在我国石棉水泥制品企业中,绝大多数的制瓦机都是生产小波瓦的。但是,生产中波瓦比生产小波瓦更为经济合理。因为:(一)小波瓦波高14～17毫米,中波瓦波高33毫米,波高小不仅影响屋面排水和美观,而且波高小,断面系数也小。断面系数的大小,又直接影响到瓦的横向强度,断面系数大则强度高。工厂试验证明,采用相同的配料和工艺制度生产的中波瓦其强度约比小波瓦高50～60%左右。(二)小波瓦自重大,消耗的原材料多,工艺过程比较复杂。小波瓦的厚度是8毫米,
In China’s asbestos cement products company, the vast majority of tile makers produce wavelets. However, it is more economical and reasonable to produce wavelets than to produce wavelets in production. Because: (a) wavelet wave height 14 ~ 17 mm, wave height of 33 mm, wave height is not only affect the roof drainage and aesthetics, and wave height is small, the coefficient of section is also small. The size of the section coefficient directly affects the transverse strength of the tile. The large section coefficient has high strength. Factory tests have proved that the strength of Zhongbowa produced using the same ingredients and process system is about 50 to 60% higher than that of the wavelet tile. (b) The wavelet tile is self-contained, consumes many raw materials, and the technological process is relatively complicated. The thickness of the wavelet tile is 8mm.
