由国家建筑材料工业局建筑材料科学研究院房建材料和混凝土研究所与沈阳新型建材总厂共同承担,用维纶纤维(中弹模量)代石棉制维纶石棉水泥小波瓦(简称 PAC 小波瓦)的研究。为此,这三个承担单位在北京维纶厂的支持下从1985年5月起,开展了以北京维纶厂提供的改性中弹模量维纶纤维代部分石棉试制PAC 小波瓦的研究工作。通过试生产,对原石棉水泥波瓦厂生产工艺稍加调整后,试制出
The building materials and concrete research institute of the Building Materials Science Research Institute of the China Building Materials Industry Bureau and the Shenyang New Building Materials Plant jointly assume the responsibility of using vinylon fiber (inertia modulus) on behalf of asbestos to make PVA asbestos cement and wavelets (PAC for short). Research. To this end, the three undertaking units started to conduct research on the trial of the PAC wavelet tile made by replacing the partially modified asbestos fiber with the modified elastic modulus provided by Beijing Vinylon Plant with the support of Beijing Vinylon Factory. Through trial production, after slightly adjusting the production process of the original asbestos cement and wave plant, trial production
