Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.

Anchor rod main use and composition of the anchor must have factorsTwist anchor rod is mainly used in mine roadway, railroad, slope and tunnel projects, the main reinforcement of the dam, its role is mainly to ensure the stability of the mine roadway and underground engineering surrounding rock.

Application of Mining AnchorMining anchor rod is a tool applied to support the surrounding rock of mine roadway and underground project, which can ensure the stability of the surrounding rock of mine roadway and underground project.Mining anchor rod use scope, can realize end anchor, lengthening anchor and ** anchor; easy to operate, low price and other advantages, widely used in coal mines, railroads, hydropower and other projects all kinds of roadway support.Anchor is the basic component of tunnel support in contemporary coal mines, he will be the roadway rock reinforcement together, so that

Anchor rods are a type of support equipment commonly used in civil engineering and mining projects to enhance the stability and safety of underground structures. Here are some key points about the development trend of anchor rods:Advances in material technology: with the continuous development of material technology, the application of new materials is changing the performance and reliability of anchor rods.

Preventing Heat Stroke and Keeping Production in Ruiyu CompanySince entering August, the persistent sultry hot weather has brought a lot of unfavorable conditions to the production.
