一种新型小青瓦机——JWK-170型单轴真空半硬塑弧形瓦瓦机,最近在陕西省新型建材厂(原陕西省实验砖瓦厂)研制成功。该厂在研制过程中,把真空和半硬塑挤出技术引入了弧形瓦的生产,提高了弧形瓦机的生产效率和瓦坯质量,这在国内是首次。用该机生产的经焙烧出窑的成品瓦,表面光滑,断面致密不 A new type of small blue tile machine - JWK-170 single-axis vacuum semi-hard plastic curved tile machine, recently successfully developed in Shaanxi Province, a new type of building materials factory (formerly experimental brick factory in Shaanxi Province). During the development of the plant, vacuum and semi-rigid plastic extrusion technology was introduced into the production of arc-shaped tiles, which increased the production efficiency of arc-shaped tile machines and the quality of billet, which was the first time in China. The finished tile produced by the machine that is baked out of the kiln has a smooth surface and is not dense in section.
