What are the processing technology of Shandong white hemp stone

Shandong white hemp is a high-quality granite, because of its bright color, hard texture, wear-resistant and corrosion-resistant features, widely used in building decoration, floor paving, countertop production and other fields. In order to give full play to the performance and aesthetic effect of Shandong white hemp stone, its processing needs to go through a number of steps, including mining, cutting, grinding, polishing, carving, protection and so on. The following is the main processing technology of Shandong white stone:

1. Mining process Shandong white stone mining is the first step in processing, usually using mechanical mining. Mining process requires attention to the following points: - site selection and exploration: before mining, the need for geological exploration of the mining area to determine the distribution of stone, quality and reserves. -Blasting and cutting: use professional cutting equipment (such as diamond rope saws, disc saws, etc.) to cut, to avoid damage to the stone. -Transportation and storage: the mined stone needs to be properly transported to the processing plant, and prevent collision and pollution during storage.

2. Cutting process cutting is the key step to process the large stone into the required size and shape. Commonly used cutting methods include: - bridge cutting: the use of bridge cutting machine will be cut into slabs or blocks, suitable for mass production. -Circular Saw Cutting: Used to cut thicker stone with high precision and efficiency. -Waterjet cutting: suitable for cutting complex shapes, smooth cutting surface and no dust pollution. Cutting parameters need to be adjusted according to the texture and hardness of the stone to ensure that the cutting surface is smooth and crack-free.

3. grinding process grinding is to remove the rough part of the stone surface, make it more smooth and flat. Grinding process is divided into two stages of coarse grinding and fine grinding: - coarse grinding: use coarse grinding wheel or abrasive disc for preliminary grinding, remove burrs and unevenness left when cutting. -Fine grinding: the use of fine grinding wheels or pads for fine grinding, so that the surface of the stone is more smooth, in preparation for the subsequent polishing. Polishing process should pay attention to control the strength and speed, to avoid damage to the stone.

4. Polishing process is to make the stone surface to achieve a mirror effect of the key steps, usually using polishing machine and polishing agent to complete. Polishing process includes: - preliminary polishing: the use of coarse polishing agent to remove the small scratches left when grinding. -Fine polishing: using fine polishing agent to make the stone surface more bright, to achieve the mirror effect. The polished stone is not only beautiful, but also improves its abrasion and stain resistance.
