Arm vibration caused by long-term hand-transmitted vibration operation was listed as one of the statutory occupational diseases in China in 1957, also known as local vibration disease, and is usually characterized by paroxysmal white fingers.
Hand-held power tools, especially those with unbalanced mass rotating parts, such as tools with crank-link piston impact devices and tools with eccentric devices (such as electric hammers, electric picks, etc.) Larger vibrations. When operating these tools, vibrations are transmitted to the operator's hands, wrists, and shoulders. With the wide application of power tools, the vibration hazard generated by them has attracted more and more attention.
Common measures for occupational disease prevention include: carefully maintaining and maintaining the tool in accordance with the manufacturer's instructions; when using different tools, use as low a vibration as possible; prevent the tool from being in the operator's hand Produce cold gases and liquids around; if possible, heat the handle of the tool in cold conditions; avoid using tools with high pressure on the skin in the contact area of ​​the contact area; when it is optional, choose Tools that require minimum contact pressure (grip and feed); use vibration-damping gloves; wear gloves when handling to avoid hearing damage.
There are 2 kinds of printed glass, silk screen printed Tempered Glass, and digital printed tempered glass.
Silkscreen printed glass is a special kind of decorative glass made by printing a layer of ceramic ink on the surface of glass through the screen mesh for tempering or heat-strengthening process after. As a result silk-screen printed glass is durable, scratch-proof, solar shading and with anti-glare effect. Mainly one color wholly covered printed or with design printed.
As for Digital Printed Glass, Designs can be implemented in previously unattainable dimensions, with incomparable resolution and focal precision, and with unique color intensity. The end product, refined in this way, not only meets the most challenging aesthetic demands but also satisfies on a sustainable basis all functional and material requirements. Digital printing technology is ideally suited for implementing glass designs quickly, easily, and economically - both for interiors and exteriors. Glass areas can be enhanced with high-level resolution and brilliant color intensity - according exactly to customer specifications and taste. Ceramic digital printing - unlike conventional screen printing - can print a number of different colors simultaneously.
