Building materials industry structure will be optimized and upgraded
In granite mines, only injection-molded and
rubber-injected diamond beaded ropes with or without springs can be used.
Diamond beads can be sintered or electroplated, but sintered is mainly used.
Generally, there are 32-40 diamond beads per meter. It is suitable for
secondary cutting at the initial stage of mining and any angle, but not for
block shaping. The largest cutting side reaches 20-500㎡, rarely 300-450㎡, the average production
capacity is 1.5㎡/hour-8㎡/hour, the life of diamond beaded rope is 2.5㎡/meter-12㎡/meter on average, diamond The
linear speed of the beaded rope is 16-26m/s.

To this end, the Ministry of Industry and Information Technology will gradually compile and publish a catalogue of green building materials, guide the development of green building materials, and support the construction of green buildings. In addition, we must pay attention to the link between production and use, accelerate the revision of existing standards and norms that are not conducive to the promotion of green products, and adopt advanced standards. Regulate and incentivize the technological progress of green building materials, speed up industrial development and transformation and upgrading.
Zhang Qiong, a business and building materials industry analyst, said that the country’s proposed green building program has provided tremendous opportunities for related industries. With the increase in market demand, the structure of the building materials industry will be optimized and upgraded, and relevant companies will gradually increase their production levels.
