It is often used as lenses, prisms, and mirrors for telescopes, microscopes, cameras, etc.
2. Anti-irradiation optical glass.
It has a large absorption capacity for high-energy irradiation, with high-lead glass and CAO-B2O2 system glass, the former can prevent radiation and X-ray irradiation, and the latter can absorb slow neutrons and thermal neutrons, which are mainly used in the nuclear industry, medical fields, etc. as shielding and peeping window materials.
3. Radiation-resistant optical glass.
Under certain rays and X-ray irradiation, the transmittance of the visible area changes less, and the varieties and grades are the same as those of colorless optical glass, which are used to manufacture optical instruments and peep windows under high-energy irradiation.
4. Colored optical glass.

Anonymous users2024-02-051. Chemical bonding: The chemical bonding method uses 100% wood pulp fiber (fluff pulp) as raw material, and the fibers that are opened into a single fiber state are screened by airflow, and the water-soluble adhesive is sprayed on the surface of the fiber web by spraying, and then baked and strengthened into cloth.
The main uses of the products are industrial wipes, feminine hygiene products, baby wipes, tablecloths, wet wipes and cooking cloths.
2. Thermal bonding: Thermal bonding is to mix hot melt fibers into fluff pulp fibers, and the mixing ratio is generally not less than 15%, after being webbed by airflow, the low melting point fibers in the fiber web are melted through hot air or hot rolling to strengthen the fiber web into cloth.
Thermoadhesive nonwovens are mainly used as absorbent cores for highly absorbent hygiene products, thin women's sanitary napkins, etc., because they do not contain chemical adhesives, fluffiness and hygroscopicity.
For this purpose, some production lines are equipped with a device for applying highly absorbent resin (SAP) powder.
Due to the addition of polymer water-absorbing resin, water can be turned into a solid after water absorption, which greatly improves its water absorption capacity.
Workflow for glass beads.
1) Check the forward and reverse rotation of the motor. (2) Open the air inlet of the furnace body, start the induced draft fan, evacuate the residual gas of the furnace body, start the circulating water pump after five minutes, and wait until the sewer pipe of the furnace body flows smoothly, and then prepare for ignition. (3) Open a musket. >>>More
1- Ultra-clear float glass: Ultra-clear glass is a kind of ultra-transparent low-iron glass, also known as low-iron glass and high-transparency glass. It is a high-quality, multi-functional new high-grade glass variety, with light transmittance of more than above, with crystal clear, high-grade and elegant characteristics, and is known as the "crystal prince" of the glass family. >>>More
